Quick answer

Marriage does not make every asset “conjugal,” and living together without marriage does not automatically leave a partner with no property rights.

For validly married couples, ownership depends primarily on the marriage settlement, the date of marriage, how and when the property was acquired, and whether it falls within an exclusion. For most marriages celebrated on or after August 3, 1988 without a valid marriage settlement, the default is absolute community of property. For many earlier marriages, the default was conjugal partnership of gains.

For unmarried couples, the result depends on whether the partners were legally free to marry each other and lived exclusively as spouses:

Under Article 147, qualifying partners generally share wages, salaries, and property acquired through their joint efforts; household and family care can count as a contribution.
Under Article 148, which commonly applies when one or both partners are married to someone else, co-ownership exists only over property acquired through proven actual joint contributions of money, property, or industry.
Relationships outside the statutory wording of Articles 147 and 148 generally depend on title, contracts, ordinary co-ownership rules, and proof of contribution.

A title in only one person’s name is important evidence, but it does not always settle the issue. Conversely, paying expenses or living in a property does not automatically create ownership. The governing regime and supporting documents must be examined.

First identify the governing property regime

Valid marriages on or after August 3, 1988

The Family Code, Articles 74–148 governs the usual civil-law rules.

A valid marriage settlement executed before the wedding controls, provided it is valid and properly registered where required. Future spouses may choose absolute community, conjugal partnership of gains, complete separation, or another lawful arrangement.

Without a valid marriage settlement, the default is absolute community of property.

An informal “prenup” signed after the wedding ordinarily cannot replace the existing regime. Separation of property during marriage generally requires a court order, although spouses may jointly petition for voluntary dissolution of the community or conjugal partnership.

Marriages before August 3, 1988

In the absence of a valid marriage settlement, these marriages were generally governed by the Civil Code’s conjugal partnership of gains. Family Code provisions may apply supplementarily, but vested rights acquired under earlier law must be respected.

The exact dates of the marriage, acquisition, payment, transfer, and disputed transaction can therefore be decisive.

Muslim marriages covered by the Muslim Code

The ordinary Family Code default may not apply. Under Articles 38–42 of the Code of Muslim Personal Laws, the default is generally complete separation of property unless the marriage settlements or another applicable agreement provide otherwise. Applicability depends on the parties and how the marriage was solemnized.

Foreign spouses, foreign property, and foreign divorces

Nationality and the location of property may change the analysis. Philippine law generally governs Filipino spouses’ property relations, subject to Family Code exceptions concerning alien spouses, contracts, and property abroad.

A foreign divorce or judgment may also require recognition by a Philippine court before it can be relied on to alter civil status or official records. Obtain advice before selling or partitioning property based solely on foreign documents.

Absolute community of property

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

Important exclusions include:

Property acquired by one spouse through inheritance, donation, or another gratuitous transfer, unless the donor or testator expressly included it in the community
Property for one spouse’s personal and exclusive use, although jewelry forms part of the community
Property owned before marriage by a spouse who has legitimate descendants from a former marriage, including the fruits and income specified by Article 92
Other property excluded by a valid marriage settlement

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

Conjugal partnership of gains

Under this regime, each spouse generally retains property owned before the marriage. The partnership ordinarily includes:

Earnings from either spouse’s work, profession, business, or industry
Property bought during marriage using conjugal funds
Fruits and income received during marriage from common property
Net fruits from each spouse’s exclusive property
Certain acquisitions by chance, occupation, or other means identified in the Family Code

Property acquired during marriage is presumed conjugal even if registered in only one spouse’s name, unless contrary evidence establishes its exclusive character.

Property inherited or donated to one spouse is generally exclusive. Property purchased entirely with that spouse’s proven exclusive funds may also remain exclusive, subject to tracing and reimbursement rules.

Installment purchases and improvements on exclusive land require special analysis. Ownership can depend on when title vested, what funds were used, the property’s value before improvement, the cost of improvement, and any resulting increase in value.

Complete separation of property

When validly chosen before marriage—or ordered by a court during marriage—each spouse generally owns, administers, enjoys, and disposes of their separate estate. Each spouse also keeps their earnings and the fruits of their property.

Both spouses must still contribute to family expenses in proportion to their income or, when appropriate, the value of their separate properties. Their liability to creditors for family expenses may be solidary.

Complete separation does not necessarily mean there can be no jointly owned property. Spouses may still acquire a particular asset as co-owners according to the deed and their agreement.

Management, sale, and mortgage of marital property

Community or conjugal property is administered jointly.

One spouse’s inability to participate may allow the other to administer the property, but that authority does not automatically include selling, donating, or mortgaging it. A disposition or encumbrance normally requires:

The other spouse’s written consent, or
Court authority when the law permits it

Without either, the disposition or encumbrance is void under Articles 96 and 124. It may operate only as a continuing offer that can become binding if the other spouse accepts, or the court authorizes it, before withdrawal.

The Supreme Court applied these rules to an unauthorized transfer of conjugal property in Alexander v. Spouses Escalona, G.R. No. 256141, July 19, 2022.

A spouse may generally dispose of genuinely exclusive property without the other spouse’s consent under the conjugal-partnership or separation-of-property rules. But the claimed exclusive character should be supported by deeds, inheritance records, bank records, or other tracing evidence.

Separation does not automatically end the marital property regime

Simply moving out, ending the relationship, or maintaining separate households does not dissolve an absolute community or conjugal partnership. Income and acquisitions may remain governed by the existing regime.

If consent is needed for a transaction while the spouses are separated, judicial authority may be sought through a summary proceeding.

Judicial separation of property may be available for statutory causes, including abandonment, abuse of administrative authority, or factual separation for at least one year when reconciliation is highly improbable. Spouses may also jointly file a verified petition for voluntary dissolution of their common property regime. Creditors must be identified and protected.

A decree of judicial separation of property changes the property regime but does not by itself dissolve the marriage.

Property rights of unmarried partners

Article 147: partners legally free to marry each other

Article 147 applies when a man and a woman:

Are legally capacitated to marry each other
Live exclusively with each other as spouses
Are unmarried to each other or are in a marriage void from the beginning

During the qualifying cohabitation:

Their wages and salaries are owned in equal shares.
Property acquired through their work or industry is governed by co-ownership.
Property acquired while they lived together is presumed to have resulted from their joint efforts and is generally owned equally, unless contrary evidence proves otherwise.
A partner who did not earn income may still be considered to have contributed through care and maintenance of the family and household.

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

When a marriage is declared void, the property is not liquidated as an ordinary marital community. Articles 147 or 148 and the Civil Code rules on co-ownership apply. The Supreme Court confirmed that partition may be accomplished by agreement or judicial proceedings and is not necessarily a prerequisite to the declaration of nullity in Soto v. Reyes-Soto, G.R. No. 249759, April 22, 2026. See also Chan Tee Ten v. Tee Ten, G.R. No. 259322, August 6, 2025.

Article 148: a legal impediment or other non-qualifying cohabitation

Article 148 commonly covers:

A relationship in which one partner remains validly married to another person
Bigamous relationships
Adulterous or concubinage relationships
Multiple alliances
Other cohabitation that does not meet Article 147’s requirements

Only property acquired through the partners’ actual joint contribution of money, property, or industry is co-owned. Their shares follow their proven contributions.

Equal shares are presumed only after actual joint contribution has been established. The presumption does not create co-ownership where no contribution has been proved. Unlike Article 147, ordinary household care is not automatically treated as a substitute for the actual contribution Article 148 requires.

The Supreme Court emphasized this evidentiary requirement in Dultra Vda. de Canada v. Baclot, G.R. No. 221874, July 7, 2020. A claimant must prove ownership or contribution; speculation that the titled owner could not have afforded the property is insufficient.

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. This does not automatically transfer the other partner’s independently proven share.

Partners not covered by the statutory wording

Articles 147 and 148 are worded for a man and a woman living together as spouses. Other unmarried partners generally must rely on the Civil Code, including rules on:

Ownership shown by the deed or title
Express or implied contracts
Ordinary co-ownership
Partnership, agency, loan, trust, or reimbursement, when the required elements are proved
Succession and valid wills

For major purchases, the deed should clearly identify each owner and the intended shares. A private agreement should also address loan payments, improvements, expenses, sale, buyout, and separation. It cannot override constitutional restrictions, compulsory-heir rights, creditors’ rights, tax laws, or registration requirements.

Does the name on the title decide ownership?

Not always.

For spouses, property acquired during marriage may be presumed community or conjugal even if the title names only one spouse.

For unmarried partners, a title in one person’s name is strong evidence, but a claimant may try to prove co-ownership through the governing law and competent evidence. The burden is especially demanding under Article 148.

A title also does not validate a transfer prohibited by law. For example, a deed signed by only one spouse may be void if the property was community or conjugal and the required consent or court authority was absent.

Do not rely only on the words “married to,” “single,” or “exclusive property” appearing on a title. Those descriptions may be evidence, but the acquisition date, source of funds, governing regime, and underlying deed must also be examined.

Debts and obligations

Under absolute community or conjugal partnership, common assets may answer for obligations expressly listed in the Family Code, including family support, taxes and expenses on common property, debts agreed to by both spouses, and debts incurred by one spouse to the extent the family benefited.

A purely personal debt is not automatically a common obligation. Liability may depend on consent, family benefit, the nature of the debt, available exclusive property, and reimbursement upon liquidation.

For unmarried partners, cohabitation alone does not make every debt joint. Liability may arise from signing as borrower, co-borrower, guarantor, or mortgagor; from agency or partnership; from expenses chargeable to co-owned property; or from another proven legal basis.

Before signing a loan or using shared property as collateral, confirm:

Who is the borrower
Who owns the collateral
Whether spousal or co-owner consent is required
Whether the document creates solidary liability
Whether the proceeds will benefit the family or common property

The family home has special but limited protection

A family home is generally constituted when a qualifying house and lot are actually occupied as the family residence. It may be created by spouses or by an unmarried head of a family on qualifying property.

It is not an unlimited shield against creditors. Statutory exceptions include:

Nonpayment of taxes
Debts incurred before constitution of the family home
Debts secured by a mortgage on the premises
Certain debts owed to persons who provided labor, services, or materials for its construction

Article 157 still states maximum protected values of ₱300,000 in urban areas and ₱200,000 in rural areas, subject to its currency-change clause and any later adjustment by law. The claim and its value must be proved; present market value alone should not be assumed to be fully exempt.

The Supreme Court explained the requirements and limitations in Ortiz-Aquino v. Aquino, G.R. No. 257235, November 8, 2023. A family home generally cannot be established on property belonging to an unrelated third person merely because the family resides there.

Its voluntary sale or encumbrance may also require written consent under Article 158, including consent from the spouse and the majority of qualified beneficiaries of legal age, subject to court resolution of a conflict.

What happens when the relationship ends?

For valid spouses

The property regime is normally liquidated when it terminates through death, legal separation, annulment, declaration of nullity, or judicial separation of property.

Liquidation generally involves:

Preparing an inventory separating common and exclusive property
Identifying reimbursements and advances
Paying community or conjugal debts
Returning exclusive property
Dividing the net community assets or conjugal gains
Addressing forfeiture, children’s presumptive legitimes, and the family dwelling when legally applicable

A private division made while the marital regime is still operating may be invalid. Do not execute a quitclaim or deed of partition without confirming that the regime has lawfully terminated or been judicially dissolved.

For Article 147 or 148 partners

When cohabitation ends, the parties should account for and partition co-owned property under the Civil Code.

They may agree on a buyout, physical division, assignment, or sale. Real-property arrangements must use the proper public instruments and comply with tax and registration requirements.

If they cannot agree, a co-owner may generally seek judicial partition, accounting, recovery of possession, reconveyance, or other appropriate relief. If the property cannot be divided without seriously impairing it and no co-owner will acquire the others’ interests, the court may order its sale and division of the proceeds.

Ending the relationship does not by itself change the title or erase the co-ownership.

Death and inheritance

A surviving legal spouse normally has two distinct interests:

The spouse’s own share resulting from liquidation of the marital property regime; and
The inheritance due from the deceased spouse’s estate under the Civil Code

The surviving spouse is generally a compulsory heir, subject to legal separation, disinheritance, renunciation, and other succession rules. The share depends on which children, parents, or other heirs survive and whether there is a valid will.

An unmarried partner is not automatically a compulsory or intestate heir. The survivor keeps any independently owned or co-owned share but does not automatically inherit the deceased partner’s share. A valid will may benefit the partner only from the portion the deceased could freely dispose of after satisfying compulsory heirs. Certain donations between cohabiting partners are also prohibited by Articles 87 of the Family Code and 739 of the Civil Code.

When a married person dies, Articles 103 and 130 require liquidation of the community or conjugal property in the estate proceeding. If no judicial estate proceeding is opened, the surviving spouse must liquidate it judicially or extrajudicially within six months from death. After that period, a disposition or encumbrance involving the unliquidated common property is void. Contracting a later marriage without the required liquidation also triggers a mandatory complete-separation regime for the later marriage.

Seek advice promptly because estate, tax, publication, and registration requirements operate alongside this six-month rule.

Foreign nationals and Philippine land

Marriage or cohabitation does not override the constitutional restriction on land ownership.

Under Article XII, Sections 7–8 of the Constitution, a foreign national generally cannot acquire Philippine private land except through hereditary succession or another constitutional exception. Former natural-born Filipinos have separate statutory rights subject to limits.

Using a Filipino spouse or partner as a nominal owner to evade the restriction can create serious consequences. A foreign contributor may also be unable to recover funds advanced for an unconstitutional acquisition, as discussed in Muller v. Muller, G.R. No. 149615, August 29, 2006. Obtain Philippine property advice before paying a reservation fee or purchase price.

Practical steps to protect your position

1. Classify the relationship before negotiating

Confirm:

The date and validity of the marriage, if any
Whether a marriage settlement exists
Whether either partner was married to someone else during cohabitation
Whether the cohabitation was exclusive
Whether the Muslim Code, foreign law, or constitutional land restrictions may apply
The acquisition and payment dates for every disputed asset

2. Prepare an asset-and-debt inventory

List land, condominium units, vehicles, businesses, shares, bank accounts, insurance, pensions, loans, appliances, jewelry, digital assets, receivables, and major improvements. Record the titleholder, acquisition date, price, present possession, funding source, and outstanding debt.

3. Preserve evidence

Keep originals and secure digital copies of:

PSA marriage and death certificates and records of previous marriages
Marriage settlements and registration records
Titles, deeds, tax declarations, surveys, and certified Register of Deeds records
Loan, mortgage, and installment documents
Bank statements, remittance records, electronic transfers, payslips, and deposit slips
Receipts for down payments, construction, repairs, taxes, and insurance
Business records and shareholder documents
Messages or emails describing ownership, repayment, or intended shares
Proof of cohabitation and its beginning and end
Evidence of household and family care relevant to Article 147
Photographs and dated inventories of movable property

Preserve complete conversations, not isolated screenshots. Keep backups and do not alter metadata.

4. Check for recent transfers or encumbrances

Obtain updated certified title records when land is at risk. Review annotations, mortgages, adverse claims, notices of levy, and pending deeds. A tax declaration is not a substitute for a title search.

5. Put objections and proposed arrangements in writing

A written objection can help document lack of consent, but it does not by itself cancel a deed, freeze an account, or annotate a title. For a settlement, specify the property, shares, debts, reimbursements, possession, transfer date, taxes, and consequences of default.

6. Use the correct instrument and registration process

A private list or chat agreement may not transfer registered land. Depending on the transaction, the parties may need a notarized deed, tax clearances, lender consent, corporate approvals, and registration with the Register of Deeds or another agency.

7. Seek court protection when necessary

Potential remedies include judicial separation of property, accounting, partition, injunction, receivership, authority to administer property, cancellation or declaration of invalidity of a deed, reconveyance, or preservation of assets. Jurisdiction and venue depend on the relationship, property, assessed value, and relief requested. Family Courts have authority over specified marital and cohabitation property disputes under the Family Courts Act.

Common mistakes

Assuming that everything becomes common property upon marriage
Assuming that the person named on the title always owns the asset exclusively
Treating a long relationship as legally equivalent to marriage
Claiming equal shares under Article 148 without first proving actual contribution
Believing that homemaking is automatically sufficient under Article 148 because it can count under Article 147
Assuming that moving out ends a marital property regime
Selling or mortgaging the entire property without the required spouse or co-owner consent
Signing a quitclaim, waiver, extrajudicial settlement, or deed without an inventory and valuation
Treating payment of utilities or ordinary living expenses as conclusive proof of ownership
Building on land owned by a partner or the partner’s parents without a written agreement
Relying on an unrecognized foreign divorce or an unofficial claim that a marriage was void
Hiding, destroying, transferring, or withdrawing assets after a dispute begins

When legal help is urgent

Consult a Philippine lawyer immediately if:

A sale, mortgage, foreclosure, title transfer, or account withdrawal is imminent
A deed appears to contain a forged signature or false marital status
Original documents, vehicles, cash, or business assets are being removed
A spouse or partner has died and common property remains unliquidated
You receive a summons, demand, levy, foreclosure notice, or Register of Deeds notice
The property involves a foreign national, multiple marriages, an estate, a corporation, or land registered to relatives
There is coercion, stalking, threats, property destruction, or financial control

Economic abuse and deliberate control of a woman’s money, property, work, or personal belongings may fall under the Anti-Violence Against Women and Their Children Act. Available relief may include a barangay protection order or a court-issued temporary or permanent protection order. A court may grant temporary possession of a residence, vehicle, or essential belongings for safety purposes even while final ownership remains unresolved. The Philippine Commission on Women’s official helpline page lists current assistance channels.

FAQ

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

Not necessarily. A marital presumption, Article 147, Article 148, or ordinary co-ownership may apply. You will need evidence of the governing relationship, acquisition date, source of funds, contribution, and relevant agreements.

Does paying the down payment make me an owner?

It may support a claim, but it is not conclusive. The deed, title, agreement, legal capacity, source of later payments, and applicable property regime must also be examined.

Is there a minimum number of years before unmarried partners acquire rights?

Articles 147 and 148 state no fixed minimum period. The nature of the cohabitation and the acquisition or contribution evidence matter more than an anniversary date.

Can one co-owner sell the property?

A co-owner ordinarily cannot sell the entire co-owned property without the other owners. The rules for selling an undivided share differ depending on whether Article 147 still restricts disposition during cohabitation, Article 148 applies, or ordinary Civil Code co-ownership governs.

Do children automatically own part of their parents’ property while the parents are alive?

Generally, no. Children may have rights to support and future inheritance, but an expected inheritance is not present ownership. Specific forfeiture and presumptive-legitime provisions can apply in certain marital or void-marriage proceedings.

Can an unmarried partner inherit without a will?

Generally, no. The partner first keeps any proven personal or co-owned share. The deceased partner’s share passes under succession law, not automatically to the surviving partner.

Can a partner be removed from the home simply because the title is in the other person’s name?

Ownership and immediate possession are separate questions. Lease rights, co-ownership, family-law orders, protection orders, and due process may affect possession. Avoid forcible self-help and obtain urgent advice where safety or eviction is involved.
