Quick answer

Philippine law protects an heir’s right to inherit, but the exact share depends on four things: whether there is a valid will, the heir’s legal relationship to the deceased, who else survived, and what remains after the deceased’s property regime, debts, taxes, and expenses are settled.

A person cannot freely give away the entire estate by will when there are compulsory heirs. Children, a surviving legal spouse, and—in appropriate cases—parents or other direct ascendants have reserved shares called legitimes. Children born outside a valid marriage also have inheritance rights once filiation is legally established. Legally adopted children generally inherit from their adoptive parents without distinction from legitimate filiation.

If there is no valid will, the law determines who inherits and in what proportions. The eldest child does not receive a larger share merely because of age, and daughters and sons inherit on equal terms.

What an heir actually inherits

Succession opens, and hereditary rights are transmitted, at the moment of death. The inheritance includes the deceased’s property and transmissible rights and obligations. Obligations do not become unlimited personal debts of the heirs: liability is generally limited to the value of the inheritance received.

This does not mean that each heir immediately owns a particular house, vehicle, or bank account. Before partition, two or more heirs own the hereditary estate in common, subject to payment of the deceased’s debts. An individual heir normally owns an undivided hereditary interest—not a chosen physical portion of every estate asset.

The starting figure is also not necessarily everything titled in the deceased’s name. Before shares are computed:

Determine which assets actually belonged to the deceased.
Liquidate any absolute community or conjugal partnership and separate the surviving spouse’s own share.
Resolve valid co-ownership claims, including claims arising from qualifying unions without marriage.
Pay or provide for estate debts, administration expenses, and taxes.
Add property or amounts that must be returned to the computation through collation or reduction of excessive donations.
Divide only the net hereditary estate.

These principles appear in Articles 774–781 and 1078 of the Civil Code of the Philippines.

Who may be an heir

An heir may inherit under a valid will, by operation of law when there is no effective will, or through a combination of both.

Compulsory heirs

Compulsory heirs are persons for whom the law reserves a legitime. Depending on the family situation, they include:

Legitimate children and descendants;
In their absence, legitimate parents or ascendants;
The surviving legal spouse; and
Children born outside a valid marriage whose filiation is duly proved.

A legally adopted person is considered the legitimate child of the adopter. Under Sections 41 and 43 of the Domestic Administrative Adoption and Alternative Child Care Act, the adopter and adoptee have reciprocal rights of testate and intestate succession without distinction from legitimate filiation. The adoption order, its date, and any later rescission must still be examined.

A child who was legitimated by the parents’ subsequent valid marriage has the same rights as a legitimate child, subject to the requirements in Articles 177–182 of the Family Code.

People who do not automatically inherit

The following relationships alone do not make a person a legal heir:

A live-in or common-law partner who was not legally married to the deceased;
A stepchild who was neither adopted nor named in a valid will;
A fiancé, caregiver, godchild, friend, or household member;
A sibling when a nearer class of heirs excludes siblings; or
A person named as an authorized signatory, attorney-in-fact, or property caretaker.

A surviving live-in partner may nevertheless own part of particular property under Articles 147 or 148 of the Family Code if the required cohabitation and contribution facts are proved. That is a co-ownership claim, not an automatic inheritance share.

When there is a valid will

A will controls only within the limits set by law. No will transfers real or personal property unless it is proved and allowed by the proper court. A private agreement among the family cannot substitute for probate.

The person holding the will must deliver it to the court or named executor within 20 days after learning of the testator’s death. The named executor has a corresponding 20-day duty to present the will and state whether the appointment is accepted. These requirements are in Rules 75 and 76 of the Rules of Court on special proceedings.

The will cannot impair legitimes

The deceased may dispose freely only of the legally disposable portion. The principal rules include:

Legitimate children or descendants collectively have a legitime equal to one-half of the hereditary estate, subject to the concurrent rights of the spouse and children born outside marriage.
Each child born outside marriage has a legitime equal to one-half of the legitime of a legitimate child.
The surviving spouse’s legitime varies depending on whether the spouse concurs with children, parents, or other heirs.
Legitimate parents or ascendants have a reserved share when there are no legitimate children or descendants.

Actual calculations can become complex when several classes concur. Do not apply a percentage to the gross properties without first liquidating the property regime, valuing donations, deducting enforceable obligations, and identifying every compulsory heir.

Omission is not automatically disinheritance

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

A compulsory heir may be disinherited only:

Through a valid will;
For a cause expressly recognized by law;
With the legal cause stated in the will; and
With the cause proved by those relying on the disinheritance if the heir denies it.

Family disappointment, ordinary estrangement, personal preference, or a bare statement that an heir should receive nothing is not enough by itself. Articles 915–923 provide separate statutory causes for descendants, ascendants, and spouses.

Lifetime gifts may affect the final shares

A compulsory heir who received property from the deceased by donation or another gratuitous title may have to bring its value into the estate computation through collation. Ordinary support, education, medical expenses, and customary gifts are generally treated differently. Even a donation expressly exempted from collation may be reduced if it impairs another heir’s legitime.

Keep deeds of donation, tax returns, proof of valuation, acknowledgments, and evidence showing whether the gift was intended as an advance or was exempted from collation.

When there is no valid will

Intestate succession applies when there is no will, the will is void or ineffective, the will does not dispose of the entire estate, an instituted heir cannot inherit, or another circumstance listed in Article 960 exists.

The nearest relatives generally exclude more remote relatives, except when the right of representation applies. These are common intestate outcomes:

Surviving heirs	General division of the net hereditary estate
Legitimate or legally adopted children only	Equal shares
Surviving spouse and legitimate or adopted children	The spouse receives the same share as each child
Legitimate and children born outside marriage; no spouse	Each child born outside marriage generally receives one-half of each legitimate child’s share
Spouse, legitimate children, and children born outside marriage	The spouse has the weight of one legitimate child; each child born outside marriage has one-half that weight
Children born outside marriage only, with no qualifying descendants or ascendants ahead of them	They generally divide the estate equally
Spouse and children born outside marriage only	One-half to the spouse; one-half collectively to those children
Legitimate parents or ascendants only, with no descendants	The parents or qualifying nearest ascendants inherit under the ascending-line rules
Spouse and legitimate parents or ascendants	One-half to the spouse; one-half to the parents or ascendants
Legitimate ascendants and children born outside marriage	One-half to each class
Spouse, legitimate ascendants, and children born outside marriage	One-half to the ascendants, one-fourth to the spouse, and one-fourth collectively to the children
Spouse and brothers, sisters, nephews, or nieces, with no descendants, ascendants, or children born outside marriage	One-half to the spouse and one-half to the qualifying collateral heirs
Spouse alone, with no competing heirs recognized by law	The entire estate
No spouse, descendants, ascendants, or children born outside marriage	Brothers and sisters and their qualifying descendants inherit first; more remote collateral relatives may inherit only within the limits of the Civil Code

These are general combinations, not a substitute for a family-tree computation. Representation, full- or half-blood relationships, adoption, repudiation, incapacity, legal separation, and disputed filiation may change the result. Full-blood siblings generally receive twice the share of half-blood siblings when they inherit together. In the absence of closer heirs, collateral succession does not extend beyond the fifth civil degree; the State ultimately succeeds if no qualified heir exists.

When grandchildren inherit

A grandchild does not automatically share alongside a living parent who is able and qualified to inherit. The right of representation ordinarily arises when the person through whom the grandchild claims predeceased the decedent, is incapacitated or unworthy, or in another situation expressly recognized by law.

Representation divides the inheritance per stirpes, or by family branch. The representatives together receive no more than the person represented would have received.

Representation generally does not arise merely because a living heir repudiated the inheritance. The Civil Code expressly states that heirs who repudiate their shares may not be represented.

Rights of children born outside marriage

The legal term used in the Civil and Family Codes is “illegitimate child,” but the child’s rights do not depend on blame or fault.

Article 176 of the Family Code provides that each such child’s legitime is one-half of the legitime of a legitimate child. Filiation must, however, be legally established. Relevant evidence may include:

A civil-registry birth record;
A final judgment;
An admission of filiation in a public document;
A private handwritten instrument signed by the parent;
Proof of open and continuous possession of the status of a child; and
Other evidence allowed by the Rules of Court and special laws.

The applicable evidence and filing period depend on the basis of the claim and whether the alleged parent is living. A filiation dispute after a parent’s death requires prompt legal advice.

Article 992’s former “iron curtain” interpretation has also been narrowed. In Aquino v. Aquino, the Supreme Court en banc held that a child born outside marriage may represent a predeceased parent and inherit intestate from a direct ascendant, such as a grandparent, regardless of the parent’s marital status. The child must still prove filiation and the facts supporting representation. Read the official decision in G.R. Nos. 208912 and 209018, December 7, 2021.

Article 992 may still affect reciprocal intestate succession across collateral family lines. Claims involving siblings, aunts, uncles, cousins, or nephews and nieces separated by a nonmarital line therefore need careful analysis.

Circumstances that may reduce or defeat a claim

An apparent heir may receive less or nothing because of:

A valid disinheritance;
Incapacity or unworthiness under Articles 1027–1040 of the Civil Code;
A final decree of legal separation disqualifying the offending spouse from intestate succession;
Bad faith in certain void or terminated marriages;
A valid repudiation of the inheritance;
Prior donations chargeable to the heir’s share;
A successful challenge to filiation, marriage, adoption, or the will;
The heir having predeceased the decedent without a qualified representative; or
The estate being exhausted by enforceable debts and expenses.

Repudiation is voluntary but formal. It must be made in a public or authentic instrument or through a petition in the court handling the estate. Once validly made, it is generally irrevocable. Renouncing “in favor of” selected co-heirs may legally amount to acceptance followed by a transfer and may have donor’s-tax consequences. Obtain tax advice before signing a waiver, quitclaim, deed of assignment, or extrajudicial settlement containing a targeted renunciation.

How an estate is settled

Extrajudicial settlement

An extrajudicial settlement under Rule 74 is available only when:

The deceased left no will;
There are no outstanding estate debts;
All heirs participate;
All heirs are adults, or minors are represented by duly authorized judicial or legal representatives; and
The required public instrument, publication, registration, and bond requirements are satisfied.

If there is only one heir, that heir may use an affidavit of self-adjudication when the requirements truly exist. A person must not use self-adjudication simply because the other heirs are abroad, unknown, estranged, or unwilling to sign.

The settlement must be published in a newspaper of general circulation once a week for three consecutive weeks. Publication does not cure the deliberate omission of an heir: Rule 74 states that an extrajudicial settlement is not binding on a person who did not participate or had no notice.

Rule 74 gives creditors and persons deprived of lawful participation a two-year remedy against the distributees, bond, and estate property. Minors and certain incapacitated or absent claimants receive the additional period stated in Section 5. This two-year provision should not be treated as a universal rule that automatically extinguishes every excluded heir’s ownership or every claim involving fraud, lack of notice, or an invalid settlement.

Judicial settlement

Judicial settlement is normally appropriate when:

There is a will;
The heirs disagree;
Estate debts remain unresolved;
An heir, spouse, creditor, or property is disputed;
Filiation or adoption is contested;
A minor or incapacitated heir is not properly represented;
Property must be sold under court authority;
There are allegations of concealment, forgery, undue influence, or fraud; or
No qualified person can validly complete an extrajudicial settlement.

For a Philippine resident, the proceeding is generally filed where the deceased resided or was domiciled at death. For a nonresident, it may be filed where Philippine estate property is located. Under Republic Act No. 11576, first-level courts have probate jurisdiction when the estate’s value does not exceed ₱2 million, while the Regional Trial Court has jurisdiction when the gross estate exceeds ₱2 million.

Rule 74 separately retains a summary court procedure for an estate whose gross value does not exceed ₱10,000. That old threshold is distinct from the current ₱2-million division of ordinary probate jurisdiction and should not be used without procedural advice.

Estate tax and transfer deadlines

The tax law in force on the date of death governs. For a person who died on or after January 1, 2018, the TRAIN law generally imposes estate tax at 6% of the net taxable estate.

For a Philippine citizen or resident, current deductions include a ₱5-million standard deduction and, when the statutory requirements are met, the fair market value of the family home up to ₱10 million. The surviving spouse’s net share in community or conjugal property is also excluded from the deceased’s taxable net estate. These are tax deductions, not the heirs’ civil-law shares.

An estate-tax return is required for taxable transfers and, regardless of value, when the estate contains registered or registrable property—such as land, a motor vehicle, or shares of stock—for which BIR clearance is required. For deaths covered by the current rules:

File BIR Form 1801 within one year from death.
A return showing a gross estate exceeding ₱5 million must include the statement certified by a CPA required by Section 90 of the Tax Code.
In meritorious cases, the BIR may grant an extension to file of no more than 30 days.
When estate cash is insufficient, payment by installment may be allowed within two years from the statutory payment date, subject to BIR requirements.
A separate hardship extension to pay may be granted for up to five years for a judicially settled estate or two years for an extrajudicially settled estate. Approval is not automatic.

The controlling provisions are in the TRAIN Law and BIR Revenue Regulations No. 12-2018. Current forms, requirements, and processing information are available from the BIR estate-tax page.

For inherited real property, Section 135 of the Local Government Code also states that the local transfer tax must be paid within 60 days from the decedent’s death. Local rates and documentary requirements should be confirmed with the city or provincial treasurer.

After filing and payment, obtain the applicable BIR electronic Certificate Authorizing Registration, pay the local transfer tax and other lawful charges, then register the settlement, court order, or approved partition with the Registry of Deeds and update the tax declaration.

The expanded estate-tax amnesty ended on June 14, 2025. There is no basis to assume that an old estate remains covered by that expired program. Older estates must be computed under the law applicable on the relevant date of death, including lawful penalties and any still-available remedies.

Documents and evidence to preserve

Secure originals or certified copies whenever possible:

PSA death certificate;
PSA birth and marriage certificates of all possible heirs;
Adoption, legitimation, annulment, nullity, or legal-separation orders;
The original will, codicils, envelopes, and related custody records;
Land titles, condominium titles, tax declarations, surveys, and deeds;
Vehicle records, stock certificates, brokerage statements, passbooks, and bank records;
Business records, partnership documents, receivables, and intellectual-property records;
Insurance policies and beneficiary designations;
Marriage settlements and proof of each spouse’s exclusive property;
Loan agreements, mortgages, tax liabilities, funeral receipts, and creditor correspondence;
Deeds of donation, donor’s-tax returns, and evidence of lifetime advances;
Records proving filiation, recognition, support, and continuous treatment as a child;
Medical records and witness information relevant to testamentary capacity or undue influence;
Prior extrajudicial settlements, affidavits, waivers, publication affidavits, and titles issued from them; and
Photographs, messages, emails, and transaction records showing possession, rentals, withdrawals, or attempted sales.

Do not surrender the only original will or sign a blank settlement, waiver, special power of attorney, or deed. Keep a dated digital copy and record who currently holds each original.

Practical steps for an heir

Secure the property. Preserve records, change no ownership entries without authority, and document the condition and occupants of estate assets.
Look for a will immediately. If one exists, observe the 20-day delivery rule and start probate.
Build the full family tree. Include children from every relationship, adopted or legitimated children, predeceased children and their descendants, the legal spouse, and living parents.
Verify civil status. Obtain PSA records and court or adoption orders rather than relying on family assumptions.
Prepare an inventory. List assets, co-owners, acquisition dates, estimated values, income, liens, and debts.
Separate ownership from inheritance. Determine the surviving spouse’s or partner’s own property before computing hereditary shares.
Calendar tax dates. Note the 60-day local transfer-tax deadline and one-year BIR estate-tax deadline.
Choose the proper settlement route. Use an extrajudicial settlement only if every Rule 74 condition is genuinely satisfied.
Obtain independent valuations. This is important when one heir will receive the house or business while others receive cash or different property.
Register the final transfer. A family agreement that is never processed with the BIR, local treasurer, Registry of Deeds, and other relevant registries leaves practical and legal problems unresolved.

Common mistakes

Dividing all community or conjugal property as though it entirely belonged to the deceased;
Assuming that the name on a title conclusively resolves every marital-property or co-ownership issue;
Excluding a child born outside marriage without examining filiation evidence;
Giving the eldest child a larger share without a legal basis;
Treating a live-in partner as a surviving spouse—or ignoring that partner’s possible co-ownership claim;
Using self-adjudication despite the existence of another heir;
Selling a specific estate asset based only on one heir’s signature;
Ignoring lifetime donations when calculating legitimes;
Believing newspaper publication alone binds an omitted heir;
Treating Rule 74’s two-year period as an automatic erasure of every excluded heir’s rights;
Waiting for family negotiations to finish before addressing tax deadlines;
Assuming an unprobated will transfers ownership;
Signing a “waiver” without understanding that it may be irrevocable or taxable; and
Distributing assets before debts and taxes are paid or adequately secured.

When legal help is urgent

Consult a Philippine succession lawyer promptly when:

Someone is hiding, destroying, or refusing to deliver a will;
An estate asset is being sold, mortgaged, withdrawn, or transferred without all necessary authority;
The tax deadlines are near or have passed;
A child’s filiation is disputed, especially after the alleged parent’s death;
A spouse’s marriage, legal separation, or property regime is contested;
A minor or incapacitated heir is being asked to sign or is not independently represented;
An heir was omitted from a deed, affidavit of self-adjudication, or court petition;
Signatures, notarizations, civil-registry records, or titles may be forged;
The deceased had foreign citizenship, residence, heirs, assets, or a foreign will;
Creditors are threatening foreclosure or collection;
The estate includes a business, agricultural land, corporate shares, intellectual property, or substantial debts; or
There are credible allegations of fraud, coercion, undue influence, or lack of testamentary capacity.

Qualified indigent parties may ask the Public Attorney’s Office whether they meet its legal-assistance requirements.

Frequently asked questions

Can a parent leave everything to one child?

Only to the extent allowed by the disposable portion. A will or lifetime donation that impairs another compulsory heir’s legitime may be reduced or challenged.

Can a child be disinherited for not visiting or communicating?

Not merely for that reason. Disinheritance requires a valid will and a specific statutory cause that can be proved if denied. The facts may overlap with a statutory cause in an exceptional case, but ordinary estrangement is not itself a free-standing ground.

Do children born outside marriage inherit from their father?

Yes, if filiation is legally established. Their legitime is generally one-half of that of a legitimate child. Their actual intestate share depends on the other surviving heirs.

Can such a child inherit from a grandparent?

Yes, by right of representation when the legal conditions are present, under the Supreme Court’s ruling in Aquino v. Aquino. Filiation and the represented parent’s status must still be proved.

Does a live-in partner inherit automatically?

No. A partner who was not legally married is not automatically a surviving-spouse heir. The partner may have a separate co-ownership claim or may inherit under a valid will from the disposable portion.

Can one heir sell the inherited house?

Not ordinarily as the sole owner before partition. An heir may have an undivided hereditary interest, but one heir cannot unilaterally transfer the entire house or bind the shares of the others without authority.

Are heirs required to pay the deceased’s debts from their own money?

Generally, an heir’s liability is limited to the value of the property inherited. Estate debts must be addressed before distribution, and an heir who receives estate property may be required to contribute within that limit.

Can an heir refuse an inheritance?

Yes. Repudiation must follow the required form and is generally irrevocable. A parent or guardian needs judicial authority to repudiate an inheritance for a minor or incapacitated heir.

Is an oral statement a valid will?

No. Philippine wills must comply with statutory written formalities. A handwritten holographic will and an attested notarial will have different requirements, but both must still be probated after death.

Does payment of estate tax prove that someone is the true heir?

No. Tax payment and an eCAR facilitate transfer but do not conclusively resolve disputed filiation, ownership, fraud, or the validity of a settlement. Civil-law rights must still be properly established.
