The Supreme Court has clarified the rights and obligations of landowners and builders when a structure is mistakenly built on the wrong property. The ruling centers on Article 448 of the Civil Code, emphasizing that when a builder acts in good faith—believing they are constructing on their own land—the landowner must choose between appropriating the building by paying indemnity or compelling the builder to purchase the land. This decision protects the rights of both parties while seeking an equitable resolution to an inadvertent construction error.

Misplaced Foundations: Resolving Good Faith Construction on the Wrong Lot

This case revolves around a construction mishap in Los Baños, Laguna, where Miguel Castelltort unknowingly built his house on land owned by Rodolfo and Lily Rosales. Castelltort had purchased an adjacent lot from Lina Lopez-Villegas, relying on a faulty survey that misidentified the property boundaries. When the Rosaleses discovered the unauthorized construction, legal battles ensued, ultimately reaching the Supreme Court to determine the rights and obligations of all parties involved.

At the heart of this legal matter is the determination of whether Castelltort was a builder in **good faith**. According to the Civil Code, good faith is presumed, meaning Castelltort was considered to have acted under the honest belief that he was building on his own property unless proven otherwise. The Supreme Court emphasized that a builder in good faith is someone who builds with the belief that the land is theirs or that they have a right to build on it, unaware of any defects in their title. Article 527 reinforces this presumption by stating that good faith is always presumed, and the burden of proof rests on whoever alleges bad faith.

Several factors supported Castelltort’s claim of good faith. He had purchased the lot from Lopez-Villegas and even obtained a certified true copy of the title from the Registry of Deeds, which showed no prior adverse claims. Moreover, Lopez-Villegas’s representative, Rene Villegas, had pointed out the lot boundaries, and there were no apparent distinctions between the correct lot and the one where Castelltort built his house. This situation was further complicated by an error by the geodetic engineer’s employees, who misplaced the stone monuments marking the lot boundaries. The Supreme Court affirmed the Court of Appeals’ finding that both parties acted in good faith, at least until the Rosaleses notified Castelltort of their claim on August 21, 1995.

Given the finding of good faith, Article 448 of the Civil Code becomes relevant, providing a framework for resolving the dispute:

Art. 448. The owner of the land on which anything has been built, sown or planted in good faith, shall have the right to appropriate as his own the works, sowing or planting, after payment of the indemnity provided for in Articles 546 and 548, or to oblige the one who built or planted to pay the price of the land, and the one who sowed, the proper rent. However, the builder or planter cannot be obliged to buy the land if its value is considerably more than that of the building or trees. In such case, he shall pay reasonable rent, if the owner of the land does not choose to appropriate the building or trees after proper indemnity. The parties shall agree upon the terms of the lease and in case of disagreement, the court shall fix the terms thereof.

The Supreme Court underscored that the landowner has the option to either appropriate the building by paying the builder the value of the improvements or to compel the builder to purchase the land. This choice lies solely with the landowner, in accordance with the principle of accession, where the accessory follows the principal.

The Court clarified that Castelltort’s good faith ended on August 21, 1995, when he was informed of the Rosaleses’ title. Should the Rosaleses choose to appropriate the house, they must compensate Castelltort for the value of the improvements made until that date, reflecting the current fair market value as affirmed in *Pecson v. Court of Appeals*. Furthermore, Castelltort must pay a reasonable rent for the use of the land from August 21, 1995, until the property is transferred to the Rosaleses, whether through appropriation or compulsory sale. If parties cannot agree on terms, the court will set them.

This ruling reinforces the importance of verifying property boundaries before commencing construction. Landowners are advised to conduct thorough surveys and ensure clear demarcation to avoid similar disputes. For builders, obtaining necessary permits and conducting due diligence on property ownership are crucial steps to ensure they are building on the correct land. The decision also provides a clear legal framework for resolving disputes involving good faith builders, balancing the rights of both landowners and builders in an equitable manner. Finally, good faith possession does not last indefinitely; the law says it will be interrupted the moment defects in the title are made known to the possessor, by extraneous evidence or by suit for recovery of the property by the true owner.
