TALLAHASSEE — Gov. Ron DeSantis on Friday signed a measure that will overhaul the state’s alimony laws, after three vetoes of similar bills and a decade of emotional clashes over the issue. The measure (SB 1416) includes doing away with what is known as permanent alimony. DeSantis’ approval came a year after he nixed a similar bill that sought to eliminate permanent alimony and set up a formula for alimony amounts based on the length of marriage. The approval drew an outcry from members of the “First Wives Advocacy Group,” a coalition of mostly older women who receive permanent alimony and who assert that their lives will be upended without the payments. “On behalf of the thousands of women who our group represents, we are very disappointed in the governor’s decision to sign the alimony-reform bill.
