Protecting Marital Property When a Spouse’s Signature Matters

A forged special power of attorney cannot defeat conjugal property rights. Learn the rules on spousal consent in property sales.



A sale of conjugal property without the genuine consent of both spouses is void. In Titan Construction Corporation v. David (G.R. No. 169548, March 15, 2010), the Supreme Court protected a husband’s share of a conjugal lot sold by his wife using a forged special power of attorney (SPA). The case clarifies how courts treat spousal consent, forged documents, and claims of being a “buyer in good faith.”

The Facts of the Case

Manuel and Martha David married in 1957. In 1970, they acquired a lot in White Plains, Quezon City. The title was registered in Martha’s name, with a notation that she was “married to Manuel A. David.” The spouses separated de facto in 1976.

In 1995, Manuel discovered that Martha had sold the property to Titan Construction Corporation for P1.5 million. Titan relied on an SPA dated January 4, 1995, purportedly signed by Manuel, authorizing Martha to sell the property. Manuel claimed the SPA was a forgery and filed a complaint to annul the sale and recover the property.

The Issue

The central question was whether the sale was valid despite the absence of Manuel’s genuine consent. Titan argued it was a buyer in good faith and for value, relying on the notarized SPA. Manuel insisted the SPA was spurious and that the sale was void.

The Ruling: Conjugal Property Requires Both Spouses’ Consent

The Court ruled in favor of Manuel. The property was conjugal because it was acquired during the marriage using conjugal funds. Under the Civil Code, which governed the marriage, all property acquired during the marriage is presumed conjugal unless proven otherwise. Titan failed to overturn this presumption.

Because the property was conjugal, the sale required Manuel’s consent. Under Article 124 of the Family Code, any disposition of conjugal property without the written consent of the other spouse is void. The SPA purportedly giving Martha authority to sell was a forgery, so no valid consent existed.

The Forged SPA and the “Buyer in Good Faith” Defense

The Court rejected Titan’s claim of good faith. The SPA was notarized, which normally creates a presumption of authenticity. However, clear and convincing evidence overcame that presumption: an expert witness testified the signature was not Manuel’s, and Manuel categorically denied signing it.

Several red flags should have alerted Titan to the SPA’s dubious nature:

  • The SPA lacked Manuel’s residence certificate details, while Martha’s were complete.
  • The SPA was never registered with the Register of Deeds, as required by Section 64 of Presidential Decree No. 1529.
  • The SPA was unnecessary since the spouses lived on the same street.
  • Titan’s own agent testified that Titan’s vice president asked why Manuel’s name did not appear on the deed of sale.
  • Titan gave Martha P500,000 without seeing the property, the title, or the SPA—hardly the conduct of a prudent buyer.

Practical Takeaways

  • Conjugal property cannot be sold by one spouse alone. The written consent of both spouses is required for any disposition or encumbrance of conjugal property. Without it, the sale is void.
  • A notarized document is not conclusive. Notarization creates a presumption of authenticity, but that presumption can be overcome by clear and convincing evidence, including expert testimony on forgery.
  • Buyers must exercise due diligence. A buyer who ignores red flags—such as missing details in a power of attorney or a title indicating the seller is married—cannot claim protection as a buyer in good faith.
  • Verify the authority to sell. Before purchasing property from a married person, check whether the title reflects a marriage and whether the seller has the other spouse’s genuine, written consent.
  • Raise claims promptly. A party who fails to file a cross-claim for reimbursement cannot later demand it on appeal. Titan was allowed to pursue a separate action against Martha, but only because the Court declined to bar it outright.
