Mont. Code Ann. § 22-3-502

The people of Montana have an interest in preserving and protecting objects of scientific, historic, artistic, or cultural value and making them accessible to the public. The purpose of this part is to serve this interest by establishing a uniform procedure for lenders to preserve their interests in property loaned to museums; to require lenders to notify museums of changes of address and transfers of ownership of loaned property; and to vest title to unclaimed property in the museum that holds it.
