Wrong lot number does not invalidate land sale, Supreme Court rules

A deed can be ‘reformed’ if buyers and sellers can prove their original agreement.

A sale of land remains valid even if the deed of sale identifies the property incorrectly, as long as the parties’ true agreement can be clearly proven, the Supreme court ruled.

In a Dec. 3, 2025, decision (G.R. No. 266298) written by Associate Justice Henri Jean Paul Inting—and published on the SC website on July 24—the high court ruled in favor of buyers Genara and Felipe Abay Sr., who purchased a 491-square-meter property in Cebu City in 1982.

Before the sale, seller Crispin Caballes and Tomas Gallardo, one of the heirs of Trinidad Caballes-Gallardo, personally showed the Abays the property’s boundaries. The couple later fenced the land—with Tomas’ help—paid real property taxes, and openly occupied it for about 20 years.

The dispute began when workers of another couple, Jacinto and Chiok Ngo Lim Young, entered the property, destroyed the Abays’ fence, and built their own posts. The Abays later discovered that a title over the property had been issued in the Youngs’ names, prompting them to file a case before the Regional Trial Court in 2012 to cancel the title.

The Gallardos challenged the Abays’ claim, arguing that their documents referred to Lot No. 6036-B and not Lot No. 7, the property they were occupying. While both lots were in the same area, they were separate properties and not beside each other.

The RTC ruled in favor of the Abays, upholding the 1982 sale involving the shares of Crispin and his siblings. It also found that the Youngs should have investigated the property’s status before buying it.

In 2023, however, the Court of Appeals reversed the RTC’s decision, ruling that the documents presented by the Abays showed they purchased Lot No. 6036-B and not Lot No. 7.

The SC later reinstated the RTC ruling, finding that the reference to Lot No. 6036-B in the deeds was only a clerical error. Evidence showed that both buyers and sellers intended to transfer the property the Abays had identified, occupied, and possessed for years.

The SC stressed that people usually buy a property based on what they see on the ground, such as its boundaries, landmarks, and improvements—not just its technical lot number.

A contract may be “reformed” when three conditions are met: the parties agreed to the transaction; the written document fails to reflect their true agreement; and the error resulted from a mistake, fraud, accident, or unfair conduct. The SC found that all three conditions were present in the Abays’ case.

First, the 1979, 1981, and 1982 deeds confirmed the parties’ agreement to the sale. Second, Crispin and Tomas showed the Abays the land they bought, which the couple fenced, paid taxes on, and occupied for 20 years. Tomas’ help in building the fence further showed he recognized the sale. Third, the lot number error happened because the land was still part of a larger estate and had no separate title at the time.

The SC also ruled that the Youngs were not buyers in good faith, as the Abays had already occupied and fenced the property years before the purchase.

Legal experts have long cautioned that errors in land documents can lead to costly disputes, especially in areas where untitled properties, inherited estates, and incomplete surveys remain common. While the SC decision protects buyers and sellers affected by documentation mistakes, it does not excuse negligence.

The SC stressed that parties must still present convincing evidence proving their true agreement, while prospective buyers remain responsible for inspecting properties and verifying ownership before completing a purchase.
