Quick answer

In the Philippines, an heir’s rights depend on four questions: Who died, what property actually belonged to that person, whether a valid will exists, and which relatives survived. Children, a surviving legal spouse, and—in the absence of legitimate descendants—legitimate parents or ascendants may be compulsory heirs whose reserved shares, called legitimes, generally cannot be taken away by a will.

If there is no valid will, the Civil Code determines both the order of heirs and their shares. Ownership rights arise at death, but heirs may not simply divide, sell, or take estate assets without first accounting for the surviving spouse’s property, estate debts, taxes, and the proper settlement procedure. The governing rules are principally in the Civil Code of the Philippines, the Family Code, and the Rules of Court on settlement of estates.

Inheritance begins with the estate—not with the family’s assumptions

Succession transmits the decedent’s property, transmissible rights, and obligations from the moment of death. Liability for the decedent’s obligations is limited to the value of the inheritance.

Before anyone computes an heir’s percentage, the estate must be identified correctly:

Determine which assets belonged exclusively to the decedent.
If the decedent was married, liquidate the applicable absolute community, conjugal partnership, or separation-of-property regime.
Return the surviving spouse’s own share and any required reimbursements.
Deduct estate debts, charges, administration expenses, and taxes.
Add collatable lifetime donations when the law requires them to be considered in computing legitimes.
Apply the will, if valid, and the rules on compulsory or intestate succession.

For example, a house titled in the decedent’s name is not automatically 100% part of the estate. It may be community or conjugal property. Conversely, property inherited by the decedent during marriage may be exclusive, depending on the property regime and documents.

Under Articles 103 and 130 of the Family Code, if no court settlement is opened, the surviving spouse must liquidate community or conjugal property judicially or extrajudicially within six months from death. A later disposition or encumbrance involving unliquidated common property may be void.

The three ways a person may become an heir

Compulsory heirs

Compulsory heirs are persons for whom the law reserves a legitime. Depending on the family configuration, they include:

Legitimate children and descendants;
In their absence, legitimate parents and ascendants;
The surviving legal spouse; and
Children classified by law as illegitimate or nonmarital, provided filiation is duly established.

A person may belong to more than one category of heir. A child named in a will, for example, may be both a compulsory and testamentary heir.

Testamentary heirs

These are heirs named in a valid will. A testator with compulsory heirs may generally dispose only of the portion remaining after all legitimes have been protected. A testator without compulsory heirs may leave the estate to any person legally capable of inheriting.

A will does not transfer property merely because the family accepts it as genuine. Article 838 of the Civil Code and Rule 75 require the will to be proved and allowed by the proper court.

Legal or intestate heirs

These heirs inherit by operation of law when:

There is no will;
The will is void or has lost its validity;
The will covers only part of the estate;
A named heir predeceases the testator, repudiates the inheritance, or is incapable of inheriting, and no substitution, representation, or accretion resolves the vacancy; or
A testamentary provision otherwise fails.

Intestacy can therefore cover the whole estate or only the property not effectively disposed of by the will.

Legitimes when there is a will

A legitime is calculated from the hereditary estate: generally the value of the property left at death, less qualifying debts and charges, with collatable donations added when required.

The principal rules include:

Legitimate children or descendants: collectively entitled to one-half of the hereditary estate, normally divided equally by family branch where representation applies.
Legitimate parents or ascendants: in the absence of legitimate descendants, collectively entitled to one-half.
Each nonmarital child: generally entitled to one-half of the legitime of a legitimate child, subject to the Civil Code’s rules protecting the surviving spouse and limiting claims against the disposable portion.
Surviving spouse with one legitimate child: spouse’s legitime is one-fourth.
Surviving spouse with two or more legitimate children: spouse receives the same legitime as one legitimate child.
Surviving spouse with legitimate ascendants: spouse’s legitime is one-fourth.
Surviving spouse with only nonmarital children: spouse receives one-third; the children collectively receive another third.
Surviving spouse alone: ordinarily entitled to one-half, subject to the special rule for certain marriages solemnized when a spouse was at the point of death.

Other combinations have special fractions. A reliable computation must account for the number and status of every child, any predeceased branch, the surviving spouse, ascendants, lifetime donations, and the wording of the will.

A will that gives a compulsory heir less than the correct legitime may be reduced to satisfy that heir. Total and unintentional omission of a compulsory heir in the direct line—known as preterition—can annul the institution of heirs, although valid devises and legacies may remain effective to the extent they do not impair legitimes.

Common intestate shares

The following are common outcomes after marital-property liquidation, debts, expenses, and taxes. “Children” in this table includes proper representation by descendants where applicable.

Survivors	General intestate distribution
Legitimate children only	Equal shares
Legitimate children and surviving spouse	Spouse receives the same share as each legitimate child
Legitimate and nonmarital children, no spouse	Each nonmarital child generally receives one-half of the share of each legitimate child
Legitimate children, nonmarital children, and spouse	Each legitimate child and the spouse receives two units for every one unit received by each nonmarital child
Surviving spouse and nonmarital children only	One-half to the spouse; one-half collectively to the children
Legitimate parents or ascendants and spouse, with no descendants	One-half to the ascendants; one-half to the spouse
Legitimate ascendants and nonmarital children, no spouse	One-half to the ascendants; one-half collectively to the children
Legitimate ascendants, spouse, and nonmarital children	One-half to the ascendants; one-fourth to the spouse; one-fourth collectively to the children
Spouse and brothers, sisters, nephews, or nieces, with no descendants or ascendants	One-half to the spouse; one-half to the qualifying collateral relatives
Brothers and sisters only	Equal shares if all are full-blood siblings
Full- and half-blood siblings together	A full-blood sibling receives twice the share of a half-blood sibling
No closer qualified heir	Other collateral relatives may inherit up to the fifth degree; otherwise, the State

Special rules apply when the decedent was a nonmarital child. For example, if such a decedent dies without descendants, a duly proved father or mother generally succeeds ahead of the spouse under Articles 993 and 994. The spouse succeeds in default of the parents, subject to the rights of qualifying siblings, nephews, and nieces. This is one reason a generic “family percentage calculator” can produce a wrong result.

Children have equal rights regardless of sex, age, or marriage order

There is no legal preference for:

Sons over daughters;
The eldest child over younger children;
A child from the first marriage over a child from a later valid marriage; or
The child who lives in or manages the family home.

Caregiving, paying household expenses, or managing property does not by itself increase an intestate share. A caregiver may, however, have a separate documented claim for reimbursement, compensation, ownership, or credit against the estate. That claim must be proved and should not be confused with inheritance.

Rights of nonmarital children

A nonmarital child may inherit directly from either parent once filiation is established. Article 176 of the Family Code generally fixes the child’s legitime at one-half of that of a legitimate child.

Filiation may be shown through evidence recognized by Articles 172 and 175, including:

A record of birth in the civil register;
A final judgment;
An admission of filiation in a public document;
A private handwritten instrument signed by the parent;
Open and continuous possession of the status of a child; or
Other evidence allowed by the Rules of Court and special laws.

The applicable filing period depends on the kind of evidence and when the persons involved were born or died. A claim relying on open and continuous possession of status or secondary evidence may have to be brought during the alleged parent’s lifetime. Older cases may also involve vested rights under the former Civil Code. Anyone facing an unrecorded or disputed filiation should obtain legal advice immediately rather than wait for the estate settlement.

Representation through a parent

The Supreme Court’s 2021 decision in Aquino v. Aquino, G.R. Nos. 208912 and 209018 reinterpreted Article 992. A nonmarital grandchild may represent a deceased parent in the estate of a direct ascendant, such as a grandparent, regardless of the circumstances of the grandchild’s birth.

The ruling is limited:

It concerns succession in the direct line by representation;
The grandchild must still prove filiation;
The grandchild receives only the branch share the parent would have received; and
The Court did not abolish every restriction under Article 992 involving inheritance in one’s own right or collateral relatives.

Adopted and legitimated children

A legitimated child enjoys the same rights as a legitimate child, with the effects of legitimation generally relating back to birth.

Under Sections 41 and 43 of the Domestic Administrative Adoption and Alternative Child Care Act, Republic Act No. 11642, an adoptee is the legitimate child of the adopter for all purposes. The adoptee and adopter have reciprocal testate and intestate succession rights without distinction from legitimate filiation. The filiation created by adoption also extends as the statute provides to the adopter’s parents, legitimate siblings, and legitimate descendants.

Except in a stepparent adoption where the biological parent is the adopter’s spouse, adoption generally severs legal ties with the biological parents. Testamentary rights and any later rescission of adoption require separate examination under the statute.

Surviving spouses and unmarried partners

A surviving spouse ordinarily means a person in a legally valid marriage to the decedent. Physical separation alone does not automatically end inheritance rights.

Different rules may apply when:

A final decree of legal separation exists;
The surviving spouse caused the legal separation;
The marriage was void or annulled;
A previous marriage was still subsisting;
A foreign divorce or judgment is involved; or
The marriage’s validity is being challenged.

An unmarried or live-in partner is not a compulsory heir merely because the relationship was long-term or they had children together. The partner may own a separate or co-owned share under property law and may potentially receive from the disposable portion under a valid will, if legally qualified. Ownership rights and inheritance rights must be analyzed separately.

When grandchildren inherit

Grandchildren do not automatically share equally with living children of the decedent. Normally, the nearer relative excludes the more distant one.

Representation commonly occurs when the person through whom the grandchild claims:

Died before the decedent;
Was validly disinherited; or
Was incapable or unworthy to inherit.

The descendants divide per stirpes, meaning by family branch. If a predeceased child would have received one-fourth, that child’s three qualified children divide that one-fourth; they do not each receive one-fourth of the whole estate.

An heir who voluntarily repudiates their own share generally cannot be represented for that repudiated share. This differs from a representative who previously renounced an inheritance coming from the parent they now represent.

A parent cannot disinherit a child merely by saying so

A compulsory heir loses a legitime through disinheritance only when:

The disinheritance is made in a valid will;
The will identifies a legal cause expressly recognized by the Civil Code; and
If the heir denies the cause, the other heirs prove it.

For children or descendants, statutory causes include specified forms of attempted killing, false serious accusation, adultery or concubinage with the testator’s spouse, coercion concerning a will, unjustified refusal of support, maltreatment by word or deed, a legally qualifying dishonorable life, and conviction carrying civil interdiction.

Family disappointment, marrying against a parent’s wishes, choosing a different career, moving away, or ordinary quarrels are not automatically statutory grounds. Reconciliation may remove the right to disinherit or make an earlier disinheritance ineffective.

Even when a parent is validly disinherited, that parent’s children or descendants may take the parent’s place as compulsory heirs regarding the legitime.

Unworthiness is different from disinheritance

Article 1032 makes certain persons incapable of inheriting because of unworthiness. Examples include specified convictions or conduct involving an attempt on the decedent’s life, a groundless serious accusation, coercion or fraud affecting a will, concealment or alteration of a will, and forgery of a supposed will.

Some grounds require a final judgment. The decedent may also neutralize a cause of unworthiness by making a will with knowledge of it or later condoning it in writing.

An action to declare incapacity and recover the inheritance generally must be brought within five years from the time the disqualified person took possession. Urgent legal advice is warranted if an allegedly unworthy heir is selling or collecting estate assets.

Heirs inherit only what remains after lawful obligations

The estate must satisfy valid obligations before final distribution. Heirs are not personally required to pay the decedent’s debts beyond the value they inherit merely because they are children or relatives. They may nevertheless be independently liable if they were co-borrowers, guarantors, mortgagors, or recipients of improperly distributed estate assets.

In a judicial settlement, the court sets a claims period of not less than six months nor more than twelve months from the first publication of notice to creditors. Contractual money claims, funeral and last-illness expenses, and money judgments generally must be filed within the court’s period, subject to the limited exceptions in Rule 86.

A will must be brought to court

A family cannot bypass probate by executing an extrajudicial settlement while knowingly ignoring a will.

Under Rule 75:

The person holding the will must deliver it to the proper court or named executor within 20 days after learning of the testator’s death.
The named executor must, within the applicable 20-day period, present the will to the court and state whether the appointment is accepted or refused.

A foreign-probated will affecting assets in the Philippines ordinarily must still be allowed through the Philippine procedure under Rule 77.

Possible grounds for disallowing a will include failure to follow required formalities, lack of testamentary capacity, duress, fear, threats, improper pressure or undue influence, fraud in obtaining the signature, or lack of intent that the document operate as a will.

Extrajudicial settlement is allowed only in a proper case

Under Rule 74, heirs may generally settle without appointing an administrator when:

The decedent left no will;
The estate has no outstanding debts;
All heirs are of age, or minors are represented by duly authorized judicial or legal representatives; and
The heirs agree on the settlement.

The settlement must be in a public instrument. A sole heir may use an affidavit of self-adjudication. The instrument must be filed with the Register of Deeds when registered property is involved. The Rules also require publication once a week for three consecutive weeks and a bond corresponding to the value of personal property covered by the settlement.

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

Rule 74 provides a two-year procedure for certain claims by creditors and persons deprived of lawful participation, and keeps the bond and real estate charged during that period. But the two-year provision is not a safe basis for assuming that an omitted heir who never participated or received notice has permanently lost all remedies. Prescription, fraud, notice, possession, and the relief sought must be examined individually.

When court settlement is necessary

Judicial probate or administration is usually required when:

There is a will;
Heirs dispute their identities or shares;
Filiation or marriage is contested;
The estate has unresolved debts;
A minor’s interests cannot be handled through an authorized representative;
Someone concealed, transferred, or dissipated property;
The validity of a deed, donation, waiver, or will is disputed;
Heirs cannot agree on partition; or
Court authority is needed to sell estate property.

Proceedings are generally filed where the decedent resided at death. For a nonresident decedent, venue may lie where Philippine estate property is located. Under Republic Act No. 11576, first-level courts have probate jurisdiction where the estate value does not exceed ₱2 million; the Regional Trial Court handles estates exceeding that threshold.

Estate tax and transfer requirements

For deaths governed by the TRAIN-era rules, the estate tax is generally 6% of the net taxable estate. The estate tax return is generally due within one year from death. A return may still be required even when no tax is payable if the gross estate exceeds the statutory threshold or contains registered or registrable property requiring a BIR clearance.

A return showing a gross estate exceeding ₱5 million must generally be supported by the required CPA-certified statement. The BIR may approve limited extensions or installment arrangements in qualifying cases; these are not automatic.

The BIR’s estate-tax regulations and BIR Form 1801 instructions should be checked against the date of death because rates, deductions, forms, and documentary requirements have changed over time. An electronic Certificate Authorizing Registration, or eCAR, is normally needed before registered assets can be transferred.

The estate-tax amnesty filing window ended in June 2025. It should not be treated as a continuing remedy for a new late filing. BIR Revenue Memorandum Circular No. 33-2026 concerns issues such as proof of settlement and payment for timely amnesty availments; it did not reopen the amnesty.

Evidence heirs should preserve

Secure originals or certified copies where possible:

PSA death, birth, and marriage certificates;
Adoption orders and amended civil-registry records;
All wills, codicils, envelopes, drafts, and safe-deposit information;
Samples of the decedent’s handwriting if a holographic will is involved;
Transfer certificates of title, condominium titles, tax declarations, and deeds;
Bank, investment, pension, insurance, and loan records;
Corporate records, stock certificates, partnership documents, and business ledgers;
Marriage settlements and documents showing the source of funds used to acquire property;
Receipts for funeral, medical, preservation, repair, and estate expenses;
Records of lifetime donations and advances to heirs;
Leases, rent collections, crop proceeds, and other income received after death;
Messages, letters, remittance records, photographs, school records, and other legally obtained evidence relevant to filiation;
Copies of any waiver, partition, affidavit of self-adjudication, deed of sale, or special power of attorney; and
Certified title histories and notarial details for suspicious transfers.

Preserve digital files in their original form and retain metadata. Do not access protected accounts, remove property, fabricate acknowledgments, or obtain biological samples unlawfully.

Practical steps for heirs

Build a complete family tree. Include every spouse, child, adopted child, predeceased child and descendant, and potentially relevant parent or sibling.
Find and protect any will. Do not alter, staple, annotate, or discard it. Observe Rule 75’s 20-day delivery requirement.
Prepare a neutral inventory. Record each asset, estimated value, titleholder, source of acquisition, debt, income, and current possessor.
Classify marital and exclusive property. Do this before calculating inheritance shares.
Secure the property without appropriating it. Preserve records, collect rent into an accountable estate fund, maintain necessary insurance, and document urgent repairs.
Identify creditors and tax deadlines. Start the BIR process early even if the heirs are still negotiating the partition.
Choose the correct settlement route. Use an extrajudicial settlement only when all Rule 74 conditions genuinely exist.
Calculate shares from documents, not assumptions. Include legitimes, representation, collatable donations, and any valid testamentary dispositions.
Require a written accounting. Any heir handling money, crops, rent, or business income should disclose receipts and expenses.
Execute and register the partition properly. Pay required taxes, obtain the eCAR and local clearances, and comply with the Register of Deeds and each institution holding an asset.

Common mistakes

Dividing the gross property before returning the surviving spouse’s share;
Treating the eldest child as the family’s legal owner or automatic administrator;
Excluding a nonmarital child without examining filiation evidence;
Giving grandchildren equal shares with living children instead of applying representation;
Assuming a handwritten list is automatically an enforceable will;
Using an affidavit of self-adjudication despite the existence of other heirs;
Believing newspaper publication alone binds a deliberately omitted heir;
Selling a specific estate property based on one heir’s signature;
Confusing possession of a title or owner’s duplicate certificate with exclusive ownership;
Treating payment of taxes as proof that the payer owns the estate;
Signing a “waiver” without understanding that it may constitute acceptance, donation, sale, or repudiation;
Ignoring lifetime donations that may affect legitimes; and
Waiting until property is transferred to third parties before asserting an objection.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

A will is missing, damaged, concealed, or suspected to be forged;
Someone is about to sell, mortgage, withdraw, or transfer estate assets;
An heir was omitted from a settlement or publication;
Filiation is disputed or was never formally recorded;
There are children from different relationships or marriages;
The marriage, divorce, annulment, or legal separation is disputed;
A compulsory heir was omitted or disinherited;
A minor, incapacitated person, absentee, or overseas heir is involved;
The decedent or major assets are outside the Philippines;
There are significant debts, businesses, corporate shares, agricultural land, or ancestral property;
An estate-tax deadline has passed; or
An heir is being pressured to sign a waiver, sale, quitclaim, or partition.

Qualified persons who cannot afford private counsel may ask the Public Attorney’s Office whether they meet its legal-assistance requirements.

Frequently asked questions

Can a parent leave everything to only one child?

Usually not if there are other compulsory heirs. The favored child may receive a legitime plus some or all of the disposable portion, but testamentary gifts must be reduced if they impair another compulsory heir’s legitime.

Does the eldest child receive a larger share?

No. Age and birth order do not create a larger inheritance share.

Can an heir demand a share while the parent is alive?

No one has a vested inheritance in the estate of a living person. A compromise or renunciation concerning a future legitime is generally void. Present ownership rights arising from a valid donation, sale, trust, or co-ownership are different matters.

Does a child using the mother’s surname lose inheritance rights from the father?

No. The surname is not the controlling issue. The child must establish filiation through evidence recognized by law.

Can a live-in partner inherit?

Not automatically as a surviving spouse. The partner may have separate ownership or co-ownership rights and may receive property under a valid will from the disposable portion if legally qualified.

Can one heir sell inherited land without the others?

Before partition, an heir may generally deal only with the hereditary or undivided interest that legally belongs to that heir. One heir cannot validly convey the other heirs’ shares or guarantee that a specific estate parcel exclusively belongs to the seller.

Can an heir refuse an inheritance?

Yes. Repudiation must be made in a public or authentic instrument or by a petition filed in the estate proceeding. It is generally irrevocable. Parents or guardians need judicial authorization to repudiate an inheritance belonging to a minor or ward.

Do heirs inherit the decedent’s unpaid loans?

Estate assets answer for valid debts. Heirs do not become personally liable beyond the value inherited solely because of their relationship, unless they have a separate legal obligation or received assets subject to recovery.

Is an extrajudicial settlement valid without publication?

Publication is a Rule 74 requirement. Failure to publish can prevent the settlement from binding creditors and persons who did not participate or receive notice, even if the signatories remain bound by their own acts.

Which law applies if the decedent was a foreign citizen?

Article 16 of the Civil Code generally makes the decedent’s national law govern the order of succession, the amount of successional rights, and the intrinsic validity of testamentary provisions, regardless of where the property is located. Philippine procedure, registration, taxation, and property rules may still apply to Philippine assets. Cross-border estates require advice based on the decedent’s citizenship, residence, will, and asset locations.
