My husband/wife filed for bankruptcy. Can I get some information about his/her case?

The Trustee will give out certain information about cases to interested parties in the case. Note, however, that if you are not on the petition as a co-debtor in the case, the Trustee can only give you some general information that would be available to creditors or other interested parties. Since you are not the debtor in the case, you cannot make decisions about the case, and there is some information that you will not be provided. You cannot "handle" the case for the debtor.
