Yes, alimony (called spousal maintenance in Colorado) can be changed under C.R.S. § 14-10-122. Colorado courts will modify maintenance when there is a substantial and continuing change in circumstances that makes the original order unfair. The filing fee for a post-decree modification motion is $105 as of March 2026. Common grounds include income changes of 10% or more, retirement at Social Security full retirement age (66-67 depending on birth year), cohabitation that reduces the recipient's financial need, or significant health changes. However, if your separation agreement states maintenance is non-modifiable, modification is not available regardless of circumstances.

Understanding Colorado's Alimony Modification Standard
Colorado uses a two-part test for alimony modification under C.R.S. § 14-10-122(1)(a): the change must be both substantial and continuing, and it must make the original terms unfair. A 5% income reduction from $20,000 per month to $19,000 per month likely fails the substantial test, while a 20% reduction almost certainly qualifies. Temporary changes such as brief unemployment do not meet the continuing requirement. Colorado courts examine the totality of circumstances, including financial factors like income changes and non-financial factors like health status and cohabitation. The burden of proof falls on the party requesting the modification to demonstrate that circumstances have changed sufficiently to warrant court intervention.
Grounds for Increasing Spousal Maintenance
Colorado courts may increase alimony when the recipient spouse demonstrates a substantial decrease in their earning capacity or an increase in legitimate financial needs. Under C.R.S. § 14-10-122, qualifying grounds include the recipient developing a serious medical condition that prevents employment, the payor spouse receiving a significant income increase (typically 10% or more), unexpected increases in the cost of living, or the recipient being unable to achieve financial independence despite good-faith efforts. The court considers whether the original maintenance order contemplated the recipient becoming self-supporting within a specific timeframe and whether that goal has become impossible due to circumstances beyond the recipient's control. Inflation alone is generally insufficient, but combined with other factors, it may support an increase.
Grounds for Reducing Spousal Maintenance
The paying spouse may seek to reduce alimony in Colorado based on several recognized grounds under C.R.S. § 14-10-122. Job loss or significant income reduction of 10% or more is the most common basis, though the change must be involuntary and not self-induced. Retirement at full Social Security age (currently 66 for those born 1943-1954, increasing to 67 for those born 1960 or later) creates a rebuttable presumption of good faith retirement under C.R.S. § 14-10-122(2)(c). The recipient spouse's cohabitation with a romantic partner that significantly reduces their financial need may justify reduction. Additionally, if the recipient spouse's income increases substantially, the payor may argue the original award is now unfair. Courts will also consider the payor spouse's involuntary disability or health decline that limits earning capacity.
Terminating Spousal Maintenance Entirely
Colorado law provides for both automatic and court-ordered termination of spousal maintenance. Under C.R.S. § 14-10-122, maintenance automatically ends upon the death of either spouse, the remarriage of the recipient spouse, or the recipient spouse entering a civil union. These termination events require no court action, though the payor should document the triggering event and provide written notice to stop payments. Court-ordered termination requires filing a motion showing that circumstances have changed so substantially that continued maintenance would be unfair. Unlike some states, Colorado does not automatically terminate maintenance upon cohabitation, though cohabitation may reduce the recipient's financial need enough to justify termination. The court examines whether the recipient has achieved self-sufficiency or whether continued maintenance serves no reasonable purpose.
Cohabitation and Its Impact on Colorado Alimony
Colorado takes a nuanced approach to cohabitation that differs from states with automatic termination provisions. The Colorado legislature explicitly rejected making cohabitation an automatic trigger for maintenance termination. Instead, under C.R.S. § 14-10-122, cohabitation serves as potential grounds for modification or termination only if the payor can prove it has significantly reduced the recipient's financial need. Evidence must demonstrate that the cohabiting partner contributes to the recipient's household expenses, shares financial responsibilities, or otherwise improves the recipient's economic situation. Courts examine factors such as shared rent or mortgage payments, combined grocery expenses, joint utility accounts, or other financial interdependence. The recipient's mere romantic involvement or the partner occasionally staying overnight is insufficient. The cohabitation must have a measurable financial impact on the recipient's need for continued support.
Retirement and Maintenance Modification
Colorado law specifically addresses retirement as grounds for alimony modification under C.R.S. § 14-10-122(2)(c). The statute creates a rebuttable presumption that retirement is in good faith when the payor spouse reaches the age for full United States Social Security benefits. This age is currently 66 for individuals born between 1943 and 1954, increasing by two months per year to reach 67 for those born in 1960 or later. The good-faith presumption means the burden shifts to the recipient to prove the retirement was intended to avoid maintenance obligations. However, early retirement before reaching full Social Security age receives no presumption, and the payor must affirmatively demonstrate the retirement was made in good faith and not to evade support obligations. Courts consider factors such as industry norms, health conditions, employer policies, and whether the payor has retirement assets sufficient to continue payments.
Non-Modifiable Maintenance Agreements
When spouses negotiate maintenance as part of a separation agreement rather than having a judge determine the award, they may agree that maintenance is non-modifiable. Under C.R.S. § 14-10-122, if the separation agreement explicitly states that maintenance is contractual and non-modifiable, the court cannot modify the terms regardless of subsequent circumstances. This provision means that even catastrophic changes such as total disability, complete loss of income, or the recipient winning the lottery will not permit modification. Courts interpret non-modifiability clauses strictly. Language must clearly and unambiguously waive the right to seek modification. Phrases like parties intend this to be the final agreement on maintenance or maintenance is not subject to modification meet the standard. However, if the agreement is silent on modifiability, Colorado courts presume the maintenance award is modifiable. Parties should carefully consider the implications before agreeing to non-modifiable terms.
The SB25-116 Domestic Violence Factor (Effective August 2025)
Colorado significantly expanded maintenance considerations through Senate Bill 25-116, signed May 19, 2025, and effective August 6, 2025. The law added domestic violence as the 16th statutory factor courts must consider in maintenance determinations. Under this amendment, courts must now consider whether either spouse has engaged in domestic violence, coercive control, economic abuse, litigation abuse, emotional abuse, physical abuse, or unlawful sexual behavior as defined in C.R.S. § 18-6-800.3. This applies to an estimated 15-30% of Colorado divorces involving domestic violence. The law aims to prevent abusers from receiving maintenance funded by their victims and may strengthen victims' positions when seeking maintenance increases or arguing against paying support to an abuser. The disclosure period for protection orders extended from 2 years to 5 years prior to filing.
How to File for Alimony Modification in Colorado
Filing for alimony modification in Colorado requires submitting a motion to the District Court that issued the original divorce decree. The filing fee is $105 as of March 2026, though fee waivers are available for those demonstrating financial hardship. You can file online through Colorado Courts E-Filing or in person at the court clerk's office. Required documents typically include the Motion to Modify Spousal Maintenance (JDF 1417), a completed Sworn Financial Statement (JDF 1111), and supporting documentation of changed circumstances such as pay stubs, tax returns, medical records, or evidence of cohabitation. You must serve the opposing party with copies of all filed documents. After filing, the court will schedule a hearing where both parties can present evidence. The modification becomes effective retroactive to the filing date unless the court finds this would cause undue hardship or substantial injustice under C.R.S. § 14-10-122(1)(d).
Evidence Required for Modification
Successful alimony modification in Colorado requires compelling evidence that circumstances have changed substantially. Financial documentation forms the foundation of most modification cases. The moving party should gather recent pay stubs covering at least 3-6 months, the most recent 2-3 years of federal and state tax returns, current bank statements, documentation of any job loss including termination letters and unemployment benefits, medical records if health has changed, proof of retirement including pension statements and Social Security determinations, and evidence of the recipient's cohabitation such as social media posts, utility bills, or witness statements. For income reductions, courts expect evidence that the loss was involuntary. Voluntary actions like quitting a high-paying job to pursue a passion project typically do not support modification. The evidence must demonstrate both the substantial nature of the change and its continuing or permanent character.
Timeline for Modification Proceedings
Alimony modification cases in Colorado typically resolve within 3-6 months from filing to final order, though contested cases may take longer. After filing the motion ($105 fee), you must serve the other party within 91 days. The respondent has 21 days to file a response. The court then schedules an initial status conference, typically within 30-45 days. Discovery and financial disclosure usually require 30-60 days. If parties cannot settle, a hearing is scheduled, typically within 60-90 days of the status conference. The judge or magistrate issues a written order following the hearing. Any modification is effective retroactive to the date the motion was filed under C.R.S. § 14-10-122(1)(d), meaning you may be entitled to a credit or may owe arrears from the filing date. Complex cases involving disputes over income, business valuations, or credibility issues may extend the timeline to 9-12 months.
Cost of Modifying Alimony in Colorado
The cost to modify alimony in Colorado ranges from $105 (filing fee only for self-represented parties) to $5,000-15,000 or more for attorney representation in contested cases. The breakdown includes the $105 court filing fee, service of process fees of $25-75, and potential costs for financial experts if income is disputed ($500-2,000). Attorney fees vary significantly based on case complexity. Simple agreed modifications may cost $500-1,500 in attorney fees, while fully contested modifications requiring discovery, expert witnesses, and a hearing may cost $5,000-15,000 or more. Fee waivers are available for those who qualify based on income. Colorado courts may award attorney fees to either party under C.R.S. § 14-10-119 if the other party's conduct was frivolous, substantially groundless, or brought in bad faith. Some attorneys offer limited-scope representation for specific tasks rather than full case handling.
Comparing Contested vs. Uncontested Modification
| Factor | Uncontested Modification | Contested Modification |
|---|---|---|
| Timeline | 4-8 weeks | 3-12 months |
| Attorney Fees | $500-1,500 | $5,000-15,000+ |
| Court Appearances | Often none (stipulation filed) | Multiple hearings possible |
| Evidence Required | Minimal (parties agree) | Extensive documentation needed |
| Stress Level | Low | High |
| Outcome Predictability | High (agreed terms) | Variable (judge decides) |
| Best For | Cooperative former spouses | Disputes over facts or fairness |
Uncontested modifications occur when both parties agree on the new maintenance terms. They file a stipulated modification that the court typically approves without a hearing. Contested modifications require each party to present evidence and arguments, with the judge making the final decision based on the substantial and continuing change standard under C.R.S. § 14-10-122.
What Courts Consider in Modification Decisions
Colorado courts apply 16 statutory factors when evaluating maintenance modification requests under C.R.S. § 14-10-114 and C.R.S. § 14-10-122. These include the financial resources of both parties, each party's reasonable needs, the marital standard of living, the distribution of property in the divorce, each party's current and potential income, changes in employment circumstances, the ages and health of both parties, the recipient's educational history and time needed to acquire sufficient education or training, the historical contributions of each party to the marriage, and whether either party has engaged in domestic violence (added by SB25-116 effective August 2025). Courts weigh these factors against the original circumstances to determine whether a modification is warranted. No single factor is determinative, and judges have significant discretion in balancing competing considerations.
Common Mistakes to Avoid
Parties seeking alimony modification in Colorado frequently make preventable errors that undermine their cases. Filing too soon after a temporary setback, such as a brief period of unemployment, fails the continuing requirement under C.R.S. § 14-10-122. Stopping payments without a court order exposes the payor to contempt charges and arrears accumulation. Voluntarily reducing income by quitting a job or turning down promotions typically backfires, as courts may impute income based on earning capacity. Failing to gather sufficient documentation leaves parties unable to prove their claims. Ignoring non-modifiability clauses in separation agreements wastes time and money on motions the court cannot grant. Waiting too long to file means accumulating unnecessary payments or struggling without needed increases. Not disclosing all assets and income on the Sworn Financial Statement can result in sanctions or denial of the modification. Attempting complex modifications without legal counsel often results in unfavorable outcomes.
