Quick answer

Under Philippine law, inheritance passes at the moment of death to the persons named in a valid will and to heirs protected or designated by law. A person cannot freely give away the entire estate if there are compulsory heirs: the law reserves for them a minimum share called the legitime.

The result depends on several facts:

whether the deceased left a valid will;
the deceased’s marital status and property regime;
which children, descendants, parents, spouse, or other relatives survived;
whether filiation, adoption, marriage, or ownership is documented;
whether an heir predeceased, renounced, or is legally disqualified;
the estate’s debts, taxes, and lifetime donations; and
whether property is owned exclusively, conjugally, or jointly with another person.

Being the eldest child, holding the title, paying the funeral expenses, or living on the property does not by itself make someone the sole heir. No heir may simply exclude another heir or sell a specific estate property as though it already belonged exclusively to that heir.

What heirs actually inherit

Inheritance is not automatically everything registered in the deceased’s name. The estate must first be identified and settled.

The usual sequence is:

Determine which property actually belonged to the deceased.
Separate the surviving spouse’s or co-owner’s own share.
Account for enforceable debts, administration expenses, taxes, and other lawful charges.
Determine the heirs and their respective shares.
Apply the will, if valid, without impairing compulsory heirs’ legitimes.
Partition and transfer the net estate.

For example, if a house formed part of the spouses’ absolute community or conjugal partnership, the surviving spouse may already own a share because of the marriage—not because of inheritance. Only the deceased spouse’s portion ordinarily enters the estate, subject to liquidation of the property regime.

Inheritance includes not only assets but also transmissible obligations. Heirs, however, are generally liable for estate obligations only up to the value of property they receive from the estate.

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; and
children classified by the statutes as illegitimate, provided filiation is duly established.

These heirs do not always inherit in equal proportions. Some inherit concurrently, while nearer relatives may exclude more remote relatives except when representation applies.

Brothers, sisters, nephews, nieces, and more distant relatives are generally not compulsory heirs. They may inherit under a will or through intestate succession when the relatives preferred by law are absent.

A parent-in-law, child-in-law, stepchild who was not legally adopted, fiancé, or unmarried partner is not automatically an heir.

Legitimate, legitimated, adopted, and nonmarital children

Legitimate and legitimated children

Legitimate children are compulsory heirs of their parents. Children validly legitimated enjoy the same rights as legitimate children, with legitimation generally retroacting to birth.

A 2025 Supreme Court ruling confirmed that a child’s legitimate status protected by the Family Code is not lost merely because the parents’ marriage is later declared void under Article 36. The Court also explained that failure to annotate legitimation on the birth record does not, by itself, erase substantive rights conferred by law. See Republic v. Tangarorang, G.R. No. 272006, February 5, 2025.

Legally adopted children

A legally adopted person becomes a legitimate child of the adopter and generally has the corresponding successional rights in the adopter’s estate. A private arrangement, long-term care, baptismal record, or use of the family surname does not substitute for a valid adoption order.

Domestic adoption is now primarily administrative under Republic Act No. 11642, which places domestic adoption under the National Authority for Child Care. Older judicial adoptions and rights validly acquired under earlier laws remain protected.

Whether an adoptee may also inherit from biological relatives can depend on the governing adoption law, the date and terms of the adoption, and whether succession is by will or intestacy. The adoption records and order should be reviewed before shares are computed.

Nonmarital children

A child born outside a valid marriage may inherit directly from a biological parent if filiation is established in the manner required by law. The child’s use or non-use of the father’s surname is not, by itself, conclusive of inheritance rights.

Article 176 of the Family Code, as amended by Republic Act No. 9255, recognizes express acknowledgment through the civil-registry birth record, a public document, or the father’s private handwritten instrument. Other legally admissible proof and the applicable periods for establishing filiation may become important when acknowledgment is disputed.

As a general rule, a nonmarital child’s legitime is one-half of the legitime of a legitimate child, subject to the estate available and the rights of other compulsory heirs. That formula should not be applied mechanically without identifying every concurrent heir.

Grandchildren and representation

Grandchildren ordinarily do not inherit by representation while their own parent—the deceased’s child—is alive and qualified to inherit. Representation may operate when that parent predeceased the decedent, is incapacitated to inherit, or was disinherited in a legally effective manner. Renunciation alone does not always produce the same result.

The Supreme Court has construed Article 992 so that children, regardless of the circumstances of birth, may inherit from direct ascendants such as grandparents by right of representation. See Aquino v. Aquino, G.R. Nos. 208912 and 209018, December 7, 2021. Questions involving collateral relatives or inheritance in one’s own right remain fact-sensitive and should not be resolved by assuming that every blood relative has the same entitlement.

Rights of the surviving spouse

A surviving spouse is generally both a compulsory heir and an intestate heir. The share varies according to the other surviving heirs.

Important qualifications include:

The marriage must be legally recognized.
Mere physical separation does not automatically end inheritance rights.
A spouse found guilty in a decree of legal separation may lose succession rights under the Family Code.
A spouse who caused or procured a defective will or committed another statutory act of unworthiness may be disqualified.
The spouse’s share from liquidation of the marriage property is separate from the spouse’s inheritance.

A boyfriend, girlfriend, or live-in partner does not become an heir merely because the relationship was long-term or they had children together. The partner may nevertheless have an ownership claim over property acquired through actual contributions or under the co-ownership rules applicable to unions without marriage. That ownership must be determined before the estate is divided.

What happens when there is a will?

A will controls only to the extent allowed by law. It must comply with the formal and substantive requirements applicable to it and must be allowed in probate before it can transmit property as a will.

Even if a will says “I leave everything to X,” compulsory heirs may still claim their legitimes. The freely disposable portion is what remains after all legitimes are protected.

A will may fail, wholly or partly, because of matters such as:

lack of testamentary capacity;
noncompliance with required formalities;
forgery, fraud, duress, or undue influence;
institution of an heir for an unlawful or impossible purpose;
preterition of a compulsory heir in the direct line;
an ineffective attempt to disinherit someone; or
dispositions exceeding the portion the testator could freely give.

The person holding a will must deliver it to the court having jurisdiction within 20 days after learning of the testator’s death. A named executor who knows of the nomination must present the will, if in that person’s possession, or signify acceptance or refusal within the period stated in Rule 75 of the Rules of Court on special proceedings.

Do not destroy, conceal, alter, staple, mark, or “correct” an original will.

Can a parent disinherit a child?

Not merely because the parent is angry, estranged, or prefers another child.

A compulsory heir may be disinherited only for a cause expressly recognized by law, stated in a valid will, and attributable to the person disinherited. If the heir disputes the cause, the persons benefiting from the disinheritance may have to prove it.

A statement such as “I gave this child nothing because we no longer speak” does not necessarily satisfy the legal requirements. If disinheritance is invalid, the affected heir may still recover the legitime.

What if there is no will?

When a person dies without a valid will—or when the will does not dispose of the whole estate—the Civil Code’s rules on intestate succession apply.

In broad terms, the law gives priority to:

children and descendants;
parents and ascendants, if no descendants entitled to inherit survive;
the surviving spouse, alone or together with certain heirs;
recognized nonmarital children under the applicable concurrence rules;
brothers, sisters, nephews, and nieces in the situations specified by law;
other collateral relatives within the degree allowed by law; and
the State, if no qualified heir exists.

This is only an order of preference, not a universal share calculator. The surviving spouse and nonmarital children may concur with other heirs, and representation may change who receives a particular branch’s share.

How legitimes and shares are computed

The Civil Code does not compute inheritance by simply dividing every listed asset by the number of relatives.

The calculation ordinarily requires:

valuing the property left at death;
deducting obligations and charges that the law allows;
adding back certain lifetime donations for purposes of computation;
identifying compulsory heirs and concurrence rules;
calculating each legitime;
determining the disposable portion;
reducing donations or testamentary gifts that impair legitimes; and
allocating divisible and indivisible assets during partition.

Lifetime gifts to compulsory heirs may need to be brought into the computation through collation, unless a valid exception applies. Calling a transfer a “sale” does not end the inquiry if the alleged price was never paid or the transaction was simulated.

Because a small change in family status can materially change every share, use certified records and a complete family tree before relying on a percentage.

When an heir may be excluded

An heir does not lose inheritance rights merely because the heir:

lived abroad;
did not care for the deceased;
did not pay funeral costs;
is financially better off;
is a daughter rather than a son;
is younger than another heir;
married against the family’s wishes; or
was omitted from an extrajudicial settlement without notice.

Exclusion requires a legal basis, such as:

valid disinheritance;
incapacity or unworthiness under the Civil Code;
valid repudiation of the inheritance;
absence of legally required filiation;
a prior binding settlement, judgment, or prescription applicable to the specific claim; or
proof that the claimant is not an heir.

Causes of unworthiness include certain grave acts against the deceased or the deceased’s family, accusations of serious crimes under specified circumstances, coercion concerning a will, and concealment or alteration of a will. Application of these provisions is document- and fact-dependent.

Acceptance and repudiation

An heir may accept or repudiate an inheritance only after the person from whom the inheritance comes has died. Acceptance may be express or implied by acts that necessarily show an intention to accept.

Repudiation must comply with the Civil Code’s formal requirements. An informal family message saying “I do not want anything” may not be enough. An heir should not sign a waiver, quitclaim, deed of sale, or extrajudicial settlement without understanding whether the document:

repudiates the entire inheritance;
transfers the share to selected relatives;
constitutes a donation or taxable transfer; or
acknowledges facts that may later be difficult to dispute.

Creditors may have remedies when an heir repudiates an inheritance to their prejudice.

Rights before partition

From death until partition, the heirs generally own the inheritance in common, subject to administration and settlement of the estate.

Before partition:

An heir may generally transfer only the hereditary interest the heir actually owns.
A co-heir cannot unilaterally select and sell a particular house, lot, or room as exclusively theirs.
A buyer from one heir may acquire only whatever hereditary interest that seller ultimately receives.
Exclusive possession by one heir does not automatically extinguish the others’ rights.
Income, rent, crops, and necessary expenses should be documented and accounted for.
Estate property should not be hidden, demolished, withdrawn, or transferred without lawful authority.

A sale of an heir’s hereditary right to a stranger may also trigger statutory rights of the other co-heirs, including a possible right of redemption within the period and under the conditions fixed by Article 1088 of the Civil Code. Prompt legal advice is essential because the period is short and depends on written notice.

Extrajudicial settlement: when it is available

Under Rule 74, heirs may generally settle an estate extrajudicially when:

the deceased left no will;
the estate has no outstanding debts for purposes of the rule;
all heirs participate;
all heirs are adults, or minors are properly represented by judicial or legal representatives duly authorized for the purpose; and
the settlement is made in the required public instrument, filed with the Register of Deeds when applicable, and published as required.

If there is only one heir, that person may use an affidavit of self-adjudication, but only if the claim of being the sole heir is true.

Publication does not cure the deliberate or accidental 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. The rule also contains a two-year framework protecting creditors and persons unduly deprived of participation, but it should not be treated as a universal deadline barring every omitted-heir or ownership claim. The remedy and prescriptive period depend on the fraud alleged, the relief sought, registration, notice, possession, and other facts.

Judicial settlement is usually appropriate when there is a will, unresolved debt, disputed heirship, a missing or unwilling heir, contested ownership, a need to appoint an administrator, or disagreement that prevents a lawful extrajudicial settlement.

Estate proceedings and creditor claims

Judicial estate proceedings are generally filed in the proper court of the province or city where the deceased resided at death. Special rules apply to nonresidents with property in the Philippines.

After the court issues notice to creditors, the period for filing money claims must be at least six months but not more than twelve months from the date of first publication, as fixed by the court under Rule 86. Creditors should not assume that private negotiations suspend this deadline.

Administration and probate procedure is governed primarily by Rules 73 to 91 of the Rules of Court.

Estate tax and transfer requirements

Inheritance rights and estate-tax compliance are related but distinct. A person may be an heir even though the estate has not yet paid its tax, but registration and transfer of assets ordinarily require tax clearance and other documents.

For deaths covered by the TRAIN-law estate-tax rules:

the estate tax rate is generally 6% of the net taxable estate;
the estate-tax return is generally due within one year from death;
the estate must secure its own taxpayer identification number;
filing and payment are generally made through the BIR office or authorized channel having jurisdiction under current BIR rules; and
transfer of registered property ordinarily requires a BIR electronic Certificate Authorizing Registration or other applicable clearance.

The BIR may allow an extension to pay, installment arrangements, or approved partial disposition in situations and under conditions provided by law and regulations. These are not automatic. Late filing or payment may result in surcharge, interest, and compromise penalties.

Requirements can differ according to the date of death, citizenship or residence of the deceased, property type, estate value, and later tax legislation. Check the BIR’s current Estate Tax guidance and Revenue Regulations No. 12-2018 before filing.

Practical steps for heirs

1. Secure the basic records

Obtain certified copies where available:

PSA death certificate;
PSA marriage certificate;
birth certificates of all children;
adoption, legitimation, acknowledgment, or filiation records;
the original will and codicils;
court judgments affecting marriage, filiation, adoption, or legal separation; and
death certificates of predeceased children, parents, or other relevant relatives.

2. Build a complete family tree

List every possible spouse, child, adopted child, nonmarital child, parent, and predeceased descendant. Record dates of birth, marriage, death, and adoption. Do not omit a person merely because the family disputes the relationship.

3. Inventory assets and liabilities

Preserve copies of:

land titles, tax declarations, and deeds;
condominium and vehicle records;
bank, investment, pension, insurance, and business documents;
loan statements, mortgages, tax liabilities, and receipts;
proof of ownership contributions by the surviving spouse or partner;
leases and records of rent collected;
prior donations, advances, or purported sales to heirs; and
digital-asset and online-account information.

Do not access a deceased person’s account by using credentials without proper authority.

4. Protect the property

Photograph valuable assets, record who has custody, notify banks and relevant institutions through lawful channels, maintain necessary insurance, and keep receipts for preservation expenses. Avoid distributing cash or personal property before debts, taxes, and competing claims are assessed.

5. Determine the proper settlement route

Use probate or judicial administration when legally required. Consider extrajudicial settlement only after confirming that all Rule 74 conditions are present and every heir has been identified and included.

6. Obtain tax and registration requirements

Confirm the applicable BIR checklist, local transfer tax, Registry of Deeds requirements, assessor’s requirements, and institution-specific documents. Do not rely on an old checklist because forms and filing channels can change.

7. Sign only a complete and accurate instrument

The settlement should identify all heirs, assets, liabilities, allocations, and material conditions. Each signatory should receive a complete copy. Blank pages, unexplained waivers, and side agreements are serious warning signs.

Evidence to preserve when inheritance is disputed

Keep original documents and secure copies of:

wills, envelopes, notarial records, and handwriting samples;
birth, marriage, death, and adoption records;
written acknowledgment of parentage;
titles and certified title histories;
bank statements and withdrawal records;
deeds, receipts, tax filings, and proof of payment;
messages about ownership, donations, waivers, or concealment;
proof of possession and improvements;
publication notices and entire newspaper pages;
Registry of Deeds annotations;
medical records relevant to testamentary capacity, obtained lawfully; and
names and contact details of disinterested witnesses.

Preserve electronic files in their original form, including metadata where possible. Screenshots alone may omit information needed to authenticate a communication.

Common mistakes

Dividing property before separating the surviving spouse’s or co-owner’s share.
Assuming all children automatically receive identical shares.
Treating a tax declaration as conclusive proof of ownership.
Using an affidavit of self-adjudication despite the existence of other heirs.
Publishing an extrajudicial settlement and assuming publication cures an omitted heir.
Selling a specific estate asset before partition without authority.
Ignoring an acknowledged or legally provable nonmarital child.
Assuming a live-in partner is a spouse or has no possible ownership claim.
Relying on a photocopy while the original will is missing.
Distributing bank deposits without accounting for debts and taxes.
Signing a waiver without understanding its tax and property consequences.
Waiting until property has been sold to third parties before objecting.
Applying today’s tax rules to a death that occurred under an earlier tax regime.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

a will may be hidden, forged, altered, or destroyed;
someone is withdrawing funds or selling estate property;
an heir was omitted from a settlement or affidavit of self-adjudication;
filiation, adoption, marriage, or legitimacy is disputed;
a minor, incapacitated person, absentee, or overseas heir is involved;
the family cannot agree on an administrator or partition;
estate property is being foreclosed, occupied, demolished, or transferred;
a co-heir sold a hereditary interest to an outsider;
the estate-tax deadline is approaching or has passed;
a creditor-claim period has been published;
there are properties or heirs in more than one country; or
you are being pressured to sign immediately.

Qualified indigent persons may ask the Public Attorney’s Office about eligibility for legal assistance. Court filings remain subject to jurisdictional and procedural requirements.

Frequently asked questions

Can a parent leave everything to only one child?

Usually not if other compulsory heirs survive. The favored child may receive the disposable portion, but the other compulsory heirs may demand completion of their legitimes.

Do daughters and sons have equal inheritance rights?

Sex and birth order do not give a child a larger share. Differences arise from legal status, representation, adoption, concurrence with other heirs, valid testamentary provisions, and other statutory rules—not from being male, female, eldest, or youngest.

Can an illegitimate child inherit from the father?

Yes, if filiation is duly established. The share is determined under the legitime or intestacy rules and may differ from that of a legitimate child.

Can grandchildren inherit while their parent is alive?

Ordinarily, a nearer descendant excludes the more remote descendant. Grandchildren may inherit independently under a will’s disposable portion, or by representation when the statutory requirements are present.

Does a live-in partner inherit automatically?

No. An unmarried partner is not a surviving spouse for compulsory or intestate succession. The partner may still prove ownership of a share in jointly acquired property under the applicable co-ownership rules.

Does the person named on the land title own the whole property?

Not necessarily. Registration is powerful evidence, but claims based on the marriage property regime, co-ownership, trust, simulation, fraud, or succession may require examination of the acquisition documents and title history.

Can one heir live in or rent out estate property?

An heir may possess common property subject to the equal rights of the other co-heirs. Exclusive use, rental, and collection of income may require consent and accounting. One heir cannot treat common estate property as exclusively owned before lawful partition.

Can an heir refuse an inheritance?

Yes, but repudiation must occur after death and comply with the Civil Code’s formal requirements. It can have tax, creditor, and family consequences.

Is an extrajudicial settlement valid without every heir’s signature?

It does not bind an heir who neither participated nor had the legally relevant notice. Omission can also affect later titles and transfers. The precise remedy should be assessed immediately.

Is there one deadline for all inheritance cases?

No. Different periods apply to estate-tax filing, presenting a will, creditor claims, redemption, attacks on settlements or deeds, recovery of property, and other remedies. The correct period depends on the cause of action and when notice, registration, possession, or fraud occurred.
