Child Custody in Colorado: Laws and Factors

A mother in Denver assumed she would automatically receive primary custody of her two children after filing for divorce. Her attorney explained that Colorado does not use the word “custody” in its family law statutes — and that there is no presumption favoring mothers. At the hearing, the court examined each parent’s history of involvement with the children, their work schedules, and their willingness to support the other parent’s relationship. The judge allocated equal parenting time and joint decision-making responsibility, citing the father’s consistent involvement in school activities, medical appointments, and daily caregiving.

Colorado’s approach to what other states call custody is built on a different philosophy. Rather than awarding one parent “custody” and the other “visitation,” Colorado allocates parental responsibilities between both parents. The framework treats post-separation parenting as a shared obligation, and the court’s only standard is what serves the child’s best interests.

This guide covers Colorado custody law as it works in 2026: the allocation of parental responsibilities, the statutory best interest factors, parenting time and decision-making, mediation and professional evaluations, domestic violence protections, modification standards, relocation rules, and custody for unmarried parents. For a national overview of custody law, see our guide on child custody laws explained.

How Colorado Defines “Custody”

Colorado eliminated the terms “custody” and “visitation” from its family law statutes. Under C.R.S. Section 14-10-124, what other states call custody is known as the allocation of parental responsibilities (APR). This is not just a language change — it reflects the state’s policy that both parents share responsibilities for their children after separation.

The framework divides parental responsibilities into two independently allocated components: decision-making responsibility and parenting time. The court allocates each one separately based on the child’s best interests, meaning a parent can have equal parenting time but sole decision-making authority, or vice versa.

Decision-Making Responsibility

Decision-making responsibility covers major life decisions for the child in four areas:

• Education — school enrollment, special education services, tutoring, and related choices
• Healthcare — medical, dental, and mental health treatment decisions
• Religion — religious instruction, participation, and upbringing
• Extracurricular activities — organized sports, lessons, camps, and clubs

Day-to-day decisions — meals, homework, bedtime, discipline — are made by whichever parent has the child at the time. These are not part of the decision-making allocation.

Joint Decision-Making

Joint decision-making means both parents must agree on major decisions in the allocated areas. Colorado courts generally favor joint decision-making when the parents can cooperate. Under C.R.S. Section 14-10-124(1.3), the court considers the parents’ ability to cooperate, their history of involvement in decision-making, and whether mutual decision-making has been workable.

If joint parents disagree on a major decision, the parenting plan should include a dispute resolution process — typically mediation — before either parent returns to court.

Sole Decision-Making

Courts award sole decision-making when the evidence shows that joint decision-making is not feasible. Common reasons include a history of domestic violence, a demonstrated inability to cooperate on basic decisions, one parent undermining the other’s involvement, or geographic distance that makes consultation impractical.

The court can also split decision-making by category — for example, one parent might have sole authority over education while both parents share healthcare decisions jointly. This allows the court to tailor the allocation to the family’s specific dynamics.

Parenting Time

Parenting time determines the physical schedule — when each parent has the child in their care. This replaces what other states call “physical custody” or “visitation.”

Colorado has no statutory presumption in favor of equal parenting time. The court evaluates each family’s circumstances individually under the best interest factors. However, Colorado law does express a policy favoring frequent and continuing contact with both parents, and 50/50 arrangements are common when circumstances support them.

Common Parenting Time Schedules

Colorado courts tailor parenting time to each family, but certain schedules appear frequently:

Equal parenting time schedules (for parents who live close enough):

• Alternating weeks — the child spends one full week with each parent
• 2-2-3 rotation — the child alternates between parents every two or three days, resulting in equal time over a two-week cycle
• 5-2-2-5 — the child spends five days with one parent, two with the other, then reverses

Schedules when one parent has more time:

• Every other weekend plus midweek — one parent has every other weekend (Friday to Sunday) and one midweek overnight
• 1st, 3rd, and 5th weekends — one parent has the child on these weekends plus a midweek evening
• Extended summer time — the parent with less regular time receives additional consecutive weeks during summer break

Holiday and vacation time is typically alternated annually or split between parents. A well-drafted parenting plan specifies exact pickup and drop-off times for every holiday to minimize future conflict.

Best Interest Factors

Under C.R.S. Section 14-10-124(1.5), Colorado courts evaluate the following factors when determining parenting time:

The Wishes of the Parents

The court considers what each parent wants regarding the parenting time schedule. However, the parents’ preferences are just one factor — the court is not bound by either parent’s proposed plan.

The Wishes of the Child

If the child is sufficiently mature to express reasoned and independent preferences, the court may consider the child’s wishes regarding the parenting time schedule. Colorado does not set a specific age at which a child can express a preference. In practice, older teenagers’ views carry more weight, but even then, the child’s wishes are one factor among many — the child does not get to “choose.”

The court may hear the child’s preference through an in-chambers interview, a child and family investigator (CFI), or a parental responsibilities evaluator (PRE).

Relationships and Interactions

The court examines the child’s interaction and interrelationship with each parent, siblings, and any other person who significantly affects the child’s best interests. Strong bonds with extended family members, step-siblings, or other household members are relevant.

Adjustment to Home, School, and Community

The child’s current adjustment to home, school, and community weighs in the analysis. A child who is thriving academically, has established friendships, and participates in extracurricular activities at one location may be harmed by a disruption to that stability.

Mental and Physical Health

The mental and physical health of all individuals involved is relevant. However, a parent’s disability alone cannot be a basis for denying or restricting parenting time — the court focuses on how any health condition specifically affects the parent’s ability to care for the child.

Willingness to Support the Other Parent

The court evaluates each parent’s ability to encourage the sharing of love, affection, and contact between the child and the other parent. This is sometimes called the “friendly parent” factor, and it can be influential in close cases. A parent who denies parenting time without justification, speaks negatively about the other parent in front of the children, or undermines the other parent’s relationship is viewed unfavorably.

However, Colorado law explicitly provides that actions taken to protect a child from witnessing or suffering abuse shall not count against a parent under this factor.

Past Pattern of Involvement

The court considers whether each parent’s past pattern of involvement with the child reflects a system of values, time commitment, and mutual support. Who handled school pickups, medical appointments, homework help, bedtime routines, and daily caregiving matters significantly.

Ability to Prioritize the Child

Each parent’s ability to place the child’s needs ahead of their own is evaluated. A parent who demonstrates flexibility, cooperativeness, and child-focused decision-making is viewed more favorably than one who prioritizes personal convenience or uses the child as leverage.

Physical Proximity

The physical proximity of the parents to each other affects the practical considerations of parenting time. Parents who live close together can more easily share equal time and handle midweek transitions. Greater distance may require a different schedule structure.

Mediation

Mediation is mandatory in many Colorado counties before a contested parental responsibilities case can proceed to trial. Under C.R.S. Section 14-10-128.5, the court may order mediation in any case involving allocation of parental responsibilities, and many judicial districts have local rules making mediation a required step.

Mediation gives parents the opportunity to negotiate a parenting plan with the help of a neutral third party. Agreements reached through mediation tend to be more durable because both parents have a stake in the outcome. If mediation does not result in an agreement, the case proceeds to a hearing where the court allocates responsibilities.

Mediation is typically not ordered in cases involving domestic violence unless appropriate safety measures are in place. A parent who has been the victim of domestic violence can request that the court waive the mediation requirement.

The CFI and PRE

In contested cases, the court may appoint a professional to investigate and make recommendations. Colorado uses two types of evaluators under C.R.S. Section 14-10-123.4.

Child and Family Investigator (CFI)

A CFI conducts a focused investigation into the disputed custody issues. The CFI interviews both parents, may interview the children, contacts relevant third parties (teachers, counselors, doctors), and submits a written report with recommendations to the court. The CFI’s fees are capped at $2,750 by statute, and both parents typically share the cost.

A CFI is appropriate for cases where the disputes are relatively straightforward — disagreements about the parenting time schedule, decision-making allocation, or specific parenting concerns.

Parental Responsibilities Evaluator (PRE)

A PRE conducts a more thorough evaluation than a CFI. A PRE is qualified to perform psychological testing, conducts extensive home visits, observes parent-child interactions, and produces a more detailed report. There is no statutory fee cap for a PRE, and costs can run significantly higher than a CFI.

A PRE is typically reserved for high-conflict cases involving allegations of mental health issues, substance abuse, domestic violence, or parental alienation. The court may adjust the cost allocation between parents based on ability to pay.

Both the CFI and PRE serve as the investigative arm of the court. Their recommendations are influential but not binding — the judge makes the final decision.

Domestic Violence and Parental Responsibilities

Colorado takes domestic violence seriously in custody cases. Under C.R.S. Section 14-10-124(4), there is a statutory presumption against allocating sole or joint decision-making responsibility to a parent who has committed domestic violence. The abusive parent bears the burden of overcoming this presumption by demonstrating that decision-making authority would serve the child’s best interests.

This presumption applies even if the violence was directed at the other parent rather than the child. The law recognizes that witnessing domestic violence harms children and that an abusive partner may not exercise sound judgment in major decisions affecting the child.

Impact on Parenting Time

The domestic violence presumption applies specifically to decision-making responsibility. The court may still allocate parenting time to a parent who committed domestic violence, but it may impose conditions:

• Supervised parenting time — visits occur in the presence of a professional supervisor or approved third party
• Treatment requirements — completion of a domestic violence treatment program, substance abuse counseling, or anger management
• Restrictions on overnights — limited or no overnight parenting time until conditions are met
• Safety provisions — neutral exchange locations, no-contact orders during transitions

If the court orders unsupervised parenting time despite domestic violence allegations, the judge must make a written or oral statement explaining why unsupervised time is in the child’s best interests, with paramount consideration given to the child’s safety.

Custody for Unmarried Parents

When parents are not married, Colorado law treats custody rights differently until paternity is established.

The Mother’s Rights

An unmarried mother has automatic legal custody of a child born outside of marriage. She has sole decision-making authority and full parenting time rights without needing a court order.

The Father’s Rights

An unmarried father does not automatically have custody or parenting time rights, even if his name appears on the birth certificate. To gain legal rights, the father must establish paternity through one of the following methods:

• Voluntary Acknowledgment of Paternity — both parents sign an acknowledgment form, typically at the hospital after birth
• Court-ordered paternity determination — the father files a parentage action, and the court may order genetic testing. Under C.R.S. Section 19-4-105, if testing shows a probability of genetic parentage of 97% or higher, the father is presumed to be the natural parent

After Paternity Is Established

Once paternity is legally established, the father has equal standing to seek an allocation of parental responsibilities. The court applies the same best interest factors it would in any custody case. The father also takes on an equal obligation to provide financial support for the child.

For more on this topic, see our guide on custody for unmarried parents.

Modifying an Existing Order

Colorado imposes strict standards for modifying an existing allocation of parental responsibilities. The standard depends on what is being modified and how much time has passed.

Modifying Decision-Making (C.R.S. Section 14-10-131)

To modify decision-making responsibility, the requesting parent must show that a change serves the child’s best interests based on facts that have arisen since the prior order or were unknown at the time. Additionally, the retention of the current allocation would endanger the child’s physical health or significantly impair emotional development, or the harm likely caused by a change of environment is outweighed by the advantage of the change.

The Two-Year Bar

Under C.R.S. Section 14-10-131(2), if a motion for modification has been filed — whether or not it was granted — no subsequent motion may be filed within two years unless the court finds reason to believe that the current arrangement endangers the child’s physical health or significantly impairs emotional development. This is one of the strictest modification thresholds in the country.

Modifying Parenting Time (C.R.S. Section 14-10-129)

Modification of parenting time requires a showing that it is in the best interests of the child based on a change of circumstances. The standard for modifying parenting time is generally less strict than for modifying decision-making responsibility, but the requesting parent must still demonstrate that circumstances have materially changed since the original order.

Relocation

Colorado has specific relocation provisions under C.R.S. Section 14-10-129. A relocation does not have to be out of state — any move that substantially changes the geographical ties between the child and the other parent triggers the relocation rules.

Notice Requirements

The relocating parent must provide written notice to the other parent as soon as practicable. The notice must include the proposed new location, the reason for the relocation, and a proposed revised parenting time schedule.

If the Other Parent Objects

If the non-relocating parent objects, the court holds a hearing. Relocation cases receive priority on the court’s docket. The court evaluates the proposed move under the best interest factors, considering:

• The reasons for the proposed relocation and the reasons for the other parent’s objection
• The quality of the child’s relationship with each parent and siblings
• Educational opportunities at the current and proposed locations
• The presence of extended family or support networks in either location
• The advantages of the child remaining with the primary caregiver
• Whether a revised parenting time schedule can preserve the child’s relationship with both parents
• Any other relevant factors

If the court permits the relocation, it modifies the parenting plan to account for the distance — typically increasing the non-relocating parent’s summer, holiday, and school break time.

The Parenting Plan

Colorado requires parents to submit a parenting plan as part of every allocation of parental responsibilities case. A complete Colorado parenting plan must address:

• Decision-making allocation — which parent has authority in each area, or whether it is joint
• Parenting time schedule — regular weekdays and weekends, holidays, school breaks, summer, and special occasions
• Transportation — who provides transportation for exchanges and where they occur
• Dispute resolution — how parents will handle disagreements before returning to court (typically mediation)
• Communication — how each parent will communicate with the child during the other parent’s time
• Relocation notice — requirements if one parent intends to move

When parents agree, they submit a joint parenting plan. When they cannot agree, each parent may submit a separate proposed plan, and the court will fashion an arrangement based on the evidence and the best interest factors.

What to Do Next

If you are facing an allocation of parental responsibilities case in Colorado, take these steps:

1. Learn the terminology. Colorado courts use “parental responsibilities,” “decision-making responsibility,” and “parenting time” — not “custody” and “visitation.” Using the correct terms signals familiarity with the process.
2. Document your caregiving history. The court examines each parent’s past pattern of involvement. Keep records of school pickups, medical appointments, extracurricular activities, homework help, and daily caregiving tasks.
3. Prepare a detailed parenting plan. Include exact days and times, holiday rotations, a realistic transportation arrangement, and a dispute resolution mechanism.
4. Demonstrate willingness to cooperate. The “friendly parent” factor is significant in Colorado. Show that you support the child’s relationship with the other parent through your actions and communication.
5. Be prepared for a CFI or PRE. In contested cases, the court will likely appoint an investigator. Cooperate fully and focus on demonstrating your involvement in your child’s life.
6. Consult a Colorado family law attorney. The allocation of parental responsibilities is complex and fact-intensive. Schedule a consultation with an attorney who regularly handles these cases in your county.

Frequently Asked Questions

Is Colorado a 50/50 custody state?

Colorado does not have a statutory presumption for equal parenting time. Each case is evaluated individually under the best interest factors in C.R.S. Section 14-10-124. However, Colorado law favors frequent and continuing contact with both parents, and 50/50 arrangements are common when circumstances support them — particularly when parents live close to each other and both have been actively involved in caregiving.

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

Colorado does not set a specific age at which a child can choose. The statute allows the court to consider the child’s wishes if the child is “sufficiently mature to express reasoned and independent preferences.” In practice, older teenagers’ preferences carry more weight, but the child’s wishes are always just one factor among many. The court evaluates whether the preference is genuine, well-reasoned, and not the product of coaching.

What rights does an unmarried father have to custody in Colorado?

An unmarried father does not automatically have custody or parenting time rights, even if his name is on the birth certificate. He must first establish paternity — either through a Voluntary Acknowledgment of Paternity or a court-ordered paternity determination with genetic testing. Once paternity is established, the father has equal legal standing to seek an allocation of parental responsibilities, and the court applies the same best interest factors as in any other case.

How long does a custody case take in Colorado?

If parents reach agreement through negotiation or mediation, a parenting plan can be finalized within two to four months. Contested cases that require a CFI or PRE investigation and trial typically take 6 to 12 months. Cases involving domestic violence, relocation disputes, or complex financial issues may take longer. Many Colorado counties require mandatory mediation before trial, which can add time but often results in settlement.

What is the difference between a CFI and a PRE in Colorado?

A child and family investigator (CFI) conducts a shorter, focused investigation with fees capped at $2,750. A parental responsibilities evaluator (PRE) conducts a more thorough evaluation — including psychological testing and home visits — with no statutory fee cap. A PRE is typically reserved for high-conflict cases. Both investigate the family situation and make recommendations to the court, and both parents usually share the cost.

Can I move out of state with my child in Colorado?

Not without either the other parent’s consent or court approval. Under C.R.S. Section 14-10-129, any move that substantially changes the geographical ties between the child and the other parent requires written notice and, if the other parent objects, a court hearing. Moving without proper notice can result in serious legal consequences, including modification of parenting time in favor of the non-relocating parent.
