Colorado has a few financial rules that often surprise people going through a divorce. It's an equitable distribution state — meaning courts divide marital property fairly, not automatically down the middle. Spousal support is called "maintenance," and Colorado is one of the few states with an advisory formula to help estimate it. Child support went through significant changes in 2026. And unlike many states, Colorado is strictly no-fault — meaning marital misconduct has no effect on how assets or support are divided.

Property Division: Equitable Distribution, Not Automatic 50/50
Colorado divides marital property under C.R.S. § 14-10-113. Equitable distribution means courts divide assets in a way they consider fair — not necessarily equal. Judges weigh the relevant circumstances of each case, and a 60/40 or even 70/30 outcome is possible when the facts support it.
Marital property generally includes everything acquired by either spouse during the marriage — real estate, bank accounts, investment accounts, retirement savings, vehicles, and business interests. It doesn't matter whose name is on the title; if it was acquired during the marriage with marital funds, it's typically treated as marital property. Separate property — assets one spouse owned before the marriage, inheritances, and gifts received individually — is generally excluded from division.
One important caution: if separate property becomes commingled with marital funds — for example, an inheritance deposited into a joint checking account — it may lose its separate character. Good documentation of separate assets matters.
The factors courts weigh under C.R.S. § 14-10-113 include: each spouse's contribution to acquiring marital property (including contributions as a homemaker), the value of property being set apart to each spouse, the economic circumstances of each spouse when the division becomes effective, and whether the spouse with primary custody should be awarded the family home. Courts also consider any increases or decreases in the value of separate property during the marriage, and any depletion of separate property for marital purposes.
Suppose a couple has $480,000 in total marital assets: a home with $200,000 in equity, a 401(k) with $160,000, and $120,000 in joint savings. A judge starting from a rough midpoint might consider each spouse receiving around $240,000. But if one spouse contributed significantly more to career earnings while the other sacrificed income for caregiving, or if one spouse has substantially lower future earning capacity, the court might shift the split to 55/45 or adjust the mix of assets assigned to each. Every outcome depends on how the statutory factors apply to the specific facts of the marriage.

Maintenance: Colorado's Advisory Formula for Spousal Support
Colorado uses the term "maintenance" rather than alimony — it's the same concept, just different language. The governing statute is C.R.S. § 14-10-114. What makes Colorado unusual among equitable distribution states is that it has an advisory formula for calculating the amount.
The formula works like this: take 40% of the higher earner's monthly adjusted gross income, subtract 50% of the lower earner's monthly adjusted gross income. The result may not exceed 40% of the couple's combined monthly adjusted gross income. This is a starting point, not a binding rule — courts may deviate based on the specific circumstances of the marriage.
Suppose Spouse A earns $9,000 per month and Spouse B earns $3,000 per month.
40% of Spouse A's income: $3,600. 50% of Spouse B's income: $1,500. The formula produces $3,600 − $1,500 = $2,100 per month as a starting estimate.
The cap check: 40% of combined income ($12,000) = $4,800. Since $2,100 is below the cap, the cap doesn't apply here. This is an estimate only — courts may arrive at a different figure based on each spouse's circumstances, the standard of living during the marriage, and other factors.
Before any maintenance is considered, the court first asks two threshold questions: does the spouse seeking maintenance lack sufficient property to meet their reasonable needs, and can they support themselves through employment? If the answer to both is no, maintenance may not be appropriate. If the answer is yes, the formula provides a starting range.
For duration, Colorado courts use advisory guidelines tied to the length of the marriage. Shorter marriages tend to produce shorter maintenance periods. Marriages of 20 years or more give courts broader discretion, and maintenance may be considered for an extended period. As with the amount, the duration guidelines are advisory — judges can and do deviate based on the full picture of the case.
| Marriage Length | Advisory Duration Approach |
|---|---|
| Under 3 years | Maintenance may not be awarded; courts assess whether it's appropriate at all |
| 3–10 years | Duration guidelines suggest a fraction of the marriage length as a starting point |
| 10–20 years | Longer duration considered; courts weigh earning capacity and standard of living |
| 20+ years | Courts have broad discretion; extended maintenance may be appropriate in some cases |

Child Support: Income Shares Model, Updated in 2026
Colorado calculates child support using the Income Shares Model under C.R.S. § 14-10-115. The model combines both parents' adjusted gross incomes, then looks up the basic child support obligation on a state schedule. Each parent pays their proportional share based on their percentage of the combined income.
Colorado uses adjusted gross income — which may include wages, self-employment income, investment income, rental income, and other sources. Certain deductions are allowed, such as other court-ordered support obligations. The state's Schedule of Basic Child Support Obligations then converts the combined income to a monthly obligation for the number of children involved.
Parenting time is a key variable. When parents share parenting time, each parent's support obligation is calculated separately based on the nights the child spends with them. The parent with more overnights typically receives a net payment from the other parent. The more time each parent spends with the child, the more the obligations offset each other.
Suppose Parent A earns $5,500 per month in adjusted gross income and Parent B earns $2,500 per month. Combined income is $8,000. For one child, the basic obligation from the state schedule at that income level might be approximately $1,100 per month. Parent A's share would be roughly 69% ($759/month) and Parent B's share roughly 31% ($341/month). If the child lives primarily with Parent B, Parent A may pay the difference toward Parent B. Adjustments for health insurance and childcare are added on top and split proportionally. These figures are illustrative — actual results depend on the current schedule, specific income figures, and parenting time arrangement.

Retirement Accounts: QDROs and the Coverture Fraction
Retirement accounts accumulated during the marriage are marital property in Colorado and subject to equitable distribution. The portion earned before the marriage is generally separate property. Courts use the coverture fraction — months of marriage overlapping with the retirement plan divided by total months in the plan — to identify the marital share of each account.
Dividing a 401(k), 403(b), or pension typically requires a Qualified Domestic Relations Order (QDRO) — a court order that directs the plan administrator to split the account. A properly executed QDRO allows the transfer to happen without triggering early withdrawal penalties or taxes at the time of the transfer. Without one, accessing retirement funds early could result in significant tax consequences.
Colorado Public Employees' Retirement Association (PERA) accounts — a common retirement plan for state employees, teachers, and other public workers — are not divided by QDRO. PERA has its own domestic relations order (DRO) process, and the procedures differ from private-sector retirement accounts. If a PERA account is at issue, working with an attorney familiar with PERA division is especially important.
