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. Massachusetts: Massachusetts has statutory alimony categories and statutory limits for general term alimony. The amount of alimony generally should not exceed the recipient's need or 30% to 35% of the difference between the parties' gross incomes. Courts still consider statutory factors and may deviate where appropriate.
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. Massachusetts: For general term alimony, Massachusetts uses statutory duration limits based on marriage length. For marriages of 5 years or less, alimony generally may not exceed 50% of the number of months of the marriage. For marriages over 5 and up to 10 years, the limit is generally 60%. For marriages over 10 and up to 15 years, the limit is generally 70%. For marriages over 15 and up to 20 years, the limit is generally 80%. For marriages over 20 years, alimony may continue indefinitely, subject to statutory termination, modification, retirement, and other rules.
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. Massachusetts: Most alimony awards may be modified upon a material change in circumstances unless the parties validly agree otherwise. Retirement, significant income changes, or other substantial developments may justify modification under the statute.
