Quick answer

Marriage and cohabitation do not create the same property rights in the Philippines.

For married couples, ownership depends primarily on the applicable property regime: a valid marriage settlement, absolute community of property, conjugal partnership of gains, or separation of property. Property acquired during marriage may be common even when the title, deed, loan, business registration, or receipt names only one spouse.

For unmarried partners, living together—even for many years—does not by itself create a marriage or an automatic right to half of everything. Articles 147 and 148 of the Family Code may create co-ownership, but the applicable rule depends on whether the partners could legally marry each other, whether the relationship was exclusive, and what each partner contributed. In 2025, the Supreme Court confirmed that Article 148 can also recognize co-ownership between same-sex partners who actually contributed to property acquired during their relationship.

The documents, acquisition dates, source of funds, legal status of each partner, and evidence of contribution usually determine the result. Do not sell, mortgage, transfer, waive, or surrender disputed property without obtaining advice on the specific documents.

First determine which property regime applies

Calling property “conjugal” does not establish its legal character. The starting point is the couple’s marriage date and marriage settlement, if any.

Under Articles 74 to 77 of the Family Code, spouses may choose their property regime in a written marriage settlement executed before the wedding. To affect third persons, the settlement must also be registered in the local civil registry where the marriage is recorded and in the proper property registries.

The usual rules are:

A marriage celebrated on or after August 3, 1988, without a valid marriage settlement is generally governed by absolute community of property.
A marriage celebrated before the Family Code took effect was ordinarily governed by the conjugal partnership of gains under the Civil Code, unless a valid settlement provided otherwise. Vested rights and older transactions may require separate analysis.
A valid marriage settlement may establish complete or partial separation of property, a conjugal partnership of gains, or another lawful arrangement.

A marriage settlement generally cannot be created or freely rewritten after the wedding. During marriage, separation of property ordinarily requires a judicial order, including a decree based on a sufficient statutory cause or a court-approved joint petition.

Absolute community of property

Under absolute community, the general rule is broad: property owned when the marriage begins and property acquired afterward form part of the community.

Important exclusions include:

Property acquired by inheritance, donation, or another gratuitous title, including its fruits and income, unless the donor, testator, or grantor expressly makes it community property;
Property for a spouse’s personal and exclusive use, although jewelry belongs to the community; and
Property acquired before the marriage by a spouse who has legitimate descendants from a former marriage, together with its fruits and income.

Property acquired during the marriage is presumed community property unless an exclusion is proved. Consequently, property bought before the wedding is not automatically separate under this regime.

Conjugal partnership of gains

Under a conjugal partnership of gains, each spouse generally retains property brought into the marriage. Property acquired during marriage by gratuitous title, or bought with demonstrably exclusive money, may also remain exclusive.

The partnership generally includes:

Earnings from either spouse’s work, profession, business, or industry;
Property acquired for value during the marriage using partnership funds;
Fruits and net income received during marriage from common property and from either spouse’s exclusive property; and
Certain acquisitions by chance.

Installment purchases, improvements built on exclusive land, exchanges, redemptions, mixed funding, and payments made partly before and partly during marriage require closer examination. Ownership may depend on when title vested, while the spouse or partnership that advanced funds may have a right to reimbursement upon liquidation.

Separation of property

Under a valid separation-of-property regime, each spouse generally owns, administers, enjoys, and disposes of their separate estate and keeps their earnings and the fruits of their property.

That does not eliminate family obligations. Spouses must contribute to family expenses in proportion to income or, when appropriate, the value of their separate properties. Their liability to creditors for proper family expenses may be solidary.

Does the name on the title control?

Not necessarily.

Under the Family Code, property acquired during marriage may be presumed community or conjugal even when registered only in one spouse’s name. A declaration in a deed that the buyer is “single,” or a tax declaration naming only one spouse, cannot by itself change property that the law treats as common.

But the person relying on the presumption must first prove that the property was actually acquired during the marriage. Registration and acquisition are not always the same event. Once acquisition during marriage is established, the party claiming that the property is exclusive generally bears the burden of overcoming the presumption with clear evidence. The Supreme Court applied these principles in Spouses Anastacio v. Heirs of Coloma.

A Torrens title is powerful evidence, but it does not make the acquisition date, source of funds, applicable marital regime, or a spouse’s legally required consent irrelevant.

Can one spouse sell or mortgage common property alone?

As a rule, no.

Administration and enjoyment of absolute-community or conjugal-partnership property belong to both spouses jointly. Disposition or encumbrance—such as a sale, mortgage, waiver, or similar transfer—requires the other spouse’s written consent or proper court authority.

For a disposition made after the Family Code took effect on August 3, 1988, the absence of required written consent generally makes the entire transaction void, not merely the non-consenting spouse’s supposed half. Awareness of negotiations, silence, or oral approval is not necessarily written consent.

The transaction is nevertheless treated by Articles 96 and 124 as a continuing offer that may become binding if the other spouse accepts it, or the court authorizes it, before the offer becomes ineffective or is withdrawn. In Alexander v. Spouses Escalona, the Supreme Court warned that an action challenging such a transaction should not simply be assumed to be imprescriptible.

A materially different rule governs an unauthorized disposition made before August 3, 1988. Under the former Civil Code provisions, the transaction was generally voidable, and the wife had ten years from the transaction to seek annulment. The date of the sale, mortgage, or encumbrance—not merely the marriage date—is therefore critical.

The Code also contains a five-year period for the wife to seek a judicial remedy from a contract implementing the husband’s decision in an administration disagreement under Articles 96 or 124. This is distinct from a sale or mortgage made without the written consent required for disposition.

Debts are not automatically shared

Marriage does not make every personal loan, fine, business loss, or other liability a common debt.

Community or partnership property may answer for obligations contracted:

By both spouses;
By one spouse with the other’s consent;
By the authorized administrator for the benefit of the community or partnership; or
By one spouse without consent, but only to the extent the family was actually benefited.

Personal debts, criminal fines, civil indemnities, support obligations to children outside the marriage, and gambling losses have special rules. Some amounts may be advanced from common property when the debtor-spouse lacks sufficient exclusive property, but later charged against that spouse’s share during liquidation. Liability therefore depends on the property regime, who signed, the purpose of the obligation, and proof of family benefit.

Physical separation does not end the property regime

Moving out, beginning another relationship, signing an informal separation agreement, or living apart for years does not by itself dissolve a marriage or terminate the absolute community or conjugal partnership.

While the marriage and property regime continue:

Common-property acquisitions and liabilities may continue to arise;
Written spousal consent may still be required for a sale or mortgage;
A spouse cannot simply assign themselves a particular house, vehicle, bank account, or business; and
Cohabitation with another person does not erase the lawful spouse’s existing rights.

When one spouse abandons the family, abuses administrative authority, or fails to meet family obligations, the other may be able to petition for receivership, sole administration, or judicial separation of property. Separation in fact for at least one year, when reconciliation is highly improbable, is one statutory ground for judicial separation of property. Spouses may also jointly seek court-approved dissolution of the community or partnership.

Legal separation, annulment, declaration of nullity, and judicial separation of property are different proceedings with different effects. A decree of legal separation dissolves and liquidates the property regime but does not sever the marriage bond.

Property rights of opposite-sex unmarried partners

When Article 147 applies

Article 147 generally applies when a man and woman:

Are legally capacitated to marry each other;
Live exclusively with each other as spouses; and
Are unmarried or are parties to a void marriage.

Under this special co-ownership:

Their wages and salaries are owned in equal shares;
Property acquired through their work or industry is co-owned;
Property acquired during the union is presumed obtained by their joint efforts and owned equally, unless contrary evidence is presented; and
Care and maintenance of the family and household expressly count as a contribution, even if one partner did not directly pay the purchase price.

During cohabitation, neither partner may dispose of or encumber even their share in property covered by Article 147 without the other’s consent. The Supreme Court explained this special regime in Valdes v. Regional Trial Court.

When Article 148 applies

Article 148 governs cohabitation outside Article 147—for example, when one or both partners have a legal impediment to marry because of a subsisting marriage, or the relationship does not meet Article 147’s exclusivity requirement.

Its protection is narrower:

Only property acquired through both partners’ actual joint contribution of money, property, or industry is co-owned;
Ownership is proportional to the proven contributions; and
Equal shares are presumed only after actual contribution by both partners is first established and the respective proportions cannot be proved.

Merely living in the property, having a long relationship, or showing that an asset was acquired during cohabitation does not automatically prove Article 148 co-ownership. Unlike Article 147, Article 148 does not expressly deem ordinary household care to be a joint contribution. Preserve direct evidence of payments, work, property supplied, or other qualifying industry.

If one partner is validly married to someone else, that partner’s share in the Article 148 co-ownership accrues to the absolute community or conjugal partnership of the valid marriage. Bad faith may also trigger statutory forfeiture rules.

Same-sex partners can establish Article 148 co-ownership

Philippine law still does not presently provide a domestic marriage regime for same-sex couples. That does not prevent them from owning property together.

In Josef v. Ursua, G.R. No. 267469, promulgated on February 5, 2025 and publicly released in 2026, the Supreme Court held that Article 148 is broad enough to recognize co-ownership arising from same-sex cohabitation. The claimant must still prove actual contribution.

A written acknowledgment by the titled partner, records of payments, or other competent evidence may establish the co-ownership. The ruling does not create an automatic 50–50 marital estate for every same-sex couple; it recognizes ownership based on actual joint contribution and the evidence in the case.

Cohabitation does not create a “common-law marriage”

The Philippines does not convert a couple into legally married spouses merely because they have lived together for five years, have children, use the same surname socially, or are known publicly as husband and wife.

Article 34 of the Family Code provides a marriage-license exemption for certain qualified opposite-sex couples who have cohabited for at least five years without a legal impediment. It does not eliminate the need for an actual marriage ceremony and compliance with the remaining legal requirements.

What happens after unmarried partners separate?

Once cohabitation ends, proven co-owned property may be divided by agreement or through judicial partition.

Under the Civil Code rules on co-ownership:

A co-owner may demand partition, subject to valid restrictions;
Partition may be made by agreement or judicial proceeding;
If an asset is essentially indivisible and the partners cannot agree that one will take it while paying the other, it may be sold and the proceeds distributed; and
The final accounting should address benefits received, necessary or useful expenses, reimbursements, income, and damage caused by negligence or fraud.

After an ordinary co-ownership arises, a co-owner may generally transfer an undivided interest, but that transfer affects the other co-owners only to the extent of the portion ultimately allotted to the seller. Article 147’s special consent restriction applies while the covered cohabitation continues.

A former partner cannot lawfully take the entire asset merely because they possess it or hold the owner’s duplicate title. Conversely, paying some expenses does not automatically prove ownership of half the asset; the payment’s purpose and the parties’ agreement still matter.

Inheritance rights are different from ownership rights

Property must first be classified and, when necessary, liquidated before inheritance shares can be determined.

A surviving legal spouse may have:

Their own share from the liquidation of community or conjugal property; and
A separate hereditary share in the deceased spouse’s estate.

The surviving spouse is a compulsory heir, although the precise share depends on the presence of children, parents, other heirs, a valid will, debts, and the applicable succession rules.

An unmarried partner does not become a compulsory or intestate heir merely because of cohabitation. The partner may first recover a proven ownership share under Article 147, Article 148, a title, or an enforceable agreement. Anything belonging solely to the deceased passes under a valid will or the rules of intestate succession—not automatically to the surviving partner.

A will may benefit an unmarried partner within the portion the testator may legally dispose of, but compulsory heirs and statutory disqualifications must be respected. Donations and insurance-beneficiary designations can also be invalid in certain adulterous or prohibited relationships. Estate planning should therefore be prepared with legal advice rather than informal promises.

After a married spouse dies, the Family Code requires liquidation in the estate proceeding or, if none is filed, judicial or extrajudicial liquidation by the surviving spouse. Article 103 sets a one-year period for absolute-community property; Article 130 sets six months for a conjugal partnership of gains. Delay can invalidate or limit later dispositions and can affect the property regime of a subsequent marriage, so estate settlement should begin immediately.

Foreign spouses and partners

Marriage to a Filipino does not itself authorize a foreign national to buy Philippine land.

Article XII, Section 7 of the 1987 Constitution generally prohibits transfer of private land to persons not qualified to acquire land, except in cases of hereditary succession. The constitutional restriction concerns land; buildings and other improvements can present different ownership questions, as the Supreme Court explained in Borromeo v. Descallar.

Do not place land in a Filipino spouse’s or partner’s name as a nominee while privately treating the foreigner as the real landowner. Such an arrangement can be unenforceable and expose the parties to serious legal consequences. Condominium units, leases, inherited land, former natural-born Filipinos, and ownership of improvements have separate rules requiring transaction-specific advice.

Practical steps when property is disputed

1. Identify the controlling relationship and dates

Record:

The marriage and separation dates, if any;
Whether either partner had another subsisting marriage;
The date each asset was contracted, paid for, delivered, titled, or registered;
Whether the relationship was exclusive;
The date cohabitation began and ended; and
The citizenship of each person.

2. Obtain the governing documents

Secure certified or original copies of:

The PSA marriage certificate and any prior marriage or court decree;
The marriage settlement and proof of registration;
Deeds of sale, donation, assignment, waiver, and mortgage;
Loan and installment contracts;
Transfer, original, or condominium certificates of title;
Tax declarations and real-property tax records;
Vehicle registrations;
Business registrations, corporate records, and partnership agreements;
Bank, investment, insurance, and retirement records; and
Wills, estate papers, or settlement documents.

For registered land, request a current Certified True Copy from the Registry of Deeds or through the LRA eSerbisyo portal. Check the registered owner, civil status shown, mortgages, adverse claims, notices of lis pendens, and other annotations.

3. Preserve evidence of payment and contribution

Keep:

Bank statements and deposit slips;
Payroll records and remittance receipts;
Loan amortization and down-payment records;
E-wallet histories;
Construction and renovation invoices;
Receipts for materials, taxes, insurance, and major repairs;
Written acknowledgments of ownership or contribution;
Emails, messages, and letters discussing shares or repayment;
Records of work performed for a family business or the property; and
Photographs and an inventory of movable property.

Keep original files and metadata where possible. Make secure backups. Do not enter another person’s account, impersonate them, secretly alter records, or obtain evidence unlawfully.

4. Prevent an unauthorized transfer lawfully

If a sale, mortgage, foreclosure, or title transfer is imminent, consult counsel immediately. A demand letter alone may not stop registration or protect against third parties.

Depending on the facts, counsel may consider an action for declaration of nullity, reconveyance, partition, accounting, injunction, receivership, or another appropriate remedy, together with a legally supportable title annotation. The Registry of Deeds registers proper instruments and court orders; it does not finally decide a disputed ownership claim.

5. Use a properly documented settlement when agreement is possible

A settlement should identify:

Every asset and debt;
The legal basis and percentage of each share;
Reimbursements and accounting adjustments;
Who will possess the property pending transfer;
Whether one party will buy out the other;
Taxes, fees, loan balances, and transfer expenses;
Deadlines and default remedies; and
Required BIR, local-government, lender, and Registry of Deeds compliance.

A private agreement affecting land generally requires the correct public instrument, tax clearances, Certificate Authorizing Registration when applicable, and registration. The LRA’s official requirements should be checked for the particular transaction.

Common and costly mistakes

Assuming every married couple owns everything 50–50 immediately;
Assuming property bought before marriage must remain separate under absolute community;
Believing the titled spouse or partner is automatically the sole beneficial owner;
Treating physical separation as the end of the marital property regime;
Assuming a live-in partner always receives half after breakup;
Relying on an oral promise that “this is also yours” without preserving proof;
Treating mortgage payments as conclusive proof of ownership without showing why they were paid;
Signing a quitclaim, waiver, extrajudicial settlement, deed, or special power of attorney without an independent explanation;
Allowing an unauthorized sale to proceed because “the buyer already knows we are married”;
Using a Filipino spouse or partner as a land nominee for a foreigner; and
Waiting until the title has been transferred, the property foreclosed, evidence deleted, or the other party dies.

When legal help is urgent

Seek immediate help if:

A deed or signature may have been forged;
A sale, mortgage, foreclosure, auction, or transfer is scheduled or already being registered;
Someone is removing vehicles, equipment, inventory, documents, or money;
A spouse or partner is being forced to sign a waiver or deed;
A bank account or business is being drained or concealed;
One party has died and estate property is being sold without liquidation or settlement;
A foreign national’s land interest is involved;
There are multiple marriages, a void marriage, or an unresolved foreign divorce;
The dispute involves violence, stalking, threats, forced eviction, destruction of property, or financial control; or
A possible filing period is running.

Economic abuse under Republic Act No. 9262 can include depriving a woman of the use and enjoyment of community, conjugal, or commonly owned property; destroying household property; or controlling her money or property to make her financially dependent. Court protection orders may grant temporary possession of a residence, vehicle, or essential personal effects regardless of disputed ownership. A woman facing danger may approach law enforcement, the barangay VAW Desk, or the courts; the Philippine Commission on Women maintains official referral information.

Frequently asked questions

If my name is not on the title, do I have no rights?

Not necessarily. A spouse may rely on the applicable marital-property presumption after proving acquisition during marriage. An unmarried partner must establish co-ownership through Article 147, Article 148, a contract, title evidence, or another lawful basis.

Can my spouse sell a conjugal house without my signature?

A post-August 3, 1988 disposition of community or conjugal property without the other spouse’s written consent or court authority is generally void. Mere awareness is not written consent. Act promptly because the proper remedy and timing depend on the transaction.

Does paying the mortgage make me a co-owner?

It is important evidence, but not always conclusive. The court may consider who acquired title, the property regime, the reason for the payments, any reimbursement arrangement, and whether both partners made qualifying contributions.

Does a homemaker have a share in property bought by a live-in partner?

Under Article 147, care and maintenance of the family and household expressly count as joint contribution. Under Article 148, actual contribution by both partners must be proved; the same automatic homemaking rule is not stated.

Can a married person and a new live-in partner own property together?

Possibly, but Article 148 generally applies and requires proof of actual joint contribution. The married partner’s share may accrue to the property regime of the valid marriage. The legal spouse’s rights cannot be displaced simply by putting the title in the new partner’s name.

Do same-sex partners have property rights?

Yes. They may own property through title, contract, ordinary co-ownership, and—under Josef v. Ursua—Article 148 when actual joint contribution is proved. There is no automatic marital estate solely because of the relationship.

Can an unmarried partner inherit without a will?

Not merely by being a partner. The survivor may recover their own proven co-ownership share, but the deceased’s separate property passes to legal heirs under intestate succession unless a valid will provides otherwise.

Can one co-owner force a sale?

A co-owner ordinarily may demand partition. If the property cannot be physically divided and no buyout is agreed, a court may order its sale and distribution of the proceeds. Article 147 restricts unilateral disposition while the qualifying cohabitation continues.
