Quick answer

Philippine law protects certain heirs even when there is a will. Legitimate children and descendants, qualifying parents or ascendants, the surviving legal spouse, illegitimate children whose filiation is proved, and adopted children may have rights that cannot simply be erased by giving the estate to someone else.

If there is no valid will, the Civil Code determines who inherits and in what proportions. If there is a will, compulsory heirs must generally receive their legitime—the minimum share reserved by law—unless they were validly disinherited for a statutory cause stated in the will and proved when challenged.

An heir inherits only from the decedent’s net estate: the property belonging to the decedent after marital-property liquidation, valid debts, taxes, and administration expenses. Heirs do not automatically become sole owners of particular houses, land, vehicles, or accounts. Until partition, multiple heirs generally own the estate in common, subject to estate debts.

The controlling rules are primarily in the Civil Code, Articles 774–1105, the Family Code, the Rules of Court on estate settlement, and special laws on adoption and taxation.

What passes to the heirs

Succession transmits the decedent’s property, transmissible rights, and obligations upon death. The heirs’ liability for inherited obligations is limited to the value of the inheritance. Personal rights and obligations that legally end at death do not pass to them.

The starting point is not the total value of everything the decedent used or possessed. The estate must first identify:

Property exclusively owned by the decedent;
The decedent’s net share in absolute-community or conjugal property;
Receivables and other transmissible rights;
Valid debts, mortgages, taxes, and administration expenses;
Lifetime donations that must be considered in computing legitimes or partition; and
Property or benefits that pass under a separate contract or special law rather than through the estate.

For example, after liquidation of community or conjugal property, the surviving spouse’s own share belongs to that spouse as an owner, not as an heir. Only the deceased spouse’s net share enters the hereditary estate. The surviving spouse may then inherit an additional portion from that estate. The applicable marital-property regime, marriage settlements, source of funds, and dates of acquisition can change the calculation. The Family Code provisions on property relations and liquidation should therefore be applied before inheritance shares are computed.

Likewise, insurance, employment death benefits, retirement benefits, and similar payments may be governed by a beneficiary designation, contract, or special law. They should not be assumed to be estate property without examining the governing documents.

When inheritance rights begin

Rights to succession are transmitted at the moment of death, although acceptance or repudiation has legal effects retroactive to that moment. The Supreme Court has confirmed that compulsory or intestate heirs may, in appropriate circumstances, enforce succession-based ownership rights without first obtaining a separate declaration of heirship, provided no estate or heirship proceeding is already pending. The exact procedural route still depends on the relief sought. See Treyes v. Antonio, G.R. No. 232579, September 8, 2020.

Where there are several heirs, they generally become co-owners of the estate before partition. This does not give one heir exclusive ownership of a particular bedroom, farm, vehicle, bank account, or portion of land. A co-heir may deal with an undivided hereditary interest, but a purported sale of a definite part of an unpartitioned property normally cannot prejudice the shares of the other co-heirs. See Article 1078 and the Supreme Court’s explanation in Heirs of Ureta v. Heirs of Ureta.

Who are compulsory heirs

Under Article 887 of the Civil Code, the principal compulsory heirs are:

Legitimate children and descendants, with respect to their legitimate parents and ascendants;
In the absence of legitimate children or descendants, legitimate parents and ascendants;
The surviving legal spouse; and
Illegitimate children, provided filiation is duly proved.

The surviving spouse and illegitimate children are not automatically excluded by the presence of legitimate children or legitimate parents. Their shares instead have to be fitted together under the Civil Code’s rules on legitimes.

Legitimate children and descendants

Legitimate children are primary compulsory heirs. Their collective legitime is generally one-half of the net hereditary estate, divided equally among those inheriting in their own right. The other half is the free portion, but it remains subject to the legitimes of the surviving spouse and illegitimate children.

A grandchild ordinarily does not inherit in place of a living parent who is nearer in degree. Representation may apply when the parent who would have inherited predeceased the decedent or was legally incapable or validly disinherited. Representation does not arise merely because the parent voluntarily repudiates the inheritance.

Illegitimate children

An illegitimate child is a compulsory heir of the child’s parents once filiation is legally established. Under Article 176 of the Family Code, as amended by Republic Act No. 9255, each illegitimate child’s legitime is one-half of the legitime of a legitimate child, subject to the Civil Code rules protecting the surviving spouse and limiting the amount available from the free portion.

Using the father’s surname is not the test of inheritance. What matters is legally sufficient proof of filiation. Depending on the facts, this may include the civil-registry birth record, a final judgment, an admission of filiation in a public document or private handwritten instrument, or other evidence allowed by Articles 172 and 175 of the Family Code.

Filiation disputes are especially time-sensitive. The applicable deadline may depend on the child’s birth date, the evidence relied upon, when the Family Code became effective, and whether rights had already vested. Legal advice should be obtained immediately when a parent has died without formally recognizing a child.

An illegitimate grandchild is not automatically barred from representing a predeceased parent in the estate of a direct ascendant. The Supreme Court held that children, regardless of the circumstances of birth, may inherit from a direct ascendant such as a grandparent by right of representation, provided filiation and the other requirements for representation are proved. The ruling did not resolve every possible issue involving collateral relatives. See Aquino v. Aquino, G.R. Nos. 208912 and 209018, December 7, 2021.

Adopted children

Under Republic Act No. 11642, an adoptee is treated as the legitimate child of the adopter and has reciprocal succession rights with the adopter without discrimination from legitimate filiation. The legal filiation extends as provided by the statute.

Rights involving the adoptee’s biological family require closer examination of the adoption order, the governing adoption law, whether a biological parent is the adopter’s spouse, and whether succession is testate or intestate. Do not rely only on an amended birth certificate or on general assumptions that every biological-family right was either retained or severed.

Surviving spouse

Only the surviving spouse in a legally recognized marriage ordinarily inherits as a spouse. Separation in fact does not by itself dissolve the marriage. A spouse who gave cause for a judicial decree of legal separation may be disqualified from intestate succession, while Article 892 contains a corresponding rule for compulsory succession.

A partner in a void marriage or an unmarried live-in partner is not automatically a compulsory or intestate heir as a spouse. That partner may nevertheless own property independently or have a co-ownership claim under Articles 147 or 148 of the Family Code. Ownership must be determined before inheritance is calculated.

Parents, siblings, and other relatives

Legitimate parents or ascendants become compulsory heirs when there are no legitimate children or descendants. They may still concur with a surviving spouse or illegitimate children under specific rules.

Brothers, sisters, nephews, nieces, and more distant collateral relatives are generally not compulsory heirs. They can inherit in intestacy when the relatives given priority by law are absent. Intestate succession through collateral relatives does not extend beyond the fifth degree. If no qualified heir exists, the estate may escheat to the State.

If there is a will

A will does not automatically eliminate the rights of compulsory heirs. The estate must first calculate and satisfy their legitimes. Only the legally disposable portion may be freely given to another person.

The legitime depends on the combination of survivors. Common starting rules include:

Legitimate children or descendants collectively receive one-half of the hereditary estate as their legitime.
Legitimate parents or ascendants, when there are no legitimate descendants, generally receive one-half.
A surviving spouse’s legitime varies depending on whether the spouse concurs with one or several legitimate children, legitimate ascendants, illegitimate children, or no other compulsory heir.
An illegitimate child’s individual legitime is one-half of that of a legitimate child, but the collective shares may be limited by the disposable portion and the surviving spouse’s priority.
A surviving spouse who is the only compulsory heir generally has a legitime of one-half, subject to the special rule for certain marriages solemnized in articulo mortis.
If only illegitimate children survive as compulsory heirs, their collective legitime is generally one-half.

The complete combinations appear in Articles 888–903 of the Civil Code. A percentage should not be applied until the family tree, filiation, marital status, property regime, debts, and lifetime donations have been verified.

A will must be probated

No will passes real or personal property unless it is proved and allowed by the proper court. A private agreement to “follow” or disregard an unprobated will is not a substitute for probate.

A person holding the will must deliver it to the proper court or the named executor within 20 days after learning of the testator’s death. A named executor must generally present the will and accept or refuse the trust within the corresponding 20-day period. These requirements appear in Rules 75 and 76 of the Rules of Court.

Preserve the original document. Do not staple additional pages to it, erase marks, write notes on it, or circulate the only original unnecessarily.

Omission is not always valid disinheritance

A parent cannot disinherit a child merely by saying, “I leave this child nothing,” unless the will identifies a legal ground for disinheritance and the statutory requirements are satisfied.

Valid disinheritance requires:

A will;
A cause expressly recognized by law;
Specification of that cause in the will; and
Proof of the cause by the other heirs if the disinherited heir denies it.

The statutory causes include particular forms of serious misconduct listed in Articles 919–921. Ordinary family conflict, disappointment, estrangement, or unequal affection is not by itself a substitute for a statutory cause.

If the cause is not specified, is not legally sufficient, or cannot be proved, the disinheritance is ineffective to the extent that it prejudices the heir’s legitime.

Preterition is different. It is the total omission, without valid express disinheritance, of a compulsory heir in the direct line. Under Article 854, preterition may annul the institution of heirs, while devises and legacies remain effective only insofar as they do not impair protected shares. A compulsory heir who received something but less than the legitime may instead seek completion of the legitime or reduction of excessive dispositions. See In re Estate of Wenceslao, G.R. No. 254695, December 6, 2023.

If there is no valid will

Intestate succession applies when there is no will, the will is invalid, the will does not dispose of the entire estate, or a testamentary disposition fails without an effective substitute or right of accretion.

The following are useful general guides. Each row assumes that no other class of heir that would alter the result exists.

Survivors	General intestate result
Legitimate children only	They inherit in equal shares; descendants of a predeceased child may represent that child per stirpes.
Surviving spouse and legitimate children only	The spouse generally receives the same share as each legitimate child.
Surviving spouse and illegitimate children only	The spouse receives one-half; the illegitimate children collectively receive one-half.
Surviving spouse and legitimate parents or ascendants only	The spouse receives one-half; the ascendants receive one-half.
Surviving spouse and siblings or children of siblings only	The spouse receives one-half; the siblings or their qualifying descendants receive one-half.
Illegitimate children only, with no legitimate descendants or ascendants and no spouse	They inherit the estate, subject to representation where proper.
Parents or nearest legitimate ascendants only	They inherit according to the rules on degree and division between paternal and maternal lines.
Surviving spouse alone, with no descendants, ascendants, illegitimate children, siblings, nephews, or nieces	The spouse inherits the entire intestate estate.

Mixed families require special care. The presence of one legitimate child, several illegitimate children, and a surviving spouse may prevent a simple “2:1” calculation because no compulsory heir’s legitime may be impaired. In a 2024 decision involving one legitimate child, a surviving legal spouse, and two illegitimate children, the Supreme Court applied shares of one-half, one-fourth, and one-eighth for each illegitimate child. The decision explains why the number and combination of heirs matter. See Macalinao v. Macalinao, G.R. No. 250613, April 3, 2024.

That example should not be copied into a different family configuration without a fresh computation.

Acceptance and renunciation

An heir may accept or repudiate an inheritance only after the decedent’s death and after becoming certain of the right to inherit.

Acceptance may be express or implied by conduct. Selling, donating, or assigning hereditary rights can amount to acceptance. Acts merely intended to preserve the estate do not necessarily constitute acceptance if the person has not assumed the status of heir.

Repudiation must be made in a public or authentic instrument or by a petition filed in the court handling the estate. A parent or guardian needs judicial authorization to repudiate an inheritance for a minor or incapacitated heir. A purported waiver of a future inheritance or future legitime made while the owner is still alive is void.

A “waiver in favor of” a selected co-heir can have consequences different from a pure repudiation, including possible tax consequences. The wording and intended recipient should be reviewed before signing.

Extrajudicial or judicial settlement

Extrajudicial settlement

An extrajudicial settlement under Rule 74 is generally available when:

The decedent left no will;
There are no outstanding debts;
All heirs participate;
All heirs are of age, or minors are represented by duly authorized judicial or legal representatives; and
The required public instrument, filing, publication, and bond requirements are satisfied.

If there is only one heir, that heir may use an affidavit of self-adjudication. With several heirs, the settlement is embodied in a notarized public instrument. It must be filed with the Register of Deeds when required, and the settlement must be published in a newspaper of general circulation in the manner prescribed by Rule 74.

Publication does not cure the omission of an heir. Rule 74 expressly states that an extrajudicial settlement is not binding on a person who did not participate or had no notice.

For two years after distribution, the bond and estate property remain subject to claims contemplated by Rule 74. A minor, mentally incapacitated person, prisoner, or person outside the Philippines at the end of that period may have one year after the disability is removed to present the Rule 74 claim. These periods should not be treated as automatic bars to every possible action by an omitted heir, particularly where there was no notice, fraud is alleged, or the property remains co-owned. Obtain advice promptly rather than waiting for a limitation dispute.

Judicial settlement

Judicial settlement is usually necessary or safer when:

There is a will requiring probate;
Heirs dispute filiation, shares, ownership, or the validity of transactions;
A qualified heir is missing or omitted;
There are unpaid or contested debts;
The estate needs an administrator to collect, preserve, lease, or sell property;
The heirs cannot agree on partition; or
The proposed transaction affecting a minor or incapacitated heir requires court authority.

For probate cases filed under the present jurisdictional law, first-level courts have jurisdiction when the estate value does not exceed ₱2 million, while Regional Trial Courts handle probate matters when the gross estate exceeds ₱2 million. Venue and jurisdiction must both be checked. See Republic Act No. 11576.

In judicial administration, the court sets a creditor-claim period of not less than six months and not more than 12 months from first publication of the notice. A late claim may be allowed for cause, before an order of distribution, within the limited additional period provided by Rule 86.

Estate tax and transfer requirements

Inheritance shares and estate tax are different questions. An heir may have a valid hereditary right even while taxes and title transfers remain unsettled.

For deaths on or after January 1, 2018:

Estate tax is generally 6% of the net taxable estate;
The standard deduction for a citizen or resident’s estate is ₱5 million;
The family-home deduction is limited to ₱10 million, subject to the statutory conditions;
A return showing a gross estate above ₱5 million requires the prescribed CPA-certified statement; and
The estate tax return is generally due within one year from death.

These rules come from Republic Act No. 10963, or the TRAIN Law. Different laws, rates, deductions, and documentary rules may apply when the death occurred before 2018.

Under Republic Act No. 11976, estate tax returns and payments may be made through the authorized electronic or manual channels specified by law and BIR regulations. The tax is generally paid when the return is filed and before the executor or administrator delivers distributive shares.

Extensions or installments are not automatic. The Tax Code permits limited relief in qualifying cases, including an installment period when estate cash is insufficient and approved extensions for undue hardship. Apply before assuming that additional time has been granted.

Registered or registrable property—such as land, vehicles, or shares—normally requires BIR clearance or an electronic Certificate Authorizing Registration before ownership records can be transferred. Check the current requirements on the BIR Estate Tax page and with the office handling the estate.

Practical steps for heirs

Secure civil-registry documents. Obtain the PSA death certificate and certified birth, marriage, and adoption records needed to establish relationships.
Locate the original will and codicils. Record who held them and when that person learned of the death. Observe the 20-day delivery rule.
Prepare a complete family tree. Include all marriages, children from every relationship, adopted children, deceased children and their descendants, parents, and relevant siblings. Do not omit a person because of estrangement or birth status.
Inventory assets and liabilities. List real property, vehicles, bank and investment accounts, shares, businesses, receivables, insurance, benefits, digital assets, loans, mortgages, unpaid taxes, and claims against the decedent.
Classify marital and exclusive property. Review marriage settlements, titles, acquisition dates, deeds, and proof of payment before calculating the estate.
Preserve and account for the property. Secure premises, maintain insurance, pay necessary preservation expenses, record rents and withdrawals, and avoid distributing cash informally.
Check lifetime transfers. Gather deeds of donation, waivers, advances, and records of property placed in another person’s name. Some donations must be collated or reduced to protect legitimes.
Choose the lawful settlement route. Do not use self-adjudication when more than one heir exists or an extrajudicial settlement when there is a will, unresolved debt, missing heir, or genuine dispute.
File the estate tax return on time. Do not wait for every family disagreement to end before addressing the one-year tax deadline.
Partition and transfer only after verification. The settlement instrument, tax clearance, titles, and agency-specific transfer requirements should be consistent with the final allocation.

Evidence worth preserving

Keep originals where possible and make secure copies of:

The will, codicils, envelopes, and proof of custody;
PSA and local civil-registry certificates;
Adoption orders and amended birth records;
Written acknowledgments of filiation and handwritten admissions;
Land titles, tax declarations, deeds, surveys, and property-tax receipts;
Bank statements, passbooks, investment records, stock certificates, and loan documents;
Marriage settlements and evidence showing when and how property was acquired;
Deeds of donation, waivers, advances, and records of prior transfers;
Insurance policies and beneficiary forms;
Receipts for funeral, medical, tax, maintenance, and preservation expenses;
Rental contracts and records of estate income;
The deed of settlement, affidavit of self-adjudication, publication affidavit, newspaper issues, bond, BIR filings, payment confirmations, and eCAR; and
Messages, notices, and transaction records showing concealment, exclusion of an heir, unauthorized withdrawals, forgery, or pressure concerning a will.

Do not secretly alter, backdate, destroy, or “correct” documents. Preserve disputed originals for forensic examination.

Common mistakes

Treating the surviving spouse’s marital-property share as the spouse’s entire inheritance;
Dividing the gross property without first deducting debts and settling the marital-property regime;
Assuming a child has no rights because the parents were unmarried or the child uses the mother’s surname;
Excluding adopted children;
Letting one heir sign an affidavit of self-adjudication despite other heirs;
Believing newspaper publication makes an omitted heir’s rights disappear;
Selling a definite portion of unpartitioned land without all co-owners’ consent;
Assuming possession or payment of real-property tax makes one heir the sole owner;
Treating siblings as compulsory heirs when children, qualifying parents, or a spouse survive;
Ignoring the original will and proceeding directly to extrajudicial settlement;
Calling a simple family disagreement “disinheritance” without a valid will and statutory cause;
Signing a waiver without understanding whether it is repudiation, assignment, sale, or donation;
Distributing assets before paying estate debts and taxes; and
Waiting for title-transfer negotiations before addressing the estate tax deadline.

When legal help is urgent

Seek a Philippine succession lawyer promptly if:

The one-year estate tax deadline is approaching or has passed;
Someone is hiding, destroying, or refusing to deliver a will;
Money is being withdrawn or property sold without an accounting;
A child’s filiation is disputed or was not formally acknowledged before the parent died;
An heir was omitted from an extrajudicial settlement or title;
A signature, will, deed, birth record, or affidavit may be forged;
The estate includes minors, incapacitated persons, foreign heirs, overseas property, corporations, or several marriages;
The surviving marriage or a later marriage may be void;
Creditors are foreclosing or a court creditor-claim period is running;
A beneficiary is pressuring an elderly or vulnerable person to sign documents;
The family cannot agree on administration, valuation, sale, or partition; or
Property has already been transferred to a buyer.

Urgent relief may include preserving documents, annotating a claim, seeking an administrator, demanding an accounting, stopping an unauthorized disposition, contesting probate, or filing the proper recovery or partition action. The available remedy and deadline depend on the documents and procedural history.

Frequently asked questions

Can a parent leave everything to only one child?

Not ordinarily if other compulsory heirs survive. The favored child may receive that child’s legitime plus some or all of the disposable portion, but dispositions that impair another compulsory heir’s legitime may be reduced.

Can an illegitimate child inherit from the father?

Yes, if paternal filiation is legally established. The child’s surname alone is not decisive. In general, the child’s individual legitime is one-half of a legitimate child’s legitime, subject to the rules governing the particular combination of heirs.

Does the eldest child receive a larger share?

No general rule gives the eldest child a larger inheritance merely because of age, sex, or birth order.

Does a grandchild inherit if the grandchild’s parent is still alive?

Ordinarily, the nearer relative—the living parent—excludes the grandchild. A grandchild may inherit directly under a will from the disposable portion or through representation when its legal requirements are present.

Can a surviving spouse sell the entire family property?

Not merely because the other spouse died. The surviving spouse may own a marital-property share and an hereditary share, but the decedent’s remaining share belongs to the estate and other heirs. A sale cannot normally bind their portions without lawful authority or consent.

Can one heir live in the inherited house without paying the others?

A co-heir may use co-owned property only in a manner consistent with its purpose and without excluding or prejudicing the other co-owners. Exclusive possession, collection of rents, expenses, and demands for accounting can affect the parties’ rights. The facts should be documented.

Can heirs settle the estate without going to court?

Yes, but only when Rule 74’s requirements for extrajudicial settlement are met. A will must be probated, and disputes, debts, missing heirs, or transactions requiring court authority may require judicial settlement.

Can an heir refuse an inheritance with debts?

An heir may repudiate after death through the legally required instrument or court petition. The decision should be made before acts that could constitute acceptance. In any event, inherited liability is generally limited to the value of the inheritance.

Is a verbal family agreement enough?

A verbal understanding is unsafe and often legally insufficient, especially for real property. Estate settlement, partition, renunciation, and transfer documents must satisfy their respective formal and registration requirements.

Do heirs need to pay estate tax before dividing the property?

Estate obligations, including applicable estate tax, should be resolved before final delivery and transfer. The BIR clearance required for registered assets will ordinarily prevent completion of title transfer without tax compliance.
