No, they can't, unless your name is added to her deed by that time.  The bank could go after your joint checking or savings accounts, or similar assets, but that's because your name is on them.  They would be able to garnish your pay, but not hers.

For most purposes, marrying someone does not make you a party to your spouse's contracts, or debts, and it doesn't make you part owner of their assets that were theirs before the marriage and are still held in their own name alone.
