Quick answer

Under Philippine law, an heir’s rights depend on four questions: Who died? What property actually belonged to that person? Is there a valid will? Who survived the decedent?

A valid will generally controls succession, but it cannot unlawfully reduce the reserved shares—or legitimes—of compulsory heirs. If there is no valid will, the Civil Code’s rules on intestate succession determine who inherits and in what proportions. In either case, the estate’s enforceable debts, taxes, administration expenses, and the surviving spouse’s own property share must be settled before the net inheritance is distributed.

Children cannot ordinarily be deprived of their legitime merely because of estrangement, family conflict, or a statement in a will. Disinheritance is effective only for a cause expressly recognized by law and stated in a valid will. At the same time, being related to the decedent does not always make someone an heir: nearer relatives may exclude more remote relatives, and filiation, marriage, adoption, representation, unworthiness, renunciation, and prior transfers can change the result.

The controlling rules are principally found in the Civil Code provisions on succession, the Family Code, and the Rules of Court on settlement of estates.

When inheritance rights begin

Succession opens at the moment of death. From that point, hereditary rights are transmitted to qualified heirs, subject to the settlement of the estate and the heir’s acceptance or repudiation.

An heir does not automatically become the exclusive owner of a particular house, lot, vehicle, or bank account. Until partition, the heirs generally hold the inherited estate in common. A co-heir normally cannot validly sell the entire property without the authority or consent of the other owners, although an heir may transfer only the hereditary rights or undivided interest that ultimately belongs to that heir.

The distributable estate must first be identified:

Determine which assets belonged to the decedent.
Separate the surviving spouse’s share in community or conjugal property, if applicable.
Include property that legally forms part of the gross estate.
Account for enforceable debts, taxes, expenses, and allowable deductions.
Examine lifetime donations that may have to be brought into account or reduced.
Apply the will, if valid, without impairing compulsory heirs’ legitimes.
Divide the remaining net estate among the proper heirs.

A land title, tax declaration, bank record, or possession of property is important evidence, but it may not by itself settle beneficial ownership. Property regimes, simulated transfers, trusts, unpaid purchases, donations, and prior partitions can affect what actually belongs to the estate.

The three ways an estate may pass

Testamentary succession

Testamentary succession applies when the decedent left a valid will. The will identifies heirs, devisees, or legatees, but its provisions remain subject to formal validity, the testator’s capacity, legal prohibitions, and the legitimes of compulsory heirs.

A will has no operative effect merely because relatives possess a signed copy. Under Rule 75, a will must be presented and allowed in probate before it can pass property. Even a notarized will may be denied probate if mandatory execution requirements were not met.

Intestate succession

Intestate succession applies when:

there is no will;
the will is void or is not allowed in probate;
the will fails to dispose of the entire estate;
an instituted heir cannot or will not inherit and no valid substitute or other rule covers the share; or
another circumstance specified by law opens intestacy.

A person may therefore die partly testate and partly intestate.

Mixed succession

Mixed succession occurs when part of the estate passes under a valid will and the remainder passes by law. This commonly happens when the will covers only selected property or an institution of heir fails.

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 the absence of legitimate children or descendants, legitimate parents and ascendants;
the surviving spouse; and
illegitimate children, subject to the Civil Code and Family Code.

The descendants of a child who is predeceased, disinherited, or incapable of inheriting may qualify by right of representation where the law permits. Representation places the representative in the degree and share of the person represented; the representatives divide that branch’s share among themselves.

Adopted children generally have the status and succession rights of legitimate children of the adopters. Under the current adoption law, adopters and adoptees have reciprocal succession rights without distinction from legitimate filiation, subject to the rules governing wills and the particular adoption involved. See Republic Act No. 11642.

Brothers, sisters, nephews, nieces, and more remote relatives are not compulsory heirs merely because they are family members. They may inherit under a will or under intestacy when the relatives preferred by law do not exist, cannot inherit, or validly renounce.

The legitime: the share reserved by law

A legitime is the portion of the estate that the testator cannot freely dispose of because the law reserves it for compulsory heirs. The balance after all legitimes are protected is the free portion.

Common rules include:

Family situation	General legitime rule
Legitimate children or descendants	Collectively receive one-half of the net hereditary estate, divided equally by heads or branches as applicable
Legitimate parents or ascendants, with no legitimate descendants	Collectively receive one-half
Surviving spouse with legitimate children	The spouse generally receives a share equal to the legitime of one legitimate child
Surviving spouse with legitimate parents or ascendants	Spouse receives one-fourth; parents or ascendants collectively receive one-half
Surviving spouse alone	Generally receives one-half
Illegitimate child with legitimate children	Generally receives one-half of the share of a legitimate child, subject to preservation of the spouse’s legitime and the free portion
Illegitimate children without legitimate descendants	Collectively generally receive one-half
Surviving spouse with illegitimate children but no legitimate descendants or ascendants	Spouse generally receives one-third and the illegitimate children collectively receive one-third

These are legitime rules, not a universal table for every estate. The exact computation can change when several classes concur, when heirs inherit by branch, when there are lifetime donations, or when the estate is partly intestate. The arithmetic should be done only after the property regime and net hereditary estate are established.

Who inherits when there is no valid will?

The general intestate order gives preference to:

legitimate children and descendants;
legitimate parents and ascendants, if there are no legitimate descendants;
illegitimate children and their qualified descendants;
the surviving spouse;
brothers, sisters, nephews, and nieces;
other collateral relatives within the fifth civil degree; and
the State.

These groups do not simply divide the estate equally. Concurrence and exclusion rules apply. Important examples include:

Legitimate children inherit in equal shares, subject to representation by branches.
An illegitimate child inherits directly from the child’s own parent, provided filiation is legally established.
When legitimate and illegitimate children inherit together, each illegitimate child generally receives one-half of the share of each legitimate child.
A surviving spouse who concurs with legitimate children generally receives a share equal to one legitimate child.
When the surviving spouse concurs only with illegitimate children, the spouse generally receives one-half and the illegitimate children collectively receive the other half.
When the spouse concurs with legitimate parents or ascendants, the spouse generally receives one-half and the parents or ascendants the other half.
If there are no descendants or ascendants but siblings or qualifying nephews and nieces survive, the surviving spouse generally receives one-half and those collateral relatives receive the other half.
A surviving spouse generally receives the entire intestate estate when no descendants, ascendants, illegitimate children, or qualifying siblings, nephews, or nieces concur.

A more remote relative is generally excluded by a nearer relative, except where representation is authorized.

Rights of children born outside marriage

An illegitimate child has inheritance rights from the child’s own mother and, when filiation is legally established, from the child’s own father. The child’s compulsory share is generally one-half of the share of a legitimate child when they inherit together.

Filiation is often the decisive issue. A birth certificate, record of admission, final judgment, or other proof recognized under the Family Code may be necessary. The use of the father’s surname alone does not necessarily resolve every question of filiation or inheritance.

Article 992 of the Civil Code also creates a significant restriction in intestate succession between an illegitimate child and the legitimate children and relatives of that child’s parent. The Supreme Court has continued to apply this statutory “iron curtain” to the circumstances covered by the provision. Its effect can be especially important when a grandchild claims by representation through a predeceased parent. See the Supreme Court’s discussion in Aquino v. Aquino, G.R. Nos. 208912 and 209018.

This restriction should not be applied casually. The result depends on the family lines, the marital status relevant to those lines, whether succession is testate or intestate, and whether the claimant is inheriting directly or by representation.

Rights of the surviving spouse and unmarried partner

A legally surviving spouse is a compulsory heir. The spouse’s inheritance is distinct from the spouse’s ownership of a share in community or conjugal property.

For example, if a house is community property, the surviving spouse’s own share must first be separated. Only the decedent’s share enters the estate, and the surviving spouse may then inherit from that estate together with the other heirs.

A person who was merely separated in fact may still be a surviving spouse. Legal separation, annulment, nullity, a prior subsisting marriage, and the circumstances of remarriage can materially change the answer. A spouse legally separated from the decedent may be disqualified when the spouse was the guilty party under the applicable Civil Code provisions.

An unmarried cohabiting partner is not treated as a surviving spouse for compulsory or intestate succession. The partner may nevertheless own a share in property acquired during the relationship under Articles 147 or 148 of the Family Code, depending on the parties’ capacity to marry and their actual contributions. That ownership claim is separate from inheritance.

Can a parent disinherit a child?

Only through a valid will and only for a statutory cause.

For children and descendants, Article 919 recognizes specific causes, including certain serious acts against the testator or close family members, unjustified refusal of support, maltreatment, leading a dishonorable or disgraceful life, and specified criminal or marital circumstances. The cause must be stated in the will. If the disinherited heir denies it, the heirs who benefit from the disinheritance generally must prove the cause.

Statements such as “we no longer speak,” “the child did not visit,” or “I already helped that child” do not automatically amount to valid disinheritance. If the cause is not one provided by law, is not stated properly, or is not proved when challenged, the disinheritance may be ineffective to the extent that it prejudices the heir’s legitime.

Reconciliation between the testator and the offended heir can deprive the testator of the right to disinherit or render an earlier disinheritance ineffective.

What if a compulsory heir was omitted from the will?

Complete and unintentional omission of a compulsory heir in the direct line may constitute preterition under Article 854. Preterition can annul the institution of heirs, while devises and legacies remain valid only insofar as they are not excessive.

Preterition is not established merely because an heir received less than expected. It generally requires total omission: the heir was neither instituted nor expressly disinherited and received no qualifying devise, legacy, or advance on the legitime. An heir who received something but less than the full legitime ordinarily seeks completion or reduction of excessive dispositions instead.

Because the remedy differs sharply between preterition, defective disinheritance, and simple impairment of a legitime, the complete will and records of lifetime transfers should be reviewed together.

Can an heir refuse an inheritance?

Yes. Acceptance or repudiation is voluntary, but once validly made it is generally irrevocable, except in circumstances recognized by law.

Repudiation must comply with Article 1051: it must be made in a public or authentic instrument or through a petition presented to the court handling the estate. Silence, absence from family meetings, or failure to sign one proposed settlement is not necessarily a valid repudiation.

An heir should not renounce before determining:

the estate’s assets and liabilities;
whether the waiver is in favor of the estate generally or of identified co-heirs;
possible estate and donor’s tax consequences;
whether the heir has creditors who may challenge the repudiation; and
whether the document is actually a sale, donation, partition, or compromise.

A waiver made after accepting benefits or exercising ownership may be disputed. If an heir repudiates to prejudice creditors, the creditors may seek authority to accept in the heir’s name to the extent necessary to cover their claims.

Grounds that may prevent an heir from inheriting

An otherwise qualified heir may be excluded because of incapacity or unworthiness under Articles 1027 and 1032, including specified conduct such as an attempt against the life of the decedent or certain close relatives, a qualifying criminal accusation, coercion or fraud involving a will, or concealment or alteration of a will.

These grounds are technical and fact-dependent. Family misconduct that seems unfair does not automatically amount to legal unworthiness. Pardons, reconciliation, criminal judgments, and the time for bringing an action may affect the result.

How an estate is settled

If there is a will

The will must be presented for probate. The proper court determines whether it was executed according to law and whether the testator had the required testamentary capacity. An executor named in the will may be appointed, or the court may appoint an administrator.

If there is no will but judicial administration is needed

Judicial settlement is usually appropriate when:

heirs disagree;
a will must be probated;
heirs or creditors have been omitted;
substantial debts remain;
the identity or filiation of an heir is disputed;
property ownership is contested;
an heir is missing or inadequately represented;
transfers must be recovered or annulled; or
court authority is needed to preserve or dispose of property.

Extrajudicial settlement

Rule 74 permits extrajudicial settlement when the decedent left no will and no debts, and all heirs are adults or minors are properly represented by duly authorized judicial or legal representatives. The heirs execute a public instrument; a sole heir may use an affidavit of self-adjudication. The settlement must be published in a newspaper of general circulation and, where real property is involved, filed with the Register of Deeds with the required bond concerning personal property.

Publication does not cure the exclusion of an heir. The rule expressly states that an extrajudicial settlement is not binding on a person who did not participate or had no notice. The Supreme Court has emphasized these conditions in Treyes v. Antonio, G.R. No. 232579 and subsequent estate-settlement decisions.

Rule 74 also provides a two-year remedy in specified circumstances for unpaid debts or a person unduly deprived of lawful participation following a summary or extrajudicial settlement. That period is not a safe license to omit an heir, and it does not necessarily extinguish every remedy available to a person who never participated or had no notice. Prescription, laches, fraud, registration, and the rights of purchasers require case-specific analysis.

Estate tax and transfer requirements

For deaths covered by the TRAIN-era rules, the estate tax is generally 6% of the net taxable estate. The regulations provide, among other deductions, a ₱5 million standard deduction for a citizen or resident decedent and a family-home deduction of up to ₱10 million, subject to statutory conditions. Different laws and rates may apply when the death occurred before January 1, 2018.

The estate tax return is generally due within one year from death, and the tax is generally paid when the return is filed. A reasonable filing extension of no more than 30 days may be requested in meritorious cases. Payment extensions or approved installment arrangements may be available in cases of undue hardship or insufficient cash, subject to BIR approval and conditions.

Before registered property can ordinarily be transferred to heirs, the estate must obtain the necessary BIR clearance or electronic Certificate Authorizing Registration. Filing requirements depend on the date of death, assets, deductions, property locations, and whether the decedent was resident or nonresident. Consult the BIR estate-tax page, the BIR’s Consolidated Revenue Regulations on Estate Tax and Donor’s Tax, and the current RDO documentary checklist before filing.

Do not assume that an old estate is tax-free or that penalties disappear because the heirs delayed settlement. Any prior estate-tax amnesty must be checked against its statutory coverage and filing deadline; it should not be presumed available.

Practical steps for an heir

Secure death and civil-registry records. Obtain the PSA death certificate and relevant birth, marriage, adoption, annulment, and death records.
Locate the original will. Preserve the document and do not mark, staple, alter, or conceal it.
Build a complete family tree. Include deceased children, children born outside marriage, adopted children, prior spouses, and descendants who may represent a deceased heir.
Inventory assets and debts. List land, condominium units, vehicles, bank accounts, shares, businesses, insurance proceeds payable to the estate, digital assets, loans, taxes, and pending claims.
Determine the marital property regime. Collect marriage records, prenuptial agreements, titles, acquisition dates, and proof of contributions.
Preserve property values. Secure premises, maintain insurance, prevent unauthorized withdrawals, and document income and expenses.
Check titles and corporate records. Obtain certified copies rather than relying on photographs or family recollection.
Request an accounting. Anyone managing estate money should record all collections, withdrawals, rent, taxes, repairs, and distributions.
Compute shares only after classifying the estate. Do not divide gross property values without first separating ownership, debts, taxes, and legitimes.
Use the correct settlement process. Probate a will; use an extrajudicial settlement only when Rule 74’s conditions are genuinely satisfied.
Address tax deadlines early. Register the estate, secure its TIN, prepare the return, and ask the proper BIR RDO about current documentary and payment requirements.
Register the final transfers. Obtain the eCAR and complete Registry of Deeds, local assessor, bank, corporate, and other transfer requirements.

Evidence worth preserving

Keep originals or certified copies of:

the will, codicils, and envelopes or custody records;
PSA civil-registry documents;
adoption or filiation decisions and acknowledgments;
land titles, deeds, tax declarations, surveys, and lease contracts;
bank statements, passbooks, investment records, and loan documents;
corporate books, stock certificates, partnership records, and business permits;
insurance policies and beneficiary designations;
marriage settlements and proof of property contributions;
donation, sale, waiver, partition, and settlement documents;
medical records relevant to testamentary capacity, where lawfully obtainable;
communications concerning the will, property, debts, or threats;
receipts for funeral, medical, tax, preservation, and administration expenses; and
proof showing possession, rentals collected, and changes made to estate property.

Preserve electronic files in their original format with dates and metadata when possible. Do not secretly access protected accounts or devices without legal authority.

Common mistakes

Dividing community or conjugal property as if the entire asset belonged to the decedent.
Treating every relative as a compulsory heir.
Assuming a parent can disinherit a child through a verbal declaration.
Using an affidavit of self-adjudication despite the existence of another heir.
Excluding a child because the child did not use the father’s surname.
Assuming publication validates an extrajudicial settlement that omitted an heir.
Selling a specific estate asset before partition without proper authority.
Paying heirs before determining debts and estate tax.
Signing a quitclaim without an inventory, valuation, or explanation of its tax effect.
Treating an unmarried partner as a surviving spouse—or ignoring that partner’s possible co-ownership claim.
Ignoring lifetime donations that may affect legitimes.
Assuming an unprobated will transfers title.
Waiting until land is about to be sold before beginning estate settlement.

When legal help is urgent

Seek prompt advice from a Philippine lawyer experienced in succession when:

someone is hiding, destroying, or altering a will;
estate money is being withdrawn or property is being sold without authority;
an heir, child, spouse, or creditor was omitted;
the validity of a marriage, adoption, or filiation is disputed;
a compulsory heir was disinherited or completely omitted from a will;
signatures on a will, deed, waiver, or settlement may be forged;
the decedent had property abroad or was a foreign national;
there are minor, incapacitated, missing, or overseas heirs;
a Rule 74 annotation or two-year period is approaching;
tax deadlines have passed or a transfer is blocked for lack of an eCAR; or
a buyer, bank, corporation, or government office is demanding documents that the family cannot lawfully produce.

Immediate court relief may be necessary where property is at risk of dissipation. Do not sign a settlement merely to meet a buyer’s deadline when heirship or ownership remains unresolved.

Frequently asked questions

Can a parent leave everything to only one child?

Not ordinarily if other compulsory heirs survive. The favored child may receive the free portion in addition to that child’s legitime, but dispositions impairing the other compulsory heirs’ legitimes may be reduced.

Do married daughters lose inheritance rights?

No. Marriage does not remove a child’s inheritance rights or give sons priority over daughters.

Does the eldest child receive a larger share?

No general rule gives the eldest child a larger hereditary share. Legitimate children in the same degree generally inherit equally, subject to a will, representation, legitimes, and other applicable rules.

Can an illegitimate child inherit from the father?

Yes, if filiation is legally established. The child is a compulsory heir of the father, although the share and possible representation through other relatives are governed by specific rules.

Can grandchildren inherit while their parent is alive?

Ordinarily, the nearer descendant excludes the more remote descendant. Grandchildren may inherit directly under a will from the free portion or may represent a parent only in circumstances authorized by law.

Does a handwritten will count?

A holographic will may be valid if it is entirely written, dated, and signed by the testator, subject to the Civil Code’s other requirements. It must still be probated.

Can one heir sell inherited land without the others?

Before partition, an heir may generally transfer only that heir’s hereditary or undivided interest—not the entire land or another heir’s share. The buyer may acquire only what is ultimately allotted to the selling heir.

Can heirs settle an estate without going to court?

Yes, but only when Rule 74’s requirements for extrajudicial settlement are satisfied. A will, unpaid debts, disagreement, omitted heir, disputed filiation, or inadequate representation of a minor may require judicial proceedings.

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

Inheritance is subject to the decedent’s obligations, but an heir’s liability is generally limited by the value of the property received, subject to the nature of the obligation and the heir’s own separate undertakings. Estate assets should not be distributed before legitimate claims are addressed.

Does a waiver automatically give the share to a chosen sibling?

Not necessarily. The wording and timing may make the transaction a repudiation, donation, sale, partition, or compromise, each with different succession and tax consequences.
