If you and your partner are not married but want to purchase a house, lot, or condominium together in the Philippines, you can legally become co-owners of real property. The rules that apply, however, are different from those for married couples, and they depend on your specific circumstances—whether both of you are Filipino citizens, whether one of you is a foreigner, and whether you are both legally free to marry each other. This article walks you through the legal framework, your practical options, how to register ownership properly, what happens if the relationship ends or one partner passes away, and the steps that help ordinary couples protect their investment and avoid expensive disputes.

Legal Framework: Property Relations for Unmarried Couples

Philippine law recognizes co-ownership of real property by unmarried couples primarily through two provisions in the Family Code of the Philippines (Executive Order No. 209) and the general rules on co-ownership in the Civil Code.

Article 147 applies when a man and a woman who are both capacitated to marry each other (neither is married to someone else and there are no legal impediments) live exclusively together as husband and wife without the benefit of marriage, or under a void marriage. In these cases:

Wages and salaries are owned in equal shares.
Property acquired by both through their work or industry is governed by the rules on co-ownership.
There is a legal presumption that properties acquired while they lived together were obtained through joint efforts, work, or industry and are owned in equal shares.
A partner who handled household and family care is considered to have contributed jointly to the acquisition of property.
Neither partner may encumber or sell their share in the co-owned property by acts inter vivos (while alive) without the other’s consent until the cohabitation ends.

Article 148 applies in all other cases of cohabitation where the partners are not capacitated to marry each other—for example, when one or both are still legally married to someone else, or in relationships where marriage between them is prohibited. Here, only properties acquired through the actual joint contribution of money, property, or industry are owned in common, and shares are proportional to proven contributions. There is no presumption of equal ownership or automatic credit for homemaking efforts.

In February 2025 (publicized in 2026), the Supreme Court in Jennifer C. Josef vs. Evalyn G. Ursua (G.R. No. 267469) clarified that Article 148 governs same-sex couples living together, as they cannot legally marry under current law. The Court recognized co-ownership based on proof of actual financial contributions, even when the property title was registered in only one partner’s name, and ordered partition of the house and lot.

These Family Code rules work together with the Civil Code provisions on co-ownership (Articles 484–501). Co-owners hold undivided (pro-indiviso) shares. Each may use the entire property without prejudicing the others and must share in the benefits and maintenance expenses in proportion to their interest. In case of doubt, shares are presumed equal unless proven otherwise or specified in a deed or agreement.

How Co-Ownership Differs from Marriage

Married couples are generally under the absolute community of property regime (or conjugal partnership of gains if they married before the Family Code took full effect and had no prenup). Almost everything acquired during marriage becomes common property, with strong presumptions and protections.

Unmarried couples do not enjoy these automatic marital presumptions. Protection comes instead from:

The specific Family Code article that fits your situation (147 or 148).
Clear documentation of contributions.
Having both names on the title when possible.
A well-drafted written agreement.

Practical Steps to Buy and Register Property as Co-Owners

Assess your situation and property type. Determine whether Article 147 or 148 likely applies. Decide between a house-and-lot (land ownership is restricted for foreigners) or a condominium unit (more flexible for mixed-nationality couples).
Agree on contributions and shares early. Discuss and document who will pay the down payment, monthly amortizations, renovations, and ongoing expenses. Decide whether shares will be equal or proportional to actual contributions.
Execute a written co-ownership or property agreement. Have a lawyer draft a notarized agreement that states each person’s contribution, intended ownership percentage, how expenses will be shared, what happens if you separate or one dies, and a right of first refusal if one wants to sell their share. This document is invaluable evidence later.
Prepare and sign the purchase documents. The Deed of Absolute Sale (or Contract to Sell followed by a Deed) should name the qualified buyers. If both are Filipino and qualified under Article 147 or 148, both names can appear as vendees. Specify shares if they are not equal. Have the deed notarized.
Pay taxes and secure the electronic Certificate Authorizing Registration (eCAR) from the Bureau of Internal Revenue (BIR). The seller usually shoulders the 6% Capital Gains Tax (based on the higher of the selling price or BIR zonal value). Documentary Stamp Tax is 1.5%. Local transfer tax (paid to the city or municipal treasurer) and registration fees follow. Processing the eCAR typically takes 5–15 working days once documents are complete.
Register the deed with the Registry of Deeds. Submit the notarized deed, eCAR, tax declarations, real property tax receipts, and other required papers. The Registry of Deeds will issue a new Transfer Certificate of Title (TCT) for land or Condominium Certificate of Title (CCT) for a condo unit, showing both names as co-owners (or the single qualified owner with appropriate annotations). Registration usually takes 15–45 days after the eCAR is issued, depending on the office’s workload and completeness of submissions.

Typical total transfer costs (beyond the purchase price) often range from 8–12% of the property’s value, though exact amounts vary by location, zonal value, and who shoulders which tax. Always verify current rates directly with the BIR and local government offices, as they can change.

When Both Partners Are Filipino Citizens

You have the most flexibility. You can register the property in both names as co-owners. The title will reflect your civil status (usually “single” or “of legal age”) and indicate co-ownership. This setup makes future partition or sale much simpler because ownership is already of public record.

When One Partner Is a Foreigner

A foreigner cannot own private land in the Philippines under Article XII, Section 7 of the 1987 Constitution. The land title must be registered solely in the name of the Filipino partner. Attempts to place the foreigner’s name on the title or use simulated arrangements to circumvent the rule are void and can expose the parties to legal risks, including possible cancellation of title or escheat proceedings.

The foreigner may own the building or improvements constructed on the land (subject to Civil Code rules on accession), but this creates practical complications because buildings are attached to the land. Many couples in this situation:

Title the land exclusively in the Filipino partner’s name.
Execute a detailed notarized agreement that clearly records the foreigner’s financial contributions toward the purchase, construction, or improvements.
Consider purchasing a condominium unit instead, where a foreigner may legally own the unit (subject to the 40% foreign ownership limit per condominium project under the Condominium Act).

Long-term land leases (generally up to 50 years, renewable for another 25 years under certain investment laws) are another option, with the Filipino partner owning the land and the foreigner leasing it. These arrangements require careful drafting and registration.

Strongly recommended: Consult a Philippine lawyer experienced in property law and foreign ownership restrictions before signing any purchase documents or agreements. Courts will not create an implied trust in favor of a foreigner that effectively allows land ownership in violation of the Constitution.

What Happens If You Separate

If you both agree, you can sell the property and divide the proceeds according to your ownership shares or agreement, or one partner can buy out the other through a Deed of Partition or Quitclaim Deed (which may still trigger taxes).

If you cannot agree, any co-owner has the right to demand partition under the Civil Code. This can be done amicably or through a court case filed in the Regional Trial Court where the property is located. The court may order physical division (rare for a typical house and lot) or, more commonly, sale of the property with division of the proceeds. The process involves presenting evidence of co-ownership and contributions. Court cases can take one to several years and involve legal fees, commissioner’s fees, and publication costs. A clear written agreement with a dispute-resolution clause (such as mediation) can help avoid or shorten litigation.

What Happens If One Partner Passes Away

An unmarried partner has no automatic inheritance rights like a legal spouse. The deceased partner’s share in the co-owned property forms part of his or her estate and passes to compulsory heirs (children, parents, or other relatives) according to the rules on succession in the Civil Code—either by will (testate) or by operation of law (intestate).

The surviving co-owner retains his or her own share but now co-owns the property with the deceased’s heirs. Further partition or buy-out negotiations with the heirs may be necessary. To provide for your partner, each of you should consider executing a will that disposes of your share (subject to the legitime or reserved portion that must go to compulsory heirs). A holographic will (entirely handwritten, signed, and dated by the testator) is valid in the Philippines, or you can have a notarial will prepared by a lawyer.

Common Pitfalls and How to Protect Yourself

Many couples run into problems because they rely on verbal promises, put everything in one person’s name without documentation, or fail to plan for the end of the relationship or death. Under Article 148 (or when proof is weak under Article 147), it can be difficult to establish co-ownership without receipts, bank records, or a written agreement. Mixed-nationality couples sometimes discover too late that the foreigner cannot be on the land title. Later marriage can also change the property regime and create new issues that require legal review.

Best practices:

Get everything in writing and notarized as early as possible.
Keep meticulous records of all payments and contributions.
Put both qualified names on the title whenever possible.
Have a lawyer review or draft key documents rather than relying solely on real estate brokers or developers.
Discuss and document what should happen in case of separation, serious illness, or death.

Frequently Asked Questions

Can unmarried or live-in partners legally buy and own real property together?
Yes. You can acquire property as co-owners under the Civil Code and, when applicable, Articles 147 or 148 of the Family Code. The strength of your rights depends on proper documentation and registration.

Is ownership automatically 50-50?
Under Article 147 there is a presumption of equal shares for properties acquired during cohabitation through joint efforts. Under Article 148, shares are strictly proportional to proven actual contributions. You can (and should) specify shares in the deed or a separate agreement.

What if the title ends up in only one partner’s name?
You may still claim co-ownership if you can prove the property falls under Article 147 or 148 and that you made actual contributions. However, having both names on the title from the start provides the strongest and simplest evidence.

Can a foreigner and a Filipino unmarried couple own land together?
The foreigner cannot own land. The title must be in the Filipino partner’s name only. The foreigner can contribute to the purchase or improvements and document those contributions in a notarized agreement, but this does not create legal land ownership for the foreigner. Condominium units or long-term leases are often more suitable options.

How do we divide the property if we break up?
You can agree to sell and split the proceeds or have one buy out the other. If you cannot agree, any co-owner may file an action for partition in court. A written agreement made while you are still together makes this process much smoother and less expensive.

Does the surviving partner automatically inherit everything if one dies?
No. The surviving unmarried partner keeps only his or her own co-ownership share. The deceased’s share goes to the deceased’s legal heirs. A will can help direct your share to your partner, but it cannot deprive compulsory heirs of their legitime.

Do we really need a separate co-ownership agreement?
It is not strictly required by law, but it is one of the most effective ways to protect both parties, clarify shares and responsibilities, and reduce the risk of future disputes or costly litigation. Courts give significant weight to clear, notarized documents.

Are the rules different for same-sex couples?
Yes. Same-sex couples fall under Article 148 of the Family Code. In the 2025 Supreme Court decision Jennifer C. Josef vs. Evalyn G. Ursua (G.R. No. 267469), the Court recognized co-ownership based on proof of actual contributions and allowed partition of the property.

What happens to property we bought while living together if we later get married?
The co-ownership regime under the Family Code generally ends upon valid marriage. The property then becomes subject to your new marital property regime (absolute community of property by default, unless you execute a marriage settlement). Consult a lawyer about the implications before or right after marriage.

Where can I find more official information?
You can read the Family Code on reputable legal databases such as Chan Robles Virtual Law Library. Supreme Court decisions are available through the Supreme Court E-Library. For taxes and registration procedures, check the official BIR and Registry of Deeds websites or visit the local offices. Always verify the latest requirements, as procedures and fees can be updated.

Key Takeaways

Unmarried couples can own real property together as co-owners under Philippine law, with stronger protections available when both partners are Filipino and fall under Article 147 of the Family Code.
Clear documentation—especially a notarized agreement and having both qualified names on the title—is the most practical way to protect your investment and simplify future transactions or disputes.
Foreigners cannot own land; mixed couples should title land only in the Filipino partner’s name and explore condominium units or carefully structured agreements instead.
Plan ahead for separation and death. A will and a well-drafted co-ownership agreement help ensure your intentions are respected and reduce conflict for everyone involved, including any children.
The process of buying and registering property involves specific steps with the BIR and Registry of Deeds; timelines are typically one to three months for straightforward transfers but can vary.
Because every couple’s situation is unique (especially regarding prior marriages, contributions, or nationality), personalized advice from a licensed Philippine lawyer is the best next step before making a major purchase.
