Depending on what type of bankruptcy you file, your co-signers either will or will not be protected by the automatic stay that goes into effect when your case is filed. In a chapter 13 case, there is co-debtor stay which is pretty much the same as a co-signer stay. That prevents creditors from going after the co-signer. That protection does not extend to chapter 7 filings. That's a consideration to bring up when you're planning your bankruptcy filing. It's something you should discuss with your attorney.
