Mr. Gotzh is correct with one exception.
If your bank and your mortgage company are one in the same they can and will take money from your savings to go towards a debt. I suspect that since you are mortgaged through Countrywide and because i have never heard of a savings account with them this will not be the case though.
It depends on whether the Lender has served you or not personally. If they have they have the right to secure a deficiency judgment. Assuming your house is sold at the auction for 100k and you owed 200k, the Lender has the right to come after you for the 100k as a deficiency judgment. Please retain qualified counsel to go over these points with you as soon as possible.
