Colorado spousal maintenance (alimony) lasts between 11 months and 10 years under the advisory guidelines in C.R.S. § 14-10-114. A 3-year marriage yields approximately 11 months of maintenance, while a 20-year marriage yields up to 120 months (10 years). Marriages exceeding 20 years may qualify for indefinite maintenance at the court's discretion. The duration is calculated as a percentage of the marriage length, starting at 31% for a 36-month marriage and capping at 50% for marriages of 150 months (12.5 years) or longer.

How Long Does Alimony Last in Colorado Based on Marriage Length?
Colorado alimony duration follows a statutory advisory guideline table under C.R.S. § 14-10-114(3)(b)(II)(B). The guideline duration starts at 31% of the marriage length for a 3-year marriage (yielding 11 months of maintenance) and increases incrementally. The percentage caps at 50% for marriages lasting 12.5 years or longer. For a 10-year marriage, the advisory guideline recommends 54 months (4.5 years) of spousal maintenance. For a 20-year marriage, the guideline recommends 120 months (10 years).
Colorado courts are not bound by these advisory guidelines. Judges may deviate from the recommended duration based on the specific facts of each case, but the guidelines serve as the starting point in virtually every maintenance determination. The following table shows the complete statutory duration schedule that Colorado courts use when deciding how long alimony lasts.
| Marriage Length | Percentage of Marriage | Guideline Maintenance Duration |
|---|---|---|
| 36 months (3 years) | 31% | 11 months |
| 48 months (4 years) | 33% | 16 months |
| 60 months (5 years) | 35% | 21 months |
| 72 months (6 years) | 37% | 27 months |
| 84 months (7 years) | 39% | 33 months |
| 96 months (8 years) | 41% | 39 months |
| 108 months (9 years) | 43% | 46 months |
| 120 months (10 years) | 45% | 54 months |
| 132 months (11 years) | 47% | 62 months |
| 144 months (12 years) | 49% | 71 months |
| 150 months (12.5 years) | 50% | 75 months |
| 168 months (14 years) | 50% | 84 months |
| 180 months (15 years) | 50% | 90 months |
| 204 months (17 years) | 50% | 102 months |
| 240 months (20 years) | 50% | 120 months (10 years) |
For marriages shorter than 36 months, Colorado courts have no advisory guideline and may award maintenance only in limited circumstances. For marriages exceeding 240 months (20 years), Colorado courts may award maintenance for a specified term of at least 120 months or for an indefinite duration under C.R.S. § 14-10-114(3)(b)(II)(C).
How Is the Colorado Alimony Amount Calculated?
Colorado calculates advisory spousal maintenance using a statutory formula under C.R.S. § 14-10-114(3)(b)(II)(A). The formula applies when the marriage lasted at least 3 years and the parties' combined adjusted gross income does not exceed $240,000 per year ($20,000 per month). The base calculation is 40% of the higher earner's monthly adjusted gross income minus 50% of the lower earner's monthly adjusted gross income, with a tax adjustment multiplier applied to the result.
The tax adjustment multiplier exists because Colorado maintenance has been non-taxable to the recipient and non-deductible for the payor since January 1, 2019, following federal tax changes enacted through HB18-1385. Colorado applies an 80% multiplier when combined monthly income is $10,000 or less, and a 75% multiplier when combined monthly income falls between $10,001 and $20,000.
Consider this example: Spouse A earns $7,000 per month and Spouse B earns $3,000 per month, for a combined income of $10,000. The base calculation is ($7,000 x 40%) minus ($3,000 x 50%), which equals $2,800 minus $1,500, or $1,300. Applying the 80% tax multiplier yields an advisory maintenance amount of $1,040 per month. When combined annual income exceeds $240,000, Colorado courts have full discretion to set maintenance amounts without any formula guidance.
What Factors Do Colorado Courts Consider for Alimony Duration?
Colorado courts evaluate 12 statutory factors under C.R.S. § 14-10-114(3)(a) when determining whether to award maintenance, how much to award, and how long alimony lasts in Colorado. Before reaching these factors, the court must first find that the requesting spouse lacks sufficient property to meet reasonable needs and is unable to support themselves through appropriate employment.
The 12 factors Colorado courts weigh include:
- Financial resources of the requesting spouse, including income from marital and separate property
- Financial resources and ability of the paying spouse to meet their own needs while paying maintenance
- Lifestyle established during the marriage
- Distribution of marital property, including whether capital or income-producing assets were allocated to reduce maintenance need
- Income, employment, and employability of both parties, including whether additional training is necessary
- Duration of the marriage
- Amount of temporary maintenance already paid
- Age and health of both parties, including significant healthcare needs
- Economic and noneconomic contributions to the marriage, including education support and homemaking
- Whether either spouse facilitated the other's career advancement or earning capacity
- Tax consequences of maintenance payments
- Any other factor the court deems relevant to a fair outcome
Colorado courts do not consider marital fault when determining alimony duration or amount. Colorado is a pure no-fault state under C.R.S. § 14-10-106, and adultery, cruelty, or other misconduct cannot increase or decrease a maintenance award.
When Does Alimony End in Colorado?
Colorado spousal maintenance terminates automatically upon the death of either party, the remarriage of the recipient spouse, or the establishment of a civil union by the recipient, under C.R.S. § 14-10-122. Maintenance also terminates when the court-ordered term expires, unless a motion to modify was filed before the expiration date. These termination events are absolute and cannot be overridden by agreement between the parties.
Colorado does not automatically terminate or reduce alimony when the recipient begins cohabitating with a new partner. Unlike states such as Florida or New Jersey, Colorado treats cohabitation differently from remarriage. However, if living with a new partner substantially reduces the recipient's financial needs, the paying spouse may file a motion to modify maintenance by demonstrating changed circumstances under C.R.S. § 14-10-122.
Retirement does not automatically end Colorado alimony obligations. Colorado law creates a rebuttable presumption of good-faith retirement when the paying spouse reaches full Social Security eligibility age, currently between 66 and 67 depending on birth year. The retiring spouse must file a motion to modify, and Colorado courts will evaluate Social Security benefits, retirement income, and both parties' financial circumstances before reducing or terminating maintenance.
Can Colorado Alimony Be Modified?
Colorado alimony can be modified if the maintenance order was not designated as non-modifiable in the parties' separation agreement, under C.R.S. § 14-10-122. The party seeking modification must demonstrate changed circumstances so substantial and continuing as to make the existing terms unfair. Common qualifying changes include job loss, significant income reduction, disability, or a substantial increase in the recipient's income.
Modifications to Colorado maintenance are effective only from the date the motion is filed with the court, not retroactively. Colorado courts cannot reduce or eliminate past-due maintenance payments that accrued before the modification motion was filed. Filing promptly after a change in circumstances is therefore critical for the paying spouse.
When parties agree that maintenance should be non-modifiable, Colorado courts will enforce that agreement. A non-modifiable maintenance order cannot be changed regardless of how dramatically either party's circumstances shift. Colorado family law attorneys frequently advise clients to consider carefully before agreeing to non-modifiable terms, particularly in long-duration marriages where financial circumstances are likely to change over 5 to 10 years of payments.
What Is the Difference Between Temporary and Permanent Alimony in Colorado?
Colorado recognizes three types of spousal maintenance: temporary maintenance awarded during the divorce proceedings, rehabilitative maintenance for a fixed term after the divorce, and indefinite maintenance with no set end date. Temporary maintenance under C.R.S. § 14-10-114(2) uses the same advisory formula as permanent maintenance and lasts only until the divorce decree is entered, typically 91 days to 18 months depending on case complexity.
| Maintenance Type | Duration | Purpose | Modifiable |
|---|---|---|---|
| Temporary | During proceedings (91 days to 18 months typical) | Support during divorce process | Yes, by court order |
| Rehabilitative (term) | Fixed period per guidelines (11 to 120 months) | Self-sufficiency transition | Yes, unless agreement says otherwise |
| Indefinite | No end date (marriages 20+ years) | Long-term support when self-sufficiency unlikely | Yes, unless agreement says otherwise |
| Nominal | Minimal amount ($1/year typical) | Preserves future modification rights | Yes |
Rehabilititative or term-based maintenance is the most common form in Colorado. Courts follow the advisory duration guidelines under C.R.S. § 14-10-114(3)(b)(II)(B) for marriages between 3 and 20 years. Indefinite maintenance is reserved primarily for marriages exceeding 20 years, where the recipient spouse's age, health, or employment history makes economic self-sufficiency unlikely. Nominal maintenance of $1 per year preserves the court's jurisdiction to increase maintenance in the future if circumstances change.
How Does Colorado Compare to Other States on Alimony Duration?
Colorado provides more structured alimony duration guidance than most states through its statutory advisory guidelines under C.R.S. § 14-10-114. Many states leave duration entirely to judicial discretion, while Colorado gives judges a specific percentage-based formula tied to marriage length. Colorado's approach falls between states with rigid formulas (like Massachusetts, which mandates specific durational limits) and states with pure judicial discretion (like Florida prior to its 2023 alimony reform).
| Factor | Colorado | Texas | California | Massachusetts |
|---|---|---|---|---|
| Maximum term (10-year marriage) | 54 months guideline | 5-7 years maximum | Half the marriage length (guideline) | 60% of marriage length (mandatory) |
| Indefinite maintenance | 20+ year marriages | Rarely awarded | 10+ year marriages | None since 2012 reform |
| Income cap for formula | $240,000 combined | $10,780/month max | No statutory cap | No statutory cap |
| Cohabitation termination | No automatic termination | No automatic termination | Court discretion | Triggers modification |
| Fault consideration | No (pure no-fault) | Yes (adultery, cruelty) | No | No |
Colorado's $240,000 combined income cap means that high-earning couples receive no formula guidance, leaving duration and amount entirely to judicial discretion. Texas caps the maintenance amount at $5,000 per month regardless of income. California and Massachusetts apply their guidelines across all income levels. Colorado's 91-day waiting period is shorter than California's 6-month waiting period but longer than Texas, which has no mandatory waiting period.
What Are the Residency Requirements for Filing for Divorce in Colorado?
Colorado requires at least one spouse to be domiciled in the state for a minimum of 91 days before filing a petition for dissolution of marriage under C.R.S. § 14-10-106. Domicile means physical presence in Colorado with the intent to make it a permanent home. Military service members stationed in Colorado satisfy this residency requirement even if their legal domicile is another state.
The 91-day residency requirement is among the shortest in the United States. By comparison, Florida requires 6 months (180 days), New York requires 1 year for certain grounds, and California requires 6 months of state residency plus 3 months of county residency. Colorado's shorter residency period means spouses can file for divorce relatively quickly after relocating to the state.
For child custody jurisdiction, Colorado applies different timing rules. Children over 6 months old must have resided in Colorado for at least 182 days before the court can exercise custody jurisdiction. Children under 6 months old must have lived in Colorado since birth. These child custody residency rules operate independently from the 91-day divorce filing requirement.
How Much Does It Cost to File for Divorce in Colorado?
The filing fee for a divorce petition in Colorado is $260 as of January 1, 2025, under C.R.S. § 13-32-101. The responding spouse pays $146 to file an answer. A joint co-petition costs $260 total with no separate response fee. Post-decree motions to modify maintenance cost $105 to file. Fee waivers are available for individuals who demonstrate financial hardship. As of March 2026. Verify with your local clerk.
Total divorce costs in Colorado vary significantly based on case complexity. An uncontested divorce with no disputes over maintenance or property may cost $500 to $3,000 in total legal fees. A contested divorce involving spousal maintenance disputes, property division disagreements, and custody battles typically costs $15,000 to $50,000 or more in combined attorney fees, expert witnesses, and court costs. Mediation, which Colorado courts frequently recommend, costs $3,000 to $7,000 on average and can substantially reduce overall divorce expenses.
Frequently Asked Questions: Colorado Alimony Duration
How long does alimony last in Colorado for a 10-year marriage?
Colorado's advisory guideline recommends 54 months (4.5 years) of spousal maintenance for a 10-year marriage under C.R.S. § 14-10-114. The guideline calculates duration as 45% of the marriage length. Courts may deviate from this recommendation based on the 12 statutory factors, including each spouse's income, health, and employability.
Does alimony end when my ex remarries in Colorado?
Yes. Colorado maintenance terminates automatically upon the recipient's remarriage or entry into a civil union under C.R.S. § 14-10-122. The paying spouse does not need to file a motion to stop payments. If the remarriage is later annulled, the court may reinstate the maintenance obligation retroactively.
Can I get permanent alimony in Colorado?
Colorado courts may award indefinite (permanent) maintenance for marriages exceeding 20 years (240 months) under C.R.S. § 14-10-114(3)(b)(II)(C). The court cannot set a term shorter than 120 months for 20+ year marriages without specific findings. Indefinite awards are most common when the recipient's age, health, or work history makes self-sufficiency unlikely.
Does living with a new partner end alimony in Colorado?
No. Colorado does not automatically terminate or reduce spousal maintenance based on cohabitation. Unlike states such as New Jersey, Colorado treats cohabitation differently from remarriage. However, if living with a partner substantially reduces the recipient's expenses, the payor may petition the court for a modification under C.R.S. § 14-10-122.
What happens to alimony if I retire in Colorado?
Colorado law creates a rebuttable presumption that retirement at full Social Security eligibility age (66-67) constitutes good-faith retirement under C.R.S. § 14-10-122. Retirement does not automatically terminate alimony. The retiring spouse must file a modification motion, and the court will evaluate retirement income, Social Security benefits, and both parties' financial needs.
Is Colorado alimony taxable?
No. Since January 1, 2019, Colorado spousal maintenance is non-taxable to the recipient and non-deductible for the payor. Colorado adjusted its advisory formula through HB18-1385 to account for this federal tax change by applying multipliers of 80% (combined income under $10,000/month) or 75% (combined income $10,001-$20,000/month) to the base calculation.
What income cap applies to Colorado's alimony formula?
Colorado's advisory maintenance formula applies only when the parties' combined adjusted gross income is $240,000 per year or less ($20,000 per month) under C.R.S. § 14-10-114. When combined income exceeds $240,000, the court has full discretion over both the amount and duration of maintenance with no formula guidance.
Can a Colorado alimony order be made non-modifiable?
Yes. Colorado allows parties to agree that maintenance is non-modifiable in their separation agreement under C.R.S. § 14-10-122. A non-modifiable order cannot be changed regardless of how dramatically either party's circumstances change. Courts will enforce non-modifiable terms as written, making this decision one of the most consequential in any Colorado divorce negotiation.
How long does it take to get divorced in Colorado?
Colorado imposes a mandatory 91-day waiting period under C.R.S. § 14-10-106 that cannot be waived by the court or parties. The clock starts when the respondent is served or when both spouses file a co-petition. Uncontested divorces typically finalize in 3-4 months. Contested divorces with maintenance disputes average 9-18 months.
Does Colorado consider fault when awarding alimony?
No. Colorado is a pure no-fault divorce state. The sole ground for divorce is that the marriage is irretrievably broken under C.R.S. § 14-10-106. Adultery, cruelty, abandonment, and other marital misconduct cannot increase or decrease a Colorado maintenance award. Courts focus exclusively on financial factors and the 12 criteria in C.R.S. § 14-10-114.
