MEMORANDUM DECISION
11 Olga Lucia Grindstaff (Wife) appeals from the trial court's orders awarding sole legal and physical custody of the parties' five children to the children's father, Robert Lee Grindstaff (Husband), excluding Wife's expert, and denying Wife's request for attorney fees. We affirm.
12 Wife does not challenge the trial court's factual findings, and therefore, we "accept the[ ] findings as true in our analysis on appeal," see d'Elia v. Rice Dev., Inc.,
13 Wife first asserts that the trial court "failed to properly analyze, weigh, and apply the statutory and common law [eusto-dy] factors," and therefore erred in awarding custody to Husband. We review custody determinations under an abuse of discretion standard, Hudema v. Carpenter,
*368
T4 Wife contends that the trial court abused its discretion because it did not give proper weight to her claim that she was the primary caretaker of the children and the fact that she was able to provide personal care for the children while Husband had to use surrogate care due to his work schedule. In making a custody determination, a trial court's primary focus is what custody arrangement would be in the best interests of the child. See Utah Code Ann. § 30-8-10(1)(a) ("In determining any form of custody, the court shall consider the best interests of the child. ..."); Cummings v. Cummings,
In support of her argument that the trial court failed to give proper weight to the fact that she was the children's primary caretaker, Wife relies on previous appellate court authority stating that "considerable weight should be given to which parent has been the child's primary caregiver," Davis,
*369
T6 We also find no error in the weight given to the fact that Wife was in the best position to provide personal rather than surrogate care after the divorcee. The record demonstrates that the trial court took that factor into consideration, expressly stating that it was "a strong argument that [Wife] should have custody." The trial court then weighed that factor against its findings that stability and remaining in the present schools and community was "important for all the children but critical for the special needs child," and that Husband was "the most likely to provide a stable, nurturing home life." (Emphasis added.) The trial court ultimately concluded that Husband should be awarded custody because the "critical" need for stability "outweighled] any negative consequences" associated with surrogate care.

Given the trial court's unchallenged finding that stability was of critical importance, we find no error in the trial court's conclusion that it would be in the children's best interest to award custody to Husband based on its conclusion that the need for stability outweighed Wife's ability to provide personal care. Cf. Hanson v. Hanson,
17 For similar reasons, we also reject Wife's contention that the trial court erred by failing to grant her joint legal custody of the children. Joint legal custody "means the sharing of the rights, privileges, duties, and powers of a parent by both parents," Utah Code Ann. § 80-83-10.1(1)(a) (2007), and many of the same factors relevant to a physical custody determination are also relevant to the question of whether joint legal custody is appropriate, see id. § 80-3-10.2@2)(c)-(d). The trial court found that only two of those factors weighed in favor of joint legal custody: the parties' equal participation in raising the children prior to the divorce and the parties' ability to encourage the children to have a positive relationship with the other parent, see id. § 30-3-10.2@)(a)-(b), (e), (@)-(J). In contrast, the trial court found that the following statutory factors-which also weighed in favor of a custody award to Husband-weighed against joint legal custody: the parties' inability to cooperate and work together on matters affecting the children, the parties "radically different ideas" about and Wife's failure to communicate with Husband regarding medical care for the child with special needs, Wife's reported abusive conduct and unwillingness to put the children's needs above her own in making decisions, and the substantial distance between the parties' homes. 7 See id. These unchallenged facts support the trial court's finding that it would have been difficult for the parties to share parenting responsibilities as required in a joint legal custody context, see id. § 80-8-10.1(1)(@). Therefore, we hold that the trial court did not exceed its discretion in concluding that joint legal custody was not in the children's 'best interest.

18 Wife next argues that the trial court abused its discretion when it found that her expert witness was unqualified and excluded the expert's testimony. "It is well established that trial courts have wide discretion in determining the admissibility of expert testimony. Consequently, absent a clear abuse of this discretion, an appellate court will not reverse the trial court's determination." State v. Kelley,
T9 Rule 702(a) of the Utah Rules of Evi-denee provides that "if scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise." Utah R. Evid. 702(a). Wife sought to introduce the testimony of her expert to rebut the findings of the custody evaluator and to testify regarding the psychological care of Wife and the parties' child with special needs. At trial, Wife's counsel conceded that the expert was not qualified to testify as a custody evaluator under the Rules of Judicial Administration, see Utah R. Jud. Admin. 4-903, which would prevent him from rebutting the custody evaluator's findings,
8
cf. Evans ex rel. Evans v. Langston,
T10 Both Wife's counsel and the expert further acknowledged that the expert's background and experience was limited to the areas of brain injury and substance abuse. Thus, although the expert had "substantial experience" in those areas, the trial court found that the expert's experience was not relevant because the expert was not qualified as a custody evaluator and there was "no indication ... that there [was] any addiction or substance abuse problem," or any "history of brain injury" in the case.
111 On appeal, Wife argues that the expert was qualified to testify because he "was prepared to [rJebut" the custody evaluator's findings and had experience with the evaluation and treatment of Wife and the parties' child with special needs. However, Wife fails to point to any aspect of the expert's "knowledge, skill, experience, training, or education," Utah R. Evid. 702(a), that would qualify him either as a custody evaluator or to testify regarding Wife's mental health or the treatment of the parties' child with special needs. Instead, Wife again cites to the expert's experience operating a brain injury clinic and his previous testimony in Nevada court cases dealing with substance abuse and addiction. As the trial court stated, none of that experience is relevant to the issues that were before the trial court in this case. Therefore, we hold that the trial court acted within its discretion in excluding Wife's expert from testifying. 9
112 Finally, we turn to Wife's argument that the trial court was required to award her reasonable attorney fees, pursuant to the attorney fees statute, see Utah Code Ann. § 80-83-38 (Supp.2010), for prevailing on the order to show cause. We generally "review a trial court's decision regarding attorney fees in a divorce proceeding for an abuse of discretion. However, the proper interpretation of a statute is a question of law," which we "review[ ] for correctness." Connell v. Connell,
1 13 The trial court gave proper weight to the relevant factors in determining that Husband should be awarded legal and physical custody of the parties' children. Because Wife's expert was not qualified as a custody evaluator or to testify regarding the issues in this case, the trial court did not exeeed its discretion when it excluded the expert's testimony. Based on its finding that Husband lacked the ability to pay, the trial court also acted within its discretion when it denied Wife's request for attorney fees related to the order to show cause. 11

{15 WE CONCUR: JAMES Z. DAVIS, Presiding Judge and STEPHEN L. ROTH, Judge.
Notes
. Wife's three older children remained in her custody, and the custody of those children is not at issue in this case.
. Because there have been no substantive changes to the relevant statutory provisions, we cite to the current version of the Utah Code as a convenience to the reader.
. Since filing her appeal, Wife has permanently moved back to Utah and she currently lives in the same community as Husband and the children. After returning to Utah, Wife sought to modify the existing custody and visitation orders. There has been no change in the custody award, but the parties stipulated to a change in the amount of Wife's parent time. The most recent order in the trial court, which supersedes the previous order, awards Wife parent time pursuant to Utah Code section 30-3-35, rather than under section 30-3-37. Thus, Wife's argument that the trial court erred in awarding her parent time less than the amount specified in section 30-3-37 is now moot because her rights under that section are no longer at issue and a ruling in "Wife's favor would not affect her rights under the order now in effect. See generally Salt Lake City v. Tax Comm'n of Utah ex rel. Mountain States Tel. & Tel. Corp.,
. Wife does not mention the trial court's finding in her opening brief but does acknowledge it in her reply brief, stating that [there is no analysis, no finding of fact[] on this prominent issue," and that, in finding that the parties were equally involved, the "[clourt might just as well have said: 'I reject your reality and substitute my own.'" Based on the established rule that "we will not consider matters raised for the first time in the reply brief," Coleman v. Stevens,
. Moreover, even if Wife had been the children's primary caretaker during the parties' marriage, that factor would not weigh as heavily in favor of Wife in this case. Indeed, we have attached lesser weight to the primary caretaker factor where giving one parent "primary physical custody will not truly preserve stability and continuity in the child's life," such as where the parent "change(s) the interpersonal dynamics of [his or] her household by remarrying and by moving from {the child's] lifelong ... home to a new home in another state." Hudema v. Carpenter,
. The trial court also found that several other factors weighed in favor of Husband receiving custody, including that Husband was emotionally "more stable," while Wife reportedly engaged in abusive conduct toward the children on two occasions and was "demonstrably less likely to place the needs of the children ahead of her own desires and needs." Other factors the trial court considered weighed equally in favor of both parties. Indeed, the trial court emphasized that it "had to make a choice between two loving and caring parents," that both parties have "great love and concern for the children," and that both parties have "much to offer the[] children." UI-timately, the trial court concluded that Husband should be awarded custody.
. In entering iis findings, the trial court explained that based upon its weighing of the statutory factors, it was rejecting the custody evaluator's recommendation that the parties should be awarded joint legal custody. Accordingly, we reject Wife's claim that the trial court failed to set forth findings regarding its deviation from the custody evaluator's report.
. In arguing that the expert was qualified to testify, counsel stated, not talking about the issues involved in a custody evaluation, we're talking about the evaluation and treatment of [the child with special needs], and evaluation of some of the clinical testing work that was done on [Wife]."
. Wife's additional argument that Husband was prevented from objecting to the expert's trial testimony by the Utah Rules of Civil Procedure is without merit. The specific section Wife referenced deals solely with the use of depositions and exhibits,.see Uiah R. Civ. P. 26(a)(4)(C), while the admissibility of expert testimony is addressed in a different section that does not require that an objection be raised before trial, see id. R. 26(a)(3)(B).
. Again, Wife does not challenge the trial court's findings, including its finding that Husband lacked the ability to pay the attorney fees, and in any event, Wife fails to marshal the evidence supporting that finding.
. To the extent that the parties raise any additional issues related to the support orders entered by the trial court, we conclude that these issues were either not preserved for appeal or were inappropriately raised in the reply brief and decline to address the merits of their arguments.
