Quick answer

Philippine heirs acquire hereditary rights from the moment a person dies, but no heir automatically owns a particular house, parcel of land, bank account, or vehicle. Until the estate is partitioned, the heirs generally own the hereditary estate in common, subject first to the deceased’s valid debts, estate expenses, taxes, and the liquidation of any community or conjugal property.

The correct shares depend on several facts:

Whether there is a valid will;
Which compulsory and legal heirs survived;
Whether filiation, marriage, or adoption is legally established;
Whether a deceased child is represented by descendants;
The spouses’ property regime;
Lifetime donations that must be collated or reduced;
Any valid disinheritance, incapacity, renunciation, or special succession law; and
The law in force on the date of death.

A will cannot ordinarily deprive compulsory heirs of their legitime, the minimum portion reserved by law. If there is no valid will—or the will does not dispose of the entire estate—the Civil Code’s intestate-succession rules determine who inherits. These principles come primarily from Articles 774–1105 of the Civil Code.

Start with the net hereditary estate—not the list of properties

Inheritance shares are calculated from the hereditary estate after ownership and liabilities are properly determined. A title in the deceased’s name is important evidence, but it does not always mean that 100% of the property belongs to the estate.

The usual sequence is:

Identify the deceased’s exclusive property.
Liquidate the marriage property regime. Under absolute community or conjugal partnership, the surviving spouse’s own share is separated first. It is not an inheritance. Only the deceased spouse’s net share enters the estate.
List estate assets and transmissible rights.
Deduct valid debts, charges, and expenses allowed by law.
Account for lifetime donations subject to collation or reduction.
Compute the legitimes and other hereditary shares.
Partition the remaining net estate.

Under the Family Code, net community assets or net conjugal gains are generally divided equally unless a valid marriage settlement, waiver, or statutory forfeiture requires another result. The Code also requires liquidation after a spouse’s death; dispositions involving unliquidated community or conjugal property can create serious validity issues.

Some benefits do not necessarily form part of the ordinary estate. Life insurance proceeds, retirement or employment benefits, trust assets, and similar funds may be controlled by their governing law, contract, plan rules, or beneficiary designation. Each document must be checked before treating the benefit as inheritance.

The inheritance also includes transmissible obligations, but succession transmits obligations only up to the value of what is inherited. Heirs should not distribute all assets and ignore creditors.

Rights begin at death, but the estate remains subject to settlement

Article 777 of the Civil Code provides that successional rights are transmitted at death. Where there are several heirs, Article 1078 places the estate in co-ownership before partition, subject to the deceased’s debts.

This means:

An heir has an undivided hereditary interest, not automatic ownership of a chosen property.
One heir cannot ordinarily sell or mortgage the entire inherited property without authority from the other co-owners or the court.
A co-heir may generally transfer only the undivided interest that ultimately belongs to that heir, subject to the results of settlement and partition.
Income, rent, crops, and sale proceeds received from estate property should be documented and accounted for.
Every co-heir may normally demand partition, subject to limited statutory or testamentary restrictions.

Acceptance may be express or implied. Selling, assigning, or donating an hereditary right can amount to acceptance. Repudiation must be made in a public or authentic instrument or through the court, and acceptance or repudiation is generally irrevocable. A purported waiver made in favor of selected co-heirs may also have tax and acceptance consequences.

Who are compulsory heirs?

Compulsory heirs are persons to whom the law reserves a legitime. Depending on who survived, they include:

Legitimate or marital children and descendants;
In their default, legitimate parents and ascendants;
The surviving legal spouse; and
Illegitimate or nonmarital children.

The Civil Code uses “legitimate” and “illegitimate” as legal classifications. “Marital” and “nonmarital” are more people-first terms, but the statutory terminology still appears in official records and court decisions.

Parents and ascendants are secondary compulsory heirs: legitimate children or descendants normally exclude them. The surviving spouse and nonmarital children may concur with other compulsory heirs.

Brothers, sisters, nephews, nieces, and more distant collateral relatives are generally not compulsory heirs. They may nevertheless inherit when intestate-succession rules call them to the estate.

Children’s inheritance rights

Marital and legitimated children

Marital children inherit without distinction based on sex, age, birth order, surname, financial condition, or which marriage they came from. An eldest child does not receive a larger share merely for being the eldest.

A child validly legitimated under the Family Code enjoys the same rights as a legitimate child.

Nonmarital children

A nonmarital child is a compulsory heir of each legally established parent. Under Article 176 of the Family Code, as amended by Republic Act No. 9255, each nonmarital child’s legitime is one-half of the legitime of a marital child, subject to the Civil Code’s rules protecting the surviving spouse and limiting the total charge against the disposable portion.

Filiation must be proved. Depending on the circumstances, relevant evidence may include:

The record of birth or a final judgment;
The parent’s admission in a public document or signed private handwritten instrument;
Open and continuous possession of the status of a child; or
Other evidence allowed by the Rules of Court and special laws.

Different proof grounds carry different filing periods. An action based only on open and continuous possession of status or other secondary evidence generally must be brought during the alleged parent’s lifetime. The narrow rights of a child’s heirs to continue or institute a filiation action also carry statutory conditions and, in specified cases, a five-year period. Anyone whose parentage is disputed should obtain advice immediately rather than wait for estate settlement.

Grandchildren and representation

A grandchild does not always share equally with a surviving child of the deceased. The nearer relative generally excludes the more remote, except when representation applies—for example, when a child of the deceased died earlier and that child’s descendants take the share their parent would have received. The representatives divide that branch’s share among themselves.

In Aquino v. Aquino, the Supreme Court held that children, regardless of marital status, may inherit from a direct ascendant such as a grandparent by representing their deceased parent. The ruling concerned representation in the direct line; Article 992 may still affect succession involving collateral relatives.

Adopted children

Under Sections 41 and 43 of Republic Act No. 11642, an adoptee is considered the legitimate child of the adopter, and adopter and adoptee have reciprocal rights of testate and intestate succession without distinction from legitimate filiation. The precise effect on succession involving biological relatives depends on the adoption law, the adoption order, whether the adoption was later rescinded, and whether a will is involved.

Informal care, guardianship, use of a family surname, or treating someone as a child does not by itself create the inheritance rights of a legally adopted child.

Stepchildren and foster children

A stepchild or foster child is not automatically an heir of a stepparent or foster parent. Inheritance requires a valid adoption, a valid testamentary disposition from the disposable portion, or another legal basis.

The surviving spouse

Only a person who was legally married to the deceased is ordinarily a surviving spouse for succession purposes. Separation in fact does not by itself dissolve the marriage. A partner in a void marriage or an unmarried live-in partner is generally not a surviving spouse, although that person may have independent ownership or reimbursement claims under Articles 147 or 148 of the Family Code.

A spouse who gave cause for a judicial decree of legal separation may be disqualified from intestate inheritance. The decree, its findings, reconciliation, and the applicable Civil Code and Family Code provisions must be examined.

The surviving spouse may have two distinct interests:

The spouse’s own share after liquidation of community or conjugal property; and
The spouse’s hereditary share from the deceased spouse’s estate.

Combining these two amounts and calling both “inheritance” produces incorrect computations.

If there is a will

A will does not transfer property until it has been proved and allowed by the proper court. Rule 75 of the Rules of Court on settlement of estates states that no will passes real or personal property without probate.

A person holding the will must deliver it to the proper court or named executor within 20 days after learning of the testator’s death. A named executor must ordinarily present it to the court and accept or refuse the trust within the applicable 20-day period.

The legitime limits what a will can give away

Common baseline rules include:

Marital children and descendants collectively reserve one-half of the hereditary estate.
In their absence, legitimate parents or ascendants generally reserve one-half.
A lone surviving spouse generally has a legitime of one-half when no other compulsory heir survives, subject to the special rule for certain deathbed marriages.
One marital child concurring with a spouse generally has a one-half legitime, while the spouse has one-fourth.
With two or more marital children, the spouse’s legitime is ordinarily equal to the legitime of one child.
Nonmarital children receive the legitime provided by Article 176, but their shares come from the disposable portion, and the surviving spouse’s legitime is first protected.
A spouse concurring only with nonmarital children ordinarily has a one-third legitime; the nonmarital children collectively receive another third.
Legitimate ascendants concurring with a spouse ordinarily receive one-half, while the spouse receives one-fourth.
Legitimate ascendants, a spouse, and nonmarital children may receive, respectively, one-half, one-eighth, and one-fourth, leaving one-eighth disposable.

These are starting points, not a substitute for a complete computation. Representation, lifetime donations, multiple children, repudiation, incapacity, reserva troncal, or special testamentary provisions can change the result.

An impaired legitime can be restored

A compulsory heir who received less than the required legitime may demand completion. Excessive testamentary gifts and donations may be reduced to the extent necessary to restore legitimes. Gifts made during the deceased’s lifetime must therefore be disclosed; simply transferring property before death does not necessarily defeat compulsory heirs.

Preterition is not the same as receiving too little

Preterition is the complete omission of a compulsory heir in the direct line, without that heir receiving anything by will or qualifying lifetime advance. Under Article 854, it annuls the institution of heirs, while valid devises and legacies may remain effective insofar as they do not impair legitimes. It does not invariably invalidate every part of the will. The Supreme Court discussed these limits in Trinidad v. Trinidad.

Disinheritance requires strict compliance

A parent cannot disinherit a child merely by saying “I leave nothing to this child.” Disinheritance must:

Be made in a valid will;
Identify a statutory cause applicable to that type of compulsory heir; and
Be proved by the other heirs if the disinherited heir denies the cause.

Reconciliation may erase the right to disinherit or make an earlier disinheritance ineffective. An ineffective disinheritance does not eliminate the heir’s legitime.

Separate from disinheritance, the Civil Code recognizes incapacity or unworthiness to succeed for specified serious acts. These grounds are also strictly applied and ordinarily require evidence and timely court action.

If there is no valid will

Intestate succession applies when there is no will, when the will is void or ineffective, or to property not validly disposed of by the will.

The general order is:

Children and descendants;
Parents and ascendants where applicable;
Nonmarital children and their descendants;
The surviving spouse, who may concur with the preceding groups;
Brothers, sisters, nephews, and nieces;
Other collateral relatives up to the fifth civil degree; and
The State.

This is not a simple “first group takes everything” list because the spouse and nonmarital children may concur with other classes.

Common intestate combinations

Surviving heirs	General division of the net hereditary estate
Marital children only	Entire estate divided equally, subject to representation
Spouse and marital children only	Spouse receives the same share as each child
One spouse and one marital child only	One-half each
Nonmarital children only, with no descendants, ascendants, or spouse having a better or concurrent right	Entire estate divided among them
Spouse and nonmarital children only	One-half to the spouse; one-half collectively to the children
Legitimate parents or ascendants only, with no descendants	Entire estate under the rules on proximity and paternal/maternal lines
Spouse and legitimate ascendants	One-half to the spouse; one-half to the ascendants
Legitimate ascendants and nonmarital children	One-half to each class
Spouse, legitimate ascendants, and nonmarital children	One-half to ascendants; one-fourth to spouse; one-fourth to nonmarital children
Spouse and siblings or children of siblings, with no descendants, ascendants, or nonmarital children	One-half to spouse; one-half to siblings or their qualified descendants
Spouse alone, with no qualified siblings, nephews, or nieces and no closer heirs	Entire estate
Brothers and sisters only	Governed by full-blood, half-blood, per-capita, and representation rules
No closer heirs	Other collateral relatives up to the fifth degree, then the State

Where marital children, nonmarital children, and a spouse all concur, do not apply a 2:2:1 ratio mechanically. Legitimes must be preserved first. In Macalinao v. Macalinao, the Supreme Court held that where the survivors were one legal spouse, one marital child, and two nonmarital children, the shares were one-fourth, one-half, and one-eighth for each nonmarital child. The Court explained how to protect legitimes before distributing any excess under intestate proportions.

Special situations that may change the ordinary rules

The general Civil Code framework may not control every estate:

Succession of a Filipino Muslim may fall under the Code of Muslim Personal Laws.
Under Article 16 of the Civil Code, the order and amount of succession and the intrinsic validity of testamentary provisions are generally governed by the deceased person’s national law. A foreign-national decedent or overseas property requires conflict-of-laws advice.
Indigenous community property or ancestral-domain interests may involve collective or customary-law restrictions.
Foreign wills may need allowance in the Philippines before affecting Philippine property.
Successive deaths involving property still titled to a grandparent may require a separate settlement and tax determination for every deceased owner in the chain.

How an estate may be settled

Probate or judicial settlement

Court proceedings are generally necessary when:

There is a will to probate;
The will is contested, lost, or allegedly invalid;
Heirs disagree about identity, shares, ownership, or partition;
There are unpaid debts requiring administration;
An heir has been excluded or assets concealed;
A representative must manage or sell estate property under court authority; or
An extrajudicial settlement cannot validly protect minors or incapacitated persons.

Venue ordinarily lies in the Regional Trial Court for the place where the deceased resided at death, subject to the Rules of Court and jurisdictional legislation.

Extrajudicial settlement

Rule 74 permits extrajudicial settlement when:

The deceased left no will;
There are no outstanding debts, subject to the rule’s presumption after two years;
All heirs are adults, or minors are properly represented by authorized legal or judicial representatives; and
The heirs can agree on the settlement.

The agreement must be in a public instrument. If there is only one heir, that heir may use an affidavit of self-adjudication. The settlement must be published in a newspaper of general circulation in the required manner—generally once a week for three consecutive weeks—and filed where required. A bond equivalent to the value of personal property covered by the rule may also be required.

Publication does not cure the deliberate or mistaken exclusion of an heir. Rule 74 expressly states that an extrajudicial settlement does not bind a person who did not participate or had no notice. The Supreme Court has repeatedly applied that protection, including in Treyes v. Antonio.

Rule 74 provides a two-year remedy against distributees, bonds, or property for certain unpaid claims or persons deprived of participation, with a limited additional period for specified disabilities. But the two-year period is not a universal limitation for every excluded-heir or fraudulent-settlement case. Prescription depends on participation, notice, fraud, possession, registration, trust principles, and the relief sought. Do not assume that a claim is already barred—or that it can safely wait—without legal analysis.

Estate tax and transfer requirements

Inheritance rights and estate tax are separate issues. Paying estate tax does not decide who the heirs are, and signing a settlement does not eliminate the tax requirements.

For deaths on or after January 1, 2018, the TRAIN Law generally imposes estate tax at 6% of the net taxable estate. The estate tax return is generally due within one year from death. A reasonable filing extension of up to 30 days may be granted in meritorious cases. Where immediate payment would cause undue hardship, approved payment extensions may reach five years for judicial settlement or two years for extrajudicial settlement. Approved installment payment may also be available when estate cash is insufficient. See Republic Act No. 10963, Revenue Regulations No. 12-2018, and the BIR’s estate-tax guidance.

The return is required where the transfer is taxable and where registered or registrable property requires BIR clearance. A return showing a gross estate exceeding ₱5 million must be supported by the certified statement required from an independent CPA. The applicable tax rate, deductions, valuation rules, and forms depend on the date of death.

The general estate-tax amnesty filing window has closed. For estates that timely availed of it, BIR Revenue Memorandum Circular No. 33-2026 clarifies that there is no deadline to submit proof of estate settlement, but the proof is required before an electronic Certificate Authorizing Registration, or eCAR, can be issued. It also addresses undeclared properties and approved installment arrangements. This does not reopen the amnesty to new applicants.

After tax compliance and issuance of the proper eCAR, heirs must still complete the requirements of the Registry of Deeds, assessor, bank, corporation, Land Transportation Office, or other institution holding or registering each asset.

Practical steps for an heir

Secure the death certificate and several certified copies.
Locate and protect every original will. Do not alter, staple, annotate, conceal, or destroy it.
Prepare a complete family tree, including deceased children and their descendants, children from other relationships, adopted children, prior spouses, and any judicial legal-separation or nullity cases.
Obtain civil-registry records proving birth, marriage, death, adoption, legitimation, and acknowledged filiation.
Inventory assets and liabilities as of the date of death.
Identify the marriage property regime and obtain the marriage certificate and any registered marriage settlement.
Collect records of lifetime donations, advances, transfers for inadequate consideration, and property placed in another person’s name.
Preserve and account for estate income. Record rent, crops, business receipts, withdrawals, dividends, and expenses after death.
Check titles and registrations for recent sales, mortgages, annotations, adverse claims, and tax declarations.
Determine the proper settlement route before signing a deed or affidavit.
Compute succession and tax consequences together with qualified legal and tax professionals.
Obtain the eCAR and complete asset-specific transfers only after the settlement documents are legally consistent.

Evidence worth preserving

Keep originals and reliable electronic copies of:

Wills, codicils, envelopes, and communications about their custody;
PSA and local civil-registry certificates;
Adoption and legitimation orders;
Documents acknowledging filiation;
Land titles, tax declarations, deeds, surveys, and property-tax receipts;
Bank, investment, insurance, pension, and loan records;
Stock certificates, corporate records, and business books;
Vehicle registrations;
Marriage settlements and property inventories;
Receipts for medical, funeral, preservation, tax, and administration expenses;
Donation records and proof of who paid for property;
Leases, crop records, rent collections, and post-death withdrawals;
Extrajudicial-settlement drafts, notices, publication affidavits, and proofs of delivery;
Messages showing agreement, exclusion, concealment, threats, or admissions; and
Evidence of possession and improvements made to estate property.

Do not remove original records from shared custody without making an inventory and giving the other interested parties a record of what was taken.

Common mistakes

Dividing the gross property without first liquidating community or conjugal ownership.
Assuming the person named on a title was the sole beneficial owner.
Treating the surviving spouse’s own one-half share as inheritance.
Excluding a nonmarital or adopted child.
Assuming a child who uses another surname cannot inherit.
Using an affidavit of self-adjudication when another heir exists.
Believing newspaper publication makes an incomplete settlement valid.
Selling a specific estate property as though one heir already owned it exclusively.
Hiding debts, lifetime donations, rentals, or bank withdrawals.
Ignoring a will because all family members prefer intestacy.
Signing a “waiver” without understanding acceptance, donor’s tax, capital-gains tax, or irrevocability.
Assuming a live-in partner is automatically a spouse—or assuming that partner has no independent property claim.
Treating the Rule 74 two-year period as the deadline for every inheritance case.
Settling only the latest death when the title still belongs to an earlier deceased owner.
Waiting until a sale is scheduled before investigating filiation or fraud.
Assuming estate-tax amnesty remains open.

When legal help is urgent

Seek a Philippine succession lawyer promptly if:

A will is being hidden, altered, or withheld;
The 20-day will-delivery period is running;
A property is about to be sold, mortgaged, demolished, or transferred;
Someone used an affidavit falsely claiming to be the sole heir;
An heir was omitted from a deed, court petition, or publication;
Filiation is disputed or the alleged parent has died or is seriously ill;
A minor or incapacitated heir is involved;
Estate money is being withdrawn without an accounting;
Signatures were forged or obtained through pressure;
A Rule 74 settlement is approaching or has passed its two-year mark;
The one-year estate-tax filing period is close or already missed;
There are foreign heirs, foreign property, a foreign decedent, or a foreign will;
Muslim personal law may apply; or
Several generations of estates remain unsettled.

Early action may permit preservation orders, proper estate administration, timely tax relief, and protection against transfers to third parties. The appropriate remedy and deadline depend on the documents and facts.

Frequently asked questions

Can a parent leave everything to only one child?

Not if other compulsory heirs survive and their legitimes would be impaired. The favored child may receive that child’s legitime plus available disposable property, but excessive gifts can be reduced.

Does a nonmarital child inherit from the father?

Yes, if filiation is legally established. The child is a compulsory heir, although the statutory legitime is generally one-half of a marital child’s legitime.

Can a nonmarital grandchild inherit from a grandparent?

Yes, when the grandchild validly represents a deceased parent in the direct line, subject to proof of filiation and the other requirements for representation.

Does an adopted child receive the same share as a biological marital child?

A validly adopted child is treated as the adopter’s legitimate child for succession. The adoption order, governing adoption law, and any rescission must still be checked.

Does a live-in partner inherit automatically?

Generally no, because an unmarried partner is not a surviving spouse. The partner may inherit under a valid will from the disposable portion or may prove a separate co-ownership or reimbursement claim.

Can an heir waive an inheritance?

An heir may repudiate after the deceased’s death through the formal method required by law. A waiver of a future inheritance while the owner is still alive is generally void. A waiver favoring particular persons can be treated differently from a pure repudiation.

Can one heir sell inherited land without the others?

One heir generally cannot sell the whole property. Before partition, the heir may at most transfer the undivided interest that ultimately belongs to that heir, subject to estate debts, taxes, partition, and the rights of co-heirs.

Do inherited debts become the heirs’ personal debts?

Succession transmits obligations only to the extent of the value inherited. Heirs should nevertheless avoid distributing estate assets before valid liabilities are settled.

Is an extrajudicial settlement always faster?

Only when its legal conditions are met and all necessary heirs cooperate. An incomplete or false settlement may cause years of litigation and make later transfers harder.

Does paying estate tax prove ownership?

No. It is tax compliance, not a judicial determination of heirship, ownership, or the validity of a partition.
