Currently there is a bill pending with the Florida Legislature to eliminate permanent alimony. One thing I have learned over the 40 years practicing law is that permanent alimony is not permanent. This type of alimony can be modified if there is a substantial change in circumstances unanticipated since the entry of the Final Judgment of Dissolution of Marriage.
This could be because the person paying alimony lost his or her job, or retired. Or it could be because the person receiving the alimony just got an inheritance. The best thing to do if circumstances change is talk to a qualified attorney about your options for reducing or eliminating your payment.
