Identity of land; proof of title; recovery of ownership

It has been said that, in determining the limits of a piece of land, boundary owners cannot be relied upon. Unlike natural boundaries like rivers and streams, boundary owners are likely to change and a corresponding change in the limits of the property may occur.[4] In Cinco v. Bartolome, as cited above, TD No. 18610 was issued way back in 1949, and its description of the lot's boundaries was based on the named boundary owners in the 1947 Partition Agreement. The intervening period of more than four decades from the issuance of TD 18610 and the filing of the Complaint should have cautioned the commissioner that the description of boundaries in Catalina's Tax Declarations was already inaccurate. Without any explanation, the commissioner still preferred the description in Catalina's old Tax Declarations over the official results of the cadastral survey in 1976. Given these facts, Catalina's argument that the description in her Tax Declarations must be rejected; the sketch provided by the commissioner cannot be held sufficient to establish the identity of her lot.
