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 not child support—it is money paid to support the ex-spouse's living expenses, not children. The paying spouse sends the money to the receiving spouse on a schedule set by the divorce decree or separation agreement, usually monthly.
Alimony exists because divorce can leave one spouse in a worse financial position than the other. If one person stayed home to raise children or support the other's career, or if one spouse earned significantly more, the court may order the higher earner to pay the lower earner for a set period or indefinitely. The amount and duration depend on state law, the length of the marriage, each person's income and earning potential, and the standard of living during the marriage.
Alimony is different from child support (which goes toward children's care) and from a property settlement (which divides assets like a house or retirement account). You can owe alimony, child support, or both at the same time.
Key Takeaways
- Alimony is a monthly payment from one ex-spouse to another, ordered by a court as part of a divorce or separation agreement.
- The amount and length of alimony depend on state law, how long the marriage lasted, each person's income, and the couple's standard of living during the marriage.
- Alimony ends when the receiving spouse remarries, either spouse dies, or the court-ordered time period expires—unless the order says otherwise.
- If you stop paying alimony without a court order to change the amount, you can be held in contempt of court and face wage garnishment, liens, or jail time.
- Either spouse can ask the court to modify (change) the alimony order if income or circumstances change significantly.
How alimony is calculated and who pays
There is no single national formula for alimony. Each state has its own rules about how much one spouse must pay and for how long. Some states use a formula based on the difference between the spouses' incomes; others give judges broad discretion to decide based on the facts of the case.
Generally, the spouse with the higher income or earning potential pays alimony to the spouse with lower income. The court looks at each person's salary, job prospects, education, age, and health. If one spouse left the workforce to care for children or support the other's education or career, the court may assume that person has lower earning power and award alimony to help them rebuild.
The length of the marriage matters significantly. Short marriages (often defined as fewer than 5 to 10 years, depending on the state) may result in temporary alimony lasting only a few years. Long marriages often result in longer-term or indefinite alimony. A marriage of 20 years or more is more likely to trigger permanent alimony in states that allow it.
Types of alimony and how long they last
States recognize different categories of alimony, though the names and rules vary by location.
Temporary alimony is paid during the divorce process, before the final decree. It stops when the divorce is finalized and the court issues a final alimony order.
Rehabilitative alimony is meant to support a spouse while they retrain, finish education, or re-enter the workforce. It typically lasts a few years and ends on a date set by the court or when the receiving spouse reaches a certain income level.
Durational alimony lasts for a set number of years—often half the length of the marriage or longer. It does not continue indefinitely but provides support for a defined period.
Permanent alimony continues indefinitely unless the receiving spouse remarries, either spouse dies, or the court modifies the order. Permanent alimony is less common than it once was and is usually reserved for long marriages where one spouse has little earning potential.
Reimbursement alimony reimburses one spouse for expenses paid during the marriage—such as tuition for the other spouse's education—and typically ends after a set period.
When alimony ends or changes
Alimony stops automatically in most states when the receiving spouse remarries. Some orders also end alimony if the receiving spouse enters into a long-term cohabitation (living with a partner in a marriage-like relationship), though the rules on this vary by state.
Alimony also ends when either spouse dies. If the paying spouse dies, the receiving spouse generally has no claim against the estate unless the divorce decree specifically required the paying spouse to maintain life insurance or leave money in a will.
If the court-ordered time period expires (for example, "alimony ends on January 1, 2030"), the obligation ends on that date unless the receiving spouse asks the court to extend it before the deadline.
Either spouse can ask the court to modify the alimony order if circumstances change significantly—such as a job loss, serious illness, substantial raise, or retirement. The paying spouse must show a material change in circumstances to reduce or end alimony. The receiving spouse can ask for an increase if the paying spouse's income rises substantially. The court will not modify an order based on small or temporary changes in income.
How alimony payments are made and enforced
Alimony is usually paid monthly, though the divorce decree may specify a different schedule. Many states require the paying spouse to pay through the state's child support enforcement agency (even if there is no child support order), which tracks the payment and forwards it to the receiving spouse. This creates an official record of all payments.
Some couples arrange direct payment between themselves, but this is riskier for the receiving spouse because there is no official record. If a dispute arises later, the paying spouse might claim they paid when they did not.
If the paying spouse falls behind on alimony, the receiving spouse can ask the court to enforce the order. The court can order wage garnishment (the employer deducts alimony from the paycheck), place a lien on property (a claim against the house or car), intercept tax refunds, suspend the paying spouse's driver's license or professional license, or hold the paying spouse in contempt of court. Contempt can result in jail time until the back payments are made.
The receiving spouse can also hire a private collection agency or attorney to pursue the debt, though this costs money upfront.
Tax treatment of alimony payments
The tax treatment of alimony changed significantly for divorces finalized after December 31, 2018. For older divorces, alimony was deductible by the paying spouse and taxable income for the receiving spouse. For divorces finalized in 2019 and later, alimony is not deductible for the paying spouse and is not taxable income for the receiving spouse.
If your divorce was finalized before 2019, the old rules apply to you. If it was finalized in 2019 or later, the new rules apply. This is an important distinction because it affects how much money actually changes hands and how each person's taxes are filed.
Both spouses should consult a tax professional or accountant to understand how alimony affects their specific tax situation, especially if the divorce was finalized near the cutoff date or if the order was modified after 2018.
What happens if you cannot pay alimony
If you are ordered to pay alimony and your financial situation changes—you lose your job, become seriously ill, or your income drops—you should ask the court to modify the order rather than simply stop paying. Stopping payment without a court order is a violation and can result in serious consequences.
If you file a motion to modify and the court agrees that circumstances have changed, the judge can reduce the amount, suspend payments temporarily, or end the obligation. The court will not retroactively forgive back payments you owe, but it can prevent future payments from being as large.
If you ignore the order and do not pay, the receiving spouse can pursue enforcement. This can include wage garnishment, property liens, license suspension, and contempt charges. Contempt of court can result in jail time, and you remain liable for all back payments plus interest and court costs.
Frequently Asked Questions
Is alimony the same as child support?
No. Alimony is paid to support an ex-spouse; child support is paid to support children. You can owe both at the same time. Child support typically ends when the child reaches age 18 or finishes high school, while alimony may continue longer or indefinitely depending on the order and state law.
Can alimony be modified after the divorce is final?
Yes. Either spouse can ask the court to change the alimony amount or duration if there is a significant change in circumstances—such as job loss, illness, retirement, or a substantial increase in income. The court will not modify an order based on minor or temporary changes.
What happens to alimony if I remarry?
In most states, alimony ends automatically when the receiving spouse remarries. Some states also end alimony if the receiving spouse enters into a long-term cohabitation. The paying spouse does not need to ask the court to stop payments—they typically end by operation of law, though it is wise to notify the court in writing.
Can alimony be enforced if the paying spouse moves to another state?
Yes. The Uniform Interstate Family Support Act (UIFSA) allows states to enforce alimony orders across state lines. The receiving spouse can ask their state's child support enforcement agency to pursue collection in the other state, or can file in the other state's court. Moving does not eliminate the obligation.
What if the paying spouse retires?
Retirement may be grounds to modify alimony, but the court will not automatically end the obligation. The paying spouse must file a motion to modify and show that retirement significantly reduced their income. The court will consider the paying spouse's age, health, the length of the marriage, and whether the receiving spouse has other means of support.
