Quick answer

Under Philippine law, a person’s inheritance rights generally arise at the moment the property owner dies. The heirs do not automatically receive every asset free and clear: the estate must first be identified, the deceased’s property regime and ownership shares determined, and lawful debts, taxes, expenses, and other obligations settled.

Who inherits—and how much—depends mainly on:

whether there is a valid will;
the deceased’s surviving spouse, children, parents, and other relatives;
whether filiation, marriage, or adoption is legally established;
which assets actually belonged to the deceased;
lifetime donations that may have to be accounted for; and
any valid disinheritance, unworthiness, renunciation, or other legal disqualification.

A will cannot ordinarily take away the legitime, or minimum protected share, of a compulsory heir. A compulsory heir may be deprived of that share only through a valid disinheritance made in a will for a cause expressly recognized by law, or through another applicable legal ground established with evidence.

The estate is not the same as everything the deceased possessed

Before computing any inheritance, determine what belongs to the estate.

If the deceased was married, the applicable property regime—such as absolute community of property, conjugal partnership of gains, or complete separation of property—must be settled first. The surviving spouse’s own share in community or conjugal property is not an inheritance. Only the deceased spouse’s share enters the hereditary estate.

The estate may include land, condominium units, vehicles, bank deposits, investments, business interests, receivables, intellectual property, and other transferable rights. It may also include claims against people who improperly obtained or retained the deceased’s property.

From the gross estate, the proper liabilities and allowable charges must be considered. Only the resulting hereditary estate is divided among heirs and beneficiaries. Titles, tax declarations, account names, or possession are important evidence, but they do not always conclusively establish exclusive ownership.

Under Article 777 of the Civil Code, successional rights are transmitted from the moment of death. This does not mean that an heir may immediately take a particular house, withdraw an entire account, or sell a specific estate asset as exclusively theirs. Until settlement and partition, heirs commonly hold hereditary rights in the undivided estate, subject to administration, debts, taxes, and the rights of other heirs.

Inheritance with a will

A person may distribute property through a valid will, but testamentary freedom is limited by the legitimes of compulsory heirs.

No will passes property unless it is proved and allowed in probate. A handwritten document, notarized paper, family agreement, video, text message, or verbal instruction does not replace the legal requirements for a will. Even an apparently valid will must be submitted to the proper court for allowance.

The court initially examines matters such as due execution, testamentary capacity, voluntariness, and compliance with the required formalities. Questions about whether particular provisions impair legitimes may also have to be resolved in the estate proceedings.

Who are compulsory heirs?

Depending on who survives and which relatives concur, compulsory heirs may include:

legitimate children and descendants;
in their absence, legitimate parents and ascendants;
the surviving legal spouse;
legally recognized illegitimate children and their descendants in the cases allowed by law; and
adopted children, whose succession rights are generally treated without distinction from legitimate filiation under the current adoption law.

The word “compulsory” does not mean that all these groups always inherit together. For example, legitimate parents are ordinarily excluded by legitimate children or descendants. The surviving relatives and the rules on concurrence must be examined before calculating anyone’s share.

What is a legitime?

A legitime is the portion of the estate that the law reserves for a compulsory heir. The balance, if any, is the free portion that the testator may generally give to another person.

Common starting rules include:

The collective legitime of legitimate children or descendants is ordinarily one-half of the hereditary estate, divided among them according to law.
If there are no legitimate descendants, the collective legitime of legitimate parents or ascendants is ordinarily one-half, subject to the special rule when they concur with a surviving spouse.
The surviving spouse’s legitime varies according to the relatives with whom the spouse concurs.
Under Article 176 of the Family Code, the legitime of each illegitimate child is one-half of the legitime of a legitimate child, subject to the rules governing the available portion and concurrence with other compulsory heirs.
An adopted child has reciprocal succession rights with the adopter without distinction from legitimate filiation, subject to the precise terms and effects of the adoption.

These are starting points, not a substitute for a complete computation. The number and status of heirs, property regime, lifetime donations, debts, and provisions of the will can materially change the result.

What if a will gives an heir too little?

A compulsory heir who receives less than the proper legitime may seek completion of that share. Testamentary gifts that impair legitimes may be reduced to the extent necessary.

If a testator completely omits a compulsory heir in the direct line without expressly disinheriting that heir and without giving the heir anything, the omission may constitute preterition. Its effect can be more serious than merely adjusting percentages: Article 854 may annul the institution of heirs, while preserving valid devises and legacies to the extent allowed by law. Whether an omission is true preterition depends on the will and the relevant family facts.

Disinheritance requires more than family conflict

A parent cannot validly disinherit a child merely by saying, “I no longer consider you my heir,” transferring property to another relative, or writing an unsupported accusation.

Under Articles 915 to 923 of the Civil Code:

disinheritance must be made in a will;
the will must specify a legal cause recognized by law; and
if the disinherited heir denies the accusation, the persons benefiting from the disinheritance bear the burden of proving the cause.

The authorized causes differ for children and descendants, parents and ascendants, and a spouse. They include particular forms of serious misconduct listed by law; ordinary estrangement, disagreement, disapproval of a marriage, or failure to visit is not automatically enough.

If the cause is not legally sufficient, is not stated, or is not proved when disputed, the disinheritance may be ineffective and the heir may seek restoration of the impaired legitime. Reconciliation may also affect a prior cause for disinheritance.

Separate from disinheritance, the Civil Code recognizes incapacity or unworthiness to succeed for specified acts. That issue likewise requires application of the statutory grounds to established facts.

Inheritance when there is no valid will

If the deceased left no will, the will is invalid, or the will does not dispose of the entire estate, the applicable property passes by intestate succession.

The following are simplified common patterns:

Surviving heirs	General intestate rule
Legitimate children only	They generally divide the estate equally, subject to representation where applicable.
Surviving spouse and legitimate children	The spouse generally receives the same share as each legitimate child.
Legitimate and illegitimate children	A legally established illegitimate child generally receives one-half of the share of a legitimate child.
Spouse, legitimate children, and illegitimate children	The spouse generally receives a share equal to one legitimate child; each illegitimate child generally receives one-half of a legitimate child’s share.
Illegitimate children only	They generally divide the estate among themselves in the proportions provided by law.
Legitimate parents, with no legitimate descendants	The parents or proper ascendants inherit under the ascending-line rules.
Spouse and legitimate parents	The spouse generally receives one-half and the legitimate parents or ascendants receive the other half.
Spouse and illegitimate children, without legitimate descendants or ascendants	The spouse generally receives one-half and the illegitimate children or their descendants receive the other half.
Spouse and brothers, sisters, nephews, or nieces, with no descendants, ascendants, or illegitimate children	The spouse generally receives one-half, and the qualifying collateral relatives receive the other half under the applicable rules.
Spouse alone, with no other heirs entitled to concur	The spouse generally inherits the entire estate.

The exact result may differ where there are grandchildren, half-blood siblings, nephews or nieces, remote relatives, adopted children, multiple family lines, legal separation, or questions about the validity of a marriage.

Representation by descendants

Representation allows certain descendants to step into the place of a person who predeceased the decedent, is incapacitated, or was disinherited in circumstances covered by law. In the direct descending line, representation can preserve a family branch’s share. In the collateral line, it is limited to the children of brothers or sisters.

Representation is not available in every situation. A person who voluntarily repudiates an inheritance generally cannot be represented for that same succession, although their children may inherit in their own right if the law independently calls them.

Rights of children born outside marriage

An illegitimate child is a compulsory heir of their legally established parent. The child’s legitime is generally one-half of that of a legitimate child, and intestate shares follow the corresponding Civil Code and Family Code rules.

The right depends on legally provable filiation. Useful evidence may include:

a PSA birth certificate;
an admission of filiation in a public document;
a private handwritten instrument signed by the parent;
proof of open and continuous possession of the status of a child; and
other evidence allowed under the Family Code and Rules on Evidence.

A birth record must be examined carefully, including who supplied or signed the information. Merely naming a person as the father does not resolve every filiation dispute.

Time limits for establishing filiation depend on the kind of evidence relied upon and other facts. If the alleged parent has died, the estate is already being settled, or the child was omitted from a settlement, legal advice is urgent.

Article 992 of the Civil Code also creates an intestate-succession barrier between an illegitimate child and the legitimate children and relatives of the child’s parent. Its application—especially where a grandchild claims through representation—can be legally and factually difficult. The Supreme Court’s en banc decision in Aquino v. Aquino applied the statutory barrier in the case before it. Do not assume that a right to inherit from one’s parent automatically creates a right to inherit from every relative of that parent.

Rights of adopted children

Under Republic Act No. 11642, an adoptee is considered the legitimate child of the adopter for all intents and purposes and has reciprocal testate and intestate succession rights with the adopter without distinction from legitimate filiation. The law also extends the created legitimate filiation to specified members of the adopter’s family.

Except in a stepparent-adoption situation covered by the law, legal ties between the biological parents and the adoptee are generally severed and vested in the adopters. The adoption order, its date, whether it remains effective, and whether the case involves stepparent adoption must be reviewed before determining rights in the biological or adoptive families.

Rights of the surviving spouse

Only a legally recognized spouse generally inherits as a surviving spouse. A long-term partner, fiancé, or cohabiting partner does not acquire the spouse’s intestate share merely because the couple lived together or had children.

That does not mean an unmarried partner can never own property. They may have an ownership claim based on their actual contribution and the property rules applicable to unions without marriage. An ownership claim must be separated from an inheritance claim.

The following may also affect a claimed spousal share:

a void, annulled, or legally dissolved marriage;
a prior subsisting marriage;
legal separation and which spouse caused it;
a pending dispute over marital status;
the marriage settlement and property regime; and
whether the property was exclusive, community, or conjugal property.

Grandchildren, parents, siblings, and more remote relatives

A grandchild does not automatically receive a separate share whenever the grandchild’s parent is alive and able to inherit. Children in the nearer degree generally exclude more remote descendants, subject to representation.

Legitimate parents or ascendants are generally compulsory heirs only when there are no legitimate children or descendants. In intestate succession, descendants usually exclude ascendants.

Brothers, sisters, nephews, and nieces are not compulsory heirs. They may inherit by intestacy when the law’s preferred classes are absent, and they may sometimes concur with a surviving spouse. Full-blood and half-blood relationships can produce different shares.

Other collateral relatives may inherit only within the degree allowed by the Civil Code. If no person is entitled to inherit under the will or the intestate rules, the estate may pass to the State under the statutory rules.

Can an heir be excluded through a donation or sale?

Not always.

A genuine sale made during the owner’s lifetime generally removes the sold property from the estate, but its validity may be challenged if, for example, the transaction was simulated, the seller lacked capacity or consent, the supposed buyer never paid, or another legal defect exists.

Lifetime donations may have to be considered in computing the estate and legitimes. Donations to children or other compulsory heirs can be subject to collation, unless an applicable exemption exists. Excessive donations may be reduced if they impair the legitimes of compulsory heirs.

An heir challenging a transaction needs evidence, not merely suspicion that the arrangement was unfair. Preserve deeds, bank records, proof of payment, tax records, medical records relevant to capacity, messages, signatures, and evidence showing who possessed or benefited from the property.

Can one heir sell inherited property?

Before partition, an heir generally owns hereditary rights in the undivided estate—not exclusive ownership of every particular asset. A co-heir who sells more than their lawful rights cannot ordinarily defeat the rights of the others.

If an heir sells hereditary rights to a stranger before partition, Article 1088 allows the other co-heirs to be subrogated to the buyer’s rights by reimbursing the purchase price. They must act within one month from written notice of the sale. Because the period is short and the sufficiency of notice may be disputed, obtain legal advice immediately.

A buyer should investigate the death, identities of all heirs, estate settlement, authority of the seller, title annotations, taxes, and possible unrepresented minors before purchasing estate property.

Accepting or renouncing an inheritance

An heir is not generally forced to accept an inheritance. Acceptance may be express or implied through acts that necessarily show an intention to accept. Renunciation must comply with the Civil Code’s formal requirements; an informal family conversation may not be enough.

An heir should not sign a waiver without first determining:

the assets and liabilities of the estate;
the heir’s actual share;
whether the document is a pure renunciation or effectively transfers the share to specified persons;
possible donor’s, estate, or other tax consequences;
whether consideration is being paid; and
whether the waiver includes unknown claims.

A waiver cannot retroactively validate fraud, erase another heir’s rights, or dispose of the inheritance of a minor without the required authority.

How an estate may be settled

Probate or judicial settlement

Court proceedings are generally necessary when there is a will to probate, unpaid or disputed debts, disagreement among heirs, uncertainty about heirship or ownership, a need for administration, or another issue that cannot safely be handled extrajudicially.

Venue generally depends on the deceased’s residence at death, subject to the detailed provisions of Rule 73 and special rules applicable to nonresidents.

Extrajudicial settlement

Under Rule 74, an extrajudicial settlement may generally be used when:

the deceased left no will;
the estate has no outstanding debts, subject to the rule’s provisions;
all heirs participate;
the heirs are of age, or minors are properly represented by judicial or legal representatives duly authorized for the purpose; and
the requirements for a public instrument, filing, bond where applicable, and publication are met.

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

Publication is not a cure for deliberately excluding an heir. Rule 74 expressly states that an extrajudicial settlement is not binding on a person who did not participate or had no notice. The rule also provides a two-year protection period concerning claims against distributees and the estate, but that period should not be treated as a universal deadline for every omitted-heir, fraud, reconveyance, ownership, or title claim. The applicable remedy and prescriptive period depend on the cause of action, notice, possession, registration, fraud, and other facts.

Partition

After debts and charges are addressed, heirs may divide the estate by agreement or seek judicial partition if they cannot agree. Before signing a partition, verify that all heirs, properties, encumbrances, and prior transfers have been disclosed.

Estate tax and transfer requirements

Estate tax is separate from the heirs’ ownership shares. Tax compliance does not determine who the lawful heirs are, and payment by one person does not by itself make that person the sole owner.

For deaths covered by the TRAIN amendments, the estate tax is generally 6% of the net estate, and the estate tax return is generally due within one year from the date of death. Different rules may apply to earlier deaths, estates covered by special laws, or available tax-amnesty provisions.

An estate tax return may be required regardless of value when the estate includes registered or registrable property for which BIR clearance is needed to transfer ownership. A return showing a gross estate exceeding ₱5 million must generally be supported by a CPA-certified statement containing the information required by law.

Where estate cash is insufficient, the Tax Code provides mechanisms that may include installment payment and an authorized extension in qualifying circumstances. These are not automatic; confirm the current requirements with the BIR office handling the estate before the statutory deadline.

Late filing or payment may result in surcharge, interest, compromise penalties, and delays in obtaining the electronic Certificate Authorizing Registration or other clearance needed for transfers.

Practical steps for an heir

Secure civil-registry records. Obtain the PSA death certificate and relevant birth, marriage, adoption, annulment, or legal-separation records.
Look for the original will. Do not conceal, alter, destroy, or rely solely on a photocopy without legal advice.
Identify every possible heir. Include children from prior relationships, legally adopted children, descendants of predeceased children, the surviving spouse, and qualifying parents or collateral relatives.
Inventory assets and debts. Check titles, tax declarations, bank accounts, investments, vehicles, businesses, insurance documents, loans, judgments, and pending cases.
Determine ownership before inheritance. Separate the surviving spouse’s or another co-owner’s property from the deceased’s share.
Preserve the estate. Secure property, photograph its condition, record income and expenses, and prevent unauthorized withdrawals, sales, or transfers.
Request an accounting. A person managing estate funds should keep receipts, statements, rent records, inventories, and proof of every disbursement.
Check taxes and title annotations early. Do not wait until a buyer appears before addressing estate tax, real-property taxes, mortgages, adverse claims, or missing documents.
Choose the correct settlement procedure. Do not use self-adjudication when there are other heirs, or an extrajudicial settlement when the legal conditions are absent.
Have every waiver, settlement, or sale independently reviewed. Once signed, notarized, registered, or acted upon, reversal can become difficult and expensive.

Evidence worth preserving

Keep originals or reliable copies of:

birth, marriage, death, and adoption records;
wills, codicils, deeds, titles, tax declarations, and surveys;
bank statements and transaction histories around the time of death;
stock certificates and business records;
loan documents, receipts, and proof of estate expenses;
records of donations or property advances;
medical records relevant to capacity, if legitimately obtainable;
handwriting and signature samples;
messages discussing ownership, filiation, sales, donations, or estate plans;
proof of payment or nonpayment for questioned sales;
publication notices and complete settlement documents;
written notices of any sale of hereditary rights; and
evidence showing when an omitted heir learned of a settlement or transfer.

Preserve electronic evidence in its original form where possible. Screenshots alone may omit metadata and context.

Common mistakes

Treating the eldest child as automatically entitled to a larger share.
Assuming sons inherit more than daughters.
Assuming the person named on a tax declaration necessarily owned the entire property.
Dividing community or conjugal property as though all of it belonged to the deceased.
Excluding an illegitimate child whose filiation is legally established.
Assuming a cohabiting partner has the same rights as a legal spouse.
Using an affidavit of self-adjudication despite the existence of other heirs.
Believing publication automatically binds an omitted heir.
Selling a specific estate asset as though one heir owned it alone.
Withdrawing or spending estate money without authority and records.
Signing a “waiver” without understanding its tax and ownership effects.
Paying estate tax but failing to complete settlement and registration.
Assuming a private will controls property without probate.
Waiting until records disappear or property is transferred to a purported buyer in good faith.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

an heir was omitted from an affidavit or extrajudicial settlement;
estate property is being sold, mortgaged, withdrawn, demolished, or transferred;
the one-month period under Article 1088 may apply;
a will is being concealed, destroyed, or challenged;
filiation or marital status is disputed;
a minor or incapacitated heir is involved;
signatures, deeds, or withdrawals appear fraudulent;
the estate has significant debts or tax exposure;
a foreign will, foreign heir, or property abroad is involved;
there are competing spouses or families;
an heir is being pressured to sign a waiver;
the estate-tax deadline is near or has passed; or
a court, BIR, Registry of Deeds, bank, or other institution has issued a deadline or formal notice.

Qualified indigent parties may ask the Public Attorney’s Office whether they meet its requirements for legal assistance.

Frequently asked questions

Does the eldest child receive the biggest share?

No. Birth order does not ordinarily increase a child’s inheritance. Children of the same legal class generally receive equal shares, subject to representation and the different statutory share applicable to an illegitimate child.

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 and some or all of the free portion, but dispositions impairing other compulsory heirs’ legitimes may be reduced.

Can an illegitimate child inherit from the father?

Yes, if filiation is legally established and no applicable disqualification exists. The child’s share is determined under the Family Code and Civil Code rules on legitime or intestate succession.

Does an illegitimate child inherit from grandparents?

Not automatically. Article 992 and the rules on representation can bar particular intestate claims through the legitimate family of a parent. The exact family line, the parent’s status, filiation, and the presence of a will must be examined.

Does a grandchild inherit while the child’s parent is alive?

Usually not in a separate capacity when the nearer-degree parent is alive and qualified to inherit. Exceptions may arise under a will or other specific legal rules.

Can siblings inherit if the deceased had children?

They generally do not inherit by intestacy when descendants entitled to inherit survive. A valid will may give siblings part of the free portion without impairing compulsory heirs’ legitimes.

Is a verbal promise to give property after death enforceable?

A verbal promise is not a substitute for a legally valid will. A separate completed contract, sale, or donation may present a different issue, but its legal requirements and evidence must be examined.

Can heirs settle the estate without going to court?

Sometimes. An extrajudicial settlement may be available only when Rule 74’s requirements are met. A will, unresolved debt, excluded heir, disputed ownership, or disagreement may require judicial proceedings.

Can one heir occupy the family home without paying the others?

An heir may have co-ownership rights, but exclusive use against the objections of other co-heirs can create claims for accounting, reasonable compensation, partition, or other relief depending on the circumstances. No heir should assume that possession gives exclusive ownership.

Can inheritance include debts?

Heirs receive the estate subject to lawful obligations. They are not ordinarily liable beyond the value of property received from the estate under the applicable succession rules, but administration, secured debts, guarantees, and acts personally undertaken by an heir require separate analysis.

Can an heir refuse the inheritance?

Yes, but repudiation must comply with legal formalities and should be made only after understanding the assets, liabilities, taxes, and consequences. A selective or person-specific “waiver” may operate differently from a pure renunciation.
