Proving Simulation of Property Sales: The Burden on Those Who Impugn a Deed

The Supreme Court has long held that a notarized deed of sale carries a presumption of regularity. But when a family member claims the sale was fictitious—a mere scheme to hold property in trust—who must prove the simulation? In Ramos v. Heirs of Honorio Ramos Sr. (G.R. No. 140848, April 25, 2002), the Court laid down clear guideposts: the party impugning a contract's validity bears the burden of proof, and family ties alone do not establish simulation.

The Case: A Family Dispute Over Lot 2961

In 1954, Salud Abejuela executed a Deed of Absolute Sale over Lot 2961 in Cagayan de Oro City in favor of her son, Ramon Ramos. The deed was notarized and registered. After Salud's death in 1966 and her husband Lucio's death in 1974, Ramon occupied the lot, harvested coconuts from it, and paid realty taxes in his name.

In 1991, the heirs of Ramon's brother, Honorio Ramos Sr., filed suit. They claimed the sale was simulated—that Salud intended the lot to be held in trust and divided equally between Ramon and Honorio. They pointed to the mother-son relationship, the allegedly low price of P1,000, and Ramon's lack of income in 1954 as badges of simulation.

The trial court dismissed the complaint, but the Court of Appeals reversed, citing several "badges of simulation." The Supreme Court reversed the appellate court, reinstating the trial court's dismissal.

The Burden of Proof in Alleged Simulation

The Court reiterated a fundamental rule: the burden of proving simulation falls on those who impugn the contract's regularity and validity. A duly executed contract carries the presumption of validity, and this presumption can only be overturned by strong, competent, and conclusive proof.

The primary consideration in determining whether a contract is simulated is the intention of the parties, as shown by the express terms of the agreement and their contemporaneous and subsequent acts. When parties have no intention to be bound at all, the contract is absolutely simulated and void under Articles 1345, 1346, and 1409 of the Civil Code. But when they merely conceal their true agreement, the contract is not completely void—they are bound to their real agreement, provided it is not contrary to law, morals, or public policy.

What Does Not Prove Simulation

The Court rejected several circumstances the respondents cited as badges of simulation:

Family relationship. Mere consanguinity between vendor and vendee does not prove lack of intention to be bound. Not all contracts between family members are fictitious.

Low price. Without evidence of the lot's fair market value in 1954, there was no basis for claiming the price was too low.

Failure to present a contra documento. The respondents claimed a secret document existed showing the sale was a sham, but they failed to produce it. The testimony of a witness who allegedly saw it was inadmissible under the best evidence rule (Section 2, Rule 130 of the Rules of Court), which requires the original writing itself.

Allegations of co-ownership in a prior case. The mere fact that Honorio was impleaded as a co-defendant in an earlier partition case did not confer co-ownership. Under the Rules of Court, a person whose consent as co-plaintiff cannot be obtained may be impleaded as a defendant.

The "Protuberant Index" of Simulation

The Court distinguished this case from Suntay v. Court of Appeals (251 SCRA 430, December 19, 1995). In Suntay, the most striking index of simulation was not the relationship between the parties, but the complete absence of any attempt by the buyer to assert rights of dominion over the property.

Here, the evidence showed the opposite. Ramon hired tenants to care for and harvest the coconuts on Lot 2961. He declared the property for taxation and paid realty taxes in his name. When Honorio was asked to share in paying disturbance compensation to a tenant who mistakenly planted on the lot, he refused—an act inconsistent with a claim of co-ownership.

The Court also applied laches and estoppel. The respondents' predecessors had the opportunity to assert their claim during the settlement of Salud's estate but failed to do so. Having passed up that chance, they could not later claim ownership.

Practical Takeaways

• A notarized deed of sale is presumed valid. Anyone claiming it is simulated must present clear and convincing evidence, not mere speculation or family circumstances.
• Family ties do not equal simulation. Courts look to the parties' actual conduct—who possessed the property, who paid taxes, who harvested its fruits—not just their relationship.
• A contra documento is crucial. If a party claims a secret document exists, they must produce the original or explain its absence under the best evidence rule; hearsay testimony about it will not suffice.
• Acts of dominion matter. The buyer's exercise of ownership rights—occupying the land, collecting rents, paying taxes—is the strongest evidence that the sale was genuine.
• Delay can be fatal. Failure to assert a claim at the earliest opportunity, especially during estate settlement, may result in laches and estoppel.
