Quick answer

Under Philippine law, an heir’s rights generally arise at the moment of the decedent’s death. But an heir does not automatically own every asset personally or have an immediate right to sell a particular house, lot, vehicle, or bank account. The estate must first be identified, the surviving spouse’s own property share separated, valid debts and taxes addressed, the heirs determined, and the remaining estate partitioned.

A valid will controls only within legal limits. Certain compulsory heirs are entitled to protected shares called legitimes and ordinarily cannot be excluded without a valid statutory ground for disinheritance. If there is no valid will—or the will does not dispose of the entire estate—the Civil Code’s rules on intestate succession determine who inherits and in what proportions.

The result depends on the complete family tree, the validity of marriages and adoption orders, proof of filiation, the applicable property regime, the date of death, the existence and validity of a will, prior donations, debts, and possible disqualification or renunciation. No heir should sign an extrajudicial settlement, waiver, sale, or deed of self-adjudication until those matters have been checked.

What an heir actually inherits

Succession transfers the decedent’s transmissible property, rights, and obligations, but only obligations that are not extinguished by death and only up to the value of the inherited property. The governing principle is in Articles 774, 776, and 777 of the Civil Code.

The estate may include:

Land, condominium units, houses, and other real property owned by the decedent
The decedent’s share in community or conjugal property
Bank deposits, investments, shares of stock, vehicles, businesses, receivables, and valuable personal property
Contractual and property rights that survive death
Property recoverable from persons who improperly transferred, concealed, or retained it
In some cases, property donated during life that must be considered in computing legitimes

Not everything associated with the decedent necessarily belongs to the estate. Examples requiring separate examination include:

The surviving spouse’s own share in community or conjugal property
Property owned exclusively by another person
Insurance, retirement, death, or survivorship benefits payable directly under a governing law, plan, or valid beneficiary designation
Property merely held in trust or borrowed by the decedent
Rights or obligations extinguished by death

A title, tax declaration, registration record, passbook, or possession of property is important evidence, but it may not conclusively settle beneficial ownership.

Separate the surviving spouse’s property before dividing the inheritance

A surviving spouse may receive property in two different capacities:

As an owner, through liquidation of the spouses’ absolute community or conjugal partnership; and
As an heir, from the deceased spouse’s net hereditary estate.

These are not the same. For example, if an asset is community or conjugal property, the surviving spouse’s share under the marital property regime is separated first. Only the decedent’s net share enters the hereditary estate. The applicable proportion may change if there are reimbursable advances, exclusive property, valid marriage settlements, or obligations chargeable to only one spouse.

A partner who was not legally married to the decedent is generally not a compulsory or intestate heir merely because they lived together for many years or had children. That partner may nevertheless have an ownership claim over property acquired through their joint contribution under Articles 147 or 148 of the Family Code. The partner may also inherit under a valid will, subject to the legitimes of compulsory heirs and other legal restrictions.

Who are compulsory heirs?

Article 887 of the Civil Code identifies the principal compulsory heirs:

Legitimate children and descendants
In their absence, legitimate parents and ascendants
The surviving spouse
Nonmarital children whose filiation is legally established

These groups do not always inherit together. For example, legitimate parents are generally excluded as compulsory heirs when legitimate children or descendants inherit. Descendants in a more remote degree do not ordinarily inherit while their parent in the nearer degree is alive and qualified, except where representation or another specific rule applies.

An adopted child has the legal status and succession rights provided by the adoption law. Under the Domestic Administrative Adoption and Alternative Child Care Act, Republic Act No. 11642, an adoption creates the legal parent-child relationship addressed by the statute. The adoption order, its date, the identity of the adopter or adopters, and any later rescission must be examined. If an adoption is validly rescinded, succession rights revert prospectively as provided by the Act, while vested rights acquired before rescission are respected.

What is a legitime?

A legitime is the portion of the estate that the testator cannot freely give away because the law reserves it for compulsory heirs.

Common Civil Code rules include:

The collective legitime of legitimate children and descendants is generally one-half of the hereditary estate, divided among them as the law provides.
The surviving spouse’s legitime depends on which other compulsory heirs survive.
Each nonmarital child’s legitime is generally one-half of the legitime of a legitimate child, subject to rules protecting the legitimes of all compulsory heirs.
When legitimate parents or ascendants inherit as compulsory heirs, their legitime depends on whether a surviving spouse or other heirs concur.

These fractions must be applied to the net hereditary estate, not automatically to the gross value of every asset. The calculation may require:

Determining which assets belong to the decedent;
Liquidating the marital property regime;
Deducting enforceable obligations and proper estate charges;
Adding donations that the law requires to be considered in the legitime computation; and
Reducing donations or testamentary gifts that impair a compulsory heir’s legitime.

Because several classes of heirs can concur, a share should not be calculated from a single relationship in isolation.

If there is a valid will

A will may designate heirs, give particular assets as devises or legacies, impose lawful conditions, and provide for partition. But it cannot disregard protected legitimes.

A will must also comply with legal formalities. A holographic will must be entirely written, dated, and signed by the testator. A notarial will is subject to the signing, witnessing, attestation, acknowledgment, and page requirements in the Civil Code. Apparent defects should be assessed from the original document, not from a summary or photocopy alone.

A will cannot simply be implemented privately. Under Rule 75 of the Rules of Court on Special Proceedings, no will passes property unless it is proved and allowed in the proper court. A person who has custody of a will after the testator’s death should preserve it and promptly obtain advice on producing it for probate.

Omitted or disinherited heirs

An heir is not validly disinherited merely because the will says, “I leave nothing to my child.”

Under Articles 915 to 923 of the Civil Code:

Disinheritance must be made in a will.
The will must specify a legal cause expressly recognized by law.
If the disinherited heir denies the cause, the persons who benefit from the disinheritance carry the burden of proving it.
Reconciliation, an invalid cause, or failure to prove the cause may defeat the disinheritance.

Preterition is different. It generally means the total omission of a compulsory heir in the direct line from the inheritance, without that heir having received anything by will or otherwise. Under Article 854, preterition can annul the institution of heirs, while valid devises and legacies remain effective to the extent they are not excessive. The consequences are technical and depend on whether the omission was complete and whether the omitted person was already legally an heir when succession opened.

If there is no valid will

When a person dies intestate, the Civil Code calls heirs by legal order. In simplified form, descendants are generally preferred, followed by qualifying ascendants, with the surviving spouse and nonmarital children inheriting in the combinations established by law. Collateral relatives may inherit when the preferred classes are absent. The State ultimately inherits if no qualified heir exists.

Common intestate patterns include:

Survivors	General intestate rule
Legitimate children only	They divide the estate equally, subject to representation
Legitimate children and surviving spouse	The spouse generally receives a share equal to that of each legitimate child
Legitimate children, nonmarital children, and spouse	The spouse generally takes the share of one legitimate child; each nonmarital child generally takes one-half of a legitimate child’s share
Nonmarital children and surviving spouse, with no legitimate descendants or qualifying ascendants	One-half generally goes to the spouse and one-half collectively to the nonmarital children
Legitimate parents and surviving spouse, with no descendants	One-half generally goes to the parents or ascendants and one-half to the spouse
Surviving spouse alone, with no descendants, ascendants, nonmarital children, or qualifying collateral heirs	The spouse generally takes the entire estate
Surviving spouse with brothers, sisters, nephews, or nieces, and no preferred heirs	The spouse generally takes one-half and the qualifying collateral heirs collectively take one-half
Brothers and sisters only	Full-blood siblings generally receive twice the share of half-blood siblings

This table is only a starting point. Representation, adoption, half-blood relationships, disqualification, the validity of the marriage, and the existence of descendants from an heir who died earlier can change the distribution.

Grandchildren and the right of representation

Representation allows a person to step into the place of a nearer relative in situations recognized by law. It applies principally in the direct descending line and, in limited cases, in the collateral line for children of brothers or sisters.

A grandchild does not ordinarily inherit directly while the grandchild’s parent—the decedent’s child—is alive and qualified. Representation may apply when that parent predeceased the decedent, is incapacitated or unworthy to inherit, or was disinherited, subject to the Civil Code’s specific rules. As a general rule, representation does not arise merely because the nearer heir renounces the inheritance.

In Aquino v. Aquino, G.R. Nos. 208912 and 209018, December 7, 2021, the Supreme Court held that a nonmarital child may represent a deceased parent in inheriting from a direct ascendant, such as a grandparent, regardless of the child’s birth status. The Court limited its ruling to inheritance from direct ascendants by representation and did not resolve succession between nonmarital children and collateral relatives in their own right. Filiation must still be proved. The decision is available through the Supreme Court’s Lawphil repository.

Nonmarital children must establish filiation

A child’s birth outside marriage does not erase inheritance rights from the child’s own parents. Article 176 of the Family Code provides that a nonmarital child’s legitime is one-half of a legitimate child’s legitime, with the Civil Code’s other succession rules remaining applicable.

The key issue is often proof of filiation. Relevant evidence may include:

A civil-registry birth record containing a legally effective acknowledgment
A final judgment establishing filiation
A public document or private handwritten instrument signed by the parent expressly recognizing the child
Evidence of open and continuous possession of the status of a child, when legally available
Other evidence allowed under the Family Code, Rules on Evidence, and applicable jurisprudence
DNA evidence when ordered or admitted under the governing rules and circumstances

The available evidence and the deadline for an action can depend on the child’s date of birth, the parent’s date of death, the type of proof relied upon, and transitional rules between the Civil Code and Family Code. If the alleged parent has died or the civil-registry record is disputed, legal advice is urgent.

Who may be excluded from inheritance?

An heir may lose or be prevented from exercising inheritance rights because of:

Valid disinheritance
Incapacity or unworthiness under Articles 1027 and 1032 of the Civil Code
A valid renunciation
Failure to establish the relationship or filiation claimed
Invalidity of the alleged marriage, subject to rules protecting a spouse who contracted marriage in good faith
The effects of a final decree of legal separation on the offending spouse
A legal prohibition affecting a testamentary gift
A prior final judgment, binding settlement, or prescription issue

Unworthiness generally concerns serious conduct specifically identified by law, such as certain crimes or accusations against the decedent, coercion or fraud involving a will, or concealment or alteration of a will. Family disagreement, estrangement, failure to visit, or perceived unfairness is not by itself enough unless it falls within a statutory ground and the required legal conditions are met.

Acceptance, renunciation, and “waivers”

An heir may accept or repudiate an inheritance, but the act must comply with the Civil Code. Acceptance may be express or implied by conduct that necessarily shows an intention to accept. Repudiation must be made in a public or authentic instrument or through a petition presented to the court with jurisdiction over the estate.

Important cautions:

Acceptance or repudiation generally operates from the time of death.
An heir cannot ordinarily accept only the profitable assets while rejecting the burdensome part of the same inheritance.
A renunciation should not be confused with transferring an already inherited share to a selected person.
A waiver made specifically in favor of one or more named heirs may be treated as a donation or other taxable transfer rather than a simple general renunciation.
Selling, mortgaging, assigning, or collecting from inherited property may amount to acceptance.
A creditor may have remedies when an heir repudiates an inheritance to the creditor’s prejudice.

Do not sign a “quitclaim,” “waiver,” or extrajudicial settlement without seeing the inventory, valuations, debts, proposed allocation, and tax consequences.

How an estate may be settled

Extrajudicial settlement

Rule 74 permits an extrajudicial settlement when:

The decedent left no will;
The estate has no outstanding debts;
All heirs are of age, or minors are properly represented by judicial or legal representatives duly authorized for the purpose; and
All affected heirs participate or receive the legally required notice.

The settlement must be in a public instrument. A sole heir may use an affidavit of self-adjudication if that person is truly the only heir. The instrument must be filed with the Register of Deeds when registered property is involved. The fact of settlement must be published once a week for three consecutive weeks in a newspaper of general circulation. A bond equivalent to the value of the personal property covered is required under Rule 74.

The absence of a creditor’s petition for letters of administration for two years after death creates the rule’s presumption that the decedent left no debts. That does not make it safe to conceal known obligations. An extrajudicial settlement does not bind a person who did not participate and had no notice.

Section 4 of Rule 74 also preserves remedies against distributees and the estate within the rule’s two-year period, with special protection for persons under disability. The annotation of a Rule 74 lien or the passage of two years does not necessarily cure fraud, forgery, omitted heirs, lack of notice, or an independently actionable defect.

Judicial settlement or probate

Court proceedings are generally necessary when:

There is a will to probate;
Heirs dispute their identities or shares;
The estate has unresolved debts;
An heir is missing, unrepresented, or legally incapacitated;
Property ownership is disputed;
No valid agreement on partition is possible;
An executor or administrator must collect, preserve, or recover assets; or
The validity of a deed, waiver, sale, donation, marriage, adoption, or filiation is contested.

In estate administration, the court appoints an executor or administrator and issues notice to creditors. Under Rule 86, the court-set period for filing money claims must be at least six months but no more than twelve months from the first publication of the notice. Creditors and estate representatives should act immediately because late claims may be barred, subject only to narrow relief provided by the Rules.

Rule 74 also contains a “summary settlement of estates of small value” procedure whose textual threshold remains ₱10,000 gross value. Because that amount is extremely low and the procedure still requires a court petition, notice, hearing, publication, and possible bond, it is rarely a practical route for modern estates.

Estate tax and transfer requirements

Inheritance rights and estate-tax compliance are related but distinct. Tax payment does not by itself prove that the persons named are the only lawful heirs, and an extrajudicial settlement does not eliminate tax obligations.

For deaths covered by the TRAIN-era rules, the estate tax is generally 6% of the net taxable estate. The return is generally due within one year from death. A return is required for taxable transfers and, regardless of value, when the estate includes registered or registrable property requiring a BIR Certificate Authorizing Registration. Estates with a gross value exceeding ₱5 million generally require the prescribed CPA-certified statement.

Current deductions for a citizen or resident decedent include, when applicable and properly claimed:

A ₱5 million standard deduction
A family-home deduction up to the statutory ₱10 million ceiling, limited to the decedent’s qualifying interest
Valid claims and other deductions allowed by law
The net share of the surviving spouse in community or conjugal property

The date-of-death tax law controls, so older estates may follow different rates, deductions, forms, or amnesty rules. The most recent estate-tax amnesty filing period expired on June 14, 2025; do not assume that an amnesty remains available.

Payment is generally due when the return is filed. Statutory extensions or BIR-approved installment arrangements may be available in qualifying cases, but they are not automatic. Current filing and payment methods should be confirmed with the proper Revenue District Office. The controlling provisions include the TRAIN Law, Republic Act No. 10963, the Ease of Paying Taxes Act, Republic Act No. 11976, and BIR Revenue Regulations No. 12-2018.

After the BIR issues the required electronic Certificate Authorizing Registration, separate registration requirements may still apply to the Register of Deeds, local assessor, Land Transportation Office, corporate secretary, bank, or other custodian.

Practical steps for heirs

Secure the death record. Obtain certified copies from the Philippine Statistics Authority or the proper civil registrar.
Secure the original will. Do not write on it, staple new pages to it, remove pages, or rely only on a scan.
Build a complete family tree. Include every spouse, child, adopted child, nonmarital child, predeceased child and that child’s descendants, parent, and potentially relevant sibling.
Gather civil-status documents. Preserve marriage certificates, birth certificates, adoption orders, annulment or nullity judgments, legal-separation decrees, death certificates, and documents acknowledging filiation.
Inventory the assets. Obtain titles, tax declarations, condominium certificates, vehicle registrations, bank and investment records, corporate records, insurance policies, loan papers, leases, and business books.
Identify the property regime. Determine which assets were exclusive, community, conjugal, co-owned, held in trust, or acquired during a nonmarital union.
Identify debts and expenses. Preserve loan agreements, mortgages, tax notices, hospital and funeral records, judgments, receipts, and communications from creditors.
Document the condition and possession of property. Photograph valuable personal property and real estate. Record who has keys, rents, harvests, records, passwords, vehicles, and business inventory.
Prevent unauthorized transfers. Notify banks, corporations, tenants, property managers, and relevant registries when legally appropriate. Do not impersonate the decedent or use the decedent’s online credentials.
Choose the correct settlement route. Confirm whether Rule 74 is truly available or whether probate or judicial administration is required.
Calendar tax and court deadlines. The one-year estate-tax deadline runs from death. Creditor periods and deadlines to contest instruments may run separately.
Partition only the net estate. Do not divide gross assets before ownership, spouse’s share, debts, taxes, expenses, and legitimes have been resolved.

Evidence worth preserving

Keep originals where possible and make secure copies of:

The original will and previous wills
PSA and civil-registry records
Adoption, guardianship, marriage, annulment, nullity, and legal-separation records
Written acknowledgments of parentage and communications showing family status
Land titles, deeds, tax declarations, surveys, leases, and receipts
Bank, securities, pension, insurance, and business records
Loan, mortgage, guaranty, and tax documents
Prior donations, deeds of sale, waivers, and powers of attorney
Medical records relevant to testamentary capacity, when a will is disputed
Messages, recordings, witness details, and handwriting samples relevant to fraud, coercion, forgery, concealment, or destruction of a will
Proof of rents, withdrawals, sales, transfers, or possession after death

Maintain an asset-and-document log showing who holds each original. Do not secretly alter records or obtain protected account information through unauthorized access.

Common mistakes

Treating the surviving spouse’s ownership share as part of the inheritance
Assuming the eldest child owns or controls the estate
Excluding a nonmarital or adopted child without checking legal proof
Using an affidavit of self-adjudication when more than one heir exists
Signing an extrajudicial settlement without listing every heir
Believing newspaper publication cures the omission of a known heir
Selling a specific estate asset before authority and ownership are settled
Dividing property while debts and taxes remain unpaid
Assuming a handwritten note is automatically a valid will
Ignoring prior donations that may impair legitimes
Confusing a general renunciation with a transfer to a chosen co-heir
Using estate-tax payment as proof of exclusive heirship
Missing the BIR deadline while the family negotiates
Withdrawing from the decedent’s accounts using an old ATM card, password, or power of attorney; a power of attorney generally ends at death
Destroying, hiding, or failing to produce a will

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

Someone is selling, mortgaging, withdrawing, or transferring estate assets
A will has been hidden, destroyed, altered, or suddenly produced
An heir was omitted from a deed or affidavit of self-adjudication
A signature or acknowledgment appears forged
The estate-tax deadline is approaching or has passed
A court has issued notice to creditors
A child’s filiation is disputed and the alleged parent is deceased or seriously ill
There are minor, incapacitated, missing, or overseas heirs
There is a foreign decedent, foreign property, or foreign will
The decedent was a Muslim and the Code of Muslim Personal Laws may apply
The estate includes a business, contested land, agrarian property, corporate shares, substantial debt, or property under litigation
An heir is being pressured to sign a waiver without an inventory or valuation
Testamentary capacity, undue influence, fraud, or unworthiness is alleged

For a decedent of foreign nationality, Article 16 of the Civil Code generally makes the decedent’s national law controlling as to the order and amount of succession and the intrinsic validity of testamentary provisions. Foreign-law proof and Philippine rules on probate, situs, taxation, and registration may still be required.

For covered Muslim Filipinos, succession may be governed by the Code of Muslim Personal Laws, Presidential Decree No. 1083, rather than ordinary Civil Code shares. Do not apply a standard Civil Code inheritance calculator without first resolving which law governs.

Frequently asked questions

Can a parent give everything to only one child?

Not ordinarily if other compulsory heirs survive. A parent may dispose of the free portion, but gifts and will provisions that impair another compulsory heir’s legitime may be reduced. Complete exclusion requires valid disinheritance or another legal basis.

Does the eldest child receive a larger share?

No. Birth order does not create a larger inheritance share under the general Civil Code rules.

Can daughters inherit land equally with sons?

Yes. The ordinary Civil Code rules do not give sons a larger share merely because of sex.

Can a nonmarital child inherit from the father?

Yes, if filiation is legally established and no other legal disqualification applies. The child’s statutory share differs from that of a legitimate child in the combinations specified by law.

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

Usually not by representation, because the nearer-degree heir is preferred. A grandchild may nevertheless inherit under a valid will from the free portion or under another applicable legal rule.

Does a surviving spouse inherit if the couple was separated?

Physical separation alone ordinarily does not end the marriage. A final decree of legal separation and the spouse’s status as the offending or innocent spouse can affect succession rights. Annulment, declaration of nullity, remarriage, and good-faith issues require separate analysis.

Can an heir demand a particular house or lot?

Before partition, heirs generally hold hereditary property in co-ownership rather than owning predetermined physical portions. An heir can demand partition, but cannot unilaterally designate a particular asset as solely theirs unless the will, a valid agreement, or a court-approved partition gives it to them.

Can one co-heir sell inherited property?

A co-heir may generally transfer only the hereditary right or undivided interest that legally belongs to that heir, subject to estate administration, taxes, co-ownership rules, redemption rights, and the outcome of partition. A co-heir cannot sell the other heirs’ shares without authority.

Is there a deadline to settle an estate?

There is no single deadline covering every inheritance claim, but several strict periods may apply. The estate-tax return is generally due within one year from death. Court notices set creditor deadlines. Actions involving fraud, reconveyance, partition, filiation, wills, and Rule 74 settlements may follow different limitation rules. Delay can also cause penalties, lost records, adverse possession arguments, and transfers to third parties.

Must all heirs sign an extrajudicial settlement?

All affected heirs must participate or be properly represented for the agreement to bind them. A deed that omits an heir does not lawfully erase that person’s inheritance rights merely because it was notarized, published, or registered.

Does paying estate tax make someone the legal owner?

No. It satisfies or advances a tax requirement but does not conclusively determine heirship, validate a will, cure a defective settlement, or transfer the shares of omitted heirs.
