Calculation
Florida: Florida no longer awards permanent alimony for initial petitions governed by the current statute. Courts may award temporary, bridge-the-gap, rehabilitative, or durational alimony only after making specific factual findings that the requesting spouse has actual need and the other spouse has ability to pay. Durational alimony is capped at reasonable need or 35% of the parties' net-income difference, whichever is less. Iowa: Conservative educational estimate based on need, ability to pay, income disparity, marriage length, marital standard of living, earning capacity, education, health, property division, and Iowa statutory factors; no mandatory statewide formula applies.
Duration
Florida: Florida classifies marriages as short-term if less than 10 years, moderate-term if 10 to less than 20 years, and long-term if 20 years or more. Bridge-the-gap alimony may not exceed 2 years. Rehabilitative alimony may not exceed 5 years and requires a specific rehabilitative plan. Durational alimony may not be awarded after a marriage lasting less than 3 years. Durational alimony may not exceed 50% of a short-term marriage, 60% of a moderate-term marriage, or 75% of a long-term marriage, except under exceptional circumstances proven by clear and convincing evidence. Iowa: Iowa has no fixed statutory duration formula. Support may be ordered for a limited or indefinite time. Rehabilitative support is usually time-limited and tied to education, training, or transition to self-support. Traditional support may be longer or indefinite in appropriate long-marriage cases involving age, health, dependency, or limited earning capacity. Reimbursement support is usually tied to a specific economic contribution or sacrifice. Duration depends on statutory factors and equitable circumstances.
Modification
Florida: Most alimony awards may be modified upon a substantial, material, and unanticipated change in circumstances. The party requesting modification must demonstrate that the statutory standard has been satisfied. Iowa: Iowa spousal support may be modified under Iowa Code § 598.21C when there is a substantial change in circumstances. Some support obligations may be affected by the decree terms or the nature of the award.
