h Under our guardianship statutes, a court may terminate a guardianship if it is no longer necessary or if it is in the ward’s best' interest. We hold that a guardianship is no longer necessary when a fit parent who consented to a guardianship revokes consent. Here, the circuit court’s ruling that the father, David Lineham, was unfit was clearly erroneous. Therefore, the court should have granted David’s petition to terminate a guardianship to which he had earlier consented. We reverse the order keeping the guardianship in place and remand for the court to enter an order terminating the guardianship and placing W.L. in David Lineham’s custody.
I. Relevant Facts
The relevant facts in this case were developed at hearings stemming from two petitions to terminate a guardianship. David Lineham and Sarah Hyde started dating in 122007. The, two lived in a suburb of Washington D.C. in northern Virginia. Sarah became pregnant. Their child, W.L., was born in March 2008. At that time, David and Sarah lived with David’s parents, but they moved into their own apartment in July 2009.
Sarah’s parents, Dennis, and Anna Hyde, also lived in the area. (The Hydes also *131had another home in Arkansas). In early fall of 2009, the Hydes had guardianship papers prepared and they presented them to David and Sarah for consent. David testified that he and Sarah consented to the Hydes’ exercising a guardianship over W.L. so that W.L. would be able to have access to health insurance and daycare under Dennis Hyde’s military benefits. W.L. continued to reside with David and Sarah. In December 2009, the Logan County Circuit Court entered an order appointing the Hydes as guardians over W.L. The Hydes eventually moved to Arkansas in July 2010. W.L. moved with them and has lived with Dennis and Anna ever since.1
David Lineham filed a petition to terminate the guardianship in December 2010, a year after the guardianship’s inception and five months after the Hydes had moved to Arkansas. It took the circuit court over a year — until January 2012 — to hold a hearing in the case.2 At this hearing, David testified that he never intended to give up his parental rights to W.L. He also testified that in September 2010 he had married Danielle Lineham, |athat both he and Danielle were employed, and that they shared a two-bedroom apartment. However, David also testified that he had .visited W.L. only twice in Arkansas and that his telephone communication with her was sporadic. David also admitted that he had not provided the Hydes with any financial assistance since they had become W.L.’s guardians.
In April 2012, the circuit court entered an order denying David’s petition and kept the guardianship in place. The court found that the guardianship was still necessary in order to maintain W.L.’s access to food, clothing, and financial support, which David had not provided. The court further found that David and his new wife Danielle “laek[ed] a meaningful relationship” with W.L. The court set a visitation schedule whereby David could visit W.L. in Arkansas and permitted W.L. to visit David in Virginia during the summer. David did not appeal from this order.
The present round of litigation started in October 2012 when Sarah, W.L.’s mother, filed a petition to terminate her parents’ guardianship over W.L. David subsequently filed a second petition to terminate the guardianship. These motions were filed in the underlying guardianship case, which had been assigned to the probate division of the Logan County Circuit Court. Sarah also filed a petition for declaratory judgment and establishment of paternity, a case which had been assigned to the domestic-relations division of the same court. Eventually all parties — David, Sarah, and the Hydes (guardians) — agreed that Sarah would file a petition for custody in the domestic-relations Lease and that the case would then be consolidated into the probate matter. An order was entered to that effect in November 2012. David then filed a counterclaim for custody.
The circuit court held a two-day hearing in August 2013 to decide the consolidated petitions to terminate the guardianship and, if necessary, the petitions for custody. David testified that he and his wife still lived-in Virginia. Since the last hearing, he had made eighteen trips to Arkansas to visit W.L. and had made multiple phone calls to her each week. David worked full-*132time at a car dealership, making a gross salary of between $5000 and $5500 per month. David’s wife, Danielle, testified that she also worked full-time and made around $35,000 per year. In essence, David addressed the court’s concern from the previous hearing that he lacked significant contact with his daughter and did not have a meaningful relationship with her.
Sarah testified that since the last hearing she had had another child and later married the father, William Lawson. Sarah had sporadic residency, but now lived in a trailer on the Hydes’ property in Arkansas. She said she paid rent to her parents by “working on the farm.” Neither she nor her husband owned a vehicle. She had a suspended driver’s license in Virginia. She did not have a job and testified that she had $1.16 in her bank account. Finally, Sarah admitted that she had two felony drug convictions for possession of heroin and Dilaudid. Those convictions were in Virginia, where she was also facing a probation-revocation hearing the following month.
The court also heard testimony from Dennis and Anna Hyde. They testified that David, had still not provided any financial support for W.L. while they had been her | ¡jguardians. Anna testified that David had done “all that he’s been asked to do” and that “he’s been an actively engaged father.” She also stated that he had provided clothing and toys for W.L. and had developed a relationship with her. Despite this, both of the Hydes testified that they believed the guardianship was necessary in regards to David, but not as to their daughter, ■ Sarah. In other words, they thought their guardianship should be terminated if the court were to return custody to Sarah; but if the court were to return custody to David, they thought their guardianship should stay in place.
After hearing the testimony, the court took the case under advisement and later issued a letter opinion and order. First, the court found that “from its previous ruling that David Lineham was determined to be unfit, although specific wording to that effect was not used.” Second, the court found for the first time that Sarah was unfit and that David remained unfit. Finally, the court found that termination of the guardianship was not in W.L.’s best interest. Accordingly, the court kept the guardianship in place and denied and dismissed David and Sarah’s petitions to terminate the guardianship and petitions for custody. David has appealed; notably, Sarah has not.3
II. Termination of Guardianship
Guardianships are special proceedings that are governed by statute. Hetman v. Schwade, 2009 Ark. 302, 317 S.W.3d 559. Under the guardianship statute, a guardianship can be terminated “[i]f, for any other reason, the guardianship is no longer necessary or for | fithe best interest of the ward.” Ark.Code Ann. § 28-65-401(b)(3) (Repl.2012). Termination-of-guardianship cases have been in a recent state of flux. We tried to bring some sense to this area of the law in Graham v. Matheny. However, while the Graham court acknowledged that termination-of-guardianship cases were governed by a disjunctive statute, it noted that if the ward is a child, the circuit court must still consider best interest, which has the effect of turning the test into a conjunctive one— *133the or becomes an and. 2009 Ark. 481, at 14-15, 846 S.W.3d 273, 281.
We attempted to clarify the guardianship analysis in In re Guardianship of S.H. (1), 2012 Ark. 245, 409 S.W.3d 307 (In re S.H. (1)). There, we recognized and reaffirmed a fit parent’s “fundamental liberty interest in the care, control, and custody of her child.” 2012 Ark. 245, at 8-9, 409 S.W.3d at 313. The United States Supreme Court acknowledged this principle in Troxel v. Granville, 530 U.S. 57, 120 S.Ct. 2054, 147 L.Ed.2d 49 (2000), and in accordance we have adopted a presumption that a fit parent acts in his or her child’s best interest. See, e.g., Linder v. Linder, 348 Ark. 322, 72 S.W.3d 841 (2002).
The issue in In re S.H. (1) was whether a fit parent who consented to a guardianship had the burden to prove, under Graham, both prongs of the statutory test in order for the court to terminate the guardianship. We reasoned that “parents who have not been found unfit do not relinquish their fundamental liberty interest in raising their children by consenting to a guardianship.” 2012 Ark. 245, at 14, 409 S.W.3d at 316. Accordingly, we adopted a two-step, burden-shifting procedure when a fit parent who consented to a guardianship later moves to terminate that guardianship:
|7A natural parent who has not been deemed unfit is entitled to the presumption that he or she is acting in the child’s best interest, even after consenting to a guardianship. Therefore, when a natural parent, who has not been deemed unfit and who has consented to a guardianship, files a petition to terminate that guardianship, that parent must put forth evidence that the guardianship is no longer necessary. Once the court is satisfied that the conditions necessitating the guardianship have been removed, the guardians shoulder the burden of rebutting the presumption that termination is in the child’s best interest.
Id. at 15, 409 S.W.3d at 316. We remanded the case for the circuit court to reevaluate the case applying this procedure.
When that case returned to us after remand, we clarified the test in two ways. See In re Guardianship of S.H. (2), 2015 Ark. 75, 455 S.W.3d 313 (“In re S.H. (2)”). First, we said that a fit parent meets the burden that a guardianship is no longer necessary under the statute by revoking consent. Id. at 14, 455 S.W.3d at 322. Second, we said that the guardians can rebut this presumption by proving best interest by clear and convincing evidence. Id. We noted that this conjunctive burden-shifting-test was inconsistent with the disjunctive statute, but nevertheless ruled that we were bound by the law-of-the-case doctrine. Ultimately, we reversed the circuit court’s order keeping the guardianship in place and ordered the court to .return the child to her mother, who was fit.
We are not bound by law of the case here and can return to the statute’s plain language, which states that “a guardianship may be terminated by court order ... [i]f, for any other reason the guardianship is no longer necessary or for the best interest of the ward.” Ark.Code Ann. § 28-65-401(b)(3). Parents have a fundamental right to raise their children. We will not lightly intrude on this fundamental right. We have already said that a guardianship is no longer necessary once a fit parent revokes an earlier-given consent. | sThis is because a fit parent is presumed to be acting in the child’s best interest. By petitioning to terminate the guardianship and revoking consent, the fit parent, who has the child’s best interest at heart, informs the court that the guardianship is no longer necessary. That is sufficient to meet the statutory requirement where the *134court “may5’ terminate the guardianship. In other words, a guardianship is no longer necessary — per the statute — when a fit parent revokes consent. The fit parent does not have to prove anything else. The statute does contain another method for the guardianship to be terminated, that is, by showing it is no longer in the ward’s best interest. However, given that the legislature has created a disjunctive test, the parent can move to terminate under either prong.
This ruling is consistent with the statutory text and a fit parent’s fundamental liberty interest in the care, control, and custody of his or her child. Furthermore, the burden of proof does not and cannot shift to the guardians when a guardianship is terminated based on a fit parent’s revocation of consent. Simply put, a fit parent’s decision regarding his or her children is conclusive. See Troxel, 530 U.S. at 68-69, 120 S.Ct. 2054 (“[S]o long as a parent adequately cares for his or her children (■ie., is fit), there will normally be no reason for the State to inject itself into the private realm of the family to further question the ability of that parent to make the best decisions concerning the rearing of that parent’s children.”).
To the extent Graham, In re S.H. (1), and In re S.H. (2) are in conflict with this decision, they are overruled. The judicially created tests from our past guardianship cases |9have moved termination-of-guardianship cases too far from the statute and, as In re S.H. (2) and this case have shown, result in circuit courts unnecessarily delaying the return of children to a fit parent’s custody. For these reasons, it would be wrong to adopt the dissent’s argument that we should affirm since the circuit court properly applied the then existing legal test and has unbridled discretion. There is a reason we review questions of fact, and sometimes, upon review, we are left with a definite and firm conviction that a mistake has been made. Such is the case here. In short, our judicially created, two-step tests are ineffective to protect a fit parent’s fundamental rights and are divorced from the statutory text. The best path is to abandon the tests and bring termination-of-guardianship cases in line with the statute.
III. Discussion
Here, the circuit court made two rulings regarding David’s fitness. First, the court retroactively said David had been unfit at the first termination-of-guardianship hearing, although never mentioning it in its first order. Second, the court ruled that David continued to be unfit at the second termination-of-guardianship hearing. We review probate proceedings de novo, but we will not reverse a finding of fact by the circuit court unless it is clearly erroneous. Devine v. Martens, 371 Ark. 60, 263 S.W.3d 515 (2007). A finding is .clearly erroneous when, although there is evidence to support it, the reviewing court is left with a definite and firm conviction that a mistake has been made. Id. When reviewing the proceedings, we give due regard to the opportunity and superior position of 110the probate judge to determine the credibility of the witnesses. Id. Both of the circuit court’s findings regarding David’s unfitness are clearly erroneous.
The court had no authority to retroactively declare David unfit. Here is an excerpt from the circuit court’s letter opinion:
An examination of the prior orders of this court ... does not reveal that this court has expressly found either David Lineham or Sarah Hyde to be unfit. However, despite the arguments of David Lineham that no such'finding has been made to him, the court believes *135that such a finding was made as to him in this court’s letter opinion of February-28, 2012, (which was incorporated into the Order filed on April 9, 2012). Although the specific word unfit was not used, an examination of this court’s letter opinion reveals [the contrary].
The court went on to note that, at the first hearing, it found that David had not provided food, clothing, or financial support to W.L. and did not demonstrate a meaningful relationship with W.L., although no court had. ordered him to provide support nor did the Hydes request it. These findings, according to the circuit court, are “clearly a finding! ] of unfitness, even if not so worded.” In short, the court ruled in its November 2018 order that its April 2012 order contained a finding of unfitness.
Under Arkansas Rule of Civil Procedure 60(a), the circuit court may modify or vacate an order or judgment “[t]o correct errors or mistakes or to prevent the miscarriage of justice ... within ninety days of it having been filed with the clerk.” The court, therefore, loses jurisdiction to modify an order under Rule 60(a) unless it does so within ninety days. Slaton v. Slaton, 380 Ark. 287, 956 S.W.2d 150 (1997).4 For example, in \uSlaton, by a September 1991 divorce decree the court originally granted the father sole custody; however, in March 1992, the court modified the decree by declaring that the father and mother would share joint custody. We reversed, holding, in part, that the court “did not have jurisdiction to enter its March 5, 1992 order pursuant to Ark. R. Civ. P. 60.” Id. at 296, 956 S.W.2d at 154. Likewise, in this case, the court did not have jurisdiction to modify the April 2012 order via its November 2013 order. In short, the circuit court could not retroactively declare David unfit.5
The court also held in its second order that David “remains unfit as a parent.” This finding is clearly erroneous. The court outlined the specific reasons for this finding in its letter opinion, reasons that include the following:
• David refused to sit with the Hydes during W.L.’s kindergarten graduation ceremony;
• David testified that he had spent $8000 on W.L. during his visits to Arkansas, yet Dennis Hyde testified that David had offered no financial support for W.L.’s medical bills;
• David had set up an online dating account at “Fet Life,” which included a listing of his (perfectly legal) sexual interests;
• Danielle testified that she had made two calls to the DHS hotline regarding W.L. and had also made two calls about Sarah’s status as a fugitive;
ha* David blocked calls from Sarah, and Danielle refused to have coffee with Sarah;
• David refused to provide the Hydes with medical documentation regarding medical treatment W.L. had received *136during one of her summer trips to Virginia;
• David lied to Dennis about their travel plans with W.L. during a winter storm, and David also told W.L. to lie to Dennis about these plans;
• During the hearing, David seemed uninterested in Sarah’s testimony, which, according to the court, was consistent with his failure to communicate with them regarding W.L.
None of these facts calls into question David’s fitness as a parent. Fitness, in this context, has an imprecise definition. In Troxel the Court suggested that a parent is fit if he or she “adequately cares for” the child. Troxel, 530 U.S. at 68, 120 S.Ct. 2054. In other cases, we have said the following: “Courts are very reluctant to take from the natural parents the custody of their child, and will not do so unless the parents have manifested such indifference to its welfare as indicates a lack of intention to discharge the duties imposed by the laws of nature and of the state to their offspring suitable to their station in life.” Lloyd v. Butts, 343 Ark. 620, 624, 37 S.W.3d 603, 606 (2001) (citing Holmes v. Coleman, 195 Ark. 196, 111 S.W.2d 474 (1937)).
At the second hearing, David addressed every concern the court had at the first hearing. Anna Hyde even testified that David had done everything the court had asked him to do at the first hearing. There were no facts to suggest that David was an unfit or improper parent. The court’s concerns do not deal with David’s ability to adequately care for W.L. or indicate an intention by David to fail to discharge his duties as a parent; instead, most related to David and Danielle’s inability or unwillingness to communicate | isand interact with the Hydes. But communication breakdowns will inevitably occur when a parents and grandparents have had protracted litigation over the custody of a young child.
Petty recriminations are unfortunately common in custody and visitation situations. For instance, David’s refusal to sit with the Hydes at W.L.’s graduation and Danielle’s refusal to have coffee with Sarah are not ideal circumstances for W.L. Neither were David’s and Danielle’s repeated but unsubstantiated reports to child-protective service agencies. These facts might be relevant in a change-of-custody situation, but they have no bearing on David’s ability to provide for W.L.’s basic needs. The clear testimony was that David was financially stable, caring, and stood ready to give her a home and provide for all of her needs.
Moreover, to deny David’s petition to terminate the guardianship would result in totally ignoring the positive steps he has taken since first consenting to the guardianship. In Devine v. Martens, we noted that courts considering guardianship cases should encourage and recognize a parent’s efforts to improve her home and parenting skills. 371 Ark. at 74, 263 S.W.3d at 526. There, the circuit court granted a guardianship petition filed by grandparents after finding that the parent was unfit. The circuit court’s unfitness finding was based on environmental neglect, educational neglect, questionable moral guidance, and abandonment. We reversed, holding that the parent had taken “significant action toward rectifying any issues that would keep her from' retaining custody of her son.” Id. | MWe noted that in guardianship cases, like dependency-neglect cases, the courts should recognize and encourage parental improvement.
Like the parent in Devine, David has taken significant steps to correct any issues that would keep him from having custody of W.L. In this case, when the first termination-of-guardianship case hap*137pened, the court refused to terminate because David had not been providing for W.L.’s material needs and lacked a significant relationship with W.L. These problems have since been rectified. David has a full-time job; he has been in a three-year, committed relationship with his new wife Danielle; and since the first hearing, he has visited Arkansas eighteen times to see W.L. and communicates with her through phone calls multiple times per week. W.L. has even spent two, six-week summer vacations with David in Virginia. Plainly stated, if the court authorizes a parent to have extended, unsupervised, and out-of-state visitation, then that provides strong evidence that the parent is fit.
Finally, consensual guardianships serve a valuable purpose. An otherwise fit parent who is struggling may recognize that, for a period of time, the child might be better off with another caregiver while the parent deals with his or her challenges. This parent should not then be punished for that foresight by making it an impossible burden to regain custody of that child. In this- case, this young, single, fit father was financially insecure and did not have medical insurance for W.L. and consented to a guardianship for his daughter’s benefit. Within one year, he stepped forward and had achieved stability in all 11firespects. He should not have had to spend five years and tens of thousands of dollars in traveling expenses before regaining custody of his daughter.
Summing up, the court clearly erred in finding that David was an unfit parent. He is a fit parent, and this court is left with a firm conviction that a mistake was made. Since David is a fit parent, the circuit court should have terminated the guardianship once David revoked his consent to it.6 Once the guardianship was terminated, the court then should have determined which parent was the proper custodian since David and Sarah had filed competing petitions for custody. It is clear that the court erred by denying David’s petition for custody of W.L. The court found Sarah. W.L.’s mother, unfit. Sarah did not appeal this or any other ruling, so this finding is law of the case. See K.S. v. State, 343 Ark. 59, 31 S.W.3d 849 (2000). A fit parent (David) should get custody of a child over an unfit parent (Sarah). We therefore reverse and remand for the court to enter an order terminating guardianship and granting custody of W.L. to David.
Reversed and remanded; court of appeals opinion vacated.
