Appellant Mother and Appellee Father have a child, E.D.2 In August 2014, finding that it was not in E.D.'s best interest to appoint Mother and Father as joint managing conservators, the trial court entered an order that named Mother as the managing conservator with the right to designate E.D.'s primary residence, and ordered Father to pay child support. See Tex. Fam. Code Ann. § 153.132 (West 2014). The trial court also found that Father had a history or pattern of family violence and that, as a result, awarding *103him access to E.D. would endanger E.D.'s physical health or emotional welfare. See id. § 153.004(d) (West Supp. 2017).
Less than two years later, the provisions for conservatorship and visitation took a 180-degree turn. The trial court not only appointed Father as sole managing conservator but also restricted Mother's access to E.D. to six supervised hours of visitation each month. Though the trial court record before us is replete with errors, we are nevertheless hamstrung by applicable legal rules and principles to dismiss this appeal.
Background
On November 17, 2015, Father petitioned to modify the August 2014 order and sought appointment as a joint managing conservator and the imposition of a standard possession order. See id. § 156.101 (West 2014). On February 29, 2016, Father filed a "Motion for Substituted Service" alleging that his attempts to personally serve Mother at her last known address had been unsuccessful and requesting the trial court to permit alternate service under rule 106(b) by delivering the citation and petition to the maternal grandfather. See Tex. R. Civ. P. 106(b) (authorizing the trial court to allow alternate means of service). According to his attached affidavit, process server Matt Pruitt averred that he had made three unsuccessful attempts to personally serve Mother but had also spoken to the maternal grandfather, who had assured Pruitt that if he was served with the citation, he would deliver it to Mother. Although the motion did not comply with the requisites of rule 106(b) -by failing to state the location of Mother's "usual place of business or usual place of abode or other place where [she could] probably be found"-the trial court nonetheless signed an "Order for Substituted Service" granting the motion and ordering the citation to be served by delivering it to the maternal grandfather.
Furthermore, the trial court's signature on the order granting substituted service is curiously dated February 23, 2016, even though the motion for substituted service was not filed until almost a week later, on February 29. And, although the order is dated February 23, it bears a filemark of February 29 and a time stamp of 9:35 a.m., exactly one minute after the motion's time stamp of 9:34 a.m.
On April 29, 2016, the trial court entered an order finding that Mother, "although duly and properly cited, did not appear and wholly made default" and granted the modification sought by Father. The trial court's order gave Father the relief he had pleaded for-it appointed Mother and Father joint managing conservators, awarded Father the exclusive right to designate E.D.'s primary residence, imposed a standard possession order, and ordered Mother to pay child support. See Tex. Fam. Code Ann. §§ 153.134, 153.312 (West 2014).
Then, on June 6, 2016, the trial court entered a judgment nunc pro tunc amending the prior judgment by appointing Father as the sole managing conservator and Mother as the sole possessory conservator. Id. §§ 153.132, 153.192 (West 2014) (addressing rights and responsibilities of a sole managing conservator and a possessory conservator, respectively). The trial court's nunc pro tunc judgment was problematic in two ways. First, in contradiction to Tex. R. Civ. P. 316, which allows only the correction of clerical mistakes in the judgment, it corrected a substantive (purported) "mistake" in the judgment, not a clerical one.3 Second, it granted more *104relief than Father's petition requested. See Simon v. BancTexas Quorum, N.A. , 754 S.W.2d 283, 286 (Tex. App.-Dallas 1988, writ denied) (citing Mullen v. Roberts , 423 S.W.2d 576, 579 (Tex. 1968), for the proposition that "a default judgment must accord with the pleadings"). Unfortunately, while both of these errors arguably constituted error on the face of the record, Mother did not pursue the remedy of restricted appeal. See Tex. R. App. P. 26.1(c), 30.
Granting even further relief beyond Father's pleadings, the nunc pro tunc order also restricted Mother's access to E.D. to six supervised hours on the first Saturday of each month. And, the nunc pro tunc judgment also reiterated that Mother had defaulted after being properly cited to appear.
On August 11, 2016, Mother filed a motion to set aside the default judgment and for a new trial. In it, Mother asserted that she was never properly served, that the Pruitt affidavit did not comply with statutory requirements, and that she did not learn about the case until the local sheriff "showed up at [her] house on June 18, 2016, to remove [E.D.] from [her]."4
In Father's response he argued that Mother's motion was untimely because it was filed more than 30 days after the nunc pro tunc judgment was signed. See Tex. R. Civ. P. 329b(a). Mother argued that her motion was timely because it was filed within two years of the nunc pro tunc judgment. See Tex. R. Civ. P. 329. After conducting a hearing on the matter, the trial court denied Mother's motion by letter ruling dated October 18, 2016, in which the trial court found that her motion was not timely filed. On appeal Mother challenges the trial court's order signed three days later that dismissed her motion for new trial as untimely.
Discussion
As a general rule, the deadline for a party to file a motion for new trial is 30 days after the date the judgment is signed. Tex. R. Civ. P. 329b(a). This 30-day deadline is modified in certain situations, one of which is when service has been authorized through citation by publication. Tex. R. Civ. P. 109, 329.
All lawsuits must be properly served upon the defendant. See Tex. R. Civ. P. 99. Most often, service is effectuated through the personal delivery of a clerk-issued citation and a copy of the petition by a sheriff, constable, process server, or individual who is not a party to the suit. Tex. R. Civ. P. 103, 106(a). But sometimes, as appears to have been the case here, attempts at personal service are unsuccessful, whether because the defendant has purposely avoided service or because the defendant cannot be located. In those situations, the rules of civil procedure provide for alternative means of service, three of which are at issue here: rules 106, 109, and 109a.
Rule 106(b) provides that the party seeking service may submit a motion to the court supported by an affidavit that states (1) the location of the defendant's usual place of business or abode or another *105place where the defendant can probably be found and (2) facts showing that either personal service or service through certified mail was attempted but unsuccessful. Tex. R. Civ. P. 106(b). Upon receipt of such a motion and affidavit,
the court may authorize service (1) by leaving a true copy of the citation, with a copy of the petition attached, with anyone over sixteen years of age at the location specified in such affidavit, or (2) in any other manner that the affidavit or other evidence before the court shows will be reasonably effective to give the defendant notice of the suit.
Tex. R. Civ. P. 106(b).
Service by publication is another alternative. Tex. R. Civ. P. 109. Generally, service by publication is conducted through the placement of a small notice published in the classified section of a local newspaper. In re E.R. , 385 S.W.3d 552, 558 (Tex. 2012). But serving citation by publication is "a last resort," restricted to situations in which a defendant's identity or location is unknown. Id. at 560-61 ("[W]hen a defendant's identity is known, service by publication is generally inadequate.").
In order to obtain citation by publication, a party, his agent, or his attorney must swear under oath that (1) the defendant's residence is unknown to the plaintiff or his attorney, (2) the defendant is a transient person and has not been located, or (3) the defendant is absent from or a nonresident of Texas and citation has been unsuccessfully attempted through personal service.5 Tex. R. Civ. P. 109. Upon presentation of such an oath, the clerk-not the trial court-is required to authorize citation for service by publication. Id. If a defendant is served by publication, only later-prior to granting a default judgment for the plaintiff-will the trial court consider the adequacy of service by publication by reviewing the sufficiency of the diligence exercised in attempting to ascertain the residence or whereabouts of the defendant. Id.
Even in circumstances where citation by publication is warranted, a party may nevertheless elect another form of substituted service. See Tex. R. Civ. P. 109a. Pursuant to rule 109a, "[w]henever citation by publication is authorized, the court may, on motion, prescribe a different method of substituted service, if the court finds, and so recites in its order, that the method so prescribed would be as likely as publication to give the defendant actual notice." Id. A 109a order authorizing a method of substituted service other than publication could authorize service by the very same method as a 106 order authorizing substituted service. See Elam v. Armstrong , No. 03-07-00565-CV, 2008 WL 3539968, at *2 (Tex. App.-Austin 2008, no pet.) (mem. op.) (noting that plaintiff received permission for 109a substituted service to be effected by leaving a copy of the citation and petition with anyone 16 years of age or older at defendant's former residence); Isaac v. Westheimer Colony Ass'n, Inc. , 933 S.W.2d 588, 590 (Tex. App.-Houston [1st Dist.] 1996, writ denied) (noting use of 109a substituted service of citation and petition on defendant's father). But the question of whether substituted service was ordered under rule 106(b) or rule 109a is generally of no practical concern, as long as service was accomplished as ordered.
*106But here, whether substituted service was ordered under rule 106 or 109a is a critical question. Jurisdiction turns on the answer, because when substituted service is ordered under rule 109a, the deadline for filing a motion for new trial is extended from 30 days to two years. Tex. R. Civ. P. 109a (providing that rule 329 shall apply as if citation had been served by publication), 329 (providing that the trial court may grant a new trial upon petition showing good cause filed within two years after the date the judgment was signed). And here, Mother's motion to set aside the default judgment and for a new trial was filed 66 days after the judgment nunc pro tunc was signed. Thus, it was timely-subject to a two-year, rather than 30-day, deadline-only if the trial court ordered substituted service under rule 109a. To determine which rule the trial court invoked here, we must look at the motion requesting substituted service and the order granting it.
In urging us to hold that service was ordered under rule 109a, Mother argues that because Father's motion did not comply with rule 106(b), as discussed above, substituted service could not have been properly ordered under that rule. Although we agree that substituted service was not properly issued under rule 106(b), for purposes of our analysis that fact is irrelevant. Any complaint as to defective service under rule 106(b) was subject to the 30-day deadline for filing a motion for new trial, a deadline that Mother did not meet.6 Because she failed to lodge a timely challenge to any defects in service under rule 106, we focus instead on whether the substituted service was ordered under rule 109a because only if substituted service was ordered by rule 109a would Mother's motion for new trial have been timely filed, preserving her right to appeal here.
Substituted service under rule 109a cannot be ordered unless citation by publication was authorized under rule 109. Tex. R. Civ. P. 109a (providing that "[w]henever citation by publication is authorized, the court may, on motion prescribe a different method of substituted service" and when "the defendant has not appeared, the ... [two-year deadline] shall apply"). Thus, we face two questions: whether service by publication was authorized under rule 109 and, if so, whether the trial court's order authorized substituted service under 109a. The trial court had jurisdiction to consider Mother's motion for new trial only if the answer to both questions is "yes." But based on the record here-especially considering the language of the motion and the order itself-we must hold that the answer to both questions is "no."
As to the first question, to trigger the two-year deadline, service by publication must be "authorized." Id. Rule 109 sets forth the requisites for authorization of service of citation by publication, including that the party, his attorney, or his agent must swear under oath, among other things, that
• the defendant's residence is unknown to the affiant, or
• the defendant is a transient person, or
• the defendant is a nonresident.
*107Tex. R. Civ. P. 109. Father's motion for substituted service did not comply with the requisites of this rule. It was not verified, nor did Father or his attorney sign an affidavit in support of the motion. Assuming that the process server acted as Father's agent, the process server's affidavit did not attempt to address whether Mother's residence was known or unknown to him, except to say that service attempts at an unspecified location or locations were "unsuccessful" and that a telephone number and an address provided to him by Mother's father were not "accurate." And it wholly failed to address whether Mother was a transient person, or whether she was a nonresident. Not only did the motion fail to meet the requisites of rule 109, it specifically sought substituted service under " Rule 106(b)."
As to the second question, any order granting substituted service under rule 109a must recite that the substituted method of service "would be as likely as publication to give defendant actual notice." Tex. R. Civ. P. 109a. The order here contained no such recitation. To the contrary, it stated, "The manner of service ordered will be reasonably effective in giving the Respondent notice of this suit," which echoes the language used in rule 106(b)(2). Tex. R. Civ. P. 106(b)(2) (providing that the court may authorize service in any other manner that the affidavit or other evidence "shows will be reasonably effective to give the defendant notice of the suit"). Finally, the order implicitly purports to grant relief under rule 106(b), rather than rule 109a, by its reference to Father's motion which explicitly requested substituted service under " Rule 106(b)."7
Because the order of substituted service was not authorized by rule 109 and it did not comply with rule 109a, we hold that the two-year period for filing a motion for new trial under rule 329 was never triggered. As such, Mother's motion for new trial-which was not filed within the 30-day deadline-was untimely, and the trial court did not have jurisdiction to consider it. Accordingly, the rules leave us no choice but to overrule Mother's sole issue.
Conclusion
Having held that Mother's motion for new trial was untimely, we dismiss this appeal for lack of jurisdiction.
BIRDWELL, J., filed a dissenting opinion in which MEIER and GABRIEL, JJ., join.
DISSENTING OPINION
WADE BIRDWELL, JUSTICE
Along with the entire court, I share the majority's articulated concerns about the many errors and irregularities apparent on the face of the record in this appeal and the consequentially suspect result in the trial court's judgment and judgment nunc pro tunc, the latter of which effected an *108essentially 180-degree change of custody, possession, and access to a child under three years of age, wholly unsupported by any pleading, based on attempted substituted service that was so incredibly defective as to amount to no service at all. But I respectfully dissent to the majority's holding that we do not have jurisdiction over the appeal. I believe our analysis of the jurisdictional issue should focus on whether Father and the trial court attempted but failed to effect substituted service under rule 109a, instead of deciding that service pursuant to that rule was not authorized because the trial court failed to sign an order containing the recitations required by that rule. By narrowly construing the scope of the remedy available to a party for whom substituted service under rule 109a has been ordered-whether properly or not-the majority denies Mother relief based on Father's failure to strictly comply with substituted service requirements and does so when the record as a whole supports Mother's contention that the trial court attempted to order substituted service pursuant to rule 109a. In doing so, the majority's disposition runs contrary to the directive that we are to liberally construe the rules of civil procedure to resolve matters "with as great expedition and dispatch and at the least expense both to the litigants and to the state as may be practicable." Tex. R. Civ. P. 1 ; In re Bridgestone Americas Tire Operations, LLC , 459 S.W.3d 565, 569 (Tex. 2015) (orig. proceeding); cf. In re J.Z.P. , 484 S.W.3d 924, 925 (Tex. 2016) ; Ryland Enter. v. Weatherspoon , 355 S.W.3d 664, 665 (Tex. 2011) (repeating well-settled principle that we construe rules of appellate procedure liberally to preserve right of appeal on the merits). Therefore, I disagree with the majority solely on the legal question of whether this court has jurisdiction to consider this attempted direct appeal.
Errors and Irregularities Apparent From Face of Record
The majority has accurately set forth many of my concerns with the state of the record in this appeal. But I believe other problems bear recounting.
In the original SAPCR order in which the trial court found that Father had a history or pattern of family violence sufficient to completely deny him access to E.D., the trial court also found that disclosure of the addresses and other identifying information of Mother and the child was "likely to cause [Mother] or the child harassment, abuse, serious harm or injury." Thus, the trial court ordered that such information not be disclosed to Father and extended this nondisclosure to "any custodian of records, including, but not limited to judicial clerks, medical offices, and school offices."
Although in his subsequent motion to modify Father alleged that "[t]he circumstances of the child, a conservator, or other party affected by the order to be modified have materially and substantially changed since the date of rendition of the order to be modified," he did not elaborate what those circumstances were. See Tex. Fam. Code Ann. § 156.101(a)(1) (West 2014). More importantly, his petition never alerted the court to the previous family-violence finding or explained whether he had purged himself of such history or pattern over the intervening fifteen months.1
*109See id. § 153.004(d) (West Supp. 2017) (prohibiting court from granting custodial access to parent shown by a preponderance of the evidence to have a history or pattern of committing family violence within two years preceding filing of or during pendency of SAPCR). Neither did the trial judge address the finding in the modification order or judgment nunc pro tunc.
There is no docket entry for the day the trial court considered and ruled on the motion for substituted service. And although Father's motion states that the initial service attempts occurred in Olney, Young County-which presumably includes the attempt by the process server in which he made contact with Mother's father-the return of service in the record shows that the process server served Mother's father in Seymour, Baylor County. The man who held himself out as Mother's father could have delivered the modification petition to her anywhere in the world, for all we and the trial court could tell from the pretrial record.
At the time of the entry of the original SAPCR order, E.D. had just turned one. She was not yet three when the trial court rendered the modification order. Nevertheless, nothing in the modification order or judgment nunc pro tunc demonstrated that the trial court considered the statutory factors applicable for possession of a child less than three years of age. See id. § 153.254(a) (West Supp. 2017). Nor did the trial court render a prospective order to take effect on the child's third birthday. Id. § 153.254(d) ("The court shall render a prospective order to take effect on the child's third birthday, which presumptively will be the standard possession order.").
The trial court erroneously rendered the judgment nunc pro tunc without any further pleading, motion, or hearing. See Tex. R. Civ. P. 316. Because the judgment nunc pro tunc effected a substantive change, and therefore does not qualify as a judgment nunc pro tunc, it is void because it was signed outside the trial court's plenary power. See Tex. Dep't of Transp. v. A.P.I. Pipe & Supply, LLC , 397 S.W.3d 162, 168 (Tex. 2013).
Both the modification order and judgment nunc pro tunc list Mother's address as "Unknown." Thus, even after the attempted substituted service, the trial court found that no one knew where to find Mother. Pursuant to the trial court's original SAPCR order, Mother's address was not to be disclosed to any judicial clerks. Yet within twelve days of the entry of the judgment nunc pro tunc, the sheriff's department was able to execute the judgment at Mother's residence, taking E.D. from Mother's possession.
Finally, although Father argued in his response to the motion for new trial that Mother's father delivered the petition to her and that Mother had contacted Father a few days after the original modification order, actual notice will not cure defective service for purposes of conveying personal jurisdiction on the trial court to grant a default judgment. See Wilson v. Dunn , 800 S.W.2d 833, 836 (Tex. 1990).
Father Sought Substituted Service Based on His Inability to Locate Mother
It is apparent from the face of the record and the context of Father's motion for substituted service that Father sought the type of substituted service authorized by *110rule 106(b) but for a reason described in rule 109, the publication rule. If Mother had filed a notice of appeal within thirty days of the original modification order, or if she had filed a timely restricted appeal from the original modification order or judgment nunc pro tunc, she would without question be entitled to relief. See, e.g. , id. at 836-37 (citing Medford v. Salter , 747 S.W.2d 519, 520-21 (Tex. App.-Corpus Christi 1988, no writ) (in restricted appeal, construing substance of motion for substituted service that listed and relied solely on rule 109a and reversing default judgment because service was improperly effectuated under either rule 106(b) or rule 109a ) ); cf. Ingram Indus., Inc. v. U.S. Bolt Mfg., Inc. , 121 S.W.3d 31, 35-36 (Tex. App.-Houston [1st Dist.] 2003, no pet.) (holding that service was not defective when heading on citation erroneously referenced rule 106 because rule 99 does not require listing the operable rule or statute on citation itself and service was proper under article 2.11(B) of the Business Corporation Act).
In J.Z.P. , an appeal involving strikingly similar circumstances as this appeal, the Texas Supreme Court considered whether a document entitled "Motion to Reopen and to Vacate Order," filed by the mother after the trial court's plenary jurisdiction had expired, should be construed as a rule 306a motion. 484 S.W.3d at 925 ; see Tex. R. Civ. P. 306a(4), (5) (outlining procedure for obtaining additional time to file postjudgment motion or appeal when adversely affected party or attorney does not receive notice of judgment within twenty days after it is signed). The court of appeals had held that the motion did not extend the trial court's plenary jurisdiction and postjudgment deadlines because it was not captioned as a rule 306a motion. Id. The supreme court held that the court of appeals erred in its holding because "courts should acknowledge the substance of the relief sought despite the formal styling of the pleading," and the mother's pleading "plainly requested relief from the trial court's order on the grounds that she had not been served with citation and had not learned of the trial court's order until a few days before her motion was filed." Id. Accordingly, the supreme court determined whether rule 306a applied to extend postjudgment and appellate deadlines by construing the substance of the mother's request for relief. Id. It further held that "[j]ustice plainly required the trial court and court of appeals to treat [the mother's] motion as extending post-judgment deadlines." Id.
Here, the body of Father's "Motion For Substituted Service"2 reads as follows:
II.
GROUNDS
Service of citation on Respondent has been attempted by personally delivering it to the Respondent at her last known address in Olney, Young County, Texas, but these attempts at service have not been successful as shown by the attached affidavit.
III.
FACTS
Personal Service has been attempted on multiple occasions by Matt Pruitt with no success. Mr Pruitt has been provided phone numbers of the Respondent by the Respondent's father ..., but no one responds to the calls. Despite his diligent efforts, Mr. Pruitt has been unable to locate the Respondent so that personal service can be perfected on the Respondent.
lV.
*111REQUESTED METHOD OF SERVICE
As authorized by Rule 106(b) of the Texas Rules of Civil Procedure, service on the Respondent ... should be made by delivering a copy of the Citation, along with a copy of the Motion to Modify filed herein by [Father], with the Respondent's father....
V.
PRAYER
Movant ... hereby prays that the Court direct that Citation be served on the Respondent ... in the manner described above.
The body of the process server's attached affidavit reads as follows:
Citation for the Respondent ... in this cause was delivered to me by the Petitioner's attorney, Stephen O. Crawford, on January 27, 2016. I have attempted personal service on the Respondent at 4:30 p.m. on January 28, 2016 and such service was not successful. I attempted personal service once again on February 1, 2016 and again was unsuccessful. Service was attempted once again on February 3, 2016. At that time, I was able to make contact with a [name deleted] who represented that he was the father of [Mother]. He gave me an address and phone number for [Mother] but both were found not to still be accurate. [Mother's father] indicated that if I were to leave the papers with him, that he could make sure that [Mother] received them. He indicated that he had regular contact with [Mother]. I feel that by serving the Citation with a copy of the Motion to Modify attached on [Mother's father], that the Respondent ... would receive actual and timely notice of this cause.[3 ]
We must consider the substance of the relief requested in Father's motion in light of the affidavit setting forth why substituted service was necessary. See Tex. R. Civ. P. 106(b), 109 ; cf. J.Z.P. , 484 S.W.3d at 925. Although Father indicated in his motion that he sought service via the method authorized by rule 106(b), he also plainly asserted as a fact supporting service by that method that "[d]espite his diligent efforts, Mr. Pruitt [the process server] ha[d] been unable to locate" Mother. In his affidavit, Pruitt does not indicate that when he encountered Mother's father at the place he had been attempting service, Mother's father affirmed the location was Mother's residence. Instead, Pruitt states that Mother's father gave him another address and a phone number but that those proved to be inaccurate. Thus, nothing in Father's motion or the attached affidavit shows that Mother's address or location was known to the process server, Father, or Father's attorney. And the trial court's original SAPCR order prohibited the disclosure of Mother's address to Father.4
*112The trial court's order authorizing service of Mother via her father does not identify the rule authorizing the substituted service ordered, but merely finds that Father attempted personal service unsuccessfully and that "[t]he manner of service ordered"-delivery to Mother's father-"will be reasonably effective in giving [Mother] notice of this suit."
Whether the motion and affidavit sought substituted service at a known or unknown location is important to determining under which rule Father was attempting to proceed. Rule 106(b)(2) allows for substituted service "[u]pon motion supported by affidavit stating the location of the defendant's usual place of business or usual place of abode or other place where the defendant can probably be found and stating specifically the facts showing that service has been attempted" by delivering it to the defendant in person or mailing it by registered or certified mail, return receipt requested, "at the location named in such affidavit." Tex. R. Civ. P. 106(b). Upon a showing that such attempted service was unsuccessful at that location, the rule outlines one of two methods for substituted service:
(1) by leaving a true copy of the citation, with a copy of the petition attached, with anyone over sixteen years of age at the location specified in such affidavit, or
(2) in any other manner that the affidavit or other evidence before the court shows will be reasonably effective to give the defendant notice of the suit.
Id. Thus, rule 106(b) prescribes a way of effecting substituted service when a process server is unable to serve a defendant at a known, named location. See In re C.L.W. , 485 S.W.3d 537, 541 (Tex. App.-San Antonio 2015, no pet.) ; Garrels v. Wales Transp., Inc. , 706 S.W.2d 757, 759 (Tex. App.-Dallas 1986, no writ) ("We hold that before the trial judge orders substituted service under rule 106, there must be evidence of probative value that the location stated in the affidavit is the defendant's usual place of business or usual place of abode or other place where the defendant can probably be found.").
Neither the motion nor the affidavit identifies Mother's usual place of business or abode or other place where she could probably be found. Thus, substituted service was not "authorized" under rule 106(b).
In contrast, rules 109 and 109a allow substituted service when the defendant's location is unknown. Tex. R. Civ. P. 109, 109a ; cf. Dean v. Hall , No. 03-10-00090-CV, 2010 WL 5463933, at *2 (Tex. App.-Austin Dec. 31, 2010, no pet.) (mem. op.); see Tex. Fam. Code Ann. § 102.010 (West 2014) (providing for service by publication in family law cases). Rule 109 provides as follows:
When a party to a suit, his agent or attorney, shall make oath that the residence of any party defendant is unknown to affiant , ... and that after due diligence such party and the affiant have been unable to locate the whereabouts of such defendant , ... the clerk *113shall issue citation for such defendant for service by publication. In such cases it shall be the duty of the court trying the case to inquire into the sufficiency of the diligence exercised in attempting to ascertain the residence or whereabouts of the defendant or to obtain service of nonresident notice, as the case may be, before granting any judgment on such service.
Tex. R. Civ. P 109 (emphasis added).
Here, Father's motion asserted that even though Pruitt had attempted to serve Mother at her last known address, he had nevertheless been unable to locate her "[d]espite his diligent efforts." This is an almost word-for-word quotation of rule 109. Additionally, Pruitt never averred that the location at which he located Mother's father was in fact Mother's last known address, and he represented that the address and phone number Mother's father gave him were incorrect. Reading the affidavit in its entirety, it is clear that Pruitt averred that substituted service was necessary because he did not know where to find Mother even if he did not expressly state those words. And, again, the trial court's own file containing the original SAPCR order shows that Mother's location was intended to be unknown to Father.
Rule 109a allows the trial court to fashion a method of substituted service other than publication "[w]henever citation by publication is authorized." Tex. R. Civ. P. 109a. The majority concludes that this quoted language means that Father could not have attempted, and the trial court could not have ordered, service under rule 109a because (1) the trial court's order did not include a recitation that the substituted method of service "would be as likely as publication to give defendant actual notice" and (2) Pruitt's affidavit does not aver that Mother's address was unknown to Father. Maj. Op. at 107. But the plain language of rule 109"authorizes" citation by publication when, among other things, a party, his agent, or attorney swears that the defendant's location is unknown to the affiant and the party and despite diligent efforts, he or she cannot locate the defendant. Father clearly proffered the affidavit of the process server as his agent for purposes of establishing the facts necessary to obtain alternate service under rule 109. See Sgitcovich v. Sgitcovich , 150 Tex. 398, 241 S.W.2d 142, 147-48 (1951) (analyzing whether service was proper under rule 109-upon affidavits of two persons with whom server left citation that they did not know where to locate appellant and affidavit of former attorney that did not say whether or not attorney knew appellant's location-in light of whether facts in affidavit were true, stating, "It is not the making of the affidavit, but the truth of it, that is, the existence in fact of the assumed condition , which enables the court to acquire jurisdiction over the person of the defendant by publication." (emphasis added) ), cert. denied , 342 U.S. 903, 72 S.Ct. 291, 96 L.Ed. 676 (1952). That neither Father nor the trial court ensured a proper order was signed does not change that rule 109 -which by its language does not require such a recitation-authorized service by publication upon these facts because of the requisite sworn representation that Mother's location was unknown despite diligent efforts to locate her and effectuate service. It is Father's seeking of and attempt to effect such service based on his inability to locate Mother because he did not (and by order could not) know her address-a permitted reason for seeking service under rules 109 and 109a -that makes rule 329(a) applicable to extend the trial court's plenary power and the appellate deadlines so that we may properly address the merits of Mother's appeal in this case.
*114And, contrary to the majority's conclusion that the trial court's April 29, 2016 docket entry is irrelevant to the jurisdictional analysis, that docket entry is consistent with a conclusion that the trial court attempted, but failed, to properly effectuate service under rules 109 and 109a. It is also consistent with the trial court's duty to inquire into the sufficiency of the diligence exercised in attempting to ascertain Mother's whereabouts, a duty not imposed on the trial court by rule 106(b). Tex. R. Civ. P. 106(b), 109, 109a ; see In re A.Y. , 16 S.W.3d 387, 389 (Tex. App.-El Paso 2000, no pet.).
Thus, mindful of the Supreme Court's admonition in J.Z.P. that Texas courts should look to the substance of the relief sought, not the form of the plea or pleading, the record as a whole shows that Father sought, and the trial court granted, substituted service on the theory that Mother's location was unknown to Father, not that the process server was unable to effectuate service at Mother's usual place of abode or other location where she could probably be found. See Surgitek, Bristol-Myers Corp. v. Abel , 997 S.W.2d 598, 601 (Tex. 1999) (adopting functional approach to determining appealability of venue ruling based on joinder decision). For that reason, I would hold-based solely on the specific facts of this case -that the extended timetable in rule 329(a) applies because Father sought and was authorized to seek service under rule 109 and requested under rule 109a a method of service listed as permissible in rule 106(b). I do not believe this court should hold Father's and the trial court's errors in effecting that substituted service against Mother as the defaulting party when the record must show that Father strictly complied with the rules regarding service to support his default judgment. See Wilson , 800 S.W.2d at 836. Moreover, although Mother may have a remedy through an equitable bill of review, advising her to seek such a remedy at this point-almost two years after entry of the clearly erroneous judgment nunc pro tunc-would result in a further delay of the resolution of a matter that the law demands be handled expeditiously.5 See Tex. R. Civ. P. 1 ; In re Tex. Dep't of Family & Protective Servs. , 210 S.W.3d 609, 613 (Tex. 2006) (orig. proceeding) (op. on reh'g) (noting that in child custody cases "[j]ustice demands a speedy resolution" and granting mandamus relief even though notice of appeal had been filed and issue could have been presented in pending appeal as a remedy but it would have been inadequate).
Conclusion
Because the record as a whole shows that Father sought and obtained substituted service on Mother under rule 109a based on a theory that her location was unknown to him-and because Father's failure to properly effect, and the trial court's failure to properly order, service under that rule or any other cannot cure the many egregious errors in this record-I dissent to the majority's opinion holding that Father's and the trial court's errors constitute a jurisdictional bar to Mother's *115appeal.6 I would consider the appeal on its merits, hold that the trial court erred by failing to grant Mother's motion for new trial, reverse the trial court's modification order and judgment nunc pro tunc, and remand for a new trial. See In re E.R. , 385 S.W.3d 552, 563, 566 (Tex. 2012) (noting that "if service was invalid, a party is entitled to a new trial without showing good cause" and that "[a] complete failure of service deprives a litigant of due process and a trial court of personal jurisdiction; the resulting judgment is void and may be challenged at any time").
