Quick answer

Marriage does not automatically make every asset “50–50,” and living together does not automatically give an unmarried partner half of everything.

For married couples, ownership depends mainly on:

the date of the marriage;
any valid marriage settlement signed before the wedding;
when and how the property was acquired;
whether it was inherited, donated, or bought with exclusive funds; and
whether the marriage is valid, voidable, or void.

Without a valid marriage settlement, the usual default is:

Absolute community of property for marriages celebrated on or after August 3, 1988; or
Conjugal partnership of gains for many marriages celebrated before that date, subject to vested rights and the applicable Civil Code rules.

For unmarried partners and parties to a void marriage, the rules are different. Article 147 of the Family Code may create an equal co-ownership when the partners were legally free to marry each other and lived exclusively as spouses. Article 148 generally requires proof of actual contribution when the relationship does not meet those conditions, such as when one partner was already married.

A title, receipt, loan, or bank account bearing only one person’s name is important evidence, but it does not always settle the ownership question. The complete documents and circumstances must be examined.

First identify the relationship and governing property regime

Before asking who owns a house, vehicle, business, savings account, or investment, establish these facts:

Was there a valid marriage?
When was it celebrated?
Was a marriage settlement executed before the wedding?
Was that settlement properly registered?
When was the disputed property acquired?
What funds, work, or other contributions paid for it?
Was either partner legally married to someone else during the acquisition?
Has the marriage or cohabitation ended, and if so, how?

These questions matter because Philippine law treats valid marriages, void marriages, and informal unions differently.

The principal rules appear in the Family Code of the Philippines. Muslim marriages and divorces covered by the Code of Muslim Personal Laws follow a distinct framework, including complete separation of property as the statutory default unless the spouses validly agree otherwise. See Presidential Decree No. 1083.

Property rights in a valid marriage

Marriage settlements come first

Future spouses may choose absolute community, conjugal partnership of gains, complete separation of property, or another lawful arrangement in a marriage settlement. It must generally be:

in writing;
signed before the marriage; and
registered, together with the marriage certificate, in the proper civil registry and registries of property to affect third persons.

A private agreement signed only after the wedding ordinarily cannot replace the existing regime at will. Judicial approval may be required for a separation of property during marriage.

Absolute community of property

Under absolute community, the community generally consists of property owned by the spouses when the marriage begins and property acquired afterward.

Important exclusions under Article 92 include:

property acquired during marriage by inheritance or donation to one spouse, 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, except jewelry; and
property owned before the marriage by a spouse who has legitimate descendants from a former marriage, including its fruits and income.

Property acquired during the marriage is presumed to belong to the community unless an exclusion is proved. Registration in only one spouse’s name does not necessarily defeat that presumption.

Conjugal partnership of gains

Under a conjugal partnership, each spouse generally keeps ownership of exclusive property brought into the marriage. The partnership ordinarily includes the fruits and income of the spouses’ separate property and property acquired through either spouse’s labor, profession, business, or industry during the marriage.

Exclusive property generally includes:

property brought into the marriage;
property acquired during marriage by inheritance or donation to one spouse;
property acquired by redemption, barter, or exchange using exclusive property; and
property bought with exclusive money, provided the exclusive source can be proved.

The party claiming that an asset acquired during marriage is exclusive normally needs strong documentary proof. The Supreme Court has repeatedly held that once acquisition during the marriage is established, the statutory presumption may apply even when the title names only one spouse. See Nayve-Pua v. Union Bank and Metrobank v. Chan.

Debts are not automatically shared

Being married does not make every personal debt chargeable against community or conjugal property.

Liability depends on matters such as:

whether both spouses agreed to the obligation;
whether the authorized administrator incurred it;
whether it benefited the family or common property;
whether it concerns taxes, preservation, support, or another charge recognized by law; and
whether it arose from a spouse’s crime, quasi-delict, gambling, or purely personal undertaking.

A lender’s contract with only one spouse should therefore be examined together with the purpose of the loan and the applicable property regime.

One spouse usually cannot sell or mortgage common property alone

Administration and enjoyment of absolute-community or conjugal property belong to both spouses jointly. A sale, mortgage, or other encumbrance generally requires the other spouse’s written consent or court authority.

Under Articles 96 and 124, a disposition or encumbrance made without the required consent or authority is void. The transaction may operate only as a continuing offer that can become binding if the other spouse accepts, or the court authorizes it, before withdrawal.

This rule concerns common property. If the asset is genuinely exclusive property, the owner-spouse generally administers and disposes of it independently, subject to special rules such as those protecting a family home.

Separation in fact does not by itself divide the property

Moving out, living separately, or starting another relationship does not automatically dissolve the absolute community or conjugal partnership.

The regime ordinarily ends upon:

death of either spouse;
a decree of legal separation;
annulment or declaration of nullity; or
judicial separation of property.

Until proper liquidation, spouses should not assume that they already own specific physical halves of each common asset. Liquidation first accounts for debts, reimbursements, exclusive property, common assets, and the spouses’ eventual shares.

Property rights of unmarried partners

There is no single “common-law spouse” rule granting every live-in partner half of the other partner’s property. The Family Code distinguishes two situations.

Article 147: partners legally free to marry each other

Article 147 may apply when a man and a woman:

were legally capacitated to marry each other;
lived exclusively with each other as spouses; and
had no marriage or had a void marriage.

Under this rule:

their wages and salaries are owned in equal shares;
property acquired through their work or industry is governed by co-ownership;
property acquired during cohabitation is presumed, unless disproved, to have resulted from their joint efforts and to be owned equally; and
homemaking, childcare, and maintenance of the family and household count as contribution even without direct financial payment.

Neither partner may dispose of or encumber their share in property acquired and owned in common during the cohabitation without the other’s consent until the cohabitation ends.

These presumptions are rebuttable. Evidence showing that an asset was acquired before cohabitation, inherited, donated exclusively, or bought solely with traceable separate funds may change the result. The Supreme Court also emphasizes that the claimant must first establish the facts bringing the relationship and acquisition within Article 147. See Ocampo v. Ocampo and Nayve-Pua v. Union Bank.

Article 148: an impediment to marriage or another nonqualifying union

Article 148 generally governs cohabitation not covered by Article 147, including relationships in which one or both partners were validly married to another person.

Only property acquired through the partners’ actual joint contribution of money, property, or industry is co-owned. Their shares are proportional to their contributions. If actual joint contribution is established but its respective extent is not proved, the contributions and shares are presumed equal.

This distinction is critical: Article 148 does not generally treat household care alone as the same statutory contribution recognized under Article 147. A claimant should preserve concrete proof of money, property, or industry contributed to acquiring the particular asset.

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. Forfeiture rules may also apply where bad faith is established.

The Supreme Court has required proof connecting the contribution to the disputed property, not merely proof that the couple lived together. See Saguid v. Court of Appeals, Villanueva v. Court of Appeals, and Tan-Andal v. Andal.

Dating or sharing a home is not necessarily enough

Articles 147 and 148 concern cohabitation as spouses, not every dating relationship, house-sharing arrangement, or joint purchase.

Partners outside those provisions may still have rights based on:

the title or registration;
a written purchase or co-ownership agreement;
a partnership or business agreement;
proof of payment;
trust, reimbursement, or other applicable Civil Code principles; or
the ordinary rules on co-ownership.

The Family Code’s text defines marriage and Articles 147 and 148 in terms of a man and a woman. Partners whose relationship does not fall within those provisions should use clear contracts, accurate titles, estate planning, and documented contributions rather than assume that marital property rules apply.

What happens to jointly owned property after separation?

When unmarried co-owners separate, either may generally seek partition under the Civil Code. If the property can be divided without making it unusable, it may be physically divided. If it is indivisible and the co-owners cannot agree that one will take it and pay the other, a court may order its sale and distribution of the proceeds according to the proven shares.

A negotiated settlement may address:

the inventory and agreed values;
ownership percentages;
responsibility for loans, taxes, and repairs;
occupancy pending transfer or sale;
buyout terms and payment dates;
sale procedure and choice of broker;
treatment of rental income; and
execution and registration of deeds.

Do not rely on an oral promise for land. Transfers and settlements affecting real property require legally sufficient documentation and registration to protect the parties and affect third persons.

For married spouses, liquidation must follow the applicable marital-property rules and may be part of proceedings involving nullity, annulment, legal separation, judicial separation of property, or the settlement of an estate.

Death and inheritance

A surviving legal spouse may have rights both from liquidation of the marital property and from succession. These are separate computations: the survivor’s own share is identified first, while only the deceased spouse’s share enters the estate.

An unmarried partner is not treated as a surviving spouse merely because the couple lived together for many years or had children. The partner must first establish any personal ownership or co-ownership. The deceased partner’s remaining share then passes under a valid will or the rules of intestate succession.

An unmarried partner who wants to provide for the other should obtain advice about a valid will, beneficiary designations, insurance, ownership structure, and the disposable portion of the estate. Compulsory heirs and restrictions on donations can limit what may validly be transferred.

Children’s inheritance rights are distinct from the surviving partner’s rights. The existence of common children does not turn the surviving partner into a legal spouse or automatic intestate heir.

Evidence to preserve

Collect originals or secure copies as early as possible:

PSA marriage certificate, advisory on marriages, or CENOMAR where relevant;
marriage settlement and proof of registration;
certificates of title and current certified true copies;
deeds of sale, donation, assignment, or mortgage;
vehicle registrations and sales documents;
loan applications, promissory notes, amortization records, and statements of account;
bank, investment, and e-wallet records;
official receipts, invoices, tax declarations, and real-property tax receipts;
payroll records, remittance slips, and proof of transfers;
construction contracts, building permits, and materials receipts;
business registrations, books, financial statements, and ownership records;
proof of inheritance or the donor’s written conditions;
messages or agreements identifying the intended shares;
proof of the beginning, exclusivity, and end of cohabitation; and
evidence of childcare, household management, work in a family business, or other relevant contribution.

For land, obtain a current certified true copy rather than relying on a photograph of an owner’s duplicate title. The LRA eSerbisyo Portal accepts online requests for certified true copies. Civil-registry documents may be requested through the Philippine Statistics Authority.

Keep lawful backups outside devices or premises controlled by the other party. Do not alter records, enter an account without authority, secretly take originals that do not belong to you, or manufacture evidence.

Practical steps when ownership is disputed

Do not sign immediately. Avoid signing a waiver, quitclaim, deed of sale, extrajudicial settlement, loan, or authority to sell until its effect is independently explained.
Secure the records. Obtain certified titles, civil-registry documents, loan records, and proof of payment.
Prepare an asset-and-debt timeline. List each asset, acquisition date, registered owner, purchase price, source of funds, current debt, possession, and supporting documents.
Identify the likely regime. Check the marriage date, settlement, validity of the marriage, legal capacity of the partners, and exclusivity of cohabitation.
Check for urgent transactions. Determine whether a sale, mortgage, withdrawal, transfer, foreclosure, or title registration is pending.
Request an accounting where appropriate. Include rent, business income, withdrawals, taxes, loan payments, repairs, and sale proceeds.
Explore a documented settlement. Any settlement should use the correct deed, tax treatment, spousal consent, notarization, and registration process.
Consult the proper professional. A Philippine lawyer should review disputed ownership, a pending sale, a void marriage, competing heirs, concealed assets, or substantial property. Tax and accounting advice may also be needed.

There is no single filing deadline covering every property dispute. Prescription depends on the cause of action, the documents, possession, repudiation of co-ownership, fraud, registration, and the remedy requested. Do not delay while trying to identify a universal deadline.

Common mistakes

Assuming that the name on the title conclusively determines ownership.
Assuming that every asset acquired during marriage is common without checking statutory exclusions.
Treating a long live-in relationship as automatically equivalent to marriage.
Invoking Article 147 without proving legal capacity and exclusive cohabitation.
Invoking Article 148 without proving an actual contribution to the specific property.
Confusing payment of ordinary household expenses with payment toward acquisition of an asset.
Selling, mortgaging, or withdrawing common property without required consent.
Believing physical separation automatically terminates the marital regime.
Dividing assets without accounting for outstanding loans, reimbursements, taxes, or exclusive funds.
Relying on screenshots, photocopies, or oral promises when certified and registered documents are available.
Waiting until property has been transferred to an alleged buyer or creditor before seeking advice.
Assuming an unmarried partner will automatically inherit.

When legal help is urgent

Seek prompt legal assistance if:

a sale, mortgage, foreclosure, auction, withdrawal, or transfer is imminent;
someone is forging a signature or using a false authority;
a title, vehicle, business interest, or account is being secretly transferred;
original documents are being withheld or destroyed;
an estate is being settled without disclosing a possible co-owner or heir;
you received a summons, subpoena, demand letter, or notice from a Registry of Deeds, lender, court, prosecutor, or barangay;
the other party is threatening eviction, dispossession, or removal of children;
assets are being concealed through relatives, corporations, or new accounts; or
financial control is accompanied by threats, intimidation, stalking, or violence.

Economic abuse against a woman or her child may fall under the Anti-Violence Against Women and Their Children Act, depending on the acts and relationship involved. Relief may include a barangay protection order or a court-issued temporary or permanent protection order. Under the statute, a barangay protection order is effective for 15 days, a temporary protection order for 30 days, and a permanent protection order remains effective until revoked by the court upon the protected person’s application. Immediate danger should be reported to emergency services, the nearest police Women and Children Protection Desk, barangay VAW desk, prosecutor, or Family Court.

Frequently asked questions

Is property bought during marriage always owned equally?

Not always. Its classification depends on the governing regime and any exclusion. Under absolute community or conjugal partnership, acquisition during marriage may trigger a presumption of common ownership, but inheritance, donation, exclusive funds, and other statutory circumstances can rebut or avoid that result.

If the title is only in my spouse’s name, do I have rights?

Possibly. A title in one name is important but may not overcome the applicable marital-property presumption. The acquisition date, deed, source of funds, marriage regime, and any exclusions must be checked.

I paid all the monthly amortizations. Is the property solely mine?

Not necessarily. Payments may have come from community or conjugal income even if made from an account in your name. Conversely, traceable exclusive funds may support a reimbursement or ownership claim. The loan, deed, account history, and governing regime must be reviewed together.

Does staying home to care for the family count as a contribution?

Under Article 147, care and maintenance of the family and household expressly count as joint contribution. Under Article 148, actual contribution of money, property, or industry must be proved; the special household-care rule in Article 147 should not be assumed to apply.

Can my live-in partner sell our jointly acquired property without me?

It depends on the ownership structure and governing rule. Article 147 restricts either partner from disposing of their share in property acquired and owned in common during cohabitation without the other’s consent until cohabitation ends. Other co-ownership and registration rules may apply outside Article 147.

Can a spouse sell inherited land without the other spouse?

Inherited property given to one spouse is generally exclusive, but the documents, property regime, donor’s or testator’s terms, improvements, and family-home rules may affect the transaction. Buyers and lenders often require documents establishing the property’s exclusive character.

Does a live-in partner automatically inherit after many years together?

No. Cohabitation alone does not make the survivor a legal spouse or automatic intestate heir. The survivor may own a proven share of co-owned property, but the deceased’s share is governed by a valid will and succession law.

Can partners simply agree to divide everything themselves?

They may settle genuine property claims, but the agreement must respect compulsory heirs, creditors, tax obligations, marital-property restrictions, and formalities for land and other registered assets. A settlement cannot safely transfer real property through an informal handwritten division alone.

What if one partner was already married?

Article 148 will generally be central to the unmarried partners’ property dispute, and actual joint contribution must be proved. The married partner’s share may accrue to the property regime of the valid marriage. Competing claims should be examined before any sale or settlement.
