Colorado Child Custody Laws: Parenting Plans, Jurisdiction, and Modifications

Colorado child custody laws don’t actually use the word “custody.” The state calls it the Allocation of Parental Responsibilities, and it splits what most people think of as custody into two separate decisions: who makes major decisions for the child, and how parenting time is divided. Both are decided by a judge under the best interests of the child standard in C.R.S. § 14-10-124.¹ The process has specific forms, filing fees, deadlines inside the first 42 days, and standards that get much harder to meet once an order is in place.

How Judges Decide What’s in the Child’s Best Interests

Every custody decision in Colorado turns on one question: what arrangement best serves the child? The statute puts the child’s safety and physical, mental, and emotional needs above everything else.¹ Beyond safety, judges weigh the wishes of each parent, the child’s relationships with parents and siblings, and how settled the child is in their current home, school, and community.

Judges also look at whether each parent can encourage a healthy relationship between the child and the other parent. A parent who undermines that bond, or who makes unilateral decisions without consulting the other, will face scrutiny. Past involvement in day-to-day parenting matters. So does the physical and mental health of everyone in the household. Any history of domestic violence or child abuse carries heavy weight and can reshape the outcome entirely. If the court orders unsupervised parenting time despite an accusation involving domestic violence, child abuse, or child sexual abuse, the judge must put on the record why unsupervised contact serves the child’s best interests.

Decision-Making Authority and Parenting Time Are Separate

Decision-making authority is the legal right to make major choices about education, healthcare, religious upbringing, and extracurricular activities. There is no presumption in Colorado favoring joint decision-making. Judges can allocate these responsibilities jointly, solely to one parent, or in any mix. A court might give one parent sole authority over medical decisions, for example, while requiring joint agreement on schooling. When parents cannot communicate on basic issues, or when there is credible evidence of domestic violence or abuse, sole authority to one parent becomes far more likely.

Parenting time is the physical schedule — when the child actually lives with each parent. Colorado uses a specific overnight threshold to classify arrangements. When each parent has at least 93 overnights per year, the arrangement qualifies as shared physical care. If one parent has fewer than 93 overnights (the other has 273 or more), it’s sole physical care, and the majority-overnight parent is the primary residential parent.² That 93-night line matters because it changes how child support is calculated under the state’s income shares model.

These two allocations are independent of each other. A parent with limited overnights can still hold joint decision-making authority, and a parent with the majority of overnights can still be denied sole decision-making power. Schedules themselves depend on the child’s age and development, the parents’ work schedules, the distance between homes, and the child’s school location. Infants and toddlers often do better with shorter, more frequent visits; older children may follow an alternating-week or 5-2-2-5 rotation.

What Your Parenting Plan Has to Cover

Colorado requires parents to submit a parenting plan whenever parental responsibilities are allocated. If neither parent submits one, or if the court rejects what’s submitted, the judge writes it. The standard form is JDF 1113, and it covers more ground than most parents expect.³

Decision-making allocation across education, medical and dental care, mental health, religious activities, extracurriculars, and passport authorization.
School-year schedule with specific weekday and weekend arrangements, including transportation for exchanges.
Summer schedule, either as a separate plan or a statement that the school-year schedule continues.
Holidays and special occasions — school breaks, cultural and religious holidays, state holidays, and birthdays. This schedule overrides the regular rotation when they conflict.
Total overnights per year for each parent out of 365.
Travel and communication rules, including notification for overnight and out-of-state travel and phone access during the child’s waking hours.
Child support amount, frequency, start date, and payment method.
Health insurance responsibility and how extraordinary medical costs are split.
Which parent claims the children as tax dependents.
A dispute resolution process, such as mediation or arbitration.

Optional costs like private school tuition and extracurricular expenses can also go in the plan. Courts favor plans that are as specific as possible, particularly when parenting time is contested. Vague clauses lead to repeat trips to court.

Right of First Refusal

Some plans include a right of first refusal: the parent whose scheduled time it is must offer that time to the other parent before arranging outside childcare. This clause isn’t automatic in Colorado. It applies only if the parenting plan includes it, and only works in practice if it spells out the minimum absence that triggers the obligation, how quickly the other parent must respond, and who handles transportation.

Jurisdiction: The 182-Day Rule

Before a Colorado court can decide anything, it needs jurisdiction. Under the state’s version of the Uniform Child-Custody Jurisdiction and Enforcement Act, the child must have lived in Colorado for at least 182 consecutive days before the case is filed. If the child recently left Colorado but a parent still lives here, Colorado can keep home-state jurisdiction for 182 days after departure.⁴ If your child doesn’t meet the threshold, the case likely belongs in whichever state does qualify as the home state.

Filing the Case

If custody isn’t tied to a divorce, you file a Petition for Allocation of Parental Responsibilities on JDF 1413. If it’s part of a divorce, you use the Petition for Dissolution of Marriage (JDF 1000) with a Case Information Sheet.⁵ Both require the child’s residence history for the past five years — every address, every person the child lived with, and the relationship — along with current contact information for both parents.

You file with the clerk of the district court in the county where the child lives. The standalone custody petition fee is $252. If custody is part of a divorce, the fee is $260.⁶ Fee waivers are available for parents who can’t afford it.

Deadlines in the First 42 Days

After filing, the other parent must be formally served by a disinterested third party or professional process server. The responding parent then has 21 days to file a response if served inside Colorado, or 35 days if served outside the state.⁷

An initial status conference must take place no later than 42 days after the petition is filed.⁸ That conference sets the timeline, identifies contested issues, and determines whether mediation is needed. Showing up unprepared sets a bad tone for the rest of the case.

Within 40 days of being served, both parents must exchange a set of mandatory financial documents under Rule 16.2 — a Sworn Financial Statement, supporting schedules, and the mandatory disclosure form. No one has to formally request these; the rule requires the exchange automatically. The sworn financial statement and supporting schedules are filed with the court; the rest is exchanged between parties. Having everything ready by the initial status conference is the practical target.

Courts can also order both parents to attend a parenting education program covering the impact of separation on children and strategies for cooperative co-parenting.⁹ The statute says “may,” but most judicial districts treat it as standard. Approved Colorado providers generally charge somewhere between $20 and $135 depending on the program.¹⁰

When a Child and Family Investigator Gets Involved

In contested cases, the court can appoint a Child and Family Investigator (CFI) — a neutral third party whose job is to investigate the family and recommend what best serves the child, with the child’s safety taking priority.¹¹ The CFI interviews both parents, may speak with the child, and investigates any safety concerns. The written report and recommendations go to the judge, and the CFI can be called as a court-appointed expert.

Cost is the part that catches parents off guard. The presumptive maximum fee for a CFI’s investigation and report is $3,250, with an additional cap of $500 for testimony and preparation. Either cap can be exceeded only by written court order explaining the extraordinary circumstances.¹² The court decides how the fees are split.

Modifying Parenting Time Later

Minor schedule adjustments are decided under the standard best-interests test. A substantial change that would shift which parent the child lives with most of the time is much harder.¹³ For a major modification, the parent asking for the change must show changed circumstances (or facts that existed but weren’t known at the time of the original order), that the change serves the child’s best interests, and that at least one of these applies:

Both parents agree to the change.
The child has been integrated into the requesting parent’s household with the other parent’s consent.
The residential parent intends to relocate in a way that substantially changes the child’s geographic ties to the other parent.
The child’s current environment endangers their physical health or significantly impairs their emotional development, and the benefit of a change outweighs the harm of disruption.

After a major modification motion is decided, a two-year cooling-off period kicks in. No new motion for a substantial change can be filed within those two years unless the current environment endangers the child or a relocation is planned that would substantially change the child’s geographic ties to the other parent.

Courts also can’t restrict a parent’s existing parenting time unless that time would endanger the child’s physical health or significantly impair their emotional development, and the judge must state specific factual findings supporting any restriction imposed.

Moving With the Child

Relocation is one of the most heavily litigated issues in Colorado custody cases. When the parent with majority overnights plans to move to a residence that would substantially change the child’s geographic ties to the other parent, that parent must give written notice as soon as practicable — stating the intended new location, the reason for the move, and a proposed revised parenting time schedule. If the other parent objects, the court holds a hearing that receives priority on the docket.

On top of the standard best-interests factors, the judge weighs:

Why the relocating parent wants to move and why the other parent objects.
The history and quality of each parent’s relationship with the child.
Educational opportunities at both the current and proposed locations.
The presence of extended family at each location.
Any advantages of the child remaining with the primary caregiver.
The anticipated impact of the move on the child.
Whether a workable parenting time schedule can be designed if the move is allowed.

Judges don’t rubber-stamp moves, even for a good reason like a job offer or family support. If the move would make the other parent’s meaningful involvement nearly impossible, the court can deny it outright or change which parent is primary.

Enforcing the Order

A parenting time order is a court order, and ignoring it has real consequences. When one parent consistently denies or fails to exercise court-ordered parenting time, the other parent can file a verified motion alleging noncompliance. The court has 35 days from filing to determine whether substantial or continuing noncompliance occurred, and may set a hearing or send the parents to mediation.¹⁴

If the court finds a violation, available remedies include:

Makeup parenting time of the same type and duration as what was denied — weekends for weekends, holidays for holidays — scheduled at the aggrieved parent’s choosing, within six months of the violation or one year for holidays.
A civil fine of up to $100 per incident of denied parenting time.
A finding of contempt of court, which can include a jail sentence.
Court-ordered parenting education or family counseling at the violating parent’s expense.
A bond guaranteeing future compliance.
Modification of the existing order.

Fees cut both ways. If the court finds a violation, the offending parent pays the other parent’s attorney fees, court costs, and expenses for bringing the enforcement action. If the motion is denied and no violation is found, the parent who filed can be ordered to pay the other side’s costs instead. Filing an enforcement motion without solid evidence is a gamble that can backfire.
