JUDGMENT AFFIRMED

Division IV Opinion by JUDGE BROWN Freyre and Schutz, JJ., concur

NOT PUBLISHED PURSUANT TO C.A.R. 35(e) Announced June 18, 2026

Cathleen M. Giovannini, County Attorney, Mark Olguin, Assistant County Attorney, Pagosa Springs, Colorado, for Appellee the People of the State of Colorado

Kristen Tarrin, Guardian Ad Litem

The Morgan Law Office, Kristofr P. Morgan, Colorado Springs, Colorado, for Appellant Robin Tieman, Office of Respondent Parents’ Counsel, Boulder, Colorado, for Appellee C.C. ¶1 In this dependency and neglect proceeding, T.G. (father)

appeals the judgment allocating parental responsibilities for O.G.

and V.G. (the children) between him and C.C. (mother). We affirm.

I. Background

¶2 The Archuleta County Department of Human Services filed a

petition alleging the children were dependent or neglected due to

concerns that the parents were using illegal substances. The court

adjudicated the children dependent and neglected and adopted

treatment plans for the parents.

¶3 Later, mother entered and completed an inpatient treatment

program near Grand Junction. The children were placed with her

at the treatment facility and remained in her care for the duration

of the case.

¶4 Father also entered an inpatient treatment program near

Grand Junction but did not complete it and subsequently struggled

to demonstrate sobriety. The Department had concerns about

father’s sobriety during supervised parenting time sessions.

¶5 Mother moved for an allocation of parental responsibilities

(APR), and the Department and guardian ad litem supported her

proposed APR. Father supported an APR but proposed different

1 terms for his parenting time. Following a hearing, the court largely

adopted mother’s proposal. It ordered that father may begin

therapeutic parenting time after complying with certain

requirements, including drug testing. The court permitted father to

transition to unsupervised parenting time upon providing negative

drug tests for a year, among other conditions.

II. Subject Matter Jurisdiction

¶6 Before turning to father’s contentions, we address a

“statement regarding jurisdiction” in mother’s answer brief. She

argues that the juvenile court may not have had jurisdiction to

enter an APR under the Uniform Child-custody Jurisdiction and

Enforcement Act (UCCJEA) because it did not confer with a court in

Montana where a child-custody proceeding may have been initiated.

We conclude that the court had jurisdiction to enter the APR.

A. Standard of Review and Relevant Law

¶7 The UCCJEA addresses subject matter jurisdiction, which a

party may raise for the first time on appeal. See People in Interest of

B.H., 2021 CO 39, ¶ 27. We review de novo whether the juvenile

court had subject matter jurisdiction under the UCCJEA. People in

Interest of S.A.G., 2021 CO 38, ¶ 21. We defer to a juvenile court’s

2 factual findings informing the determination of jurisdiction unless

they are clearly erroneous. Id.

¶8 “The primary aim of the UCCJEA is to prevent competing and

conflicting custody orders by courts in different jurisdictions” and

to “avoid jurisdictional competition over child-custody matters in an

increasingly mobile society.” People in Interest of M.M.V., 2020 COA

94, ¶ 17. To achieve this purpose, the UCCJEA establishes a

comprehensive framework that a Colorado court must use to

determine whether it may exercise jurisdiction in a child-custody

matter or whether it must defer to a court of another state. Id.

¶9 A court has jurisdiction to make an initial child-custody

determination if, as relevant here, that court’s state is the home

state of the child on the date of the commencement of the

proceeding. § 14-13-201(1)(a), C.R.S. 2025. “Home state” is

defined as the state in which the child lived with a parent for at

least 182 consecutive days immediately before the commencement

of the proceeding. § 14-13-102(7)(a), C.R.S. 2025.

¶ 10 A court that makes an initial child-custody determination

generally retains exclusive, continuing jurisdiction. § 14-13-202,

C.R.S. 2025; People in Interest of C.L.T., 2017 COA 119, ¶ 30. A

3 Colorado court may not modify a child-custody determination made

by a court of another state unless it has jurisdiction to make an

initial child-custody determination and (1) the court of the other

state has determined that it no longer has exclusive, continuing

jurisdiction; (2) the court of the other state has determined that the

Colorado court would be a more convenient forum; or (3) a court of

either state has determined that the child and the parents do not

presently reside in the other state. § 14-13-203(1), C.R.S. 2025;

C.L.T., ¶ 31.

B. Additional Background

¶ 11 The family resided in Montana before moving to Colorado.

While living in Colorado in April 2023, the parents co-petitioned for

an APR, and Archuleta County Case No. 23DR24 (2023 APR case)

was opened. See People v. Sa’ra, 117 P.3d 51, 56 (Colo. App. 2004)

(“A court may take judicial notice of the contents of court records in

a related proceeding.”). The following month, mother moved to

dismiss the case, asserting that she and the children had returned

to Montana. Another filing by mother on the same day was labeled

on the register of actions as “Montana Fourth Judicial District

4 Missoula County State of Montana” (Montana documents).1 See id.

The district court later dismissed the 2023 APR case.

¶ 12 Mother testified at the APR hearing in this case that she and

the children moved back to Archuleta County in September 2023.

The Department’s petition followed in late April 2024.

¶ 13 On the first day of the APR hearing, the county attorney

notified the juvenile court of the existence and procedural history of

the 2023 APR case and, in doing so, vaguely referenced the

Montana documents. But he clarified that both parents’ attorneys

reported “that there was never a domestic relations case filed in

Montana” and that Colorado was the children’s home state.

¶ 14 The court inquired of the parents’ attorneys. Mother’s counsel

agreed that Colorado was the children’s home state. When the

court specifically asked if counsel had any information about

1 Each of the Montana documents has a caption reflecting the

“State of Montana” as a plaintiff and an individual with the same name as father as a defendant. They contain titles such as “Plea Agreement” and “Affidavit of Probable Cause.” To the extent mother relies on the Montana documents to challenge jurisdiction, they do not indicate that a child-custody case was opened in Montana or that a child-custody determination issued there. See § 14-13- 102(3), (4), C.R.S. 2025; People in Interest of C.L.T., 2017 COA 119, ¶ 34. The Montana documents clearly involve a criminal proceeding.
