Quick answer

In the Philippines, a person’s heirs acquire successional rights at the moment of death, but they inherit only the decedent’s transmissible property and rights, subject to the estate’s debts, taxes, administration expenses, marital-property liquidation, and valid provisions of a will.

A will cannot ordinarily deprive compulsory heirs of their legitime—the minimum share reserved by law. Without a valid will, the Civil Code determines who inherits and in what proportions. Before partition, multiple heirs generally own the estate in common; no heir automatically owns a particular house, lot, vehicle, or account merely because that heir possesses it.

The exact result depends on the family tree, validity of marriages, proof of filiation, adoption records, property regime, will, lifetime donations, debts, nationality of the decedent, and whether special Muslim personal law applies. The principal rules appear in the Civil Code, Republic Act No. 386, particularly Articles 774–1105.

First determine what actually belongs to the estate

Succession covers property, rights, and obligations not extinguished by death. Liability transmitted through inheritance is generally limited to the value of the inheritance.

Before calculating shares:

Identify the decedent’s exclusive property.
Liquidate the absolute community, conjugal partnership, separation-of-property regime, or any co-ownership.
Separate the surviving spouse’s or co-owner’s own share. That share is not inherited from the decedent.
Identify benefits that pass under a special law, contract, trust, insurance designation, or retirement plan instead of forming part of the hereditary estate.
Deduct valid debts, charges, taxes, and settlement expenses.
Account for lifetime donations that must be collated or reduced because they impair a compulsory heir’s legitime.

For example, if the family home was community or conjugal property, the surviving spouse may first receive a share as an owner after liquidation. The inheritance rules then apply only to the decedent’s net share. The surviving spouse does not simply receive an inheritance share out of the entire property.

The Supreme Court has also cautioned that some death benefits pass directly to qualified beneficiaries and do not form part of the estate. The governing benefit law or contract must be examined separately. See Macalinao v. Macalinao, G.R. No. 250613.

Compulsory heirs and the protected legitime

Compulsory heirs are persons for whom the law reserves a minimum share when the decedent leaves a will. They generally include:

Legitimate children and descendants, including children legitimated under the Family Code;
Legally adopted children, who are treated as legitimate children of the adopters;
In the absence of legitimate children or descendants, legitimate parents and ascendants;
The surviving legal spouse;
Illegitimate or nonmarital children whose filiation is duly established; and
In appropriate cases, the parents of a nonmarital child.

The Civil Code uses “legitimate” and “illegitimate” as legal classifications. “Nonmarital child” is used here where possible to avoid unnecessary stigma.

Brothers, sisters, nephews, nieces, cousins, and other collateral relatives may be intestate heirs, but they are not ordinarily compulsory heirs. They therefore have no reserved legitime merely because they are relatives.

Basic legitime rules when there is a will

The following are starting rules, not substitutes for a full computation:

Heirs who survive	Basic reserved shares
Legitimate or adopted children	Collectively, one-half of the net hereditary estate, generally divided equally among those inheriting in their own right
One legitimate or adopted child plus surviving spouse	Child: one-half; spouse: one-fourth
Two or more legitimate or adopted children plus surviving spouse	Children collectively receive one-half; spouse receives a legitime equal to that of each child
Legitimate or adopted children plus nonmarital children	Each nonmarital child’s legitime is one-half of each legitimate child’s legitime, subject to the disposable portion and the spouse’s prior legitime
Legitimate parents or ascendants, with no legitimate descendants	Collectively, one-half
Legitimate parents or ascendants plus surviving spouse	Ascendants: one-half; spouse: one-fourth
Nonmarital children only	Collectively, one-half
Nonmarital children plus surviving spouse, with no legitimate descendants or ascendants	Nonmarital children: one-third; spouse: one-third
Legitimate ascendants plus nonmarital children	Ascendants: one-half; nonmarital children: one-fourth
Legitimate ascendants, surviving spouse, and nonmarital children	Ascendants: one-half; nonmarital children: one-fourth; spouse: one-eighth
Surviving spouse alone	Generally one-half, subject to the special rule for certain marriages celebrated in imminent danger of death

The remaining disposable portion may be given to any qualified person through a valid will. When several classes concur, especially a spouse, legitimate children, and nonmarital children, the computation must ensure that the disposable portion is not exceeded.

The Family Code provides that each nonmarital child’s legitime is one-half of the legitime of a legitimate child. This supersedes the Civil Code’s older distinctions among categories of illegitimate children.

Who inherits when there is no will?

Intestate succession applies when there is no valid will, the will does not cover the entire estate, an instituted heir cannot inherit, or another circumstance under Article 960 of the Civil Code leaves property undisposed of.

Common intestate combinations include:

Surviving relatives	General intestate division
Legitimate or adopted children only	Entire estate, equally
Legitimate or adopted children plus surviving spouse	Spouse receives the same share as one child
Legitimate and nonmarital children, no spouse	Use a 2:1 ratio: each legitimate child receives twice the share of each nonmarital child
Legitimate children, nonmarital children, and surviving spouse	Spouse and each legitimate child receive two units; each nonmarital child receives one unit
Legitimate parents or ascendants only, with no descendants	Entire estate
Legitimate parents or ascendants plus surviving spouse	One-half to the ascendants; one-half to the spouse
Legitimate ascendants plus nonmarital children, no spouse	One-half to each class
Legitimate ascendants, nonmarital children, and spouse	One-half to ascendants; one-fourth to nonmarital children; one-fourth to spouse
Nonmarital children only	Entire estate
Nonmarital children plus surviving spouse	One-half to the children; one-half to the spouse
Surviving spouse only, with no descendants, ascendants, nonmarital children, siblings, nephews, or nieces	Entire estate
Surviving spouse plus brothers, sisters, nephews, or nieces	One-half to spouse; one-half to the siblings or their qualifying children
Brothers and sisters only	Full-blood siblings share equally; when full- and half-blood siblings concur, each full-blood sibling receives twice a half-blood sibling’s share
More distant collateral relatives	The nearest qualified collateral relatives may inherit, but intestate succession does not extend beyond the fifth degree
No qualified heir	The State inherits under the Civil Code and Rules of Court

These proportions apply to the net hereditary estate, not automatically to every individual asset. The heirs may agree that one receives a house while others receive cash or other property, provided everyone ultimately receives the correct value and compulsory shares remain protected.

Children, grandchildren, and proof of filiation

Legitimate and nonmarital children

Both legitimate and nonmarital children are compulsory heirs of their own parents. The principal difference is the size of the share: under Article 176 of the Family Code, a nonmarital child’s legitime is one-half of a legitimate child’s legitime.

A nonmarital child must establish filiation. Depending on the facts, relevant evidence may include:

A civil-registry birth record or final judgment;
An admission of filiation in a public document;
A private handwritten instrument signed by the parent;
Open and continuous possession of the status of a child;
Other evidence allowed by the Rules of Court and special laws; or
DNA or kinship evidence when legally and scientifically appropriate.

The applicable filing period can depend on the type of evidence, the child’s and alleged parent’s dates of birth and death, and whether rights vested before the Family Code. A possible filiation claim should be reviewed urgently because Article 175 imposes significant timing restrictions in some situations.

Grandchildren and representation

A child normally inherits in that child’s own right. A grandchild may inherit by representation, taking the place and share of a parent who predeceased the decedent or could not inherit in circumstances recognized by law. Division among representatives is by family branch, or per stirpes.

Representation does not generally arise when an heir merely renounces an inheritance. The descendants of a validly disinherited child may, however, preserve compulsory rights to the legitime under Article 923.

In Aquino v. Aquino, G.R. Nos. 208912 and 209018, the Supreme Court held that a nonmarital child may represent a deceased parent in the estate of a grandparent or other direct ascendant, regardless of the child’s birth status, subject to proof of filiation and the other requirements for representation. The Court expressly limited that ruling to representation in the direct line and did not decide intestate succession in one’s own right from collateral relatives.

Article 992’s remaining restriction involving reciprocal intestate succession between nonmarital children and the legitimate children or collateral relatives of their parents therefore requires careful application after Aquino.

Adopted children

Under Sections 41–43 of the Domestic Administrative Adoption and Alternative Child Care Act, Republic Act No. 11642, an adoptee is considered the legitimate child of the adopter. Adopters and adoptees have reciprocal testate and intestate succession rights without distinction from legitimate filiation. The filiation extends to specified members of the adoptive family.

Adoption generally severs legal ties with biological parents, except in situations recognized by the statute, such as certain stepparent adoptions. Older adoption decrees and rescissions may require examination of the law in force and the terms of the decree.

A child conceived before death

A child already conceived when the decedent died may inherit if later born under the conditions prescribed by law. Distribution should not defeat that child’s potential share.

Rights of the surviving spouse and live-in partner

A surviving spouse generally means the spouse in a legally valid and subsisting marriage. Separation in fact alone does not automatically end the marital status or inheritance rights. In a judicial legal separation, however, a spouse who gave cause for the separation is disqualified from the intestate rights specified by the Civil Code. The judgment and its factual basis must be checked.

A spouse in a void bigamous marriage is not the legal surviving spouse, even if that person entered the union in good faith. Property or reimbursement claims may nevertheless exist independently of inheritance.

A live-in partner does not become a compulsory or intestate heir merely through cohabitation. The partner may still have:

A co-ownership claim under Articles 147 or 148 of the Family Code;
Ownership based on title or proven contribution;
A valid legacy or devise from the disposable portion of a will; or
Rights as a designated beneficiary under a contract or special law.

Property rights based on co-ownership must be separated from inheritance. This distinction also applies to same-sex cohabitants whose proven property contributions may create co-ownership under Article 148, as recognized by the Supreme Court in Josef v. Ursua, G.R. No. 267469.

A will cannot freely erase compulsory heirs

A testator may control the disposable portion but cannot ordinarily take away a compulsory heir’s legitime.

Disinheritance

Valid disinheritance requires all of the following:

It is made in a will.
The will identifies the legal cause.
The cause is one expressly authorized by Articles 919–921 of the Civil Code.
If the disinherited heir denies the cause, the other heirs prove it.

Mere estrangement, parental anger, personal disappointment, or a general statement that a child “will receive nothing” is not enough unless the facts satisfy a statutory cause and the formal requirements. Reconciliation can remove the right to disinherit and render an earlier disinheritance ineffective.

Unworthiness

Unworthiness to inherit is distinct from disinheritance. Article 1032 lists serious acts that may make a person incapable of succeeding, such as specified crimes or interference with a will. It should not be alleged casually; the statutory elements and evidence must be established.

Omission and preterition

Complete omission of a compulsory heir in the direct line may constitute preterition and annul the institution of heirs, while valid legacies and devises may remain effective to the extent they do not impair legitimes. Not every omission has the same effect. An heir who was mentioned, received something, was validly disinherited, or is not in the direct line may fall under a different rule.

Excessive wills and lifetime donations

A compulsory heir who receives less than the proper legitime may demand completion of the share. Testamentary gifts and lifetime donations that exceed the disposable portion may be reduced. Donations to children are commonly charged against their legitimes through collation unless a legally effective exception applies.

A compromise or renunciation concerning a future legitime while the person who will leave the estate is still alive is void under Article 905.

Rights before and after partition

Successional rights arise at death, but settlement is still necessary. When there are several heirs, the entire estate is generally owned in common before partition and remains subject to debts.

This means:

An heir cannot appropriate a particular property merely by taking possession.
One heir cannot validly sell the entire property as sole owner without authority from the other co-owners or the court.
Income, rent, and produce from estate property must be accounted for.
Necessary preservation expenses should be documented.
Every co-heir generally has the right to demand partition.
A buyer from one heir may acquire only that heir’s transferable hereditary interest or undivided share, not the shares of the other heirs.

If an heir sells hereditary rights to a stranger before partition, the other co-heirs may have a one-month statutory right to be substituted for the buyer after receiving written notice of the sale. Immediate advice is important because the period is short.

How an estate is settled

If there is a will

A will does not transfer property by itself. It must be proved and allowed in the proper court.

A person holding the will must deliver it to the court or named executor within 20 days after learning of the testator’s death. A named executor generally has the same 20-day period to present the will and state whether the appointment is accepted. See Rules 75 and 76 of the Rules of Court.

The original will should not be marked, stapled, altered, or casually photocopied in a way that risks damage. Preserve the envelope, handwriting samples, drafts, communications, and information about witnesses and the notary.

Extrajudicial settlement

Under Rule 74, an extrajudicial settlement may generally be used when:

The decedent left no will;
The estate has no outstanding debts;
All heirs participate;
All heirs are adults, or minors and incapacitated heirs are represented by duly authorized legal or judicial representatives; and
The heirs can agree on the division.

The settlement must be in a public instrument. A sole heir may use an affidavit of self-adjudication. The settlement must be published in a newspaper of general circulation once a week for three consecutive weeks, filed where required, and accompanied by the Rule 74 bond covering personal property.

Publication does not cure the omission of an heir. An extrajudicial settlement is not binding on a person who did not participate and had no notice.

Rule 74 provides a two-year period after distribution during which specified claims may be enforced against the bond or estate property. A person who is a minor, mentally incapacitated, imprisoned, or outside the Philippines when that period expires may have an additional year after the disability is removed. These provisions are not a universal limitation period for every action involving an omitted heir, fraud, co-ownership, or reconveyance. Do not wait for the two years to expire before seeking advice.

Judicial settlement

Court proceedings are usually needed when:

There is a will;
Heirs dispute identity, shares, ownership, or partition;
A compulsory heir was omitted;
Filiation or marriage validity is contested;
Debts or creditors require administration;
An heir is missing;
A representative cannot validly act for a minor;
Property was concealed, sold, or transferred without authority; or
The heirs cannot agree.

Under Republic Act No. 11576, first-level courts generally have probate jurisdiction when the gross estate does not exceed ₱2,000,000, while the Regional Trial Court generally has jurisdiction when it exceeds that amount. This ₱2,000,000 jurisdictional threshold should not be confused with Rule 74’s separate judicial summary-settlement provision, whose unchanged statutory ceiling is only ₱10,000.

Venue ordinarily depends on the decedent’s residence at death; if the decedent lived abroad, it may depend on where Philippine estate property is located.

Estate tax and transfer requirements

Inheritance rights and estate-tax compliance are related but separate matters.

For deaths on or after January 1, 2018, the regular estate tax is generally 6% of the net taxable estate. The law in force at the time of death governs older estates unless a valid amnesty applies.

Under BIR Revenue Regulations No. 12-2018:

The estate-tax return is generally due within one year from death.
A filing extension of no more than 30 days may be granted in meritorious cases.
A return is required for taxable transfers and, regardless of gross value, when the estate includes registered or registrable property requiring a BIR clearance or eCAR.
A CPA-certified statement is required when the gross estate exceeds ₱5,000,000.
An approved payment extension may be granted for up to five years for a judicially settled estate or two years for an extrajudicially settled estate when immediate payment would cause undue hardship.
If available estate cash is insufficient, an approved installment arrangement may be allowed within two years from the statutory payment date under the governing rules.

The estate normally secures its TIN, files the return, pays the tax or obtains an approved payment arrangement, and applies for an electronic Certificate Authorizing Registration or eCAR before registered assets are transferred. Consult the BIR estate-tax page and the RDO with jurisdiction because documentary and filing-channel requirements may change.

The estate-tax amnesty under Republic Act No. 11956 is closed to new availments; its statutory period ended on June 14, 2025. For estates that timely availed, BIR RMC No. 33-2026 states that there is no deadline for submitting proof of estate settlement, but that proof remains necessary for processing and issuing the eCAR.

Evidence heirs should preserve

Keep originals secure and make organized copies of:

PSA death, birth, and marriage certificates;
Adoption orders and amended civil-registry records;
The original will and its envelope;
Titles, tax declarations, deeds, surveys, and condominium records;
Vehicle registrations and corporate share certificates;
Bank, investment, insurance, pension, and loan records;
Marriage settlements and property agreements;
Receipts proving purchase price, construction costs, loan payments, taxes, and repairs;
Records of rents, harvests, business income, or withdrawals after death;
Promissory notes, mortgages, creditor demands, and proof of payment;
Deeds and records of lifetime donations or advances;
Documents or communications acknowledging filiation;
Proof of actual contributions to property acquired during cohabitation;
Prior extrajudicial settlements, affidavits of self-adjudication, publications, eCARs, and transferred titles; and
Messages, notices, and acknowledgments showing when an heir learned of a sale or settlement.

Prepare an inventory showing each asset’s owner, acquisition date, value at death, title status, encumbrances, income, and current possessor. Do not alter originals or rely solely on photographs stored on one phone.

Common mistakes to avoid

Dividing the whole family property without first identifying the surviving spouse’s or co-owner’s share;
Treating possession of a title or residence as exclusive ownership;
Omitting a nonmarital, adopted, posthumous, or previously unknown child;
Assuming a live-in partner is automatically a spouse or heir;
Using an affidavit of self-adjudication when more than one heir exists;
Executing an extrajudicial settlement without every heir;
Believing newspaper publication cures a missing heir;
Selling estate property before authority, accounting, and settlement are clear;
Distributing assets before checking debts and taxes;
Withdrawing or concealing money without recording it;
Relying on a notarized document as proof that a will is valid without probate;
Treating an unsigned or incomplete birth record as conclusive proof of paternity;
Assuming the estate-tax amnesty remains open;
Signing a waiver without understanding whether it is a repudiation, donation, sale, or taxable transfer; and
Waiting because the family has made an informal promise to “fix the shares later.”

When legal help is urgent

Consult a Philippine succession lawyer promptly when:

A will may be hidden, destroyed, altered, or withheld;
The 20-day period for delivering a will is running;
An heir has been excluded from a settlement;
Estate property is being sold, mortgaged, occupied exclusively, or transferred;
Someone received written notice that a co-heir sold hereditary rights;
Filiation must still be established;
A marriage, adoption, or foreign divorce affects heirship;
A minor or incapacitated heir is involved;
The estate has significant debts, tax arrears, businesses, or foreign assets;
There are conflicting titles or allegations of forged signatures;
An executor or administrator is not accounting for assets or income; or
A filing, tax, or prescriptive period may be close.

Qualified indigent parties may ask the Public Attorney’s Office whether assistance is available. Courts and Integrated Bar of the Philippines legal-aid programs may also have applicable eligibility requirements.

Special rules for Muslims and foreign nationals

The foregoing discussion primarily addresses estates governed by the Civil Code.

The succession of Filipino Muslims may instead be governed by the Code of Muslim Personal Laws, Presidential Decree No. 1083, which has its own heirs, fixed shares, exclusions, and settlement rules.

For a foreign national, Article 16 of the Civil Code generally makes the decedent’s national law govern the order of succession, amount of successional rights, and intrinsic validity of testamentary provisions, regardless of where the property is located. Philippine procedural, tax, property-registration, and conflict-of-laws rules may still apply. Cross-border estates require individual analysis.

Frequently asked questions

Can a parent leave everything to only one child?

Usually not if other compulsory heirs survive. The favored child may receive that child’s legitime plus part or all of the disposable portion, but dispositions impairing other legitimes may be reduced.

Do children from different marriages inherit equally?

Legitimate or legally adopted children inheriting in their own right generally share equally, regardless of sex, age, or which marriage they came from. A nonmarital child generally receives half the corresponding share of a legitimate child under the applicable legitime or intestate formula.

Can a live-in partner inherit?

Not automatically through cohabitation. The partner may own a proven co-ownership share, receive property from the disposable portion of a valid will, or qualify under a contract or special benefit law.

Does the eldest child receive a larger share?

No. Birth order ordinarily does not increase an heir’s share.

Can an heir waive an inheritance?

After death, an heir may repudiate the inheritance through a public or authentic instrument or a petition in the estate proceeding. Repudiation is generally irrevocable. A parent or guardian needs judicial authorization to repudiate a minor’s inheritance. A waiver directed in favor of selected heirs may legally operate as an acceptance followed by a transfer, with different tax consequences.

Are heirs personally responsible for all the decedent’s debts?

Not merely because they are heirs. Succession transmits obligations only to the extent of the inheritance’s value, although an heir’s own acts, contracts, premature distributions, or misuse of estate property may create separate liability.

Is an extrajudicial settlement valid without one heir’s signature?

It does not bind an heir who did not participate and had no notice. Omission can also expose the parties and later transferees to litigation, contribution claims, reconveyance issues, and title annotations.

Is estate tax the same as the heirs’ shares?

No. Estate tax is imposed on the transfer of the net taxable estate. Civil-law shares determine how the remaining distributable estate belongs among the heirs.

Is there one deadline for claiming an inheritance?

No. Different periods govern wills, taxes, Rule 74 claims, filiation, incapacity, rescission, reconveyance, and other remedies. The Rule 74 two-year period is not a universal deadline for every inheritance dispute.
