Key facts: The $50,000 estate value threshold determines eligibility for Montana's small estate probate procedures; a mandatory 30-day waiting period applies under the Montana Statutory Probate Rules Code before estate property can be legally transferred or leased; proper legal authority must be obtained through either a Small Estate Affidavit or Letters Testamentary before executing any rental agreements; and all rental activities must comply with Montana landlord-tenant statutes once probate authority is established.
