A common-law partner generally does not inherit automatically when a partner dies without a will in the Philippines. No matter how long the couple lived together, whether they had children, or whether relatives treated them as husband and wife, cohabitation alone does not make the surviving partner a legal spouse or intestate heir.

That does not always mean the survivor receives nothing. The surviving partner may already own part of a house, business, savings, vehicle, or other property under the co-ownership rules in Articles 147 or 148 of the Family Code. Common children may also inherit directly from the deceased. The critical first step is therefore to separate the surviving partner’s existing ownership from the deceased partner’s inheritance estate.

Can a Common-Law Partner Inherit Without a Will?

For a Filipino decedent, the usual answer is no.

When a person dies without a valid will, legal or intestate succession applies under Articles 960 and 961 of the Civil Code. The law distributes the estate among specified relatives, the lawful surviving spouse, and, if there are no qualified heirs, the State.

The list includes:

Legitimate and illegitimate children and descendants
Parents and other ascendants in the situations provided by law
The lawful surviving spouse
Brothers, sisters, nephews, nieces, and other collateral relatives within the limits set by law
The State, when no qualified heir exists

A live-in partner is not included merely because of the relationship. Civil Code Articles 887 and 995 to 1001 protect a “widow” or “widower,” meaning a person legally married to the deceased—not an unmarried cohabiting partner. The Civil Code of the Philippines expressly identifies the people who may inherit by operation of law. (LawPhil)

The Supreme Court’s decision in Uson v. Del Rosario illustrates the distinction. The Court recognized the inheritance rights of the lawful wife rather than those of the deceased’s common-law partner. Although the case involved an older succession law, the basic distinction between a lawful spouse and a common-law partner remains important. (LawPhil)

What the surviving partner may still receive

Possible claim	Is it inheritance?	Basic requirement
The survivor’s share in co-owned property	No	Proof under Family Code Article 147 or 148
Repayment of money lent to the deceased	No	Proof of a genuine debt
Reimbursement for documented property expenses	Usually no	Receipts, bank records, contracts, or other evidence
Property personally owned by the survivor	No	Title, deed, receipt, registration, or proof of acquisition
A share as a named beneficiary of insurance or another benefit	Usually separate from inheritance	Valid designation and compliance with the governing law or contract
A share from the estate simply for being the live-in partner	Generally no	Cohabitation alone is insufficient
A share under the national law of a foreign decedent	Possibly	Foreign law must recognize the partner and be properly proved

Ownership Is Different From Inheritance

Many estate disputes begin with the mistaken assumption that everything registered in the deceased partner’s name automatically belongs entirely to the estate.

Before distributing an inheritance, the parties must first determine what the deceased actually owned. If the property was acquired through the efforts or contributions of both partners, the survivor may already be a co-owner. Only the deceased’s share enters the estate.

The applicable rule depends largely on whether the partners were legally free to marry each other.

Property Rights When Both Partners Were Free to Marry

Article 147 of the Family Code generally applies when:

The man and woman were legally capable of marrying each other;
They lived together exclusively as husband and wife; and
They were unmarried or their attempted marriage was void.

Under Article 147:

Wages and salaries earned during cohabitation are owned in equal shares.
Property acquired through the partners’ work or industry is governed by co-ownership.
Property acquired during the relationship is presumed to have resulted from joint efforts unless contrary evidence is presented.
Caring for the family and maintaining the household counts as a contribution, even when one partner had no salary.

This protection can be especially important for a partner who stayed home to raise the children while the other partner earned the family’s income. The homemaker does not necessarily lose ownership rights simply because the title or purchase documents were placed in the earning partner’s name.

The governing provisions appear in Articles 147 and 148 of the Family Code of the Philippines. (LawPhil)

Example

Ana and Roberto were both single and lived exclusively as a couple for 15 years. During that time, they acquired a house using Roberto’s salary while Ana cared for their children and managed the household.

If Article 147 applies, Ana may claim a co-ownership share even if the title names Roberto alone. If the property is ultimately determined to be owned equally:

Ana keeps her one-half share as owner.
Only Roberto’s one-half share forms part of his estate.
Roberto’s legal heirs inherit that estate share under the Civil Code.

Ana’s one-half is not something she inherited. It was already hers before Roberto died.

Property Rights When One or Both Partners Could Not Marry

Article 148 generally applies to relationships that do not qualify under Article 147, including situations where:

One partner remained validly married to another person;
Both partners had legal impediments to marry;
The relationship was adulterous or bigamous; or
The exclusivity and capacity requirements of Article 147 were absent.

Article 148 is more restrictive. Co-ownership arises only over property acquired through the partners’ actual joint contribution of money, property, or industry.

The survivor must ordinarily prove that an actual contribution was made. Household care alone does not receive the same express treatment that it receives under Article 147. The presumption of equal shares applies only after actual joint contribution has been established.

In Agapay v. Palang, the Supreme Court emphasized that proof of actual contribution is essential under Article 148. A mere romantic relationship, cohabitation, or assertion that the titled owner could not have purchased the property alone is not enough. (LawPhil)

Useful evidence may include:

Bank transfers used for the down payment
Loan statements showing who made amortization payments
Receipts for construction materials
Payroll records connected to the purchase
Joint bank-account records
Written agreements identifying ownership shares
Messages or emails acknowledging contributions
Testimony from sellers, contractors, accountants, or lenders
Proof that the survivor’s business income funded the acquisition

If one partner was validly married to someone else, Article 148 also contains special rules concerning how that partner’s co-ownership share may accrue to the property regime of the lawful marriage. This is why the lawful spouse, the children, and the common-law partner may all have competing—but legally different—claims.

Who Inherits the Deceased Partner’s Share?

Once the survivor’s ownership has been separated, the remaining share belonging to the deceased is distributed to the legal heirs.

Common children may inherit

Children of the deceased may inherit even if their parents were not married. Their rights are their own; they do not inherit through the surviving common-law partner.

Their filiation, meaning their legally recognized parent-child relationship, must be proved. Relevant evidence may include:

A PSA birth certificate identifying the deceased as parent
The deceased parent’s signature on the birth record
An affidavit of acknowledgment
A public document or handwritten private document recognizing the child
Records showing open and continuous recognition of the child
A final court judgment establishing filiation

The exact inheritance shares depend on who else survived the deceased, including legitimate children, illegitimate children, parents, a lawful spouse, or other relatives.

A lawful spouse may still inherit despite years of separation

Physical separation does not automatically terminate a marriage. A lawful spouse may retain inheritance rights even when:

The spouses had lived apart for many years;
The deceased had formed a new household;
The lawful spouse had another relationship; or
The common-law partner believed the marriage had effectively ended.

Legal separation also does not dissolve the marriage, although the spouse who gave cause for the legal separation may be disqualified from intestate succession under Article 1002 of the Civil Code.

Annulment, declaration of nullity, recognition of a foreign divorce, and other marital-status issues require careful examination of the relevant court judgments and PSA records.

Step-by-Step Process After a Common-Law Partner Dies

1. Secure the property and records

Collect and safeguard:

Titles and tax declarations
Deeds of sale
Bank statements
Loan and mortgage records
Vehicle registrations
Business records
Insurance policies
Receipts for improvements or construction
Proof of the survivor’s contributions
The deceased’s identification and tax records

Do not conceal, transfer, sell, or withdraw estate assets without authority. Possession of a title, ATM card, passbook, or vehicle does not by itself establish ownership.

2. Obtain civil-registry documents

The family will commonly need:

PSA death certificate
PSA birth certificates of the deceased’s children
PSA marriage certificates
A Certificate of No Marriage Record or Advisory on Marriages, when relevant
Court decisions affecting the deceased’s marital status
Death certificates of predeceased heirs
Adoption or acknowledgment documents, if applicable

A CENOMAR or an absence of a readily available PSA marriage record should not be treated as conclusive without checking for delayed registration, foreign marriages, Muslim marriages, or other legally recognized records.

3. Identify the applicable property regime

Determine whether Article 147 or Article 148 applies.

Ask:

Were both parties legally free to marry?
Did they live exclusively with each other?
Was either partner married to someone else?
When was each property acquired?
Who paid the price, loan, taxes, and improvements?
Was the property inherited or owned before cohabitation?
Whose name appears on the title, account, or registration?

Property inherited personally by one partner or acquired before the relationship will not ordinarily become co-owned merely because the couple later lived in it together.

4. Determine all legal heirs

Do not rely only on the people who attended the funeral or presently occupy the property. Search for:

Children from earlier relationships
A lawful spouse
Legally recognized nonmarital children
Adopted children
Surviving parents
Siblings or descendants of deceased siblings
Heirs residing abroad

Omitting an heir can invalidate or seriously complicate an extrajudicial settlement as to that person’s share.

5. Decide between extrajudicial and judicial settlement

An extrajudicial settlement under Rule 74 may generally be used when:

The deceased left no will;
The estate has no outstanding debts;
All heirs agree;
All heirs are adults, or minors are represented by duly authorized legal representatives; and
The required deed, publication, filing, and bond requirements are followed.

The deed must ordinarily be notarized and published once a week for three consecutive weeks in a newspaper of general circulation. It is then used for tax processing and registration.

A sole heir may execute an affidavit of self-adjudication. However, a common-law partner cannot truthfully claim to be the sole heir merely because the deceased’s relatives are absent, unknown, or uninterested.

The Rules of Court on settlement of estates contain the governing Rule 74 requirements. (LawPhil)

A judicial settlement before the Regional Trial Court is usually necessary or safer when:

Heirs dispute ownership or inheritance shares;
The survivor’s co-ownership claim is contested;
There are unpaid estate debts;
An heir is missing or cannot validly participate;
The validity of a marriage or filiation is disputed;
Someone has sold or transferred estate property without authority;
An administrator must be appointed; or
The estate cannot be divided by agreement.

The proper venue is generally the RTC of the province or city where the deceased resided at death. For a nonresident decedent, venue is generally based on where Philippine estate property is located.

A clean extrajudicial settlement commonly takes several months because of document collection, publication, tax clearance, and registration. Contested judicial proceedings may take several years, particularly when ownership, marriage, or filiation must be tried.

6. Process the estate tax and BIR clearance

For deaths on or after January 1, 2018, the estate tax is generally 6% of the net taxable estate under Republic Act No. 10963 or the TRAIN Law. The estate-tax return, when required, is generally due within one year from death.

The filing commonly involves:

Estate and heir TINs
BIR Form 1801
Certified death certificate
Titles and tax declarations
Settlement document or court order
Valuation records
Proof of deductions and debts
A CPA-certified statement when required
Proof of payment
Application for an electronic Certificate Authorizing Registration or eCAR

Current filing and payment rules also allow electronic or manual channels under Republic Act No. 11976. The BIR estate-tax page provides current forms and documentary checklists. (LawPhil)

Only the deceased’s ownership should be included in the estate. If a house was truly co-owned, the survivor’s established share should be separated from the taxable estate. When the title is solely in the deceased’s name, the BIR and Register of Deeds may require strong documentation or a court-approved determination before recognizing the survivor’s claimed share.

The extended estate-tax amnesty deadline ended on June 14, 2025. Estates that did not qualify or file by that deadline generally return to the ordinary estate-tax rules, including applicable interest and penalties. (BIR)

7. Transfer and register the property

After obtaining the eCAR and other clearances, the parties may need to process the transfer with:

Register of Deeds for titled real property
City or municipal assessor for tax declarations
Local treasurer for applicable transfer taxes and clearances
Land Transportation Office for vehicles
Banks and financial institutions for deposits
Corporate secretary or stock transfer agent for shares
Intellectual Property Office or other registries for specialized assets

Registration fees, publication expenses, notarial fees, local taxes, certified-copy costs, and professional charges vary according to the estate and location.

Documents Commonly Needed

Document	Purpose
PSA death certificate	Confirms the death and opens succession
Birth certificates of children	Establishes possible heirship and filiation
Marriage certificates and marital-status records	Identifies a lawful spouse or legal impediment
Titles, deeds, and tax declarations	Identifies registered property and acquisition dates
Loan and bank records	Shows payments and possible co-ownership contributions
Receipts and construction records	Supports reimbursement or ownership claims
Extrajudicial settlement or court order	Establishes the approved distribution
BIR Form 1801 and payment records	Estate-tax compliance
eCAR	Required for registration of transferred property
Special power of attorney	Allows a representative to act for a party
Apostille or consular authentication	Authenticates qualifying documents executed abroad
Certified foreign law and supporting evidence	Needed when a foreign decedent’s national law governs succession

Documents signed abroad normally require an apostille when issued or executed in a country covered by the Apostille Convention. Documents from non-participating countries may require authentication through the appropriate Philippine diplomatic or consular post. Philippine agencies may also require an English translation.

Special Rules for Foreigners

If the deceased was Filipino

Philippine succession law generally governs the order of heirs and their shares, even if the Filipino died or lived abroad. A foreign common-law partner does not become an intestate heir simply because the couple’s country of residence recognized domestic partnerships.

If the deceased was a foreign national

Article 16 of the Civil Code provides that the deceased person’s national law governs the order of succession, the amount of successional rights, and the intrinsic validity of testamentary provisions.

A foreign decedent’s national law may recognize a civil partner, domestic partner, or common-law spouse as an intestate heir. In that situation, the surviving partner may have a possible inheritance claim in the Philippines.

Foreign law must ordinarily be properly alleged and proved through admissible materials, such as authenticated legislation, official publications, or qualified expert evidence. Courts do not automatically take judicial notice of every foreign succession law. When foreign law is not properly proved, Philippine courts may apply the doctrine of processual presumption and presume that the foreign law is similar to Philippine law. Article 16 appears in the Civil Code. (LawPhil)

If Philippine land is involved

Article XII, Section 7 of the 1987 Constitution generally prohibits foreigners from acquiring private Philippine land, except through hereditary succession. (LawPhil)

The exception is narrowly applied. A foreign common-law partner cannot receive land merely through an informal family arrangement, simulated deed, or settlement falsely describing the partner as an heir. The partner must first be legally entitled to inherit under the applicable intestate law.

Condominium units, corporate shares, movable property, bank deposits, and other non-land assets involve different ownership restrictions and should be assessed separately.

Common Mistakes That Cause Estate Disputes

Treating years of cohabitation as a marriage

There is no rule that living together for five, ten, or twenty years automatically creates a valid marriage or inheritance rights.

Assuming the survivor owns half of everything

A one-half share may arise under Article 147, but the facts must satisfy that provision. Article 148 requires proof of actual contribution before co-ownership arises.

Assuming the title is always conclusive

A title is strong evidence of registered ownership, but it does not always resolve claims based on co-ownership, trust, fraud, or actual contribution. The person challenging the title still needs competent evidence.

Signing an extrajudicial settlement as an “heir”

A common-law partner should not sign as an heir unless a valid legal basis—such as the proven national law of a foreign decedent—actually grants that status. The partner may instead participate in documents that recognize, partition, or settle an independently established co-ownership claim.

Excluding children from earlier relationships

All legally recognized children must be considered. An agreement among only the common-law partner and common children cannot lawfully erase the rights of other heirs.

Transferring the whole property before determining ownership

A co-owner can generally dispose only of the co-owner’s undivided share. Under Civil Code Article 493, a purported sale of the entire co-owned property by only one owner is effective, at most, to the extent of that owner’s share. (LawPhil)

Frequently Asked Questions

Does a live-in partner inherit after ten years of living together?

No. The length of cohabitation does not make the partner a lawful spouse or intestate heir. It may, however, help establish the factual existence and duration of a cohabitation relevant to an Article 147 or 148 property claim.

We have children together. Does that allow me to inherit?

Not automatically. The children may inherit directly from their deceased parent once filiation is proved. Their inheritance rights do not create an inheritance share for the surviving partner.

The house is titled only in my deceased partner’s name. Can I claim half?

Possibly. Under Article 147, property acquired during qualifying cohabitation may be presumed jointly acquired, and household care may count as contribution. Under Article 148, actual financial, property, or industry contribution must be proved. The title remains important evidence, so documentary proof should be gathered promptly.

Can the deceased’s lawful spouse inherit even though they were separated for years?

Generally, yes. Separation in fact does not dissolve a marriage. The lawful spouse may remain an heir unless a specific legal ground for disqualification applies.

Can I execute an affidavit of self-adjudication because I was the deceased’s only companion?

No. An affidavit of self-adjudication is for a person who is legally the sole heir, not simply the person who lived with or cared for the deceased.

Can the heirs force me to leave the family home immediately?

They cannot remove anyone through force or without lawful process. However, a common-law partner has no automatic lifetime right to occupy the deceased’s property. Continued occupancy may depend on co-ownership, a lease, a usufruct, another contract, or the heirs’ consent. If the survivor is a co-owner, the heirs inherit only the deceased’s share and may seek partition rather than simply treating the survivor as a stranger.

Does being named as an insurance beneficiary solve the problem?

A valid beneficiary designation may allow the partner to receive insurance proceeds independently of the estate, but eligibility and disqualification rules still apply. Civil Code Article 2012 may invalidate an insurance designation when the beneficiary is prohibited from receiving a donation under Article 739, including certain adulterous or concubinage relationships. (LawPhil)

Can a common-law partner inherit through a will?

A partner who is legally capable of receiving may be named in a will, but compulsory heirs’ legitimes must be respected. Civil Code Articles 739 and 1028 may invalidate testamentary gifts between persons guilty of adultery or concubinage. A foreign beneficiary also cannot use a will to evade constitutional restrictions on Philippine land. (LawPhil)

What if the deceased partner was a foreigner?

The foreigner’s national succession law may govern and may recognize the surviving partner as an heir. That foreign law must be properly proved in the Philippine proceeding. Philippine procedural, tax, registration, and constitutional property rules will still apply to Philippine assets.
