Quick answer

In the Philippines, inheritance rights arise at the moment of death, but an heir does not automatically become the exclusive owner of a particular house, lot, bank account, or other asset. The estate must first be identified, the deceased’s share in any community or conjugal property determined, valid debts and taxes paid, and the remaining estate distributed according to a valid will or—if there is no effective will—the rules on intestate succession.

Certain close family members are compulsory heirs. They are entitled to a reserved portion called the legitime, which generally cannot be taken away by a will, donation, or informal family arrangement. The exact heirs and shares depend on the family tree, the validity of the marriage and will, proof of filiation or adoption, the property regime of the spouses, prior donations, debts, and whether any heir predeceased, renounced, or was legally disqualified.

When inheritance rights begin

Under Articles 776 and 777 of the Civil Code:

The inheritance includes the deceased’s property, transmissible rights, and obligations that were not extinguished by death.
Successional rights are transmitted from the moment of death.
An heir may nevertheless accept or repudiate the inheritance, subject to legal requirements.
What ultimately passes to the heirs is the net estate, not necessarily everything registered in the deceased’s name and not property that actually belongs to another person.

Death does not erase mortgages, valid debts, unpaid taxes, or another person’s ownership. Likewise, heirs ordinarily answer for estate obligations only to the extent of what they inherit; they should not casually sign documents converting an estate obligation into their personal debt.

A surviving spouse does not automatically inherit the entire property

Before calculating inheritance, determine what the deceased actually owned.

If an asset belonged to the spouses’ absolute community or conjugal partnership, the property regime must first be liquidated. The surviving spouse’s own share is separated from the deceased’s share. Only the deceased’s net share enters the estate.

For example, a surviving spouse may receive:

Their own share following liquidation of the marital property regime; and
A separate inheritance from the deceased’s net estate.

A title bearing only one spouse’s name does not always settle whether the property was exclusive or marital. The acquisition date, source of funds, marriage date, marriage settlements, and applicable property regime may matter.

Who are compulsory heirs?

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

Legitimate children and descendants;
In their absence, legitimate parents and ascendants;
The surviving spouse; and
Illegitimate children whose filiation is duly established.

A legally adopted child generally has the rights of a legitimate child of the adopter under the Domestic Administrative Adoption and Alternative Child Care Act. The adoption decree and its terms must still be examined, especially in older or unusual cases.

“Compulsory heir” does not mean that every relative always inherits. Nearer relatives may exclude more remote relatives, and some heirs inherit only when a closer class is absent. The surviving spouse and duly established children can inherit concurrently.

What is a legitime?

A legitime is the portion of the estate that the law reserves for compulsory heirs. A testator may generally dispose by will only of the free portion remaining after all legitimes are protected.

Common testamentary-succession rules include:

Legitimate children collectively receive one-half of the hereditary estate as their legitime.
An illegitimate child’s legitime is generally one-half of the legitime of a legitimate child.
A surviving spouse who concurs with legitimate children receives a legitime equal to the legitime of one legitimate child.
Legitimate parents or ascendants have a legitime when there are no legitimate children or descendants.
The surviving spouse’s share changes depending on which other compulsory heirs survive.

These rules interact with one another. The estate should not be divided using a single percentage copied from an unrelated example.

Under Articles 904 and 906, a testator cannot deprive a compulsory heir of the legitime except through a legally valid disinheritance. A compulsory heir who receives less than the correct legitime may demand completion of the deficiency.

If there is a will

A will controls only insofar as it is valid and does not unlawfully impair compulsory heirs’ legitimes.

A will ordinarily must undergo probate, the court proceeding that determines whether it was executed with the formalities required by law and is the deceased’s valid last will. Family members should not disregard a will merely because they dislike its provisions or believe that an informal division would be faster.

A will may:

Name heirs;
Give particular property or amounts as devises or legacies;
Appoint an executor;
Direct how the free portion will be distributed; and
Impose lawful conditions that do not burden a compulsory heir’s legitime.

Probate does not automatically establish that every property listed in the will belonged entirely to the deceased. Ownership disputes and the liquidation of marital property may still require separate determination.

Omitted compulsory heirs

Leaving a compulsory heir out of a will does not always have the same effect.

Preterition generally concerns the total omission of a compulsory heir in the direct line under the conditions stated in Article 854. It can annul the institution of heirs, while valid devises and legacies may remain effective insofar as they are not excessive.
If an heir received something but less than the legitime, the usual remedy is completion of the legitime.
If the will expressly disinherits an heir, the disinheritance is valid only if the strict legal requirements are met.

Because the consequences differ, the will, family records, and prior transfers must be reviewed together.

Can a parent disinherit a child?

Not merely because of estrangement, disapproval, a family quarrel, or a verbal declaration.

A valid disinheritance must generally:

Be made in a valid will;
Identify a cause expressly recognized by law;
State that cause in the will; and
Be supported by proof if the disinherited heir denies the cause.

The Civil Code supplies specific grounds for disinheriting children and descendants, parents and ascendants, or a spouse. Those lists are strictly applied. Reconciliation may also deprive a prior disinheritance of effect.

A statement such as “I no longer consider you my child” does not by itself cancel a legally protected legitime.

If there is no valid will

Intestate succession applies when a person dies without a will, the will is void or ineffective, the will does not cover the whole estate, or another situation under Article 960 exists.

The principal order is broadly:

Children and descendants;
In their absence, parents and ascendants;
The surviving spouse and legally qualified illegitimate children, who may inherit alone or together with other classes as the Civil Code provides;
Brothers, sisters, nephews, nieces, and other collateral relatives within the degree allowed by law; and
The State, if there is no legally qualified heir.

This is only a framework. Actual shares depend on which classes concur.

Common intestate combinations

Subject to proof of status and any applicable exception:

Surviving spouse and legitimate children: the spouse generally receives the same share as each legitimate child.
Legitimate and illegitimate children: each illegitimate child generally receives one-half of the share of each legitimate child.
Spouse, legitimate children, and illegitimate children: the spouse generally takes the same share as one legitimate child, while each illegitimate child takes one-half of a legitimate child’s share.
Spouse and illegitimate children, with no legitimate descendants or legitimate ascendants: one-half generally goes to the spouse and one-half collectively to the illegitimate children.
Spouse and legitimate parents, with no descendants: one-half generally goes to the spouse and one-half to the legitimate parents.
Spouse alone: the surviving spouse may inherit the entire intestate estate if there are no descendants, ascendants, qualified illegitimate children, or siblings and their qualified children who concur under the applicable provisions.

Even a straightforward-looking family may involve different results if a child died earlier, an heir repudiated the inheritance, the deceased had children from different relationships, or filiation is disputed.

Legitimate and illegitimate children

A duly established illegitimate child has inheritance rights from their parents and is a compulsory heir of a parent. The child’s intestate share is generally one-half of a legitimate child’s share.

Filiation must be proved through evidence recognized by law. Depending on the circumstances, relevant evidence may include:

A civil-registry birth record;
A record of admission or acknowledgment;
A final court judgment;
Open and continuous possession of the status of a child; or
Other evidence allowed by the Family Code and procedural rules.

A surname, baptismal certificate, photograph, remittance, or family reputation may be relevant but is not automatically conclusive. The applicable action and deadline can depend on the kind of proof available and whether the alleged parent is alive.

Article 992 still restricts certain reciprocal intestate succession across legitimate and illegitimate family lines. However, the Supreme Court held in Aquino v. Aquino that a child whose parents did not marry may inherit from a grandparent by right of representation, regardless of the grandparent’s marital status at the birth of the child’s parent. The ruling concerns succession in the direct line and should not be generalized to every collateral-relative dispute. See Aquino v. Aquino, G.R. Nos. 208912 and 209018, December 7, 2021.

Representation when an heir dies before the decedent

Representation allows a qualified descendant to step into the place of a person who could not inherit, in the situations permitted by law.

A common example is when a child dies before a parent. The deceased child’s own qualified children may inherit the share that would have gone to that child. They divide by branch or stirps, rather than each automatically receiving a share equal to the surviving children of the decedent.

Representation does not arise in every case of renunciation, incapacity, or disinheritance. The reason the intermediate heir cannot inherit, the line of relationship, and the governing Civil Code provision must be checked.

Brothers, sisters, nephews, and nieces

Siblings are not compulsory heirs merely because they are close relatives. They ordinarily inherit by intestacy only when the deceased leaves no descendants, ascendants, surviving spouse, or other heirs who exclude them under the applicable rules.

Full-blood and half-blood siblings may receive different proportions. A nephew or niece may sometimes represent a predeceased sibling, but the result depends on whether they concur with surviving siblings and whether the legal conditions for representation are present.

A brother, sister, nephew, or niece therefore should not assume ownership merely because the deceased had no children.

Cohabiting partners and second families

An unmarried partner is not a compulsory heir and does not acquire the inheritance rights of a lawful spouse simply because the couple lived together for many years.

The partner may nevertheless have:

Ownership rights in property acquired through their actual contribution;
A claim based on the property rules applicable to unions without marriage;
Rights under a valid will, subject to the legitimes of compulsory heirs; or
Contractual or beneficiary rights outside the estate.

A person who married the deceased while a prior marriage remained valid may not qualify as a surviving spouse. Good faith, the validity or prior dissolution of marriages, and property relations can require judicial determination.

Children do not lose their rights against a parent merely because their parents were unmarried, but filiation must be established as required by law.

Donations made before death

Giving property away while alive does not necessarily defeat the heirs’ legitimes.

Donations to compulsory heirs may have to be brought into collation when computing shares. Donations to any person may be reduced if they are inofficious—that is, if they exceed what the donor could lawfully have disposed of by will.

Preserve deeds of donation, tax declarations, titles, bank records, appraisals, and evidence of who paid for the property. The date, value, recipient, and wording of each transfer can affect the calculation.

A simulated sale may also be challenged if evidence shows that it was actually a donation or that the deceased never intended a genuine transfer. Such a claim requires proof; a low price or family suspicion alone does not automatically void a deed.

Acceptance and renunciation

Acceptance may be express or may be inferred from acts that necessarily show an intention to accept. Purely preservative or administrative acts do not always amount to acceptance.

Renunciation must comply with the formalities in Article 1051: it must be made in a public or authentic instrument, or in a petition presented to the court handling the estate. A private family note may be insufficient.

An heir should obtain advice before renouncing. A renunciation can affect the heir’s descendants, co-heirs, creditors, taxes, and the operation of accretion or intestate succession. An agreement waiving a future inheritance while the owner is still alive is generally ineffective because no succession has yet opened.

How an estate is settled

Extrajudicial settlement

Under Rule 74, an estate may generally be settled without ordinary administration proceedings when:

The deceased left no will;
The estate has no outstanding debts;
All heirs participate;
All heirs are of age, or minors are properly represented; and
The required public instrument or sole-heir affidavit, publication, bond, tax, and registration requirements are satisfied.

The settlement must be published once a week for three consecutive weeks in a newspaper of general circulation. Publication does not cure failure to include a known heir, and it is not a substitute for that heir’s consent.

Rule 74 also preserves remedies for creditors and heirs who were not parties or had no notice. Its two-year protection provisions are important, but they do not authorize concealment or automatically eliminate every claim after two years. Fraud, lack of participation, incapacity, and other facts may affect the available remedy and prescriptive period.

Judicial settlement

Court proceedings are commonly necessary when:

There is a will to probate;
The heirs or their shares are disputed;
A minor or incapacitated person is not properly represented;
Filiation, marriage, adoption, ownership, or the validity of a deed is contested;
There are unpaid debts requiring administration;
An heir is missing or refuses to cooperate;
Estate assets are being concealed or dissipated; or
The parties cannot agree on partition.

The proper proceeding, court, and venue depend on the facts and the value and location of the estate.

Estate tax and transfer requirements

For deaths covered by the TRAIN law, the estate tax is generally 6% of the net taxable estate, after allowable deductions. This tax rate is not the same as an heir’s inheritance share.

An estate tax return is generally required when the transfer is taxable or when the estate contains registered or registrable property requiring BIR clearance. The statutory filing period is one year from death. Returns showing a gross estate exceeding ₱5 million require the statement prescribed by law to be certified by a CPA.

The law allows installment payment within the applicable period when the estate lacks sufficient cash, subject to the governing requirements. Late filing or payment can result in additions to the tax.

The TRAIN law provides, among other deductions, a ₱5 million standard deduction for the estate of a citizen or resident and a family-home deduction of up to ₱10 million, subject to statutory conditions. The actual computation depends on the date of death, citizenship or residence, property characterization, substantiated claims, and other deductions.

Do not rely on a current tax rule for a death that occurred years earlier. Estate-tax law is generally determined by the law in force at the time of death, although a later estate-tax amnesty may apply if its statutory requirements and deadlines are met.

Official starting points include the TRAIN Law, Republic Act No. 10963 and the Bureau of Internal Revenue.

Practical steps for heirs

Secure the death certificate. Obtain certified civil-registry copies and verify names, dates, civil status, and identifying details.
Locate the original will. Do not destroy, conceal, alter, or privately “cancel” it. Ask relatives, the named executor, and the deceased’s lawyer or document custodian.
Build a complete family tree. Include all marriages, children, adopted children, children born outside marriage, predeceased relatives, and descendants who may represent them.
Identify the deceased’s property and actual ownership share. Review titles, deeds, tax declarations, vehicle registrations, corporate records, passbooks, digital accounts, insurance policies, loan records, and marital-property documents.
Separate estate property from third-party property. Do not assume that every asset in the family home or every account used by the deceased belonged entirely to the deceased.
List debts and estate expenses. Preserve loan agreements, mortgages, receipts, medical bills, funeral expenses, notices from creditors, and proof of payment.
Secure the assets. Photograph valuable items, prepare an inventory, preserve electronic records, notify institutions where appropriate, and prevent unauthorized withdrawals or transfers.
Determine whether probate or judicial administration is necessary. Do this before signing an extrajudicial settlement.
Calculate marital shares, legitimes, prior donations, and taxes. Use documents and verified valuations rather than an informal percentage agreed upon at a family meeting.
File and pay estate tax on time. Obtain the applicable BIR clearance or electronic certificate authorizing registration before transferring registered assets.
Execute and register the proper settlement or partition documents. For land, coordinate with the Registry of Deeds, assessor, treasurer, and other agencies whose requirements apply.
Keep a complete accounting. Any person controlling estate funds should record every receipt, withdrawal, expense, rental payment, and distribution.

Evidence worth preserving

Keep originals or authenticated copies of:

Death, birth, marriage, and adoption records;
The original will and codicils;
Land titles, deeds, tax declarations, surveys, and leases;
Marriage settlements and proof of when and how property was acquired;
Bank, investment, insurance, pension, and corporate records;
Loan, mortgage, and creditor documents;
Deeds of sale or donation and proof of payment;
Messages or letters concerning acknowledgment of a child or ownership;
Medical records relevant to testamentary capacity, when genuinely disputed;
Inventories, photographs, appraisals, and receipts;
Estate-tax returns, payment confirmations, and BIR clearances; and
Every settlement, waiver, partition, authority, and acknowledgment of receipt.

Preserve the original electronic files and their metadata where possible. Do not edit screenshots or discard envelopes, signatures, notarization details, or transmission records.

Common mistakes

Dividing the whole property without first separating the surviving spouse’s ownership share;
Treating the gross estate as the amount available for inheritance;
Assuming the eldest child controls the estate;
Excluding a child born outside marriage without examining proof of filiation;
Treating an unmarried partner as a lawful spouse—or ignoring the partner’s possible co-ownership claim;
Selling inherited land before the estate is properly settled and taxes cleared;
Using an affidavit of self-adjudication when other heirs exist;
Publishing an extrajudicial settlement while concealing a known heir;
Signing a quitclaim or waiver without an inventory and share computation;
Assuming a will may freely give away property reserved as legitimes;
Believing that paying real-property tax creates ownership;
Withdrawing or using estate funds without authority and accounting;
Applying today’s tax law to an old death; and
Waiting until titles, records, witnesses, or estate assets disappear.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

Someone is selling, mortgaging, withdrawing, or transferring estate assets without the other heirs’ authority;
A will is missing, damaged, concealed, or suspected to be forged;
There is a deadline for an estate-tax return, court filing, appeal, or response;
An heir was excluded from a settlement or title;
Filiation, adoption, marriage validity, or citizenship is disputed;
A minor, incapacitated heir, absentee, or person abroad is involved;
The deceased had property or heirs in another country;
There are competing spouses or families;
A deed signed shortly before death is challenged;
Estate debts exceed or may exceed the assets;
Co-heirs cannot agree on possession, sale, rent, or partition; or
Violence, coercion, document destruction, or asset concealment is occurring.

Ask about immediate protective measures when property is at risk. Depending on the facts, relief may include probate or administration proceedings, an inventory and accounting, annotation of a claim, recovery of estate property, partition, or an injunction.

Frequently asked questions

Does the eldest child receive a larger share?

No. Birth order ordinarily does not increase an heir’s share. A larger entitlement must come from a valid legal basis, such as a permissible provision in a will, ownership independent of inheritance, or another applicable rule.

Can a parent leave everything to only one child?

Usually not if other compulsory heirs survive. The favored child may receive the free portion in addition to their legitime, but dispositions that impair other legitimes may be reduced.

Can an illegitimate child inherit from a parent?

Yes, if filiation is duly established. The child is a compulsory heir of the parent, although the share and possible representation issues depend on which other heirs survive.

Does a grandchild inherit automatically?

Not always. A grandchild commonly inherits by representation when the parent through whom the grandchild claims predeceased the decedent or another legally recognized ground exists. A grandchild may also inherit directly under a will or when nearer descendants do not exclude them under the governing rule.

Does a live-in partner inherit automatically?

No. An unmarried partner does not obtain the compulsory-heir status of a lawful spouse. The partner may still have independent ownership, contractual, beneficiary, or testamentary rights.

Can heirs divide property verbally?

A verbal understanding is unsafe and may be legally insufficient, especially for land, renunciation, or transactions requiring a public instrument and registration. Use the form required by law and ensure that every heir is properly included or represented.

Can one heir sell a specific inherited property?

Before partition, heirs generally hold the estate in co-ownership, subject to estate settlement. A co-heir may transfer only the rights they legally possess, not unilaterally convey the other heirs’ shares or guarantee ownership of a specific portion that has not been validly allotted.

What if one heir refuses to sign?

The other heirs cannot forge consent or pretend the heir does not exist. They may negotiate a lawful partition or seek judicial settlement or partition.

Is there inheritance tax separate from estate tax?

The national tax imposed upon death is the estate tax. Other costs may still arise, including local transfer taxes, registration fees, publication expenses, professional fees, and taxes connected with a later sale.

Where can the controlling rules be checked?

The primary starting points are the Civil Code of the Philippines, the applicable Rules of Court published by the Supreme Court, current tax laws, and official BIR issuances. Judicial decisions interpreting these rules form part of the Philippine legal system.
