Whether you file for Chapter 7 or Chapter 13, you will be required to attend a Meeting of Creditors pursuant to 11 U.S.C. § 341. It’s not a court hearing but it does take place at the Federal Courthouse. Also, it will not be in front of a Judge but rather in front of a Trustee.
For a Chapter 7 filing, generally speaking, that is the only hearing you and your attorney will need to appear at. In a Chapter 13, however, your attorney will likely need to attend actual court hearings in front of the Judge. In most cases, your attorney can attend those court hearings on your behalf and you will not need to be present at them.
