A Wyoming Subpoena to Testify at a Deposition in a Bankruptcy Case (or Adversary Proceeding) is a legal document issued by a court or an attorney to compel a witness to appear and give testimony in a bankruptcy case or adversary proceeding. It requires the witness to appear at a designated location, provide testimony under oath, and answer questions related to the case. There are two types of Wyoming Subpoena to Testify at a Deposition in a Bankruptcy Case (or Adversary Proceeding): a Subpoena Ducks Cecum and a Subpoena Ad Testificandum. A Subpoena Ducks Cecum requires the witness to bring documents or records related to the case. A Subpoena Ad Testificandum requires the witness to appear and testify, but does not require the witness to bring any documents or records.
