The bank is auctioning our house. If I file for bankruptcy, can I keep the house?

In order to keep the house, you will have to file for bankruptcy before the auction date. If you file after the house is auctioned off then the house will no longer be yours and you will have no relevance to the person who bought the house at the auction. You should file for bankruptcy plenty of time before the auction in order to give your attorney time to file all necessary paperwork.
