Quick answer

Philippine law gives an heir a right only to the net estate left after identifying the decedent’s property, liquidating the applicable marital property regime, and paying enforceable debts, taxes, and settlement expenses. The amount depends on whether there is a valid will, the heir’s legal relationship to the decedent, who else survived, whether filiation is proved, and whether any heir validly renounced or was disqualified.

A valid will generally controls, but it cannot deprive a compulsory heir of the share reserved by law—the legitime—unless there is a valid disinheritance for a statutory cause. Without a valid will, intestate-succession rules determine the heirs and their proportions. No relative may simply take, sell, or transfer estate property before the estate is properly settled.

When inheritance rights arise

Successional rights are transmitted from the moment of death. This does not mean an heir immediately owns a particular house, lot, vehicle, or bank account. Until debts and taxes are addressed and the estate is partitioned, the heirs generally hold hereditary rights over the estate as a whole rather than exclusive ownership of specific assets.

An heir’s final share therefore cannot be computed reliably from a list of assets alone. The calculation ordinarily requires:

Determining which assets actually belonged to the decedent.
Separating the surviving spouse’s own share in community or conjugal property.
Identifying valid debts, taxes, and settlement expenses.
Determining whether there is a valid will.
Identifying all legally qualified heirs.
Computing legitimes, the disposable portion, and any required reductions or collation of donations.
Partitioning the remaining net estate.

Property exclusively owned by the surviving spouse is not part of the inheritance. Likewise, only the decedent’s share in community or conjugal property enters the estate after liquidation of the marital property regime.

Who are compulsory heirs?

Under Articles 886–903 of the Civil Code of the Philippines, compulsory heirs may include:

Legitimate children and descendants;
In their absence, legitimate parents and ascendants;
The surviving legal spouse;
Illegitimate children whose filiation is duly proved; and
Legally adopted children under the governing adoption law.

Not everyone in this list necessarily receives the same fraction, and some inherit only in default of nearer heirs. The precise legitime changes according to the combination of survivors.

A compulsory heir may demand completion of a deficient legitime. Testamentary gifts or lifetime donations that improperly reduce a legitime may be subject to reduction, but this generally requires a proper claim and a complete estate computation.

Legitimate, illegitimate, and adopted children

Legitimate children

Legitimate children inherit without distinction based on sex, age, order of birth, or the marriage from which they came. When several children inherit in their own right, they ordinarily divide the portion assigned to their class equally.

Illegitimate children

An illegitimate child has successional rights from the child’s parents, but filiation must be established through the evidence and within the periods allowed by the Family Code. Article 176 of the Family Code provides that an illegitimate child’s legitime is one-half of the legitime of a legitimate child.

That formula does not mean that an illegitimate child always receives exactly half of what a legitimate child ultimately receives. The surviving spouse, number and classes of children, available disposable portion, and other compulsory heirs can affect the calculation.

Grandchildren present a special issue. Ordinarily, children closer in degree exclude more remote descendants. A grandchild may inherit by right of representation when the law permits the grandchild to take the share that would have belonged to a predeceased, disinherited, or incapacitated parent. In Aquino v. Aquino, the Supreme Court construed Article 992 so that children, regardless of the circumstances of birth, may inherit from a direct ascendant such as a grandparent by representing their parent in the grandparent’s legitime. The ruling should not be extended casually to collateral relatives or to situations where the legal requirements for representation are absent. See the Supreme Court decision in Aquino v. Aquino.

Adopted children

Under Section 43 of the Domestic Administrative Adoption and Alternative Child Care Act, adopters and adoptees have reciprocal rights of succession without distinction from legitimate filiation. Adoption records, the date and effect of the adoption order, possible rescission, step-parent adoption, and rights involving biological relatives can create document-specific questions that require individual review.

A person merely raised as a child, listed informally as a beneficiary, or treated as part of the family is not automatically a legally adopted child. A simulated or inaccurate birth record should not be relied upon as a substitute for lawful adoption or legally established filiation.

Rights of the surviving spouse

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

For example, if an asset is community property, the surviving spouse may first receive the spouse’s share upon liquidation. Only the decedent’s remaining share enters the hereditary estate and is divided among the heirs, including the surviving spouse where applicable.

A boyfriend, girlfriend, fiancé, or live-in partner is not a surviving spouse and does not become an intestate or compulsory heir merely because the couple lived together for many years or had children. That partner may still have:

Ownership in property acquired through proven contributions or an applicable co-ownership rule;
Rights under a valid will, subject to the legitimes of compulsory heirs;
Contractual or insurance-beneficiary rights; or
A claim for reimbursement supported by evidence.

These are not the same as inheritance rights.

Legal separation can also affect succession. Under the Family Code, the spouse who gave cause for legal separation may be disqualified from inheriting from the innocent spouse by intestate succession. The decree, grounds, and status of the proceedings must be examined.

If there is a will

A will does not automatically eliminate the rights of compulsory heirs. It may dispose freely only of the portion not reserved as legitimes.

A will must also comply with statutory formalities. A notarized will is not necessarily valid merely because it was notarized, and a handwritten document is not necessarily invalid merely because it lacks notarization. A holographic will must satisfy the special Civil Code requirements applicable to wills entirely written, dated, and signed by the testator.

After death, a will must generally be submitted for probate. Rule 75 of the Rules of Court on Special Proceedings states that a will generally cannot pass real or personal property unless it is proved and allowed in the proper court. The heirs should not bypass probate through a private agreement that assumes the will is valid or invalid.

Omission and disinheritance are not the same

A parent cannot disinherit a compulsory heir merely by saying so orally, excluding the heir from family activities, or transferring possession of property to another child.

Valid disinheritance requires:

A will;
A cause expressly recognized by law;
Identification of that cause in the will; and
Proof of the cause if the disinherited heir contests it.

The Civil Code lists separate grounds for disinheriting children or descendants, parents or ascendants, and a spouse. If disinheritance is defective, the omitted heir may still claim the legitime.

Preterition is the total omission of a compulsory heir in the direct line from the inheritance without the heir being expressly disinherited and without receiving anything by another title. Its consequences differ from a mere shortfall in legitime and may affect the institution of heirs. This issue should be evaluated from the will and complete family record, not from a summary alone.

If there is no valid will

Intestate succession applies when there is no will, when the will is invalid, or when the will does not effectively dispose of the entire estate.

The Civil Code gives priority broadly to descendants, then—where applicable—to ascendants, illegitimate children, the surviving spouse, collateral relatives, and ultimately the State. These classes can concur in combinations expressly provided by law. A simple “nearest relative gets everything” rule is therefore unsafe.

Among the important principles are:

Nearer relatives generally exclude more remote relatives, subject to representation.
Children may inherit in their own right, while qualified descendants of a predeceased child may inherit by representation.
The surviving spouse may concur with children, parents, or illegitimate children.
Brothers, sisters, nephews, and nieces inherit only in situations allowed by the intestacy provisions.
Full-blood and half-blood collateral relatives can receive different proportions.
In default of qualified heirs, the estate may escheat to the State.

Because each additional surviving heir can alter every fraction, do not sign a deed based on an informal family-tree calculation.

Debts, taxes, and liability of heirs

Heirs inherit the balance after lawful estate obligations are paid. They should not distribute all assets first and deal with creditors later.

An heir is generally not personally liable beyond the value of property received from the estate. However, an heir who conceals assets, makes unauthorized withdrawals, sells estate property, or distributes assets despite known claims may create separate liability.

The estate-tax return is generally due within one year from the decedent’s death. Revenue Regulations No. 12-2018 allows a filing extension of no more than 30 days in meritorious cases and provides possible extensions or installment arrangements for payment under stated conditions. Filing and payment are different obligations; an extension to pay does not automatically extend the filing deadline. Consult the BIR estate-tax guidance and Revenue Regulations No. 12-2018.

For deaths covered by the former estate-tax-amnesty law, the extended availment period ended on June 14, 2025. Republic Act No. 11956 did not create a continuing amnesty after that date. Families with older unsettled estates should obtain a current BIR computation rather than assume that amnesty rates remain available.

Court settlement or extrajudicial settlement?

Extrajudicial settlement

Under Rule 74, an estate may generally be settled extrajudicially when:

The decedent left no will;
The decedent left no outstanding debts, subject to the rule’s presumption;
All heirs are of age, or minors are represented by duly authorized legal or judicial representatives; and
The heirs comply with the public-instrument, filing, publication, bond, tax, and registration requirements.

If there is only one heir, that heir may use an affidavit of self-adjudication when the requirements are satisfied.

Publication does not cure the exclusion of an heir. Rule 74 expressly provides that an extrajudicial settlement is not binding on a person who did not participate or had no notice. Likewise, the two-year provisions in Rule 74 do not automatically validate a fraudulent settlement or extinguish every remedy of an excluded heir. The applicable action and limitation period depend on participation, notice, fraud, possession, registration, and the relief sought.

Judicial settlement

Court proceedings are ordinarily necessary or prudent when:

There is a will requiring probate;
Heirs disagree on identity, shares, valuation, administration, or partition;
A compulsory heir was omitted;
There are unresolved debts or competing claims;
A minor’s interest lacks proper representation or authority;
The estate needs an administrator to recover, preserve, or sell property;
A will, deed, waiver, marriage, adoption, or filiation is disputed; or
Estate property has been concealed, transferred, or occupied adversely.

Venue and court jurisdiction depend on the decedent’s residence, the location of Philippine property in certain cases, and the governing procedural rules.

What an heir should do now

Secure the civil-registry records. Obtain the death certificate and relevant birth, marriage, adoption, annulment, legal-separation, and death records of possible heirs.
Locate the original will. Preserve envelopes, drafts, handwritten pages, and information about witnesses. Do not alter, staple, annotate, or discard the original.
Prepare an asset inventory. Include land, condominium units, vehicles, bank deposits, investments, business interests, insurance, receivables, digital assets, jewelry, and property held with other people.
Identify ownership, not merely possession. Gather titles, tax declarations, deeds, statements, marriage settlements, contribution records, loan documents, and proof of when and how each asset was acquired.
Preserve debt and expense records. Keep loan agreements, mortgages, medical and funeral receipts, tax notices, and proof of payments made for the estate.
Notify and identify all possible heirs. Do not proceed on the assumption that a child, previous spouse, adopted child, or descendant of a deceased child has no rights.
Protect the property. Maintain insurance, secure buildings, record rents and income, photograph movable assets, and keep a transparent accounting. Avoid private withdrawals or sales.
Register the estate and address taxes promptly. Confirm current forms, documentary requirements, payment channels, and the proper Revenue District Office directly with the BIR.
Choose the legally proper settlement route. Use extrajudicial settlement only if every Rule 74 condition is genuinely met. Otherwise, seek judicial settlement.
Execute partition and transfer documents only after verification. Confirm the family tree, net estate, tax clearance requirements, and each signatory’s authority before signing.

Evidence worth preserving

Keep originals or reliable certified copies of:

Birth, marriage, death, and adoption records;
The original will and codicils;
Land titles, tax declarations, deeds, and surveys;
Bank, investment, pension, insurance, and corporate records;
Loan, mortgage, and creditor documents;
Marriage settlements and records showing the applicable property regime;
Written acknowledgments of filiation and relevant communications;
Records of lifetime donations and advances to heirs;
Receipts for taxes, funeral costs, preservation expenses, and estate debts;
Photographs, inventories, appraisals, rental records, and keys;
Extrajudicial-settlement deeds, waivers, affidavits, publication proofs, and registration records; and
Messages or documents concerning concealed assets, threats, forgery, or unauthorized sales.

Make secure copies, but do not destroy or write on originals.

Common and costly mistakes

Dividing the gross property without first liquidating community or conjugal assets;
Treating a live-in partner as a legal spouse;
Assuming an eldest child, only son, or child who cared for the parent receives a larger statutory share;
Excluding an illegitimate child without examining proof of filiation;
Assuming grandchildren always inherit alongside living children;
Treating a waiver signed before the decedent’s death as a valid renunciation of a future legitime;
Believing publication makes an extrajudicial settlement binding on an omitted heir;
Selling a specific estate asset before partition without proper authority;
Using a deceased owner’s tax identification number or signature to transfer property;
Assuming possession, payment of real-property tax, or custody of a title proves exclusive ownership;
Ignoring lifetime donations that may be chargeable to a legitime or reducible;
Missing the estate-tax filing deadline while waiting for the family to agree; and
Signing a “waiver” that is actually a sale, donation, or assignment with different tax and legal consequences.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

Someone is about to sell, mortgage, withdraw, demolish, or conceal estate property;
A will may be lost, destroyed, forged, or withheld;
An heir was omitted from a deed or probate case;
A minor, incapacitated person, overseas heir, or unknown heir is involved;
Filiation, marriage, adoption, ownership, or the decedent’s mental capacity is disputed;
There are multiple marriages, foreign assets, foreign heirs, or a foreign will;
A creditor deadline, tax deadline, hearing, summons, or registration notice has arrived;
You are being pressured to sign a quitclaim, waiver, partition, or authority to sell;
Property has already been transferred to a buyer; or
Violence, coercion, falsification, or unauthorized access to accounts is suspected.

Immediate relief may depend on acting before property reaches an innocent third party or before evidence disappears.

Frequently asked questions

Can a parent leave everything to one child?

Only to the extent permitted by the disposable portion. A will or donation that impairs another compulsory heir’s legitime may be reduced upon a proper claim, unless that heir was validly disinherited.

Does the eldest child receive a bigger share?

No. Birth order and sex do not create a larger inheritance share under the general succession rules.

Can an illegitimate child inherit from the father?

Yes, if filiation is duly established and the child is otherwise qualified. The amount depends on the complete set of heirs and whether succession is testate or intestate.

Do grandchildren inherit when their parent is still alive?

Generally, the nearer descendant—the living child of the decedent—excludes that child’s own descendants. Grandchildren may inherit independently if named within the disposable portion or in circumstances where representation or another legal rule applies.

Can an heir refuse an inheritance?

Yes, but acceptance or repudiation must comply with the Civil Code. A repudiation cannot be partial or conditional, and formal requirements may apply. An heir should understand the property, debts, taxes, and effects on descendants and co-heirs before acting.

Is an oral family agreement enough?

Usually not for transferring or partitioning registered land or completing an extrajudicial settlement. Required public instruments, tax compliance, publication, court authority where necessary, and registration still matter.

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

An heir may not ordinarily treat an unpartitioned estate asset as exclusively theirs. Use, expenses, fruits, rent, and accounting should be agreed upon or resolved through the estate proceeding.

Does paying real-property tax make someone the sole owner?

No. Tax declarations and receipts may be evidence, but they are not by themselves conclusive proof of exclusive ownership or a valid transfer from all heirs.

Can estate property be sold before settlement?

Sometimes, but authority and consent depend on whether the estate is under administration, whether all co-heirs can validly act, the rights of minors and creditors, and the purpose of the sale. A buyer from only one heir may acquire no more than that heir’s eventual undivided interest, subject to the final partition.

How long does an heir have to challenge an extrajudicial settlement?

There is no single safe answer for every challenge. Rule 74 contains two-year provisions for particular claims, but omitted heirs without participation or notice, fraud, void instruments, reconveyance, co-ownership, and registered-property claims may be governed differently. Obtain advice as soon as the deed or transfer is discovered.
