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. Missouri: Conservative educational estimate based on statutory eligibility, reasonable need, ability to pay, income disparity, marriage length, financial resources, earning capacity, standard of living, property division, and Missouri statutory 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. Missouri: Missouri has no fixed statutory duration formula. Maintenance may be ordered for a fixed term, modifiable ongoing term, nonmodifiable term if specified, or denied. Duration depends on reasonable need, ability to pay, time needed for education or training, marriage length, age, health, earning capacity, property division, and the court's equitable judgment. Maintenance may be modified only under the applicable statutory standard and may terminate under the order, death, remarriage, agreement, or further court order where applicable.
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. Missouri: Maintenance may be modified under Mo. Rev. Stat. § 452.370 upon changed circumstances so substantial and continuing that the existing terms are unreasonable. Parties may also create nonmodifiable maintenance through qualifying agreements, subject to Missouri law.
