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. Tennessee: Conservative educational estimate based on need, ability to pay, income disparity, economic disadvantage, marriage length, earning capacity, standard of living, rehabilitation prospects, and Tennessee 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. Tennessee: Tennessee has no fixed statutory duration formula. Rehabilitative alimony lasts for a period tied to education, training, or increased earning capacity. Transitional alimony lasts for a definite period needed to adjust to the economic consequences of divorce. Alimony in futuro is long-term periodic support and may be indefinite where rehabilitation is not feasible. Alimony in solido is a fixed total amount paid in installments or lump sum. Duration depends on the alimony type, need, ability to pay, rehabilitation prospects, and statutory factors.
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. Tennessee: Most ongoing alimony awards may be modified upon a substantial and material change in circumstances. Alimony in solido is generally non-modifiable because it functions similarly to a property settlement.
