Legal Question in Family Law in Florida

That's too big a question for an online forum like this, but I can give you some general rules:

If you owned property before you got married, you generally get to keep it. With houses, it can be a little different, since you may have used marital funds to pay off part of it. She may get some small part of the house, but how much depends on which jurisdiction in Florida you file.

All assets and debts that occurred after the day you got married get split evenly, regardless of whose name they are in, who bought them, who charged them, who earned what money, etc.

There may be alimony, but it usually depends on how long you've been married (at least ten or twelve years in a Tampa Bay area divorce, fifteen to twenty elsewhere). Other things, like disability or need to complete an education can cause alimony in a shorter marriage.

If there are kids, there will almost certainly be child support, even if custody is 50/50.
