Voidable Contracts: Spousal Consent and Conjugal Property Sales Under Philippine Law

The sale of a family's conjugal property by only one spouse raises serious legal questions. When a husband sells real property belonging to the conjugal partnership without his wife's consent, is the sale valid? Can a buyer who relied on a death certificate and court approval claim protection as a purchaser in good faith? The Supreme Court addressed these issues in Heirs of Ignacia Aguilar-Reyes v. Spouses Mijares (G.R. No. 143826, August 28, 2003), clarifying the rules on voidable contracts involving conjugal property.

The Facts of the Case

Vicente Reyes and Ignacia Aguilar-Reyes were married in 1960 but separated de facto in 1974. They owned a lot in Quezon City, purchased with conjugal funds, which was part of their conjugal partnership property. In 1978, Vicente entered into an installment agreement to sell the lot to Spouses Cipriano and Florentina Mijares for P110,000.00. Ignacia never gave her consent to this transaction.

In 1982, Vicente filed a petition in court claiming his wife had died. He presented a death certificate showing Ignacia died on March 22, 1982. The court appointed him guardian of their minor children and later authorized him to sell Ignacia's estate. On March 1, 1983, Vicente executed a deed of absolute sale over the property in favor of the Mijares spouses.

Ignacia later discovered the sale and filed an action for annulment in 1986, within the ten-year prescriptive period under the Civil Code. The trial court annulled the sale, but the Court of Appeals reversed, declaring the buyers as purchasers in good faith. The Supreme Court reversed the appellate court's ruling.

The Legal Issue: Void or Voidable?

Under the Civil Code, which governed the transaction, a husband could not alienate or encumber conjugal real property without his wife's consent. Article 166 of the Civil Code imposed this requirement. However, the absence of consent did not make the transaction void from the beginning. Instead, it made the contract voidable.

Article 173 of the Civil Code provided that the wife could, during the marriage and within ten years from the questioned transaction, ask the courts to annul any contract of the husband entered into without her consent. This distinction matters because a void contract is treated as if it never existed, while a voidable contract remains valid unless and until it is annulled.

The Supreme Court emphasized that this rule applies only to transactions governed by the Civil Code. For sales made after August 3, 1988, when the Family Code took effect, Article 124 of the Family Code now treats such dispositions as void if made without the consent of both spouses.

Annulment in Its Entirety

When a voidable sale of conjugal property is annulled, the entire transaction is set aside—not just the wife's share. The Supreme Court cited Bucoy v. Paulino to explain that the contract must be annulled in its entirety. The law does not limit annulment to the portion that prejudices the wife.

This rule is rooted in practical concerns. The conjugal partnership is liable for many obligations, and the property may be subject to debts. More fundamentally, the nullity is based on the lack of consent of an indispensable party to the contract. A husband cannot dispose of conjugal property without his wife's consent, and the courts will not allow such a transaction to stand in part.

Who Is a Purchaser in Good Faith?

A purchaser in good faith buys property without notice that another person has a right or interest in it, and pays full and fair price for the property. However, a buyer cannot close their eyes to facts that should put a reasonable person on guard and still claim good faith.

In this case, the buyers failed this test. The death certificate of Ignacia contained obvious flaws: it was issued by the civil registrar on March 10, 1982, but reported the death on March 4, 1982, and stated burial would occur on March 8, 1982—dates that were inconsistent and impossible. One of the buyers even admitted she asked for the death certificate because she suspected Ignacia was still alive.

The buyers also could not rely on the alleged court approval of the sale. The court orders appointing Vicente as guardian and authorizing the sale were issued in 1983, but the actual sale agreement was made in 1978—years before those orders existed. The subsequent deed of sale in 1983 was clearly an attempt to cure the absence of Ignacia's consent.

Practical Takeaways

• Spousal consent is essential. Under the Civil Code, a husband's sale of conjugal real property without the wife's consent is voidable, not void. Under the Family Code, such a sale is void. Either way, the transaction is vulnerable to annulment.
• Act within the prescriptive period. Under Article 173 of the Civil Code, the wife had ten years from the questioned transaction to seek annulment. The Family Code now requires the other spouse's consent or court authority, making unauthorized dispositions void.
• Buyers must exercise diligence. A buyer of conjugal property must verify the seller's authority and the other spouse's consent. Suspicious documents, such as a flawed death certificate, should trigger further investigation.
• Annulment affects the entire transaction. When a voidable sale is annulled, the whole contract is set aside, and the seller must return the purchase price received.
• Interest rates on refunds. When a sale is annulled and the seller must refund the purchase price, interest runs at 6% per annum from the filing of the complaint until the decision becomes final, then at 12% per annum until full payment.
