Mississippi Alimony Laws: How Spousal Support Works (2026)

Frequently Asked Questions

Does Mississippi have a formula for calculating alimony?

No. Mississippi does not use a statutory formula or percentage for alimony. A chancery court judge evaluates the twelve Armstrong factors, including income, earning capacity, length of marriage, standard of living, and fault, and reaches a discretionary decision. No two cases are guaranteed to produce the same result.

How long does alimony last in Mississippi?

Duration depends on the type of alimony. Periodic alimony continues until the recipient remarries, either party dies, or a court modifies or terminates it. Rehabilitative alimony lasts for a fixed period set by the court. Lump-sum and reimbursement alimony end when the fixed obligation is fully paid.

Can a spouse lose alimony for living with a new partner?

Yes, under the de facto marriage standard. If the recipient cohabits with another person in a relationship that resembles marriage, sharing finances, living arrangements, and mutual support, the paying spouse can petition to terminate periodic alimony. Proof of cohabitation creates a legal presumption in favor of termination, and the burden shifts to the recipient to rebut it.

Does adultery affect alimony in Mississippi?

Yes. Fault, including adultery, is one of the twelve Armstrong factors. A court may reduce or deny alimony to a spouse who committed adultery. The innocent spouse in a fault-based divorce may receive a more substantial award. Fault does not automatically bar or guarantee alimony; it is weighed alongside all other factors.

Can alimony be changed after the divorce is final?

Periodic and rehabilitative alimony are modifiable. Either party can petition the court to increase, decrease, or terminate the award if a clear and substantial change in circumstances has occurred since the decree. Lump-sum and reimbursement alimony are generally non-modifiable once entered.

Is alimony taxable income in Mississippi?

For divorce agreements signed after December 31, 2018, alimony is not deductible by the payer and is not taxable income for the recipient under federal law (and Mississippi follows federal treatment). For agreements signed before January 1, 2019, the older rules apply: payers deduct and recipients include the payments as income.

Which court handles alimony in Mississippi?

Chancery courts have exclusive jurisdiction over divorce and alimony in Mississippi. Judges who sit in chancery are called chancellors. All alimony disputes, initial awards, modifications, and enforcement actions, are filed in the chancery court for the county where the parties reside.
