No.  The only way your past debts can reach her money is if it's in an account (or property) that's in both of your names.  So, very simply, you don't have a joint bank account, if she buys a house, your name stays off it.

Originally, the law looked at a married couple as a single "person" and the husband controlled the money, usually, even if it had come from his wife or his wife's property.  That's ancient history now;  your creditors can't sue your wife, for pre-marital debts, since they have no contractual connection to her.
