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. Colorado: Colorado uses statutory advisory maintenance guidelines when maintenance is requested, the marriage lasted at least 3 years, and combined annual adjusted gross income is $240,000 or less. The guidelines do not create a presumption that maintenance will be ordered. Courts retain discretion and must consider need, ability to pay, income, property division, financial resources, marriage length, employability, health, and other statutory factors.
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. Colorado: For marriages under 3 years, the advisory duration table does not apply, though maintenance may still be considered in unusual circumstances. For marriages of 3 to 20 years, Colorado uses an advisory duration table beginning at about 31% of the marriage length for a 3-year marriage and increasing gradually to 50% of the marriage length by 12.5 years. For marriages over 20 years, the court may award maintenance for a fixed term or indefinitely, but generally should not order less than the 20-year guideline term without specific findings.
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. Colorado: Maintenance may be modified upon a substantial and continuing change in circumstances unless the parties validly agreed that maintenance would be non-modifiable. Courts evaluate financial developments affecting need or ability to pay.
