Quick answer

Marriage does not automatically mean that every asset is split 50–50, and living together does not automatically give an unmarried partner half of the other partner’s property.

For married couples, ownership depends principally on:

the date of the marriage;
any valid marriage settlement signed before the wedding;
the applicable property regime;
when and how the property was acquired; and
whether the property falls within a statutory exclusion.

For unmarried partners and parties to a void marriage, Articles 147 or 148 of the Family Code may create a form of co-ownership. The applicable article depends on whether the partners were legally free to marry each other and lived exclusively as spouses. Article 147 generally provides broader protection, including recognition of homemaking as a contribution. Article 148 is narrower and ordinarily requires proof of actual contribution of money, property, or industry.

A land title, vehicle registration, receipt, or bank account bearing only one person’s name is important evidence, but it does not always settle beneficial ownership. The relationship, acquisition date, source of funds, applicable property regime, and supporting documents must still be examined.

Property regimes for married couples

Under Articles 74 and 75 of the Family Code, spouses may choose their property regime in a marriage settlement executed before the wedding. They may generally select:

absolute community of property;
conjugal partnership of gains;
complete separation of property; or
another lawful arrangement.

To affect third persons, the marriage settlement and any permitted modification must be registered in the local civil registry where the marriage contract is recorded and, when appropriate, in the proper registries of property.

If spouses married on or after August 3, 1988 without a valid marriage settlement, the default regime is generally absolute community of property. Older marriages may be governed by the Civil Code’s conjugal-partnership rules, subject to the Family Code’s retroactive application where vested rights are not impaired. The date of a disputed sale, mortgage, or other transaction can also determine which law applies.

Absolute community of property

Under absolute community, property owned by either spouse when the marriage begins and property acquired afterward generally becomes community property. Important exclusions under Article 92 include:

property acquired during marriage by gratuitous title, such as inheritance or donation, together with its income or fruits, unless the donor, testator, or grantor states that it will belong to the community;
property for the personal and exclusive use of either spouse, although jewelry forms part of the community; and
property acquired before the marriage by a spouse who has legitimate descendants from a former marriage, including its fruits and income.

Property acquired during the marriage is presumed to belong to the community unless it is proved to be excluded. That presumption does not eliminate the need to establish that the property was in fact acquired during the marriage.

Conjugal partnership of gains

Under a conjugal partnership of gains, each spouse generally retains ownership of separate property brought into the marriage. The partnership ordinarily includes the fruits and income of separate properties and property acquired through the spouses’ efforts or at the expense of the common fund.

Article 116 presumes property acquired during the marriage to be conjugal unless the contrary is proved. Among the matters that may rebut the presumption are the acquisition date, source of payment, inheritance documents, donation instruments, and evidence that exclusive funds were used.

When the partnership ends, debts and obligations must first be settled. What spouses divide is the net gain or remainder after proper liquidation—not necessarily one-half of every specific asset while the marriage continues.

Complete separation of property

When a valid marriage settlement establishes complete separation, each spouse generally owns, administers, enjoys, and disposes of his or her own property and earnings. Both spouses must nevertheless contribute to family expenses in proportion to their income or, if that is insufficient, the current market value of their separate properties.

A court may also order separation of property in circumstances allowed by Articles 134 to 138, including certain cases involving abandonment, abuse of administrative powers, prolonged separation in fact, or a spouse’s loss of parental authority. A simple private agreement made after the wedding does not necessarily change the existing property regime.

Management, sale, and mortgage of marital property

Administration and enjoyment of community or conjugal property belong to both spouses jointly. Neither spouse has an automatic right to sell, mortgage, waive, or otherwise encumber common property alone.

Under Articles 96 and 124 of the Family Code, a disposition or encumbrance made without court authority or the other spouse’s written consent is void when the transaction is governed by the Family Code. It is treated as a continuing offer that may become binding if the other spouse accepts it, or a court authorizes it, before either offeror withdraws the offer.

The Supreme Court has emphasized that:

mere knowledge of a transaction is not necessarily written consent;
one spouse cannot ordinarily sell a supposed “half” of an unliquidated conjugal asset because the spouse’s particular share does not vest until dissolution and liquidation; and
a buyer must investigate both the seller’s title and the seller’s authority to dispose of marital property.

These principles are discussed in Dolera v. Spouses Escalona and Spouses Aggabao v. Parulan.

An important historical exception applies to unauthorized dispositions made before the Family Code took effect on August 3, 1988. Depending on the facts, the former Civil Code may treat the transaction as voidable and impose a 10-year period for the wife to bring an annulment action. Do not assume that an old transaction is governed by today’s rule merely because the dispute arose recently.

Neither spouse may donate community or conjugal property without the other’s consent, except for moderate donations for charity or occasions of family rejoicing or distress. The Family Code also generally prohibits donations between spouses during marriage, apart from moderate gifts on family occasions, and extends the prohibition to persons living together as spouses without a valid marriage.

Property rights when the partners are unmarried

There is no single property regime for every live-in relationship. The key distinction is between Articles 147 and 148 of the Family Code.

Article 147: partners legally free to marry each other

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

Its principal rules are:

wages and salaries are owned in equal shares;
property acquired through either or both partners’ work or industry is governed by co-ownership;
property acquired during the union is presumed to have resulted from joint efforts and is generally owned in equal shares unless proved otherwise; and
caring for and maintaining the family and household counts as a contribution even if that partner had no salary or outside income.

Property owned before cohabitation generally remains separate. The fruits or income of a partner’s separate property do not automatically enter the Article 147 co-ownership.

While cohabitation continues, neither partner may dispose of or encumber his or her share in the co-owned property without the other’s consent. Rules on forfeiture can apply when the union ends and one or both partners acted in bad faith, particularly where there are common children.

The Supreme Court explains this special co-ownership in Paterno v. Paterno and Valdes v. Regional Trial Court.

Article 148: relationships outside Article 147

Article 148 generally applies when the partners could not legally marry each other, such as when one partner remained validly married to another person, or when the relationship was not exclusive.

Its protection is more limited:

only property acquired through the partners’ actual joint contribution of money, property, or industry is co-owned;
ownership is proportional to the proven contributions;
equal shares are presumed only after actual joint contribution and acquisition have been established; and
household care, by itself, does not receive the same express treatment as a contribution that it receives under Article 147.

Mere cohabitation, affection, domestic assistance, or the fact that an asset was acquired while the partners lived together does not automatically establish co-ownership under Article 148. The claimant must connect an actual contribution to the acquisition of the particular property.

If one partner is validly married to somebody else, that partner’s share may accrue to the absolute community or conjugal partnership in the valid marriage. A partner who acted in bad faith may also lose his or her share under the forfeiture rules in Article 148.

The requirement of actual contribution is applied in Agapay v. Palang, Tumlos v. Fernandez, and Saguid v. Court of Appeals.

Whose name appears on the title?

Registration in one partner’s name is significant, but it is not conclusive in every dispute.

For spouses, property acquired during marriage may still be presumed community or conjugal even when the title names only one spouse. Conversely, a title issued during marriage does not prove that the property was acquired during marriage; the underlying deed and acquisition date may show that it was inherited, donated, or bought earlier.

For unmarried partners, placing both names on a title is strong evidence of the recorded interests, but Article 147 or 148 and the evidence of contribution may still matter. Placing only one name on the title can make the other partner’s claim substantially harder to prove, especially under Article 148.

Before purchasing real property together, unmarried partners should consider a properly drafted agreement stating:

each person’s contribution;
their percentage interests;
responsibility for loan payments, taxes, insurance, and improvements;
who may occupy or lease the property;
what happens upon separation, disability, or death; and
how a buyout, sale, or partition will be handled.

The agreement cannot override mandatory law, prejudice creditors, defeat the rights of a lawful spouse or compulsory heirs, or validate an otherwise unlawful transaction.

Separation does not immediately divide marital property

Physical separation alone does not dissolve a marriage or automatically terminate the existing property regime. As a general rule, spouses remain subject to that regime until it is lawfully dissolved or judicial separation of property is ordered.

Article 100 for absolute community and Article 127 for conjugal partnership address spouses who are separated in fact. A spouse who leaves without just cause generally loses the right to support, but separation does not by itself transfer ownership. Court authorization may be sought when the other spouse’s consent is required and cannot be obtained, or when abandonment and other statutory grounds justify judicial relief.

For unmarried co-owners, either partner may generally demand partition under Articles 494 to 498 of the Civil Code, subject to a valid agreement not to divide for a permitted period and to restrictions imposed by law. Partition may be voluntary if all parties agree. Otherwise, a judicial action may be necessary. If physical division would make the property unusable and no co-owner will take it with payment of the others’ shares, a sale and division of the proceeds may be ordered.

Rights after a partner dies

A surviving legal spouse has marital-property rights and may also inherit under succession law. These are separate calculations: the marital property must first be liquidated to identify the surviving spouse’s own share, after which the deceased spouse’s estate is distributed.

When a marriage ends by death and no judicial settlement is started, Article 103 or 130 of the Family Code requires the surviving spouse to liquidate the absolute community or conjugal partnership judicially or extrajudicially within one year. If liquidation is not completed within that period, dispositions or encumbrances involving property of the terminated regime are void. A subsequent marriage entered into without complying with the required liquidation rules triggers a mandatory complete-separation regime for the later marriage.

An unmarried surviving partner is not a “surviving spouse” and does not inherit merely because of long cohabitation. The partner may still:

retain a proven share as co-owner under Article 147 or 148;
receive property under a valid will, but only within the portion the deceased could legally dispose of;
collect as a valid beneficiary of insurance or similar arrangements, subject to the governing law and contract; or
assert another independently established contractual or property right.

Claims of compulsory heirs, creditors, a lawful spouse, and rules on prohibited or excessive donations may limit what the surviving partner receives. A live-in partner should not sell estate property solely on the assumption that cohabitation made him or her an heir.

Evidence worth preserving

Keep originals or secure copies of:

marriage certificates and marriage settlements;
prior marriage records, judgments, and certificates of finality or annotation;
transfer certificates of title, condominium certificates, tax declarations, deeds, and contracts to sell;
vehicle registrations and purchase documents;
bank statements, deposit slips, loan records, amortization histories, and remittance receipts;
payroll records, tax returns, business records, and proof of financial capacity;
inheritance documents, wills, deeds of donation, and estate-settlement papers;
invoices and receipts for construction, renovations, taxes, insurance, and major improvements;
messages or emails discussing ownership percentages, reimbursement, consent, or source of funds;
proof of the dates and exclusivity of cohabitation; and
evidence of childcare, household management, or family maintenance when Article 147 may apply.

Make lawful backups before access to a shared home, device, email account, or bank account is lost. Do not alter documents, forge a signature, enter a partner’s private account without authority, or remove original titles merely to gain leverage.

Practical steps when ownership is disputed

Identify the legal relationship. Confirm whether there is a valid marriage, a void or voidable marriage, or no marriage. Check for an existing prior marriage and obtain official civil-registry records where necessary.
Identify the governing regime. Review the marriage date and any registered marriage settlement. For unmarried partners, determine whether Article 147 or 148 is potentially applicable.
Create an asset-and-debt inventory. List real property, vehicles, businesses, bank accounts, investments, insurance, valuable personal property, loans, and alleged transfers.
Trace each asset. Record when it was acquired, whose name appears on the document, the source of the purchase money, and who paid later expenses.
Secure registry records. Obtain certified copies of titles and relevant annotations. If a transfer or mortgage appears imminent, legal advice is urgent; an informal objection may not protect the property.
Avoid unilateral transfers. Selling, mortgaging, donating, or withdrawing disputed assets can create additional civil, criminal, or family-law issues.
Seek a documented resolution. A written settlement, deed of partition, buyout, or sale may work if all necessary parties consent and legal formalities are satisfied.
Use the proper proceeding. Depending on the facts, the remedy may involve liquidation in a nullity, annulment, legal-separation, or estate case; judicial separation of property; partition; declaration of nullity of a conveyance; reconveyance; injunction; or another civil action.

Common mistakes

Assuming “conjugal” means every asset is automatically divided equally.
Believing that paying household expenses always creates ownership under Article 148.
Treating a tax declaration as conclusive proof of title.
Signing a waiver without an inventory, valuation, and accounting of debts.
Accepting a photocopy or social-media post as proof that a prior marriage was terminated.
Relying on oral consent to sell or mortgage community or conjugal property.
Transferring property to relatives to keep it away from a spouse, partner, creditor, or heir.
Assuming an unmarried partner automatically inherits.
Delaying action because a void transaction is thought to be challengeable forever. Remedies, limitation periods, laches, third-party rights, and procedural rules are fact-sensitive.
Filing only a title-correction petition when the real dispute requires a full civil action over ownership.

When legal help is urgent

Consult a Philippine lawyer promptly if:

a deed, mortgage, waiver, foreclosure, auction, or title transfer is pending;
a signature or special power of attorney may have been forged;
property is being hidden, withdrawn, or transferred to another person;
one partner has died and estate assets are being sold;
there is a prior marriage, foreign divorce, disputed marriage record, or allegedly void marriage;
a bank, buyer, creditor, lawful spouse, or heir is asserting competing rights;
you have received a summons, demand letter, notice of foreclosure, or registry notice; or
violence, threats, forced eviction, or financial control affects your safety.

Economic abuse—including controlling a woman’s money or property in circumstances covered by law—may fall under the Anti-Violence Against Women and Their Children Act. Protection orders and other remedies may be available. In immediate danger, contact the Philippine National Police, the barangay VAW Desk, or emergency services and prioritize physical safety over collecting documents.

Frequently asked questions

If the title is in my spouse’s name, do I have no rights?

Not necessarily. If the property was acquired during the marriage, it may be community or conjugal despite being titled in only one spouse’s name. The acquisition date, source of funds, applicable regime, and any statutory exclusion must be examined.

If I paid all the installments, do I own the entire property?

Not automatically. For married spouses, payments may have come from community or conjugal funds even if earned or remitted by only one spouse. Under Article 147, the law recognizes equal wages and household contributions. Under Article 148, proof of each partner’s actual contribution is critical.

Does living together for many years create a common-law marriage?

No. Philippine law does not convert cohabitation into a valid marriage merely because it lasted for a particular number of years. Cohabitation can nevertheless create property rights under Article 147 or 148.

Can my spouse sell our property without my signature?

If the asset is community or conjugal and the Family Code governs the transaction, disposition or encumbrance ordinarily requires your written consent or court authority. The exact remedy depends on the transaction date, documents, property classification, and whether the supposed consent is genuine.

Can an unmarried partner inherit without a will?

Not merely as a live-in partner. The survivor may retain a proven co-ownership share, but co-ownership is different from inheritance. A valid will or beneficiary designation may help, subject to compulsory heirs and other legal restrictions.

Can I demand partition while we are still living together?

Ordinary co-owners generally have a right to seek partition, but Articles 147 and 148 impose special rules, including restrictions on disposition during cohabitation and possible forfeiture upon termination. For married couples, individual marital assets ordinarily cannot be partitioned as though the spouses already owned fixed halves; the governing property regime must first be properly dissolved and liquidated.

Are household and childcare efforts enough to establish a share?

They can qualify as contribution under Article 147. Under Article 148, the law requires actual joint contribution of money, property, or industry, and the Supreme Court has distinguished this from Article 147’s express recognition of family and household care.

Can partners simply sign a document saying everything is separate?

Unmarried partners may document ownership and financial arrangements, subject to mandatory law and third-party rights. Married spouses cannot ordinarily replace their existing statutory property regime with a private post-wedding agreement; modification generally requires compliance with the Family Code and, in appropriate cases, court action.
