What Alimony Is and How It Works

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

Alimony (also called spousal support or maintenance) is a court-ordered payment from one former spouse to another. It is separate from child support and property division. The paying spouse sends money to the receiving spouse, usually monthly, for a set period or until a condition changes — like the receiving spouse remarrying or reaching retirement age.

Alimony exists because divorce can leave one spouse in a worse financial position than the other. A spouse who stayed home to raise children, worked part-time, or sacrificed career advancement during the marriage may have lower earning power after divorce. Alimony is meant to help that spouse become self-supporting or to recognize the financial sacrifices made during the marriage.

The amount, duration, and whether alimony is awarded at all depend on state law and the specific circumstances of the marriage and divorce. No two cases are identical, and judges have significant discretion in these decisions.

Key Takeaways

• Alimony is a payment from one former spouse to another, ordered by a court, and is separate from child support and property division.
• The paying spouse's income, the receiving spouse's income and earning capacity, the length of the marriage, and the standard of living during the marriage all affect whether alimony is awarded.
• Alimony can be temporary (lasting a few years), long-term (lasting many years or indefinitely), or awarded as a single lump sum.
• Alimony ends when the receiving spouse remarries, cohabits with a partner in most states, reaches a certain age, or when the paying spouse dies or becomes unable to work.

The difference between alimony, child support, and property division

These three are often confused because they all happen during divorce, but they serve different purposes. Property division splits marital assets — the house, retirement accounts, vehicles, and other property accumulated during the marriage. This is a one-time transfer. Child support is money paid for the care and upbringing of children and typically continues until the child turns 18 or finishes high school. Alimony is support for an adult spouse and has nothing to do with children or property.

A person can receive child support without receiving alimony, or alimony without child support, or both. They are calculated separately and ordered separately by the court.

What factors courts consider when deciding alimony

State law sets out the factors a judge must weigh. While these vary by state, most courts look at the same core information. The paying spouse's income and ability to pay is the starting point — a judge will not order alimony if the paying spouse cannot afford it. The receiving spouse's income and earning capacity matter equally; if the receiving spouse earns enough to be self-supporting, alimony may not be awarded or may be lower.

The length of the marriage affects the duration and amount. A 30-year marriage typically results in longer alimony than a 5-year marriage. Courts also consider the standard of living during the marriage — if a couple lived a high-income lifestyle, the receiving spouse may receive more alimony to maintain a similar standard. The age and health of both spouses, whether one spouse sacrificed education or career for the family, and the custody arrangement (if children are involved) all factor in.

Some states also consider fault — whether one spouse committed adultery or abuse — though many states have moved away from this. A few states require judges to consider whether the receiving spouse can retrain or return to work, and how long that would take.

Types of alimony and how long they last

Temporary alimony (called pendente lite in some states) is paid during the divorce process, before the final judgment. It stops when the divorce is final and is replaced by a permanent or long-term order, or it stops entirely if the judge decides no ongoing alimony is warranted.

Durational alimony lasts for a set number of years — often half the length of the marriage or some other period the judge sets. For example, a 20-year marriage might result in alimony lasting 10 years. Once that time ends, payments stop automatically unless the order is modified.

Long-term or indefinite alimony continues until a triggering event occurs: the receiving spouse remarries, cohabits with a partner (in most states), reaches retirement age, or one spouse dies. This is more common in long marriages or when the receiving spouse has a significant disability or health issue that prevents self-support.

Lump-sum alimony is a single payment instead of monthly payments. This is less common but can happen when one spouse has a large asset (like an inheritance or business sale) and the judge decides a one-time payment is appropriate.

How alimony is calculated

Many states use a formula or guideline to calculate alimony, similar to how child support is calculated. The formula typically takes the difference between the two spouses' incomes and applies a percentage — often 20 to 30 percent of that difference — over the duration set by the judge. For example, if one spouse earns $100,000 and the other earns $40,000, the difference is $60,000. At 25 percent, that would be $15,000 per year, or $1,250 per month.

However, formulas are not binding in all cases. Judges can deviate from the formula if the circumstances warrant it — if one spouse has significant assets, if the marriage was very long, or if the receiving spouse has a serious health condition. Some states do not use formulas at all and leave the calculation entirely to the judge's discretion based on the factors listed above.

The income used in the calculation includes wages, salary, bonuses, self-employment income, rental income, and sometimes investment income. It may also include income the judge believes a spouse could earn if they were working — for example, if a spouse is deliberately underemployed, the judge may "impute" higher income to that spouse.

When alimony ends or can be changed

Alimony ends automatically when the receiving spouse remarries. In most states, it also ends if the receiving spouse cohabits with a romantic partner for a set period (often 6 months to a year, depending on state law). Some states require the paying spouse to prove cohabitation; others allow the receiving spouse to report it.

Alimony ends when the paying spouse dies. The receiving spouse's right to future payments stops, though some states allow the receiving spouse to make a claim against the paying spouse's estate for arrears (unpaid alimony). Alimony also ends when the receiving spouse reaches a certain age, usually tied to the paying spouse's retirement age — often 65 or 67.

Either spouse can ask the court to modify the alimony order if circumstances change significantly. A substantial drop in the paying spouse's income, a serious illness, job loss, or a major change in the receiving spouse's circumstances (like a significant increase in income or a new job) can be grounds for modification. The paying spouse must show the change was not voluntary or anticipated when the order was made.

Alimony and taxes

As of 2019, alimony is no longer deductible by the paying spouse on federal income taxes, and the receiving spouse does not report it as income. This changed from the previous rule, where the paying spouse could deduct alimony and the receiving spouse had to report it as income. Divorce agreements finalized before January 1, 2019 may still follow the old tax rules, depending on state law and whether the agreement was modified.

State tax treatment varies. Some states follow the federal rule; others have different rules. The paying and receiving spouses should confirm the tax treatment with a tax professional or their state's tax authority, especially if the divorce was finalized before 2019 or if the order has been modified.

Frequently Asked Questions

Can alimony be awarded in a short marriage?

Yes, but it is less common. Courts consider the length of the marriage as one factor, but not the only one. A short marriage where one spouse sacrificed significantly — such as putting the other through professional school — can still result in alimony. The duration would typically be shorter than in a long marriage.

What happens if the paying spouse loses their job?

Job loss can be grounds to modify alimony, but the paying spouse must ask the court to change the order. straightforward stopping payments is not legal. The court will look at whether the job loss was voluntary (which may not reduce alimony) or involuntary (which may). The paying spouse's efforts to find new work also matter.

Can alimony be awarded if both spouses earn similar incomes?

It is possible but less common. If both spouses are self-supporting, a judge may decide alimony is not necessary. However, if one spouse earns significantly more, or if one spouse sacrificed career advancement during the marriage, alimony can still be awarded even if both are employed.

Is alimony the same in every state?

No. Each state has its own laws about when alimony is awarded, how it is calculated, and how long it lasts. Some states use formulas; others rely on judicial discretion. Some states consider fault; others do not. The rules in your state depend on your state's statutes and case law.

Can alimony be modified after the divorce is final?

Yes, either spouse can ask the court to modify alimony if there has been a substantial and unanticipated change in circumstances — such as a significant change in income, health, or employment status. The court will review the request and decide whether to change the amount or duration.
