Is half everything still his if...?

First, shared property is usually evenly divided. This will include you business, vehicles, furniture, house... everything. Property given to your children is theirs and is not part of the divorce proceedings. You husband's bad habits won't necessarily enter into the divorce proceedings but they will figure heavily in the custody part of the divorce. The best advice I can give you is to hire a good family practice lawyer and be prepared for some rough times.
