To satisfy the recording provisions of sections 812 and 812‑A, with respect to land in the unorganized territory, the notice shall describe the land specifically or by reference to source of title, so as to identify it, and shall not be in the form of a reference to whatever land the person may own in the respective county or township. Such notice shall expire after 10 years but new notices, each effective for a 10-year period, may be so recorded at any time.   [PL 1979, c. 541, Pt. A, §138 (AMD).]
