Colorado divorce law lets either spouse end a marriage without proving fault, but the court imposes two timing rules that cannot be waived: one spouse must have been domiciled in Colorado for at least 91 consecutive days before filing, and at least 91 more days must pass after the other spouse is served before a judge can sign the decree.1Justia Law. Colorado Code 14-10-106 – Dissolution of Marriage Everything else — property division, maintenance, parenting time, child support — gets resolved inside that window or at a later hearing if the spouses can’t agree.
Who Can File and When
Domicile means more than physical presence. The spouse filing in Colorado must intend to remain here, and voter registration, a Colorado driver’s license, and local employment all help show that intent. If only one spouse lives in Colorado, the court can still dissolve the marriage, but it may lack authority to divide property or order maintenance when the out-of-state spouse has no meaningful ties to the state.
Child custody has its own jurisdictional rule. Under the Uniform Child Custody Jurisdiction and Enforcement Act, a Colorado court can issue initial custody orders only if Colorado is the child’s “home state,” meaning the child has lived here for at least 182 consecutive days before the case was filed.2Justia Law. Colorado Code 14-13-201 – Initial Child-Custody Jurisdiction The rule stops a parent from relocating shortly before filing to pick a favorable court.
Because Colorado is a no-fault state, the petition only needs to allege that the marriage is irretrievably broken. Adultery, cruelty, and similar grounds do not need to be proved and generally do not affect property division or maintenance.
Filing the Petition and Serving the Other Spouse
A divorce starts when one spouse files a Petition for Dissolution of Marriage in the district court for the county where either spouse lives.3Justia Law. Colorado Code 14-10-107 – Commencement, Pleadings, Abolition of Existing Defenses, Automatic Temporary Injunction, Enforcement The filing fee is $260, with a Case Information Sheet attached.4Colorado Judicial Branch. List of Fees A spouse who can’t afford the fee can file a motion to waive it with supporting financial documentation.
Unless both spouses file jointly, the other spouse (the respondent) has to be formally served. Once served inside Colorado, the respondent has 21 days to file a response. If served outside the state, that deadline stretches to 35 days. Missing it can produce a default judgment.
The 91-day clock to finalize does not start at filing; it starts when the court has jurisdiction over the respondent, which usually means the date of service. During that 91 days, both spouses must exchange mandatory financial disclosures covering income, assets, debts, and expenses. If contested issues remain, the court may refer the case to mediation, though it will not order mediation when one party reports being a victim of physical or psychological abuse and is unwilling to participate.5Justia Law. Colorado Code 13-22-311 – Court Referral to Mediation
The Automatic Temporary Injunction
The moment the respondent is served, an injunction takes effect against both spouses and stays in place until the divorce is final. No judge has to sign anything; it applies by operation of law. The injunction restrains four categories of conduct:3Justia Law. Colorado Code 14-10-107 – Commencement, Pleadings, Abolition of Existing Defenses, Automatic Temporary Injunction, Enforcement
- Transferring, hiding, or encumbering marital property without the other spouse’s consent or a court order. Routine spending on necessities and ordinary business operations is allowed; unusual expenditures must be reported.
- Harassing or disturbing the peace of the other spouse.
- Removing the children from Colorado without the other parent’s consent or court approval.
- Canceling, modifying, or letting lapse any health, homeowner’s, renter’s, auto, or life insurance policy that covers either spouse or the children, without at least 14 days’ written notice and either the other party’s consent or a court order.
The insurance provision catches people off guard. A spouse who drops the other from a health plan or lets a life insurance policy lapse during the divorce has violated a court order, even if no judge ever told them not to.
How Property and Debts Get Divided
Colorado divides marital property equitably, which means fairly rather than automatically 50/50. The court weighs each spouse’s contributions to acquiring the property (including work as a homemaker), the economic circumstances of each spouse at the time of division, the value of the property each will keep, and any increase or decrease in the value of separate property during the marriage.6Justia Law. Colorado Code 14-10-113 – Disposition of Property
Only marital property is divided. Marital property generally includes real estate, bank accounts, retirement funds, vehicles, and business interests acquired during the marriage. Separate property — assets owned before the marriage or received as a gift or inheritance during it — usually stays with the original owner. There is one important exception: separate property that gets mixed with marital funds can be reclassified entirely as marital. Keeping inherited or premarital assets in a dedicated, untouched account is the only reliable way to preserve their separate character.
Debts incurred during the marriage are divided along with assets, regardless of whose name is on the account. A court can assign a debt disproportionately to the spouse who primarily benefited from the spending.
Retirement Accounts, Businesses, and Real Estate
Dividing a 401(k) or pension requires a Qualified Domestic Relations Order, or QDRO, which tells the plan administrator to transfer a portion of the account to the other spouse.7Internal Revenue Service. Retirement Topics – QDRO Qualified Domestic Relations Order A properly drafted QDRO lets the receiving spouse roll the funds into their own retirement account without income tax, and distributions made under a QDRO escape the 10% early withdrawal penalty even if the recipient is under 59½.8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions That penalty exception applies to employer-sponsored plans; IRAs follow different rules.
Businesses typically need valuation by a forensic accountant, and real estate usually needs a formal appraisal. Transferring real property between divorcing spouses may require a special warranty deed to remove a name from title.
Spousal Maintenance
Maintenance (Colorado’s word for alimony) can be ordered when one spouse needs support and the other has the ability to pay. The court looks at both spouses’ incomes and employment prospects, the length of the marriage, the marital standard of living, and each spouse’s financial resources.9Justia Law. Colorado Code 14-10-114 – Spousal Maintenance, Advisory Guidelines, Legislative Declaration, Definitions
For marriages of 3 to 20 years with combined adjusted gross income of $240,000 per year or less, an advisory formula produces a starting amount: 40% of the couple’s combined monthly adjusted gross income minus the lower earner’s monthly adjusted gross income. Because post-2018 maintenance isn’t tax-deductible to the payer, the guideline is further reduced to 80% of the base calculation when combined monthly gross income is $10,000 or less, and to 75% when combined monthly gross income is between $10,001 and $20,000.
Recommended duration scales with the length of the marriage, from 31% of the marriage’s length at three years up to 50% at twenty years. For marriages over 20 years, a court may order maintenance for a set term or indefinitely. These are advisory guidelines, not mandatory numbers, and judges can depart from them.
Tax treatment hinges on the date of the agreement. For any divorce or separation agreement finalized after December 31, 2018, maintenance is not deductible by the payer and not taxable to the recipient.10Internal Revenue Service. Topic No. 452, Alimony and Separate Maintenance Older agreements keep the prior treatment (deductible to payer, taxable to recipient) unless a later modification expressly adopts the new rule.
Parental Responsibilities and Child Support
Colorado doesn’t use “custody.” Courts allocate “parental responsibilities,” which cover both decision-making authority and parenting time. The guiding standard is the child’s best interests, with the child’s safety at the top of the list.11Justia Law. Colorado Code 14-10-124 – Best Interests of the Child The court weighs each parent’s ability to cooperate, the child’s relationships with each parent and siblings, the child’s adjustment to home and school, and any history of domestic violence or substance abuse.
Decision-making authority covers major decisions about education, healthcare, religion, and extracurricular activities. It can be joint, sole to one parent, or split by category. Parenting time is the physical schedule. Both go into a Parenting Plan, which the parents can draft together or the court will impose if they can’t agree.
Both parents remain financially responsible for the children regardless of parenting time. Colorado calculates child support with a statutory guideline that uses each parent’s adjusted gross income, the number of overnights with each parent, and additional costs like health insurance premiums and work-related childcare.12Justia Law. Colorado Code 14-10-115 – Child Support Guidelines When parenting time is roughly equal, the calculation adjusts upward by a factor of 1.5 to reflect duplicated household expenses, and the two parents’ obligations are offset.
Child support generally runs until the child turns 19. If the child hasn’t graduated from high school by 19, support can continue until graduation; it can also continue for a child with a mental or physical disability. Enforcement tools for unpaid support include wage garnishment, interception of tax refunds, driver’s license suspension, and contempt proceedings.
Benefits That Change at the Decree
Health Insurance
A spouse covered under the other spouse’s employer plan loses coverage when the divorce is final. Under COBRA, the former spouse can continue the same group coverage for up to 36 months, but at the full premium plus a 2% administrative fee, since the employer no longer subsidizes it.13Centers for Medicare and Medicaid Services. COBRA Continuation Coverage Questions and Answers The employer must be notified of the divorce within 60 days for the former spouse to be eligible.
Social Security on an Ex-Spouse’s Record
A divorced spouse can draw Social Security on the ex-spouse’s earnings record if the marriage lasted at least 10 years, the divorced spouse is at least 62, is not currently married, and would receive less on their own record than as a divorced spouse.14Social Security Administration. Code of Federal Regulations 404-0331 If the earning ex-spouse hasn’t filed yet, the divorced spouse also has to have been divorced for at least two years. Claiming on an ex’s record does not reduce what the ex or the ex’s current spouse receives.
Legal Separation as an Alternative
Colorado also offers legal separation, which resolves all the same issues — property, debts, maintenance, child support, parental responsibilities — without legally ending the marriage.15Colorado Judicial Branch. Divorce or Legal Separation The same 91-day residency rule applies. Couples choose this path for religious reasons, to preserve a spouse’s health coverage (since the marriage legally continues), or because they aren’t yet sure the marriage is over. Either spouse can later convert the separation into a divorce.
Changing or Enforcing the Orders Later
The Decree of Dissolution of Marriage finalizes the divorce. Maintenance and child support can be modified when either party shows a substantial and continuing change in circumstances, such as a job loss, a significant income shift, relocation, or a change in the child’s needs.16Justia Law. Colorado Code 14-10-122 – Modification and Termination of Provisions for Maintenance, Support, and Property Disposition There’s a practical floor on child support changes: if applying the guideline to the new numbers would change the monthly amount by less than 10%, the court won’t treat the change as substantial. Property division is generally final and reopens only in narrow situations like fraud.
When an ex-spouse ignores the decree, the other side can file a contempt motion, and willful noncompliance can bring fines or jail. Parenting time violations are handled through enforcement motions, which can produce make-up time, a modified schedule, or a referral to mediation.17Justia Law. Colorado Code 14-10-129 – Modification of Parenting Time
