**315*930In this certified appeal, we consider whether the Probate Court retains the statutory authority to make findings pursuant to General Statutes § 45a-608n (b)1 in connection with a petition for special immigrant juvenile status (juvenile status) under 8 U.S.C. § 1101 (a) (27) (J),2 when the minor child who is the **316subject of the petition reaches the age of eighteen years old during the pendency of the petition. The petitioner, Reyna P. A., and her son, Henrry P. B.-P., appeal, upon our grant of their petition for certification,3 from the *931judgment of the Appellate Court, which affirmed the judgments of the Superior Court for Juvenile Matters dismissing their appeals from the decisions of the Probate Court. In re Henrry P. B.-P., 171 Conn. App. 393, 415, 156 A.3d 673 (2017). We agree with their dispositive claim in this appeal, and conclude that the Probate Court did not lose its authority to make juvenile status findings pursuant to § 45a-608n (b) when Henrry turned eighteen years old during the pendency of the petition. Accordingly, we reverse the judgment of the Appellate Court.
The record and the opinion of the Appellate Court set forth the relevant facts and procedural history. "[The petitioner] and her two ... children, Henrry and [his sister], are from Honduras. After her husband and father-in-law were brutally murdered by the same group of individuals, [the petitioner] fled Honduras, seeking safety in the United States and leaving her two minor children behind with their paternal grandmother because they were too young to make the treacherous journey into the [United States]. As the children grew into adolescents, the threats against them began to escalate as well .... Eventually, fearing for their lives, [Henrry and his sister], unbeknownst to relatives, **317decided to embark on their own journey into the United States to find their mother and seek refuge....
"Upon entering the United States in 2015, Henrry and [his sister] were detained by Immigration Customs and Border Patrol and then ultimately released to [the petitioner] in Connecticut. They were seventeen and sixteen years old at that time. Since arriving in Connecticut, both minors have resided with [the petitioner] and the proposed coguardian in this case, [Santos O. R.], and have been enrolled in ... high school, where Henrry recently completed tenth grade.... Both [the petitioner] and [Santos] work full-time to support the needs of Henrry and his [sister]....
"On March 1, 2016, approximately five weeks prior to Henrry's eighteenth birthday, [the petitioner], through counsel, initiated the underlying [action in the Probate Court]. On that date, she filed a petition for removal of guardian, to remove her minor children's father as guardian and affirm herself as guardian, and additionally seeking the appointment of [Santos] as] coguardian.... On that date, she also filed a petition for [juvenile status findings] pursuant to § 45a-608n, to be used in connection with an application to the United States Citizenship and Immigration Services [Immigration Services].... Finally, on that date, [the petitioner] filed a motion for waiver of study by the Department of Children and Families [department] for Henrry, notifying the Probate Court that Henrry would be turning eighteen in approximately five weeks, and that time was of the essence." (Internal quotation marks omitted.) Id., at 396-97, 156 A.3d 673.
" 'On March 23, 2016, the Probate Court issued its first order of notice of hearing in this case indicating that the matter was being set down for a hearing with "no appearance necessary" by the parties on April 22, 2016, a date after Henrry's eighteenth birthday....
**318The Probate Court also [sent notice to] a [department] social work supervisor, ordering [the department] to complete a study for both minors on the petition for removal, and impliedly denying [the petitioner's] motion for the waiver of study by [the department] for Henrry....
*932" 'On April 1, 2016, with Henrry's eighteenth birthday closely approaching, with no [department] study and no hearing date, [the petitioner] filed an emergency petition for findings under § 45a-608n.... In her motion, [the petitioner] requested that the court make findings in connection with her petition for [juvenile status] findings, or, in the alternative, hold an emergency hearing before Henrry's eighteenth birthday, in order to do so.... The attorney for the child, appointed by the Probate Court, Attorney Frank Twohill, having received a copy of the [e]mergency [p]etition, visited with the child and wrote a letter to the court indicating both his support for the [emergency petition], and his availability for an evidentiary hearing ... should the court choose to hold one....
" 'On April 1, 2016, the Probate Court ... denied the emergency petition in a brief written order, indicating [as follows]: "The [e]mergency [p]etition for [f]indings under [§] 45a-608n, dated April 1, 2016, is hereby [denied] by the court. Pursuant to [§] 45a-608n (b), the granting of a petition to remove is a prerequisite to making the requested written findings." ... Henrry subsequently turned eighteen a few days later, before any hearing was ever held in the Probate Court.
" 'On April 22, 2016, [the petitioner] and Henrry ... jointly filed an appeal to the Superior Court ... pursuant to [ General Statutes § 45a-186 (a) ] and Practice Book § 10-76 (a), appealing both the March 23, 2016 order, setting a "no appearance" hearing after Henrry's eighteenth birthday and impliedly denying [the petitioner's]
**319motion for waiver of the study by [the department], and the April 1, 2016 order, denying the emergency petition for findings under [§] 45a-608n.... The [Superior] Court set the matter down for a hearing on May 19, 2016, and another attorney was appointed for Henrry as attorney for the minor child....
" 'On May 19, 2016, the [Superior] Court ... dismissed the appeal from Probate Court on the record, without holding an evidentiary hearing, stating that the [Superior] Court lacked jurisdiction over the appeal, because Henrry was now eighteen years old.... [The petitioner] and Henrry filed [their first appeal] with [the Appellate Court] on June 2, 2016....
" 'On May 31, 2016 ... approximately eight weeks after Henrry's eighteenth birthday, [the department] completed its social study on both Henrry and his sister ... and provided its report to the Probate Court. In its report, [the department] indicated its support for the pending petitions, asking that the court grant the petition to remove the father as guardian, to affirm [the petitioner] as guardian, and to appoint [Santos] as coguardian of Henrry and his [sister]....
" 'On June 3, 2016, the Probate Court issued another order for notice of hearing, this time scheduling an actual hearing date for the underlying petitions for July 19, 2016, but the hearing was set down for [Henrry's sister] ... and not for Henrry.... On June 22, 2016, [the petitioner] filed a motion to schedule hearing or for a dispositive order in Henrry's case.... The Probate Court responded to the motion by scheduling a hearing on the underlying petitions for Henrry on July 19, 2016, along with that of his younger sister ....
" 'On July 19, 2016, the Probate Court held a full hearing for both Henrry and his sister, first entertaining legal argument from counsel on the jurisdictional issue regarding Henrry's case, [given] that he [was] eighteen, **320and then taking testimony on the substantive issues from all the interested parties. The matter was then taken under advisement ....'
"On August 30, 2016, the Probate Court mailed its decision affirming the petitioner *933as sole guardian, but denying her petition for removal of the father as guardian and the appointment of Santos ... as coguardian of Henrry because Henrry was eighteen years old and no longer a minor child. It declined to make the requested juvenile status findings, also because Henrry was age eighteen and no longer a minor child. On September 26, 2016, the petitioner and Henrry filed a second appeal to the Superior Court ... from the Probate Court's August 30, 2016 decision, and on November 1, 2016, that appeal was dismissed. On November 4, 2016, the petitioner and Henrry [filed a second appeal to the Appellate Court]." Id., at 398-401, 156 A.3d 673. The Appellate Court then consolidated the two appeals. Id., at 401, 156 A.3d 673.4
In considering whether the Probate Court had the authority to grant the relief sought by the petitioner and Henrry, the Appellate Court reviewed numerous provisions in "chapter 802h of the General Statutes, which pertains to protected persons, including minors or minor children."5 Id., at 403-404, 156 A.3d 673. The Appellate Court **321stated as follows: "In this case ... on the date the petitioner filed the petitions she, pursuant to [General Statutes] § 45a-606, was Henrry's sole guardian *934because his father was and had been deceased before [Henrry] arrived in the United States. There is no mention in that statute, in § 45a-608n, or in any other of the statutes in part II of chapter 802h, of any statutory authority granted to Connecticut courts to take action with respect to a person who has reached the age of majority. Section 45a-608n by its terms applies solely during the minority of any child." Id., at 405, 156 A.3d 673. The Appellate Court further determined that the "plain language" of the statutes at issue, "particularly § 45a-608n, [does] not provide the Probate Court with authority either to appoint **322a guardian for an individual after his or her eighteenth birthday, or to make juvenile status findings after such eighteenth birthday." Id., at 414, 156 A.3d 673.
Following two decisions from this court construing General Statutes § 46b-129 ; see In re Jose B., 303 Conn. 569, 34 A.3d 975 (2012) ; In re Jessica M., 303 Conn. 584, 35 A.3d 1072 (2012) ; along with one of its own decisions; see In re Pedro J.C., 154 Conn. App. 517, 105 A.3d 943 (2014) ; the Appellate Court then deemed itself "constrained to conclude" that the present case was rendered moot "after Henrry reached the age of majority [because] the Probate Court lacked statutory authority to appoint a coguardian for him and to make the juvenile status findings permitted by § 45a-608n."6 In re Henrry P. B.-P., supra, 171 Conn. App. at 410, 156 A.3d 673. Accordingly, over a dissent by Judge Lavine, the Appellate Court affirmed the Superior Court's judgments dismissing the probate appeals.7
*935Id., at 411-15, 156 A.3d 673. This certified appeal followed. See footnote 3 of this opinion.
**323On appeal, the petitioner and Henrry claim, inter alia, that the Appellate Court improperly determined that it was bound by our decisions in In re Jose B., supra, 303 Conn. at 582, 34 A.3d 975, and In re Jessica M., supra, 303 Conn. at 588-89, 35 A.3d 1072, in concluding that the Probate Court lacked the authority to grant them the relief they sought after Henrry reached the age of majority. The petitioner and Henrry argue that those cases are distinguishable because they were not juvenile status cases but, rather, concerned whether the court had the statutory authority under § 46b-129 (a) and (j) to commit a person over the age of eighteen to the custody of the department. To this end, the petitioner and Henrry emphasize that In re Jose B. and In re Jessica M. predate the 2014 enactment of the § 45a-608n, the juvenile status findings statute, and that they do not seek Henrry's commitment to, or any services from, the department. We agree with the petitioner and Henrry, and conclude that the Probate Court did not lose its statutory authority to make juvenile status findings pursuant to § 45a-608n after Henrry reached the age of majority during the pendency of the proceedings.8
**324In considering whether the Probate Court had the statutory authority to make juvenile status findings pursuant to § 45a-608n after Henrry reached the age of majority during the pendency of the proceedings, we are mindful that the "Probate Court is a court of limited jurisdiction prescribed by statute, and it may exercise only such powers as are necessary to the performance of its duties. ... As a court of limited jurisdiction, it may act only when the facts and circumstances exist upon which the legislature has conditioned its exercise of power.... Such a court is without jurisdiction to act unless it does so under the precise circumstances and in the manner particularly prescribed by the enabling legislation." (Citations omitted; internal quotation marks omitted.) Heussner v. Hayes, 289 Conn. 795, 802-803, 961 A.2d 365 (2008) ; see also In re Bachand, 306 Conn. 37, 59-61, 49 A.3d 166 (2012) (Probate Court's limited jurisdiction creates constraints over its authority, even with respect to matter over which Superior Court has concurrent jurisdiction). Thus, whether the Probate Court had jurisdiction to render the decree challenged by the commissioner presents a question of statutory interpretation. See In re Bachand, supra, at 42, 49 A.3d 166. Consequently, whether the Probate Court had the statutory authority to provide the relief requested presents a question of law over which our review is plenary.9 See, e.g., In re Jose B., supra, 303 Conn. at 580, 34 A.3d 975.
*936"When construing a statute, [o]ur fundamental objective is to ascertain and give effect to the apparent intent **325of the legislature.... In other words, we seek to determine, in a reasoned manner, the meaning of the statutory language as applied to the facts of [the] case, including the question of whether the language actually does apply.... In seeking to determine that meaning, General Statutes § 1-2z directs us first to consider the text of the statute itself and its relationship to other statutes. If, after examining such text and considering such relationship, the meaning of such text is plain and unambiguous and does not yield absurd or unworkable results, extratextual evidence of the meaning of the statute shall not be considered.... When a statute is not plain and unambiguous, we also look for interpretive guidance to the legislative history and circumstances surrounding its enactment, to the legislative policy it was designed to implement, and to its relationship to existing legislation and common law principles governing the same general subject matter .... The test to determine ambiguity is whether the statute, when read in context, is susceptible to more than one reasonable interpretation." (Internal quotation marks omitted.) Gonzalez v. O & G Industries, Inc., 322 Conn. 291, 302-303, 140 A.3d 950 (2016).
We begin with the language of § 45a-608n (b), which provides: "At any time during the pendency of a petition to remove a parent or other person as guardian under section 45a-609 or 45a-610, or to appoint a guardian or coguardian under section 45a-616, a party may file a petition requesting the Probate Court to make findings under this section to be used in connection with a petition to ... Immigration Services for designation of the minor child as having special immigrant juvenile status under[ 8 U.S.C. § 1101 (a) (27) (J) ]. The Probate Court shall cause notice of the hearing on the petition to be given by first class mail to each person listed in subsection (b) of section 45a-609, and such hearing may be held at the same time as **326the hearing on the underlying petition for removal or appointment. If the court grants the petition to remove the parent or other person as guardian or appoint a guardian or coguardian, the court shall make written findings on the following: (1) The age of the minor child; (2) the marital status of the minor child; (3) whether the minor child is dependent upon the court; (4) whether reunification of the minor child with one or both of the minor child's parents is not viable due to any of the grounds sets forth in subdivisions (2) to (5), inclusive, of section 45a-610 ; and (5) whether it is not in the best interests of the minor child to be returned to the minor child's or parent's country of nationality or last habitual residence."10 (Emphasis added.)
As the Appellate Court observed, the text of § 45a-608n (b) seemingly applies only to persons under the age of eighteen, insofar as it speaks to various court actions, such as the removal or appointment of guardians, or termination of parental *937rights, with respect to the "minor child," a term specifically defined by General Statutes § 45a-604 (4) to mean "a person under the age of eighteen ...." See In re Henrry P. B.-P., supra, 171 Conn. App. at 404, 156 A.3d 673 ; see also General Statutes § 45a-604 (5) ( " '[g]uardianship' means guardianship of the person of a minor"). The authority conferred by § 45a-608n (b) with respect to the juvenile status findings specifically also reasonably may be read to be limited to **327persons under eighteen years old, insofar as it expressly requires the court to make those findings upon the grant of the "petition to remove the parent or other person as guardian or appoint a guardian or coguardian"-thus plausibly suggesting, consistent with the Probate Court's reading of the statute, that such a grant is a prerequisite to the juvenile status findings.
There is, however, another reading of the statute that is at least equally as reasonable; we, therefore, resort to extratextual sources to aid our construction of § 45a-608n (b). First, the petition for juvenile status findings may be filed "at any time during the pendency of a petition to remove a parent or other person as guardian" under General Statutes §§ 45a-609 or 45a-610, or during the pendency of a petition "to appoint a guardian or coguardian" under General Statutes § 45a-616. General Statutes § 45a-608n (b). The statute is similarly flexible with respect to the timing of the hearing on the juvenile status petition, insofar as it need not be held at the same time as the underlying petition. See General Statutes § 45a-608n (b) ( "such hearing may be held at the same time as the hearing on the underlying petition for removal or appointment" [emphasis added] ). Finally, the statute reasonably may be read merely to require the Probate Court to make the written findings with respect to juvenile status upon the grant of the underlying guardianship petitions, but not limit its authority to make such findings to cases involving such grants, insofar as there is no language expressly conditioning the Probate Court's authority to make juvenile status findings on the grant of the underlying petition.
Indeed, reading § 45a-680n to add such restrictive language would run afoul of the well established maxim that, "[a]s a general matter, this court does not read language into a statute.... [W]e are bound to interpret legislative intent by referring to what the legislative text contains, not by what it might have contained."
**328Citation omitted; internal quotation marks omitted.) State v. George J., 280 Conn. 551, 570, 910 A.2d 931 (2006), cert. denied, 549 U.S. 1326, 127 S.Ct. 1919, 167 L.Ed.2d 573 (2007). Adding such a restriction also would be inconsistent with General Statutes § 45a-605 (a), in which the legislature directs that the statutory scheme that includes § 45a-608n"be liberally construed in the best interests of any minor child affected by them, provided the requirements of such sections are otherwise satisfied." Finally, the express mention of 8 U.S.C. § 1101 (a) (27) (J), the federal juvenile status statute, in § 45a-608n (b) calls to mind the maxim that, "[i]n cases in which more than one [statutory provision] is involved, we presume that the legislature intended [those provisions] to be read together to create a harmonious body of law ... and we construe the [provisions], if possible, to avoid conflict between them." (Internal quotation marks omitted.) Cardenas v. Mixcus, 264 Conn. 314, 326, 823 A.2d 321 (2003) ; see also id., at 322-23, 823 A.2d 321 ("[w]e presume that laws are enacted in view of existing relevant statutes ... [and] we read each statute in a manner that will not thwart its intended purpose or lead to absurd results" [internal quotation marks omitted] ).
Authorizing the Probate Court to make juvenile status findings with respect to a *938minor child who has turned eighteen years old during the pendency of the petition is entirely consistent with the overarching purpose of § 45a-608n (b), which is to facilitate our state courts' responsibilities with respect to juvenile status petitions brought to Immigration Services under 8 U.S.C. § 1101 (a) (27) (J), the federal statute that is expressly cited in the text of § 45a-608n (b). Given this statutory purpose, a review of the federal statutory scheme is instructive. "Congress created [juvenile status] to permit immigrant children who have been abused, neglected, or abandoned by one or both of their parents to apply **329for lawful permanent residence while remaining in the United States. See [ 8 U.S.C. § 1101 (a) (27) (J) (2012) ]; 8 C.F.R. § 204.11 (2009).11 '[C]hild' under the Federal statute is defined as an unmarried person under the age of twenty-one. 8 U.S.C. § 1101 (b) (1) [2012]. Before an immigrant child can apply for [juvenile status], she must receive the following predicate findings from a 'juvenile court': (1) she is dependent on the juvenile court; (2) her reunification with one or both parents is not viable due to abuse, neglect, or abandonment; and (3) it is not in her best interests to return to her country of origin. 8 U.S.C. § 1101 (a) (27) (J) (i) [2012]. Once these special findings are made, an application and supporting documents may be submitted to [Immigration Services]. An application for[juvenile status] must be submitted before the immigrant's twenty-first birthday. 8 C.F.R. § 204.11 [2009]." (Emphasis added; footnotes added and omitted.) Recinos v. Escobar, 473 Mass. 734, 734-35, 46 N.E.3d 60 (2016).
"The [f]ederal statute requires a juvenile court to make special findings before an immigrant youth can apply for [juvenile status] and lawful permanent residence.... The [s]tate and [f]ederal proceedings are distinct from each other. The process for obtaining [juvenile status] is a unique hybrid procedure that directs the collaboration of state and federal systems.... Pursuant to 8 C.F.R. § 204.11, '[j]uvenile court' is defined as 'a court located in the United States having jurisdiction under [s]tate law to make judicial determinations about the custody and care of juveniles.' When determining which court qualifies as a juvenile court under the [f]ederal statute, it is the function of the [s]tate court and not the designation that is determinative."
**33012 (Citations omitted; footnote omitted; internal quotation marks omitted.) Id., at 737-38, 46 N.E.3d 60 ; see H.S.P. v. J.K., 223 N.J. 196, 209-11, 121 A.3d 849 (2015) (reviewing federal juvenile status statutes); see also Marcelina M.-G. v. Israel S., 112 App.Div.3d 100, 106-109, 973 N.Y.S.2d 714 (2013).
Significantly, although the federal implementing regulation, 8 C.F.R. § 204.11 (c), *939requires that the juvenile status "application must be submitted before the child's twenty-first birthday," federal law provides that "[t]he child will not'age-out' of [juvenile status] on account of turning twenty-one while his or her application is under consideration with [Immigration Services]." (Emphasis added.) Recinos v. Escobar, supra, 473 Mass. at 739, 46 N.E.3d 60, citing William Wilberforce Trafficking Victims Protection Reauthorization Act of 2008, Pub. L. No. 110-457, § 235 (d) (6), 122 Stat. 5044.
Although the federal age cap for juvenile status, namely, twenty-one years old, is greater than our state's relevant operative statutory definition of a minor child, namely, a person younger than eighteen years old; see General Statutes § 45a-604 (4) ; the legislative history of § 45a-608n further counsels in favor of a broader reading of that statute with respect to those persons eligible to obtain the predicate state court findings necessary **331to render available the federal immigration benefits of juvenile status. The legislature enacted § 45a-608n in Number 14-104, § 8, of the 2014 Public Acts.13 Although floor debate about this provision was virtually nonexistent, our review of the testimony submitted to the Joint Standing Committee on the Judiciary in support of the bill ultimately enacted as § 45a-608n indicates that the legislature intended to address discrepancies in the state statutory scheme that were frustrating the availability of the federal immigration benefit. See, e.g., Butts v. Bysiewicz, 298 Conn. 665, 687, 5 A.3d 932 (2010) ("testimony before legislative committees may be considered in determining the particular problem or issue that the legislature sought to address by the legislation" [internal quotation marks omitted] ). For example, Attorney Edwin Colon testified, on behalf of the Center for Children's Advocacy, that the proposed "statutory changes will provide children with increased access to protection under existing federal law [by] expressly authorizing the court to make these findings ...." Conn. Joint Standing Committee Hearings, Judiciary, Pt. 3, 2014 Sess., pp. 1221-22. Attorney Colon emphasized that the bill allowed children to file a motion seeking the necessary findings even after the issuance of a decree, and advised the legislature that it "should apply retroactively to any child who can still benefit from [juvenile status] federal protection." Id., p. 1222. Testifying in further support of the bill, Judge Paul Knierim, Probate Court Administrator, made clear his desire that the legislation be inclusive and "cautious." Id., pp. 904-907. Judge Knierim stated that "probate courts have been seeing [juvenile status] petitions under this statutory framework and the intent ... would be to make it clear that Connecticut probate courts have legislative authorization when handling these types of **332children's matters to also make these findings."14 Id., p. 906. Similarly, Megan R. Naughton, an immigration attorney in private practice, described to the legislature the necessity of using "the appropriate language ... in the special findings" from the Probate Court in a case in which she had to refile for juvenile *940status shortly before her client turned twenty-one years old. Id., p. 1223. In the absence of clear and unambiguous statutory language to the contrary, we decline to frustrate the purpose of § 45a-608n, namely, to facilitate access to the state court findings necessary as a predicate step toward federal juvenile status, and we conclude that the Probate Court was not divested of statutory authority to make those findings when Henrry turned eighteen years old during the pendency of the petition.15 **333We disagree with the Appellate Court's conclusion that our decisions in In re Jose B., supra, 303 Conn. at 569, 34 A.3d 975, and In re Jessica M., supra, 303 Conn. at 584, 35 A.3d 1072, dictate a contrary result. In In re Jose B., the minor child filed a petition with the trial court pursuant to § 46b-129 (a), "seeking to have himself adjudicated as neglected and as an uncared-for youth," along with an order of temporary custody and an emergency commitment to the custody of the department. Id., at 570-71, 34 A.3d 975. The trial court dismissed the petition as moot because "two days after he filed it, he reached his eighteenth birthday." Id., at 571, 34 A.3d 975. On appeal, we determined that In re Jose B. presented the question of "whether the trial court has statutory authority pursuant to § 46b-129 (a) to adjudicate a person who has reached the age of eighteen years as neglected or uncared-for, and to commit such a person to the care of the department pursuant to § 46b-129 (j)." Id., at 580, 34 A.3d 975.
Reading together the relevant statutory provisions, namely, § 46b-129 (a), and the definitions of "[c]hild" or "[y]outh" in General Statutes (Rev. to 2009) § 46b-120 (1) and (2), and "neglected" or "uncared for" in General Statutes (Rev. to 2009) § 46b-120 (9) and (10),16 we concluded that "it is clear that the legislature intended that the *941trial court would have statutory **334authority to adjudicate a person neglected or uncared-for only if the person is a child or youth, i.e., the person is under the age of eighteen years. There is no indication in the statutory scheme that the legislature contemplated that, as long as the petition was filed before the subject of the petition reached his eighteenth birthday, the trial court could render a 'retroactive' adjudication after that date. As the [2009] revision of § 46b-120 (1) indicates, when the legislature intends that a person will be considered a child for certain purposes after the person has reached the age of eighteen years, it knows how to make that intention clear. See General Statutes [Rev. to 2009] § 46b-120 (1) (defining " '[c]hild' " differently for different circumstances). Accordingly ... the trial court lacked statutory authority to adjudicate the petitioner neglected or uncared-for after his eighteenth birthday. It necessarily follows that the trial court lacked statutory authority to provide the petitioner with dispositional relief pursuant to § 46b-129 (j)...." (Footnote omitted.) In re Jose B., supra, 303 Conn. at 581-82, 34 A.3d 975. We further concluded that, "because the trial court lacked such statutory authority, that court properly concluded that the petitioner's petition was rendered moot when he reached his eighteenth birthday." (Emphasis omitted.) Id., at 582, 34 A.3d 975.
Similarly, in In re Jessica M., supra, 303 Conn. at 588, 35 A.3d 1072, the companion case to In re Jose B., this court rejected the petitioner's claim that "an adjudication of neglect pursuant to § 46b-129 (a) would enable her to seek ... juvenile status from the federal government," meaning that, under the collateral consequences doctrine, "her claim for an adjudication of neglect was not moot even if the trial court could not grant dispositional relief pursuant to § 46b-129 (j)." The court emphasized that, "not only did the trial court lack statutory authority to provide dispositional relief to the petitioner after she reached her eighteenth birthday, it also lacked statutory authority to adjudicate the petitioner neglected or uncared-for. The collateral consequences doctrine cannot confer statutory **335authority on the trial court that is otherwise lacking." Id., at 588-89, 35 A.3d 1072.
We agree with the petitioner and Henrry that In re Jose B. and In re Jessica M. are not controlling in the present appeal. We acknowledge that this court observed in In re Jose B. that the legislature can use a more expansive definition of the term "child" to broaden the court's statutory authority in certain areas; In re Jose B., supra, 303 Conn. at 581, 34 A.3d 975 ; which was a point that the Appellate Court found persuasive in the present case. See In re Henrry P. B.-P., supra, 171 Conn. App. at 412, 156 A.3d 673. Nevertheless, In re Jose B. and In re Jessica M. predate the enactment of § 45a-608n in 2014, with its specific grant of authority to make the findings factual incident to juvenile status and its express acknowledgment of the federal juvenile status scheme, which has age eligibility that extends beyond the age of eighteen years old that typically demarks the end of the court's authority over the guardianship of minors. Accordingly, the Appellate Court improperly deemed In re Jose B. and In re Jessica M. dispositive of the present case,17 insofar as the Probate *942Court's authority to make the juvenile status findings under § 45a-608n does not terminate on the minor's eighteenth birthday.18 The Appellate **336Court, therefore, improperly affirmed the judgments of the Superior Court dismissing the probate appeals.19 *943The judgment of the Appellate Court is reversed and the case is remanded to that court with direction to reverse the judgments of the Superior Court and to remand the case to the Superior Court for further proceedings according to law.
In this opinion the other justices concurred.
