Colorado courts determine child custody, legally called "allocation of parental responsibilities," based on 11 statutory factors under C.R.S. § 14-10-124. The filing fee is $230 as of January 2026, children must reside in Colorado for 182 days before filing, and the court strongly favors joint decision-making in over 90% of cases absent domestic violence, substance abuse, or mental health concerns.

What Is "Allocation of Parental Responsibilities" in Colorado?
Colorado eliminated the terms "custody" and "visitation" in 1998, replacing them with "allocation of parental responsibilities" under C.R.S. § 14-10-124. This terminology reflects the state's philosophy that both parents should share in raising their children after separation. The allocation includes two distinct components: parenting time (when the child is physically with each parent) and decision-making responsibility (who makes major life decisions for the child). Colorado courts recognize that parenting time and decision-making are separate issues, meaning a parent can have equal parenting time but sole decision-making, or vice versa.
The Colorado General Assembly declared in C.R.S. § 14-10-124 that "it is in the best interest of all parties to encourage frequent and continuing contact between each parent and the minor children." This legislative intent guides judges toward arrangements that maximize both parents' involvement unless safety concerns exist. The statute urges parents to "share the rights and responsibilities of child-rearing" and maintain love, affection, and contact between children and both parents.
The Best Interests of the Child Standard
Colorado courts must determine parental responsibilities "in accordance with the best interests of the child, giving paramount consideration to the child's safety and the physical, mental, and emotional conditions and needs of the child" under C.R.S. § 14-10-124(1.5). This standard places the child's welfare above either parent's preferences or desires. The statute explicitly prohibits courts from presuming either parent is better suited based on sex, ensuring gender-neutral custody determinations.
Statutory Factors for Parenting Time
Under C.R.S. § 14-10-124(1.5)(a), Colorado courts must consider all relevant factors including:
- The wishes of both parents regarding parenting time arrangements
- The child's wishes if sufficiently mature to express reasoned, independent preferences
- The interaction and relationships between the child and parents, siblings, and other significant persons
- The child's adjustment to home, school, and community
- The mental and physical health of all individuals involved (disability alone cannot restrict parenting time)
- Each parent's ability to encourage love, affection, and contact with the other parent
- The past pattern of parental involvement reflecting values, time commitment, and mutual support
- The physical proximity of the parents to each other for practical parenting considerations
- Any credible evidence of domestic violence, child abuse, or coercive control
- Reports from child and family investigators or parental responsibility evaluators
- Whether a parent has been convicted of certain crimes including child abuse or domestic violence
Decision-Making Responsibility Factors
For allocating decision-making responsibility, courts consider additional factors under C.R.S. § 14-10-124(1.5)(b):
- Credible evidence of the parties' ability to cooperate and make joint decisions
- Whether past parental involvement demonstrates values and mutual support indicating ability as mutual decision-makers
- Whether joint decision-making on specific issues will promote more frequent contact between the child and each parent
Types of Decision-Making Responsibility in Colorado
Colorado courts award decision-making responsibility in three configurations: joint (mutual), sole, or split. Joint decision-making means both parents must agree on major decisions regarding the child's education, healthcare, religious training, and extracurricular activities. Sole decision-making grants one parent exclusive authority over these major decisions. Split decision-making divides authority by category, such as one parent deciding educational matters while the other decides medical issues.
Joint Decision-Making (Most Common)
Joint decision-making is awarded in over 90% of Colorado custody cases absent domestic violence, mental illness, substance abuse, or geographic distance that makes cooperation impractical. Under C.R.S. § 14-10-124, the statute favors joint awards when parents demonstrate the ability to cooperate. Even parents who disagree on some issues often receive joint decision-making with provisions for resolving disputes through mediation or parenting coordinators.
Sole Decision-Making
Courts award sole decision-making when credible evidence shows parents cannot make joint decisions together. If one parent has committed domestic violence, the court "shall not order joint parental responsibilities and decision-making over the objection of the other party" unless the court specifically finds the parents can still make joint decisions. Sole decision-making does not affect parenting time, meaning the non-decision-making parent retains their scheduled time with the child.
Common Parenting Time Schedules in Colorado
Colorado courts commonly start from a presumption of equal parenting time (50/50) when practical for the child's schedule and the parents' proximity, though no statutory presumption exists. The most frequently ordered schedules include the 2-2-5-5 rotation, week-on/week-off exchanges, and 70/30 arrangements for parents with greater distance between homes.
50/50 Parenting Time Schedules
| Schedule Type | Description | Best For |
|---|---|---|
| 2-2-5-5 (2-2-3) | Two days with Parent A, two with Parent B, then five with each alternating | Children who adapt well to frequent transitions |
| Week-on/Week-off | Seven consecutive days with each parent | Older children; parents living farther apart |
| 5-2-2-5 | Five days with one parent, two with the other, then reverse | Parents wanting mid-week contact |
70/30 and 80/20 Schedules
For families where equal time is impractical, courts may order a 70/30 schedule (every other weekend plus one midweek overnight) or an 80/20 schedule (every other weekend without midweek time). These arrangements are common when parents live more than 30-45 minutes apart, when work schedules conflict with school nights, or when children struggle with frequent transitions.
2026 Child Support Changes Affecting Parenting Time
Starting March 1, 2026, Colorado's child support guidelines underwent major changes under updated C.R.S. § 14-10-115. The previous 92-overnight threshold for "shared custody" credit has been eliminated. Under the new law, every overnight counts from the first one, creating a smooth curve that reduces support obligations proportionally rather than a dramatic cliff at 93 overnights.
The 2026 changes define "Shared Physical Care" as each parent having the children for at least one overnight per year. This eliminates strategic scheduling to reach the old 93-overnight threshold and focuses parenting time decisions purely on the child's best interests rather than financial implications. The income cap for guideline calculations has also increased, affecting high-income families.
Residency Requirements for Colorado Custody Cases
Colorado imposes different residency requirements for divorcing parents and for children in custody proceedings. Understanding these requirements prevents jurisdictional problems that could delay your case or result in dismissal.
Parent Residency (91 Days)
At least one spouse must have resided in Colorado for at least 91 days immediately before filing for divorce under C.R.S. § 14-10-106(1)(a)(I). This requirement applies regardless of where the marriage occurred. Both spouses do not need to be Colorado residents; one qualifying spouse is sufficient.
Child Residency (182 Days)
Under the Uniform Child Custody Jurisdiction and Enforcement Act (UCCJEA), codified at C.R.S. § 14-13-201, Colorado courts have jurisdiction over custody matters only if the child has lived in Colorado for at least 182 consecutive days (approximately six months) before filing. For infants under six months old, the child must have lived in Colorado since birth. If your child has not met this requirement, you may need to file for custody in the state where the child most recently resided for 182 days.
Modifying Parenting Time and Decision-Making
Colorado law imposes strict standards for modifying custody orders to provide stability for children. Under C.R.S. § 14-10-129, courts may modify parenting time "whenever such modification would serve the best interests of the child." However, modifying decision-making responsibility requires meeting a higher "endangerment" standard.
Two-Year Waiting Period
Under C.R.S. § 14-10-131, if a motion to modify custody or decision-making has been filed (whether granted or denied), no subsequent motion may be filed within two years unless the court finds reason to believe that continuing the current arrangement "may endanger the child's physical health or significantly impair the child's emotional development." This waiting period prevents parents from repeatedly litigating custody.
Substantial Change in Circumstances
To modify any custody order, the moving party must prove facts arising after the original decree (or unknown at the time) showing a change in circumstances of the child or parent, and that modification serves the child's best interests. Courts will not modify orders simply because one parent believes a different arrangement would be slightly better.
Changing the Majority Parent (Higher Standard)
Seeking to change which parent has majority parenting time requires meeting the "endangerment" standard under C.R.S. § 14-10-129(2): the current arrangement must endanger the child's physical health or significantly impair emotional development, and the harm from changing environments must be outweighed by the benefits of the change.
Relocation with Children in Colorado
Colorado law requires careful consideration before a parent can relocate with a child. Under C.R.S. § 14-10-129(2)(c), any move that "substantially changes the geographical ties between the child and the other party" requires either the other parent's consent or court permission. Even moves within Colorado can trigger relocation requirements if they significantly impact the other parent's ability to exercise parenting time.
Notice Requirements
The relocating parent must provide written notice to the other parent "as soon as practicable" including:
- The intended new location
- The reason for relocation
- A proposed revised parenting time plan
Relocation Factors
Courts consider multiple factors under C.R.S. § 14-10-129(2)(c) including:
- The reasons for and against the relocation
- The history and quality of each parent's relationship with the child
- Educational opportunities at both locations
- Extended family presence at each location
- Advantages of the child remaining with the primary caregiver
- The impact on the child's well-being
- Whether a reasonable parenting schedule can be crafted if relocation is allowed
Consequences of Unauthorized Relocation
Moving without proper notice or court approval can result in emergency motions alleging "abduction," potential jail time, fines, payment of the other parent's attorney fees, and court orders requiring return of the child to Colorado. Courts view unauthorized relocations very seriously and may modify custody in favor of the non-relocating parent.
Resolving Custody Disputes: Mediation and Parenting Coordinators
Colorado offers multiple dispute resolution options to help parents avoid costly litigation. The Colorado Office of Dispute Resolution (ODR) provides mediators in every judicial district at rates starting at $75 per hour per party with a court order, compared to $225+ per hour for private mediation.
Parenting Coordinators
Under C.R.S. § 14-10-128.5, a parenting coordinator is a neutral third party who assists parents in resolving disputes about implementing parenting plans. Unlike mediators, parenting coordinators can sometimes make binding decisions on day-to-day disputes when parents cannot agree. Courts may appoint parenting coordinators when ongoing conflict is expected or when parents request this service.
Decision-Makers
When parenting coordinators cannot resolve disputes, a decision-maker can issue binding rulings on specific issues without full court involvement. This process is faster and less expensive than returning to court for every disagreement about the parenting plan.
Child and Family Investigators (CFI) and Parental Responsibility Evaluators (PRE)
In contested custody cases, Colorado courts may appoint professionals to investigate and make recommendations. Child and Family Investigators (CFIs) conduct investigations including interviews with parents, children, and collateral contacts, home visits, and review of relevant records. They provide recommendations to the court but do not conduct psychological testing.
Parental Responsibility Evaluators (PREs) perform more comprehensive evaluations including mental health and substance abuse assessments, psychological testing, and in-depth analysis. PRE evaluations are typically ordered in complex cases involving allegations of abuse, mental illness, or substance abuse. Both CFI and PRE reports carry significant weight with judges, though neither is binding.
How Children's Preferences Affect Custody Decisions
Colorado courts consider a child's wishes "if he or she is sufficiently mature to express reasoned and independent preferences" under C.R.S. § 14-10-124(1.5)(a)(II). No specific age automatically grants children input, but courts generally apply the following guidelines:
| Age Range | Weight Given to Child's Preference |
|---|---|
| Under 7 | Little to no weight; considered too young |
| 8-14 | Some weight; must show reasoning behind preference |
| 15-17 | Significant weight; preference often followed if reasonable |
Courts distinguish between a child's "reasoned and independent" preference versus a preference coached or influenced by a parent. Judges and evaluators are trained to identify alienation tactics and give less weight to preferences that appear manipulated.
Domestic Violence and Custody in Colorado
Colorado law provides specific protections when domestic violence is present. Under C.R.S. § 14-10-124(4), if a parent has committed domestic violence, the court "shall not order joint parental responsibilities and decision-making over the objection of the other party" unless specifically finding the parents can still cooperate. "Coercive control," defined as a pattern of threatening, humiliating, or intimidating actions to harm, punish, or frighten an individual, is now explicitly considered.
Emergency Motions to Restrict Parenting Time
A parent may file an emergency motion under C.R.S. § 14-10-129 to restrict the other parent's parenting time for 14 days. The moving parent must demonstrate "imminent physical or emotional danger to the children." Courts take these motions seriously but require specific factual support, not general allegations.
Supervised Parenting Time
When unsupervised contact poses risks, courts may order supervised parenting time conducted at a professional supervision center, by a mutually approved third party, or with specific restrictions on activities or locations. Supervision requirements can be modified as the supervised parent demonstrates changed behavior.

Frequently Asked Questions About Colorado Child Custody
How long does a custody case take in Colorado?
Colorado requires a mandatory 91-day waiting period from service or joint filing before any divorce can be finalized, including custody orders. Contested custody cases typically take 6-12 months or longer if evaluations are needed. Uncontested cases with agreed parenting plans can conclude shortly after the 91-day minimum expires.
Can I get sole custody in Colorado?
Colorado courts award sole decision-making in cases involving domestic violence, substance abuse, mental illness, or demonstrated inability to cooperate on decisions. Sole decision-making is granted in fewer than 10% of cases. Even with sole decision-making, the other parent typically retains parenting time unless safety concerns warrant restrictions.
At what age can a child choose which parent to live with in Colorado?
Colorado has no statutory age at which a child can choose their custodial parent. Courts consider a child's reasoned preference as one factor among many. Children ages 15-17 generally receive significant weight for their preferences if they demonstrate mature reasoning. Younger children's preferences receive less weight, and children under 7 are typically considered too young for meaningful input.
What is the standard parenting time schedule in Colorado?
No statutory standard schedule exists in Colorado; courts craft schedules based on each family's circumstances. However, 50/50 parenting time has become increasingly common as a starting point in 2026. Common schedules include 2-2-5-5 rotations, week-on/week-off, and 70/30 arrangements for parents living farther apart.
Can a parent move out of state with a child in Colorado?
Relocation requires the other parent's consent or court approval under C.R.S. § 14-10-129(2)(c). You must provide written notice of your intent to relocate, proposed new location, reason for moving, and a proposed revised parenting plan. Moving without permission can result in emergency custody modifications, contempt charges, and being ordered to return the child.
How is parenting time different from decision-making in Colorado?
Parenting time refers to the physical schedule of when children are with each parent. Decision-making responsibility determines who makes major decisions about education, healthcare, religious training, and extracurricular activities. A parent can have equal parenting time but no decision-making authority, or vice versa. The two are determined separately based on different factors.
Can grandparents get custody or visitation in Colorado?
Grandparents may seek visitation under C.R.S. § 19-1-117 if the child's parent has died, the grandparent-grandchild relationship began with parental approval, and visitation is in the child's best interest. Grandparent custody is rare and typically requires showing both parents are unfit or have abandoned the child.
How do I modify an existing custody order in Colorado?
File a motion to modify in the court that issued the original order. You must show a substantial change in circumstances affecting the child or parent, and that modification serves the child's best interests. A two-year waiting period applies after any prior modification motion unless you can show endangerment. Parenting time modifications use a "best interests" standard; decision-making modifications require showing endangerment.
What happens if my co-parent violates the custody order?
File a verified motion alleging noncompliance under C.R.S. § 14-10-129.5. Courts must rule within 35 days on whether substantial noncompliance has occurred or is likely to continue. Remedies include make-up parenting time, modification of the schedule, attorney fee awards, and in severe cases, contempt of court with potential jail time.
Do I need a lawyer for a custody case in Colorado?
You have the right to represent yourself (pro se), and Colorado courts provide self-help resources through the Colorado Judicial Branch Self-Help Center. However, custody cases involve complex legal standards and long-term consequences for your children. An attorney can help ensure your parenting plan protects your rights and your children's best interests, particularly in contested cases or those involving domestic violence, substance abuse, or relocation.
