Key Differences

Calculation

Alabama: Alabama has no mandatory mathematical formula for alimony. Courts may award rehabilitative or periodic alimony only after finding that the requesting spouse lacks sufficient separate estate or resources to preserve, as much as possible, the economic status quo of the marriage; that the other spouse can pay without undue economic hardship; and that the circumstances make an award equitable. Rehabilitative alimony is preferred when feasible. South Dakota: Conservative educational estimate based on need, ability to pay, income disparity, marriage length, earning capacity, post-divorce financial condition, age, health, marital standard of living, property division, and South Dakota equitable factors; no mandatory statewide formula applies.

Duration

Alabama: Rehabilitative alimony is generally limited to 5 years absent extraordinary circumstances. Periodic alimony is generally limited to a period not exceeding the length of the marriage, unless the court finds deviation is equitably required. For marriages of 20 years or longer, there is no statutory time limit on eligibility for periodic alimony. If no alimony is awarded and jurisdiction is not reserved at the time of divorce, the court generally loses jurisdiction to later award rehabilitative or periodic alimony. South Dakota: South Dakota has no fixed statutory duration formula. Temporary alimony may be awarded while the divorce is pending. Post-divorce alimony may be rehabilitative, restitutional, permanent, or another equitable form depending on the facts. Rehabilitative support may be time-limited and tied to education, training, or self-support. Permanent or longer-term support may be possible where age, disability, health, or long-term dependency prevents self-support, but it is not automatic.

Modification

Alabama: Periodic alimony may generally be modified upon a material change in circumstances. Rehabilitative alimony may be modified before the end of its term when statutory standards are met, while alimony in gross is typically treated as a fixed property-like obligation. South Dakota: South Dakota alimony may be modified when a substantial change in circumstances justifies review, depending on the award type and decree terms. Courts evaluate changes affecting need, income, earning capacity, health, or ability to pay.

State Profiles

Alabama

Alabama alimony law emphasizes rehabilitative support first, with periodic alimony available only when rehabilitation is not feasible or is insufficient. Courts must make statutory findings before awarding rehabilitative or periodic alimony under Ala. Code § 30-2-57. The state does not use a mandatory mathematical formula for amount or duration.

Eligibility: A spouse may qualify only if the court finds that the spouse lacks a sufficient separate estate to preserve, as much as possible, the marital economic status quo, the other spouse can pay without undue economic hardship, and the circumstances make alimony equitable. Rehabilitative alimony is generally preferred and is commonly limited in duration. Periodic alimony is reserved for cases where rehabilitation is not feasible or fails to preserve the economic status quo.

South Dakota

South Dakota authorizes alimony when a divorce is granted and permits the court to require one spouse to make a suitable allowance for the other's support. The state does not use a mandatory statewide formula. Courts rely on discretionary factors such as marriage length, earning capacity, financial condition, age, health, social standing, and fault-related responsibility for the breakup.

Eligibility: A spouse may qualify if the court finds support suitable after reviewing the parties' financial and personal circumstances. South Dakota courts consider marriage length, earning ability, property division, age, health, social standing, and fault or responsibility for the divorce. Eligibility depends on equity rather than a strict income threshold.
