Quick answer

Marriage does not automatically make every asset “50–50,” and living together does not create a common-law marriage.

For married couples, ownership depends primarily on the valid marriage settlement, the date of marriage, how and when the property was acquired, and the source of payment. Without a valid marriage settlement, marriages celebrated from 3 August 1988 generally fall under the absolute community of property. Earlier marriages generally began under the conjugal partnership of gains, subject to transitional rules and vested rights.

For unmarried partners and parties to a void marriage, there is no absolute community or conjugal partnership. Property may instead be co-owned under Article 147 or 148 of the Family Code. The applicable article—and the evidence required—depends largely on whether the partners were legally free to marry each other and lived exclusively as spouses.

The name appearing on a deed, title, account or receipt matters, but it is not always conclusive. Do not sign a sale, waiver, mortgage, partition or settlement until the governing property regime and each party’s share have been established.

First identify the governing property regime

The following is a practical starting point:

Situation	Usual governing regime	Basic effect
Valid marriage with a valid marriage settlement	The regime chosen in that settlement	It may provide for absolute community, conjugal partnership, complete separation or another lawful arrangement
Valid marriage celebrated on or after 3 August 1988, without a valid settlement	Absolute community of property	Most property already owned at marriage and acquired afterward enters the community, subject to statutory exclusions
Valid marriage celebrated before 3 August 1988, without a settlement	Usually conjugal partnership of gains	Pre-marriage property generally remains separate, while earnings, fruits and acquisitions during marriage generally enter the partnership
Unmarried, legally free to marry each other and living exclusively as spouses	Article 147 co-ownership	Wages are shared equally; qualifying property acquired during cohabitation is presumed jointly acquired and equally owned
One or both partners not legally free to marry, or another union outside Article 147	Article 148 co-ownership	Only property acquired through proven actual joint contribution is co-owned
Marriage governed by the Code of Muslim Personal Laws	Ordinarily complete separation, absent a contrary valid agreement	Different rules may apply under Presidential Decree No. 1083

The controlling provisions are principally found in Articles 74–148 of the Family Code. Muslim marriages within the coverage of Presidential Decree No. 1083 require separate analysis; Article 38 of the Code of Muslim Personal Laws provides for complete separation of property in the absence of a contrary stipulation.

International elements can also change the analysis. Property abroad, spouses who are both foreigners, and contracts executed abroad may fall within the exceptions in Article 80 of the Family Code. A foreign spouse’s ability to acquire Philippine land is also restricted by Article XII, Section 7 of the 1987 Constitution.

Marriage settlements must be completed before the wedding

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

In writing;
Signed by both future spouses; and
Executed before the marriage.

To affect third persons, it must also be registered in the local civil registry where the marriage is recorded and in the appropriate property registries.

An agreement made only after the wedding ordinarily cannot replace the existing community or conjugal regime. During marriage, separation of property generally requires a court order, except where the Family Code expressly allows another procedure. Spouses may jointly petition for voluntary dissolution of their absolute community or conjugal partnership, but creditors and other persons with financial interests must be identified and protected.

Property rights under absolute community

Under absolute community, the starting rule is broad: property owned by either spouse when the marriage begins, and property acquired afterward, belongs to the community.

Important exclusions include:

Property received by one spouse during marriage by inheritance, donation or another gratuitous transfer, unless the donor or testator expressly includes it in the community;
The fruits and income of that gratuitously acquired property, unless the donor or testator provides otherwise;
Property for one spouse’s personal and exclusive use, although jewelry forms part of the community; and
Property owned before marriage by a spouse who has legitimate descendants from a former marriage, together with its fruits and income.

Documentation remains essential. A deed of donation, will, estate-settlement document or proof tracing the purchase price to an excluded asset may decide whether property is community or exclusive.

Property rights under conjugal partnership of gains

Under a conjugal partnership, each spouse generally keeps property owned before marriage. Property acquired during marriage by inheritance or donation also ordinarily remains exclusive.

The partnership generally includes:

Earnings from either spouse’s work, profession or business;
Property bought during marriage using partnership funds;
Fruits and income received during marriage from common property;
Net fruits of each spouse’s exclusive property; and
Property acquired by chance, subject to the specific rules of the Family Code.

Property acquired during marriage is presumed conjugal even if the deed or title names only one spouse. The spouse claiming exclusive ownership must prove the applicable exception and trace the source of the acquisition.

Improvements built on one spouse’s separate land can produce reimbursement claims or, depending on the comparative land value and cost of the improvements, affect ownership of the improved property. Construction records, appraisals, loan documents and proof of who supplied the funds are therefore important.

Complete separation of property

Under a valid regime of complete separation, each spouse generally owns, administers and disposes of their separate estate and keeps their earnings and the fruits of their property.

Both spouses must still contribute to family expenses in proportion to their income or, if necessary, the current value of their separate properties. Their liability to creditors for lawful family expenses is solidary.

A separation-of-property regime does not necessarily mean that the spouses can never become co-owners. They may still acquire a specific property together, subject to the deed, their agreement, contributions and ordinary co-ownership rules.

Title in one name does not always decide ownership

A land title saying “Juan, married to Maria” ordinarily identifies Juan’s civil status; the phrase alone does not make Maria a registered co-owner. Conversely, registration solely in Juan’s name does not necessarily defeat the statutory presumption that property acquired during a valid marriage is community or conjugal.

The Supreme Court applied these distinctions in Tan-Andal v. Andal. The Court also explained that property donated to one party to a void marriage could remain that party’s exclusive property despite the description “married to” on the title.

For land, obtain a current certified true copy of the OCT, TCT or CCT—not merely a photocopy held at home. It may be requested through the Land Registration Authority’s eSerbisyo portal.

Can one spouse sell or mortgage common property alone?

Generally, no. Administration and enjoyment of absolute-community or conjugal property belong to both spouses jointly.

A sale, mortgage or other encumbrance requires the other spouse’s written consent or court authority. Without either, the transaction is void, not merely voidable. The Family Code treats it only as a continuing offer that may become binding if the other spouse accepts it, or a court authorizes it, before the offer is withdrawn.

The Supreme Court applied this rule to an unauthorized mortgage in Homeowners Savings & Loan Bank v. Dailo and to a sale involving forged spousal consent in Spouses Fuentes v. Roca.

Different rules apply when the asset is genuinely the exclusive property of one spouse. Under a conjugal partnership, an adult spouse may ordinarily dispose of their exclusive property without the other’s consent. A qualifying family home, however, may be subject to additional consent requirements under Articles 152–162 of the Family Code.

A buyer or lender should therefore verify:

The marriage date and marriage certificate;
Any registered marriage settlement;
When and how the property was acquired;
The source of the purchase money;
The current title and annotations;
The authenticity and scope of the other spouse’s written consent; and
Any court order authorizing the transaction.

Debts are not automatically shared

A debt incurred by one spouse does not automatically make all common property liable.

Community or conjugal property may answer for obligations contracted by both spouses, by one with the other’s consent, or by one spouse to the extent that the family or property regime actually benefited. Taxes, preservation expenses, family support and other charges specifically listed in the Family Code may also be chargeable to common property.

When a creditor relies on supposed family benefit, the use of the loan proceeds matters. Preserve bank records, invoices, business records, hospital bills, tuition documents and evidence showing whether the money was used for the family or solely for one spouse’s personal purpose.

Living apart does not end the property regime

Informal separation does not dissolve an absolute community or conjugal partnership. Property acquired after the spouses separate in fact may therefore remain subject to the existing regime.

The spouses also cannot safely divide common property through a private handshake or an unregistered waiver while the regime is still in force. Judicial separation of property may be available for grounds including abandonment, abuse of administration, failure to perform family obligations, or factual separation for at least one year where reconciliation is highly improbable. Spouses may also file a joint verified petition for voluntary judicial separation of property.

Property rights of unmarried partners

Unmarried partners do not acquire the status or all rights of legal spouses merely because they have lived together for many years, have children, use the same surname socially or introduced each other as husband and wife.

Their property rights usually depend on either Article 147 or Article 148 of the Family Code.

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

Article 147 generally applies when a man and woman:

Had legal capacity to marry each other;
Lived exclusively with each other as spouses; and
Were unmarried or were parties to a void marriage.

Its principal rules are:

Wages and salaries earned during cohabitation are owned in equal shares.
Property acquired through their work or industry is governed by co-ownership.
Property acquired during cohabitation is presumed to have resulted from their joint efforts and to be owned equally, unless contrary evidence is produced.
Caring for the family and maintaining the household count as a contribution, even if that partner supplied no purchase money.
During cohabitation, neither may dispose of or encumber their share in qualifying common property without the other’s consent.

The presumption is rebuttable. A gift or inheritance received by only one partner, or property proven to have been acquired exclusively without contribution from the other—including household or family care—may remain separately owned. The Supreme Court discussed Article 147 co-ownership in Valdes v. Regional Trial Court and clarified its operation in Tan-Andal.

Article 148: a legal impediment or another non-qualifying union

Article 148 commonly applies where one partner remained validly married to someone else, or where the relationship otherwise did not satisfy Article 147.

The protection is narrower:

Only property acquired through the partners’ actual joint contribution of money, property or industry is co-owned.
Each partner’s share is proportional to the proven contribution.
Equal contributions and equal shares are presumed only after the factual basis for joint acquisition has been established and no contrary proof is presented.
The express household-care deeming rule found in Article 147 does not appear in Article 148. A partner should not assume that unpaid domestic work will automatically establish a share under Article 148.
If one partner is validly married to another person, that partner’s share accrues to the absolute community or conjugal partnership of the valid marriage.
Statutory forfeiture rules may apply where one or both parties acted in bad faith, often in favor of common children.

In Agapay v. Palang, the Supreme Court required proof of actual contribution where one party had a subsisting marriage. A deed naming both partners did not eliminate the need to establish the contribution required by Article 148.

Void marriages require a separate property analysis

A void marriage does not create an absolute community or conjugal partnership. Depending on the legal impediments and circumstances, its property consequences are generally governed by Article 147 or 148.

A marriage declared void for psychological incapacity may fall under Article 147 when the parties were otherwise legally free to marry and lived exclusively as spouses. A bigamous union ordinarily falls under Article 148 because of the subsisting prior marriage.

Good faith, the ground for nullity, common children, the source of each asset and the date of acquisition may affect liquidation and forfeiture. A final judgment declaring the marriage void is also required before either party may remarry.

LGBTQ+ and other relationships not covered by the statutory wording

Articles 147 and 148 are written in terms of a man and a woman living as spouses. A same-sex couple should not assume that the special wage-sharing and contribution presumptions in those provisions will automatically apply.

Property rights may instead have to be established through the deed or title, an enforceable contract, the general co-ownership provisions of the Civil Code, resulting trust principles where properly proved, and evidence of actual contributions. Because the controlling Family Code provisions have gender-specific wording and the outcome can be document-sensitive, careful co-ownership and estate planning is particularly important.

General co-ownership rules

Where property is co-owned, Articles 484–501 of the Civil Code generally provide that:

Benefits and charges follow each co-owner’s proportionate interest;
Shares are presumed equal unless the contrary is proved;
Each co-owner may use the property without injuring the others’ rights;
Preservation expenses and taxes are shared proportionately;
A co-owner may ordinarily transfer their undivided share, but cannot transfer the other co-owner’s share;
No co-owner is generally required to remain indefinitely in co-ownership; and
If an indivisible property cannot be allotted to one co-owner with payment to the others, it may be sold and the proceeds divided.

Article 147 temporarily restricts a partner’s ability to dispose of their share during the cohabitation, so the ordinary right to sell an undivided share must be read together with that special rule.

What happens when an unmarried relationship ends?

Start with an inventory rather than an assumed equal division.

For every asset, record:

The acquisition date;
The registered owner;
The purchase price and financing;
Each payment and its source;
Whether either partner had a subsisting marriage;
Whether the relationship was exclusive;
Each partner’s financial, property or industry contribution;
Who paid taxes, loan installments, repairs and improvements; and
Whether the property was purchased, inherited or donated.

The partners may agree on a documented partition, sale or buyout. If they cannot agree, judicial partition, accounting, reimbursement, recovery of property or other relief may be appropriate. A partition of land must be properly documented, taxed where applicable and registered; notarization alone does not transfer the title.

Transfers arising from a sale, donation or estate ordinarily require tax processing and an electronic Certificate Authorizing Registration before registration. Current requirements are available through the BIR’s eCAR service guidance.

Death and inheritance

A surviving legal spouse normally has two different sets of rights:

Their own share determined through liquidation of the absolute community or conjugal partnership; and
Their possible inheritance from the deceased spouse’s net estate.

If no judicial estate proceeding is filed, the surviving spouse must liquidate the community or conjugal partnership judicially or extrajudicially within six months from death. After that period, a disposition or encumbrance involving the unliquidated property is void. A surviving spouse who remarries without the required liquidation is placed under a mandatory complete-separation regime in the later marriage.

An unmarried partner is not a surviving “spouse” or compulsory heir under the Civil Code. The survivor retains any share they already own or can prove as co-owner, but the deceased partner’s share passes to the deceased’s heirs or validly designated beneficiaries.

A will may help, but it cannot impair compulsory heirs’ legitimes and remains subject to legal disqualifications. Donations and gratuitous transfers between spouses and between persons living together as spouses are also restricted by Article 87 of the Family Code. Civil Code Articles 739 and 1028 impose additional prohibitions involving adultery or concubinage. Estate planning should therefore be reviewed by a Philippine lawyer rather than implemented through a nominal sale or informal transfer.

Evidence to preserve

Keep original documents secure and make readable digital copies of:

PSA marriage certificates and records of prior marriages;
Marriage settlements and proof of registration;
Deeds of sale, donation, partition and extrajudicial settlement;
Current and historical land titles and tax declarations;
Contracts to sell, loan agreements and amortization schedules;
Bank statements, cancelled checks, remittance records and electronic-transfer receipts;
Payroll records and business-income documents;
Construction contracts, plans, permits, receipts and photographs;
Real-property tax receipts and association dues;
Insurance, vehicle, share-of-stock and investment records;
Messages or emails acknowledging ownership, contributions or intended shares;
Household and childcare records relevant to an Article 147 contribution;
Wills, beneficiary designations and estate documents; and
Any written consent, special power of attorney or court authority used in a sale or mortgage.

Do not alter files or access an account unlawfully. Preserve information already lawfully available to you, including metadata and complete message threads.

Practical steps when ownership is disputed

Stop informal transfers. Do not sign a quitclaim, waiver, deed or authority to sell merely to “keep the peace.”
Get civil-status records. Confirm the marriage date, any prior marriage and whether a decree of nullity, annulment, legal separation or foreign divorce was judicially recognized.
Verify the title. Obtain a certified true copy and inspect all mortgages, adverse claims, notices and other annotations.
Build an asset-and-debt timeline. Match acquisition dates and payments to the relationship and marriage history.
Trace the funds. Identify whether money came from earnings, separate property, inheritance, donations, loans or common accounts.
Send a careful written notice if necessary. A lawyer can notify a buyer, bank, developer or registry of the dispute without making unsupported accusations.
Explore a documented settlement. Include ownership, valuation, debts, taxes, possession, sale mechanics and registration obligations.
Obtain tax and registration advice. A transfer between partners may be treated as a sale, donation, estate transfer or partition, with different consequences.
File the correct action promptly if agreement fails. The remedy may involve partition, accounting, declaration of nullity of a contract, recovery, injunction, judicial authority, separation of property or liquidation.

Under the Family Courts Act, Family Courts have jurisdiction over complaints relating to marital status and the property relations of spouses or persons living together under different statuses and agreements. The precise court, venue and filing requirements still depend on the relief and property involved. Barangay conciliation may also be a prerequisite in qualifying disputes, while urgent provisional remedies and other statutory exceptions are treated differently. Civil trial-court filings are subject to the Supreme Court’s current electronic-filing rules.

Common mistakes

Assuming that the person named on the title is always the sole owner;
Assuming that every asset acquired while living together is automatically split equally;
Treating a long relationship as a legal marriage;
Ignoring a partner’s existing valid marriage;
Relying on cash payments without receipts or bank records;
Signing a backdated deed or inventing a purchase price;
Believing that physical separation automatically ends the marital property regime;
Selling only “my half” of undivided marital property while the regime is still in force;
Treating a notarized private settlement as sufficient to change a land title;
Forgetting creditors, mortgages, taxes or compulsory heirs;
Disguising a prohibited donation as a sale; and
Waiting until documents disappear or the property is transferred to another person.

When legal help is urgent

Seek immediate advice if:

A sale, mortgage, foreclosure, withdrawal or transfer is about to occur;
Your signature or written consent was forged;
A title has been surrendered, concealed or replaced;
A spouse or partner is dissipating assets or removing business records;
You received a summons, demand letter, foreclosure notice or notice from the Registry of Deeds;
A spouse has died and the six-month liquidation period is running;
Someone is threatening eviction, violence or destruction of property; or
Financial control is being used to prevent you from leaving or obtaining legal help.

A lawyer may evaluate an injunction, temporary restraining order, receivership, annotation of a pending action or other protective relief. These remedies are fact-specific and should be pursued before the disputed transfer is completed.

For qualified applicants, the Public Attorney’s Office provides legal assistance subject to its rules.

Controlling a woman’s money, depriving her of the use of conjugal or commonly owned property, destroying household property or withholding legally due support may also constitute economic abuse under Republic Act No. 9262. Protection orders can include possession of essential personal effects, support and other safety-related relief. A victim may approach the Barangay VAW Desk, the PNP Women and Children Protection Desk, the local social-welfare office or the appropriate court. Immediate danger should be reported to emergency services.

Frequently asked questions

If a house is titled only in my spouse’s name, do I have rights?

Possibly. The title is important, but property acquired during a valid marriage may be presumed community or conjugal. The marriage date, governing regime, acquisition date and source of funds must be examined.

If I paid the down payment, do I automatically own half of my unmarried partner’s property?

No. Under Article 148, your share ordinarily follows your proven actual contribution. Under Article 147, a presumption of equal joint acquisition may apply, but it can be rebutted. The deed, financing and full payment history matter.

Can my spouse sell common land without my signature?

Generally not. A disposition or mortgage of community or conjugal property without the other spouse’s written consent or court authority is void. Obtain the documents immediately if a transaction has occurred.

Does a live-in partner inherit automatically?

No. An unmarried partner is not an intestate spouse or compulsory heir. The survivor may retain a proven co-owned share, while the deceased’s share passes under succession law or a valid will.

Does moving out end my rights?

No. Moving out does not by itself dissolve a marital property regime or erase an unmarried co-owner’s established share. It may, however, affect evidence of the cohabitation period, exclusivity, possession and expenses.

Who keeps the family home after separation?

There is no automatic answer. Ownership, the applicable property regime, children’s interests, existing loans, possession and the type of court proceeding all matter. A court may order liquidation, partition, sale, reimbursement or temporary possession.

Is there a deadline to challenge an unauthorized sale?

A void contract cannot generally be validated merely by the passage of the ordinary prescription period, and Civil Code Article 1410 states that an action or defense to declare a contract inexistent does not prescribe. However, other claims, procedural remedies, registration issues, evidence loss, good-faith third parties and equitable defenses may complicate the case.

Articles 96 and 124 also contain a specific five-year period for court recourse in the distinct situation where spouses disagreed and a contract implemented one spouse’s decision. Do not assume that period either governs or does not govern your case without a document review. Act immediately.

Can unmarried partners make a written ownership agreement?

Yes, lawful co-ownership and expense arrangements can clarify contributions, shares, use, loan payments and exit procedures. They cannot create a marriage, defeat a valid spouse’s statutory rights, prejudice creditors or compulsory heirs, or validate a prohibited donation. Land arrangements must also comply with formal, tax and registration requirements.
