Colorado Family Law Statutes: Marriage, Divorce, Custody, Adoption

Colorado family law is set out mainly in Title 14 of the Colorado Revised Statutes and covers who can marry, how a marriage ends, how property and debts are split, how parenting decisions get made, and how child support and spousal maintenance are calculated. The state is no-fault for divorce, uses equitable distribution for property, follows an income-shares model for child support, and speaks of “parental responsibilities” rather than custody. What follows walks through the rules that matter most if you are entering, leaving, or raising a family in Colorado.

Getting Married in Colorado

Both applicants have to appear in person at a county clerk and recorder’s office. Under C.R.S. 14-2-106, you need valid ID and a $30 fee.¹ There is no waiting period, so a couple can pick up the license and marry the same day.

Anyone 18 or older may marry without additional approval. A 16- or 17-year-old needs judicial approval, not just a parent’s signature: the court appoints a guardian ad litem, reviews a readiness report, and authorizes the marriage only if it serves the minor’s best interests. Pregnancy alone does not meet that standard, and no one under 16 may marry.¹ Marriages between close relatives, including siblings and half-siblings, are prohibited.²

Self-Solemnization

Colorado is one of the few states that lets a couple solemnize their own marriage. Under C.R.S. 14-2-109, a marriage may be solemnized “by the parties to the marriage” with no officiant, no witnesses, and no ceremony. One party fills out the certificate and returns it to the county clerk within 63 days.³ Judges, magistrates, retired judges, clergy, and public officials may also officiate.

Filing for Divorce

Colorado is a no-fault state. The only ground for dissolving a marriage is that it is “irretrievably broken.” You do not have to prove infidelity, cruelty, or any other wrongdoing.⁴ Either spouse can file a Petition for Dissolution of Marriage in the district court of any county where either party lives. The filing fee is $260.⁵

Once the petition is filed and served, a mandatory 91-day waiting period runs before the court can finalize the divorce. If both spouses agree on everything, they can submit a separation agreement covering asset division and financial responsibilities. When disputes arise, courts may order mediation before scheduling a trial.⁶ If mediation fails, a judge decides the contested issues.

Full financial disclosure is required. Under C.R.S. 14-10-113, depleting marital assets or transferring property to hide it from a spouse are factors the court weighs when dividing property.⁷ Judges may also award attorney fees to one party when the other engages in bad-faith tactics that stretch out the litigation.

Dividing Property and Debts

Colorado follows equitable distribution, so a judge divides marital assets fairly rather than automatically 50/50. Marital property covers assets acquired during the marriage, including real estate, retirement accounts, and business interests. Separate property (inheritances, gifts, and assets owned before the marriage) generally stays with the original owner.⁷

Complex assets often need forensic valuation, especially closely held businesses and investment portfolios. Courts also consider whether one spouse gave up career opportunities to support the other’s professional advancement. Debts run down the same equitable path, with the judge asking whether a given liability benefited the marriage or came from one party’s irresponsible spending.

Prenuptial and Postnuptial Agreements

A prenup or postnup can change how property is divided, but it has to hold up under C.R.S. 14-2-309. An agreement is unenforceable if the challenging party shows that consent was involuntary or the result of duress, they lacked access to independent legal representation, or they did not receive adequate financial disclosure before signing. Even an otherwise valid agreement can be struck down to the extent its spousal maintenance provisions are unconscionable at the time of enforcement.⁸

Splitting Retirement Accounts

Retirement accounts governed by federal law, including 401(k)s and pensions, cannot be split by a state divorce decree alone. A Qualified Domestic Relations Order tells the plan administrator to pay part of the participant’s benefits to an “alternate payee,” which in a divorce is the other spouse.⁹

The reason the QDRO matters is tax treatment. A spouse who receives retirement funds through a properly drafted QDRO can roll them into their own IRA without triggering early withdrawal penalties or immediate income tax. Without the QDRO, a direct distribution would be taxable and potentially hit with a 10% early withdrawal penalty.⁹

Spousal Maintenance

Spousal maintenance is Colorado’s term for alimony, and it lives in C.R.S. 14-10-114. Courts consider the length of the marriage, each spouse’s financial resources, the marital standard of living, and the recipient’s ability to become self-supporting.

For marriages that lasted between 3 and 20 years, where the couple’s combined monthly adjusted gross income is $20,000 or less, Colorado gives an advisory formula. The base calculation is 40% of the couple’s combined monthly adjusted gross income, minus the lower-earning spouse’s monthly income. Because maintenance from agreements finalized after 2018 is no longer tax-deductible for the payer or taxable to the recipient, the statute adjusts that base downward: couples with combined monthly income of $10,000 or less use 80% of the base figure, and those earning between $10,001 and $20,000 combined use 75%.¹⁰

These are advisory, not mandatory. Courts can deviate based on marital debt, employability, and other circumstances. For marriages longer than 20 years, judges have discretion to award maintenance indefinitely. A maintenance award can be modified or terminated if the receiving spouse remarries or either party has a substantial change in financial circumstances.

One tax detail is worth knowing. The 2017 Tax Cuts and Jobs Act flipped the treatment of maintenance for any divorce finalized after December 31, 2018. The paying spouse cannot deduct payments, and the receiving spouse does not report them as income.¹¹ Agreements finalized before 2019 still follow the old rules unless both parties formally adopt the new treatment.

Parental Responsibilities and Parenting Time

Colorado uses “parental responsibilities” instead of “custody.” Under C.R.S. 14-10-124, courts decide based on the best interests of the child, weighing each parent’s relationship with the child, the child’s adjustment to home and community, each parent’s ability to encourage a relationship with the other parent, and the child’s own wishes if the child is mature enough to express a meaningful preference.

Parental responsibilities have two moving parts. Decision-making covers major life choices about education, health care, and religious upbringing, and can be joint or sole. Parenting time is the actual schedule. A history of domestic violence, coercive control, or substance abuse can lead the court to restrict a parent’s decision-making role or limit parenting time.

Parents can propose their own parenting plan, and courts prefer agreements the parties work out themselves. When parents cannot agree, the court may appoint a professional evaluator. A Child and Family Investigator conducts a focused evaluation and issues a shorter report; fees are capped at $3,309, with additional charges possible for testimony or discovery, and CFIs do not perform psychological testing. A Parental Responsibilities Evaluator conducts a more extensive evaluation that may include psychological testing, has no statutory fee cap, and often runs above $5,000, typically appointed in high-conflict cases involving mental health concerns or abuse allegations.¹²

Child Support

Colorado uses an income-shares model under C.R.S. 14-10-115. Start by figuring what both parents would have spent on the child together, then split that amount between them in proportion to their incomes. Gross income is defined broadly and includes wages, salaries, bonuses, commissions, severance, rental income, trust income, capital gains, Social Security benefits, and more.¹³

The number of overnights each parent has affects the calculation directly. Medical expenses, childcare costs, and health insurance premiums for the child are folded in. Uninsured medical expenses and work-related childcare are shared proportionally by income, and health insurance premiums a parent pays for the child are credited against that parent’s obligation.

When Support Ends

Child support automatically ends when the child turns 19, unless the child is still in high school. In that case, support continues until the end of the month following graduation, but not beyond age 21. For a child with a physical or mental disability, the court may order support to continue past 19.¹³

Child support payments are not tax-deductible for the paying parent and are not taxable income for the receiving parent.¹⁴ What can be negotiated is which parent claims the child as a dependent: the custodial parent typically gets the exemption, but parents can agree on IRS Form 8332 to let the noncustodial parent claim the child instead, which affects eligibility for the child tax credit.

Enforcement

Colorado can garnish wages, intercept tax refunds, suspend driver’s licenses, and hold a delinquent parent in contempt of court. At the federal level, the Treasury Offset Program matches delinquent child support debts against federal payments like tax refunds and withholds the money to cover the arrears.¹⁵

Protection Orders

Colorado grants civil protection orders in cases of domestic abuse, stalking, sexual violence, threatened bodily harm, and emotional abuse of an elderly or at-risk adult. Under C.R.S. 13-14-104.5, any county, district, probate, or juvenile court can issue a temporary or permanent protection order.¹⁶ You do not need a police report or a pending criminal case to petition for one.

A temporary order can be granted on an emergency basis without the other party being present if the petitioner shows immediate danger. A hearing on whether to make the order permanent must be set within 14 days. Once made permanent, the order stays in effect indefinitely unless a court later modifies or dismisses it.¹⁶

Violating a protection order is a class 2 misdemeanor under C.R.S. 18-6-803.5, carrying potential jail time and fines. The charge rises to a class 1 misdemeanor if the restrained person has a prior conviction for the same offense, if the underlying order involved stalking or an intimate relationship, or if it is a mandatory protection order issued in a criminal case.¹⁷

Adoption

Colorado’s adoption laws sit in Title 19, Article 5 of the Colorado Revised Statutes, starting at C.R.S. 19-5-100.2. The path depends on the type of adoption.

Agency and Private Adoptions

Agency adoptions require background checks, a home study, and pre-adoption training. The home study looks at financial stability, living conditions, and emotional readiness. Home studies done by private agencies typically run from several hundred to several thousand dollars. Private adoptions, where birth parents place a child directly with adoptive parents, also require court approval and a home study. Either way, biological parents must voluntarily relinquish their parental rights, or a court must terminate them for neglect, abandonment, or abuse.

Stepparent and Kinship Adoptions

Stepparent adoptions move faster when the other biological parent consents. Without consent, the stepparent typically has to show abandonment for at least one year or failure to provide financial support. Kinship adoptions, where a grandparent, aunt, uncle, or other relative takes on legal parental rights, follow similar procedures but often get expedited consideration because of the existing relationship. Once finalized, an adoption is permanent and gives the adoptive parents full legal rights and responsibilities.

When Another State Is Involved

Colorado family law does not automatically apply just because you or your ex now live here. Two uniform laws control what a Colorado court can do when parents are in different states.

For custody, Colorado follows the Uniform Child-Custody Jurisdiction and Enforcement Act. Under C.R.S. 14-13-201, a Colorado court has jurisdiction to make an initial custody determination only if Colorado is the child’s “home state,” meaning the child has lived here for at least six consecutive months (or 182 days) before the case is filed. Temporary absences still count toward the six months.¹⁸ Filing in the wrong state can waste months and thousands of dollars.

For child support across state lines, the Uniform Interstate Family Support Act (adopted in Colorado under Title 14, Article 5) governs registration and enforcement of support orders. A parent who moves to another state cannot ignore a Colorado support order. The order remains enforceable, and the receiving parent can register it in the new state without relitigating the underlying amount.

Military divorces bring in a third layer of federal law. The Uniformed Services Former Spouses’ Protection Act lets state courts treat military retired pay as divisible property. For the Defense Finance and Accounting Service to make direct payments to the former spouse, the couple must have been married at least 10 years during which the service member completed at least 10 years of creditable military service. This is the “10/10 rule.” Child support and alimony orders can be enforced regardless of the 10/10 threshold.¹⁹
