In Philippine law, the conjugal or community property regime imposes strict requirements on the alienation or encumbrance of assets acquired during marriage. The sale of such property without the written consent of both spouses is generally null and void, reflecting the principle of joint administration and the protection of the marital partnership. This rule applies uniformly across the two primary property regimes and has been reinforced by decades of jurisprudence emphasizing spousal equality and the indivisible nature of conjugal ownership.

Property Regimes Governing Conjugal Assets

Philippine marriage law recognizes several property regimes, determined by the date of marriage and any marriage settlement executed before the wedding.

Absolute Community of Property (ACP): The default regime for marriages celebrated on or after 3 August 1988 (Article 75, Family Code). Under ACP, all properties acquired by either or both spouses during the marriage belong to the community, regardless of whose name appears on the title or who acquired them, except for exclusive properties listed in Article 92 (e.g., property brought into the marriage, gratuitous acquisitions, or personal effects).
Conjugal Partnership of Gains (CPG): The regime applicable to marriages before 3 August 1988, unless a different regime was chosen. Under CPG, only properties acquired onerously during the marriage form part of the partnership (Article 116, Family Code, applying the Civil Code framework for pre-1988 marriages). Fruits and income of separate properties also belong to the partnership.
Other regimes: Complete separation of property or any other regime stipulated in a valid marriage settlement removes the conjugal character entirely; each spouse may freely dispose of his or her own assets without consent.

The character of property as conjugal or community is presumed when acquired during marriage (Articles 93 and 116). Even if registered solely in one spouse’s name under the Torrens system, the property remains conjugal if it falls within the definition. The certificate of title does not convert conjugal property into separate property.

Legal Provisions on Disposition and Administration

The core rules are found in two parallel provisions of the Family Code:

Article 96 (ACP): “The administration and enjoyment of the community property shall belong to both spouses jointly. … In the event that one spouse is incapacitated or otherwise unable to participate in the administration of the community property, the other spouse may assume sole powers of administration. These powers do not include disposition or encumbrance without authority of the court or the written consent of the other spouse. In the absence of such authority or written consent, the disposition or encumbrance shall be void.”
Article 124 (CPG): Identical wording applies to the conjugal partnership.

Both articles expressly prohibit disposition or encumbrance (sale, mortgage, donation inter vivos, lease beyond one year, etc.) without the written consent of the other spouse or prior court authority. The prohibition is absolute for acts that transfer ownership or create real rights over the property.

For marriages governed by the Civil Code (pre-1988), Article 166 of the old Civil Code similarly required the wife’s consent for the husband to alienate or encumber conjugal real property. The husband’s sole administration did not extend to unilateral sales of realty.

Consequences of Selling Without Consent

A sale executed by only one spouse without the other’s written consent or court authority is null and void ab initio. No title passes to the buyer, even if the buyer pays full consideration and registers the deed. The property remains part of the conjugal or community estate, and the non-consenting spouse (or the partnership itself) may recover it from the buyer or any subsequent transferee who is not a purchaser in good faith and for value without notice.

The Supreme Court has consistently ruled that the consent of both spouses is indispensable because the conjugal property belongs to the partnership, not to the individual selling spouse. The transaction produces no legal effect as against the non-consenting spouse’s interest.

The Continuing-Offer Doctrine

Although the disposition is void, the law treats the contract as a continuing offer on the part of the consenting spouse and the third-party buyer. The offer may be perfected into a binding contract if:

the non-consenting spouse later gives written consent (ratification), or
the court grants authority before the offer is withdrawn.

Ratification must be express and written; implied ratification or mere inaction does not suffice. The continuing-offer rule prevents the void contract from being treated as wholly nonexistent for all purposes and allows equity to intervene when justice requires.

Exceptions and Court-Authorized Dispositions

The prohibition is not absolute. Recognized exceptions include:

Exclusive or separate property: A spouse may freely sell property that is his or her own (brought into marriage, inherited, or acquired gratuitously) without consent.
Court authority:
- When one spouse is absent, judicially declared absent, incapacitated, or confined (Articles 97–101 for ACP; Articles 125–128 for CPG). The present spouse may petition the court for sole administration and authority to sell.
- When the other spouse unjustly refuses consent and the sale is necessary for the family’s support, business needs, or other legitimate purposes. Courts may grant authority after hearing both sides.
- In cases of abandonment: The abandoned spouse may petition for sole administration (Article 101 for ACP) and thereafter seek court approval for specific dispositions.
Legal separation, annulment, or declaration of nullity: Upon finality of a decree, the absolute community or conjugal partnership is dissolved and liquidated. Thereafter, each spouse owns a determinate share and may sell it without the other’s consent.
Donations mortis causa or sales in the ordinary course of a business operated by one spouse with the other’s implied acquiescence (limited application; major assets still require consent).

Protection of Third Parties

A buyer who acts in good faith and for value, without knowledge or notice that the property is conjugal and that consent is lacking, may be protected under the rules on innocent purchasers. However, because the sale is void, the buyer generally acquires no title and must return the property. The buyer’s remedy is to seek reimbursement of the purchase price plus interest from the selling spouse personally or from the conjugal funds if the proceeds benefited the partnership. If the buyer registers the sale and the non-consenting spouse fails to annotate a claim, estoppel or laches may occasionally bar recovery, but the void character of the sale itself remains.

Remedies Available to the Aggrieved Spouse

The non-consenting spouse (or heirs after death) may file:

An action for declaration of nullity of the sale (imprescriptible because the contract is void).
Reconveyance or recovery of the property.
Annulment of title issued to the buyer.
Damages against the selling spouse and the buyer if bad faith is proven.
Preliminary injunction or lis pendens annotation to prevent further transfer during litigation.

If the selling spouse has dissipated the proceeds, the aggrieved spouse may charge the selling spouse’s share upon liquidation with the corresponding indemnity.

Prescription and Procedural Notes

Actions to declare the nullity of a void sale do not prescribe. However, the five-year period mentioned in Articles 96 and 124 refers only to recourse against the husband’s unilateral administrative decision, not to the nullity of a disposition. Claims for reimbursement of the purchase price by the buyer may prescribe under ordinary rules (10 years for written contracts).

In practice, the action is usually filed in the Regional Trial Court of the place where the property is located (real action) or where the spouses reside (personal action for damages).

Special Situations

Death of a spouse: The surviving spouse cannot unilaterally sell the entire conjugal property. Liquidation must precede any disposition; the heirs of the deceased acquire rights to the decedent’s share.
Minor children: The surviving parent or guardian must obtain court approval for sales affecting the children’s presumptive legitime.
Business properties: If one spouse operates a business with the other’s knowledge, sales of inventory or movables in the ordinary course may be upheld, but capital assets and real property remain subject to the consent rule.
Pre-1988 marriages: The husband’s traditional administrative role under the Civil Code does not allow unilateral sale of real property; the same nullity rule applies.

The Family Code’s emphasis on spousal equality has eliminated earlier distinctions that gave the husband broader powers. Today, both regimes treat disposition as a joint act requiring mutual consent or judicial intervention.

This framework—rooted in Articles 96 and 124 of the Family Code and parallel Civil Code provisions—ensures that conjugal property remains protected from unilateral depletion. Any sale lacking the required consent is void, subject only to the continuing-offer mechanism and narrow exceptions where court authority substitutes for consent. The rule safeguards the marital partnership while providing equitable relief when circumstances justify judicial intervention.
