No. You don't get his Dad's money by marrying him. If you stay married and he chooses to spend the money to have fun or increase his lifestyle, then you can have the fun of the increased lifestyle becasue your husband is living it, but you don't get to keep it when you leave him. It was his Dad's money, not yours. It was not earned by your husband, but his dad was nice enough to want him to have the advantage of it when he (the dad) was finished needing it. Nice for your husband. And nice for anyone who is currently living with him, kids or girlfriends or wives... But his Dad's estate has no meaning for his ex (or the woman who is divorcing him).
