Alimony and spousal support are two words for the same thing: a legal agreement to provide financial support to a former spouse after a divorce.

It varies. The duration of spousal support depends on factors like the length of the marriage, the earning potential of each spouse, and the state you live in.

In most states, there isn't a minimum amount of time you need to be married in order to receive alimony or spousal support. But the length of time you were married can influence how long alimony and spousal support last.

Alimony and spousal support are official ways to redistribute wealth and resources to one spouse after a marriage ends. During many relationships, one spouse often ends up taking on responsibilities that impact their career and income—like childcare, homemaking, or other unpaid work. Since the higher paid spouse benefitted from this unpaid work, alimony or spousal support offers a way for the lower paid spouse to get back on their feet. In most cases, support is paid by the higher-earning spouse to the lower-earning one.

Alimony and spousal support are typically determined based on factors like the length of the marriage, the income and earning potential of each spouse, and the standard of living during the marriage.

In many states, spousal support ends when the receiving spouse remarries. Some states also allow adjustments if the receiving spouse is living with a new partner. The exact rules depend on your state and court order.

Yes. Filing for divorce does not affect eligibility. Courts focus on financial need and ability to pay, not who initiated the case.

For divorces finalized after December 31, 2018, alimony is generally not tax-deductible for the paying spouse and is not considered taxable income for the receiving spouse under federal law. Earlier agreements may follow different rules.

It generally comes down to need and ability to pay: courts look at whether one spouse has significantly less income or earning potential than the other, especially after a long-term marriage. It's less about checking a fixed list of boxes and more about showing a real gap between what each spouse earns or can earn — the specific factors used to size the payment are covered above.

Rules vary by state, but common factors that can reduce or eliminate alimony include a short marriage, both spouses having similar incomes and earning potential, or evidence of marital misconduct in states that still consider fault. A judge makes the final call based on the specifics of the case.
