Quick answer

Philippine law does not allow a person to distribute an entire estate freely when compulsory heirs exist. Legitimate children and descendants, qualifying legitimate parents or ascendants, the surviving legal spouse, illegitimate children whose filiation is proved, and legally adopted children may have protected inheritance rights.

The exact share depends on:

whether there is a valid will;
who survived the deceased;
each claimant’s legally established relationship to the deceased;
the property regime of the marriage;
which assets actually belonged to the deceased;
enforceable debts, taxes, and estate expenses;
lifetime donations that may require collation or reduction; and
whether special laws, including Muslim personal law, apply.

A title, bank account, or business asset bearing the deceased’s name is not automatically divisible in full among the heirs. The surviving spouse’s ownership in community or conjugal property must generally be determined first. Only the deceased’s share, together with other estate assets and subject to lawful obligations, forms the hereditary estate.

Inheritance rights arise at death, but heirs should not sell, transfer, withdraw, or divide specific assets until the estate and the heirs’ respective shares have been properly established.

Who may inherit

Succession may be:

Testamentary, under a valid will;
Intestate, under the order fixed by law when there is no effective will or the will does not cover the whole estate; or
Mixed, when part of the estate passes by will and the remainder passes by intestacy.

The governing succession law is generally the law in force when the deceased died. Citizenship, domicile, property location, Muslim status, foreign wills, and deaths occurring under older laws can materially change the analysis.

Compulsory heirs

Under Articles 886–887 of the Civil Code, compulsory heirs are persons for whom the law reserves a legitime, or a protected minimum share. Depending on who survives, they include:

legitimate children and descendants;
in their default, legitimate parents and ascendants;
the surviving widow or widower;
illegitimate children whose filiation is duly proved; and
adopted children, who are treated as legitimate children of their adopters for succession purposes.

Legitimate parents or ascendants are generally excluded by legitimate children or descendants. The surviving spouse and illegitimate children may concur with other compulsory heirs rather than being automatically excluded.

A spouse must be the deceased’s legal spouse. A fiancé, long-term partner, or common-law partner does not become an intestate heir merely because the couple lived together or had children. That partner may still own a separate share in property acquired during the relationship under Articles 147 or 148 of the Family Code, or may inherit from the disposable portion under a valid will.

A spouse who gave cause for a judicial decree of legal separation may lose inheritance rights under the applicable provisions. Mere physical separation, without a decree, is not automatically equivalent to legal separation.

Adopted children

Under Sections 41–43 of Republic Act No. 11642, an adoptee is considered the adopter’s legitimate child, and adopter and adoptee have reciprocal testate and intestate succession rights without distinction from legitimate filiation. Adoption records, the date and legal effect of the adoption, step-parent adoption, rescission, and succession involving biological parents require document-specific review.

Illegitimate children

An illegitimate child may inherit directly from a parent if filiation is legally established. Article 176 of the Family Code provides that each illegitimate child’s legitime is generally one-half of the legitime of a legitimate child, subject to the other succession rules and the available estate.

Proof of filiation is therefore critical. A birth certificate, written acknowledgment, final judgment, or other evidence recognized by law may be necessary. Family reputation or verbal statements alone may not settle a contested claim.

The Supreme Court’s ruling in Aquino v. Aquino adopted a child-protective interpretation of Article 992: children, regardless of the circumstances of birth, may inherit from their direct ascendants, such as grandparents, by representation. This ruling should not be treated as abolishing every restriction involving collateral relatives. Claims involving grandparents, half-siblings, uncles, aunts, or cousins remain highly fact-sensitive.

If there is a will

A will does not automatically allow the testator to give everything to one favored person. The will must satisfy statutory formalities and must respect the legitimes of compulsory heirs.

The will must be probated

Under Rule 75 of the Rules of Court, a will generally cannot pass property unless it is proved and allowed in the proper court. A private agreement declaring a will “valid” is not a substitute for probate.

The probate court principally determines whether the will was executed with the required formalities and whether the testator had testamentary capacity and acted voluntarily. Questions about ownership, legitimes, omitted heirs, and the validity of particular dispositions may require additional determination during the estate proceedings.

A compulsory heir cannot be excluded casually

A compulsory heir may be deprived of a legitime only through a legally valid disinheritance:

it must be made in a will;
it must identify a cause expressly recognized by law; and
if challenged, the cause must be proved by the persons who benefit from the disinheritance.

Family disagreement, disapproval of a marriage, unequal financial success, or a general statement that an heir was “ungrateful” is not necessarily a statutory cause.

Preterition and impaired legitimes

Preterition generally means the total omission of a compulsory heir in the direct line from the inheritance, without the heir having received anything by will or otherwise. When its legal requirements are met, preterition can annul the institution of heirs, although valid legacies and devises may remain effective insofar as they are not inofficious.

A disposition that merely gives a compulsory heir less than the required legitime is generally subject to completion or reduction rather than automatically invalidating the entire will. The remedy depends on whether the problem is true preterition, defective disinheritance, impairment of legitime, or another testamentary defect.

If there is no valid will

Intestate succession applies when a person dies without a will, with a void or ineffective will, or with a will that does not dispose of the entire estate.

The Civil Code generally gives priority to the nearest relatives, subject to concurrence and the right of representation. A practical—not exhaustive—order is:

legitimate children and descendants;
legitimate parents and ascendants, if there are no legitimate descendants;
illegitimate children and their descendants, as provided by law;
the surviving legal spouse, alone or together with certain relatives;
brothers, sisters, nephews, and nieces;
other collateral relatives within the fifth civil degree; and
the State, if no qualified heir exists.

This is not a simple one-person-at-a-time ladder. The surviving spouse and illegitimate children frequently concur with descendants or ascendants.

Common intestate combinations

Subject to representation and other applicable rules:

Surviving spouse and legitimate children: The spouse generally receives a share equal to that of each legitimate child.
Surviving spouse and legitimate parents or ascendants: The spouse generally receives one-half, and the legitimate parents or ascendants receive the other half.
Surviving spouse and illegitimate children only: The spouse generally receives one-half, while the illegitimate children or their qualifying descendants share the other half.
Surviving spouse, legitimate children, and illegitimate children: The spouse generally receives the same share as a legitimate child; the illegitimate children receive the shares provided by law.
Surviving spouse and siblings, nephews, or nieces, with no descendants, ascendants, or illegitimate children: The spouse generally receives one-half, and the siblings or their qualifying children receive the other half.
Surviving spouse alone: The spouse generally receives the entire intestate estate.
Illegitimate children without a surviving spouse, legitimate descendants, or legitimate ascendants: They may inherit the entire estate under the applicable provisions.
Siblings of full and half blood: They do not always receive equal amounts; the Civil Code gives a full-blood sibling twice the share of a half-blood sibling when they inherit together.

These ratios apply to the distributable hereditary estate—not automatically to the gross value of every asset associated with the deceased.

Representation: when descendants take a deceased heir’s place

Representation allows specified descendants to step into the place of a person who died before the decedent, is legally incapacitated to inherit, or was disinherited in a manner covered by law.

It commonly operates:

without limit in the direct descending line, subject to the governing rules; and
in the collateral line only in favor of children of brothers or sisters, when they concur with surviving siblings.

Representation generally does not arise merely because an heir voluntarily renounced an inheritance. Whether grandchildren inherit in their own right or by representation affects how the estate is divided by family branch.

The estate must be identified before shares are computed

Separate marital property from estate property

Before distributing an estate, determine the spouses’ property regime, which may be:

absolute community of property;
conjugal partnership of gains;
complete separation of property; or
another valid regime under a marriage settlement or applicable law.

Property acquired during marriage may be presumed community or conjugal property, subject to proof and the applicable regime. The surviving spouse’s own share is not an inheritance. It must ordinarily be separated before the deceased’s net estate is divided.

Verify ownership instead of relying only on possession

Prepare an inventory that covers, where applicable:

land and condominium titles;
tax declarations and real-property tax records;
bank and investment accounts;
shares of stock and partnership interests;
vehicles;
businesses and receivables;
insurance proceeds payable to the estate;
intellectual property and digital assets;
valuable personal property;
property held jointly or in trust;
assets transferred before death; and
obligations owed by or to the deceased.

A certificate of title is strong evidence, but it may not resolve whether property was exclusive, community, conjugal, held in trust, or already transferred. Conversely, possession alone does not prove ownership.

Pay or account for lawful obligations

The estate is settled subject to enforceable debts, taxes, administration expenses, and other lawful charges. Heirs should not divide all cash or dispose of estate property while creditor claims and taxes remain unresolved.

Before partition, multiple heirs generally own the estate in common, subject to estate obligations. A co-heir may transfer only the hereditary interest legally available to that heir—not another heir’s share or an exclusive right to a specific estate asset that has not yet been allotted.

Lifetime gifts can affect the final division

A parent’s lifetime donation is not always separate from the later inheritance calculation. Certain donations to compulsory heirs may be subject to collation, meaning their value is brought into the estate accounting to determine legitimes and equality of partition.

A donation that exceeds the disposable portion may be reduced after death to protect compulsory heirs. Whether a transfer was a genuine sale, donation, advancement, simulated transaction, or property held in trust depends on the documents, payment records, possession, and surrounding facts.

Preserve deeds of donation or sale, proof of payment, tax records, bank transfers, appraisals, and correspondence concerning the purpose of the transfer.

Accepting or renouncing an inheritance

Acceptance or repudiation generally takes effect retroactively from the moment of death. Acceptance may be express or implied through conduct that necessarily shows an intention to accept.

Renunciation must comply with the Civil Code’s formal requirements. It should not be improvised through a family waiver or unsigned message. A waiver made in favor of selected co-heirs may have consequences different from a pure repudiation and may create tax or transfer issues.

Before signing, the heir should confirm:

the estate’s assets and debts;
the actual hereditary share;
pending litigation or tax exposure;
whether the waiver is gratuitous or for consideration;
whether children could claim by representation; and
whether the document is really a sale, donation, assignment, or partition.

An heir generally cannot accept only profitable assets while rejecting the estate’s burdens, or accept one part and repudiate another, as though each asset were a separate inheritance.

How an estate may be settled

Extrajudicial settlement

Rule 74 permits extrajudicial settlement when, among other requirements:

the deceased left no will;
the estate has no outstanding debts;
all heirs participate;
the heirs are of legal age, or minors are properly represented as the rule requires;
the agreement is in a public instrument; and
the fact of settlement is published once a week for three consecutive weeks in a newspaper of general circulation.

If there is only one heir, that heir may use an affidavit of self-adjudication when the legal conditions are met.

For registered land, the deed or affidavit must be registered, and the two-year lien under Rule 74 is annotated on the title pursuant to Section 86 of Presidential Decree No. 1529.

Extrajudicial settlement is inappropriate when there is a contested will, an unresolved heirship dispute, an unpaid estate debt, an heir who cannot validly consent, or a material disagreement over ownership or shares. Publication does not give participating heirs the right to erase a known heir. Rule 74 also protects persons who did not participate or had no notice in the manner provided by the rule.

Judicial settlement

Court proceedings are generally needed when:

a will must be probated;
the appointment of an executor or administrator is necessary;
heirs or creditors dispute the estate;
property ownership is contested;
an heir is missing or inadequately represented;
the estate has unresolved debts;
documents are suspected to be forged or simulated; or
the heirs cannot agree on partition.

Venue usually depends on the deceased’s residence at the time of death. Special rules apply to nonresidents with property in the Philippines.

Estate tax and transfer requirements

For deaths covered by the TRAIN-law regime, the estate tax is generally 6% of the net taxable estate, not 6% of each heir’s gross inheritance.

Under Revenue Regulations No. 12-2018:

the estate tax return is generally due within one year from death;
a standard deduction of ₱5 million is available for a citizen or resident decedent under the applicable rules;
a family-home deduction of up to ₱10 million may be available if its statutory conditions are met;
a return involving a gross estate exceeding ₱5 million must include the statement certified by an independent certified public accountant required by law; and
approved extensions or installment arrangements may be available in qualifying cases, but they must be requested and should not be assumed.

The tax law in force on the date of death governs estate taxation. Older estates may therefore have different rates, deductions, deadlines, and documentary requirements.

Republic Act No. 11956 extended the estate-tax amnesty only until June 14, 2025. As of the source-check date below, that statutory availment period has expired. Families with unsettled older estates should not assume they can still use the amnesty; they should obtain a current BIR computation and advice on ordinary settlement, penalties, and available remedies.

The estate ordinarily needs a separate taxpayer identification number, the proper estate tax return, supporting ownership and valuation documents, payment or approved arrangement, and a BIR electronic Certificate Authorizing Registration before covered property can be transferred. Filing venue and required documents depend on whether the deceased was a resident and whether an executor or administrator exists.

Because BIR forms and transaction channels can change, confirm the current checklist with the appropriate Revenue District Office or the BIR’s official estate-tax and ONETT services.

Practical steps for heirs

Secure civil-registry documents. Obtain the death certificate and relevant birth, marriage, adoption, annulment, and legal-separation records.
Locate the original will. Do not alter, annotate, conceal, or discard it. Ask the custodian or named executor to obtain advice about delivery and probate.
Prepare a complete family tree. Include legitimate, illegitimate, adopted, predeceased, minor, incapacitated, and overseas relatives. Record dates of birth and death.
Inventory assets and debts. Request official records from banks, corporations, registries, insurers, creditors, and government offices through the legally authorized representative.
Determine the marital property regime. Find the marriage certificate, marriage settlement, property acquisition documents, and proof of exclusive funds.
Protect estate property. Secure titles, keys, vehicles, business records, devices, and accounts. Continue essential preservation expenses and keep receipts.
Do not make informal distributions. Avoid undocumented withdrawals, private sales, secret occupancy agreements, or division based only on verbal promises.
Value the estate as of death. Obtain the required zonal, assessed, market, corporate, or professional valuations applicable to each asset.
Identify the proper settlement route. Decide whether the estate qualifies for extrajudicial settlement or requires probate or administration.
Address estate tax promptly. The one-year filing period can expire while the family is still negotiating. A family disagreement does not automatically suspend the tax deadline.
Execute and register the correct documents. Comply with notarization, publication, BIR, Registry of Deeds, corporate, vehicle, and bank requirements.
Keep a distribution accounting. Record all income, expenses, advances, tax payments, reimbursements, and assets received by each heir.

Evidence to preserve

Keep originals or authenticated copies of:

the death certificate;
all wills and codicils;
birth, marriage, adoption, and court records;
land titles, deeds, tax declarations, and tax receipts;
bank statements and investment records near the date of death;
stock certificates, corporate records, and business books;
loan agreements, mortgages, promissory notes, and creditor demands;
insurance and retirement-benefit documents;
marriage settlements and proof of how assets were acquired;
deeds of donation, sale, waiver, assignment, and trust documents;
proof of payment for alleged sales;
messages or letters concerning ownership and lifetime advances;
inventories, photographs, appraisals, and possession records;
estate expenses and funeral receipts; and
copies of every settlement, publication, BIR filing, eCAR, and registration receipt.

Use lawful access methods. Do not guess passwords, impersonate the deceased, destroy records, or move assets to defeat other heirs or creditors.

Common mistakes

Treating the eldest child as the automatic owner or decision-maker;
assuming daughters and sons receive different shares;
excluding an illegitimate child without examining proof of filiation;
excluding an adopted child;
treating a common-law partner as a legal spouse—or ignoring that partner’s possible ownership share;
dividing the entire value of community or conjugal property as the deceased’s estate;
relying on a will that has never been probated;
assuming a handwritten or notarized paper is automatically a valid will;
using extrajudicial settlement despite debts, a will, missing heirs, or unresolved disputes;
omitting an heir from the deed and relying on newspaper publication to cure the omission;
selling a specific estate asset before partition without authority from all persons whose interests are affected;
signing a waiver without an inventory and valuation;
ignoring lifetime donations and possible collation;
waiting for family agreement before addressing the estate-tax deadline; and
assuming the expired estate-tax amnesty remains available.

When legal help is urgent

Seek prompt advice from a Philippine succession lawyer if:

the original will may be lost, hidden, forged, or destroyed;
someone is withdrawing funds or selling property without authority;
an heir was omitted from an extrajudicial settlement;
a minor, incapacitated person, or missing heir is involved;
filiation, adoption, marriage, or legitimacy is disputed;
the estate-tax deadline is near or has passed;
foreclosure, eviction, dissipation, or prescription may occur;
signatures or deeds appear forged or simulated;
the deceased was a foreign national or owned property abroad;
the family may be governed by the Code of Muslim Personal Laws;
the estate includes a closely held company or disputed corporate shares; or
heirs cannot agree on possession, management, valuation, or partition.

Qualified indigent persons may ask the Public Attorney’s Office whether they meet its assistance requirements. Court-supervised remedies may also be necessary to preserve property or compel an accounting.

Frequently asked questions

Can a parent leave everything to only one child?

Usually not if other compulsory heirs survive. A will may favor one child only within the disposable portion and through arrangements that do not impair the others’ legitimes. A valid statutory disinheritance is different from merely naming a favorite heir.

Does the eldest child receive a larger share?

No general Philippine succession rule gives the eldest child a larger share solely because of age or birth order.

Do married daughters lose inheritance rights?

No. Marriage does not by itself remove a child’s inheritance rights.

Can an illegitimate child inherit from the father?

Yes, if filiation is duly proved and no specific legal disqualification applies. The amount depends on the other heirs and whether succession is testate or intestate.

Can grandchildren inherit while their parent is alive?

Ordinarily, the nearer descendant excludes the more remote descendant. Grandchildren may inherit in particular circumstances, including representation, a valid testamentary disposition, or when they are otherwise called by law. The family structure must be examined carefully.

Does a common-law partner inherit automatically?

No. Only a surviving legal spouse has the spouse’s statutory inheritance rights. A common-law partner may nevertheless own part of property acquired during cohabitation or receive property under a valid will within the disposable portion.

Is inherited property automatically conjugal property?

Property acquired by gratuitous title during marriage is generally treated as exclusive property under the applicable marital regime, subject to the terms of the donation or will and other legal rules. Income, improvements, commingling, and older property regimes can complicate the result.

Can one heir sell inherited land without the others?

Before partition, an heir may generally transfer only the heir’s undivided hereditary interest, subject to estate obligations and the rights of co-heirs. The heir cannot validly sell the other heirs’ shares. A supposed sale of a specific portion may ultimately affect only what is allotted to the seller.

What if an heir was omitted from an extrajudicial settlement?

The omitted heir may have remedies to recover the proper share, challenge documents, demand partition, or pursue the persons and property legally liable. Rule 74 contains a two-year protection period for certain claims against distributees, with special provisions for persons under disability or outside the Philippines, but not every heirship or fraud claim is governed identically. Obtain advice immediately rather than assuming the claim has either expired or remains indefinitely available.

Do heirs inherit the deceased’s debts personally?

Debts are generally chargeable against the estate. An heir is ordinarily liable only within the value or property received from the estate, subject to applicable rules and any separate personal undertaking. Heirs should not distribute estate assets before valid obligations are addressed.

Can heirs settle the estate without going to court?

Yes, but only when the requirements for extrajudicial settlement are satisfied. A will requiring probate, unresolved debts, missing participation, inadequate representation, or a substantial dispute usually requires judicial proceedings.
