In Colorado, the duration of spousal maintenance is typically calculated based strictly on the number of months between the date of marriage and the date of the decree. This creates a significant financial exposure gap for couples with long pre-marital cohabitation periods.
The law that governs this is Colorado Revised Statute 14-10-114, which applies advisory guidelines to determine maintenance terms.
- For marriages lasting between 3 and 20 years, the statute suggests a duration term ranging from 31% to 50% of the marriage’s length.
- Once a marriage crosses the 20-year threshold, however, the court gains broad discretion to award maintenance for an indefinite term.
This statutory structure creates a cliff for LGBTQ+ couples and other long-term partners who may have lived together for decades but only legally married after the 2015 Obergefell v. Hodges Supreme Court decision. A strict reading of the statute might result in a maintenance award of only a few years, despite a relationship that functioned as a marriage for a quarter-century.
To bridge the gap between a short legal marriage and a long-term economic partnership, we must present evidence establishing a common law marriage date that is earlier than the ceremonial marriage or argue for an equitable deviation based on the total relationship duration. At Price Family Law, we review your relationship history and financial data to determine the viable arguments for extending or limiting the maintenance term.

Key Takeaways for Denver Alimony Duration
- The Legal Marriage Date Dictates the Formula: The legal marriage date dictates the formula for alimony duration. This can create an unfair outcome for long-term partners, including same-sex couples, whose relationships predate their legal ability to marry.
- Marriages Over 20 Years May Qualify for Indefinite Alimony: This statutory “cliff” makes the duration of maintenance a fiercely contested issue in high-asset divorces, as the financial stakes are exceptionally high.
- Arguments for a Longer Duration Are Possible: We can argue for a maintenance term that reflects the total length of your economic partnership by establishing an earlier common law marriage date or presenting evidence for an equitable deviation from the guidelines.
The 20-Year Cliff: Why Duration Is the Fiercest Battleground
In Denver high-asset divorces, the monthly amount of alimony is less contested than the duration. The difference between a 5-year term and an indefinite term could amount to hundreds of thousands of dollars over time. This is why the duration fight is so intense.
The statutory cliff in C.R.S. 14-10-114 is the central feature of this battleground. For a 10-year marriage, the guideline term is roughly 4.5 years (45%). For a 20-year marriage, the court may order indefinite maintenance. The key word is may, as the statute is advisory, not mandatory.
This ambiguity is where the legal fight occurs: persuading a judge to deviate from the standard formula based on the specific facts of your case. For high earners, limiting the duration of alimony is the priority over limiting the monthly amount. Do not agree to a maintenance buyout (a lump sum) without first understanding the potential for lifetime exposure.
Same-Sex Spousal Maintenance in Colorado: Bridging the Obergefell Gap
Many same-sex couples in Denver have been partners for 15 years or more but have been legally married for less than 10. This is a direct result of the timing of marriage equality legalization. This discrepancy creates a serious challenge when it comes to calculating spousal support.
Consider this common question: “How long do I have to pay or receive support if we were partners for 15 years but married for only 5?”
Under a strict statutory calculation, a 5-year marriage might yield a maintenance term of roughly 21 months. Yet, from an equitable perspective of a 20-year relationship, the recipient could arguably qualify for support for a much longer term, potentially even indefinitely. This massive disparity creates a volatile negotiation environment where the lower-earning spouse faces a financial cliff.
This is where legal nuance comes in. Colorado is an equitable division state, meaning judges may look beyond rigid formulas to what is fair. A court may consider the economic partnership that existed long before the marriage license was signed. Furthermore, for some couples, time spent in a Colorado Civil Union prior to 2014 could potentially be tacked onto the marriage duration for maintenance calculations.
Strategies for Arguing Total Relationship Duration
Colorado is one of a few states that recognizes common law marriage, which is established by showing that a couple mutually consented and held themselves out to the public as married. To argue for a longer maintenance duration, two key strategies are employed:
- Common Law Marriage Assertion: We will work to retroactively establish a common law marriage date. If you and your partner cohabitated, shared finances, and presented yourselves as a married couple to your community before your legal ceremony, the legal start date of your marriage could be moved back, significantly impacting the duration calculation.
- The Tacking Argument: This strategy argues that the period of pre-marital cohabitation should be tacked onto the legal marriage term for maintenance purposes. While the law looks at the date of marriage, a court’s power to deviate based on unfairness opens the door for arguments about the true length of the economic partnership.
For the spouse seeking maintenance, this means securing recognition for the sacrifices made to their partner’s career during the cohabitation phase. For the paying spouse, it means building a defense by proving there was distinct financial separation before the legal wedding. We gather specific evidence to build these arguments, such as joint tax returns, beneficiary designations, and commingled real estate investments made during the cohabitation period.
FAQ for Spousal Maintenance Duration
What if my spouse remarries before the maintenance term ends?
A person’s obligation to pay future maintenance terminates upon the recipient’s remarriage unless your divorce decree explicitly states otherwise. Disputes arise when agreements are silent on this issue, leading to further litigation.
Does cohabitation affect alimony duration in Colorado?
Unlike remarriage, cohabitation by the receiving spouse does not automatically end maintenance. However, if the cohabitation significantly reduces the recipient’s financial need, the paying spouse may file a motion with the court to modify or terminate the support obligation early.
Can we agree to a non-modifiable duration?
Yes. Parties may agree to contractual maintenance where the amount and duration are fixed and cannot be changed by the court, regardless of future events like job loss or illness. This provides certainty for both sides but also carries significant risk.
How does retirement affect the duration of maintenance?
Retiring at a normal age (such as 65–67) is considered a substantial change in circumstances that justifies a motion to modify or terminate maintenance. However, the termination is not automatic. The court will analyze whether the retirement is taken in good faith and its financial impact.
What if we moved to Colorado recently but lived together in a state that doesn’t recognize common law marriage?
This is a complicated jurisdictional issue. While Colorado recognizes common law marriage, you must have satisfied the requirements while in Colorado or another common-law state. However, equitable arguments regarding the total length of your relationship may still be persuasive to a judge regarding the fairness of the maintenance term.
