Mont. Code Ann. § 72-3-1014

After the personal representative's appointment has terminated, the personal representative, the personal representative's sureties, or any successor of either, upon the filing of a verified application showing so far as is known by the applicant that an action concerning the estate is not pending in any court, is entitled to receive a certificate from the clerk that the personal representative appears to have fully administered the estate in question. The certificate evidences discharge of any lien on any property given to secure the obligation of the personal representative in lieu of bond or any surety but does not preclude action against the personal representative or the surety.
