Your ex filed for bankruptcy What will that do to you?

It will leave you responsible for any joint debts you had with your ex. That includes any arrears prior to the ex filing, attorney's fees, penalties, etc. That will in turn affect your credit score and your credit report.

If there are no joint debts, it should have little effect, but you may want to read her schedules in the bankruptcy court and get a new copy of your credit reports from the big three (Experian, TransUnion, Equifax), one free each year from www.annualcreditreports.com.
