Introduction

In Philippine law, the phrase “common-law partner” usually refers to two people who lived together as husband and wife without a valid marriage. This can include a long-term heterosexual union, a relationship where one or both parties were legally disqualified from marrying each other, or a domestic partnership that functioned like a family unit but never became a legal marriage.

This distinction matters because Philippine law does not recognize common-law marriage as the equivalent of a valid marriage. No matter how long two people lived together, cohabitation alone does not create the legal status of husband and wife. Because of that, a surviving common-law partner does not automatically enjoy the same property and inheritance rights as a lawful spouse.

Still, a surviving common-law partner is not always without rights. Depending on the facts, Philippine law may recognize:

a share in properties acquired during cohabitation,
a right to reimbursement or return of contributions,
a co-ownership interest,
a claim under Article 147 or Article 148 of the Family Code,
a contractual or equitable claim, and
in some cases, benefits under specific statutes or institutional rules, which are different from succession rights.

The governing rules depend heavily on the nature of the relationship and on how the property was acquired.

I. No Common-Law Marriage in the Philippines

A fundamental starting point is this:

There is no common-law marriage in the Philippines.

Living together for many years does not convert a couple into lawful spouses. The legal consequences of a valid marriage arise only from a marriage celebrated in accordance with law, except in a few special cases involving marriages exempt from license requirements, which are still actual marriages, not common-law marriages.

Because there is no common-law marriage:

A surviving common-law partner is not a compulsory heir as a spouse.
A surviving common-law partner is not entitled by intestate succession to inherit as a husband or wife.
The surviving partner cannot claim the rights of a widow or widower merely on the basis of cohabitation.
Property relations are governed not by the rules on absolute community or conjugal partnership, but mainly by co-ownership rules under the Family Code and Civil Code.

This is the biggest legal divide between a lawful spouse and a common-law partner.

II. Why the Surviving Partner May Still Have Property Rights

Although a common-law partner is not treated as a spouse, Philippine law does recognize that property can be acquired during cohabitation through the efforts, work, or contributions of the partners.

The main legal provisions are:

Article 147 of the Family Code
Article 148 of the Family Code
relevant rules on co-ownership under the Civil Code
rules on succession under the Civil Code
principles on contracts, unjust enrichment, implied trust, reimbursement, and proof of actual contribution

The first task in any case is to classify the relationship.

III. Article 147 of the Family Code: Cohabitation of Parties Capacitated to Marry Each Other

A. When Article 147 applies

Article 147 applies when:

a man and a woman lived exclusively with each other as husband and wife,
without a valid marriage, and
they were capacitated to marry each other.

This usually covers couples who were both single, of legal age, and not otherwise disqualified from marriage, but who simply did not get legally married.

B. Basic property rule under Article 147

Under Article 147, the wages and salaries of each partner remain owned by that partner alone.

However, property acquired during the union through their work or industry is governed by co-ownership.

A crucial feature of Article 147 is that a party who did not directly acquire property in his or her own name may still be deemed to have contributed, including through:

care and maintenance of the home,
care of the family,
household management,
homemaking,
support of the partner’s productive efforts.

This is one of the most protective features of Philippine law for certain unmarried cohabitants. The law recognizes that contribution is not only financial.

C. Presumption of equal shares

In the absence of proof to the contrary, properties covered by Article 147 are generally presumed to be owned in equal shares.

This is significant for a surviving partner. If the deceased acquired property during the relationship and the case falls under Article 147, the survivor may claim that half already belonged to the survivor before the deceased died. The decedent’s estate would include only the decedent’s share, not the whole property.

D. What kinds of properties are covered

Article 147 generally covers property acquired during cohabitation through actual joint contribution, work, industry, or efforts. This can include:

a house built during the relationship,
land bought through pooled earnings,
vehicles acquired from business income generated during cohabitation,
business assets developed through the joint efforts of the parties,
savings accumulated through the union.

The label on the title is not always conclusive. A property titled only in the deceased partner’s name may still be proven to be co-owned if it was acquired through the parties’ joint efforts within Article 147.

E. What is not automatically covered

Not all property of the deceased becomes co-owned. For example:

property owned by the deceased before cohabitation,
property received by the deceased through inheritance or donation in a purely personal capacity,
property acquired solely with exclusive funds and not through joint efforts,
exclusively personal assets unconnected to the union,

may remain exclusive to the deceased, unless there is proof of contrary intention or subsequent contribution creating a different right.

F. Effect of death under Article 147

When one partner dies:

Determine which properties are co-owned under Article 147.
Segregate the surviving partner’s share.
Only the decedent’s share goes into the estate for settlement and succession.

This is often misunderstood. The surviving common-law partner does not inherit the whole property as a spouse, but may still own a portion outright as a co-owner.

That ownership is not succession; it is prior ownership.

IV. Article 148 of the Family Code: Cohabitation When Parties Are Not Capacitated to Marry Each Other

A. When Article 148 applies

Article 148 governs unions where the parties lived together but were not legally capacitated to marry each other. Examples include:

one or both parties were already married to someone else,
the relationship was adulterous or bigamous in character,
there was another legal impediment to marriage.

B. Property rule under Article 148

Article 148 is more restrictive than Article 147.

Only properties acquired by the parties through their actual joint contribution of money, property, or industry are co-owned, and their shares are proportionate to their actual contributions.

If there is no proof of the exact amount of each contribution, there may be a presumption of equal shares, but only with respect to the property actually proven to have been jointly acquired.

C. No presumption based on household services alone

Unlike Article 147, Article 148 does not generally give the same broad recognition to homemaking or domestic care as equivalent contribution for purposes of co-ownership.

This means a surviving partner in an Article 148 relationship usually has a harder burden of proof. He or she must show actual contribution of:

money,
labor,
property,
direct industry connected to the acquisition.

This is a major difference.

D. Effect when one party is validly married to another

If one party was legally married to someone else, special complications arise because part of the property may belong to the legal marriage’s property regime. The common-law partner cannot defeat the legitimate rights of the lawful spouse.

In practice:

the surviving common-law partner may claim only the portion traceable to his or her actual contribution,
the rest may belong to the deceased, to the conjugal or community property with the lawful spouse, or to the estate.

E. Effect of death under Article 148

Upon death, the surviving partner can claim only the proven co-owned share. Again, this is not inheritance as a spouse. It is a property claim based on actual contribution.

V. The Most Important Distinction: Ownership Rights vs. Inheritance Rights

This is the central legal point.

A surviving common-law partner may have:

ownership rights, but not necessarily
inheritance rights.

Ownership rights

These arise because the survivor already owned part of the property before the death, usually through co-ownership under Article 147 or 148.

Inheritance rights

These arise through succession after death.

A lawful spouse has both possible property regime rights and succession rights. A common-law partner may have the first, but usually not the second.

This distinction changes everything in estate disputes.

VI. Can a Surviving Common-Law Partner Inherit from the Deceased?

A. By intestate succession: generally no

If the deceased dies without a will, a surviving common-law partner is not an intestate heir as a spouse.

Under Philippine succession law, intestate heirs include, depending on who survives:

legitimate children and descendants,
legitimate parents and ascendants,
illegitimate children,
the surviving lawful spouse,
collateral relatives in default of the above,
and ultimately the State.

A common-law partner is not included merely because of cohabitation.

So if the deceased left no will, the surviving common-law partner cannot say, “I am the widow” or “I am the widower” unless there was a valid marriage.

B. By testate succession: yes, if named in a will

A common-law partner may receive property by will, subject to the rules on legitime.

The deceased may institute the surviving common-law partner as:

an heir to the free portion,
a devisee of real property,
a legatee of personal property,
a beneficiary under specific testamentary provisions.

However, the will cannot impair the legitime of compulsory heirs such as:

legitimate children,
legitimate descendants,
legitimate parents in certain cases,
illegitimate children,
surviving lawful spouse.

So a common-law partner can inherit only from the free disposable portion, unless there are no compulsory heirs or the disposition remains within lawful limits.

C. Unworthiness and void donations between certain parties

In some situations, especially where the relationship is adulterous or otherwise prohibited, dispositions in favor of the partner may face legal issues. Donations inter vivos between persons guilty of adultery or concubinage at the time of donation are void. Testamentary dispositions raise separate succession issues and must be analyzed carefully under the Civil Code and public policy limitations.

The validity of dispositions to a common-law partner can therefore depend on the nature of the relationship and the kind of transfer involved.

VII. Rights Over the Family Home or Shared House

A common-law partner often believes that long residence in the shared house creates automatic ownership. That is not always true.

Several possibilities exist:

A. The house is exclusively owned by the deceased

If the house was owned by the deceased before the relationship, inherited solely by the deceased, or bought exclusively with the deceased’s exclusive funds, the surviving partner does not become owner merely by living there.

At most, the survivor might claim:

reimbursement for proven improvements,
return of contributions,
compensation for share in construction costs,
temporary possessory relief in some circumstances pending estate settlement.

B. The house is co-owned under Article 147 or 148

If the house was acquired or built during cohabitation through joint efforts or contributions, the surviving partner may claim a share.

C. Land owned by one, house built with joint funds

This is a common source of dispute. Ownership of land and building may require separate analysis. A surviving partner may fail to own the land but still have a claim with respect to the house or improvements, depending on contribution and accession principles.

D. No automatic right to stay forever

Even if the survivor lived in the house for decades, there is no automatic lifetime right of occupancy merely from being a partner, unless:

he or she is an owner or co-owner,
there is a will granting usufruct or ownership,
there is a contract,
or another specific legal basis exists.

VIII. Bank Accounts, Vehicles, Businesses, and Personal Property

A. Bank accounts

If a bank account is solely in the deceased’s name, the surviving partner does not automatically own it. He or she must prove:

co-ownership,
actual contributions,
trust arrangement,
or a beneficiary designation if applicable.

If the account is joint, the bank contract and surrounding facts matter, but a joint account does not always settle the question of ultimate beneficial ownership.

B. Vehicles

A vehicle registered in the deceased’s name may still be shown to be co-owned if paid for through joint funds under Article 147 or 148. Registration is evidence, but not always the last word.

C. Business interests

A surviving common-law partner may claim a share in a business if it was built through joint efforts or actual capital contribution. If the business is a corporation, however, the claim must respect corporate personality. The survivor may claim rights over the deceased’s shares or over contributions, but not simply seize corporate assets.

D. Appliances, furniture, jewelry, and household assets

These may be treated as co-owned if acquired through the parties’ common efforts during cohabitation. Receipts, witnesses, bank records, and possession history become important.

IX. Can the Surviving Partner Claim Reimbursement Instead of Ownership?

Yes.

Even if the survivor cannot prove co-ownership of the property itself, he or she may still assert claims such as:

reimbursement of money used to buy or improve the property,
return of loans extended to the deceased,
compensation for materials furnished,
recovery of advances,
enforcement of a written agreement,
unjust enrichment.

For example, if the survivor paid for renovations on a house solely owned by the deceased, the survivor may not become co-owner of the land, but may claim reimbursement for proven expenses.

X. Burden of Proof: The Biggest Practical Issue

Most cases are won or lost on proof.

A surviving common-law partner should be able to show, where possible:

receipts,
bank transfers,
deeds of sale,
loan documents,
construction records,
text messages or letters acknowledging contribution,
tax declarations,
titles,
business permits,
witness testimony,
proof of homemaking and family support in Article 147 situations,
proof that both were capacitated to marry, if invoking Article 147.

Bare claims like “we lived together for 20 years” are often not enough.

The survivor must prove:

the existence and character of the union,
whether Article 147 or Article 148 applies,
which properties were acquired during cohabitation,
what contributions were made,
what share belongs to the survivor.

XI. The Difference Between Article 147 and Article 148 in Estate Disputes

This distinction cannot be overstated.

Under Article 147:

applies when both were free to marry each other,
recognizes domestic and homemaking contributions,
generally more favorable to the surviving partner,
often supports an equal-share theory absent contrary proof.

Under Article 148:

applies when there is a legal impediment,
requires proof of actual contribution of money, property, or industry,
is narrower and stricter,
protects the rights of the lawful spouse and legitimate family.

A surviving partner who assumes Article 147 applies may fail completely if the deceased was actually married to someone else.

XII. Rights Against the Legal Spouse and Legitimate Heirs

Where the deceased had a lawful spouse or legitimate family, conflict is common.

The lawful spouse may argue:

the common-law partner has no inheritance rights,
the property belongs to the marriage regime,
the common-law partner contributed nothing,
the relationship falls under Article 148, not Article 147.

The common-law partner may counter:

certain properties were acquired through the survivor’s own funds or labor,
the claimed property was never part of the lawful marriage’s regime,
the survivor is asserting ownership, not inheritance.

The court then traces titles, dates, sources of funds, and the legal status of the parties.

The common-law partner cannot rely on emotion or duration of the relationship. The claim must rest on a legal and evidentiary basis.

XIII. Succession Proceedings: What Happens When the Partner Dies

Once the deceased’s estate is under settlement, the surviving common-law partner may need to assert rights in one of several ways:

file a claim in the estate proceedings,
intervene to assert ownership over specific property,
seek exclusion of co-owned property from the estate inventory, or
file a separate civil action, depending on procedural posture.

The key objective is usually to prevent the entire property from being treated as part of the decedent’s estate when the survivor already owns a share.

For example, if a house is worth ₱4,000,000 and the survivor proves a one-half share under Article 147, only ₱2,000,000 should ordinarily belong to the estate.

XIV. Can the Surviving Partner Be an Heir Through Adoption, Acknowledgment, or Other Family Ties?

A surviving common-law partner does not become an heir through the relationship alone. But separate legal links may matter.

For example:

If the survivor is also a creditor, he or she can collect as a creditor.
If the survivor is also a co-owner, he or she can claim co-owned property.
If the survivor is also a legatee or devisee under a will, he or she may take under the will.
If the survivor has a distinct legal status unrelated to being a partner, rights may arise from that separate status.

But cohabitation by itself does not create forced heirship.

XV. Insurance, Retirement, Death Benefits, and Similar Claims

These are often confused with inheritance.

A surviving common-law partner’s right to receive proceeds from insurance or benefits depends on the governing law, policy, or institutional rules, not on marriage law alone.

A. Life insurance

If the surviving common-law partner is the designated beneficiary, the partner may receive the proceeds, subject to insurance law and any disqualification issues that may apply in particular circumstances.

This is not inheritance from the estate in the ordinary sense. Insurance proceeds may pass by beneficiary designation.

B. Employment, pension, and social legislation

Some laws or benefit systems may use their own definitions of beneficiaries or dependents. In some settings, a common-law partner may qualify; in others, not.

But these are special statutory or contractual rights, not proof that the common-law partner is a spouse for all property and succession purposes.

A person may therefore receive a benefit as a named beneficiary or qualified dependent and still have no intestate inheritance right.

XVI. Donations During Lifetime

A deceased partner may have transferred property to the common-law partner during life by donation or sale. These transfers must be examined carefully.

A. Valid sales

A genuine sale supported by consideration may be valid, provided it is not simulated or otherwise illegal.

B. Donations

Donations to a common-law partner can face legal problems, especially if the relationship fell within situations prohibited by law, such as adultery or concubinage at the time of the donation.

This means that even before death, a supposed transfer to the common-law partner may be attacked by heirs if it was legally void.

XVII. Children of the Union and Their Effect on Property Disputes

The presence of children changes the practical landscape.

If the deceased and surviving common-law partner had children together:

those children may have succession rights as illegitimate children if properly recognized or otherwise legally established,
the surviving partner still does not become a spouse-heir,
but the survivor may act in matters involving the children’s rights, depending on parental authority and procedure.

The children’s rights should not be confused with the surviving partner’s rights. A parent cannot appropriate what belongs to the children unless legally authorized.

XVIII. Foreign Elements and Same-Sex Cohabitation

A. Foreign marriages

If one partner claims there was a foreign marriage, that must be proved as a valid marriage recognized under Philippine conflict rules. If valid, the survivor may have spousal rights. If not, the relationship is treated as non-marital cohabitation.

B. Same-sex partners

As a matter of current Philippine marriage law, same-sex unions are not recognized as marriage. Property disputes between same-sex partners are therefore generally approached through ordinary co-ownership, contracts, contributions, and equitable claims rather than spousal property regimes.

The same evidentiary principles remain crucial: contribution, title, agreements, and proof.

XIX. Common Misconceptions

1. “We lived together for ten years, so I am the legal spouse.”

False. Length of cohabitation does not create a valid marriage.

2. “I am automatically entitled to half of everything.”

Not necessarily. It depends on whether Article 147 or 148 applies, what property is involved, and what was actually acquired through the union.

3. “Because the title is in the deceased’s name, I have no claim.”

Not always. A titled property can still be co-owned if the law and evidence support that conclusion.

4. “Because I took care of the home, I always get half.”

Not always. That argument is far stronger under Article 147 than under Article 148.

5. “As surviving partner, I inherit just like a widow.”

False. Without a valid marriage, there is generally no intestate spousal inheritance.

6. “If I am not an heir, I have no rights.”

False. A non-heir can still be a co-owner, creditor, beneficiary, transferee, or claimant for reimbursement.

XX. Practical Framework for Determining the Surviving Partner’s Rights

A proper legal analysis usually follows this order:

Step 1: Was there a valid marriage?

If yes, spousal property and succession rules apply.
If no, continue.

Step 2: Were the parties capacitated to marry each other?

If yes, Article 147 may apply.
If no, Article 148 may apply.

Step 3: What property is being claimed?

land,
house,
bank funds,
business,
vehicle,
personal property,
insurance,
pension benefit,
inheritance under a will,
reimbursement claim.

Step 4: When and how was it acquired?

before cohabitation,
during cohabitation,
by inheritance,
by donation,
through salaries,
through pooled resources,
through labor or business activity.

Step 5: What proof exists?

documentary proof,
witnesses,
admissions,
financial trail,
proof of household contribution,
proof of legal capacity to marry.

Step 6: Is the survivor claiming ownership or inheritance?

This determines the legal basis and remedy.

XXI. Remedies Available to the Surviving Common-Law Partner

Depending on the facts, the surviving partner may seek:

declaration of co-ownership,
partition,
reconveyance,
exclusion of property from the estate inventory,
reimbursement,
accounting,
recovery of possession,
enforcement of a contract,
recognition of rights as named beneficiary,
enforcement of rights under a will.

These remedies are fact-specific and often overlap.

XXII. Limits of the Surviving Partner’s Rights

Even where the survivor has a valid claim, the rights are limited by:

the lawful spouse’s rights,
the rights of compulsory heirs,
the classification of the relationship under Article 147 or 148,
proof of contribution,
the source of the funds used,
validity of titles and transfers,
procedural requirements in estate settlement.

The survivor cannot simply displace all heirs by invoking cohabitation.

XXIII. Key Philippine Legal Principles Summarized

No common-law marriage exists in the Philippines.
A surviving common-law partner is not automatically a spouse-heir.
The survivor generally has no intestate inheritance rights as a spouse.
The survivor may still own a share in property through co-ownership.
Article 147 applies if the parties were free to marry each other and is more protective.
Article 148 applies if they were not free to marry each other and is stricter.
Under Article 147, homemaking and care of the family may count as contribution.
Under Article 148, actual contribution of money, property, or industry must generally be proven.
The survivor may receive property through a will, subject to legitime rules.
A surviving partner may also have rights as a creditor, co-owner, beneficiary, or transferee, even without inheritance rights.

Conclusion

In the Philippines, the property rights of a surviving common-law partner are real but limited. They do not arise from marriage, because there was no valid marriage. They arise, if at all, from ownership, co-ownership, contribution, contract, beneficiary designation, or testamentary disposition.

The most important legal distinction is between:

what the surviving partner already owns, and
what the surviving partner may inherit from the deceased.

A common-law partner may successfully claim part of a house, business, savings, or other assets if those were acquired through joint efforts and fall under Article 147 or Article 148. But absent a valid marriage or a will, the survivor generally does not inherit as a spouse.

So the real question in every case is not simply, “Was this person the long-time partner of the deceased?” The real questions are:

Were they legally free to marry?
Which law applies: Article 147 or 148?
What properties were acquired during the union?
What did the survivor contribute?
Is the claim one of ownership, reimbursement, or succession?

Those questions determine whether the surviving common-law partner receives nothing, a reimbursement, a fractional share, or a substantial property interest independent of inheritance.
