Colorado Child Custody Laws (2026): Parental Responsibilities, Best Interests, and Your Rights

Colorado courts decide parental responsibilities, which cover both decision-making authority and parenting time, based solely on the best interests of the child under Colorado Revised Statutes Section 14-10-124. Colorado dropped the word "custody" in 1999 and has no presumption of equal parenting time.

How does Colorado decide parental responsibilities?

Colorado courts allocate parental responsibilities, the state's term for what most people call custody, under the best interests of the child standard established in Colorado Revised Statutes Section 14-10-124. The statute directs courts to give paramount weight to the safety and physical, mental, and emotional health of the child. Cases are heard in the district court (domestic relations division). Under CRS 14-10-123(1)(a)(II), a parent commences a parental-responsibilities case by filing a petition in the county where the child is permanently resident or where the child is found; there is no county-level requirement that the child have lived there for any set period. A separate, state-level rule decides whether Colorado rather than another state may hear the case at all: under Colorado's Uniform Child-custody Jurisdiction and Enforcement Act, the child's "home state" is the state where the child lived with a parent for at least 182 consecutive days immediately before the case was filed (CRS 14-13-102(7)(a)).

Colorado law requires the court to make two separate determinations: how decision-making responsibility will be allocated between the parents, and what the parenting-time schedule will be. These two questions use overlapping but distinct factor lists, both contained in CRS 14-10-124. Colorado updated this statute in 2021 and 2024 to add explicit coercive-control and domestic-violence provisions, reflecting legislative concern that abusive dynamics were underweighted in the prior framework.

Types of parental responsibilities in Colorado

Because Colorado law uses specific terminology, understanding the vocabulary is essential.

Decision-making responsibility is what other states call legal custody. It is the authority to make major decisions for the child: education, healthcare, religion, and extracurricular activities. Courts may allocate decision-making jointly (both parents must agree on major decisions) or solely (one parent decides). If joint decision-making is ordered, the parenting plan must include a dispute-resolution process for when the parents disagree.

Parenting time is what other states call physical custody or visitation. It is the schedule defining when the child is with each parent. Courts can designate one parent as the "primary residential parent" or can divide time in roughly equal blocks, depending on what the evidence shows is best for the child. There is no presumption in favor of any particular schedule.

Both forms of parental responsibility can be modified independently, and they are governed by separate statutes: parenting time by CRS 14-10-129 and decision-making responsibility by CRS 14-10-131. The threshold also differs depending on whether you are seeking to change the majority-time parent or only adjust the schedule.

Does Colorado presume equal parenting time?

No. Colorado has no statutory presumption of equal parenting time. This is one of the most frequently misunderstood points about Colorado family law. While some parents reach agreements that are close to equal, the court starts with no thumb on the scale. Every case is analyzed individually under the best-interests factors.

Colorado's legislature has considered equal-parenting-time presumption bills several times. The most recent attempt was SB26-027 (2026), the "Parental Equality & Child Empowerment Act," which would have created a rebuttable presumption of equal parenting time where both parents live within 25 miles of a court-determined location, rebuttable only by clear and convincing evidence. The Senate Committee on State, Veterans, & Military Affairs postponed the bill indefinitely on February 3, 2026, by a 3-2 vote, so it did not pass. Because no equal-time presumption has ever been enacted, no Colorado decision has created one either; courts simply apply the best-interests factors in CRS 14-10-124 to the facts of each case. In practice, many Colorado judges do land on schedules at or near equal time when the evidence supports it, but that is the result of the factor analysis, not a starting presumption.

What Colorado does have is a strong policy against contact restrictions that are not justified by the evidence. Courts expect both parents to facilitate and encourage a relationship between the child and the other parent; a parent who unreasonably blocks contact risks having that weighed against them in the best-interests analysis.

Parents comparing schedule options in a Colorado case can use the parenting-time calculator to turn a proposed overnight count into a percentage.

The best interests factors Colorado courts weigh

CRS 14-10-124 sets out separate factor lists for parenting time and for decision-making. The parenting-time factors include:

• The wishes of the child's parents as to parenting time
• The child's wishes, if the child has sufficient maturity to express a preference
• The interaction and interrelationship of the child with parents, siblings, and others who significantly affect the child's best interests
• The child's adjustment to home, school, and community
• The mental and physical health of all individuals involved
• The ability of each parent to encourage the sharing of love, affection, and contact between the child and the other parent
• Whether the past pattern of involvement of each parent reflects a system of values, time commitment, and mutual support
• The physical proximity of the parties to each other as it relates to the practical considerations of parenting time
• The ability of each party to place the child's needs ahead of his or her own needs

For decision-making responsibility, the statute adds cooperation-focused factors: whether the parents are able to make decisions jointly, whether prior attempts at joint decision-making have functioned, and the level of conflict between the parents.

Courts also weigh domestic violence and child abuse history. The 2021 and 2024 amendments added coercive control as an explicit consideration, recognizing that ongoing psychological control can harm children even in the absence of physical violence.

Relocation: moving with your child in Colorado

Colorado Revised Statutes Section 14-10-129 governs relocation. A parent who intends to relocate with the child to a place that substantially changes the child's geographic proximity to the other parent must provide written notice as soon as practicable. The notice must include the location of the new residence, the reason for the proposed relocation, and a proposed revised parenting-time schedule.

After receiving notice, the other parent may object and request a hearing. Colorado courts prioritize relocation hearings because the proposed move date often cannot be delayed indefinitely. At the hearing, the court applies a best-interests analysis that specifically includes statutory relocation factors: the reasons for the move; the reasons the other parent objects; the history and quality of each parent's relationship with the child; the educational opportunities available at each location; the presence of extended family; any advantages the move offers the child; and the anticipated impact on the child's relationship with the nonrelocating parent.

Relocation is one of the circumstances CRS 14-10-129(2)(c) identifies as a basis for departing from the parenting-time schedule in the prior decree, which means a proposed move can trigger a full review of the existing parenting plan.

Changing a parental responsibilities order in Colorado

Colorado splits modification between two separate statutes. CRS 14-10-129 governs modification of parenting time, and CRS 14-10-131 governs modification of decision-making responsibility, which is what other states call legal custody. The key requirements vary depending on which of the two you are asking the court to change.

To change which parent has the majority of parenting time, CRS 14-10-129(2) requires the court to find, on the basis of facts that have arisen since the prior decree or that were unknown to the court at the time of the prior decree, that a change has occurred in the circumstances of the child or the majority-time parent, and that the modification is necessary to serve the child's best interests. CRS 14-10-131(2) applies the same two-part test to a change in decision-making responsibility.

Note what those statutes do not say. Neither requires a "substantial and continuing" change in circumstances. That heavier phrase is the standard for modifying maintenance and child support elsewhere in Title 14, and within CRS 14-10-129 it appears only in the narrow subsection (2.5)(a) route available to a parent whose parenting time the court had previously restricted. What both modification statutes do require is that the change rest on facts arising after the prior decree or unknown to the court when it entered.

To modify the parenting-time schedule without changing the majority-time parent, the threshold is a showing that the proposed change serves the child's best interests, though a change in circumstances still informs the analysis.

Colorado also imposes a temporal limit on repeat motions, and each statute carries its own version. Under CRS 14-10-129(1.5), once a motion that would substantially modify parenting time and also change which parent the child lives with a majority of the time has been filed and decided, no subsequent motion of that kind may be filed within two years unless the court decides, on the basis of affidavits, that the child's present environment may endanger the child's physical health or significantly impair emotional development, or that the majority-time parent intends to relocate in a way that substantially changes the child's geographic ties to the other parent.

CRS 14-10-131(1) imposes a parallel two-year bar on repeat motions to modify decision-making responsibility, lifted only if the court decides on the basis of affidavits that there is reason to believe continuing the prior order may endanger the child's physical health or significantly impair emotional development. These bars are intended to protect children from repeated and disruptive litigation; neither limits motions that only adjust the parenting-time schedule without changing the majority-time parent. After two years have passed, the ordinary change-in-circumstances and best-interests analysis applies.

If you are facing a parental responsibilities case in Colorado

Whether you are filing for divorce, establishing parentage, or seeking to modify an existing order, these practical steps can improve your outcome.

Draft a parenting plan from day one. Colorado courts strongly prefer that parents arrive with a proposed plan. A thoughtful, child-focused plan demonstrates good faith and gives the court a starting point.

Document your involvement. Keep records of school pickups, medical appointments, daily caregiving, and communications with the other parent. The history-of-past-involvement factor in CRS 14-10-124 rewards the parent who has been consistently present.

Address safety concerns directly. If domestic violence or coercive control is a factor, Colorado's 2021 and 2024 statutory amendments provide an explicit framework for raising those issues. Courts take these allegations seriously when supported by evidence.

Use mediation. Colorado district courts require parents to participate in dispute-resolution processes before contested hearings in most counties. Private mediation through a certified mediator is also available and often results in more flexible, durable agreements.

Consult a Colorado family-law attorney. Colorado's parental-responsibilities statute is detailed and the factor analysis is genuinely fact-specific. A licensed family-law attorney familiar with your district's judges can advise you on how local courts typically weigh specific factors and help you prepare for hearings.

Frequently Asked Questions

How is child custody determined in Colorado?

Colorado does not use the word custody. It allocates 'parental responsibilities,' which cover both decision-making and parenting time, under the best interests of the child standard in CRS 14-10-124. The court weighs the child's safety, health, adjustment to home and school, each parent's history of involvement, the ability to encourage a relationship with the other parent, and other statutory factors.

Does Colorado favor the mother in parental responsibilities cases?

No. Colorado law is gender-neutral. The tender-years doctrine, which historically favored mothers of young children, has been abolished. CRS 14-10-124 does not permit any preference based on the sex of a parent or child. Both parents begin on equal legal footing.

Is Colorado a 50/50 custody state?

No. Colorado has no presumption of equal parenting time. Bills to create such a presumption have been considered several times, most recently SB26-027 (2026), a proposed rebuttable presumption of equal parenting time for parents living within 25 miles of a court-determined location; the Senate postponed it indefinitely on February 3, 2026. Courts analyze each family's facts under CRS 14-10-124 without a default schedule. Equal parenting time is possible when the evidence supports it, but it is not the starting point.

At what age can a child choose which parent to live with in Colorado?

Colorado has no fixed age at which a child's preference controls the outcome. CRS 14-10-124 requires courts to consider the child's wishes when the child has sufficient maturity to express a reasoned preference. In practice, Colorado courts give more weight to the views of teenagers than to young children, but the judge retains the authority to decide.

How do I change a parenting time order in Colorado?

It depends on what you are changing. A schedule adjustment that does not change which parent the child lives with most of the time is decided on the child's best interests under CRS 14-10-129(1)(a)(I). If your motion would change the majority-time parent, CRS 14-10-129(2) requires a showing, based on facts that have arisen since the prior decree or that were unknown to the court at that time, that a change has occurred in the circumstances and that the modification is necessary to serve the child's best interests. The statute does not require a 'substantial and continuing' change. A motion of that kind also triggers a two-year bar on re-filing under CRS 14-10-129(1.5), unless the child's present environment may endanger their physical health or impair emotional development, or the majority-time parent intends to relocate in a way that substantially changes the child's geographic ties to the other parent. Changing decision-making responsibility is governed separately, by CRS 14-10-131.

Can a parent move away with the child in Colorado?

A Colorado parent who plans to relocate with the child to a place that substantially changes the child's proximity to the other parent must provide written notice as soon as practicable under CRS 14-10-129. The notice must include the new address, the reason for the move, and a proposed revised parenting-time schedule. The other parent may object and request a hearing, where the court applies a best-interests analysis using specific relocation factors.

What is the difference between decision-making responsibility and parenting time in Colorado?

Decision-making responsibility (Colorado's term for legal custody) is the authority to make major decisions about the child's education, healthcare, religion, and activities. Parenting time (Colorado's term for physical custody) is the schedule defining when the child is with each parent. Colorado courts decide these two issues separately, using related but distinct statutory factor lists under CRS 14-10-124.
