Quick answer

Marriage does not automatically make every asset “conjugal,” and living together does not automatically give each partner half of everything.

For married couples, ownership depends first on any valid marriage settlement and then on the property regime imposed by law. Most marriages celebrated under the Family Code without a prenuptial agreement are governed by absolute community of property, while many earlier marriages are governed by the conjugal partnership of gains. Complete or partial separation of property may also apply.

For unmarried partners, the rules depend on whether they were legally free to marry each other:

If a man and a woman were capacitated to marry each other and lived exclusively as spouses, Article 147 generally creates a special co-ownership, with household and family care recognized as a contribution.
If a legal impediment existed—such as a subsisting marriage to someone else—Article 148 generally recognizes co-ownership only to the extent of proven actual contributions.
The Supreme Court has also recognized property co-ownership claims between same-sex live-in partners under Article 148, based on evidence of actual contribution.

The name appearing on a title, deed, bank account, registration certificate, or receipt is important evidence, but it may not by itself settle whether an asset is community, conjugal, exclusive, or co-owned. The governing regime, acquisition date, source of funds, contributions, and relevant documents must all be examined.

First determine which property regime applies

For spouses, the order is:

A valid marriage settlement executed before the wedding;
The applicable provisions of the Family Code or earlier law; and
Local custom, in the limited situations where it is legally relevant.

A marriage settlement must be in writing, signed, and executed before the marriage. To bind third persons, it must also be registered in the local civil registry where the marriage contract is recorded and in the proper property registries. Once the marriage has taken place, spouses ordinarily cannot create a new separation-of-property regime through a simple private agreement; judicial action may be required. See Articles 74–81 of the Family Code.

The date of the marriage matters. In broad terms:

For marriages celebrated under the Family Code without a marriage settlement, the default is absolute community of property.
A conjugal partnership of gains may exist because it was selected in a marriage settlement or because the marriage and vested property rights arose under earlier law.
Muslim marriages covered by the Code of Muslim Personal Laws follow a different framework. In the absence of a contrary settlement or contract, the default is generally complete separation of property under Articles 37–44 of Presidential Decree No. 1083.

Nationality, the location of property, foreign marriages, prior marriages, and foreign divorce decrees can also change the analysis.

Absolute community of property

Under absolute community, the starting rule is that property owned by either spouse when the marriage begins, and property acquired afterward, belongs to the community. Property acquired during the marriage is presumed community property unless an exclusion is proved.

Important exclusions include:

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

These rules appear in Articles 88–93 of the Family Code.

This means a house inherited by one spouse during the marriage is ordinarily that spouse’s exclusive property. By contrast, a house purchased before the wedding may enter the absolute community unless it falls within an exclusion or a valid marriage settlement provides otherwise.

Who controls community property?

Administration and enjoyment belong to both spouses jointly. One spouse’s inability to participate may allow the other to administer, but administration alone does not include the unrestricted power to sell, mortgage, or otherwise encumber community property.

A sale or mortgage requiring the other spouse’s written consent or court authority is void when neither exists. The Family Code treats the attempted transaction as a continuing offer that may still become binding if the other spouse accepts, or the court authorizes it, before the offer is withdrawn. See Articles 96–98 of the Family Code.

Conjugal partnership of gains

Under the conjugal partnership of gains, each spouse generally retains property brought into the marriage. The partnership ordinarily includes earnings, income, fruits, and property acquired for value during the marriage using partnership funds.

Exclusive property generally includes:

Property owned before marriage;
Property acquired during marriage by inheritance or donation;
Property acquired by redemption, barter, or exchange using one spouse’s exclusive property; and
Property purchased with one spouse’s proven exclusive money.

Property acquired during the marriage is nevertheless presumed conjugal unless the contrary is proved. Registration in only one spouse’s name does not automatically defeat that presumption. Articles 105–120 of the Family Code govern these distinctions.

Installment purchases and improvements

Timing and payment records are especially important when:

An asset was purchased on installment before and during the marriage;
One spouse’s exclusive funds and common funds were both used;
Community or conjugal money paid a mortgage on separately owned property; or
Common funds or labor improved one spouse’s land.

Depending on when ownership vested and the relative values involved, the result may be ownership by one spouse or by the partnership, together with a right to reimbursement upon liquidation. It is unsafe to assume that making some payments automatically creates a proportional ownership share.

Disposing of conjugal property

As with absolute community property, both spouses jointly administer the conjugal partnership. A disposition or encumbrance made without required written consent or court authority is void, subject to the Family Code’s continuing-offer rule. One spouse may generally dispose of genuinely exclusive property without the other’s consent. See Articles 124–125 of the Family Code.

Complete separation of property

Under a valid complete-separation regime, each spouse owns, possesses, administers, enjoys, and disposes of their separate estate and earnings. Neither normally needs the other’s consent to deal with separately owned property.

Both spouses must still bear family expenses in proportion to their income or, if necessary, the value of their separate properties. Their liability to creditors for family expenses is solidary. See Articles 143–146 of the Family Code.

A separation-of-property regime may arise from:

A valid marriage settlement executed before marriage;
A judicial decree during marriage;
Liquidation failures involving an earlier marriage, in the circumstances specified by law; or
The special rules governing certain Muslim marriages.

Separation in fact does not end the marital property regime

Moving out, ending the relationship, or maintaining separate bank accounts does not by itself dissolve an absolute community or conjugal partnership.

The existing regime generally continues until death, annulment, a declaration of nullity, legal separation, or judicial separation of property. When a required consent cannot be obtained because the spouses are separated, judicial authorization may be sought through the appropriate proceeding.

If a spouse abandons the family or fails to perform family obligations, the aggrieved spouse may seek receivership, judicial separation of property, or authority to act as sole administrator. Under the Family Code, absence from the conjugal dwelling for three months, or failure for the same period to provide information about one’s whereabouts, creates only a prima facie presumption of intent not to return; it is not an automatic transfer of ownership. See Articles 99–101 and 126–128 of the Family Code.

Judicial separation of property may also be available when spouses have been separated in fact for at least one year and reconciliation is highly improbable, or on other grounds listed in Article 135.

Unmarried opposite-sex partners who are free to marry: Article 147

Article 147 applies when a man and a woman:

Are legally capacitated to marry each other;
Live exclusively with each other as husband and wife; and
Have no valid marriage, or their marriage is void.

Their wages and salaries are owned in equal shares. Property acquired during the cohabitation through their work or industry is governed by co-ownership rules. Property acquired while they lived together is presumed to have resulted from their joint efforts and to be owned equally unless contrary proof is presented.

Crucially, caring for the family and maintaining the household count as a contribution. A homemaker does not lose a claim merely because the other partner earned the money or signed the purchase documents.

The Supreme Court has emphasized that Article 147 covers property acquired during the actual period of cohabitation, not necessarily everything obtained before the relationship began or after the partners had permanently separated. See Paterno v. Paterno, G.R. No. 213687, January 8, 2020.

While cohabitation continues, neither partner may dispose of or encumber even their share of commonly owned property without the other’s consent. The Supreme Court has treated an unauthorized donation of such property as void. See Perez, Jr. v. Perez-Senerpida, G.R. No. 233365, March 24, 2021.

Article 147 also contains special forfeiture rules when a void marriage involved one party in bad faith. Whether those rules apply requires findings about the marriage’s validity, good faith, and the existence of common children or descendants.

Partners who cannot legally marry each other: Article 148

Article 148 generally applies to cohabitation not covered by Article 147. A common example is a relationship in which one or both partners have a subsisting marriage 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 contributions are proved but their proportions are not, the law presumes equal contributions and equal shares. The same rule applies to joint deposits and evidences of credit.

Unlike Article 147, Article 148 does not create a broad presumption that all property acquired during the relationship resulted from joint effort. The claimant must first prove an actual contribution connected to the asset. Household care alone should not be assumed to have the same automatic treatment it receives under Article 147.

If one partner remains 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. Bad-faith forfeiture rules may also affect a partner’s share. The complete statutory rule appears in Articles 147–148 of the Family Code.

Same-sex partners

Philippine law does not presently treat a same-sex relationship as a marriage. That does not mean a partner’s proven financial or property contribution is legally invisible.

In a decision announced in February 2026, the Supreme Court recognized that same-sex live-in partners may establish co-ownership under Article 148 when the evidence proves actual contribution. The ruling concerns property ownership and does not itself create marital status or all rights incident to marriage. See the Supreme Court’s official summary, SC Recognizes Co-Ownership of Property in Same-Sex Relationships.

Same-sex partners should document purchase contributions, renovation expenses, loan payments, intended percentages, and acknowledgments of ownership. A deed expressly naming both partners and their shares can prevent a difficult evidentiary dispute.

A title in one name is not always conclusive

For married couples under absolute community or conjugal partnership, the Family Code’s presumptions can apply even if property is registered in one spouse’s name.

For unmarried partners, a title in one name is strong evidence but may be challenged by proof of co-ownership, contribution, acknowledgment, trust, or another legally recognized basis. Conversely, cohabitation by itself does not prove an ownership interest in every asset.

Different questions must not be confused:

Ownership: Who legally owns the asset?
Property regime: Is it community, conjugal, exclusive, or co-owned?
Possession: Who currently occupies or controls it?
Loan liability: Who promised the lender that the debt would be paid?
Registration: Whose name appears in official records?
Beneficial interest: Did another person contribute or acquire enforceable rights?

A person can be liable on a loan without owning half the property, or own an interest without being the only person named on a utility bill.

Debts are not automatically shared in every case

Under absolute community or conjugal partnership, obligations incurred by both spouses, or by one spouse with the other’s consent, are generally chargeable to common property. A debt incurred without consent may still be chargeable to the extent the family or common property benefited.

Purely personal debts, fines, gambling losses, and liabilities arising from crime or quasi-delict receive different treatment. Some may initially be paid from common assets only under statutory conditions and later charged against the responsible spouse during liquidation.

For unmarried partners, one person ordinarily does not become liable for the other’s debt merely because they live together. Liability may arise from signing as borrower, co-borrower, guarantor, or mortgagor, or from another valid legal basis.

Donations between spouses or live-in partners require caution

During marriage, direct or indirect donations or grants of gratuitous advantage between spouses are generally void, except moderate gifts on occasions of family rejoicing. Article 87 extends that prohibition to persons living together as husband and wife without a valid marriage.

This rule can affect deeds labeled as donations, waivers without genuine consideration, simulated sales, and transfers intended to evade the prohibition. A document’s title does not control if the transaction is really gratuitous.

A transfer connected with a future marriage has separate rules and may fail if the marriage does not take place. Estate planning should therefore be done through instruments that comply with donation, succession, property, and tax laws.

Rights when a spouse or partner dies

A surviving legal spouse is an intestate and compulsory heir, subject to the succession rules and the rights of other heirs. Before the deceased spouse’s estate is divided, the community or conjugal property must first be identified and liquidated so that only the deceased’s proper share enters the estate.

If no judicial estate proceeding is filed, the surviving spouse must liquidate the absolute community or conjugal partnership judicially or extrajudicially within six months from death. After that period, a disposition or encumbrance of unliquidated common property is void. Remarrying without the required liquidation results in a mandatory complete-separation regime for the subsequent marriage. See Articles 103 and 130 of the Family Code.

An unmarried partner is not automatically an intestate heir merely because the relationship lasted many years or produced common children. The partner may still own a separate or co-owned share; only the deceased’s share becomes part of the estate. A valid will may benefit a partner, but compulsory heirs’ legitimes and legal restrictions must be respected.

Do not transfer, sell, withdraw, or divide disputed estate assets based only on an informal family understanding. Settlement documents, estate taxes, creditor claims, registration, and the participation of all heirs may be required.

What happens when co-owners separate?

Former partners can agree on an orderly partition or sale, provided the agreement is valid, all necessary owners participate, creditor rights are respected, and the required form and registration rules are followed.

If no agreement is possible, a co-owner may bring an action for partition. A complaint concerning real property must state the nature and extent of the claimant’s title, adequately describe the property, and include all other interested persons. A final partition affecting registered land should be recorded with the Registry of Deeds. See Rule 69 of the Rules of Court.

A partition claim is generally not lost merely through the passage of time while the co-ownership remains acknowledged. Prescription may begin, however, after a clear repudiation of the co-ownership that is properly communicated and accompanied by the legally required circumstances. Claims involving fraud, reconveyance, possession, contracts, or damages may follow different limitation periods. Delay can also make evidence disappear, so prompt advice remains important.

If the property cannot be physically divided without seriously harming the parties’ interests, the court may order an appropriate sale and division of proceeds rather than an impractical subdivision.

Practical steps before buying property together

Whether married or unmarried:

Identify the applicable property regime before signing.
Decide who will own the asset and in what shares.
Make the deed, loan papers, and registration documents consistent with that arrangement.
Record the source of the down payment, installments, construction costs, taxes, and improvements.
Keep inherited or donated funds traceable if they are intended to remain exclusive.
Avoid cash payments without receipts or written acknowledgment.
Do not sign a waiver, quitclaim, deed of sale, donation, mortgage, or special power of attorney without understanding its effect.
For unmarried buyers, use a written co-ownership agreement addressing shares, expenses, occupation, rental income, default, buyout, sale, and separation.
Make wills and review beneficiary designations, particularly if the relationship does not create automatic inheritance rights.
Register instruments when registration is required to affect third parties.

A private agreement cannot override mandatory law, defeat compulsory heirs, prejudice existing creditors, or convert an invalid marriage into a valid one.

Evidence to preserve

Keep original documents and secure digital copies of:

Marriage certificate and any marriage settlement;
Birth certificates relevant to prior marriages or heirs;
Court decrees involving nullity, annulment, legal separation, divorce recognition, or property separation;
Certificates of title, tax declarations, deeds, contracts to sell, and condominium documents;
Loan applications, promissory notes, mortgage documents, and amortization schedules;
Bank transfers, deposit slips, official receipts, payroll records, and remittance records;
Proof of inherited or donated funds and the donor’s or testator’s instructions;
Construction contracts, renovation invoices, permits, and photographs;
Messages or signed acknowledgments showing intended ownership shares;
Records of household management and family care when Article 147 may apply;
Lease contracts and records of rent received;
Corporate records if assets were placed in a company;
Insurance policies, wills, beneficiary forms, and estate documents; and
Evidence of threatened sales, withdrawals, concealment, or destruction of property.

Request certified copies from the proper civil registry, Registry of Deeds, court, bank, or government office when authenticity may be disputed.

Common mistakes

Assuming “conjugal” always means 50% of every asset

The property must first be classified, liabilities paid, exclusive-property claims and reimbursements resolved, and any forfeitures applied. Only then can the net share be determined.

Treating physical separation as automatic property separation

The marital property regime ordinarily continues despite living apart.

Relying only on whose name appears on the title

Registration matters, but the acquisition date, funds, governing regime, and statutory presumptions may lead to a different result.

Assuming every live-in partner receives half

Article 147 and Article 148 have materially different requirements. Article 148 generally demands proof of actual contribution.

Hiding a transfer as a sale or waiver

A simulated sale or disguised donation may be invalid and can create civil, tax, or criminal exposure.

Selling first and asking permission later

A required spouse’s consent or court authority cannot safely be treated as a technicality. The attempted disposition may be void.

Dividing only the assets and ignoring debts

Proper liquidation includes an inventory, payment of common obligations, reimbursements, delivery of exclusive property, and division of the net balance.

Waiting until records disappear

Even where partition remains available, bank retention periods, lost receipts, deceased witnesses, and changed possession can make proof much harder.

When legal help is urgent

Consult a Philippine family- or property-law practitioner promptly if:

A sale, mortgage, transfer, foreclosure, or withdrawal is about to occur;
A signature was forged or consent was obtained through fraud, intimidation, or deception;
Property is being concealed, dissipated, transferred to relatives, or moved into a corporation;
A spouse or partner has died and the six-month liquidation period is running;
There are competing spouses, prior marriages, foreign divorces, or questions about marital validity;
You are being forced from the family home or denied access to essential funds or documents;
A deadline in a court order, summons, notice of foreclosure, or tax assessment is approaching;
Minor children, compulsory heirs, creditors, or estate claims are affected; or
There is violence, coercive control, or deliberate deprivation of financial resources.

Economic abuse may fall under the Anti-Violence Against Women and Their Children Act when its statutory elements are present. The law covers a wife, former wife, a woman in a sexual or dating relationship, or a woman who has a common child with the respondent. It provides access to barangay or court protection orders and legal and support services. A mere financial disagreement is not automatically a criminal offense; the precise prohibited act and required elements must be proved.

In immediate danger, contact the Philippine National Police, the barangay VAW desk, local social-welfare authorities, or emergency services. Eligible persons may also seek assistance from the Public Attorney’s Office.

Frequently asked questions

Is property bought before marriage automatically exclusive?

Not always. Under conjugal partnership of gains it is generally exclusive, but under absolute community it may enter the community unless an exclusion or valid marriage settlement applies. Prior descendants, source of acquisition, and the marriage date can matter.

If only one spouse paid, is the property automatically theirs?

No. Earnings and property acquired during marriage may belong to the community or partnership even if only one spouse earned the money. Exclusive ownership requires a legal basis and adequate proof.

Can one spouse sell a titled property without the other’s signature?

A spouse may generally sell genuinely exclusive property. Community or conjugal property ordinarily requires the other spouse’s written consent or court authority. The title being in one name does not by itself establish that the property is exclusive.

Does a live-in partner acquire rights after a certain number of years?

There is no general rule that cohabitation for five, ten, or any other number of years automatically transfers half of all property. The nature of the relationship and evidence of acquisition or contribution control.

Does staying home to raise children 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; household care should not automatically be treated as sufficient without a fact-specific legal assessment.

Can an unmarried partner inherit without a will?

The partner has no automatic intestate share merely because of cohabitation. The partner keeps any proven ownership or co-ownership, but the deceased’s share passes under succession law. Common children may have inheritance rights of their own.

Can partners simply notarize a document saying everything is separate?

Unmarried partners may document ownership and contributions, subject to mandatory law. Spouses cannot ordinarily replace their legal property regime after marriage through a simple notarized agreement; judicial separation of property may be necessary.

Can a co-owner demand partition at any time?

Generally yes, while the co-ownership is recognized. Exceptions, contractual limits, repudiation, prescription of related claims, and restrictions under Article 147 may affect the remedy.
