12.1. Juridical acts creating servitudes, hypothecs, charges or similar provisions made in respect of ungranted land by or against the beneficiary of the letters patent or his predecessors cannot be invalidated on the sole ground that they were made in respect of ungranted land if the latter was alienated in accordance with the second paragraph of section 9.
The first paragraph applies, in respect of ungranted land, only to the land designated in the letters patent.
