A Wisconsin Subpoena to Testify at a Deposition in a Bankruptcy Case (or Adversary Proceeding) is a legal document issued by the court or a party in a bankruptcy proceeding that requires a witness to appear in court and provide testimony. The witness must answer questions and provide documents or other evidence related to the bankruptcy case. There are two types of Wisconsin Subpoena to Testify at a Deposition in a Bankruptcy Case (or Adversary Proceeding): 1. The party-issued subpoena: This type of subpoena is issued by a party in the bankruptcy case and requires the witness to appear and testify at a deposition or other proceeding. 2. The court-issued subpoena: This type of subpoena is issued by the court and requires the witness to appear and testify at a hearing or trial. Both types of subpoenas require the witness to provide sworn testimony, answer questions, and provide documents or other evidence related to the bankruptcy case. Failure to comply with the subpoena can result in serious consequences, including fines and/or imprisonment.
