Michigan Compiled Laws, Chapter 600. Revised Judicature Act of 1961 § 600.6110

Sec. 6110. (1) Upon an affidavit, showing to the satisfaction of the judge that any person has money or property of the judgment debtor, or is indebted to him, the judge may issue a subpoena requiring the judgment debtor or the person or both to appear at a specified time and place, and be examined on oath, and to produce for examination any books, papers, or records in his or its possession or control which have or may contain information concerning the property or income of the debtor.

(2) A corporation shall attend by and answer under the oath of an officer thereof, and the judge may, in his discretion, specify the officer. Either party may be examined as a witness in his own behalf, and may produce and examine other witnesses as upon the trial of an action. The judge may adjourn any proceedings under this chapter from time to time as he thinks proper.

(3) A party or witness examined under these provisions may not be excused from answering a question on the ground that his answer will tend to show him guilty of the commission of a fraud, or prove that he has been a party or privy to, or knowing of a conveyance, assignment, transfer, or other disposition of property for any purpose, or that he or another person claims to have title as against the judgment debtor or to hold property derived from or through the judgment debtor, or to be discharged from the payment of a debt which was due to the judgment debtor or to a person in his behalf. But an answer cannot be used as evidence against the person so answering in any criminal proceeding or action, except for perjury in making the answer.
