How Colorado awards spousal support

Our Colorado record classifies it as a discretionary state, which means the court weighs a list of factors and sets an amount it considers fair on the facts in front of it. That is not the same as a statute with no figures in it. C.R.S. § 14-10-114(3)(b), read here on 2026-10-07, lists guidelines that express support as a share of the two spouses' combined adjusted gross income, less the lower earner's, for the amount, and set the term from a table keyed to the length of the marriage. The section sets the amount and the period of support "that is fair and equitable to both parties after considering", and the guideline amount and term are the first of the things it lists, which the section says "do not create a presumptive amount or term of maintenance", so they are something the court weighs rather than a calculation it runs, and this page neither prints them nor applies them. Here is what that looks like in practice.

In a state our record classifies this way, the judge is told what to consider rather than handed an amount to reach. The court weighs the factors against the evidence each side puts up, and the number that comes out is the number that fits those facts in that courtroom. Whether the statute also gives the court figures to take into account is a separate question, and the paragraph above says how far we have read this state's statute to answer it.

That has a consequence worth being honest about: two families with identical finances can walk out with materially different orders, and neither result is wrong. The variation is not a flaw in the approach, it is the approach: the court is given room to fit the order to the case in front of it.

What that means practically is that evidence matters more here than a calculator does. The spouse who can document the marital standard of living, a career interrupted for the household, or a genuine limit on future earning capacity is arguing on the ground the statute actually points the judge toward. Support is also settled by agreement far more often than it is decided at a hearing, so the realistic question is usually what the other side will accept rather than what a judge would impose.

What Colorado courts weigh, in our data's order

These are the 3 factors our Colorado record carries, listed in the order it records them. They are the ground a support argument is actually fought on, so the side that documents them is the side arguing where the statute points.

1. 1Length of the marriageThe strongest single predictor of both how much support is awarded and how long it runs. Short marriages point toward limited, time-boxed support aimed at getting the lower earner back on their feet. Long marriages point toward larger awards over longer terms, and are where indefinite support is still argued for.
2. 2The income difference between the spousesThe figure the calculation is applied to. What matters is the gap, not either income by itself, so a rise in the lower earner's income reduces support just as a fall in the higher earner's does. Two couples with the same household total can reach very different results depending on how that total is split.
3. 3Standard of living during the marriageThe benchmark the court measures need against. It is why the same income gap supports a larger award for a couple who lived expensively than for a couple who saved. Documenting how the household actually spent, through statements rather than recollection, is what makes this factor usable in a hearing.

Does conduct matter in Colorado?

No, and here the statute says so in terms. C.R.S. § 14-10-114(2), read from an Internet Archive capture of content.leg.colorado.gov dated 2026-09-24, says an award of maintenance "shall be made without regard to marital misconduct". Colorado courts work from the incomes, the property each spouse receives, reasonable need and the other listed factors.

Grounds are a separate question from support, and the two do not always line up. Our record has Colorado offering no-fault grounds only, our own record rather than Colorado's own law on divorce grounds, so on our record there is no fault ground to plead in the petition. Conduct is also absent from the support factor list, so for practical purposes who did what is not the argument that decides this case.

Support and the property split are one conversation

Our record has Colorado dividing marital property by equitable distribution, which means the split starts near even and moves with the same kinds of factors that drive support: length of marriage, each spouse's earning capacity, and what each contributed. That is our own record rather than Colorado's own property division law. Because the two questions run on overlapping facts, they are usually negotiated together. Trading a larger share of the estate for a smaller or shorter support award is one of the most common settlement structures there is, and it is often the one that gets a case resolved. Treat this as a planning band, not a prediction. Where the amount is left to the court's weighing of the factors, no calculator can tell you what a particular judge will order. What the estimate is good for is telling you roughly what range the conversation starts in, and which facts move it.

One practical cost sits underneath that trade. Where the asset being swapped for support is a retirement account, dividing it takes a qualified domestic relations order, which runs $600 to $1,800 in Colorado on top of whatever else the case costs. Worth pricing in before you agree to take retirement money instead of monthly support, along with the fact that the two are taxed very differently when you eventually draw on them.

Colorado spousal support examples

These three examples run through the same Colorado calculator on this page, so the figures match what the tool returns for the same entries. Each is a different shape of case rather than a small variation on the one before, because the two things that move support most, the income gap and the length of the marriage, tend to move together in real households.

Read the range, not the single figure inside it. We draw the band deliberately wide here. Open discretion produces a wider spread of real outcomes than a formula does, and a narrow band would misrepresent how much room the court actually has. The width is our judgement about that spread rather than anything the state publishes. In the second example below, the top of the band is about 1.7 times our own estimate inside it.

Set the first and third examples side by side and the scale of what marriage length does becomes clear. The estimate moves from around $560 a month running 0.5 to 2.7 years to around $5,787 a month running 3.2 to 16 years. Part of that is the wider income gap. Most of it is the twenty extra years.

How long spousal support lasts in Colorado

Duration is the question people ask second and worry about first, and it is decided differently from amount. Amount answers what the lower earner needs and what the higher earner can pay. Duration answers a narrower question: how long it should reasonably take the lower earner to get where they can stand on their own, and whether that is realistically possible at all.

The table below runs one couple through the Colorado estimate at seven marriage lengths. Incomes are held at $110,000 and $40,000 a year with no children and no health limits, so the only thing changing between rows is how long the marriage lasted.

Two things are worth reading off that table. The first is that a five-year marriage and a twenty-year marriage are not the same case with a different number attached: at five years the estimate runs 0.7 to 3.3 years and support is only possible, while at twenty years it runs 2.7 to 13.3 years and is very likely. The second is that the ranges stay wide at every length, because duration is where courts exercise the most judgment and where settlements do the most trading.

Support also ends on events, not only on dates. Across states the usual terminating events are the death of either spouse, the recipient remarrying, and in many places the recipient living with a new partner in a marriage-like arrangement. Retirement in good faith at a normal age is the other common ground for cutting support off or reducing it. Whether Colorado treats each of those the same way is a question for a licensed attorney there, and it is worth asking before you sign an agreement rather than after.

How long a case runs in Colorado

Our record has a waiting period of 3 months for Colorado before a divorce can be finalized, and on our own estimates a contested case here runs about 1.1 years, against 4 months when both spouses agree. States start that clock in different places, some at filing, some at service, and some at the date the two of you separated, so check where yours begins. Our record also has 3 months of residency in Colorado before you can file at all.

Data pending verification. Some states cap support duration by statute at a set share of the length of the marriage. We have not verified whether Colorado does, so the duration column above is our general model rather than a Colorado rule, and we are not stating a durational formula we have not checked. Confirm it against the Colorado sources below or with a licensed family law attorney in the state.

The kinds of spousal support a court can order

Support is not one thing. States use different names for the categories below and not every state recognizes all of them, but the underlying purposes are consistent, and knowing which one is being discussed tells you what the argument is really about.

Rehabilitative support

Time-limited support tied to a plan: finishing a degree, renewing a license, completing a training program, or re-entering a field after years away. It is the most common outcome for short and mid-length marriages. Because it is tied to a plan, the strongest version of this request comes with the actual program, its length, and its cost rather than a general statement about needing time.

Durational or term support

A set number of years, usually pegged to the length of the marriage, without needing to be tied to a specific rehabilitation plan. This is the category most reform legislation over the past decade has been about, generally replacing open-ended awards with a term the statute caps.

Indefinite or permanent support

Support with no end date written into it, reserved for long marriages where the age, health, or work history of the lower earner means self-sufficiency is not a realistic outcome. Indefinite does not mean unchangeable: it stays modifiable on a substantial change in circumstances, and it generally ends on the usual terminating events.

Data pending verification. Our Colorado record does not list which of these categories Colorado recognizes by name or what it calls them, so the descriptions above are the general framework rather than a Colorado list. We would rather say that than name four Colorado categories we have not checked.

How spousal support is taxed

This changed in a way that still catches people out. Under the federal Tax Cuts and Jobs Act, for any divorce or separation agreement executed after December 31, 2018, alimony is not deductible by the spouse paying it and is not taxable income to the spouse receiving it. The federal rule is the same in Colorado as everywhere else, because it is federal.

Two consequences follow, and both are worth understanding before you negotiate. Support is now paid out of after-tax dollars, so a given monthly figure costs the payer considerably more than the same figure did before 2019. And the older advice that a large award could be made cheaper by the deduction no longer applies at all. Agreements executed on or before December 31, 2018 generally keep the old treatment, though modifying one can bring it under the current rule if the modification says so.

State income tax is a separate question from the federal one, and it is not something this page models. Check the federal treatment against the IRS guidance below, and check the Colorado treatment with a CPA or a licensed family law attorney in the state.

What it costs to argue about support in Colorado

Support is the issue most likely to turn a divorce contested, and it is also the one where the arithmetic of fighting is easiest to get wrong. Below are the Colorado figures set against what is actually in dispute.

Attorney rate

$250 to $450/hr

Mediation session

$275

Uncontested case

$2,000 to $5,000

Contested case

$14,000 to $42,000

Put those next to the second worked example above, where the estimate came to $1,688 a month, or $20,256 a year. A contested case in Colorado runs $14,000 to $42,000, which is the equivalent of roughly 8 to 25 months of that support. Ten billable hours on each side, which a single contested motion can consume, costs $2,500 to $4,500 per side at Colorado rates. Two mediation sessions cost $550 shared between you.

The sharper way to read those figures is as a difference rather than a total. An uncontested Colorado divorce runs $2,000 to $5,000 and takes 4 months. Contesting it adds $12,000 to $37,000, or roughly 7 to 22 months of the support in that example, and stretches the case to about 1.1 years. That difference is the actual price of the argument, and it is the number to hold against whatever separates your position from your spouse's.

None of that means give up a position worth holding. Where the gap between the two sides is large, where one spouse's income is hard to pin down, or where the marriage was long enough that duration is the real question, representation earns its cost several times over. But where the two positions sit a few hundred dollars a month apart, the arithmetic usually says settle: the fight can cost more than the difference it is about. Our record has Colorado requiring mediation before a contested hearing in any case, so on that record you will be in the room regardless. Going in with your figures already worked out is what makes that session useful rather than a formality. That is our own record rather than Colorado's own court rules. Our record carries collaborative divorce as available in all fifty states, so it says nothing specific about Colorado; whether trained collaborative attorneys practise near you is a local question. Where it is on offer, both sides commit in writing to settle without litigation and share one financial expert instead of hiring two.

Colorado spousal support authority

The part of Colorado's own spousal support law we have read is C.R.S. § 14-10-114 (read from an Internet Archive capture of content.leg.colorado.gov dated 2026-09-24), and what we hold out of it is C.R.S. § 14-10-114(3)(b) and (3)(e), which establishes that the court works out an advisory guideline amount and term where the marriage lasted at least three years and the combined annual adjusted gross income does not exceed $240,000, then sets what is fair and equitable after considering them, and that the guidelines "do not create a presumptive amount or term of maintenance". That reading covers the 2024 edition of the section and not what the 2025 and 2026 sessions did to it. Nothing we hold out of it calculates an award, so the estimate on this page is our own model. Where the statute and this page differ, the statute is right and we are not.

How we calculate this estimate

Alimony is the least formula-driven number in a divorce, and outside one state this estimate is a national approximation rather than any state's own rule. It works from the gap between the two incomes, scaled by how long the marriage lasted, with the share of that gap set by how your state is recorded as deciding support and by the standard of living during the marriage. The other inputs, employment status on both sides, caregiving history, age and health, and marital fault where your state weighs it, move the factors and the likelihood rather than the arithmetic. The output is a monthly range with a duration range, a likelihood rating, and the specific factors pushing your case up or down.

What the estimate assumes for Colorado

• One state's own calculation is implemented, in half. Our record classifies five states as writing a spousal support calculation into their own statute, and the calculation itself has been read for two of them. We run one of those, 750 ILCS 5/504, and the duration our Illinois calculator returns is that statute's arithmetic rather than our model's: the length of the marriage multiplied by a factor the statute fixes for each year of it, wherever the guideline route reaches the case. The Illinois AMOUNT is still ours, because the statute works it out from net annual income and this calculator collects gross. Everywhere else, both figures are the same national approximation. Every alimony figure we return says which of the two it is, beside it.
• The share of the income gap our estimate applies depends on which of three groups our record puts your state in, and the marriage-length factor then multiplies it in every case. A formula state takes 30 percent of the gap, which the factor moves to between 12 and 48 percent of it. A discretionary state takes between 22 and 38 percent depending on the standard of living during the marriage, moving to between 8.8 and 60.8 percent. A hybrid state averages the two, landing between 10.4 and 54.4 percent. Those are the figures before any ceiling a state sets, every one of them is ours, and no state publishes any of them.
• Duration is modeled at about a third of the length of the marriage, with a band around it and a cap at the length of the marriage, in forty-nine states. How wide that band runs depends on the same grouping: a formula or hybrid state gets 20 to 50 percent of the length of the marriage, a discretionary state 13.3 to 66.7 percent. Several of them set duration as a share of the marriage by statute and none of those shares is a third. Illinois is the exception: its ladder runs from .20 below five years to .80 at nineteen and opens up at twenty, we have read it, and our Illinois duration is that calculation rather than the model.
• State limits are applied in five states and shown without being applied in six more. Delaware, Florida, Kansas, Louisiana and Texas each set a ceiling on the amount or the term, we have read that ceiling out of the state's own instrument, and where our arithmetic ran past it the ceiling is what produced the figure. Florida, Louisiana and Texas are the ones whose ceilings are worked on a base the instrument does not use: their rules measure an income this page does not collect, so what we apply is a generous version of the state's own limit, which is why we are willing to bring a figure down to it and never up to it. Each of those pages says so beside the figure. Massachusetts, Maine, New Hampshire and New Jersey's limits are ones a court may go past on a finding (a rebuttable presumption, or a standard such as the interests of justice or exceptional circumstances), so they are shown beside the figure rather than applied to it. Massachusetts, New Hampshire and New Jersey carry second reasons on top of that, set out on their own page beside the figure, and they are the harder of the two: what the rule measures is not what this page collects. Indiana sets its limit flatly for one kind of award among several the statute names, and this page cannot tell which kind a case is, so that limit is shown beside the figure rather than applied to it. Utah has a limit our own page states and nobody here has opened the document behind, so it is worked out on your entries and set beside our estimate without changing it. We do not clamp a number to a figure we could not read. The other 39 states have no limit in our records, which is a statement about our records rather than about their law: where your state limits an amount or a term and we hold nothing for it, the limit still controls and this estimate can exceed it.
• Which of the three approaches a state takes came into our data at the original build. It has since been checked against the state's own rendered instrument in 6 states, Colorado, Florida, Illinois, New Hampshire, New York and Texas, and each of those pages names the instrument that settled it. In the other 44 it is still our record's classification with no statute behind it.
• Fault is only factored in for states where our record says fault can affect a support award.
• The one cost-table figure this page uses is your state's waiting period, and it is our own record rather than a reading of the statute. Nobody here has opened a dissolution statute to check the number, and the same field carries two different things across the fifty states, a wait that runs from filing and a separation requirement that runs from the day you separated. Confirm it with the clerk of court where you will file.
• The estimate is pre-tax. It does not model how support affects either spouse's tax return.

Where the estimate stops

Outside the Illinois duration, this is our model rather than your state's. In a state that publishes its own calculation the number to plan around is that calculation, and a family law attorney licensed there can run it on your figures. Even where a guideline applies, a judge can depart from it and most support terms are negotiated rather than tried, so treat the range as a planning band rather than a prediction of your order.
