Long-Term Marriage Divorce in Colorado

Why the maintenance term table ends at twenty years, and what the court weighs after that

Colorado’s advisory maintenance guidelines include a term table, and that table ends at twenty years. It covers marriages of at least three years but not more than twenty, so past twenty years it no longer supplies a number.

The rest of the framework does not disappear. The court still runs the statutory maintenance analysis and still weighs the statutory factors, and there is a floor it cannot drop below without explaining itself.

What changes is that the term stops being a calculation and becomes a judgment call. That judgment rests on what the record shows about two financial lives that merged decades ago.

The same thing happens on the property side. After twenty or thirty years, tracing what was separate and what became marital is usually harder than deciding how to divide it.

What Counts as a Long-Term Marriage in Colorado

Colorado does not define the phrase anywhere in statute. The maintenance guidelines create the practical dividing lines, and there are two worth knowing.

Twelve and a half years. This is where the guideline term multiplier stops climbing. Below it, a longer marriage produces a proportionally longer term; above it, the percentage flattens out.
Twenty years. The guideline term table covers marriages of at least three years but not more than twenty. Past that point the table stops, and the statute hands the question to the court.

Most people arriving at this page are somewhere past the second line. The cases are often called gray divorces, though the label is about age rather than marriage length, and the two do not always overlap.

What makes them distinct is not conflict or complexity for its own sake. It is that the ordinary Colorado divorce framework leans on tables and presumptions calibrated to shorter marriages. Several of them stop giving answers right where these cases begin.

Where the Maintenance Term Table Ends

C.R.S. 14-10-114 ^[1] sets out advisory guidelines that apply where the marriage lasted at least three years. The guidelines have two separate parts, and they do not have identical applicability.

The guideline amount is calculated by formula and is tied to the parties’ combined adjusted gross income, with the statute setting out thresholds that determine which calculation applies.
The guideline term comes from a table covering marriages of at least three years but not more than twenty years, expressed as a percentage of the length of the marriage.

That distinction matters in a long-marriage case, because the two can behave differently on the same set of facts ^[2]. What ends at twenty years is the term table, not the maintenance analysis. When the marriage exceeds twenty years, the statute says something different about the term. The court may award maintenance for a specified term of years or for an indefinite term. Read that carefully, because it is routinely overstated. Indefinite is one option available to the court, not a default and not a guarantee.

The floor the court cannot drop below without findings

There is a real constraint built into the same provision. For a marriage longer than twenty years, the court cannot go below the guideline term for a twenty-year marriage without making specific findings supporting the reduction. It is worth knowing what that number is. The table caps the multiplier at fifty percent, so a twenty-year marriage produces a guideline term of one hundred twenty months, or ten years. Ten years is therefore the practical floor in a long-marriage case. A shorter award is possible, but only with findings on the record that explain it. That findings requirement is the most useful thing to understand about these cases. It does not fix an outcome, but it means a shorter award has to be explained on the record rather than simply chosen. The amount calculation runs on its own formula and its own income thresholds, covered in depth on our Colorado alimony page. This page is about what changes when the marriage is long.

What the Court Weighs Once the Formula Stops

The statutory factors do not disappear when the table does. They become the whole analysis, and the court must make findings supporting the amount and term it orders.

Each spouse’s financial resources, including the marital property each will receive and the ability to meet reasonable needs independently.
The standard of living during the marriage, which after several decades is a long and well-documented record rather than a recent snapshot.
Earning capacity and employability, including the effect of years spent out of the workforce and the realistic prospects of a spouse re-entering it in their late fifties or sixties.
Contributions to the marriage, including contribution as a homemaker and support of the other spouse’s career or education.
Age and health of both spouses, which in a long-marriage case frequently drives the analysis more than income does.

Notice what these have in common. Each one rewards documentation covering years, not months, which is the opposite of how most people prepare for a divorce.

Abuse is now a named maintenance factor

Colorado added this in 2025. Senate Bill 25-116 amended the maintenance statute to direct the court to consider whether a spouse engaged in abuse against the other spouse ^[3]. The named categories are domestic violence, coercive control, economic abuse, litigation abuse, emotional abuse, physical abuse, and unlawful sexual behavior. Economic abuse is the version that shows up most often in long marriages, and Colorado now defines it in the statute. The definition reaches restricting a spouse’s access to money, assets, credit, or financial information, using their credit or property without authorization, and exerting undue influence over their financial decisions. It also covers causing or attempting to cause a spouse to become financially dependent by maintaining control over their financial resources. That is a recognizable pattern in a marriage where one spouse handled everything for thirty years. A second act sharpened the surrounding definitions. House Bill 26-1309 took effect on May 27, 2026 and amended C.R.S. 14-10-103 to set out expanded definitions of domestic violence and coercive control for Article 10 ^[4]. Those definitions reach conduct whether or not it was ever charged as a crime. So the definitions live in one statute and the maintenance factor lives in another. The court applies the maintenance statute, which requires it to consider whether a spouse engaged in the listed conduct, and the defined terms supply the meaning. Senate Bill 25-116 also extended the disclosure duty at filing. A party must now disclose qualifying prior protection orders entered within five years before the petition rather than two. Colorado has amended this area in each of the last two sessions. Guidance written even a year ago may describe a version of the statute that no longer applies ^[5].

Wondering What the Guideline Would Even Produce in Your Case?

Past twenty years the term table gives no answer, and the guideline amount is only ever a starting point. That combination makes online calculators close to useless in these cases.

What matters is which facts your record can actually support.

One conversation is usually enough to map the realistic range and identify the documents worth gathering first. You can reach our Colorado divorce team to talk through where your case stands.

Decades of Commingling Make Property Division the Larger Fight

Colorado divides marital property equitably, which means fairly rather than automatically in half. In a long marriage the harder question comes earlier, at classification. Property acquired during the marriage is presumed marital regardless of whose name is on it. Separate property is a narrow exception, and the spouse claiming it carries the burden of proving it. One rule does most of the damage to expectations. An asset owned before the marriage generally stays separate only up to its value at the time of the marriage. The increase in value during the marriage is generally treated as marital property. That is the basic rule, not the whole analysis. Classification still depends on the statutory definitions and exceptions, and how the asset was treated during the marriage can change the answer. Over thirty years that appreciation frequently exceeds the original value several times over. Proving the original number is the whole game, and our page on marital versus separate property walks through what that proof actually looks like. Long marriages also produce specific traps that shorter ones do not.

Records that no longer exist. Statements showing what an account or home was worth in 1994 are often gone, and reconstructing that value can require an expert.
Assets that changed form. A premarital asset sold and reinvested can keep its separate character if the funds are traced, though tracing alone does not always settle it. Commingling, gifts between spouses, and how the parties treated the asset all matter.
Inheritances absorbed into the household. Money that stayed in a separate account is treated differently than money that went into the joint mortgage.
Debt built up over decades, which is divided along with the assets and is frequently the part people forget to inventory.

How Colorado approaches the division itself, once classification is settled, is covered on our Colorado property division page.

Retirement Assets Are Usually the Largest Item on the Table

In most long-marriage divorces the retirement accounts are worth more than the house. They are also the item people most often misunderstand. Retirement interests are classified and divided as property rather than awarded as maintenance. The portion earned during the marriage is generally marital and subject to equitable division, even though only one spouse’s name is on the account. That does not put them outside the maintenance analysis entirely. Retirement assets and the income they produce are financial resources, and the court weighs each spouse’s resources when deciding maintenance. Dividing an employer plan may require a qualified domestic relations order or another plan-specific order in addition to the decree. The timing and the procedure depend on the type of plan. The practical point is that a decree saying an account will be split does not always move the money by itself. Confirm what your particular plan requires before you assume the division is finished.

Defined benefit pensions require valuation, and the present value depends on assumptions about retirement age, mortality, and discount rate that reasonable experts dispute.
Public employee plans follow their own division procedures rather than the private-sector process, so the mechanics differ.
Military and federal benefits are governed partly by federal rules layered on top of the Colorado division.

Some benefits are governed outside your decree. Social Security eligibility based on a former spouse’s earnings record is administered by the Social Security Administration rather than decided by a Colorado judge. Continuation of health coverage after divorce may fall under federal rules with their own deadlines, though not every situation is covered by the same regime. Neither issue is outside the settlement conversation, because both affect what a realistic post-divorce budget looks like. Both are worth confirming before you sign anything. A decree cannot rewrite a federal eligibility rule, but knowing the rule changes what terms make sense.

What Happens to Maintenance Later

A long-marriage award is not necessarily the last word. Unless the order states that maintenance is non-modifiable, either party can ask the court to change it by showing a substantial and continuing change in circumstances. Retirement is the obvious example, and it is foreseeable in a way most changes are not. A paying spouse who expects to retire in six years is usually better served addressing it in the original order than litigating it later. Colorado law also sets default endpoints. Maintenance ordinarily terminates on the death of either party and on the remarriage of the recipient, unless the decree or a written agreement provides otherwise. The statute addresses establishment of a civil union as well.

The remarriage question is unsettled right now

How explicit a written agreement has to be in order to override the automatic termination on remarriage is genuinely contested in Colorado. Appellate panels have applied different standards over the years, ranging from a requirement of express remarriage language to a looser test allowing continuation by clear implication. The Court of Appeals addressed the question in In re Marriage of Clark in August 2025. The Colorado Supreme Court then agreed in May 2026 to review it and settle the standard. Until that decision issues, the safe course is not to rely on general language. If you intend maintenance to survive a remarriage, say so directly in the agreement rather than relying on a clause stating that maintenance cannot be modified or terminated. Those are two different ideas, and courts have split on whether one covers the other.

Mistakes That Cost Ground in Long-Marriage Divorces

These cases fail in predictable ways, and most of the failures happen before anyone files.

Assuming twenty years means permanent maintenance. The statute gives the court an option, not a rule. The reliable figure is the ten-year floor, not an indefinite award.
Trading the house for the retirement accounts. A house and an account of equal stated value are not equal after taxes, carrying costs, and liquidity are accounted for.
Not looking for the old records. The document proving what a premarital asset was worth decades ago is often still findable, but not after the case has moved on.
Underestimating the standard-of-living record. Years of household spending is evidence, and the spouse who can document it is arguing from facts rather than impressions.
Treating a financial-abuse history as background. Since 2025 it is a statutory maintenance factor, and it needs to be presented as evidence rather than as context.

How Johnson Law Group Handles Long-Term Marriage Divorce

We start by figuring out what the record can prove about a financial history that spans decades. In these cases the constraint is almost never the law, it is the documentation. From there the work follows a consistent sequence:

Reconstruct the timeline. Values at the date of marriage, the path of every asset that changed form, and where separate money crossed into marital use.
Build the factor record. Standard of living, earning capacity, health, and contribution, organized against the statutory factors the court has to make findings on.
Model the retirement split properly. Valuation, tax character, and the separate orders needed to actually divide a plan after the decree enters.
Address abuse history as evidence. Where economic abuse or coercive control is part of the marriage, it is now a named factor and belongs in the presentation.
Plan for the years after the decree. Retirement, modification language, remarriage terms, and survivorship provisions decided now instead of relitigated later.

We will not promise a particular ruling, and we will tell you plainly when an expectation is unrealistic. What you get instead is a clear read on what your marriage actually looks like on paper and a plan built to match it. Across our five Colorado offices, that steadiness is what we mean when we describe ourselves as your North Star.

Frequently Asked Questions

What counts as a long-term marriage in Colorado?

Colorado does not define the phrase, but the maintenance statute creates a practical dividing line. The advisory guideline term table covers marriages of at least three years but not more than twenty years.

Once a marriage passes twenty years the table no longer supplies a term, and the court moves into a different analysis. Twelve and a half years matters too, because that is where the term multiplier stops climbing.

Is spousal maintenance permanent after a twenty-year marriage in Colorado?

Not automatically, and this is widely misstated. When a marriage exceeds twenty years the statute says the court may award maintenance for a specified term of years or for an indefinite term.

Indefinite is one option the court has, not a default outcome. An indefinite award is also still subject to the statutory rules on modification and termination.

Can a Colorado court order less maintenance than the twenty-year guideline term?

It can, but not casually. For a marriage longer than twenty years Colorado’s guideline term is ten years, because the table caps the multiplier at fifty percent of a twenty-year marriage.

A court may order a shorter term only if it makes specific findings supporting the reduction. That findings requirement is the practical floor, and it is why the evidentiary record matters so much.

How is a pension or retirement account divided after a long marriage?

Retirement interests are classified and divided as property rather than awarded as maintenance, though the assets and the income they produce still count as financial resources in the maintenance analysis. The portion earned during the marriage is generally marital property subject to equitable division.

Dividing an employer plan may require a qualified domestic relations order or another plan-specific order in addition to the decree, depending on the plan type. Valuation is often the real dispute, particularly for defined benefit pensions where present value depends on contested assumptions.

I owned our house before we married thirty years ago. Is it still separate property?

The value it had on your wedding day generally remains separate, but the increase in value during the marriage is treated as marital property. Over a long marriage the appreciation frequently dwarfs the original value.

You also carry the burden of proving the separate portion. That requires documentation of what the asset was worth back then, which is the part most people cannot produce.

Does abuse affect spousal maintenance in Colorado?

Yes. Since August 2025 the maintenance statute directs the court to consider whether a spouse engaged in abuse against the other spouse. The named categories are domestic violence, coercive control, economic abuse, litigation abuse, emotional abuse, physical abuse, and unlawful sexual behavior.

Colorado law now also supplies detailed statutory definitions of these terms that apply across dissolution cases. Economic abuse includes patterns like controlling a spouse’s access to money, credit, and financial information.

What happens to maintenance when the paying spouse retires?

Retirement does not automatically terminate an award. Unless the order or agreement makes maintenance non-modifiable, changing it requires going back to court and showing changed circumstances so substantial and continuing as to make the existing terms unfair.

Because retirement is foreseeable in a long-marriage case, it is worth addressing in the original order rather than leaving it to a future motion.

Does maintenance end if I remarry?

The statutory default is that maintenance terminates on the recipient’s remarriage, and on the death of either party, unless the decree or a written agreement provides otherwise. The statute addresses establishment of a civil union as well.

How explicit that written agreement has to be is currently before the Colorado Supreme Court, which took up In re Marriage of Clark in May 2026. Until it rules, do not rely on a general clause saying maintenance cannot be modified or terminated. Say expressly whether maintenance continues after a remarriage.
