Will I be affected if my ex files for bankruptcy?

The law provides that the Debt reporting agencies must keep separate files on Husbands and Wives. However sometimes it bleeds over into each others files where for example both parties are liable for the joint debt. In Tennessee you are liable for your wife's medical bills regardless of whether she files Bankruptcy or not. You should file Bankruptcy also. Hire a lawyer.

First, she is not your ex but your current wife. Separation does not make a spouse and "ex" even if legally separated. I will still refer to her as your "ex" nevertheless for convenience. The bankruptcy by your ex will not affect you. You might still be liable for her medical bills if the bills were incurred while you were married and living together. It is unlikely that any creditor will go after you but the liability is there. The filing of the bankruptcy by your ex will probably cause the creditors to write off the debts and never bother you either for those debts. I do not see how her filing for bankruptcy will affect you negatively. It might affect you positively by getting those creditors off your back and putting those debts to rest forever. Again, technically you might be liable for her medical bills during the time you were married and living together but it is highly unlikely you will be sued and her bankruptcy will make that even less likely.

Based on what you provided it does not sound like it.
