Quick answer

Philippine law does not allow a person to leave the entire estate to anyone they choose when compulsory heirs survive. These heirs are entitled to a minimum share called a legitime. A will may control only the portion not reserved by law and cannot validly deprive a compulsory heir of a legitime unless the heir is properly disinherited for a statutory cause.

If there is no valid will—or the will does not dispose of the entire estate—the rules on intestate succession determine who inherits and in what proportions. The result depends on the complete family tree, the validity of marriages and adoptions, proof of filiation, the marital property regime, prior donations, debts, and the contents and validity of any will.

An heir’s percentage is calculated from the decedent’s net hereditary estate, not automatically from every property the decedent appeared to own.

First determine what actually belongs to the estate

Before calculating anyone’s inheritance, identify the estate correctly:

List the decedent’s real properties, bank accounts, vehicles, investments, business interests, receivables, personal property, and other transferable rights.
Verify ownership through titles, tax declarations, contracts, bank records, corporate books, and government registrations.
Determine whether each asset was exclusive property, community property, conjugal property, or co-owned with another person.
Liquidate the spouses’ property regime when applicable.
Deduct enforceable debts, estate obligations, and proper charges.
Account for lifetime donations that must be collated or considered when computing legitimes.

If an asset belonged to the absolute community or conjugal partnership, the surviving spouse’s share arising from the marital property regime is separated first. Only the portion attributable to the deceased enters the hereditary estate. The surviving spouse may then inherit from that hereditary estate as an heir. The spouse’s property-regime share and inheritance are legally distinct.

Under Articles 103 and 130 of the Family Code, community or conjugal property should be liquidated in the estate proceeding or, if there is no judicial settlement, judicially or extrajudicially within six months from death. Dispositions or encumbrances involving unliquidated community or conjugal property after that period may be void.

Rights arise at death, but settlement is still necessary

Successional rights are transmitted from the moment of death. This does not mean that one heir immediately owns a particular house, lot, vehicle, or bank account exclusively.

Before partition, the heirs generally hold the inheritance in common, subject to:

The decedent’s debts and estate expenses;
The surviving spouse’s property rights;
The validity and probate of any will;
The legitimes of compulsory heirs;
Tax and registration requirements; and
The eventual partition or court-approved distribution.

An heir cannot safely sell the whole of a specific estate property as if it were already exclusively theirs. At most, an heir may attempt to deal with their hereditary interest, subject to the rights of the estate and the other heirs. Transactions involving unpartitioned estates frequently lead to title disputes and litigation.

The heirs are not personally liable for the decedent’s obligations beyond the value of the property they receive from the inheritance.

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 legal spouse; and
Illegitimate children whose filiation is duly proved.

Legitimate parents ordinarily do not receive a legitime when legitimate children or descendants survive. The surviving spouse and duly proven illegitimate children may concur with legitimate descendants or, in the proper case, with legitimate ascendants.

A legally adopted child is treated as a legitimate child of the adopter. Section 43 of the Domestic Administrative Adoption and Alternative Child Care Act, Republic Act No. 11642, gives adopters and adoptees reciprocal succession rights without distinction from legitimate filiation. The exact effect on biological-family succession must be assessed from the adoption order, the kind and date of adoption, and any applicable testamentary rules.

Brothers, sisters, nephews, nieces, more distant relatives, unmarried partners, stepchildren who were not adopted, friends, and caregivers are not ordinarily compulsory heirs. They may nevertheless inherit under a valid will or, for qualifying relatives, through intestate succession when nearer heirs are absent.

Legitimate and illegitimate children

A child’s right does not disappear merely because the parents were unmarried. However, filiation must be established by legally admissible proof.

Article 176 of the Family Code, as amended by Republic Act No. 9255, provides that the legitime of each illegitimate child is one-half of the legitime of a legitimate child. This ratio is subject to the disposable portion of the estate and to the rights of other compulsory heirs.

Relevant proof may include:

A PSA birth certificate;
The parent’s acknowledgment in the civil register;
An admission in a public document;
A signed private handwritten instrument;
A final judgment establishing filiation; or
Other evidence allowed under the Family Code and the Rules on Evidence.

Using or not using the father’s surname does not, by itself, conclusively settle inheritance rights. Disputed filiation—especially after the parent’s death—is highly fact-sensitive and may involve restrictions on when and how an action may be brought. Legal advice should be obtained promptly.

The Supreme Court has also clarified that Article 992’s traditional “iron curtain” restriction does not apply in the same way when an illegitimate grandchild inherits by right of representation from a grandparent. The precise line of descent and the reason the intermediate heir cannot inherit remain important. See Aquino v. Aquino, G.R. No. 208912, December 7, 2021.

How a will affects inheritance

A valid will determines the distribution of the estate only within legal limits. It cannot impair compulsory heirs’ legitimes.

No will—whether notarized or handwritten—transfers property as a will unless it is proved and allowed by the proper court. This is the rule under Rule 75 of the Rules of Court, repeatedly applied by the Supreme Court. See, for example, In the Matter of the Petition to Approve the Will of Ruperta Palaganas, G.R. No. 169144.

A will may be challenged on grounds such as:

Failure to observe the required form;
Lack of testamentary capacity;
Forgery;
Undue influence, fraud, or duress;
Revocation;
Preterition;
Invalid disinheritance; or
Dispositions that impair legitimes.

The existence of a will normally requires probate even if the family agrees with its contents.

How legitimes generally work when there is a will

The following table states common patterns. It is only a starting point: representation, several classes of children, prior donations, marital-property liquidation, disinheritance, renunciation, and unusual family relationships can alter the computation.

Compulsory heirs surviving	General reserved shares
Legitimate children only	Collectively, one-half of the net hereditary estate
One legitimate child and surviving spouse	Child: one-half; spouse: one-fourth
Two or more legitimate children and surviving spouse	Children collectively receive one-half; spouse receives a share equal to the legitime of one legitimate child
Illegitimate children only	Collectively, one-half
Surviving spouse and illegitimate children only	Spouse: one-third; illegitimate children collectively: one-third
Legitimate parents or ascendants only	Collectively, one-half
Legitimate parents or ascendants and surviving spouse	Ascendants: one-half; spouse: one-fourth
Legitimate parents or ascendants and illegitimate children	Ascendants: one-half; illegitimate children collectively: one-fourth
Legitimate parents or ascendants, surviving spouse, and illegitimate children	Ascendants: one-half; spouse: one-eighth; illegitimate children collectively: one-fourth
Surviving spouse only	One-half, subject to the special deathbed-marriage rule in Article 900

When legitimate and illegitimate children concur, each illegitimate child’s legitime is generally one-half of a legitimate child’s legitime. The surviving spouse’s legitime must also be protected, and the children’s exact fractions must be fitted within the portions available under Articles 888–903 of the Civil Code.

The balance after all legitimes are satisfied is the free or disposable portion. The testator may generally give that portion to any person legally capable of inheriting.

What happens when there is no valid will?

In intestate succession, the law selects the heirs. Nearer relatives generally exclude more distant relatives, subject to representation and the special rights of the surviving spouse and illegitimate children.

Common intestate combinations include:

Survivors	General intestate distribution
Legitimate children only	Equal shares, subject to representation
Legitimate children and surviving spouse	Spouse receives the same share as each legitimate child
Legitimate and illegitimate children	Each illegitimate child generally receives one-half of the share of a legitimate child
Legitimate children, illegitimate children, and surviving spouse	Spouse generally receives the equivalent of one legitimate child’s share; each illegitimate child generally receives one-half of that unit
Legitimate parents or ascendants only	They inherit the estate under the rules on proximity and paternal and maternal lines
Legitimate parents or ascendants and surviving spouse	One-half to the ascendants and one-half to the spouse
Illegitimate children and surviving spouse	One-half to the spouse and one-half collectively to the illegitimate children
Legitimate ascendants, surviving spouse, and illegitimate children	One-half to the ascendants, one-fourth to the spouse, and one-fourth collectively to the illegitimate children
Surviving spouse with brothers, sisters, nephews, or nieces	One-half to the spouse and one-half to the qualifying collateral relatives
Surviving spouse with no descendants, ascendants, illegitimate children, siblings, nephews, or nieces	The spouse generally inherits the entire estate
No descendants, ascendants, illegitimate children, or spouse	Brothers, sisters, nephews, nieces, then other qualified collateral relatives may inherit
No qualified heir	The State inherits

Collateral intestate succession ordinarily does not extend beyond the fifth degree. Full-blood siblings generally receive twice the share of half-blood siblings when they inherit together.

These rules appear principally in Articles 960–1014 of the Civil Code.

Representation: when descendants take another heir’s place

Representation allows a qualified descendant to step into the place of an heir who would have inherited had that person been able to do so.

It generally operates:

In the direct descending line; and
In the collateral line only for children of the decedent’s brothers or sisters.

Distribution by representation is per stirpes, or by family branch. For example, if one of three children of the decedent died earlier and left two qualified children, those grandchildren generally divide the share their parent would have received.

Representation does not arise merely because an heir prefers not to inherit. An heir who repudiates an inheritance generally cannot be represented for that reason.

A compulsory heir cannot simply be omitted

Preterition

Preterition is the total omission of a compulsory heir in the direct line from the inheritance, without the heir receiving anything by will or otherwise as an advance on inheritance. Under Article 854, true preterition may annul the institution of heirs, although valid devises and legacies may remain effective to the extent permitted by law.

Not every omission is preterition. The result depends on whether the heir is in the direct line, whether the omission was total, and whether the heir received anything chargeable to the legitime. See Trinidad v. Court of Appeals, G.R. No. 254695.

Incomplete legitime

If a compulsory heir received less than the proper legitime, the heir may demand completion of that share. Excessive testamentary gifts and, when appropriate, lifetime donations may be reduced to restore impaired legitimes.

Disinheritance

Disinheritance is valid only when:

It is made in a will;
The will states a cause expressly recognized by law;
The cause applies to the particular compulsory heir; and
If the heir denies the cause, the persons relying on the disinheritance prove it.

Family estrangement, personal dislike, disapproval of a relationship, or a bare statement that a child has been “disowned” is not automatically a lawful disinheritance. Articles 915–923 of the Civil Code contain the exclusive statutory grounds and requirements.

Can an heir reject the inheritance?

Yes. An heir may accept or repudiate an inheritance, but the decision generally applies to the inheritance as a whole and is ordinarily irrevocable once validly made, except in the circumstances allowed by law.

Repudiation must be made in a public or authentic instrument or by a petition presented to the court with jurisdiction over the estate. A casual oral statement, family chat message, or failure to attend a meeting should not be treated as a legally sufficient waiver.

An heir should first understand:

The assets and debts of the estate;
The value and location of the hereditary share;
Tax consequences;
Whether the waiver benefits identified co-heirs or operates more broadly; and
Whether the transaction may be treated as a donation for tax purposes.

No one can validly waive or compromise a future legitime while the person whose estate is involved is still alive. Article 905 makes such agreements void.

Judicial or extrajudicial settlement

Extrajudicial settlement

Under Rule 74, Section 1 of the Rules of Court, heirs may settle an estate extrajudicially when, among other requirements:

The decedent left no will;
The estate has no outstanding debts, or the debts have been fully addressed;
All heirs participate;
All heirs are of age, or minors are properly represented by judicial or legal representatives;
The settlement is made in a public instrument or, for a sole heir, through an affidavit of self-adjudication;
The fact of settlement is published once a week for three consecutive weeks in a newspaper of general circulation; and
The required bond is filed when personal property is involved.

Publication does not cure the omission of a known heir. An extrajudicial settlement generally does not bind an heir who did not participate and had no notice. Rule 74 also protects creditors and omitted heirs through remedies associated with its two-year period, but that period is not a universal deadline that automatically validates fraud or extinguishes every ownership claim. The applicable remedy and prescriptive period depend on the nature of the claim.

Judicial settlement

Court proceedings are usually necessary when:

There is a will;
Heirs or creditors dispute the estate;
An heir has been omitted;
Filiation, marriage, adoption, ownership, or the validity of a transfer is contested;
The estate has unresolved debts;
No qualified person can administer the estate by agreement;
Estate property must be sold under court authority; or
Extrajudicial settlement requirements cannot be met.

An ordinary action for partition may sometimes be used when heirs recognize their co-ownership but cannot agree on division. The proper proceeding depends on whether estate administration remains necessary.

Estate tax and transfer requirements

Estate tax is separate from the heirs’ civil-law shares. For deaths covered by the TRAIN Law, the estate tax is generally 6% of the net taxable estate. The taxable estate is not necessarily the same as the amount physically divided among the heirs because tax deductions and civil-law accounting rules are not identical.

Under Republic Act No. 10963:

The estate tax return is generally due within one year from death.
A return may be required regardless of estate value when the estate includes registered or registrable property for which BIR clearance is needed.
A CPA-certified statement is generally required when the gross estate exceeds ₱5 million.
If the estate lacks sufficient cash, installment payment may be allowed within two years from the statutory payment date, subject to the law and BIR requirements.

The BIR’s current forms, documentary requirements, procedures, and filing channels should be checked on the official BIR Estate Tax page. Late filing or payment may result in surcharge, interest, and compromise penalties. Separate requirements may apply at the Registry of Deeds, local treasurer’s office, Land Transportation Office, banks, corporations, and other registries.

Do not distribute all available cash before estimating taxes, debts, publication costs, registration fees, and settlement expenses.

Practical steps for heirs

Secure the death certificate. Obtain PSA and local civil-registry copies as needed.
Look for the original will. Check the decedent’s records, safe-deposit arrangements, lawyer, and trusted family members. Do not destroy, alter, conceal, or privately “approve” it.
Prepare a complete family tree. Include all marriages, children, adopted children, predeceased children and their descendants, parents, and potentially relevant siblings.
Verify civil status and filiation. Obtain marriage certificates, birth certificates, adoption orders, acknowledgment documents, and relevant court judgments.
Inventory the estate. Include assets held solely, jointly, in trust, through businesses, or under disputed titles.
Identify the marital property regime. Review the marriage date, marriage settlements, property acquisition dates, and sources of funds.
Preserve estate property. Secure titles, vehicles, records, rental income, digital accounts, and movable assets. Record the condition of valuable property.
List debts and claims. Keep loan documents, statements, mortgages, tax records, medical bills, and receipts for funeral and estate expenses.
Obtain reliable valuations. Use appropriate records and qualified professionals where necessary.
Calculate tentative shares only after the net estate is known.
Choose the proper settlement procedure. Do not execute a deed of self-adjudication or extrajudicial settlement if a will, omitted heir, unresolved debt, or material dispute prevents its use.
Address estate tax and registration. Coordinate the BIR filing, electronic Certificate Authorizing Registration or other applicable clearance, local taxes, and registry requirements.
Partition and transfer the assets. Ensure that every affected heir signs or is properly represented and that the deed or court order is registered with each relevant agency.

Evidence to preserve

Keep originals or authenticated copies of:

The death certificate;
Any will, codicil, envelope, and related execution records;
Birth, marriage, and adoption records;
Court decisions on marriage, filiation, adoption, legal separation, or property;
Land titles, tax declarations, deeds, surveys, and property-tax receipts;
Bank, investment, insurance, pension, and loan records;
Corporate stock certificates and company records;
Vehicle registrations;
Marriage settlements and property agreements;
Proof of purchase and the source of acquisition funds;
Donation documents and records of advances to heirs;
Messages or letters acknowledging children, property, debts, or prior distributions;
Photos and video inventories of movable assets;
Receipts for funeral, preservation, tax, and administration expenses; and
Copies of every proposed or signed settlement document.

Avoid surrendering the only original of a will, title, or acknowledgment document without obtaining a detailed receipt and retaining a secure copy.

Common mistakes

Dividing the gross property without first separating the surviving spouse’s marital-property share;
Assuming that the person named on a tax declaration was the sole owner;
Treating the eldest child as automatically entitled to a larger share or sole control;
Excluding daughters, married children, children from an earlier relationship, or illegitimate children;
Assuming that a child must carry the father’s surname to inherit;
Treating a live-in partner as a surviving legal spouse;
Ignoring adopted children or descendants of a predeceased heir;
Believing that a handwritten or notarized will needs no probate;
Using self-adjudication despite the existence of other heirs;
Omitting an heir from an extrajudicial settlement and relying on publication to cure the omission;
Selling an entire estate property based on only one heir’s signature;
Signing a “waiver” without understanding whether it is a repudiation, partition, sale, or taxable donation;
Distributing cash before paying taxes and legitimate estate obligations;
Concealing estate assets, income, or records; and
Waiting until property is sold to investigate filiation, forgery, or an omitted heir.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

Someone is hiding, destroying, or altering a will;
Estate property is being sold, mortgaged, withdrawn, occupied, or transferred without all necessary authority;
A deed names a “sole heir” although other heirs exist;
A child, spouse, or descendant was omitted;
Filiation or the validity of a marriage or adoption is disputed;
A signature, acknowledgment, deed, or will may be forged;
There are competing marriages or several family branches;
The estate includes a business, substantial debt, foreign assets, agricultural land, or property covered by agrarian restrictions;
A deadline from the BIR, a court, a bank, or a registry has been received;
An heir is a minor, incapacitated, missing, or living abroad;
The family is being pressured to sign immediately; or
Violence, threats, intimidation, or removal of estate property is occurring.

Immediate remedies may include probate or administration proceedings, an action for partition or reconveyance, injunction, annotation of a notice of lis pendens where legally proper, appointment of a special administrator, or preservation and production of documents. The correct remedy depends on the facts and should not be chosen solely from a generic form.

Frequently asked questions

Does the eldest child inherit more?

No. Birth order and gender do not ordinarily give a child a larger inheritance. Children in the same legal class generally inherit equally, subject to the rules on legitimacy, representation, adoption, and the surviving spouse.

Can parents leave everything to only one child?

Not ordinarily when other compulsory heirs survive. A favored child may receive a larger amount from the free portion, but the other compulsory heirs’ legitimes must remain intact unless they were validly disinherited.

Does an illegitimate child inherit from the father?

Yes, if filiation is duly proved and the applicable legal requirements are satisfied. The child’s legitime is generally one-half of a legitimate child’s legitime.

Does a live-in partner inherit automatically?

Generally, no. An unmarried partner is not a surviving spouse or compulsory heir. The partner may own a separate or co-owned share of property and may receive property under a valid will, but co-ownership must be proved and compulsory heirs’ legitimes must be respected.

Do stepchildren inherit automatically?

No. A stepchild does not ordinarily inherit from a stepparent merely because of the marriage. The result differs if the stepchild was legally adopted or was named in a valid will.

Can grandchildren inherit while their parent is alive?

A nearer-degree child generally excludes that child’s descendants in intestate succession. Grandchildren may inherit directly under a will within legal limits or by representation when its statutory conditions exist.

Can one heir live in or collect rent from estate property?

An heir may use co-owned property only consistently with the other co-heirs’ rights. A co-heir who exclusively possesses property or collects its income may eventually have to account to the estate or co-heirs, depending on demands made, expenses paid, agreements, and the circumstances.

Does paying real-property tax make one heir the owner?

No. Tax payments may be relevant evidence of possession or administration, but they do not by themselves transfer the other heirs’ ownership.

Can an heir sell an inherited share before partition?

An heir may deal with their hereditary interest, but cannot unilaterally sell the other heirs’ shares. A buyer generally acquires only whatever interest the seller ultimately proves to have. The other co-heirs may also have statutory redemption rights in qualifying sales to a stranger.

Is a notarized extrajudicial settlement enough to transfer land?

Not by itself. The deed must satisfy Rule 74 and tax requirements, and the transfer must be registered with the Registry of Deeds. Local taxes, BIR clearance, publication, and supporting documents may also be required.

Is there one deadline for all inheritance claims?

No. Estate-tax filing, Rule 74 remedies, probate matters, annulment or rescission claims, reconveyance, partition, fraud, and recovery of property may be governed by different rules. Some ownership and partition issues are treated differently while co-ownership is expressly or impliedly recognized. Obtain advice immediately rather than assuming that a single two-, four-, or ten-year period controls.
