How long do you have to be married to get alimony?

Last updated 2026-07-09

Is there a minimum marriage length required to get alimony?

No state sets a strict number of married years that automatically entitles someone to alimony. That surprises people who have heard "you need 10 years" or "you need 7 years." Those numbers circulate as folk wisdom. They are not the law in any state.

Every state does list marriage length as one factor among several a court weighs when deciding whether to award spousal support, how much, and for how long. California Family Code Section 4320 lists "the length of the marriage" as item (f) in a list of fourteen statutory factors ^[1]. Texas is the one real exception. Family Code Section 8.051 sets an actual threshold: spousal maintenance is generally available only after a marriage of ten years or longer, or if domestic violence occurred, or if the spouse seeking support is disabled ^[2]. Most states set no floor at all.

So here is the honest answer. Marriage length matters enormously, but it works as a dial, not a switch. A two-year marriage almost never produces alimony. A twenty-year marriage usually does. Everything in between is a judgment call.

Which states have actual minimum marriage length rules for alimony?

Texas is the clearest state with a codified floor. Under Texas Family Code Section 8.051, a court may award spousal maintenance only if the marriage lasted ten years or more and the spouse seeking support lacks sufficient property to meet minimum reasonable needs, among other conditions ^[2]. Exceptions exist for disability and family violence. The ten-year rule is real and enforced.

Other states use length to control the type or duration of support rather than as a hard eligibility gate.

State	What marriage length controls
Texas	Eligibility: generally requires 10+ years [2]
Florida	Duration: alimony type shifts at 7 and 17 years [3]
California	Duration: courts presume support lasts half the marriage length for marriages under 10 years [1]
Massachusetts	Length informs whether alimony is "general term" vs. shorter-term [4]
New York	Length is one of about 20 statutory factors; no floor [5]
Illinois	Length affects duration caps under IMDMA Section 504 [6]

Florida's 2023 alimony reform law ended permanent alimony. It now sorts marriages as short-term (under 7 years), moderate-term (7 to 17 years), or long-term (17-plus years), with different presumptions for each ^[3]. A 5-year Florida marriage can still produce alimony. The court just presumes a shorter duration.

Illinois ties duration to length by formula. For a 5-year marriage, support runs 20% of the marriage length. For a 20-year marriage, it can be indefinite ^[6]. The duration math is set. The initial eligibility question stays fact-specific.

What factors matter as much as (or more than) marriage length?

Length is the headline factor. Judges look at a full picture, and most state statutes list the same core considerations even when the wording differs.

Income gap. The bigger the difference between what each spouse earns, the stronger the case for support, no matter how long the marriage lasted. A three-year marriage where one spouse gave up a high-paying career can still produce an award.

Standard of living during the marriage. Courts try to let both spouses hold onto something close to the lifestyle they shared. A long marriage at a high standard of living produces larger awards than a long marriage with modest finances.

Contributions to the marriage. This includes the non-financial kind: raising children, supporting a spouse's career, relocating for the other spouse's job. Courts hear testimony about these.

Age and health of each spouse. An older spouse who left the workforce during a long marriage faces a harder road back to self-sufficiency. Courts factor that in.

Education and employability. A spouse with a professional degree who has been out two years is in a very different spot than one who never finished high school and has been out thirty.

Fault, in some states. Roughly a third of states still let fault influence alimony. If adultery or abandonment is provable, it can shift the size or availability of an award. California is a no-fault state where the judge cannot consider marital misconduct when setting support ^[1].

For the wider view of spousal support, the overview on alimony covers award types and how courts structure them.

How does marriage length affect how long alimony lasts?

Even where there is no eligibility floor, length shapes duration almost everywhere. The general pattern goes like this.

Marriages under 5 years rarely produce long-term support. When an award happens at all, it is usually rehabilitative: short-term payments to let the lower-earning spouse get back on their feet. Think 12 to 24 months.

Marriages between 5 and 10 years sit in an uncertain middle. Courts vary widely here. You might see support lasting one-third to one-half the length of the marriage. You might see nothing, depending on the income facts.

Marriages over 10 years are where courts start taking support seriously. California's rule of thumb for sub-10-year marriages is support lasting half the marriage length. For marriages of 10 years or more, no fixed end date is presumed ^[1]. Florida's moderate-term and long-term categories kick in at 7 and 17 years ^[3].

Marriages of 20 years or more carry the strongest case for permanent or indefinite support, especially if one spouse left the workforce long-term. Illinois and several other states presume indefinite support for marriages over 20 years ^[6].

These are tendencies, not guarantees. A 25-year marriage where both spouses earned similar incomes throughout may produce little to no support. A 6-year marriage where one spouse sacrificed a medical career might produce several years of real payments.

What is the 10-year marriage rule people keep mentioning?

Two separate legal contexts feed this myth. They are worth untangling.

First, Social Security. If your marriage lasted at least 10 years, you can claim Social Security benefits on your ex-spouse's work record, provided you are at least 62, currently unmarried, and your own benefit would be lower than 50% of your ex's ^[7]. The Social Security Administration states it plainly: "Your marriage must have lasted at least 10 years" ^[7]. That rule is federal and it is real. It has nothing to do with state alimony law.

Second, Texas alimony. Texas Family Code Section 8.051 sets a 10-year floor for spousal maintenance eligibility in most cases ^[2]. Live in Texas, and if your marriage lasted 9 years and 11 months with no disability or violence involved, you almost certainly cannot get court-ordered spousal maintenance.

Outside Texas and the Social Security context, the 10-year number is not a law anywhere. Courts in most states will hear alimony arguments for marriages of any length, and the award rests on the full set of factors.

Can you get alimony from a short marriage (under 5 years)?

Yes, in most states. It is just uncommon and usually modest.

For a very short marriage, a court awarding support is thinking rehabilitative, not permanent. The logic runs: this spouse's earning ability took a hit during the marriage, or this spouse gave up something concrete for the other, and a year or two of payments helps them get back to independence.

What makes a short-marriage award more likely: a spouse who was pregnant during the marriage and cannot immediately return to work, a spouse who relocated for the other's job and lost seniority or clients, or a significant income gap that opened up during even a brief marriage.

Here is what to know. Most contested alimony cases that produce awards from short marriages involve some mix of income disparity and a concrete sacrifice. Length alone rarely drives an award under five years.

If you are doing your own uncontested divorce and you and your spouse have already agreed on support (or agreed there will be none), you put that agreement in your settlement paperwork. The court generally approves it as long as it is not unconscionable. A service like DivorceClear's $149 document packet can generate the settlement agreement forms for your state, which is where that agreement lives in the legal record.

Does a long marriage guarantee alimony?

No. Long marriages raise the probability and the likely duration of support, but a 30-year marriage between two high earners may produce no alimony at all.

The income and self-sufficiency question still controls. If both spouses can support themselves at something close to the marital standard of living after divorce, most courts decline to order ongoing support. Alimony is about need and ability to pay, not a reward for longevity.

A 20-year marriage where both spouses worked throughout, kept similar careers, and built roughly equal assets can end with no spousal support order. A 12-year marriage where one spouse left a career to raise children and has not worked in a decade will almost certainly produce an award.

Long marriages do shift the burden of the argument. In Massachusetts, the Alimony Reform Act of 2011 presumes that general term alimony for a marriage of 20 or more years may be indefinite ^[4]. A spouse arguing against support in that situation has to rebut the presumption.

How do courts calculate the amount of alimony, separate from length?

Marriage length tells a court whether and for how long to award support. The amount is a separate question, and the methods vary a lot by state.

Some states use a formula. Illinois uses one under 750 ILCS 5/504 that produces a guideline amount based on both spouses' incomes ^[6]. California has no statewide formula for spousal support in a divorce. The guideline formula applies to temporary support only, so judges hold wide discretion over final orders ^[1].

The most common informal benchmark is 25 to 35 percent of the difference in the spouses' gross incomes. That is not law anywhere. It is a pattern that shows up in negotiations and some judicial approaches. Nobody has great national data on average awards, because most family court records are not aggregated publicly.

Temporary support (also called pendente lite support) is almost always formula-driven and separate from the final order. It covers the stretch between separation and final divorce, and the amounts are usually not tied to marriage length at all.

What happens to alimony if the receiving spouse remarries or cohabits?

Remarriage of the recipient spouse ends alimony in almost every state, automatically. It is often written into the divorce order, but it would apply by statute even if it is not.

Cohabitation is messier. About half of states let the paying spouse petition to reduce or end support if the recipient moves in with a romantic partner, on the theory that the new partner's contributions reduce need. Florida's 2023 reforms made supportive relationships grounds to modify or terminate alimony ^[3]. California takes a softer path, treating cohabitation as a rebuttable presumption that need has dropped without ending support automatically.

The paying spouse's remarriage generally does not end alimony. That one cuts against most people's intuition, but it is correct. The obligation runs to the recipient based on that recipient's need, not on the payer's new household.

Death of either party ends alimony in almost every jurisdiction, though some states let support continue from the estate for a set period if the decree says so.

These rules matter when you negotiate. You can often agree to different cohabitation terms than your state's default if both parties consent. Put it in writing in your settlement agreement.

How is alimony different from property division and child support?

These three get conflated all the time. They should not.

Property division splits what you own together: the house, retirement accounts, debt. It is a one-time event at divorce, not ongoing. Marriage length affects property division in some states (longer marriages may give courts more flexibility), but the framework is separate from alimony.

Child support runs on a formula in every state, driven by each parent's income and parenting time. Marriage length is irrelevant to it. You can get child support from a one-year marriage. The child support calculator gives a rough number for your state.

Alimony is about one spouse's financial need and the other's ability to pay. It is ongoing and modifiable. Courts can change it if circumstances change materially, and it ends under the conditions above.

In an uncontested divorce, you and your spouse negotiate all three together, which usually beats handing the decision to a judge. Once you agree, those terms go into your divorce papers, which are filed with the court and become a binding order.

Uncertain about the mechanics? Speaking with a divorce attorney, even for a single consultation, can tell you whether a proposed alimony agreement is reasonable for your state.

What should you do if you think you're entitled to alimony but your spouse disagrees?

Start with your state's statute. Every state legislature has published its alimony factors online. Search for your state plus "spousal support statute," or check your state court's self-help center. Many state judiciary websites have plain-language guides. That is your starting point, not a friend or a forum.

Next, document everything tied to the factors. Your employment history, what you gave up, income tax returns for the last three to five years, your actual monthly budget, your spouse's income. The more concrete the picture of need and disparity, the stronger your position.

If you and your spouse cannot agree, alimony gets decided by a judge in a contested hearing. That means lawyers, depositions, financial disclosures, and real cost. Contested divorces in the U.S. typically run $15,000 to $30,000 per spouse in legal fees, and cases with disputed alimony run higher. That is the honest cost of letting a judge decide.

Negotiate an agreement, even an imperfect one, and you avoid that cost and get certainty. Mediation is an underused middle path: a neutral mediator helps you and your spouse reach a number you can both live with, for a fraction of litigation cost.

If you want legal strategy rather than just paperwork, working with a divorce lawyer makes sense for the negotiation phase even if you handle the filing yourself. The call about when to bring in professional help is real, and pretending it is never necessary would be dishonest.

How do you request alimony in your divorce paperwork?

In a contested divorce, alimony is requested in the initial petition and argued at hearing. In an uncontested divorce where you have already agreed on support, it goes into the marital settlement agreement, also called a separation agreement or property settlement agreement depending on your state.

The settlement agreement should spell out the amount per month, the duration (including what triggers termination), how and when payments are made, and what happens if the payer misses one. A vague line that just says "spouse will pay support" is not enforceable in any useful way.

Tax note: under the Tax Cuts and Jobs Act of 2017, alimony paid under divorce agreements executed after December 31, 2018 is no longer deductible by the payer and no longer counted as income by the recipient ^[8]. This reversed decades of prior tax treatment and matters a lot when you negotiate the number. A $2,000 per month payment means something different post-2018 than it did before.

If you are preparing documents yourself, DivorceClear's document packet includes state-specific settlement agreement templates with fields for spousal support terms. The packet covers the filing forms for uncontested cases where you have already reached agreement.

After your divorce is final, enforcing the order if your ex stops paying means going back to court. Most states allow wage garnishment and contempt proceedings for missed payments. That is a separate process from the divorce itself, handled through your state's family court.

Frequently asked questions

Is there a minimum number of years you have to be married to get alimony?

In most states, no. Courts treat marriage length as one factor among many rather than an eligibility cutoff. Texas is the main exception: its Family Code Section 8.051 requires at least 10 years of marriage for most spousal maintenance claims. Every other state will at least hear an alimony argument from a short marriage, though short marriages rarely produce awards.

Does the 10-year marriage rule apply to alimony everywhere?

No. The 10-year rule is real in two specific contexts: Texas state alimony law (Family Code 8.051) and federal Social Security benefits for divorced spouses (SSA rules). Outside Texas, no other state has codified a 10-year alimony floor. In most states, courts weigh length as one factor among many and can award support from marriages of any duration.

Can I get alimony after a 2-year marriage?

Legally, yes in most states, though it is uncommon. Courts in nearly every state will consider it if there is a meaningful income gap or a concrete sacrifice (career, relocation, pregnancy). Any award will almost certainly be short-term and rehabilitative rather than long-lasting. Texas is the exception, where a 2-year marriage almost certainly does not qualify.

How long does alimony last after a 10-year marriage?

It varies by state. California presumes no fixed end date for 10-plus year marriages but still requires proof of need. Illinois's formula produces support running about 40% of the marriage length (roughly 4 years for a 10-year marriage), potentially longer based on circumstances. Florida now treats marriages of 7 to 17 years as moderate-term with support generally capped at the marriage length.

Does a 20-year marriage automatically qualify for permanent alimony?

Not automatically, but it raises the probability significantly. Massachusetts's Alimony Reform Act creates a presumption that general term alimony may be indefinite after 20 years. Illinois allows indefinite support for 20-plus year marriages. Florida eliminated permanent alimony in 2023. In all cases, the court still looks at need and ability to pay, and two high earners may get no alimony award even after 20 years.

What if my spouse and I agree on alimony ourselves. Does the court still have to approve it?

Yes, but approval is usually a formality in uncontested cases. As long as your settlement agreement is in writing, signed by both parties, and not obviously unconscionable, most courts accept and incorporate it into the divorce decree. The judge is not going to second-guess a reasonable negotiated number. Put the agreed amount, duration, and termination conditions in the settlement agreement precisely.

Does cheating affect alimony?

It depends on the state. Roughly a third of states still allow fault, including adultery, to influence alimony awards. In those states, a cheating spouse might receive less or pay more than they otherwise would. California, Florida, and several other no-fault states prohibit courts from considering marital misconduct when calculating support amounts. Check your state's specific statute on fault and alimony.

How does marriage length affect alimony in California specifically?

California Family Code Section 4320 lists length as one of fourteen factors. For marriages under 10 years, courts typically presume support lasts half the marriage length. For marriages of 10 years or more, no fixed end date is presumed and the court retains ongoing jurisdiction over support unless the order says otherwise. Need and ability to pay still drive both eligibility and amount.

Is alimony taxable income after the 2017 tax law changes?

For divorce agreements finalized after December 31, 2018, alimony is no longer deductible by the payer and not counted as taxable income by the recipient. This changed under the Tax Cuts and Jobs Act of 2017. Agreements finalized before January 1, 2019 keep the old tax treatment (deductible to payer, taxable to recipient) unless the parties modify the agreement and opt into the new rules.

Can alimony be modified after divorce if my financial situation changes?

Yes, in most states. Either spouse can petition the court to modify alimony if there has been a substantial change in circumstances, such as a job loss, a major income increase, retirement, or the recipient's cohabitation with a new partner. The bar for modification is usually proving the change is material and not temporary. Some agreements waive the right to modification, which courts generally enforce.

Does remarriage end alimony payments?

The recipient's remarriage ends alimony in virtually every state, either automatically by statute or per the divorce order. The payer's remarriage generally does not end alimony. Cohabitation by the recipient without remarriage may reduce or end support in about half of states, particularly after Florida's 2023 reforms. Check your state's rules and write the conditions clearly into your settlement agreement.

What is the difference between alimony and spousal support?

They mean the same thing. Different states use different terms: alimony, spousal support, spousal maintenance, or partner support. The underlying legal concept is identical in all cases: ongoing financial payments from one former spouse to the other after divorce. The eligibility rules, amounts, and duration all depend on state law regardless of the term used.

How do I find out the alimony rules specific to my state?

Start with your state court's official self-help center, accessible through your state judiciary website. Most publish the statutory factors in plain language and some have worksheets. You can also look up your state's family code directly, searching for terms like spousal support, alimony, or spousal maintenance. For Texas, that is Family Code Chapter 8. For California, Family Code Section 4320.
