Quick answer

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

For married couples, ownership depends first on a valid marriage settlement signed before the wedding. Without one, marriages governed by the Family Code generally fall under the absolute community of property, where most property owned at marriage or acquired afterward enters the community, subject to statutory exclusions.

For unmarried partners, the result depends mainly on whether they were legally free to marry each other:

If both were capacitated to marry and lived exclusively as spouses, Article 147 generally recognizes equal shares in wages and salaries and presumes equal co-ownership of property acquired through their joint efforts. Homemaking and caring for the family count as contributions.
If either partner was legally married to someone else, or the relationship otherwise falls outside Article 147, Article 148 applies. Only property acquired through proven, actual joint contributions of money, property, or industry is co-owned, generally in proportion to those contributions.

A title, receipt, or bank account in only one person’s name is important evidence, but it does not always settle the issue. The marriage date, property regime, source of funds, legal capacity to marry, and supporting documents may change the answer.

First identify the relationship and governing property regime

Before deciding who owns an asset, establish:

Whether there is a valid marriage.
When the marriage or cohabitation began.
Whether either person had an existing marriage.
Whether a marriage settlement was signed before the wedding.
When and how the asset was acquired.
Who supplied the purchase money, labor, or other contribution.
Whether the asset was inherited, donated, exchanged, or bought with exclusive funds.

These are not technicalities. They determine which legal rules apply.

Property rights of married couples

Absolute community of property

Under Articles 74–77 of the Family Code, a valid marriage settlement controls if it was properly executed before the wedding. In its absence—or if the agreed regime is void—the Family Code’s default is absolute community of property.

The community generally includes:

Property either spouse owned when the marriage began;
Property acquired by either or both spouses during marriage;
Salaries, business income, and most other acquisitions during the marriage; and
Property registered in only one spouse’s name if the law treats it as community property.

Property acquired during marriage is presumed community property unless the spouse claiming exclusion proves otherwise.

Important exclusions include:

Property inherited by or donated exclusively to one spouse during marriage, including its fruits and income unless the donor or testator expressly included them in the community;
Property for one spouse’s personal and exclusive use, although jewelry is community property; and
Property owned before marriage by a spouse who has legitimate descendants from a former marriage, together with its fruits and income.

Whether a particular asset is excluded depends on its acquisition documents and the source of funds. Mixing inherited or other exclusive money with community funds can create difficult tracing and reimbursement issues.

Conjugal partnership of gains

A couple may choose a conjugal partnership of gains in a valid marriage settlement. This regime may also apply to older marriages, depending on when the marriage was celebrated and the law then governing it.

Under this regime:

Property brought into the marriage generally remains exclusive;
Property inherited or received by donation during marriage generally remains exclusive;
Earnings from either spouse’s work and property acquired at the expense of the common fund are conjugal; and
The net fruits of exclusive property ordinarily enter the conjugal partnership.

Property acquired during marriage is presumed conjugal even if the deed or title names only one spouse. The person claiming exclusive ownership must overcome that presumption with evidence. Articles 105–133 of the Family Code contain the governing rules, including special treatment for installment purchases and improvements made on exclusive property.

Complete or partial separation of property

Future spouses may agree before marriage that their estates will remain separate. Separation may cover present property, future property, or both.

Under complete separation:

Each spouse owns, administers, enjoys, and disposes of their separate estate;
Each keeps earnings from their profession, business, or industry; and
Both remain responsible for family expenses in proportion to their income or, if necessary, the value of their properties.

A private agreement made only after the wedding does not ordinarily replace the existing regime. During marriage, separation of property generally requires a court order, whether sought jointly or for a sufficient statutory cause.

Marriage settlements must be completed before the wedding

A marriage settlement—often called a prenuptial agreement—must be:

In writing;
Signed by the parties; and
Executed before the marriage.

To bind third persons, it must also be registered in the local civil registry where the marriage is recorded and in the appropriate property registries. A post-wedding document simply stating that property will now be separate does not by itself accomplish judicial separation of property.

Can one spouse sell or mortgage common property alone?

Generally, no.

Administration and enjoyment of absolute-community or conjugal-partnership property belong to both spouses jointly. One spouse’s inability to participate may allow the other to administer the property, but that authority does not include selling, mortgaging, or otherwise encumbering common property without:

The other spouse’s written consent; or
Court authority.

Without the required consent or authority, the disposition or encumbrance is void under Articles 96 and 124 of the Family Code. The transaction may remain a continuing offer capable of acceptance or court authorization before it is withdrawn, but parties should not assume that later conduct automatically validates it.

Before signing a sale or mortgage, obtain a current certified title, examine the stated civil status and acquisition date, identify the applicable property regime, and require the legally necessary signatures or court order.

An owner-spouse may generally dispose of genuinely exclusive property under the conjugal-partnership regime without the other spouse’s consent. The evidence must establish that it is truly exclusive.

Separation in fact does not divide marital property

Moving out, starting a new relationship, or living separately for years does not automatically dissolve the absolute community or conjugal partnership.

The marital property regime ordinarily continues until a legally recognized event terminates it, such as:

Death;
A decree of legal separation;
Annulment or declaration of nullity, subject to the applicable liquidation rules; or
Judicial separation of property.

If required consent cannot be obtained because the spouses are separated, judicial authority may be sought through the proceeding allowed by the Family Code. Selling first and arguing about validity later exposes the parties and buyer to serious risk.

A spouse may seek receivership, judicial separation of property, or authority to administer common property when the other spouse abandons the family or fails to meet family obligations. The Code also recognizes specified grounds for judicial separation, including abuse of administrative authority and at least one year of separation in fact when reconciliation is highly improbable.

Property rights of unmarried partners

Article 147: both partners are legally free to marry each other

Article 147 applies when a man and a woman who are capacitated to marry each other live exclusively as spouses without marriage, or under a void marriage falling within the provision.

Its principal rules are:

Wages and salaries are owned in equal shares;
Property acquired through both parties’ work or industry is co-owned;
Property acquired during cohabitation is presumed obtained through joint efforts and owned equally unless contrary proof exists; and
Caring for the household and family counts as a contribution even if that partner had no salary or direct financial input.

Until cohabitation ends, neither partner may dispose of or encumber their share in common property acquired during the union without the other’s consent.

The Supreme Court has explained that property arising from this kind of union is liquidated under ordinary co-ownership rules, rather than the liquidation rules for a valid marriage. See Valdes v. Regional Trial Court, G.R. No. 122749, July 31, 1996.

Article 148: one partner is married to another person or Article 147 does not apply

Article 148 is stricter. It covers cohabitation outside Article 147, including a relationship in which one partner is legally married to someone else.

Only property acquired through the parties’ actual joint contribution of money, property, or industry is co-owned. Their shares follow their respective contributions. Equal contributions and shares may be presumed once actual joint acquisition is established, but a person who cannot prove any actual contribution may receive no share.

Unlike Article 147, unpaid homemaking alone is not automatically treated as a contribution under Article 148. The Supreme Court emphasized the need for proof of actual contribution in Agapay v. Palang, G.R. No. 116668, July 28, 1997.

If one partner is validly married to somebody 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 when a party acted in bad faith. These consequences are highly fact-dependent and should not be resolved through an informal percentage calculation.

What can prove an unmarried partner’s contribution?

Useful evidence may include:

Deeds of sale and contracts to sell;
Official receipts and acknowledgment receipts;
Bank statements, deposit slips, electronic-transfer records, and loan releases;
Amortization schedules and proof of who made each payment;
Payroll records or business records showing the source of funds;
Construction contracts and receipts for materials or labor;
Messages or emails discussing ownership, contributions, or repayment;
Joint-account records;
Tax declarations and condominium or homeowners’ records;
Testimony from sellers, contractors, lenders, or other witnesses; and
Proof of household and family care where Article 147 applies.

A deed naming one partner does not necessarily defeat a well-supported Article 147 claim. Conversely, calling someone a “spouse” in a private document does not prove a valid marriage or an ownership contribution.

Rights when the relationship ends

Unmarried co-owners may agree on a written partition or file an action for judicial partition. Under Articles 494–500 of the Civil Code:

A co-owner generally may demand partition;
Partition may be by agreement or judicial proceeding;
If an asset is essentially indivisible and nobody agrees to take it while paying the others, it may be sold and the proceeds distributed; and
Partition requires an accounting of benefits received, expenses paid, and damage caused by negligence or fraud.

For married couples, liquidation involves an inventory, payment of community or partnership obligations, return of exclusive property, applicable reimbursements, and division of the net remainder. The court handling annulment, nullity, legal separation, or judicial separation of property may need to address these matters. Property rights of creditors and children must also be protected.

Do not use self-help by changing titles, fabricating deeds, hiding assets, emptying joint accounts, or forcibly removing the other person. Possession and ownership disputes should be handled through lawful agreement, registration, or court proceedings.

What happens when one partner dies?

Married spouses

A surviving legal spouse may have rights both in the liquidation of marital property and as an heir. These are different computations: the survivor’s ownership share is identified first, while only the deceased spouse’s share and exclusive property form part of the estate.

If death ends an absolute community or conjugal partnership, liquidation should occur in the estate proceeding. If no judicial estate proceeding is opened, the surviving spouse must liquidate the marital property judicially or extrajudicially within six months from death. After that period, a disposition or encumbrance involving unliquidated community or conjugal property is void. A subsequent marriage without the required liquidation results in mandatory complete separation of property for that later marriage.

Unmarried partners

An unmarried partner is not automatically a compulsory or intestate heir merely because the couple lived together for many years or had children. The survivor may still:

Own an Article 147 or Article 148 share proved under the applicable rules;
Have rights under a valid contract or beneficiary designation; or
Receive property under a valid will, subject to compulsory heirs, legitimes, and legal prohibitions.

Separate the survivor’s ownership claim from any inheritance claim. Property already owned by the survivor does not become part of the deceased partner’s estate merely because the title was in the deceased’s name; however, the claimed ownership must be established with admissible evidence.

Donations between spouses and partners

Article 87 of the Family Code generally voids direct or indirect donations or gratuitous advantages between spouses during marriage, except moderate gifts for family rejoicing. The prohibition also applies to people living together as spouses without a valid marriage.

Do not disguise a donation as a sale or place property in a partner’s name without real payment and expect the arrangement to be enforceable. In Agapay v. Palang, the Court treated the circumstances and source of the purchase money as decisive and applied the statutory prohibitions.

Estate planning, beneficiary designations, co-ownership purchases, and genuine sales require different legal analysis. Obtain advice before transferring valuable property.

Practical steps to protect your position

Get civil-status records. Secure the marriage certificate and, when relevant, records concerning a prior marriage, death, annulment, nullity, or foreign divorce recognition.
Obtain the marriage settlement. Check whether it was executed before marriage and properly registered.
Build an asset timeline. List each property, acquisition date, purchase price, source of funds, current titleholder, debts, and present possession.
Secure official property records. Obtain certified copies of land titles, deeds, tax declarations, vehicle records, corporate documents, and mortgage instruments.
Trace the money. Match payments to bank statements, remittances, loan records, inheritance documents, or sale proceeds from earlier exclusive property.
Preserve digital evidence. Export messages and emails with dates and account details. Keep original devices and unedited files where possible.
Document possession and condition. Photograph valuable items and real property. Record serial numbers and prepare an inventory.
Notify the lawyer about deadlines. Death, threatened sale, foreclosure, eviction, or receipt of court papers can require immediate action.
Use a written settlement. Clearly identify assets, debts, valuations, transfers, taxes, registration duties, and releases. Real-property transfers require the proper form and registration.
Register completed legal acts. A private agreement may not protect the parties against buyers, creditors, or other third persons unless required registrations are completed.

Common mistakes

Assuming every asset acquired during a relationship is automatically divided equally;
Believing registration in one name conclusively determines ownership;
Treating years of separation as an automatic property division;
Applying Article 147 when one partner had an existing marriage;
Claiming an Article 148 share without proof of actual contribution;
Signing a waiver without a complete inventory and valuation;
Selling or mortgaging common marital property without written spousal consent or court authority;
Confusing an unmarried partner’s ownership claim with inheritance rights;
Relying solely on tax declarations or informal receipts when stronger records exist;
Hiding, transferring, or damaging property after a dispute begins; and
Missing the six-month liquidation rule following a spouse’s death.

When legal help is urgent

Consult a Philippine family or property lawyer promptly if:

A spouse or partner is about to sell, mortgage, withdraw, conceal, or transfer property;
A deed appears forged or was signed without required consent;
Foreclosure, eviction, demolition, or auction is imminent;
One partner has died and estate property is being distributed or sold;
There is a prior marriage, disputed marriage validity, or foreign divorce;
Business interests, inherited assets, installment purchases, or mixed funds are involved;
Court papers, a demand letter, or a notice from the Register of Deeds has arrived;
A settlement or waiver is being presented for immediate signature; or
Access to money, housing, documents, or essential belongings is being used to control or threaten a woman or her child.

Economic abuse under Republic Act No. 9262 may include depriving a woman of financial resources or the use and enjoyment of conjugal, community, or commonly owned property; controlling her money; destroying household property; or solely controlling common assets. Protection orders may grant safety-related possession and use of a residence, vehicle, or essential personal effects regardless of ownership, without finally deciding title.

For immediate danger, contact the police or the barangay’s Violence Against Women desk. A Barangay Protection Order addressing covered threats or physical violence is issued on the filing date after an ex parte assessment and lasts 15 days. A court-issued Temporary Protection Order may be issued on the filing date and ordinarily lasts 30 days, subject to extension under the law while the permanent-order case remains unresolved.

Frequently asked questions

Is property titled only in my spouse’s name still community or conjugal property?

It may be. Property acquired during marriage is generally presumed community or conjugal under the applicable regime even when registered in only one spouse’s name. Acquisition date, source of funds, inheritance or donation records, and the marriage settlement must be examined.

I paid the entire down payment before marriage. Is the property exclusively mine?

Not necessarily. Under a conjugal partnership, installment property may turn on when full ownership vested, with reimbursement for exclusive or conjugal amounts advanced. Under absolute community, different inclusion and exclusion rules apply. Review the contract to sell, deed, payment history, and applicable regime.

We lived together for many years. Am I automatically entitled to half?

No. Equal treatment may arise under Article 147, but only if its conditions are satisfied. Under Article 148, actual contribution must be proved. Duration alone does not create a 50% share.

Does household work count as a property contribution?

Yes under Article 147: caring for and maintaining the family and household is treated as a joint contribution. Article 148 instead requires actual joint contribution of money, property, or industry.

Can my spouse sell our house without my signature?

If the house is absolute-community or conjugal-partnership property, disposition generally requires your written consent or court authority. A transaction without it is void under the Family Code. If the property is genuinely exclusive, the answer may differ.

Can an unmarried partner inherit automatically?

Generally, no. Cohabitation alone does not make a partner a legal spouse or automatic intestate heir. The partner may have a separate ownership claim or rights under a valid will, contract, or beneficiary designation.

Can we divide property privately after breaking up?

Unmarried co-owners can generally partition by agreement, subject to proper form, creditor rights, taxes, and registration. Married spouses cannot privately terminate an existing statutory marital regime merely by separating; a court decree or another legally recognized ground is ordinarily required.

Does a property case determine who the deceased partner’s heirs are?

Not always. Ownership, filiation, and heirship may require different proceedings. The Supreme Court noted in Agapay v. Palang that heirship and filiation issues belonging in the proper probate or special proceeding should not simply be decided in an ordinary property-recovery action.
