If you do not know where the judgment debtor has a savings or checking account, what personal property the debtor owns, or where the debtor works, you may obtain an information subpoena from the Office of the Special Civil Part Clerk. An information subpoena is a court paper containing questions about the debtor's assets.
You may serve an original and one copy of an information subpoena upon the debtor either personally or by registered and certified mail, return receipt requested, and simultaneously by regular mail. You also must provide a postage paid, addressed envelope with the information subpoena. The debtor must answer and return the information subpoena within 14 days from the date on which it was served. An information subpoena cannot be served more than once in a six month period without approval of the court. If the debtor does not answer the information subpoena, he or she is subject to contempt sanctions enforceable by the court.
