SPOUSES EULALIO CUENO AND FLORA BONIFACIO CUENO vs. SPOUSES EPIFANIO AND VERONICA BAUTISTA

The governing principle is that a sale of conjugal real property executed by the husband without the wife's consent under Article 166 of the Civil Code is merely voidable, not void ab initio. The Court held that the wife's exclusive remedy under Article 173 must be exercised during the marriage and within ten years from the questioned transaction. Failure to file the action within this strict prescriptive period validates the unauthorized sale, thereby extinguishing the wife's right to recover the property and binding subsequent purchasers who relied on the perfected transaction.

Lot No. 2836 was originally co-owned by Luis and Isidro Bonifacio. In 1961, petitioners Eulalio and Flora Bonifacio Cueno purchased Isidro's pro indiviso share, and Transfer Certificate of Title (TCT) No. T-20,676 was subsequently issued in the names of Eulalio and Flora's father, Luis Bonifacio. In December 1963, Eulalio executed an Escritura de Venta conveying his and Flora's conjugal share to Luis without securing Flora's written consent. The 1963 sale was registered concurrently with the 1967 title issuance, and TCT No. T-20,676 was cancelled and replaced by TCT No. T-20,677 issued solely to Luis. In August 1977, Luis sold the entire property to respondents, who took possession, constructed residential improvements, and later donated the lots to their children in 2005. Petitioners filed a complaint in 2008 alleging deprivation of their share through fraud and lack of spousal consent, seeking nullity of the 1963 sale, recovery of ownership, and cancellation of the respondents' titles.

• Lot No. 2836 was previously owned as co-owners by Luis and Isidro Bonifacio, who sold part of their interest to the City of Zamboanga and retained approximately 7,991 square meters.
• In 1961, petitioners purchased Isidro's pro indiviso share, and TCT No. T-20,676 was issued in 1967 in the names of Eulalio Cuenco and Luis Bonifacio.
• Prior to the title issuance, Eulalio executed an Escritura de Venta on December 4, 1963, selling his and Flora's conjugal share to Luis without Flora's consent.
• The 1963 sale was registered on April 13, 1967. TCT No. T-20,676 was cancelled, and TCT No. T-20,677 was issued solely in the name of Luis.
• On August 12, 1977, Luis executed a Deed of Absolute Sale conveying the entire property to respondents. TCT No. T-20,677 was cancelled, and TCT No. T-49,239 was issued to respondents.
• Respondents took possession, constructed houses, and continuously occupied the property. In 2005, respondents donated the lots to their four children, who obtained new certificates of title.
• Petitioners filed suit in 2008 claiming fraud and lack of spousal consent for the 1963 sale, seeking recovery of their ownership share, declaration of nullity of the 1963 sale and subsequent donation, and cancellation of the respondents' titles.
• The RTC found fraud unproven but invalidated the 1963 sale solely for lack of Flora's consent, holding the action imprescriptible and subsequent titles void. The CA reversed, holding respondents possessed superior rights as innocent purchasers for value relying on a clean Torrens title.

• Petitioner maintained that the 1963 sale executed by Eulalio was void ab initio under Article 166 of the Civil Code due to the absolute absence of Flora's marital consent, rendering the transaction legally inexistent.
• Petitioner argued that a void contract produces no legal effect and cannot serve as a source of rights, thereby invalidating all subsequent transfers, titles, and donations derived from the unauthorized conveyance.
• Petitioner contended that an action to declare the inexistence of a void contract does not prescribe, allowing them to recover their proprietary share despite the forty-five-year lapse.

• Respondent countered that they acquired the property in good faith and for valuable consideration from Luis, the registered owner, and were entitled to rely on the unencumbered face of TCT No. T-20,677.
• Respondent asserted continuous, open, and peaceful possession of the property for over three decades without any protest or objection from petitioners, establishing a superior possessory and ownership interest.
• Respondent maintained that petitioners' claims were barred by prescription and laches, and that the Torrens system protects innocent purchasers who rely on the face of a certificate of title free from annotations.

• Procedural Issues: Whether the petition improperly raises questions of fact not cognizable in a Rule 45 petition for review on certiorari, and whether the action to annul the 1963 sale has prescribed.
• Substantive Issues: Whether a sale of conjugal real property executed by the husband without the wife's consent under Article 166 of the Civil Code is void ab initio or merely voidable, and whether the wife's failure to file an action for annulment within ten years from the transaction's execution validates the conveyance.

• Procedural: The Court ruled that the petition did not improperly raise factual questions because the lower courts' findings on the execution and registration of the deeds were anchored on the presumption of regularity of public documents. More critically, the Court held that the action to annul the 1963 sale prescribed. Because the sale is merely voidable, the wife's statutory right to assail it under Article 173 of the Civil Code must be exercised during the marriage and within ten years from the transaction's execution. The 2008 complaint was filed forty-five years after the sale, rendering the action time-barred and foreclosing any recovery claim.
• Substantive: The Court definitively resolved a jurisprudential conflict by adopting the rule that a sale of conjugal property by the husband without the wife's consent under Article 166 of the Civil Code is merely voidable, not void. Reading Articles 166 and 173 in harmony, the Court held that the time-bound nature of the annulment remedy, the capacity to ratify, and the alternative statutory relief of demanding the property's value after the marriage's dissolution are fundamentally inconsistent with the characteristics of a void contract. The absence of spousal consent constitutes a lack of legal capacity under Article 1390, rendering the contract voidable until judicially annulled. Consequently, the 1963 sale remained valid and binding upon Flora's failure to timely seek annulment, thereby perfecting Luis's subsequent conveyance to respondents.

• Voidable Characterization of Unauthorized Conjugal Sales under the Civil Code — The Court established that a disposition or encumbrance of conjugal real property by the husband without the wife's consent under Article 166 of the Civil Code is merely voidable, not void. This doctrine requires harmonizing Articles 166 and 173, recognizing that the prescribed ten-year period for annulment, the possibility of ratification, and the alternative remedy of claiming the property's value demonstrate legislative intent to treat such contracts as valid until judicially annulled. The Court applied this to invalidate the petitioners' claim, holding that the wife's inaction for over four decades perfected the husband's unauthorized sale.
• Presumption of Regularity of Public Documents — The Court invoked the evidentiary rule that public documents enjoy a conclusive presumption of due execution and authenticity. Absent clear, convincing, and more than merely preponderant evidence of forgery or fraud, the presumption stands. The Court applied this to uphold the validity of the 1963 Escritura de Venta and the 1977 Deed of Absolute Sale, binding the petitioners to the lower courts' factual findings and foreclosing collateral attacks on the deeds' execution.

• "Where the law speaks in clear and categorical language, there is no room for interpretation — there is room only for application." — The Court deployed this maxim to strictly enforce the ten-year prescriptive period under Article 173, rejecting arguments to extend the reckoning period to the wife's discovery of the transaction and emphasizing that judicial legislation cannot override express statutory timelines.
• "Categorizing dispositions and encumbrances under Article 166 as void and thus imprescriptible would not only nullify Article 173 of the Civil Code but also render the limitations provided therein inutile." — This passage underscores the Court's statutory construction methodology, demonstrating that classifying unauthorized conjugal sales as void would directly contradict the explicit time-bound remedy and alternative relief provided by the legislature.

• Villocino v. Doyon — Cited as foundational precedent for the prevailing view that unauthorized conjugal sales under the Civil Code are voidable, not void, and subject to annulment exclusively under Article 173.
• Bucoy v. Paulino — Cited to illustrate the prior conflicting jurisprudence that characterized such contracts as void for lack of consent. The Court expressly abandoned this characterization to align with the voidable doctrine.
• De Leon v. De Leon — Cited to represent the abandoned contrary view that unauthorized conjugal sales are void ab initio for contravening mandatory law. The Court explicitly overturned this line of cases.
• Heirs of Christina Ayuste v. Court of Appeals — Cited to establish the strict rule that the ten-year period for annulment commences from the execution of the deed, not from the wife's discovery, and must be filed during the subsistence of the marriage.

• Article 166, Civil Code — Requires the wife's consent for the husband to alienate or encumber conjugal real property. The Court interpreted this as establishing a requirement of legal capacity, the absence of which renders the contract voidable rather than void.
• Article 173, Civil Code — Provides the exclusive remedy for the wife to seek annulment of an unauthorized conjugal contract within ten years during the marriage. The Court relied on its prescriptive and remedial limitations to classify the contract as voidable.
• Article 1409, Civil Code — Enumerates the grounds for void contracts. The Court noted that lack of spousal consent under Article 166 does not fall under these statutory categories, precluding a void classification.
• Article 1390, Civil Code — Governs voidable contracts. The Court analogized the husband's lack of capacity to alienate conjugal property without consent to the incapacity to give consent under this article, justifying the voidable characterization.
• Article 5, Civil Code — Declares acts executed against mandatory or prohibitory laws void, except when the law itself authorizes their validity. The Court held that Article 173's remedial framework operates as the statutory exception, preserving the contract's validity until annulled.

• Justice Perlas-Bernabe — Concurred, emphasizing that the time-bound nature of Article 173 and the alternative statutory remedy to claim the property's value after the marriage's dissolution are conceptually incompatible with the attributes of void contracts. She stressed that this voidable characterization applies strictly to marriages celebrated under the Civil Code regime, noting that the Family Code now expressly declares such unauthorized dispositions void ab initio to reflect modern gender equality principles.
