Quick answer

Property rights depend first on whether the couple is validly married, what property regime governs the marriage, when and how the property was acquired, and whether the parties can prove their contributions.

For most marriages celebrated on or after 3 August 1988 without a valid prenuptial agreement, absolute community of property applies. Many assets owned before the wedding and acquired afterward become community property, subject to statutory exclusions.

For unmarried partners, there is no automatic “conjugal property” simply because they have lived together for many years:

Couples legally capable of marrying each other who live exclusively as spouses generally fall under Article 147 of the Family Code. Property acquired during cohabitation is presumed jointly acquired in equal shares, and caring for the family and household counts as a contribution.
Other relationships generally fall under Article 148. This includes relationships where a party is married to someone else and, following the Supreme Court’s ruling in Josef v. Ursua, same-sex cohabitation. Only property acquired through proven actual joint contributions is co-owned, in proportion to those contributions.

A name on a title, deed, registration certificate, loan, or bank account is important evidence, but it does not always settle beneficial ownership. The controlling regime, source of funds, acquisition date, written agreements, and other evidence may lead to a different result.

Start by identifying the governing property regime

Validly married couples

Under Articles 74 to 77 of the Family Code, property relations are governed in this order:

A valid marriage settlement or prenuptial agreement;
The Family Code; and
Applicable local custom.

A marriage settlement must be written, signed, and executed before the wedding. To affect third parties, it must also be registered in the local civil registry where the marriage is recorded and in the appropriate property registries. A private agreement made after the wedding ordinarily cannot retroactively replace the existing regime; changing the regime during marriage generally requires a court proceeding authorized by law.

The principal regimes are:

Regime	Basic rule
Absolute community of property	Generally includes property owned at the time of marriage and property acquired afterward, except statutory exclusions
Conjugal partnership of gains	Each spouse generally retains separate capital, while earnings, income, fruits, and acquisitions from work or common funds become conjugal
Complete separation of property	Each spouse generally owns and administers separate property and earnings, while both remain responsible for family expenses under the law

For marriages celebrated from 3 August 1988 onward, absolute community is the default when there is no valid marriage settlement. Marriages celebrated before that date were ordinarily governed by the Civil Code’s default conjugal partnership, although the documents, transaction dates, vested rights, and later Family Code provisions must be examined.

Muslim marriages covered by the Code of Muslim Personal Laws follow different rules. In the absence of a contrary stipulation, that Code generally provides for complete separation of property.

Unmarried or void-marriage relationships

The ordinary marital regimes do not automatically govern unmarried partners or parties to a void marriage. Their property rights are instead determined principally under Articles 147 and 148 of the Family Code and the Civil Code rules on co-ownership.

A ceremony or marriage certificate does not necessarily establish an absolute community or conjugal partnership if the marriage is later found void. The precise consequences may also depend on legal capacity, exclusivity, good faith, existing marriages, and the ground for nullity.

Absolute community of property

Under absolute community, the starting rule is broad: property owned when the marriage begins and property acquired afterward belong to the community unless a marriage settlement or the Family Code excludes them.

Important exclusions under Article 92 include:

Property acquired during marriage by inheritance, donation, or another gratuitous title, including its fruits and income, unless the donor or testator expressly made it community property;
Property for the personal and exclusive use of one spouse, although jewelry is included in the community; and
Property owned before marriage by a spouse who has legitimate descendants from a former marriage, including the property’s fruits and income.

Property acquired during marriage is presumed community property unless the exclusion is proved. Because the presumption is rebuttable, documents showing inheritance, donation, premarital ownership, or another exclusive source should be preserved.

Conjugal partnership of gains

Under this regime, property brought into the marriage generally remains exclusive. The common fund ordinarily includes:

Earnings from either spouse’s work, profession, business, or industry;
Property acquired during marriage using conjugal funds;
Fruits and income received during marriage from conjugal property;
Net fruits from each spouse’s exclusive property; and
Certain acquisitions by chance or occupation.

Property acquired during marriage is presumed conjugal even if the deed or title names only one spouse. The person claiming that it is exclusive must prove the applicable exception.

Inheritance and donations to one spouse generally remain that spouse’s exclusive property. Property purchased entirely with traceable exclusive funds may also remain exclusive. Installment purchases, exchanges, renovations, and transactions using mixed exclusive and conjugal funds require closer analysis, including when ownership vested and whether reimbursement is due.

Complete separation of property

When a valid marriage settlement establishes complete separation:

Each spouse owns, possesses, administers, and disposes of separate property;
Each keeps earnings from work, profession, business, or industry and the fruits of separate property; and
Both bear family expenses in proportion to income or, when necessary, the value of their separate properties.

Their liability to creditors for family expenses may nevertheless be solidary. “Separation of property” therefore does not mean that one spouse can disregard lawful family obligations.

During marriage, separation of property ordinarily cannot be created by a simple private agreement. Articles 134 to 140 allow judicial separation for specified causes, including abandonment, abuse of administration, certain judgments affecting a spouse, or factual separation for at least one year when reconciliation is highly improbable. The spouses may also jointly file a verified petition for voluntary dissolution of the community or conjugal partnership, with creditors identified and protected.

Whose name appears on the title?

Registration is powerful evidence, but it must be read together with the governing property regime.

For married couples:

Property acquired during marriage may be community or conjugal even if registered in only one spouse’s name.
A deed describing a buyer as “single” does not necessarily defeat the other spouse’s rights if the buyer was actually married.
Property registered in both names is not automatically divided according to assumptions made without examining the marriage settlement, acquisition documents, source of funds, and applicable law.
Corporate property belongs to the corporation. A spouse may own shares in the corporation without personally owning each corporate asset.

For unmarried partners, sole registration may be challenged by proof of co-ownership, but the required proof differs sharply between Articles 147 and 148.

Article 147: partners free to marry each other

Article 147 generally applies when a man and a woman:

Have no legal impediment to marrying each other;
Live exclusively with each other as spouses; and
Are unmarried or living under 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 cohabitation is presumed obtained through joint effort and owned equally, unless the contrary is proved.
A partner who did not directly pay may still be deemed to have contributed through care and maintenance of the family and household.

The presumption applies to property acquired during the qualifying cohabitation. A partner should still prove the acquisition date and the existence and character of the relationship.

While cohabitation continues, neither partner may dispose of or encumber even their share in covered common property without the other’s consent. Special forfeiture rules may apply when a void marriage involves good faith and bad faith.

In Valdes v. Regional Trial Court, G.R. No. 122749, the Supreme Court confirmed that property relations in a void marriage are governed by Article 147 or 148, as the facts require, rather than automatically by the liquidation rules for a valid marital community.

Article 148: actual contribution must be proved

Article 148 governs cohabitations outside Article 147. Common examples include:

A partner remains validly married to another person;
The relationship is bigamous, adulterous, or otherwise affected by a legal impediment;
The relationship does not satisfy Article 147’s exclusivity requirements; and
Same-sex partners live together and acquire property.

Under Article 148:

Only property acquired through the parties’ actual joint contribution of money, property, or industry is co-owned.
Ownership is proportional to proven contributions.
Equal shares may be presumed only after actual joint contribution has been established and no reliable evidence shows different proportions.
The same rule applies to joint deposits and evidences of credit.

Household care does not receive the same automatic treatment that Article 147 expressly provides. A person relying on Article 148 should preserve direct evidence connecting their money, property, work, or industry to the acquisition or improvement of the particular asset.

In Agapay v. Palang, G.R. No. 116668, the Supreme Court emphasized that cohabitation alone does not establish co-ownership under Article 148; actual contribution must be proved.

Article 148 also contains important forfeiture rules. If a party is validly married to someone else, that party’s share in the co-ownership accrues to the absolute community or conjugal partnership of the valid marriage. Other forfeitures may depend on bad faith and the existence of common children or descendants. These consequences are fact-sensitive and should not be implemented informally.

Same-sex partners can establish co-ownership

In Josef v. Ursua, G.R. No. 267469, 5 February 2025, the Supreme Court applied Article 148 to same-sex cohabitation. The Court recognized co-ownership where a signed acknowledgment established that one partner had paid approximately half of the acquisition and renovation expenses, despite the title being registered solely in the other partner’s name.

The ruling does not create an automatic 50–50 regime for every same-sex relationship. A claimant must still establish an actual contribution to the particular property. Once joint contribution is proved, the evidence determines the shares; equality is presumed only when no sufficient evidence establishes a different proportion.

The ruling concerns property co-ownership. It does not by itself create a marriage, civil union, or the full inheritance and other legal rights granted to spouses.

Debts and loans

Married couples

A debt in one spouse’s name is not automatically either personal or chargeable to the community. Relevant questions include:

Did both spouses contract or consent to it?
Was it incurred by the authorized administrator?
Did the family or common property actually benefit?
Was it a premarital debt?
Does it arise from a crime, quasi-delict, fine, or personal obligation?
Was common property pledged or mortgaged with the required consent?

Under Articles 94 and 121, debts contracted by one spouse without the other’s consent may generally be charged to the community or conjugal partnership only to the extent that the family benefited. Other personal obligations may be collectible from marital assets only under specific statutory conditions, priorities, and reimbursement rules.

Unmarried partners

There is no general marital community responsible for every debt. Liability normally follows the loan, guaranty, contract, agency, co-ownership rules, and proof of who received the benefit. A person who signed as borrower, co-maker, guarantor, or mortgagor should not assume that separation from the partner ends liability to the creditor.

Selling, mortgaging, or donating property

Administration and enjoyment of absolute-community and conjugal-partnership property belong to both spouses jointly.

A disposition or encumbrance ordinarily requires:

The other spouse’s written consent; or
Court authority when the required consent cannot be obtained in circumstances recognized by law.

Without either, Articles 96 and 124 describe the transaction as void but treat it as a continuing offer that may become binding if the other spouse accepts or the court authorizes it before withdrawal or other termination of the offer.

Mere knowledge, silence, participation in negotiations, or oral approval should not be treated as a substitute for legally required written consent. In Alexander v. Escalona, G.R. No. 256141, the Supreme Court clarified that transactions made after the Family Code took effect are governed by Articles 96 or 124, subject to vested rights, and that the entire unauthorized disposition may be void.

Important exceptions include:

A spouse may ordinarily dispose of genuinely exclusive property without the other spouse’s consent.
A family home may be subject to additional consent requirements under Article 158.
Moderate donations for charity or occasions of family rejoicing or distress are treated differently.
Transactions completed before 3 August 1988 may be governed by former Civil Code rules and different remedies or periods.

If an unauthorized deed, mortgage, waiver, quitclaim, or special power of attorney has already been signed, obtain legal advice immediately. Do not assume that calling a transaction “void” means a challenge can safely be postponed indefinitely; the remedy and applicable period depend on the transaction date and subsequent events.

Separation does not automatically divide the property

Living apart—even for many years—does not by itself terminate an absolute community or conjugal partnership. Until the regime is lawfully terminated, later acquisitions and transactions may still be affected by it.

A regime may terminate through:

Death of a spouse;
A decree of legal separation;
Annulment or declaration of nullity;
Judicial separation of property; or
Other circumstances expressly recognized by law.

Legal separation allows spouses to live separately but does not end the marriage bond. It dissolves and liquidates the property regime, and statutory forfeiture of net profits may apply to the offending spouse. A petition for legal separation must generally be filed within five years from the occurrence of the cause.

When a spouse dies, community property should be liquidated in the estate proceeding. If no judicial estate proceeding is filed, the surviving spouse must undertake judicial or extrajudicial liquidation within six months from death. After that period, a disposition or encumbrance of unliquidated community property is void under Article 103.

The Family Code also gives a wife a five-year period from the contract implementing the husband’s decision to seek a court remedy in the management-disagreement situation described in Articles 96 and 124. That rule is different from a disposition made entirely without the written consent required by those articles.

What happens when a partner dies?

For a valid marriage, liquidation comes before inheritance:

Exclusive property is identified.
Community or conjugal debts and reimbursements are settled.
The surviving spouse receives the share belonging to them under the property regime.
The deceased spouse’s exclusive property and share in the net common property form part of the estate.
The surviving spouse may then inherit as a compulsory or intestate heir under the Civil Code.

An unmarried partner does not automatically inherit as a surviving spouse. The partner must first establish and separate any property already belonging to them as owner or co-owner. The deceased partner’s remaining share passes to heirs under succession law.

A will may protect an unmarried partner, but only within the disposable portion of the estate and subject to compulsory heirs, formal requirements, incapacity or disqualification rules, and other legal restrictions. Joint ownership documents, beneficiary designations, and estate planning should be reviewed together rather than used as substitutes for one another.

Evidence worth preserving

Property cases are frequently decided by records rather than by who gives the more compelling personal account. Preserve:

PSA marriage certificates and any annotation concerning nullity, annulment, or legal separation;
The original marriage settlement and proof of registration;
Certified copies of titles, condominium certificates, tax declarations, deeds, contracts to sell, and Registry of Deeds annotations;
Vehicle registrations, share certificates, business records, insurance policies, and records of valuable personal property;
Loan applications, mortgage documents, statements of account, amortization schedules, and proof of payments;
Bank statements, remittance records, payroll records, deposit slips, transfer confirmations, and receipts;
Documents showing the source of exclusive funds, including inheritance papers, deeds of donation, premarital bank records, and proceeds from the sale of exclusive property;
Receipts, contracts, photographs, permits, and messages concerning construction or renovations;
Written acknowledgments of ownership, contribution, debt, reimbursement, or an agreement to sell and divide proceeds;
Evidence establishing when cohabitation began and ended and, for Article 147, household and caregiving contributions;
Records showing how borrowed money benefited—or did not benefit—the family;
Complete message exports and emails with dates and identifying information, not only cropped screenshots; and
An inventory showing present location, condition, estimated value, income, occupants, and known encumbrances for every disputed asset.

Keep originals secure and make read-only copies. Do not alter messages, fabricate receipts, backdate agreements, or access accounts without authority.

Practical steps when ownership is disputed

Fix the timeline. Record the wedding or start of cohabitation, acquisition dates, payment dates, separation date, and every sale, mortgage, transfer, inheritance, or donation.
Identify the correct regime. Check the marriage date, validity of the marriage, marriage settlement, legal impediments, exclusivity of cohabitation, nationality, and any prior or later marriage.
Obtain official records. Secure certified title and encumbrance records from the Registry of Deeds, tax declarations, civil-registry documents, and complete loan records.
Trace each asset separately. A house, business shares, vehicle, joint account, inherited land, and digital asset may not all have the same legal character.
Send a careful written demand if appropriate. Identify the claimed share, requested accounting, documents needed, and proposed resolution. Avoid admissions or accusations that have not been verified.
Consider a documented settlement. Possible solutions include sale and division of net proceeds, physical partition, a buyout based on independent valuation, reimbursement, or continued co-ownership under a written management agreement. Proper deeds, taxes, lender consent, notarization, and registration may still be required.
Protect the property through lawful measures. If a sale, mortgage, or transfer is imminent, a lawyer can assess an adverse claim, notice of lis pendens, injunction, receivership, or another provisional remedy. These are technical remedies with consequences if improperly used.
File the correct case if settlement fails. A co-owner may seek partition and accounting under Rule 69 of the Rules of Court. The complaint must identify the nature and extent of the claimant’s title, adequately describe the property, and include all interested persons.

For an ordinary action involving title to or an interest in real property, trial-court jurisdiction generally depends on the property’s assessed value: under Republic Act No. 11576, a first-level court generally has jurisdiction when the assessed value does not exceed ₱400,000, while the Regional Trial Court generally has jurisdiction when it exceeds that amount. Cases tied to nullity, annulment, legal separation, or another matter within the Family Courts Act may follow different jurisdictional rules. Filing in the wrong court can waste substantial time, so the precise cause of action should be classified before filing.

Planning ahead

Before marriage

Future spouses should discuss:

The preferred property regime;
Existing real estate, businesses, investments, debts, and children from earlier relationships;
Treatment of future earnings and inherited property;
Management of businesses and major assets;
Responsibility for family expenses; and
Registration of the marriage settlement.

Independent legal advice for each future spouse is especially important where there are substantial assets, a family business, foreign property, prior families, or unequal debts.

For unmarried partners

A properly drafted co-ownership agreement can record:

Which assets are separate or joint;
Each person’s initial and continuing contributions;
Exact ownership percentages;
Responsibility for loans, taxes, maintenance, and improvements;
Use of the property during the relationship;
Records and accounting obligations;
Buyout, valuation, sale, and partition procedures; and
What happens upon separation, incapacity, or death.

Whenever possible, both partners should be named in acquisition documents with their intended shares. Agreements cannot override constitutional land-ownership restrictions, creditor rights, compulsory-heir rules, statutory forfeitures, or public policy.

Foreign nationality requires particular care. The Constitution generally prohibits non-Filipinos from acquiring Philippine private land except in limited cases such as hereditary succession. Putting land in a Filipino partner’s name as a device to evade that restriction can create serious ownership and recovery problems.

Common mistakes

Assuming all property becomes 50–50 upon marriage;
Assuming a long live-in relationship creates a marriage or automatic conjugal property;
Treating the name on the title as the only relevant fact;
Claiming equal ownership under Article 148 without first proving actual contribution;
Paying in cash without receipts or a written acknowledgment;
Treating household work as automatically sufficient under Article 148;
Signing a quitclaim, waiver, deed, mortgage, settlement, or special power of attorney without independent advice;
Backdating a “prenup” after the wedding;
Selling the whole co-owned property when only an undivided share is owned;
Confusing ownership of corporate shares with ownership of corporate assets;
Assuming factual separation ended the marital property regime;
Ignoring the rights of a valid spouse, children, creditors, lenders, or compulsory heirs; and
Waiting until the property has been transferred, foreclosed, extensively altered, or included in a deceased partner’s estate.

When legal help is urgent

Consult a Philippine family or property lawyer promptly if:

A sale, mortgage, foreclosure, transfer, or withdrawal is imminent;
Your signature was forged or a document falsely states that you consented;
A partner is hiding assets, destroying records, or transferring property to relatives or companies;
A spouse or partner has died and the estate is being settled without recognizing your claim;
The property is the family home or the residence of minor children;
One party is a foreign national;
The dispute involves multiple marriages, a void marriage, inherited property, substantial business assets, or several creditors;
You are being pressured to sign a waiver or leave the property immediately; or
There are threats, violence, stalking, coercion, or deliberate economic control.

For women experiencing violence or qualifying economic abuse by a husband, former husband, dating or sexual partner, or a person with whom they have a common child, Republic Act No. 9262 provides barangay, temporary, and permanent protection orders. A protection order can include safety measures, temporary use of essential property, support when legally due, and removal of the respondent from a residence in appropriate circumstances. Contact the Barangay VAW Desk, the PNP Women and Children Protection Desk, emergency services, or the Philippine Commission on Women’s official helpline directory if immediate protection is needed.

Frequently asked questions

Is a house automatically mine because the title is only in my name?

No. For spouses, the property regime, acquisition date, and source of funds may create community or conjugal ownership despite sole registration. For unmarried partners, sole registration may still be challenged by sufficient proof of co-ownership.

I paid all the installments. Does that make me the sole owner?

Not necessarily. Under a marital regime, earnings and funds used may themselves be community or conjugal. Under Article 147, equal ownership and household contribution presumptions may apply. Under Article 148, proof that only you actually funded the acquisition may establish a larger or exclusive share, but all evidence must be considered.

We have lived apart for years. Is property acquired afterward still common?

Possibly. Factual separation alone does not terminate an absolute community or conjugal partnership. A judicial decree, death, annulment, declaration of nullity, or judicial separation of property may be necessary.

Can my spouse sell community or conjugal property without my signature?

Ordinarily no. Written consent or court authority is generally required. Exclusive property is treated differently, and the family home may carry additional consent requirements.

Can a same-sex partner claim a share in property?

Yes, when actual contribution is proved. Under Josef v. Ursua, Article 148 can govern same-sex cohabitation. There is no automatic marital or 50–50 regime.

Does having a common child make the child a co-owner?

Not by itself. A child’s rights to support, inheritance, presumptive legitime, or forfeited shares arise under separate rules. The child does not automatically own every property acquired by the parents or partners.

Does infidelity automatically forfeit a spouse’s half?

No. Forfeiture depends on specific statutory provisions, the type of proceeding, a final decree, good or bad faith, and the character of the property or net profits. It should not be assumed from infidelity alone.

Can unmarried partners agree in writing that property will be divided equally?

They may document an intended co-ownership and their contributions, subject to formalities and applicable law. The agreement cannot create a marriage or defeat constitutional restrictions, creditor rights, compulsory heirs, or mandatory forfeiture rules.
