Tree, Colorado, for Appellee and Cross-Appellant
¶1 In this post-dissolution of marriage case between Terry

Williams (father) and Amy Goscha (mother), father appeals the

order modifying decision-making responsibility for their child. He

argues that the district court erred by allocating to mother sole

decision-making authority over medical matters and international

travel. Mother cross-appeals the modification of parenting time

over Thanksgiving and winter break. We reverse the portions of the

order modifying medical decision-making responsibility and the

winter break parenting time schedule, and we remand for further

proceedings consistent with this opinion. We otherwise affirm.

I. Background

¶2 The parties were married for four years and had one child.

Upon the dissolution of their marriage, they stipulated to a

parenting plan that provided for equal parenting time and joint

decision-making responsibility for all major decisions regarding the

child. The district court approved the parenting plan.

¶3 A year and a half later, father filed a motion to modify

decision-making responsibility. He requested sole medical and

educational decision-making authority, alleging that mother was

endangering the child by refusing to allow him to be diagnosed and

1
treated for autism. Mother opposed the motion and asked the court

to “evaluate [the] ability of the parties to continue sharing decision

making, and if necessary, to allocate sole decision making to [her].”

Mother also filed a motion to modify parenting time, which among

other things, proposed modifications to holiday parenting time.

¶4 The parties filed competing proposed amended parenting

plans. Both parties requested sole decision-making responsibility

for the child’s medical care and offered differing proposals for the

division of parenting time over school holidays, including

Thanksgiving and winter break. Mother’s proposed plan also

included a provision granting her final decision-making authority as

to the propriety of any proposed international travel location.

¶5 After an evidentiary hearing, the district court allocated to

mother sole decision-making responsibility for medical matters. In

doing so, the court applied the “best interests of the child” standard

in section 14-10-124(1.5)(b), C.R.S. 2025. Noting father’s argument

that an endangerment standard should apply under section 14-10-

131(2)(c), C.R.S. 2025, the court found that “should the

endangerment standard apply, neither party has met their burden

to show that the child is endangered by the other’s decisions.” The

2
court also adopted mother’s proposed provision granting her final

decision-making authority over the location of international travel.

¶6 As to parenting time over Thanksgiving and winter break, the

court adopted a schedule that was different than the one proposed

by either party. For Thanksgiving, the parties have parenting time

from Wednesday to Friday in alternating years. For winter break,

one party has parenting time from the beginning of break until

Christmas Eve, and the other party has parenting time from

Christmas Eve until the end of break, again in alternating years.

¶7 Mother filed a post-hearing motion for reconsideration of the

Thanksgiving and winter break parenting time schedule. She

argued that the Thanksgiving schedule inadvertently modified the

parties’ existing schedule and that the winter break schedule

interfered with her extended family gathering and resulted in an

unequal division of time. The district court denied the motion.

II. Medical Decision-Making Responsibility

¶8 Father contends that the district court erred by modifying the

parties’ joint decision-making responsibility over medical matters

despite its finding that the child was not endangered. We agree.

A. Legal Standard and Standard of Review

¶9 The district court may modify a decree allocating decision-

making responsibility when the circumstances have changed and

the modification is necessary to serve the best interests of the child.

§ 14-10-131(2). But the court must retain the existing allocation

unless, as relevant here, (1) the parties agree to the modification, or

(2) the existing allocation “endanger[s] the child’s physical health or

significantly impairs the child’s emotional development and the

harm likely to be caused by a change of environment is outweighed

by the advantage of a change to the child.” § 14-10-131(2)(a), (c).

¶ 10 Thus, a district court cannot modify decision-making

responsibility based solely on the best interests of the child. In re

Marriage of Humphries, 2024 COA 92M, ¶ 22. Rather, absent an

agreement or one of the other circumstances specified in section

14-10-131, a change in decision-making responsibility requires a

finding of endangerment. Id. at ¶¶ 18, 20. This standard is “more

stringent than the best interests of the child standard.” Id. at ¶ 20.

¶ 11 The allocation of parental responsibilities lies within the sound

discretion of the district court. In re Marriage of Crouch, 2021 COA

4
3, ¶ 21. But we review de novo whether the district court applied

the correct legal standard in making its determination. Id.

B. Analysis

¶ 12 The parenting plan that the district court adopted at the time

of the dissolution decree allocated decision-making responsibility

for medical matters (and all other major decisions) to both parties

jointly. The change to sole medical decision-making by mother was

a modification of that original allocation. See In re Marriage of

Wenciker, 2022 COA 74, ¶¶ 2, 15 (applying endangerment standard

to change from joint to sole decision-making); Crouch, ¶¶ 1, 34

(same). The district court thus could not make that change without

finding one of the circumstances in section 14-10-131(2)(a)-(c).

Humphries, ¶¶ 18-20. By doing so based solely on the best

interests of the child — and with an express finding that the child

was not endangered — the district court erred. See id. at ¶¶ 20, 23.

¶ 13 In rejecting the endangerment standard, the district court

relied on In re Marriage of Stewart, 43 P.3d 740 (Colo. App. 2002),

as does mother on appeal. In Stewart, the original decree granted

the parties joint legal and physical custody, and father’s motion for

modification asked that he be named the child’s primary residential

5
parent. Id. at 741. Relying on In re Marriage of McNamara, 962

P.2d 330 (Colo. App. 1998), the division held that “where the parties

share equal parenting responsibilities, any subsequent modification

of that arrangement is governed by the best interests standard.”

Stewart, 43 P.3d at 742. It reasoned that a decree that does not

“designate a residential parent” is, “in effect, a deferral of the

custody decision,” so any change should be governed by the same

standard that would have applied at the time of the decree. Id.

¶ 14 But Stewart concerned a change to parenting time. And there

is a material difference between the statutory standards for

modification of parenting time and modification of decision-making

responsibility. Under section 14-10-129(2), C.R.S. 2025,

endangerment (or one of the other preconditions) is required for a

modification of parenting time only when the modification “changes

the party with whom the child resides a majority of the time.” See

In re Marriage of Dale, 2025 COA 29, ¶ 21 (explaining that a change

in parenting time is subject to the endangerment standard only if it

“change[s] the primary residential parent”) (cert. granted in part July

21, 2025). Because the decree in Stewart “did not designate a

residential parent,” there was no majority residential parent for the

6
court to change. 43 P.3d at 742; see also McNamara, 962 P.2d at

331 (noting that “[n]o residential parent was designated”). Thus,

the statutory endangerment standard in section 14-10-129(2)(d)

was not implicated.

¶ 15 In contrast, section 14-10-131(2) provides that any change in

the allocation of decision-making responsibility — not just a change

in a majority decision-maker — is subject to the endangerment

standard (or another precondition). Indeed, Stewart recognized this

distinction, noting that the endangerment standard generally

applies to modifications of decision-making responsibility, while the

best interests standard applies to modifications of parenting time.

43 P.3d at 742. And more recent cases have consistently applied

the endangerment standard to changes to joint decision-making.

See Wenciker, ¶¶ 2, 15; Crouch, ¶¶ 1, 34. To the extent Stewart

suggests otherwise by referring generally to a modification of “equal

parenting responsibilities,” 43 P.3d at 742, it is contrary to the

plain language of section 14-10-131(2). See Wenciker, ¶ 18 (“When

the statutory language is clear, we must enforce it as written.”).

¶ 16 We also reject mother’s contention that the joint decision-

making ordered by the original decree was not an allocation of

7
decision-making responsibility. Section 14-10-124(1.5)(b) provides

that, in determining decision-making responsibility, “the court may

allocate the decision-making responsibility with respect to each

issue affecting the child mutually between both parties or

individually to one or the other party or any combination thereof.”

Thus, an allocation of joint decision-making responsibility is just

that — an allocation — not a deferral of that decision. Cf. Stewart,

43 P.3d at 742; In re Marriage of Thomas, 2021 COA 123, ¶ 34

(“Under the old statute, even where there was an agreement for

joint decision-making, there was only one custodian . . . .”).

¶ 17 Mother also relies on cases applying a best interests standard

to the resolution of a dispute between joint decision-makers. See

Thomas, ¶ 38 (resolving dispute over school choice); In re Marriage

of Dauwe, 148 P.3d 282, 285 (Colo. App. 2006) (resolving dispute

over therapy). But there is a difference between breaking an

impasse on a particular issue and modifying decision-making

responsibility. See In re E.E.L-T., 2024 COA 12, ¶¶ 19-21; Dauwe,

148 P.3d at 285 (noting that by resolving dispute about therapy,

court did not change allocation of decision-making responsibility).

The district court in this case did not simply “break[] an impasse

8
between parents with joint decision-making responsibility.” E.E.L-T,

¶ 1. It changed the allocation of decision-making responsibility by

allocating “sole decision making over medical matters to [m]other.”

¶ 18 Finally, mother contends that, even if the heightened standard

in section 14-10-131 applies, we should nevertheless affirm

because “[t]he parties agree[d] to the modification.” § 14-10-

131(2)(a). She asserts that the parties agreed that a modification of

joint medical decision-making responsibility was necessary, even if

they disagreed as to who should be the sole decision-maker.

¶ 19 But section 14-10-131(2)(a) requires the parties to agree to the

modification, not simply a modification. See Brooks v. Zabka, 450

P.2d 653, 655 (Colo. 1969) (“[T]he definite article ‘the’ particularizes

the subject which it precedes. It is a word of limitation as opposed

to the indefinite or generalizing force of ‘a’ or ‘an.’”). The parties’

shared view that their joint medical decision-making authority

should be modified in some way — with vast disagreement about

what that modification should be — was not an agreement to the

modification the court ordered. To the contrary, father expressly

asserted that if he was not awarded sole decision-making, the

parties should continue to share joint decision-making authority.

9
¶ 20 Thus, because the district court found that the child was not

endangered by the existing allocation of joint decision-making

responsibility, it could not modify that allocation. We reverse the

portion of the order allocating sole medical decision-making

authority to mother and remand the case for the district court to

enter an order that “retain[s] the allocation of decision-making

responsibility established by the prior decree.” § 14-10-131(2).

III. International Travel

¶ 21 Father contends that our conclusion that the endangerment

standard applies to modifications of decision-making authority

means that we must also reverse the provision of the order giving

mother final decision-making authority, in the event of a dispute,

“as to whether a suggested traveling location is appropriate for [the

child].” We view the two issues differently, however, and disagree.

¶ 22 First, although mother included this provision in her proposed

parenting plan submitted before the hearing, father did not object

to it — including when the district court read the provision as part

of its oral order. And father’s proposed order submitted after the

hearing — which he asked the court to enter — also included that

provision. Father’s general opposition to mother’s request for sole

10
decision-making authority was insufficient to alert the court to his

specific objection to the international travel provision. See Crouch,

¶ 13 (noting that opposition to an adversary’s request does not

preserve all potential arguments on appeal). We do not ordinarily

address arguments not raised in the district court. Id. at ¶ 14.

¶ 23 Second, even if we were to conclude that father preserved this

argument, we are not persuaded that the international travel

provision modified the allocation of decision-making responsibility

in the original decree. The original parenting plan did not say

anything about decision-making responsibility for international

travel. Rather, its allocation of joint decision-making responsibility

was limited to “major decisions,” which it defined to include “major

medical, education, religious, and extracurricular activities.”

Father makes no argument on appeal that decisions regarding the

propriety of international travel locations fell within that provision.

¶ 24 The original parenting plan did require both parties to consent

to international travel to certain countries. But that provision

remains in the revised order. The court simply added a clause

addressing a scenario that was not addressed one way or the other

in the original plan — a dispute between the parties as to “whether

11
a suggested traveling location is appropriate.” In that specific

scenario, the court ruled that mother would have final decision-

making authority, while also ordering that mother “shall not

unreasonably deny [f]ather’s request” to travel internationally.

¶ 25 Because the original decree and parenting plan did not

allocate decision-making responsibility over the propriety of

international travel locations, the inclusion of that provision did not

modify the existing allocation. See § 14-10-131(2). And even if it

did, there was no prior allocation to retain. See id. We therefore

conclude that, even if father’s argument was preserved, the district

court did not err by adding the international travel provision based

on the best interests of the child. See id.; § 14-10-124(1.5)(b).

IV. Holiday Parenting Time

¶ 26 Mother contends that the district court abused its discretion

by adopting a new parenting time schedule for Thanksgiving and

winter break that results in an unequal allocation of the holidays.

She also asserts that the court failed to make sufficient findings to

explain the basis of its order. We perceive no abuse of discretion as

to the Thanksgiving holiday. But we agree with mother that the

12
record does not support the district court’s stated basis for its

modification of the winter break parenting time schedule.

A. Additional Background

¶ 27 The original parenting plan provided that the parties would

(1) exercise parenting time in alternate years over the Thanksgiving

holiday, from the Wednesday before Thanksgiving to the Sunday

after; and (2) split parenting time equally over the school winter

break based on a midpoint of December 27, with the parties

alternating each year whether they had the first or second half of

the break. Mother had the first half of winter break (including

Christmas) in even years, and father had the first half in odd years.

¶ 28 Both parties proposed new holiday parenting time schedules.

For Thanksgiving, mother proposed that the weeklong break be split

in half (from the child’s release from school through noon on the

Wednesday before Thanksgiving, and from noon on that Wednesday

through the child’s return to school), with the parties alternating

years. Father proposed giving one party the entire week from

Monday to Friday, again in alternating years. For winter break,

both parties favored keeping an even split. The only difference was

who had the child for which half: Mother proposed that she would

13
have her choice of halves in even years and father would have his

choice in odd years, while father proposed that he would have the

first half in even years and mother the first half in odd years.

¶ 29 The district court adopted a schedule that did not match

either party’s proposal. The court first explained that “it is in the

best interest of all parties if we don’t start messing with the

weekends any more than we have to.” It then defined Thanksgiving

as Wednesday evening to Friday evening1 and awarded the parties

parenting time in alternating years. For winter break, it split the

break with the midpoint at 5 p.m. on December 24 and ordered the

parties to alternate which part they received — with mother

receiving the first part in even years and father in odd years. The

court acknowledged that this division did not split the winter break

equally, but it explained that “the important part is Christmas Eve

and Christmas Day” and its order “addresses that as best you can.”

B. Legal Standard and Standard of Review

¶ 30 The district court may modify parenting time whenever doing

so would serve the child’s best interests. See § 14-10-129(1)(a)(I).

1 The court initially defined Thanksgiving as Wednesday evening to

Thursday evening but extended it by a day at mother’s request.

14
In making that determination, the court must consider the relevant

factors in section 14-10-124(1.5)(a). In re Custody of C.J.S., 37 P.3d

479, 482 (Colo. App. 2001). The district court need not make

findings on every factor, but its findings must be “sufficiently

explicit . . . to give the reviewing court a clear understanding of the

basis of the order.” In re Marriage of Pawelec, 2024 COA 107, ¶ 44.

¶ 31 A district court has broad discretion to modify an existing

parenting time order, and we must exercise every presumption in

favor of upholding its decision. In re Parental Responsibilities

Concerning S.Z.S., 2022 COA 105, ¶ 13. We review the parenting

time determination for an abuse of discretion, which occurs when

the decision is manifestly arbitrary, unreasonable, or unfair, or

when the court misapplied the law. Pawelec, ¶ 45. If the order is

supported by competent evidence in the record, we will not disturb

it. In re Marriage of Hatton, 160 P.3d 326, 330 (Colo. App. 2007).

C. Thanksgiving

¶ 32 The district court sufficiently explained the basis for its new

Thanksgiving parenting time schedule. Specifically, the shift from a

Wednesday-Sunday holiday to a Wednesday-Friday holiday — and

the court’s rejection of mother’s Friday-Wednesday/Wednesday-

15
Monday split — was consistent with the court’s stated desire to

avoid “messing with the weekends.” In other words, the court had

set an alternating weekend schedule and wanted to minimize the

disruption to that baseline schedule as much as possible. Further,

by limiting the Thanksgiving holiday to two days, the district court

also minimized the disruption to the regular weekday schedule.

¶ 33 Mother identifies some flaws with the court’s resolution. In

particular, she points out that since her regularly scheduled

overnights are Wednesday and Thursday, the Thanksgiving holiday

will encroach on her parenting time in father’s years. She also

explains that, in those years, father will have the child for seven

consecutive days (his normal Monday-Tuesday, Thanksgiving

Wednesday-Friday, and one of the adjacent weekends), and in her

years, the child will need to move between the parties every two

days during break (as he does under their normal schedule).

¶ 34 But in formulating the parenting time schedule, the district

court was necessarily weighing several competing considerations —

attempting to equalize parenting time, minimizing disruption and

conflict, minimizing the child’s time away from each parent, and

accommodating each party’s holiday time with the child. Indeed,

16
the change from a one-day Wednesday-Thursday holiday to a two-

day Wednesday-Friday holiday was done at mother’s request to

accommodate her family’s late afternoon Thanksgiving gathering.

Even if the schedule is not perfect, we cannot say it was manifestly

arbitrary, unreasonable or unfair. See Pawelec, ¶ 45.

D. Winter Break

¶ 35 The district court explained its decision to designate December

24 as the midpoint of winter break by saying that it wanted to avoid

a situation where one parent does not have the child on either

Christmas Eve or Christmas Day. It explained that neither the

prior parenting time order nor the parties’ proposals split the break

in a way that addressed the Christmas holiday.

¶ 36 The problem with the district court’s explanation is that

nothing in the record supports its prioritization of a Christmas

Eve/Christmas Day split over the parties’ requested equal split of

the winter break. Neither party’s proposed parenting plan

mentioned Christmas Eve (or Christmas); both parties (and the

parental responsibilities evaluator) proposed an equal division of

winter break, without regard to the holiday; and the prior plan

17
allocated Christmas and Christmas Eve both to one parent,

designating December 27 as the halfway point of the break.

¶ 37 It is true that the court was not required to adopt either

party’s proposed parenting plan. § 14-10-124(7); see also Aylor v.

Aylor, 478 P.2d 302, 304 (Colo. 1970) (“Whatever recommendations

may be made to the judge, be they by experts or counsel, they are

merely [r]ecommendations and nothing more.”). Its obligation was

to create a “practical schedule” that served the best interests of the

child. § 14-10-124(7)(b). But before adopting a winter break

parenting time schedule that neither party asked for (and that

prevented the child from attending mother’s family celebration),2 it

was incumbent on the court to ensure that its stated basis for doing

so was grounded in the record. See Hatton, 160 P.3d at 330.

¶ 38 Because there is no basis in the record for the district court’s

conclusion that “the important part [of winter break] is Christmas

2 Mother first raised the issue of her extended family’s biennial

Christmas gathering in her motion for her reconsideration. But
given the parties’ agreement on an equal split of winter break, she
had no reason to anticipate before or at the hearing that a
Christmas Eve/Christmas split was on the table. See In re Marriage
of Herold, 2021 COA 16, ¶ 7 (holding that no objection is required
to preserve an issue when the district court rules sua sponte).

18
Eve and Christmas Day,” and because the court gave no

explanation for switching mother’s Christmas parenting time from

even years to odd years, we reverse the portion of the modified

parenting time order concerning winter break. On remand, the

district court should determine a winter break parenting schedule

that is in the best interests of the child and make findings, based

on the record before it, sufficient to explain the basis of the order.

V. Disposition

¶ 39 The portions of the order modifying decision-making

responsibility over medical matters and the parenting time schedule

for winter break are reversed. The case is remanded to the district

court for further proceedings, including (1) the entry of an order

restoring the joint medical decision-making responsibility

established by the prior decree and (2) the entry of a new winter

break parenting time schedule. The order is otherwise affirmed.

JUDGE HARRIS and JUDGE JOHNSON concur.
