Quick answer

Under Philippine law, an heir’s rights depend on four questions: Who died, was there a valid will, who survived the deceased, and what property actually belongs to the estate?

Certain close family members are compulsory heirs. They generally cannot be deprived of their minimum legal share, called the legitime, merely because a will leaves everything to someone else. If there is no valid will—or the will does not dispose of the entire estate—the rules on legal or intestate succession determine who inherits.

Being named in a birth certificate, living with the deceased, paying funeral expenses, possessing the property, or being the “favorite” child does not by itself settle inheritance rights. Filiation, marriage, adoption, property ownership, debts, prior donations, the will’s validity, and the complete list of heirs must all be verified.

When inheritance rights begin

Successional rights are transmitted from the moment of death. This does not mean that an heir immediately owns a particular house, vehicle, bank account, or parcel of land. Until the estate is properly settled and partitioned, the heirs ordinarily hold hereditary rights in the estate as a whole, subject to:

Liquidation of the spouses’ property regime;
Payment of enforceable debts, taxes, and administration expenses;
Compliance with a valid will;
Protection of each compulsory heir’s legitime; and
A valid partition or court-approved distribution.

A surviving spouse’s own share in community or conjugal property is separated first. Only the deceased spouse’s share, together with the deceased’s exclusive property, enters the hereditary estate.

Who are compulsory heirs?

Article 887 of the Civil Code identifies the principal compulsory heirs:

Legitimate children and descendants, with respect to their legitimate parents and ascendants;
In their absence, legitimate parents and ascendants;
The surviving spouse;
Children legally classified as illegitimate; and
In appropriate cases, the parents of an illegitimate child.

These heirs do not always inherit in the same proportion, and some classes exclude or concur with others. The exact share depends on the family combination.

An adopted child is generally treated as the legitimate child of the adopter for legal and intestate succession. Adoption must be legally established; informal care, guardianship, or foster placement does not create the same compulsory succession rights. Current domestic adoption is governed principally by the Domestic Administrative Adoption and Alternative Child Care Act.

What is a legitime?

The legitime is the portion of the estate that the testator cannot freely give away because the law reserves it for compulsory heirs.

Common starting rules include:

Family situation	General legitime rule
Legitimate children or descendants	Collectively entitled to one-half of the hereditary estate
Legitimate parents or ascendants, when no legitimate descendants survive	Generally entitled collectively to one-half
Surviving spouse with legitimate children	Generally receives a share equal to that of one legitimate child
Each illegitimate child concurring with legitimate children	Generally receives one-half of the share of a legitimate child, subject to the estate’s available portion
Surviving spouse alone	Generally entitled to one-half
Illegitimate children without legitimate descendants	Generally entitled collectively to one-half

These are not a complete computation table. The result may change when a spouse, legitimate parents, legitimate children, illegitimate children, represented descendants, adopted children, or beneficiaries under a will concur. Prior donations may also have to be added back notionally through collation to determine whether a legitime was impaired.

The controlling provisions are Articles 886 to 914 of the Civil Code.

If there is a will

A will does not automatically eliminate the rights of compulsory heirs. It must first be allowed in probate; even a notarized will cannot pass property as a will unless the proper court recognizes it.

A valid will may:

Designate heirs;
Give specific real property through a devise;
Give specific personal property through a legacy;
Divide the estate;
Impose lawful conditions; and
Dispose of the free portion remaining after all legitimes are protected.

A compulsory heir who receives less than the required legitime may demand completion of that share. Gifts, devises, or legacies that exceed the disposable portion may be reduced.

A person who possesses the deceased’s will must deliver it to the proper court within 20 days after learning of the death, under Rule 75 of the Rules of Court. Concealing, destroying, or refusing to produce a will can lead to serious legal consequences.

Preterition is different from receiving too little

Preterition occurs when a compulsory heir in the direct line is totally omitted from the inheritance without being expressly disinherited and without having received anything by will or, under the governing rules, by gratuitous title.

Its effect can be more significant than merely reducing an excessive disposition: preterition may annul the institution of heirs, while valid devises and legacies remain effective insofar as they are not otherwise excessive.

By contrast, if an heir was included but received less than the legitime, the usual remedy is completion of the deficient legitime. The language of the will and any lifetime donations must be examined before characterizing the omission.

Can a parent disinherit a child?

Only through a valid will, for a cause expressly recognized by law.

For children and descendants, Article 919 includes narrowly defined causes such as certain attempts against the testator’s life, specified accusations of crime, unjustified refusal of support, maltreatment, and leading a dishonorable or disgraceful life. The precise statutory elements matter.

A valid disinheritance requires:

A legally sufficient will;
Express identification of the disinherited heir;
A specific legal cause stated in the will; and
Proof of that cause if the heir denies it.

“I no longer speak to my child,” “my child moved abroad,” or “my child did not visit often” is not automatically a lawful ground. If the cause is absent, untrue, or not one provided by law, the disinheritance may be ineffective to the extent that it harms the heir’s legitime. Reconciliation may also deprive the testator of the right to disinherit for the reconciled conduct.

Separate rules on incapacity or unworthiness to succeed may apply to particularly serious conduct listed in the Civil Code. These should not be assumed without examining the statutory ground, evidence, and any pardon or reconciliation.

If there is no valid will

Legal or intestate succession applies when, among other circumstances:

The deceased left no will;
The will is void or was not validly executed;
The will does not dispose of the entire estate;
An instituted heir cannot or will not inherit and no applicable substitute, representation, or accretion resolves the share; or
The institution of heirs is ineffective.

The general order favors descendants, then qualifying ascendants, with the surviving spouse and illegitimate children inheriting in the combinations established by law. If none of the nearer heirs exists, collateral relatives may inherit, generally only within the fifth degree. Ultimately, an estate without qualified heirs passes to the State.

The sequence is not a simple “first name on the list takes everything.” A surviving spouse and children frequently inherit together, and both legitimate and illegitimate children may have rights in the same parent’s estate.

Rights of children born outside marriage

A child legally classified as illegitimate is a compulsory heir of each parent whose filiation is established. Under Article 176 of the Family Code, as amended by Republic Act No. 9255, the child’s legitime is generally one-half of the legitime of a legitimate child.

That rule does not mean the child automatically receives exactly half of whatever a particular legitimate sibling receives. Other heirs, the number of children, the free portion, prior donations, and whether succession is testate or intestate must be considered.

Filiation may be proved through the civil registry record, a final judgment, an admission in a public document or private handwritten instrument, or other evidence allowed by the Family Code and jurisprudence. Some actions concerning filiation have strict rules on who may sue and when. Do not wait until land has been sold or the estate distributed before obtaining advice.

Grandchildren and Article 992

Older descriptions of Article 992 often present an absolute “iron curtain” between legitimate and illegitimate family lines. That is no longer a safe summary.

In Aquino v. Aquino, the Supreme Court construed Article 992 so that grandchildren may inherit from a direct ascendant, such as a grandparent, by representing their parent regardless of the circumstances of their birth, when the requirements of representation are present. The ruling does not erase every statutory restriction involving collateral relatives. Direct-line and collateral claims must therefore be analyzed separately. See the official Supreme Court decision in G.R. No. 208912, December 7, 2021 and its subsequent application in G.R. No. 180802, August 1, 2022.

When grandchildren inherit by representation

Representation allows a qualified descendant to take the place of a person through whom that descendant claims.

It commonly arises when a child of the deceased:

Died before the deceased;
Is legally incapacitated or unworthy to inherit; or
Was validly disinherited, subject to the rights the law preserves for that child’s descendants.

Representation in the direct descending line is recognized, but it is not ordinarily triggered simply because a living child renounces the inheritance. Grandchildren who represent their parent divide the share that the represented parent would have received.

The family tree, sequence of deaths, legitimacy or adoption records, and legal reason for the parent’s non-participation must all be established.

Rights of the surviving spouse

A legally married surviving spouse is generally a compulsory heir. Before inheritance shares are calculated, the spouses’ absolute community, conjugal partnership, or other applicable property regime must be liquidated.

A spouse may lose intestate rights in circumstances expressly provided by law, such as when the spouse gave cause for a decree of legal separation. A marriage that was void, or a purported marriage that never legally existed, can produce a different result.

A long-term partner, fiancé, boyfriend, girlfriend, or common-law partner is not automatically a “surviving spouse” for succession. That person may nevertheless have independent ownership or co-ownership claims over property acquired through actual contributions or under applicable Family Code provisions. Those property claims are distinct from inheritance.

Adopted, stepchildren, and foster children

A legally adopted child generally has the status and succession rights of a legitimate child of the adopter.

A stepchild does not become a compulsory heir of a stepparent merely because the families lived together or the stepparent provided support. The stepchild may inherit if:

Legally adopted;
Validly named in a will, within the disposable portion; or
Independently entitled through another legal relationship.

Foster care does not by itself create mandatory succession rights. Republic Act No. 10165 expressly distinguishes long-term foster placement from adoption.

Brothers, sisters, nephews, nieces, and other relatives

Collateral relatives are not compulsory heirs merely because they are close to the deceased.

They may inherit by intestacy when the deceased left no qualifying descendants, ascendants, illegitimate children, or surviving spouse entitled to exclude or concur with them under the applicable provisions. Brothers and sisters of the full blood and half blood can receive different shares. Nephews and nieces may sometimes represent a deceased sibling of the decedent when they concur with surviving siblings.

Cousins and more distant relatives must establish the legally relevant degree of relationship. Intestate succession among collateral relatives ordinarily does not extend beyond the fifth degree.

Property that may not belong entirely to the estate

Before dividing anything, verify ownership. Frequently disputed assets include:

Land titled only in the deceased’s name but acquired during marriage;
Land inherited by the deceased before or during marriage;
Property paid for jointly but titled in one person’s name;
Bank accounts held jointly or “in trust”;
Corporate shares and partnership interests;
Insurance, retirement, SSS, GSIS, or employment benefits with designated beneficiaries;
Properties already donated or sold;
Property held merely as trustee, agent, or nominee; and
Assets subject to mortgage, levy, litigation, or adverse claims.

A title is strong evidence, but it may not answer every question about the spouses’ property regime, trust, fraud, simulation, or actual ownership. Likewise, a beneficiary designation may be governed by a special law or contract rather than ordinary estate distribution.

Prior gifts can affect the heirs’ shares

Lifetime donations to compulsory heirs may have to be brought into the computation through collation. Donations that exceed what the donor could legally give may be reduced after death if they impair another compulsory heir’s legitime.

Preserve deeds of donation, tax declarations, transfer records, bank evidence, and proof of whether the deceased intended the gift to be charged against the heir’s share. Calling a transfer a “sale” does not make it one if there was no genuine price or payment, but simulation must be proved.

How an estate is settled

Extrajudicial settlement

Under Rule 74, heirs may generally settle an estate without appointing an administrator when:

The deceased left no will;
The estate has no outstanding debts;
All heirs are of legal age, or minors are properly represented by authorized judicial or legal representatives; and
All participating heirs can validly agree.

The settlement must be in a public instrument and comply with filing, publication, bond, tax, and registration requirements. A sole heir may use an affidavit of self-adjudication when legally appropriate.

Publication alone does not make an omitted heir a party. Rule 74 expressly states that an extrajudicial settlement is not binding on a person who did not participate or had no notice. The two-year provision in Rule 74 protects certain claims against distributees and the bond; the Supreme Court has cautioned that it is not automatically a universal statute of limitations for every omitted-heir, fraud, reconveyance, or ownership claim.

The full rule appears in the Rules of Court on Special Proceedings. The Supreme Court discusses its requirements in Heirs of Bandoy v. Court of Appeals, G.R. No. 255258, October 19, 2022.

Judicial settlement

Court proceedings are normally appropriate when:

A will must be probated;
Heirs or creditors dispute the settlement;
An heir is missing or was omitted;
Debts remain unresolved;
The validity of a marriage, filiation, adoption, donation, deed, or title is contested;
A minor or incapacitated heir is not adequately represented;
Property must be recovered from another person;
An executor or administrator is needed; or
The heirs cannot agree on partition.

The proper venue generally depends on the deceased’s residence at death; special rules apply to nonresidents.

Estate tax and registration are separate from heirship

A deed signed by the heirs does not by itself complete the tax and transfer process. Estate-tax compliance and issuance of the required BIR clearance or electronic Certificate Authorizing Registration are ordinarily necessary before registrable property can be transferred.

For deaths governed by the current Tax Code, the estate-tax return is generally due within one year from death, subject to statutory extensions or installment arrangements when properly granted. The rules applicable to valuation, deductions, rates, amnesty, and documentary requirements depend significantly on the date of death.

Use the BIR’s current Estate Tax guidance and eCAR service requirements. Do not rely on an old checklist or assume that a previous estate-tax amnesty remains open.

Practical steps for heirs

Secure the death certificate. Obtain PSA and local civil-registry copies if needed.
Locate the original will. Check the deceased’s files, lawyer, bank safekeeping arrangements, and trusted family members. Do not alter, detach pages from, or annotate it.
Build the complete family tree. Include all marriages, children, adopted children, children born outside marriage, deceased children and their descendants, parents, and potentially relevant siblings.
Collect civil-status records. Obtain birth, marriage, death, adoption, legitimation, annulment, nullity, and legal-separation records.
Inventory assets and obligations. List land, condominium units, vehicles, bank accounts, investments, businesses, receivables, insurance, pensions, loans, mortgages, taxes, and pending cases.
Determine the spouses’ property regime. Locate the marriage certificate, marriage settlements, property acquisition dates, deeds, titles, and proof of payment.
Preserve prior-transfer records. Gather deeds of donation or sale, canceled checks, bank statements, tax records, acknowledgments, and communications explaining the transfer.
Notify and identify all heirs. Do not prepare a self-adjudication or extrajudicial settlement while knowingly omitting another possible heir.
Obtain current BIR and Registry of Deeds requirements. Requirements vary with the assets, date of death, and place of registration.
Use a written accounting. Record rent, harvest income, dividends, withdrawals, repairs, taxes, and expenses collected or paid after death.
Have the shares computed before signing. A waiver, sale, partition, or settlement may have tax and ownership consequences that are difficult to reverse.
Register completed transfers. Settlement among heirs and transfer on the title, tax declaration, corporate books, or vehicle registration are separate steps.

Evidence worth preserving

Keep originals or authenticated copies of:

Birth, marriage, and death certificates;
Adoption or legitimation orders and annotations;
The original will and any codicil;
Land titles, tax declarations, surveys, and acquisition deeds;
Marriage settlements and property agreements;
Bank, investment, insurance, SSS, GSIS, and employment records;
Corporate stock certificates and business records;
Loan, mortgage, and creditor documents;
Deeds of donation, sale, waiver, partition, or self-adjudication;
Proof of consideration and payment;
Tax returns, receipts, eCARs, and registration records;
Messages or letters containing admissions of filiation or ownership;
Rental, harvest, dividend, and expense records; and
Copies of publications, notices, pleadings, and court orders.

Create secure digital copies, but preserve originals. Avoid surrendering an original title, will, or civil-registry document without a receipt and a clear legal purpose.

Common mistakes

Dividing the deceased’s gross property without first separating the surviving spouse’s own share;
Assuming the eldest child controls the estate;
Treating possession of land as proof of exclusive ownership;
Excluding a child born outside marriage without examining filiation and current jurisprudence;
Treating a stepchild or foster child as legally adopted;
Signing a waiver without knowing the share being waived or its tax consequences;
Using an affidavit of self-adjudication despite the existence of other heirs;
Publishing a settlement and assuming publication cures an omitted heir;
Selling a specific inherited asset before a valid partition and without the necessary consent;
Ignoring lifetime donations that may affect legitimes;
Distributing assets before paying debts and taxes;
Believing a notarized document is automatically valid or immune from challenge;
Applying today’s tax rules to a death that occurred under an older law; and
Waiting until witnesses, documents, or property records disappear.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

Someone is hiding, destroying, or refusing to produce a will;
An estate property is about to be sold, mortgaged, demolished, or transferred;
A suspected forged deed, waiver, will, or affidavit has been registered;
An heir—especially a minor—was omitted;
Bank funds, rent, crops, or business income are being withdrawn without accounting;
Filiation, adoption, marriage, or legitimacy is contested;
The family received a court summons, BIR assessment, foreclosure notice, or demand from a creditor;
The deceased owned a business, foreign property, or property in several jurisdictions;
The estate has substantial debts or insolvency concerns;
An heir is being pressured to sign immediately;
Prescription, laches, or a Rule 74 two-year issue is being raised; or
There is a risk of violence, intimidation, falsification, or concealment of property.

Emergency relief may depend on prompt evidence and the exact threatened transaction. Do not sign a settlement merely to “keep the peace” if the assets, heirs, and legal shares have not been disclosed.

Special cases

The Civil Code rules above are not universal in every estate. Important exceptions include:

Muslim succession: Presidential Decree No. 1083 contains distinct succession rules applicable in circumstances covered by the Code of Muslim Personal Laws.
Foreign nationals: Under Article 16 of the Civil Code, succession to movable and immovable property is generally governed by the decedent’s national law regarding the order of succession, amount of successional rights, and intrinsic validity of testamentary provisions, while Philippine rules may govern other issues.
Agrarian, ancestral-domain, corporate, pension, insurance, and trust assets: Special laws, restrictions, or contractual beneficiary rules may affect transfer.
Deaths occurring under older laws: Tax rates, deductions, filing requirements, and sometimes relevant family-law consequences depend on the date of death.

Frequently asked questions

Can a parent leave everything to only one child?

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

Does the eldest child receive a bigger share?

No. Birth order does not generally increase a child’s inheritance share.

Can daughters inherit land equally with sons?

Yes. Sex does not reduce a child’s succession rights under the Civil Code.

Does using the father’s surname prove the right to inherit?

Not conclusively. Surname use and filiation are related but distinct. The legally accepted proof of filiation and the circumstances of the record or acknowledgment must be examined.

Can an illegitimate child inherit from the father?

Yes, if paternal filiation is legally established. The child is a compulsory heir of the father, although the statutory share differs from that of a legitimate child.

Can grandchildren inherit while their parent is alive?

Usually, the nearer descendant excludes the more remote descendant. Exceptions may arise through a will’s disposable portion or where a legally recognized basis for representation exists. A living parent’s simple refusal to accept ordinarily does not create representation for that parent’s children.

Does a common-law partner inherit automatically?

No. Only a legally recognized surviving spouse has spousal succession rights. A partner may have separate co-ownership, reimbursement, contractual, or beneficiary claims, depending on the facts.

May one heir sell the inherited family home?

Before partition, an heir may generally deal only with that heir’s hereditary interest, not unilaterally convey the other heirs’ shares or guarantee ownership of a particular estate asset. Any sale must also account for co-ownership rules, estate obligations, registration requirements, and applicable rights of co-heirs.

Can an heir refuse an inheritance?

Yes, but repudiation must comply with the form required by Article 1051 of the Civil Code—generally through a public or authentic instrument or a petition presented to the court handling the estate. A waiver made after accepting or disposing of inherited property may be ineffective as a repudiation and may create tax consequences.

Is a verbal family agreement enough?

It is unsafe and often legally insufficient, particularly when land is involved. A valid settlement or partition should meet the required formalities and be registered where necessary.

Does the two-year Rule 74 period erase an omitted heir’s claim?

Not automatically. The two-year rule addresses specified remedies against distributees and the bond. The proper deadline for a particular action can depend on lack of notice, fraud, possession, registration, the relief sought, and other facts.

Who pays the deceased’s debts?

Estate obligations are generally settled from estate assets before final distribution. Heirs should not divide or dispose of everything while valid creditor claims remain unresolved. Personal liability depends on the property received, the transaction signed, and the governing procedural rules.
