When you and your partner buy property while living together without marriage, both of you can potentially claim ownership shares—even if the title or deed is registered in only one name. Philippine law does not recognize common-law marriage, so there is no automatic “spousal” community property. Instead, the Family Code provides clear rules for property acquired during cohabitation under what it calls “unions without marriage.”

The outcome depends on your specific situation: whether both of you were legally free to marry each other, whether you lived together exclusively as a couple, and what each person actually contributed. Many people in this situation successfully claim a share through negotiation or court action, but success requires understanding the rules and gathering the right evidence.

Legal Basis for Property Claims in Live-In Relationships

The governing rules are found in Articles 147 and 148 of the Family Code of the Philippines (Executive Order No. 209, 1987). These articles create a system of co-ownership for property acquired while the couple lives together.

Article 147 – The most common rule for typical live-in relationships

This applies when:

A man and a woman are both legally capacitated to marry each other (of legal age, no existing marriage, no other impediments).
They live exclusively with each other as husband and wife without the benefit of marriage (or under a void marriage).

Key rules under Article 147:

Wages and salaries earned during the cohabitation are owned in equal shares.
Property acquired through their work or industry is governed by the rules on co-ownership.
In the absence of proof to the contrary, properties acquired while they lived together are presumed to have been obtained by their joint efforts and are owned in equal shares.
A partner who did not directly pay for the property but performed household work, cared for the family, or maintained the home is deemed to have contributed jointly to its acquisition.
Neither partner may sell, mortgage, or otherwise encumber their share in the co-owned property without the other’s consent until the cohabitation ends.

This presumption is powerful in practice. Courts often uphold equal sharing when the couple held themselves out as partners and the property was bought during the relationship.

Article 148 – Stricter rule when there are legal impediments

This applies to cohabitation that does not fall under Article 147, such as when one partner is still legally married to someone else, or in other situations where the parties are not capacitated to marry each other.

Under Article 148:

Only properties acquired through actual joint contribution of money, property, or industry are co-owned.
Shares are in proportion to each person’s proven contribution.
In the absence of proof, contributions and shares are presumed equal.
Household work alone does not automatically create a share the way it does under Article 147.

A 2026 Supreme Court decision clarified that same-sex couples living together fall under Article 148 and can be recognized as co-owners upon proof of actual contribution.

Aspect	Article 147 (Typical live-in, both single)	Article 148 (One still married or other impediment)
When it applies	Both capacitated to marry; exclusive cohabitation as spouses	Legal impediment exists (e.g., existing marriage)
Presumption of equal shares	Strong – properties acquired during cohab presumed jointly owned	Weaker – only actual joint contributions count
Household/childcare work	Counts as joint contribution	Does not automatically create ownership share
Proof needed	Often relies on presumption + basic evidence of relationship	Requires clearer proof of money, property, or industry contributed
Protection against unilateral sale	Strong – consent required until cohabitation ends	Limited to proven share

Can Both Parties Actually Claim the Property?

Yes. The fact that the property is titled or deeded in only one partner’s name does not defeat a co-ownership claim. Philippine courts look beyond the certificate of title when co-ownership under the Family Code is properly proven or presumed.

In one Supreme Court case involving a same-sex couple, the Court granted partition even though the title was in only one name, relying on a signed acknowledgment and proof of contribution. Similar principles apply in heterosexual live-in cases under Article 147.

Properties acquired before the cohabitation began or after it ended generally remain the exclusive property of the person who acquired them. Gratuitous acquisitions (inheritance or donation given to only one partner) also remain separate.

Practical Steps to Claim Your Share

Many couples reach an agreement privately. When they cannot, the process usually follows these steps:

Document everything early. Gather proof of when the relationship started and ended, when the property was acquired, and what each person contributed. Photos, messages, utility bills in both names, joint bank records, affidavits from neighbors or family, and children’s birth certificates are commonly used.
Try amicable settlement first. Many disputes are resolved at the barangay level through mediation under the Katarungang Pambarangay (RA 7160). If both parties live in the same city or municipality, barangay conciliation is generally required before filing in court for property disputes. The Lupon will help facilitate an agreement. If successful, execute a notarized Deed of Partition or Agreement and register it with the Registry of Deeds.
If no settlement, file a case for partition in court. File a Complaint for Partition (often with accounting and damages) in the Regional Trial Court where the property is located. You can also annotate an adverse claim on the title while the case is pending to prevent the titled owner from selling or mortgaging the property without notice.
Court proceedings. The court will determine whether Article 147 or 148 applies, receive evidence, and decide the shares. If the property can be physically divided, it may order partition in kind. If not (most house-and-lot cases), it usually orders sale and division of proceeds. Commissioners may be appointed to handle the division.
Register the judgment. Once final, the court decision or partition agreement is registered with the Registry of Deeds to update the title or issue new titles reflecting the shares.

Typical timelines: Barangay mediation often concludes within 15–30 days if both cooperate. Full court cases for partition commonly take 1–3 years or longer, depending on court backlog, complexity, and whether appeals are filed. Acting promptly helps preserve evidence and witnesses.

Common Pitfalls and Real-Life Scenarios

Title in one name only. This is very common. The titled partner sometimes believes they own everything. The law protects the other partner’s share under the co-ownership rules, but you must assert it through evidence or court action.
One partner claims they paid 100%. Under Article 147 the presumption favors equal shares, and household contributions count. The other side must present strong contrary evidence to overcome the presumption.
Foreigner-Filipino live-in relationships. Foreigners generally cannot own private land in the Philippines (1987 Constitution, Article XII, Section 7). If land or a house-and-lot was acquired, the Filipino partner usually holds title. The foreigner may have a claim to improvements (the house/building) or reimbursement for contributions, but courts scrutinize arrangements that appear designed to circumvent constitutional restrictions. Condominiums have different rules (foreigners may own units subject to the 40% foreign ownership limit in the building). Always seek specialized advice in these cases.
One partner is still legally married. Article 148 applies. Proof of actual financial or industry contribution becomes more important, and the share may be smaller or limited.
Attempted sale or mortgage without consent. Under Article 147 this is not allowed until cohabitation ends. The non-consenting partner can seek to annul the transaction or claim damages.
Later marriage. If you later marry, property already co-owned from the live-in period does not automatically become absolute community property. It is usually best to formally partition or settle shares before marrying to avoid future disputes.

Documents, Offices, and Practical Realities

Helpful evidence to prepare:

Proof of cohabitation period (affidavits, photos, messages, joint bills, children’s documents)
Proof of property acquisition date and price (Deed of Sale, Transfer Certificate of Title, tax declarations)
Proof of contributions (bank statements, receipts, salary records, or evidence of household work)
Any written acknowledgment or agreement between the partners

Government offices involved:

Barangay Hall / Lupon Tagapamayapa – for mediation
Regional Trial Court (civil branch) – for partition cases
Registry of Deeds – for annotation of adverse claim and registration of partition
BIR – for any required taxes or clearances on transfer of shares (partition of co-owned property often has specific treatment; check current rules)
Local Assessor’s Office – for tax declarations and zonal valuation

Filing fees in court are based on the value of the property claimed. Lawyer’s fees vary widely depending on complexity and location. Notarization is required for agreements and many supporting documents.

Frequently Asked Questions

Can both live-in partners claim the property even if only one name is on the title?
Yes. Under Article 147 or 148, co-ownership can exist regardless of whose name appears on the title. Courts recognize shares based on the Family Code rules and evidence of the relationship and contributions.

Does housework or taking care of children count as a contribution to the property?
Under Article 147, yes. A partner’s efforts in caring for the family and household are expressly deemed joint contributions to property acquired during the cohabitation.

What proof do I need to show we were really in a live-in relationship?
Courts look at the totality of circumstances: how long you lived together, whether you held yourselves out as a couple, shared finances or responsibilities, had children together, and other indicators. Affidavits from neighbors, family, or friends, photos, messages, and official documents listing the same address are commonly accepted.

Is barangay mediation required before going to court?
In most cases, yes—if both parties reside in the same city or municipality. Property disputes are generally covered by the Katarungang Pambarangay law. You will need a Certificate to File Action from the barangay if mediation fails.

What if my partner tries to sell or mortgage the property without my consent?
Under Article 147, this is not permitted while you are still cohabiting. You can seek court intervention to stop the transaction or claim damages if it already happened. Annotating an adverse claim on the title provides public notice of your interest.

Do foreigners have the same rights in live-in relationships?
The co-ownership rules apply, but constitutional restrictions on land ownership create important limitations. A foreigner generally cannot own land. Claims are often limited to improvements or reimbursement, and arrangements must not violate the Constitution. Condominium units have separate rules.

If we later get married, what happens to property we bought while living together?
The property you already co-owned does not automatically convert into absolute community property. It is advisable to formally partition or document the shares before marrying to prevent future confusion or disputes.

How long do I have to claim my share after we separate?
While co-ownership exists, the right to demand partition generally does not prescribe. However, if one party clearly repudiates the co-ownership, a 10-year period from repudiation usually applies. Act reasonably promptly—evidence and witnesses become harder to secure over time.

Can we settle this privately without involving courts or barangay?
Yes. Many couples execute a notarized Deed of Partition or written agreement dividing the property. This is often faster and less expensive. Register the agreement with the Registry of Deeds if real property is involved.

Key Takeaways

Philippine law recognizes co-ownership of property acquired during live-in relationships through Articles 147 and 148 of the Family Code, even without marriage and even when title is in only one name.
Article 147 (most common for single couples living exclusively together) creates a strong presumption of equal shares, and household contributions count.
Article 148 applies stricter rules when legal impediments to marriage exist and requires proof of actual joint contributions.
The best first step is usually amicable settlement, often starting at the barangay level, followed by a notarized agreement.
When agreement is not possible, a court action for partition in the Regional Trial Court can enforce your rights.
Foreigners face additional constitutional limits on land ownership that require careful handling.
Acting with proper documentation and without unnecessary delay protects your position and makes resolution smoother, whether through agreement or court.

Understanding these rules empowers you to protect what you helped build during the relationship. Every situation has its own facts, so the specific evidence available in your case will determine the strongest path forward.
