Lump sum alimony in Colorado replaces ongoing monthly spousal maintenance with a single up-front payment or property transfer, creating a clean financial break. Colorado courts approve lump sum alimony when parties agree or facts justify it under Colo. Rev. Stat. § 14-10-114. The payment is discounted to present value, and unlike monthly support, a buyout is generally non-modifiable once finalized.

What Is Lump Sum Alimony in Colorado?
Lump sum alimony in Colorado is a one-time alimony payment that discharges a spouse's entire maintenance obligation in a single transaction instead of monthly installments. Colorado law does not list lump sum maintenance as a separate statutory category, but courts approve it under C.R.S. § 14-10-114 when parties agree or facts justify a buyout. The payment is typically discounted to present value because money received today is worth more than the same total paid over 10 years.
Colorado recognizes three buyout structures. A cash lump sum transfers a fixed dollar amount at the time of the decree. A property offset gives the receiving spouse a larger share of marital assets — such as the family home or a retirement account — in place of monthly support. A hybrid arrangement combines a partial lump sum with reduced periodic payments. Each structure ends the continuing payor-payee relationship, which is the central appeal of a one time alimony payment. Roughly 60 percent of negotiated maintenance buyouts in practice use a cash or property offset rather than a hybrid, because spouses seeking a buyout usually want complete finality.
How Colorado Calculates the Maintenance That a Buyout Replaces
Colorado's advisory maintenance formula under C.R.S. § 14-10-114 applies only when the marriage lasted 3 to 20 years and combined annual adjusted gross income is $240,000 or less. The base amount equals 40 percent of the higher earner's gross monthly income minus 50 percent of the lower earner's, capped at 40 percent of combined income. A lump sum buyout is calculated by valuing this stream of payments, then discounting to present value.
The statute applies an income multiplier reflecting the 2019 federal tax change that ended the alimony deduction. An 80 percent multiplier applies when combined monthly income is $10,000 or less, dropping to 75 percent for combined income between $10,001 and $20,000. For example, if Spouse A earns $10,000 monthly and Spouse B earns $3,000, the calculation is $4,000 (40 percent of $10,000) minus $1,500 (50 percent of $3,000), producing an advisory maintenance amount of approximately $1,875 per month after the multiplier. The duration formula sets the term at 31 percent of marriage length in months at the 36-month mark, rising to 50 percent at 150 months (12.5 years). A 10-year marriage yields roughly 4 to 5 years of payments — the figure a buyout converts into one number.
How a Colorado Alimony Buyout Is Valued
An alimony buyout in Colorado converts the projected monthly maintenance stream into a single present-value figure, then discounts it because immediate cash exceeds the value of deferred payments. A 5-year maintenance award of $1,875 per month totals $112,500 in gross payments, but a buyout typically settles below that — often 80 to 92 percent — to reflect time value of money and the elimination of non-payment risk. The exact discount rate is negotiated, not set by statute.
Three variables drive the buyout number. First, the monthly maintenance amount under the C.R.S. § 14-10-114 advisory formula sets the baseline. Second, the duration — tied to marriage length — determines how many payments are bought out. Third, the discount rate (commonly 2 to 5 percent for present-value calculations) reduces the gross total. Because lump sum vs monthly alimony involves real tax and risk trade-offs, many couples retain a financial professional or use a present-value calculator. The receiving spouse trades a small discount for guaranteed payment and freedom from a payor who could lose income, fall behind, or die before completing a multi-year obligation.
Lump Sum vs Monthly Alimony: A Direct Comparison
Lump sum alimony delivers certainty and a clean break, while monthly maintenance preserves flexibility and spreads tax and cash-flow impact. The right choice depends on the payor's available capital, the recipient's need for guaranteed support, and each party's appetite for future risk. The table below compares the two structures across the factors Colorado spouses weigh most heavily.
| Factor | Lump Sum Buyout | Monthly Maintenance |
|---|---|---|
| Modifiability | Generally non-modifiable once paid | Modifiable on substantial change (C.R.S. § 14-10-122) |
| Payment risk | Zero — paid up front | Risk of non-payment over years |
| Total cost | Discounted 8–20% below gross stream | Full undiscounted amount |
| Cash required | Large up-front capital needed | Spread over months or years |
| Finality | Ends payor-payee relationship | Ongoing relationship and review |
| Termination on remarriage | Not affected — already paid | Terminates on recipient remarriage |
A lump sum buyout suits a payor with liquid assets who wants to close the financial relationship, and a recipient who values guaranteed money over potentially higher long-term totals. Monthly maintenance suits a payor without large reserves and situations where future circumstances may change. Colorado law lets parties choose either, or a hybrid, through a written separation agreement.
Non-Modifiability: The Central Advantage of a Buyout
A Colorado alimony buyout is generally non-modifiable because once the lump sum is paid, the maintenance obligation is satisfied and there is nothing left to modify. By contrast, ordinary monthly maintenance remains modifiable under C.R.S. § 14-10-122 whenever a party shows a substantial and continuing change in circumstances that makes the original order unfair. This permanence is the defining feature that distinguishes a one-time payment from ongoing support.
Colorado courts cannot impose non-modifiable periodic maintenance on their own, but parties can agree to it in writing. An alimony buyout agreement that designates the payment as non-modifiable must be explicit and in writing, and the court will sign it into the decree. If a property settlement is used instead of maintenance, that transfer is generally non-modifiable by default, because property division under C.R.S. § 14-10-113 is final once the decree enters. This is why structuring support as a property offset or lump sum buyout provides more finality than periodic payments. The trade-off is rigidity: a buyout cannot adjust if the payor later loses income or the recipient becomes unable to work, so both sides accept that risk in exchange for certainty.
Tax Treatment of Lump Sum Alimony in Colorado
For any Colorado maintenance order entered after December 31, 2018, the payment is not deductible by the payor and not taxable income to the recipient under federal law. This applies equally to a lump sum alimony payment and to monthly maintenance, because the 2017 Tax Cuts and Jobs Act eliminated the alimony deduction for all orders after that date. Colorado has not enacted separate tax treatment, so the federal rule controls.
The end of the deduction reshaped how Colorado spouses structure buyouts. Before 2019, a payor could deduct maintenance, making large monthly awards cheaper after tax. Now that no deduction exists, many couples negotiate a property settlement in lieu of maintenance, transferring assets such as home equity or retirement accounts rather than paying taxable-history support. A property transfer incident to divorce is generally not a taxable event under federal law, which can produce a better after-tax result than either monthly maintenance or a cash buyout. The advisory formula's 75 to 80 percent multiplier in C.R.S. § 14-10-114 already reduces guideline awards to account for this lost deduction, so the maintenance figure a buyout replaces is itself smaller than pre-2019 awards.
Filing Costs and Timeline for a Colorado Divorce With a Buyout
Filing a dissolution of marriage in Colorado costs a $230 base fee plus a $12 non-waivable e-filing fee, with the responding spouse paying $116 (as of March 2026 — verify with your local clerk). These fees rose statewide on January 1, 2025, under Colorado House Bill 2024-1286. You file the Petition for Dissolution of Marriage with the District Court in the county where either spouse resides, in person or through the Colorado Courts E-Filing System.
Colorado imposes a dual 91-day structure. At least one spouse must have lived in Colorado for 91 days before filing under C.R.S. § 14-10-106, and a separate 91-day waiting period runs from service of the petition or the joint filing date before any decree can enter. This waiting period cannot be waived, even in fully agreed cases. An uncontested dissolution that includes a lump sum buyout typically finalizes in 3 to 6 months. The fastest path is filing jointly as co-petitioners with a complete separation agreement covering property, the maintenance buyout, and parenting time, which starts the 91-day clock immediately and avoids service delays. Additional costs include process servers ($50–$100), parenting classes ($25–$55), and mediation ($500–$3,000). Fee waivers are available through forms JDF 205 and JDF 206 for those who cannot afford the filing fee.
When a Lump Sum Buyout Makes Sense in Colorado
A lump sum alimony buyout makes the most sense in Colorado when the paying spouse holds liquid assets and both parties want to end their financial relationship permanently. Courts and practitioners see buyouts most often in marriages of 3 to 20 years where the advisory formula produces a clear maintenance figure that can be reliably converted to present value. The structure rewards finality over flexibility.
Several fact patterns favor a buyout. A self-employed or high-net-worth payor may prefer a one time alimony payment to avoid years of recurring obligations tied to fluctuating income. A recipient who doubts the payor's reliability gains guaranteed money up front rather than chasing missed payments through enforcement. Couples who want no future contact — a common goal after high-conflict marriages — use the buyout to sever the continuing tie. A buyout is less suitable when the payor lacks the capital to fund it, when future circumstances are highly uncertain, or when the recipient needs the income spread across years for tax or budgeting reasons. Because a buyout is generally irreversible, Colorado practitioners advise running the present-value math carefully and confirming the alimony buyout agreement is drafted as explicitly non-modifiable before signing.
