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. North Carolina: Conservative educational estimate based on dependent-spouse need, supporting-spouse ability to pay, income disparity, marriage length, marital standard of living, earning capacity, property division, and North Carolina 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. North Carolina: North Carolina has no fixed statutory duration formula. Postseparation support usually lasts until a specified date, final alimony order, dismissal, divorce judgment if no alimony claim is pending, or further court order. Final alimony may be for a definite or indefinite period and may be paid periodically, in a lump sum, by income withholding, transfer of title, possession of property, security interest, or another method ordered by the court. Alimony generally terminates on death of either party, remarriage or qualifying cohabitation of the recipient, or as otherwise ordered.
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. North Carolina: Alimony may be modified upon a showing of changed circumstances unless the parties entered a non-modifiable agreement. Courts examine whether the change materially affects need, ability to pay, or overall fairness.
