The bill, which will take effect Saturday, also will set a five-year limit on what is known as rehabilitative alimony. Under the plan, people married for less than three years will not be eligible for alimony payments, and those who have been married 20 years or longer will be eligible to receive payments for up to 75 percent of the term of the marriage.

The new law will also allow alimony payers to seek modifications if “a supportive relationship exists or has existed” involving their ex-spouses in the previous year. Critics argued the provision is vague and could apply to temporary roommates who help alimony recipients cover living expenses for short periods of time.

Senate bill sponsor Joe Gruters, R-Sarasota, tried to assure lawmakers that the 2023 version would not unconstitutionally affect existing alimony settlements. This year’s proposal “went to what is currently case law,” Gruters told a Senate committee in April, pointing to the court ruling.

“So what you can do right now, under case law, we now codify all those laws and make that the rule of law. So we basically just solidify that. So from a retroactivity standpoint, no, because if anything could be modifiable before, it’s still modifiable. If it’s a non-modifiable agreement, you still can’t modify that agreement,” he said.
