Legal Question in Family Law in Florida

Usually, yes, it's too late. There are a couple of very small (VERY SMALL) exceptions that allow you to change your mind after you sign off on a settlement agreement in a divorce case, so you may want to talk to a lawyer to see if the exceptions apply to you. But the exceptions almost never happen. For instance, if someone held a gun to your head as you signed--literally held a real gun to your head--you'd have an exception. That's how tough it is to meet the exceptions.
