Definition
Court-ordered or agreed payments from one former spouse to the other after a divorce or separation, also called spousal support or maintenance. The amount and duration depend on state law and the couple's finances. Under federal rules, alimony from agreements signed after 2018 is neither deductible for the payer nor taxable income for the recipient; older agreements may follow the opposite treatment.
Why it matters
Alimony is a fixed line in two budgets for years: the payer must fund it before discretionary spending, and the recipient has to plan for the date it ends. Lenders count it as a debt for the payer and, if it will continue long enough, as income for the recipient.
