Florida's 2023 alimony law (s. 61.08)

Florida ended permanent alimony for new cases in 2023. A court can now award bridge-the-gap (up to 2 years), rehabilitative (up to 5 years, with a specific plan) or durational alimony. Durational alimony has hard limits:

Not after a marriage of under 3 years.
Amount: no more than the recipient's reasonable need or 35% of the difference between the parties' net incomes, whichever is less.
Length: no more than 50% of a short-term marriage (under 10 years), 60% of a moderate-term marriage (10 to 20 years) or 75% of a long-term marriage (20+ years), unless exceptional circumstances are proven by clear and convincing evidence.
Marriage length runs from the wedding to the date the divorce is filed. Alimony ends at either party's death or the recipient's remarriage.

Worked example

Net incomes of $10,000 and $4,000 a month differ by $6,000, so durational alimony can't exceed 35% × $6,000 = $2,100 a month (less if the recipient's need is lower). After a 15-year, moderate-term marriage it can last at most 60% × 15 = 9 years. Compare California and Illinois; this is an estimate, not legal advice.
