How Do Same-Sex Couples Prove Property Co-Ownership?
Introduction
Same-sex couples in the Philippines do not have a statutory property regime specifically governing their cohabitation. However, the absence of a same-sex marriage or partnership regime does not automatically prevent one partner from asserting ownership over property acquired during the relationship.
Recent Supreme Court jurisprudence recognizes that property rights may arise from actual joint contributions of money, property, or industry. The decisive question is not merely whether the parties lived together, but whether the claimant can establish a legally sufficient contribution to the acquisition, construction, or improvement of the property.
Governing Law on Unmarried Cohabitation
Article 148 of the Family Code applies to cohabitation that does not fall under Article 147. This includes relationships in which the parties are not legally capacitated to marry each other, including same-sex relationships under the present statutory definition of marriage.
Under Article 148, only property acquired by both parties through their actual joint contribution of money, property, or industry is owned in common. The parties’ corresponding shares are proportionate to their contributions, but their contributions and shares are presumed equal in the absence of proof to the contrary (Family Code, Article 148).
The rule differs from the regime under Article 147. Article 147 applies when a man and a woman who are capacitated to marry each other live exclusively as husband and wife without marriage or under a void marriage. In that situation, property acquired during cohabitation is generally presumed to have been obtained through joint efforts and owned in equal shares.
For same-sex couples, Article 148 governs because the parties are not legally capacitated to marry each other under the Family Code’s definition of marriage. The claimant therefore ordinarily must first establish actual contribution before the presumption of equal shares can arise.
The Supreme Court’s Recognition of Same-Sex Property Rights
In Josef v. Ursua, G.R. No. 267469, 2025, the Supreme Court held that a same-sex partner may establish co-ownership over property acquired during cohabitation by proving actual joint contribution.
The case involved an acknowledgment signed by one partner recognizing the other partner’s financial participation in the acquisition, construction, and improvement of the property. The Supreme Court treated the acknowledgment as evidence of actual contribution and concluded that the claimant was a co-owner.
The Court further ruled that the acknowledgment recognized at least a 50% share in the property. Because the respondent had admitted the claimant’s contribution, the respondent was estopped from later denying that contribution. Article 148 then supported the prima facie presumption that the parties’ shares were equal.
This ruling does not create a general marital property regime for same-sex couples. It instead confirms that ordinary rules on co-ownership, evidence, estoppel, and Article 148 may protect a same-sex partner whose contribution to the property is sufficiently established.
Requirements for Establishing Co-Ownership
A same-sex partner asserting ownership should generally establish the following:
First, the property must have been acquired during the parties’ cohabitation. The claimant should connect the acquisition, construction, or improvement of the property to the period when the parties lived together as a couple.
Second, there must be actual contribution. The contribution may consist of money, property, or industry. Financial payments are the clearest form of proof, but documented participation in construction, improvement, management, or other productive efforts may also be relevant when properly established.
Third, the contribution must be connected to the property. General claims that the parties shared household expenses or maintained a relationship are not necessarily sufficient. The evidence should show that the claimant’s money, property, or industry helped acquire, construct, preserve, or improve the particular asset.
Fourth, the claimant must prove the extent of the claimed share when it is disputed. Article 148 allows equal shares to be presumed once actual contribution is established, but evidence may show that the parties’ contributions and corresponding shares were different.
Evidence That May Support the Claim
Useful evidence may include bank records, deposit slips, loan documents, receipts, invoices, construction contracts, payment acknowledgments, property-related messages, sworn statements, and written admissions by the registered owner.
A signed acknowledgment may be especially important. In Josef v. Ursua, G.R. No. 267469, 2025, the Supreme Court relied on the respondent’s written acknowledgment of the claimant’s contribution and recognized the claimant’s 50% interest in the property.
Evidence should be organized chronologically and tied to particular payments or improvements. A bare assertion that the claimant “helped buy the property” is weaker than a payment record identifying the date, amount, recipient, and purpose of the payment.
Effect of an Admission or Acknowledgment
An admission may have consequences beyond ordinary evidentiary value. When a party expressly recognizes the other person’s contribution or ownership interest, that admission may support a finding of estoppel.
In Josef v. Ursua, G.R. No. 267469, 2025, the Supreme Court applied estoppel after finding that one partner had acknowledged the other partner’s contribution. The admitting party could not later take an inconsistent position and deny the contribution that had already been recognized.
The wording of the acknowledgment remains important. A document that recognizes a definite percentage or monetary interest is stronger than one that merely refers to emotional, domestic, or informal assistance. Ambiguous language must be read together with the entire document and the surrounding evidence.
Equal Shares Are Not Automatic at the Beginning
Article 148 does not automatically make every property acquired during a same-sex relationship jointly owned. The claimant must first show actual contribution to the acquisition or improvement of the property.
The Supreme Court in Josef v. Ursua, G.R. No. 267469, 2025, explained that if actual contribution is not proved, there is no co-ownership and no basis for the presumption of equal shares. Once actual contribution is admitted or established, however, the parties’ corresponding shares are prima facie presumed equal unless contrary evidence is presented.
This distinction is important. Cohabitation alone may establish the relationship between the parties, but it does not by itself establish ownership over every asset acquired by either partner.
Difference Between Article 147 and Article 148
Article 147 generally benefits parties who are a man and a woman, are capacitated to marry each other, and live exclusively as husband and wife without a valid marriage or under a void marriage. Property acquired through work or industry may be presumed to have been obtained through joint efforts, including household care and maintenance.
Article 148 applies to other forms of cohabitation, including relationships in which the parties are not capacitated to marry each other. It requires proof of actual joint contribution and generally limits ownership to the proportion of the parties’ proven contributions.
In Josef v. Ursua, G.R. No. 267469, 2025, the Supreme Court treated the parties’ same-sex relationship as falling under Article 148. The decision therefore rests on proof of contribution and not on an automatic marital or quasi-marital property regime.
Property Registered in Only One Partner’s Name
Registration in one partner’s name is relevant but may not conclusively defeat a properly supported claim of co-ownership. The claimant must still prove the contribution that allegedly created the ownership interest.
The title, deed of sale, loan documents, payment records, and other transactional documents should be examined together. If the claimant’s name does not appear on the title, proof of payment, construction expenses, or a written acknowledgment becomes particularly important.
A claim is substantially stronger when the registered owner previously acknowledged the other partner’s contribution or agreed to recognize a share in the property.
Property Acquired Through Construction or Improvement
Co-ownership claims are not limited to the purchase price of land or a finished structure. A claimant may assert an interest based on contributions to construction or substantial improvement, provided the contribution is proven and legally connected to the property.
Records should identify whether the claimant paid for materials, labor, architectural or engineering services, permits, renovations, taxes, insurance, or loan obligations. The legal assessment will depend on the nature of the contribution and the evidence linking it to the property’s acquisition or enhancement.
Practical Steps for Protecting the Claim
Partners who jointly acquire property should consider documenting their respective contributions before or during the transaction. A written agreement or acknowledgment should identify the property, the parties’ contributions, and the intended ownership shares.
Payments should preferably be made through traceable channels. Bank transfers, checks, electronic payment records, and receipts are generally easier to authenticate and connect to a specific transaction than cash payments without documentation.
Parties should also preserve communications concerning the purchase, construction, financing, and ownership of the property. Messages and emails may help explain the parties’ intent, although their admissibility and evidentiary weight will depend on the applicable rules and the circumstances of authentication.
If a dispute has already arisen, the claimant should gather the title, deed of sale, tax declarations, loan records, receipts, construction documents, photographs, messages, and affidavits of persons with personal knowledge of the contributions.
Limits of the Recent Ruling
The ruling in Josef v. Ursua, G.R. No. 267469, 2025, should not be read as recognizing same-sex marriage or establishing a general statutory property regime for same-sex couples. The Family Code provisions defining marriage and governing property regimes remain controlling unless changed by legislation or a later binding ruling.
The decision recognizes a property remedy based on proof of contribution, co-ownership principles, Article 148 of the Family Code, and estoppel. It does not mean that every same-sex partner is automatically entitled to one-half of all property acquired during the relationship.
Conclusion
Same-sex couples may assert property co-ownership rights in the Philippines, but the claim ordinarily depends on proof of actual contribution. Under Article 148 of the Family Code, the claimant must connect the contribution of money, property, or industry to the acquisition, construction, or improvement of the asset.
Josef v. Ursua, G.R. No. 267469, 2025, confirms that a clear written acknowledgment may establish actual contribution, support a finding of estoppel, and lead to recognition of an equal share when no contrary proof is shown.
The safest course is to document ownership arrangements from the outset, preserve proof of every contribution, and obtain legal advice before transferring, encumbering, or litigating over disputed property.
