Colorado Divorce Laws

Overview: Divorce in Colorado

Colorado's progressive family law uses forward-thinking terminology — "parental responsibility" instead of "custody" — and adopted clear maintenance guidelines in 2014. The state's no-fault-only system focuses on equitable financial outcomes rather than blame.

Whether you are considering filing for divorce, navigating a custody dispute, or evaluating your options for spousal support, understanding Colorado's specific laws is the essential first step. This guide covers the key legal requirements and rules that apply to divorces filed in Colorado.

Residency Requirements

At least one spouse must have been a Colorado domiciliary for at least 91 days before filing.

Filing before the residency requirement is met will result in the court dismissing your petition. If you have recently moved to Colorado or are considering which state to file in, confirming residency eligibility is the critical first step. An experienced Colorado family law attorney can confirm whether you currently qualify to file.

Grounds for Divorce in Colorado

Colorado is a pure no-fault state. The only ground is "irretrievable breakdown of the marriage." Fault and marital misconduct are not considered in any financial determinations.

For most divorcing couples, no-fault divorce is the most practical choice — it avoids the time and cost of proving marital fault in court. However, in states where fault can influence financial outcomes, discussing grounds strategy with your attorney before filing is worthwhile.

Property Division in Colorado

Colorado divides marital property equitably. Courts consider each spouse's economic circumstances, contributions to the marriage (including as a homemaker), and depletion of assets.

Marital property generally includes assets and debts acquired during the marriage, while separate property (owned before marriage, or received as a gift or inheritance) is typically excluded. Complex assets like retirement accounts, business interests, and real estate often require professional valuation and careful legal handling.

Waiting Periods & Timeline

There is a 91-day waiting period from the date of service before the divorce can be finalized. This is tied to the residency requirement.

Even in states without a mandatory waiting period, the practical timeline for divorce — from filing to final decree — typically ranges from 60 days for simple uncontested cases to 12–24 months for contested divorces. Contested issues like property valuation, business interests, or custody disputes can extend timelines significantly.

Child Custody in Colorado

Colorado uses "parental responsibility" rather than "custody" — reflecting the view that both parents retain responsibilities for their children after divorce. Courts focus on what allocation of parenting time and decision-making serves the child's best interests.

Child custody decisions are not permanent — they can be modified after the initial order if there is a substantial change in circumstances. Courts in Colorado will always prioritize the best interests of the child over the preferences of either parent.

Types of Custody

• Legal custody — the right to make major decisions about the child's education, healthcare, and religious upbringing
• Physical custody — where the child primarily lives
• Joint custody — both parents share legal and/or physical custody
• Sole custody — one parent has primary legal and/or physical custody

Alimony & Spousal Support in Colorado

Colorado calls spousal support "maintenance." A 2014 reform created advisory guidelines based on the spouses' combined income and length of marriage, providing more predictable outcomes. Courts may deviate from the guidelines based on circumstances.

Alimony is not automatically awarded in Colorado and is not available in every divorce. The requesting spouse must demonstrate financial need, and the court must find that the other spouse has the ability to pay. If you believe you may be entitled to spousal support — or may be required to pay it — consulting with a Colorado family law attorney early in the process is important.

What Makes Colorado Divorce Law Distinctive

Colorado's 2014 maintenance reform introduced advisory formulas giving Colorado one of the more predictable alimony frameworks in the country, while still allowing judicial discretion.
