From and after June 1, 1927, any instrument conveying real estate in the county whereby the same is conveyed to a trustee, to be held by him in trust to secure a debt therein described and commonly known as a deed of trust, shall be executed and may be acknowledged and recorded in the same manner as an absolute deed; and shall be valid as a security for any debt mentioned and described in such instrument. The clerk of the circuit court of the county shall be required to record deeds of trust in the same manner as that in which absolute deeds are now recorded; and, provided further, that in order to assign or transfer title to any evidence of debt secured by such deed of trust it shall not be necessary to record any form of assignment or transfer. (Mont. Co. Code 1965, § 8-1; 1927, ch. 493, § 184.)
