Legal Question in Family Law in Florida

Simple answer is "no" unless you have some sort of written agreement giving him an interest. The courts disallowed "palamony" suits years ago. Alimony is only for people who were married and there is no common law marriage in Florida.

no

Since you aren't married, that would mean that he can't go after any of your 401(k), and he couldn't get alimony from you. Some states allow for palimony between unmarried couples, but Florida isn't one of them. Also, Florida doesn't have common law marriage, so if you didn't get a marriage license and have a wedding, you aren't married, and he can't take any of your property (nor can you get any of his) in divorce court, and no one gets alimony.

No.
