Mont. Code Ann. § 18-1-118

Money may not be spent by a state agency under a contract with a nonstate entity unless the contract contains a provision that allows the legislative auditor sufficient access to the records of the nonstate entity to determine whether the parties have complied with the terms of the contract. The access to records is necessary to carry out the functions provided for in Title 5, chapter 13. A state agency may terminate a contract, without incurring liability, for the refusal of a nonstate entity to allow access to records as required by this section.
