Quick answer

Under Philippine law, inheritance rights arise at the moment a person dies. The heirs acquire rights to the estate immediately, but subject to valid debts, taxes, administration, the surviving spouse’s property share, and the eventual settlement and partition of the estate. Until partition, co-heirs generally own undivided shares—not particular rooms, lots, vehicles, or bank accounts.

A will does not give a person unlimited power to distribute property. Certain compulsory heirs are entitled to a protected minimum share called the legitime. Without a valid will, the Civil Code’s rules on intestate succession determine who inherits and in what proportions.

The exact result depends on documents and facts, especially:

whether there is a valid will;
the decedent’s citizenship and date of death;
the validity of the marriage and applicable property regime;
the number and status of children, including adopted and nonmarital children;
whether a child or other heir died before the decedent;
whether filiation has been legally established;
lifetime donations and transfers;
estate debts, taxes, and ownership disputes; and
whether any heir has validly repudiated the inheritance, been disinherited, or is legally unworthy to inherit.

The controlling provisions are principally found in the Civil Code, Family Code, Rules of Court, adoption laws, and Supreme Court decisions.

What is included in an inheritance?

An inheritance includes property, transmissible rights, and obligations that are not extinguished by death. It can include land, condominium units, houses, vehicles, business interests, shares of stock, money, receivables, intellectual-property rights, and the decedent’s share in community or conjugal property.

Debts do not simply disappear, but heirs generally answer for estate obligations only to the extent of the value of what they inherit. A separate personal undertaking—such as an heir’s own guaranty—may produce a different result.

Not every payment made after death necessarily forms part of the distributable estate. Life-insurance proceeds, pension or retirement benefits, survivorship arrangements, and statutory death benefits may follow a beneficiary designation, contract, or special law. Each instrument must be checked.

Inheritance by will and inheritance by law

If there is a will

Testamentary succession follows a will executed in the form required by law. Philippine law recognizes, among others, notarial and holographic wills, each with different formal requirements.

A will cannot be used privately as if it were already conclusive. Under Rule 75, no will passes real or personal property unless it is proved and allowed by the proper court. A person who has custody of a will must deliver it to the proper court or named executor within 20 days after learning of the testator’s death. The executor has a corresponding 20-day duty after learning of the death or appointment.

Even a valid will must respect compulsory heirs’ legitimes. The testator may freely dispose only of the portion not reserved by law and may bequeath specific property only within applicable ownership and legitime limits.

If there is no valid will

Intestate succession applies when:

the person dies without a will;
the will is void or has lost its validity;
the will does not dispose of the entire estate;
an instituted heir cannot or will not inherit and no substitution, representation, or accretion applies; or
another circumstance under Article 960 of the Civil Code leaves property undisposed of.

Intestacy may apply to the entire estate or only to the portion not effectively disposed of by the will.

Who are compulsory heirs?

Compulsory heirs are persons for whom the law reserves a legitime. Depending on who survives the decedent, they may include:

legitimate children and descendants;
in their absence, legitimate parents and ascendants;
the surviving legal spouse;
illegitimate or nonmarital children whose filiation is duly established; and
adopted children, who enjoy succession rights without distinction from legitimate filiation under the Domestic Administrative Adoption and Alternative Child Care Act.

These categories interact. The presence of children may exclude parents, but a surviving spouse and illegitimate children may still concur with legitimate children.

Siblings, nephews, nieces, other collateral relatives, and an unmarried partner are not compulsory heirs merely because of closeness, dependency, or years spent caring for the decedent. They may inherit under intestacy when the nearer statutory classes are absent, or under a valid will within the disposable portion.

What is a legitime?

A legitime is the minimum portion of the hereditary estate reserved for a compulsory heir. It is not necessarily a percentage of each title or physical asset. It is ordinarily satisfied by value after the estate and all relevant lifetime donations have been properly accounted for.

Some core rules are:

Compulsory heir	General legitime rule
Legitimate children or descendants	Collectively, one-half of the hereditary estate, divided under the rules on succession and representation
Legitimate parents or ascendants	In the absence of legitimate descendants, collectively one-half of the hereditary estate
Surviving spouse	Varies according to the other surviving compulsory heirs; it is not always one-half
Each illegitimate child	One-half of the legitime of a legitimate child, subject to the rules protecting the surviving spouse and the available portion
Adopted child	Succession rights without distinction from legitimate filiation

The calculation cannot safely begin with the gross value of all property seen in the decedent’s name. The family-property regime must first be liquidated, valid debts and charges considered, and donations subject to collation added back when computing legitimes.

A compulsory heir who receives less than the legitime may demand completion of that share. Excessive testamentary dispositions or donations may be reduced upon a proper claim.

Common intestate combinations

The following are simplified Civil Code rules for common situations. They assume there is no valid will and do not account for special facts such as representation, renunciation, unworthiness, adoption rescission, reserva troncal, or cross-border succession.

Survivors	General intestate division
Legitimate children only	They inherit in equal shares
Legitimate and illegitimate children, no spouse	Each illegitimate child generally receives one-half of the share of each legitimate child
Surviving spouse and legitimate children	The spouse receives the same share as each legitimate child
Surviving spouse, legitimate children, and illegitimate children	The spouse receives the same share as a legitimate child; each illegitimate child generally receives half of a legitimate child’s share
Surviving spouse and illegitimate children only	One-half to the spouse; one-half collectively to the illegitimate children or their qualifying descendants
Legitimate parents or ascendants and surviving spouse	One-half to the parents or ascendants; one-half to the spouse
Legitimate ascendants, surviving spouse, and illegitimate children	One-half to the ascendants; one-fourth to the spouse; one-fourth collectively to the illegitimate children
Illegitimate children only, with no legitimate descendants or ascendants	They inherit the entire estate
Surviving spouse and siblings or qualifying nephews and nieces	One-half to the spouse; one-half to the collateral heirs
No descendants, ascendants, illegitimate children, or spouse	Brothers, sisters, and qualifying nephews and nieces inherit first; more remote collateral relatives may inherit only up to the fifth degree
No qualified legal heir	The estate passes to the State under the Civil Code and Rules of Court

These proportions apply to the net hereditary estate, not automatically to all community or conjugal property.

The surviving spouse’s own property share comes first

The surviving spouse may have two legally distinct interests:

the spouse’s own share after liquidation of the absolute community or conjugal partnership; and
the spouse’s inheritance from the deceased spouse’s estate.

The first is ownership, not inheritance. Only the deceased spouse’s net share, together with the deceased’s exclusive property, enters the hereditary estate.

The Family Code generally requires community or conjugal property to be liquidated in the estate proceeding. If there is no judicial proceeding, the surviving spouse must liquidate it judicially or extrajudicially within six months from death. A disposition or encumbrance involving unliquidated community or conjugal property after that period may be void under Articles 103 and 130.

The actual division may differ from a simple 50–50 assumption because exclusive property, reimbursements, debts, marriage settlements, forfeitures, and the date and validity of the marriage may affect liquidation.

Rights of legitimate, illegitimate, and adopted children

Legitimate and legitimated children

Children do not receive more merely because they are older, male, married, financially dependent, or living with the parent. Children in the same legal position generally inherit equally. A legitimated child enjoys the same rights as a legitimate child.

Illegitimate or nonmarital children

An illegitimate child may inherit from either parent once filiation is duly established. Under Article 176 of the Family Code, each illegitimate child’s legitime is one-half of a legitimate child’s legitime.

Having a different surname does not by itself defeat inheritance rights. Conversely, using the alleged father’s surname, being publicly treated as a child, or presenting an ordinary birth record does not always establish every element of filiation. Relevant proof can include a properly executed civil-registry record, an admission in a public document or private handwritten instrument, a final judgment, and other evidence permitted by the Family Code. The permissible evidence and period for bringing a filiation action depend on the legal basis and facts, so delay can be dangerous.

The Supreme Court’s 2021 decision in Aquino v. Aquino clarified the treatment of nonmarital descendants under Article 992. The “iron curtain” prohibition applies when a person seeks to inherit in their own right; it does not prevent a qualified descendant from inheriting by representation in the direct descending line. Thus, a child may represent a predeceased nonmarital parent in the estate of a grandparent when the requirements for representation are met. The ruling did not erase every restriction involving collateral relatives. See Aquino v. Aquino, G.R. No. 208912, 7 December 2021.

Adopted children

A legally adopted child is treated as the legitimate child of the adopter for succession purposes. Under Republic Act No. 11642, adopters and adoptees have reciprocal rights in testate and intestate succession without distinction from legitimate filiation.

The effect of adoption on succession involving biological relatives, prior adoption laws, step-parent adoption, rescission, and the date of the adoption order requires examination of the applicable statute and documents.

When grandchildren inherit by representation

Representation allows a qualified descendant to take the place and degree of a person who would have inherited but predeceased the decedent or could not inherit in circumstances recognized by law. Distribution is then made per stirpes, meaning the representatives divide only the share that their parent or represented person would have received.

Representation ordinarily operates in the direct descending line. In the collateral line, it is limited to children of brothers or sisters in the situations allowed by law.

A child generally cannot represent a parent who merely repudiated the inheritance. Representation, substitution, and transmission of an heir’s already vested right are different doctrines and must not be treated as interchangeable.

A will cannot casually disinherit a compulsory heir

Disinheritance is valid only if:

it is made in a valid will;
the will identifies a legal cause expressly recognized by the Civil Code;
the cause applies to the particular compulsory heir; and
if the heir denies the accusation, the persons relying on the disinheritance prove it.

Family conflict, estrangement, disapproval of a spouse, failure to visit, or a general statement that a child is “ungrateful” is not automatically a statutory cause. The Civil Code lists specific grounds, including certain attacks on life, serious misconduct, fraud or coercion concerning a will, unjustified refusal of support, and maltreatment.

An ineffective disinheritance does not necessarily invalidate the entire will. Testamentary provisions remain effective to the extent that they do not impair the disinherited heir’s legitime.

Omission from a will or settlement

Preterition is not every omission from a will. It generally involves the total omission of a compulsory heir in the direct line from the inheritance, without the heir having received anything by testamentary disposition or otherwise chargeable to the inheritance. It may annul the institution of heirs, while devises and legacies remain valid insofar as they are not excessive.

Omission from an extrajudicial settlement is a separate issue. Rule 74 states that an extrajudicial settlement is not binding on a person who did not participate in it or had no notice. Publication does not automatically cure the deliberate or accidental exclusion of an heir.

There is no single limitation period that safely covers every omitted-heir case. Participation, notice, fraud, registration, adverse possession, repudiation of co-ownership, and the remedy requested can lead to different periods. The Rule 74 two-year provision should not be assumed to bar every claim by an excluded heir.

Rights of heirs before partition

From the moment of death, the heirs generally become co-owners of the hereditary estate, subject to estate obligations and settlement. Before partition:

no heir ordinarily owns a specific physical portion solely because that heir lives there or holds the title;
each heir may protect the common property and demand an accounting;
an heir may generally transfer only the heir’s undivided hereditary interest, subject to the result of partition;
one heir cannot validly sell or mortgage the entire property as sole owner without authority from the other owners or the court;
rent, harvests, dividends, and other fruits must be accounted for; and
any co-owner may ordinarily seek partition.

Long possession by one co-heir does not automatically erase the others’ rights. Prescription against co-heirs generally requires clear, adverse, and exclusive possession, an unequivocal repudiation of the co-ownership, actual or legally sufficient notice to the other co-heirs, and the applicable prescriptive period.

An unmarried partner’s position

A live-in or common-law partner is not automatically a surviving spouse, compulsory heir, or intestate heir. The partner may nevertheless own a share of property acquired during cohabitation under Articles 147 or 148 of the Family Code, depending on the parties’ capacity to marry and their contributions.

That ownership claim must be separated from inheritance. The partner may also be named in a will, subject to the legitimes of compulsory heirs and statutory prohibitions on certain testamentary gifts. The couple’s children may have their own inheritance rights once filiation is established.

Accepting or refusing an inheritance

Acceptance may be express or implied by acts that only an heir would have the right to perform. Selling, donating, or assigning an hereditary right may amount to acceptance.

Repudiation must be made in a public or authentic instrument or through a petition in the estate proceeding. It is generally irrevocable once validly made, except in limited circumstances such as vitiated consent or the later discovery of an unknown will.

A supposed “waiver” in favor of selected heirs can also be treated as an acceptance followed by a donation or transfer, potentially producing donor’s tax and other consequences. Do not sign a waiver, quitclaim, deed of sale, or extrajudicial settlement without first computing its civil and tax effects.

Parents or guardians need judicial authority to repudiate an inheritance belonging to a minor or incapacitated person.

How an estate is settled

Extrajudicial settlement

Under Rule 74, heirs may ordinarily settle the estate without a full administration proceeding when:

the decedent left no will;
there are no outstanding debts;
all heirs participate;
the heirs are of age and legally capable, or minors and incapacitated persons are properly represented by representatives authorized for the purpose; and
the rule’s public-instrument, publication, bond, and registration requirements are satisfied.

If there is only one heir, an affidavit of self-adjudication may be used when the conditions are met. The fact of the settlement or adjudication must be published once a week for three consecutive weeks in a newspaper of general circulation in the province. See Rule 74 of the Rules of Court.

Publication is not a substitute for identifying and obtaining the participation of every heir. A deed signed only by selected heirs binds, at most, the interests they can legally convey.

Judicial settlement

Court proceedings are usually necessary or prudent when:

there is a will requiring probate;
heirs dispute their identities, shares, filiation, ownership, or the validity of documents;
an heir was omitted or cannot be located;
substantial debts or competing creditor claims remain;
an administrator or executor must recover or preserve property;
there is suspected fraud, concealment, dissipation, or forgery;
a guardian’s authority or court approval is necessary; or
extrajudicial agreement is impossible.

In a judicial administration, the court fixes the creditor-claim period. Under Rule 86, the stated period must be no less than six months and no more than 12 months from the date of the first publication of the notice. A creditor or claimant should not wait until the estate is distributed.

Estate tax and transfer requirements

For deaths on or after 1 January 2018, the TRAIN law generally imposes estate tax at 6% of the net taxable estate. For a citizen or resident, the principal deductions include a ₱5 million standard deduction and, subject to statutory conditions, a family-home deduction of up to ₱10 million. Different rules apply to nonresident aliens.

An estate-tax return is required in all taxable transfers and, regardless of gross value, when the estate includes registered or registrable property for which a BIR electronic Certificate Authorizing Registration is required. If the gross estate exceeds ₱5 million, the return must be supported by the required CPA-certified statement.

The general filing deadline is one year from death. In meritorious cases, the Commissioner may grant a filing extension of no more than 30 days. Tax is generally paid when the return is filed, electronically or manually through a channel authorized by law and BIR rules. When payment would cause undue hardship, an approved payment extension may be available for up to five years for judicial settlement or two years for extrajudicial settlement. Installment or partial-disposition arrangements require BIR approval.

The tax law in force on the date of death governs. Do not apply the current rate and deductions automatically to an older estate. The extended estate-tax amnesty for qualified deaths on or before 31 December 2021 ended on 14 June 2025; it should not be treated as presently open. See the TRAIN Act, Ease of Paying Taxes Act, Republic Act No. 11956, and the BIR estate-tax page.

An eCAR, proof of settlement, and the receiving agency’s documentary requirements are normally needed before land, shares, vehicles, and similar registered assets can be transferred to the heirs.

Practical steps for heirs

Secure the death and civil-status records. Obtain the PSA death certificate and relevant birth, marriage, adoption, annulment, or legal-separation records.
Locate and protect the original will. Do not staple, mark, alter, or detach pages. Record who found it, where, and when, and comply with the 20-day delivery rule.
Prepare a complete family tree. Include all marriages, children, adopted children, nonmarital children, predeceased relatives, and descendants who might inherit by representation.
Inventory property and debts as of the date of death. Identify whether each asset was exclusive, community, conjugal, co-owned, held in trust, or subject to a beneficiary designation.
Preserve and secure the estate. Prevent unauthorized withdrawals, transfers, demolition, harvesting, sale, or removal of valuables. Keep a written record of necessary preservation expenses.
Obtain valuations and account statements. Date-of-death values affect estate tax, legitimes, equalization, and partition.
Choose the proper settlement route. Do not execute an extrajudicial settlement if the Rule 74 conditions are absent.
Compute shares only after liquidation and accounting. Separate the surviving spouse’s property, validate debts, identify donations subject to collation, and then calculate hereditary shares.
Register the estate and address taxes promptly. Use the current BIR form, checklist, filing channel, and RDO procedure applicable to the estate.
Transfer each asset through the proper registry. A notarized settlement alone does not update a land title, corporate stock book, vehicle record, or bank account.

Evidence worth preserving

Keep originals where possible and maintain secure digital copies of:

wills, codicils, envelopes, and probate filings;
PSA birth, marriage, and death certificates;
adoption and filiation orders or acknowledgments;
marriage settlements and judgments affecting marital status;
land titles, deeds, tax declarations, surveys, and real-property-tax records;
bank, investment, loan, insurance, pension, and corporate records;
vehicle registrations and business documents;
receipts and proof of ownership or contribution;
lifetime donation, sale, trust, and assignment documents;
appraisals and date-of-death account balances;
debt instruments, mortgages, tax liabilities, and creditor notices;
rent, harvest, dividend, and expense records;
communications showing acknowledgment of heirs, demands for accounting, or repudiation of co-ownership; and
proof of publication, service, participation, and signatures in any settlement.

Do not rely solely on photocopies supplied by the person controlling the property. Obtain certified records directly from the issuing registry when authenticity or completeness is disputed.

Common mistakes

Assuming the eldest child controls the estate.
Excluding a child because of a different surname, family conflict, residence abroad, or birth outside marriage.
Treating the surviving spouse’s property share as part of the inheritance.
Dividing gross assets without first paying or reserving for valid debts and taxes.
Using an unprobated will to transfer property.
Signing an extrajudicial settlement without every heir’s informed participation.
Believing publication cures an omitted heir.
Selling the entire property when the seller owns only an undivided hereditary share.
Treating possession of the title or occupancy of the house as sole ownership.
Ignoring lifetime donations that may affect legitimes.
Using present estate-tax rules for a death that occurred under an older tax law.
Signing a waiver without considering whether it constitutes acceptance, donation, or sale.
Waiting for years despite a contested filiation, forged deed, adverse title transfer, creditor notice, or disappearing estate assets.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

a will may be hidden, altered, destroyed, or withheld;
the 20-day will-delivery period is running;
the one-year estate-tax deadline is approaching or has passed;
the six-month period for liquidating a deceased spouse’s community or conjugal property is approaching;
the court has published a Rule 86 creditor-claim deadline;
an heir’s filiation is disputed or the alleged parent is still alive;
someone is selling, mortgaging, withdrawing, or transferring estate property without authority;
an extrajudicial settlement or affidavit of self-adjudication contains a false statement;
an heir has been omitted, impersonated, or made to sign without understanding;
rents, crops, business income, or valuables are being concealed;
there are competing marriages, foreign heirs, foreign assets, or questions about the decedent’s citizenship;
minors or incapacitated heirs are involved; or
a co-heir has openly repudiated the co-ownership and claimed exclusive ownership.

Emergency court remedies may be available to preserve property, require an accounting, annotate a claim, appoint an administrator, or prevent an unauthorized disposition. The appropriate remedy depends on the property and evidence.

Frequently asked questions

Can a parent leave everything to only one child?

Not if other compulsory heirs survive and the disposition impairs their legitimes. The favored child may keep only the amount permitted by the will and the disposable portion, subject to reduction of excessive dispositions and accounting for relevant lifetime donations.

Does an illegitimate child inherit from the father?

Yes, if paternal filiation is duly established. Each illegitimate child’s legitime is generally one-half of a legitimate child’s legitime. In intestacy, the final proportion depends on all surviving heirs.

Can grandchildren inherit while their parent is alive?

Ordinarily, the nearer relative excludes the more remote one. Grandchildren commonly inherit by representation when their parent predeceased the decedent or could not inherit in a situation recognized by law. A living parent’s simple refusal of an inheritance does not ordinarily allow the parent’s children to represent that parent.

Does an adopted child have the same inheritance rights?

A legally adopted child has succession rights without distinction from legitimate filiation in relation to the adopter. Biological-family succession and older or rescinded adoptions may require examination of the applicable adoption law.

Does a live-in partner inherit automatically?

No. A partner who is not a legal spouse has no automatic legitime or intestate share as a spouse. The partner may, however, own a cohabitation-property share and may have rights under a valid will, contract, or beneficiary designation.

Can one heir sell inherited land without the others?

An heir may generally transfer only the heir’s undivided interest. The buyer acquires no greater right and receives only what may ultimately be allotted to the seller. Sale of the entire property ordinarily requires all owners’ participation or proper judicial authority.

Can heirs refuse an inheritance with heavy debts?

Yes, but repudiation must follow the required form and is generally irrevocable. Because estate liability is ordinarily limited to the inheritance’s value, obtain a full inventory and legal and tax advice before refusing.

Can a sibling be excluded from an extrajudicial settlement?

A settlement that omits an heir who did not participate or have notice is not binding on that heir. Publication alone does not authorize the participating heirs to appropriate the omitted heir’s share.

Is there a fixed deadline for an omitted heir to sue?

There is no universal deadline. The applicable period depends on the cause of action, participation or notice, fraud, registration, possession, and whether co-ownership was clearly repudiated. Seek advice immediately rather than relying on the Rule 74 two-year period.

Does paying estate tax prove that someone is the sole heir?

No. Estate-tax filing and payment do not conclusively determine civil ownership or heirship. Heirship comes from law, a valid probated will, and the proper settlement or judicial determination.
