What Alimony Means and How It Works

Alimony is money one spouse pays to the other after divorce or separation

Alimony is a court-ordered payment from one former spouse to another. It is not the same as child support — it is based on the income and needs of the two adults, not on children. The person who pays is called the payor; the person who receives it is called the recipient or payee.

Alimony exists because divorce can leave one spouse in a much weaker financial position than the other. If one person stayed home to raise children or support the other's career, or if one person earns significantly more, a court may order the higher earner to pay part of their income to the lower earner for a set period or indefinitely. The goal is to reduce the gap between their living standards after the marriage ends.

Not every divorce involves alimony. Courts look at factors like how long the marriage lasted, each person's income and earning ability, their age and health, and whether one person sacrificed career growth during the marriage. A short marriage between two working adults with similar incomes is unlikely to result in alimony. A 20-year marriage where one spouse left the workforce is more likely to.

Key Takeaways

• Alimony is a payment from one former spouse to another based on income difference and need, separate from child support.
• Courts decide whether alimony is owed by looking at marriage length, each person's income, age, health, and whether one spouse gave up career opportunities.
• Alimony can be temporary (lasting a set number of years) or permanent (lasting until the recipient remarries or either person dies).
• The amount and duration vary widely by state and by the specific circumstances of each marriage.
• Alimony payments are tax-deductible for the payor and taxable income for the recipient under current federal law, though this changed in 2019 for divorces finalized after December 31, 2018.

The difference between temporary and permanent alimony

Temporary alimony lasts for a set number of years — often half the length of the marriage, though this varies by state and judge. It is meant to give the lower-earning spouse time to finish education, build work experience, or transition to self-sufficiency. Once the time period ends, payments stop unless the recipient goes back to court and shows a change in circumstances that warrants extension.

Permanent alimony continues indefinitely, but "permanent" does not mean forever in practice. It ends if the recipient remarries, if either person dies, or if the payor retires and can no longer afford the payments (though courts are skeptical of retirement as a reason to stop). Permanent alimony is less common now than it was 20 years ago, and some states have moved away from it entirely.

A few states also recognize reimbursement alimony, which pays back one spouse for supporting the other through school or training. For example, if one spouse worked full-time to put the other through medical school, the court might order the doctor to reimburse the working spouse for those years of support.

How courts calculate the amount

There is no single national formula for alimony. Each state has its own rules, and many states use different methods depending on whether the alimony is temporary or permanent.

Some states use a percentage-of-income model: the payor pays a set percentage of their gross income (often 20 to 30 percent) to the recipient, adjusted for how many years the marriage lasted. Other states use a needs-based model: the court looks at what the recipient actually needs to live and what the payor can afford, then sets a payment that bridges the gap. A few states use a standard of living model: the court tries to keep both spouses at roughly the same standard they had during the marriage, which usually means higher payments.

Courts also consider whether the recipient can work. If someone is young, healthy, and trained for a career, the court may assume they will earn income and reduce or deny alimony. If someone is older, disabled, or left the workforce decades ago, the court may order higher payments or make them permanent.

When alimony ends or changes

Alimony stops automatically in most states if the recipient remarries. Some states also stop it if the recipient enters into a long-term cohabitation with a new partner, though the definition of "cohabitation" varies. Death of either spouse always ends alimony.

If circumstances change significantly after the divorce — the payor loses their job, the recipient gets a major promotion, or either person's health changes — either person can ask the court to modify the alimony order. The court will not change it just because someone is unhappy with the amount. The change has to be substantial and involuntary, like a job loss, or it has to reflect a major life event, like retirement.

Some divorce agreements include a clause that says alimony cannot be modified, which is binding in most states. Others allow modification only for temporary alimony, not permanent. Read the divorce decree carefully to know whether you can ask for a change.

Alimony and taxes

The tax treatment of alimony changed on January 1, 2019. For divorces finalized before that date, alimony payments are tax-deductible for the payor and taxable income for the recipient. For divorces finalized on or after January 1, 2019, alimony is not deductible for the payor and not taxable for the recipient.

This matters because it affects how much money actually changes hands. If you are paying alimony and can deduct it, your tax bill goes down, which reduces the real cost of the payment. If you are receiving alimony and it is taxable, you owe income tax on it, which reduces what you keep. After 2019, neither of those things happens — the payor gets no deduction and the recipient pays no tax.

If you are unsure which rule applies to your situation, check your divorce decree for the date it was finalized. If you are negotiating a new divorce settlement, talk to a tax professional or family law attorney about how the timing affects the real value of the payment.

Alimony versus spousal support and maintenance

The words alimony, spousal support, and maintenance mean the same thing — one former spouse paying the other. Different states use different terms. Some states call it "alimony," some call it "spousal support," and some call it "maintenance" or "spousal maintenance." A few states use more than one term depending on whether the alimony is temporary or permanent.

When you read your divorce papers or look up your state's laws, search for all three terms to make sure you are not missing information. A court order that says "maintenance" is just as binding as one that says "alimony."

Frequently Asked Questions

Can alimony be waived in a divorce agreement?

Yes. Both spouses can agree in writing that neither will pay alimony, and a court will usually honor that agreement. However, if one spouse signs away alimony under pressure or without understanding what they are doing, a court may set the waiver aside later. If you are considering waiving alimony, talk to a family law attorney first.

What happens if someone stops paying alimony?

The recipient can file a motion for contempt of court, which can result in fines, wage garnishment, or jail time for the payor. The court can also order the payor to pay the recipient's attorney fees. If the payor claims they cannot afford the payments, they can ask the court to modify the order, but they cannot straightforward stop paying on their own.

Does alimony count as income for other benefits?

Yes. Alimony is counted as income for purposes of means-tested programs like Medicaid, SNAP, and housing information. If you receive alimony and are on a government benefit program, report it to the program administrator, as it may affect your benefit amount or your continued may be able to access.

Can I get alimony if my spouse hid assets during the divorce?

If you discover after the divorce that your spouse hid income or assets, you can ask the court to modify the alimony order based on the newly discovered information. You will need proof — bank statements, tax returns, or other documents showing the hidden assets. Talk to a family law attorney about whether you have grounds to reopen the case.

Is alimony the same as a property settlement?

No. A property settlement divides the assets and debts accumulated during the marriage — the house, retirement accounts, cars, and so on. Alimony is an ongoing payment based on income and need. You can have one without the other, or both. They are separate parts of a divorce agreement.
