Perfected Sales vs Contracts to Sell: Ownership Transfer and Good Faith in Property Disputes

The Supreme Court's 2010 decision in De Leon v. Ong (G.R. No. 170405) provides a clear lesson for property buyers and sellers: the language of a deed, not the parties' unspoken intentions, determines whether a transaction is a perfected sale or merely a contract to sell. The case also illustrates how good faith and actual possession resolve competing claims in a double sale.

The Facts of the Case

In March 1993, Raymundo de Leon sold three parcels of land in Antipolo, Rizal to Benita Ong for P1.1 million. The properties were mortgaged to Real Savings and Loan Association, Inc. (RSLAI). The parties executed a notarized deed of absolute sale with assumption of mortgage.

Under the deed, Ong paid P415,500 upfront and agreed to assume the outstanding loan balance of P684,500 with RSLAI. De Leon handed over the keys and authorized RSLAI to accept payments from Ong and release the certificates of title.

Ong made repairs and improvements. But she later discovered that De Leon had sold the same properties to another buyer, Leona Viloria, and had changed the locks. De Leon had also quietly paid off his loan and retrieved the certificates of title.

The Core Issue: Sale or Contract to Sell?

The central question was whether the parties entered into a contract of sale or a contract to sell. This distinction matters greatly:

• In a contract of sale, ownership transfers to the buyer upon perfection of the contract. If the buyer defaults, the seller may sue for the price or seek judicial rescission.
• In a contract to sell, ownership is retained by the seller until full payment. The buyer's failure to pay is a positive suspensive condition that prevents ownership from ever transferring.

De Leon argued that the sale was conditioned on RSLAI's approval of Ong's assumption of the mortgage. Since RSLAI never approved, he claimed no sale occurred.

The Supreme Court disagreed. The deed stated that De Leon sold the properties in a manner described as "absolute and irrevocable." Nothing in the document reserved ownership until full payment. The terms about payment merely affected how Ong would pay, not whether ownership transferred.

The Court applied the Civil Code rule that the execution of a notarized deed of sale is equivalent to delivery of the property. De Leon also handed over the keys and authorized RSLAI to release the titles—acts showing he had fully transferred ownership.

The Double Sale Rules

The Court also corrected the Court of Appeals on one point: the second sale to Viloria was not automatically void. Because the properties were sold twice by the same seller, the case fell under the rules on double sale under Article 1544 of the Civil Code.

Article 1544 provides that for immovable property, ownership belongs to the buyer who in good faith first recorded the sale in the Registry of Property. If neither recorded, the buyer who in good faith first took possession wins. If neither took possession, the buyer with the oldest title prevails—provided there is good faith.

Here, neither buyer registered the sale. Ong, however, took possession first: De Leon delivered the keys, and Ong made improvements. She was also a purchaser in good faith—she had no notice of any defect in De Leon's title other than the mortgage she agreed to assume.

The Role of Good Faith and Impossible Conditions

The Court also applied Article 1186 of the Civil Code: a condition is deemed fulfilled when the obligor voluntarily prevents its fulfillment. De Leon made Ong's obligation to assume the mortgage impossible by secretly paying off the loan himself. He could not benefit from his own obstruction.

Under Article 1266, Ong was released from her obligation to assume the loan because performance became impossible without her fault. However, the Court still ordered Ong to pay the P684,500 balance directly to De Leon, to avoid unjust enrichment.

Practical Takeaways

• The deed's language controls. If a notarized deed says the sale is "absolute and irrevocable," courts will treat it as a perfected sale unless the deed clearly reserves ownership.
• Notarized deeds transfer ownership. Under the Civil Code, a notarized deed of sale is equivalent to delivery—so get the deed registered promptly.
• In a double sale, register first. The buyer who registers in good faith first wins. If no one registers, prior possession in good faith decides.
• Bad faith disqualifies a buyer. A buyer who knows of another's claim cannot invoke the double sale rules.
• No one benefits from obstruction. A party who prevents a condition from happening cannot use that failure to escape obligations.
