If you commit adultery in Florida can you sue for alimony

Not if the other party (that didn't commit the adultery) has a really good lawyer. And pictures.

But let me correct that, you CAN sue for it... but that doesn't mean it would be awarded. I know of cases first hand that photos from a private eye, and lots of documentation got the husband off the hook completely for any Alimony payments (personal friend). The wife was who cheated in that case.

I may disagree, first if you can get alimony you are divorced and are free to sleep or live with who you want.
Normally this has no effect on alimony, just getting remarried.

Well, the case I mentioned is probibly an exception rather than the rule... but he was very wealthy, she cheated, got caught (I won't give the details so they can't be identified from it), but a divorce was granted in VA a community property state, and while he did have to pay child support for the kids he didn't keep custody of, he never had to pay a dime in alimony. And she wasn't wealthy at all, before the marriage and most definitely not since. The only thing she walked away with was 1/2 the value of the house.

I guess it all depends on having a really good lawyer and the right judge.

You need to be more careful when issuing advice on the law boards. Fr_Chuck is correct and follows Florida law. The situation you are relating to follows Virginia law and it is quite different. Va law allows for removal of spousal support on grounds of adultery ( §§ 20-91) but there is no such caveat in Florida family law.
