Mont. Code § 25-14-106
A party or witness examined in proceedings authorized by parts 1 and 2 of this chapter is not excused from answering a question on the ground that the party's or witness's examination will tend to convict the party or witness of the commission of a fraud or to prove that the party or witness has been a party or privy to or knowing of a conveyance, assignment, transfer, or other disposition of property for any purpose or that the party or witness or any other person claims to be entitled, as against the judgment creditor or a receiver appointed or to be appointed in the proceedings, to hold property derived from or through the judgment debtor or to be discharged from the payment of a debt that was due to the judgment debtor or to a person in the judgment debtor's behalf. However, an answer cannot be used as evidence against the person answering in a criminal action or criminal proceeding.
