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. 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
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. 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
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. 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.
