Quick answer

An heir’s share depends on four questions: Was there a valid will? Who survived the deceased? Which property actually belonged to the deceased? What debts, taxes, and prior donations must first be accounted for?

Philippine law protects certain compulsory heirs through a reserved minimum share called the legitime. A will cannot validly deprive them of that share unless there is a legally sufficient disinheritance. If there is no valid will—or the will does not dispose of the entire estate—the rules on intestate succession determine who inherits and in what proportions.

Inheritance rights arise at death, but heirs do not simply divide the deceased’s gross property. The marital property regime must first be liquidated, estate obligations and taxes addressed, and the proper settlement process completed. Until partition, the heirs generally hold the net estate in common, subject to its debts. These principles come primarily from the Civil Code of the Philippines, the Family Code, and the Rules of Court on estate settlement.

Start with the net estate—not the property’s gross value

The amount available for inheritance is not necessarily everything registered in the deceased’s name.

Before computing shares:

Identify which assets were exclusively owned by the deceased and which were community, conjugal, or co-owned property.
Liquidate the applicable marital property regime. The surviving spouse’s own share in community or conjugal property is not an inheritance.
Include only the deceased’s interest in jointly owned property.
Account for enforceable debts, mortgages, taxes, administration expenses, and other lawful estate obligations.
Review lifetime donations or advances that may have to be collated or reduced because they affect the compulsory heirs’ legitimes.
Determine whether insurance, retirement benefits, trust assets, or similar benefits pass under a valid beneficiary designation or special law instead of through the ordinary estate.

For example, if a house is community property, the surviving spouse may first own a share upon liquidation. Only the deceased spouse’s net share enters the hereditary estate. The exact result can change under a marriage settlement, separation-of-property regime, or rules governing property acquired before marriage.

Although succession rights are transmitted from the moment of death, that does not eliminate the need for probate, estate administration, tax clearance, registration, or partition. Where several heirs exist, the estate remains co-owned until properly divided, subject to payment of the deceased’s debts.

Who are compulsory heirs?

Under Article 887 of the Civil Code, compulsory heirs may include:

Legitimate children and descendants;
In their absence, legitimate parents and ascendants;
The surviving legal spouse;
Children born outside marriage, provided filiation is duly established; and
In circumstances defined by law, the parents of a person born outside marriage.

An adopted child is considered the legitimate child of the adopter and has reciprocal succession rights with the adopter without distinction from legitimate filiation under Sections 41–43 of the Domestic Administrative Adoption and Alternative Child Care Act. The adoption order, whether it was a stepparent adoption, and any later rescission can affect rights involving the biological family.

The Civil Code uses the term “illegitimate child.” This article uses nonmarital child where possible, while retaining the statutory term when necessary to explain the law.

What is a legitime?

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

Common configurations include the following:

Compulsory heirs who survive	Minimum shares reserved by law
Legitimate children only	Collectively, one-half of the hereditary estate, divided equally
One legitimate child and a spouse	One-half to the child; one-fourth to the spouse
Two or more legitimate children and a spouse	Children collectively receive one-half; the spouse receives a share equal to each legitimate child
Legitimate parents, with no legitimate descendants	Parents or ascendants collectively receive one-half
Legitimate parents and a spouse, with no children	One-half to the parents or ascendants; one-fourth to the spouse
Spouse alone	Generally one-half, subject to the special rule for certain marriages solemnized in articulo mortis
Nonmarital children only	Collectively, one-half
Spouse and nonmarital children only	One-third to the spouse; one-third collectively to the nonmarital children
Legitimate parents, spouse, and nonmarital children	One-half to the parents or ascendants; one-eighth to the spouse; one-fourth collectively to the nonmarital children

Each nonmarital child’s legitime is generally one-half of the legitime of a legitimate child, as provided in Article 176 of the Family Code, as amended by Republic Act No. 9255. When legitimate children, nonmarital children, and a spouse all survive, the available disposable portion, the spouse’s priority, and the statutory cap must be considered. A reliable computation therefore requires the complete family tree and estate inventory.

Whatever remains after all legitimes are satisfied is the free portion, which may generally be given by will to any legally qualified person or organization.

If there is no will: the order of intestate succession

When a person dies without a valid will, or when part of the estate is not effectively disposed of by a will, the Civil Code’s intestacy rules apply.

The following are common results:

Survivors	General intestate distribution
Legitimate children only	Equal shares
Legitimate and nonmarital children	Each nonmarital child generally receives one-half of the share of a legitimate child
Spouse and legitimate children	The spouse receives the same share as each legitimate child
Spouse, legitimate children, and nonmarital children	The spouse receives the equivalent of one legitimate child’s share; each nonmarital child generally receives one-half of that share
Spouse and nonmarital children only	One-half to the spouse; one-half collectively to the children
Spouse and legitimate parents, with no descendants	One-half to the spouse; one-half to the parents or ascendants
Legitimate parents and nonmarital children, without spouse or legitimate descendants	One-half to the parents or ascendants; one-half collectively to the nonmarital children
Spouse, legitimate parents, and nonmarital children	One-half to the parents or ascendants; one-fourth to the spouse; one-fourth collectively to the children
Spouse and siblings or children of siblings, with no descendants, ascendants, or nonmarital children	One-half to the spouse; one-half to the siblings or their qualified representatives
Spouse alone, with no competing heirs identified by law	The entire estate
No spouse, descendants, parents, or ascendants	Siblings and qualified nephews or nieces, then other collateral relatives within the fifth degree
No legally qualified private heir	The State, through escheat proceedings

Full-blood siblings ordinarily receive twice the share of half-blood siblings when they inherit together. The nearest relative generally excludes the more distant relative, except when the right of representation applies.

These are general rules. A deceased child’s descendants, competing family lines, adoption, legally established filiation, legal separation, unworthiness, and renunciation can change the calculation.

Rights of children born outside marriage

A nonmarital child can inherit from both parents, but filiation must be legally proved. Relevant evidence may include:

A civil-registry birth record;
A final judgment establishing filiation;
An admission of filiation in a public document;
A private handwritten and signed admission 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 evidence and deadline depend on the basis of the claim, the child’s and parent’s dates of birth and death, and transitional rules. A surname, family reputation, photograph, or unsupported statement may not by itself establish hereditary rights. Anyone whose filiation may be disputed should obtain advice promptly and preserve original civil records, correspondence, financial support records, and authenticated documents.

Article 992 of the Civil Code still restricts certain reciprocal intestate claims between a nonmarital child and the legitimate collateral relatives of the child’s parent. However, in Aquino v. Aquino, G.R. Nos. 208912 and 209018, 7 December 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 circumstances of birth. The ruling was expressly limited to succession by representation in the direct line; it did not generally erase Article 992 for collateral relatives or inheritance in one’s own right.

When grandchildren inherit by representation

Representation allows a qualified descendant to step into the place of the person who would have inherited.

For example, if a deceased person had two children, but one child died earlier leaving two children, the surviving child may take one branch while the two grandchildren divide the other branch. This is a division per stirpes, or by family branch—not necessarily an equal division among every individual grandchild.

Representation generally occurs in the direct descending line and, in the collateral line, only in favor of children of brothers or sisters under the conditions fixed by law. It does not occur in the ascending line.

A crucial exception is renunciation: grandchildren do not ordinarily represent an heir who simply repudiated the inheritance. By contrast, the descendants of a validly disinherited child preserve the rights of compulsory heirs over that child’s legitime under Article 923.

Rights of adopted and legitimated children

A finalized adoption gives the adoptee the status and rights of a legitimate child of the adopter. Under Republic Act No. 11642:

The adopter and adoptee have reciprocal testate and intestate succession rights without distinction from legitimate filiation.
Legal filiation extends within the adoptive family as specified by the law.
Legal ties with biological parents are generally severed, except when the biological parent is the adopter’s spouse.
Wills and the terms of the adoption or any rescission must still be examined.

A child validly legitimated through the subsequent marriage of qualified parents enjoys the same rights as a legitimate child, with the effects of legitimation generally retroacting to birth.

Informal caregiving, use of a family surname, or treating someone as an adopted child does not substitute for a lawful adoption order.

Rights of a surviving spouse—and the limits

A surviving spouse must have been in a legally valid marriage to inherit as a spouse.

Mere factual separation does not automatically end the marriage or remove succession rights. A final decree of legal separation, however, disqualifies the offending spouse from inheriting from the innocent spouse by intestacy and revokes testamentary provisions in the offending spouse’s favor by operation of law under Article 63 of the Family Code.

A live-in partner is not automatically a compulsory or intestate heir merely because the couple lived together for many years or had children. The partner may nevertheless:

Own a share of property under the co-ownership rules in Articles 147 or 148 of the Family Code;
Receive property under a valid will, but only within the disposable portion;
Receive a validly designated insurance or contractual benefit; or
Have independent claims based on ownership, contribution, contract, or reimbursement.

The partner’s ownership claim must be separated from any inheritance claim.

Can a parent leave everything to one child?

Usually not if other compulsory heirs survive.

A parent may prefer one child only to the extent allowed by the free portion. If a will or lifetime donation impairs another compulsory heir’s legitime, the prejudiced heir may seek completion of the legitime and reduction of excessive testamentary gifts or donations.

Prior donations must therefore be disclosed. A deed labelled “sale” may also be examined if the price was fictitious, grossly unsupported, or never paid, although invalidity cannot be assumed without evidence.

Disinheritance requires more than family conflict

A compulsory heir can lose the legitime through disinheritance only when:

The disinheritance is made in a valid will;
The will states a cause expressly recognized by law;
The stated cause is true; and
If denied, the other heirs can prove it.

The Civil Code lists separate causes for disinheriting descendants, parents or ascendants, and a spouse. Depending on the heir, these include specified attempts on life, certain false criminal accusations, fraud or undue influence in making a will, legally relevant refusal to provide support, maltreatment, and other enumerated grounds.

Estrangement, disapproval of a marriage, ordinary arguments, unequal affection, or a bare statement that an heir is “ungrateful” is not automatically a statutory cause. Reconciliation can also remove the right to disinherit or render an earlier disinheritance ineffective.

If the attempted disinheritance is defective, testamentary provisions are reduced insofar as necessary to restore the affected legitime.

Omission from a will is not always disinheritance

Preterition is the total omission of a compulsory heir in the direct line, without the heir being expressly disinherited or receiving anything under the will. Under Article 854, preterition may annul the institution of heirs, while legacies and devises remain valid only insofar as they do not impair protected shares.

An heir who received something may have a claim for completion of the legitime rather than preterition. The remedy therefore depends on the will’s exact wording, prior donations, and whether the omitted person is a compulsory heir in the direct line.

What makes a will legally effective?

A will does not transfer property merely because the family accepts it. Rule 75 provides that no will passes real or personal property unless it is proved and allowed by the proper court.

The two common forms are:

Notarial will: It must comply with statutory signing, attestation, witness, page, and acknowledgment requirements. Generally, it is signed by the testator and attested by at least three credible witnesses, with the testator and witnesses acknowledging it before a notary.
Holographic will: It must be entirely written, dated, and signed by the testator’s own hand. No subscribing witnesses are required, but handwriting and authenticity may have to be proved in probate.

Additional safeguards apply in circumstances such as blindness, deafness, inability to read, signing by another person, alterations, or a lost or destroyed will. A typed “last wishes” letter, an unsigned draft, a video, or a text message is not automatically a valid Philippine will.

A person holding the original will must deliver it to the proper court or named executor within 20 days after learning of the testator’s death. A named executor has a corresponding 20-day duty to present the will unless it has already reached the court.

Acceptance and renunciation of inheritance

Acceptance may be express or implied. Selling, donating, or assigning one’s hereditary right may amount to acceptance. Mere preservation or provisional administration of estate property does not necessarily do so.

Renunciation must generally be made in a public or authentic instrument or through a petition in the court handling the estate. It is not accomplished safely by an informal text message or verbal family agreement.

Acceptance or repudiation is generally irrevocable and retroacts to the moment of death, subject to limited grounds such as defective consent or discovery of an unknown will. A renunciation made “in favor of” a named person may be treated differently from a simple repudiation and can have tax consequences. Court authority is required to repudiate an inheritance for a minor or incapacitated heir.

Are heirs personally liable for the deceased’s debts?

Estate obligations must be paid before final distribution. However, an heir is generally not liable beyond the value of property received from the deceased under Article 1311 of the Civil Code.

Heirs should not distribute or sell estate property while ignoring known creditors. In a judicial settlement, the court fixes a claims period of not less than six months and not more than twelve months from the first publication of the notice to creditors. A creditor who receives such notice must act within the court-set period, subject only to the limited relief allowed by Rule 86.

Personal liability may arise from an heir’s own conduct—for example, personally assuming a debt, misappropriating estate assets, or distributing property contrary to lawful obligations.

Extrajudicial or judicial settlement?

Extrajudicial settlement

An extrajudicial settlement under Rule 74 is available when:

The deceased left no will;
The estate has no debts, subject to the Rule’s two-year presumption when no creditor petitions for administration;
All heirs agree;
All heirs are of age, or minors are represented by duly authorized legal or judicial representatives; and
All lawful heirs are included.

The heirs execute a public instrument, file it with the Register of Deeds when required, and publish notice once a week for three consecutive weeks in a newspaper of general circulation. Rule 74 also requires a bond relating to personal property. If there is only one heir, that heir may use an affidavit of self-adjudication.

Publication does not cure the omission of a lawful heir. The Rule expressly states that an extrajudicial settlement is not binding on a person who did not participate or had no notice.

Rule 74 provides a two-year procedure for certain unpaid creditors and persons deprived of participation, with special protection for specified persons under disability. That period should not be treated as an absolute bar to every possible action by an omitted, nonparticipating heir; prescription, notice, fraud, possession, registration, and the particular remedy still matter.

Judicial settlement

Court proceedings are normally required when:

There is a will that must be probated;
Heirs disagree on identity, shares, or partition;
Filiation or marriage is disputed;
The estate has unresolved debts;
An heir is missing or inadequately represented;
Property or documents are being concealed;
The validity of a sale, donation, waiver, or will is contested; or
An executor or administrator must be appointed to preserve and manage the estate.

The proper court depends on the decedent’s residence, estate value, and other jurisdictional facts.

Estate tax and transfer requirements

Estate tax is separate from the heirs’ civil-law shares. The tax is imposed on the transfer of the net taxable estate, not separately on each heir’s inheritance.

For deaths on or after 1 January 2018, the general rules under the TRAIN Law, Republic Act No. 10963, include:

A 6% estate-tax rate on the net taxable estate;
A ₱5 million standard deduction for a citizen or resident decedent;
A family-home deduction of up to ₱10 million, limited by the decedent’s interest and the regulatory conditions;
Filing of the estate-tax return within one year from death;
A possible filing extension of no more than 30 days in meritorious cases;
Payment when the return is filed; and
Payment by installment within two years from the statutory payment date when the estate lacks sufficient cash, following BIR requirements.

A filing extension should not be assumed to extend the payment deadline. Estate-tax returns with a gross estate exceeding ₱5 million require the supporting statement specified by law and certified by a CPA. A return may still be required despite no tax being due when the estate contains registered or registrable property requiring BIR clearance.

The applicable tax rate, deductions, deadline, and forms are governed by the law in force on the date of death. Estates of persons who died before 2018 may therefore follow different substantive rules.

Republic Act No. 11976 now permits estate-tax filing and payment through the electronic or manual channels authorized by law, but families should follow the BIR’s current estate-tax instructions and documentary checklist for Form 1801 and the electronic Certificate Authorizing Registration or eCAR.

The previous general estate-tax amnesty window is closed to new applicants. Families that timely availed may still be completing settlement documents, eCAR processing, or approved installments under BIR Revenue Memorandum Circular No. 33-2026. Pending bills proposing another extension are not law and should not be relied upon.

Practical steps for heirs

Secure the death certificate. Obtain certified civil-registry or PSA copies as required.
Protect the original will. Do not write on it, remove staples, laminate it, or circulate the only original.
Build a complete family tree. Include every child from every relationship, adopted or legitimated children, deceased children and their descendants, the spouse, parents, and potentially relevant siblings.
Collect civil-status evidence. Obtain birth, marriage, adoption, legitimation, legal-separation, annulment, and death records.
Inventory all assets and liabilities. Include land, buildings, bank accounts, investments, shares, vehicles, businesses, receivables, digital assets, loans, mortgages, and pending cases.
Classify property ownership. Separate the deceased’s exclusive property from community, conjugal, co-owned, or another person’s property.
Record values as of death. Obtain titles, tax declarations, bank certifications, corporate records, appraisals, and proof of outstanding loan balances.
Trace lifetime transfers. Preserve deeds of donation, purported sales, advances, waivers, and evidence of payment.
Identify the proper settlement route. Do not use an extrajudicial settlement if its legal conditions are absent.
Address the one-year tax deadline immediately. Do not wait for every family disagreement to be resolved before consulting the BIR or a tax professional.
Settle and register the estate. Complete probate or extrajudicial settlement, tax filing and payment, eCAR processing, local transfer taxes where applicable, and registration with the relevant agencies.
Maintain a transparent accounting. Anyone collecting rent, operating a business, or holding estate money should preserve records and account to the estate and co-heirs.

Evidence worth preserving

Keep originals or authenticated copies of:

Death, birth, marriage, adoption, and legitimation records;
The will, codicils, envelopes, and drafting records;
Medical records relevant to testamentary capacity;
The names and contact details of witnesses and the notary;
Titles, deeds, tax declarations, surveys, and property-tax records;
Bank, investment, stock, pension, and insurance records;
Vehicle and business registrations;
Loan agreements, mortgages, promissory notes, and creditor demands;
Receipts for funeral, preservation, tax, and administration expenses;
Lifetime donations, advances, and proof of payment for alleged sales;
Rental records, harvest proceeds, dividends, and other estate income;
Messages or recordings relevant to concealment, forgery, coercion, or undue influence; and
Copies of any affidavit of self-adjudication, extrajudicial settlement, publication, eCAR, or later title.

Preserve evidence lawfully. Do not enter private accounts without authority, alter documents, or secretly obtain protected records through misrepresentation.

Common mistakes

Dividing the gross property without first liquidating the marital regime and debts;
Treating the surviving spouse’s property share as part of the inheritance;
Excluding children born outside marriage or adopted children;
Assuming the eldest child, only son, or child who cared for the parent automatically receives more;
Treating tax declarations or tax payments as conclusive proof of ownership;
Using self-adjudication when more than one lawful heir exists;
Signing an extrajudicial settlement that omits an heir;
Assuming publication makes an invalid settlement binding on everyone;
Ignoring a will because the family prefers an informal division;
Treating an informal handwritten note as a valid holographic will without checking every requirement;
Selling a specific estate property as though one heir already owns it exclusively;
Concealing donations, withdrawals, rent, or estate income;
Signing a waiver without understanding whether it is a repudiation, donation, sale, or taxable transfer;
Waiting for a proposed tax amnesty instead of complying with current law; and
Assuming that paying estate tax alone transfers title or conclusively determines heirship.

When legal help is urgent

Consult a Philippine succession lawyer promptly when:

An original will is being withheld, altered, or threatened with destruction;
Someone is selling, mortgaging, withdrawing, or concealing estate assets;
An heir was omitted from a self-adjudication or extrajudicial settlement;
Property has already been transferred to buyers;
Filiation, adoption, marriage validity, or the identity of a spouse is contested;
A will may involve forgery, incapacity, fraud, duress, or undue influence;
A compulsory heir appears to have been disinherited or preterited;
A minor, incapacitated person, missing heir, or foreign heir is involved;
The estate includes foreign assets, land claimed by a foreign national, a corporation, or an operating business;
A court has issued a notice to creditors or set a claims deadline;
The estate-tax filing deadline is approaching or has passed;
There are large unpaid debts, tax assessments, or threatened foreclosure; or
Family members cannot agree on preservation, administration, or partition.

Qualified indigent persons may ask the Public Attorney’s Office whether assistance is available, although eligibility and the office’s authority to handle the particular dispute must be assessed.

Frequently asked questions

Do sons inherit more than daughters?

No. Legitimate children inherit without distinction based on sex, age, or whether they came from different marriages.

Does the eldest child control the estate?

No. Birth order does not create a larger hereditary share or an automatic right to administer the estate.

Can a live-in partner inherit automatically?

Generally, no. A partner who is not a legal spouse is not automatically a compulsory or intestate heir. The partner may still have a co-ownership claim or receive property through a valid will or beneficiary designation.

Can a parent completely exclude a child?

Only under narrow circumstances. A compulsory heir retains the legitime unless there is a valid statutory disinheritance, unworthiness, incapacity, or another legally recognized ground.

Do grandchildren inherit if their parent is alive?

Usually, the nearer relative excludes the more distant one. Grandchildren commonly inherit by representation when their parent predeceased or was legally incapable of inheriting. They do not ordinarily represent a living parent who simply renounces the inheritance.

Can one heir sell the family house before partition?

One heir may generally dispose of an undivided hereditary interest, but cannot unilaterally convey the other heirs’ shares or exclusive ownership of a specific estate property. The buyer may acquire only the seller’s eventual lawful interest, subject to estate settlement, debts, co-heirs’ rights, and applicable redemption rules.

Can an heir refuse an inheritance with heavy debts?

Yes, but repudiation must follow the required form and should be considered before conduct amounting to acceptance. An heir’s liability for inherited obligations is generally limited to the value received.

Is paying estate tax enough to transfer land?

No. Estate-tax compliance and eCAR issuance are only part of the process. The heirs still need a valid settlement or court order and must complete registration and other agency requirements.

Is the estate-tax amnesty still open?

Not for new applicants under the last enacted amnesty. The previous filing window closed in June 2025. Timely applicants may still have post-filing obligations under BIR guidance.
