Quick answer

In the Philippines, a person’s heirs do not simply divide every asset equally. The lawful shares depend on:

whether the deceased left a valid will;
the deceased’s family relationships and marital status;
whether children are marital, nonmarital, legitimated, or legally adopted;
whether an heir predeceased, renounced, or is legally disqualified;
which assets actually belonged to the deceased; and
the estate’s debts, taxes, expenses, and prior donations.

Certain close relatives are compulsory heirs whose minimum shares—called legitimes—generally cannot be taken away by a will. If there is no valid will, the rules on intestate succession determine who inherits and in what proportions.

No heir should sell, mortgage, partition, or claim exclusive ownership of estate property merely because the person is a child, spouse, or named beneficiary. The estate must first be identified and properly settled.

Inheritance begins at death, but the estate must still be settled

Successional rights are transmitted from the moment of death. This does not mean that each heir immediately owns a particular room, parcel, vehicle, or bank account. Until the estate is partitioned, the heirs generally hold hereditary rights over the estate as a whole, subject to administration, valid debts, taxes, and the rights of other heirs.

The estate may include only the deceased’s own property and share in jointly or matrimonially owned property. For example, where property belongs to the spouses’ absolute community or conjugal partnership, the marital property regime must first be liquidated. The surviving spouse’s own share is separated before the deceased’s net estate is distributed.

The basic sequence is:

Identify the deceased’s property and ownership interests.
Separate property belonging to the surviving spouse or other co-owners.
Account for enforceable debts, estate expenses, taxes, and relevant lifetime donations.
Determine the valid will, if any.
Identify every lawful heir and establish the required relationships.
Compute the legitimes and disposable portion.
Settle and partition the net estate through the proper procedure.
Transfer and register the assets in accordance with tax and registration requirements.

Who are compulsory heirs?

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

legitimate children and descendants, with children ordinarily excluding more remote descendants except where representation applies;
in the absence of legitimate descendants, legitimate parents and ascendants;
the surviving legal spouse; and
nonmarital children whose filiation is legally established.

The exact combination matters. A parent ordinarily does not receive a legitime when the deceased left legitimate children or descendants. Brothers, sisters, nephews, nieces, and more remote relatives are not compulsory heirs merely because they are family members, although they may inherit under intestate succession when closer heirs are absent.

A partner who was never legally married to the deceased is not a surviving spouse for succession purposes. Cohabitation alone does not create the inheritance rights of a legal spouse, although the partner may have separate ownership or reimbursement claims supported by the facts and applicable property law.

What is a legitime?

A legitime is the part of the estate reserved by law for a compulsory heir. A testator may distribute only the portion that remains freely disposable after all legitimes are protected.

Common starting rules include:

Legitimate children collectively receive one-half of the hereditary estate as their legitime, divided among them.
A nonmarital child’s legitime is generally one-half of the legitime of a legitimate child.
In the absence of legitimate descendants, legitimate parents or ascendants generally receive one-half.
A surviving spouse’s legitime changes depending on whether the spouse concurs with legitimate children, nonmarital children, parents, or no other compulsory heir.

These fractions should not be applied in isolation. The Civil Code contains special rules for combinations of heirs, including a surviving spouse with one legitimate child, several legitimate children, legitimate ascendants, or nonmarital children. The available estate and the disposable portion can also limit the total allocation.

A reliable computation therefore requires a complete family tree, the marriage and filiation records, the will, a property inventory, the marital property regime, liabilities, and potentially reducible lifetime donations.

Can a will exclude a child, spouse, or parent?

Not ordinarily if that person is a compulsory heir entitled to a legitime.

A will may assign the disposable portion to another person, but it cannot simply erase a compulsory heir’s legitime. Article 904 of the Civil Code protects the legitime against deprivation or burdens except in cases expressly permitted by law.

A compulsory heir may be deprived of the legitime only through a legally effective disinheritance. This requires:

a valid will;
an express identification of the legal cause;
a cause specifically recognized by the Civil Code; and
proof of that cause if the disinherited heir denies it.

Family conflict, disappointment, estrangement, or a parent’s personal preference is not automatically a lawful cause. The statutory grounds differ depending on whether the person being disinherited is a child or descendant, parent or ascendant, or spouse.

If disinheritance lacks a lawful cause, states a cause that cannot be proved, or fails to follow the required form, it may be ineffective to the extent necessary to restore the heir’s legitime.

What happens when a compulsory heir is omitted from a will?

The answer depends on whether the omission amounts to preterition under Article 854 of the Civil Code.

Preterition generally involves the total omission of a compulsory heir in the direct line—without that heir receiving anything by will or as an advance—from the inheritance. When its requirements are met, it can annul the institution of heirs, although valid devises and legacies may remain effective insofar as they are not inofficious.

Preterition is different from merely giving an heir less than the legitime. If an heir received something but not enough, the usual remedy may be completion of the legitime rather than annulment of the institution of heirs.

Because small factual differences change the remedy, an omitted heir should have the entire will and donation history reviewed before signing a waiver or settlement.

Who inherits when there is no valid will?

Intestate succession applies when there is no will, the will is void or ineffective, the will does not dispose of the whole estate, or an instituted heir cannot inherit and no valid substitute or other applicable rule covers the share.

The Civil Code generally gives priority to the closest degree within the appropriate line, subject to the rights of representation and the surviving spouse. Depending on who survives, intestate heirs may include:

children and descendants;
parents and ascendants when there are no descendants;
the surviving legal spouse;
nonmarital children and their descendants under the governing rules;
brothers, sisters, nephews, and nieces;
other collateral relatives within the degree allowed by law; and
the State when no qualified heir exists.

This is not a simple waiting list. Some heirs inherit concurrently. A surviving spouse, for example, may inherit together with children or parents. Half-blood and full-blood siblings may receive different shares. Representation may allow descendants to take the place of a person who predeceased or was incapacitated to inherit.

Rights of marital and nonmarital children

A marital child may inherit from either parent, subject to the ordinary rules on succession.

A nonmarital child may inherit from the child’s parent if filiation is legally established. The child’s legitime is generally one-half of the legitime of a legitimate child, although the final amount depends on the other heirs and the estate.

Article 992 still contains a restriction on reciprocal intestate succession between nonmarital children and the marital children or relatives of their parents. However, it must be read in light of the Supreme Court’s en banc ruling in Aquino v. Aquino, G.R. Nos. 208912 and 209018. The Court held that a nonmarital grandchild may represent a deceased parent in inheriting from a grandparent under Article 982, regardless of birth status, provided the required filiation and right of representation are established. The ruling was limited to representation in the direct descending line and did not broadly resolve inheritance in one’s own right from collateral relatives.

Because Article 992 questions remain fact-sensitive, claims involving grandparents, siblings, uncles, aunts, nephews, nieces, or mixed marital and nonmarital lines require careful legal analysis.

Filiation must be established

Biological relationship may need to be proved in the manner required by the Family Code and jurisprudence. Depending on the circumstances, relevant evidence may include:

an authenticated civil-registry birth record;
a final judgment establishing filiation;
a record of admission in a public document or a private handwritten instrument signed by the parent;
proof of open and continuous possession of the status of a child;
other evidence permitted by the Rules of Court and applicable jurisprudence; and
properly ordered and evaluated DNA evidence where legally appropriate.

A surname, family reputation, photograph, social-media post, or informal acknowledgment may not by itself resolve the legal issue. Time limits for an action concerning filiation can also depend on the evidence relied upon and whether the alleged parent is alive.

Rights of adopted children

A legally adopted child generally acquires the rights of a child of the adopter, including succession rights under the applicable adoption law. The precise effects on relationships with biological parents depend on the governing statute, the adoption order, whether the adopter is the spouse of a biological parent, and whether an adoption has been validly rescinded.

The current framework includes the Domestic Administrative Adoption and Alternative Child Care Act, Republic Act No. 11642. Informal caregiving, use of the family surname, or treatment as a child does not by itself equal a completed legal adoption.

When can grandchildren inherit?

Grandchildren may inherit:

in their own right when the succession rules directly call them;
by representation when they legally take the place of a parent who predeceased or was incapacitated to inherit; or
under a valid will, subject to the legitimes of compulsory heirs.

Representation generally operates in the direct descending line, not the ascending line. Division by representation is per stirpes: the representatives collectively receive the share that the represented person would have received.

Representation does not automatically apply whenever a parent receives nothing. In particular, heirs who repudiate their inheritance generally cannot be represented merely because of that repudiation.

Can an heir refuse or waive an inheritance?

An heir may accept or repudiate an inheritance, but the decision has serious consequences.

Acceptance may be express or may arise from acts that necessarily imply an intention to accept. Repudiation must comply with Article 1051 of the Civil Code: it must be made in a public or authentic instrument, or by petition presented to the court handling the estate.

Acceptance or repudiation generally cannot be partial, conditional, or for a limited period. An heir should not sign a deed described casually as a “waiver” without checking whether it is actually:

a repudiation before acceptance;
a transfer of an already inherited share;
a donation to another heir;
a sale;
part of a partition; or
a transaction with separate tax consequences.

An heir ordinarily cannot renounce an inheritance before the person has died because no hereditary right has yet vested.

Can an heir sell inherited property before partition?

An heir may, in some circumstances, transfer the hereditary right or undivided interest that the heir actually owns. But one heir cannot validly sell the entire estate or a specific property as sole owner when other heirs have rights in it.

Before partition, a buyer may acquire only the seller-heir’s hereditary interest, subject to the final settlement, the rights of co-heirs and creditors, taxes, and possible redemption rights. A deed signed by only one heir does not automatically bind omitted heirs.

For land, check the title, annotations, tax declaration, marital property history, pending cases, occupants, and every settlement document before paying or signing.

How an estate may be settled

Extrajudicial settlement

Under Section 1, Rule 74 of the Rules of Court on special proceedings, heirs may generally settle an estate without appointing an administrator when:

the deceased left no will;
the estate has no outstanding debts;
all heirs participate;
all heirs are of age, or minors are represented by duly authorized judicial or legal representatives; and
the required public instrument, filing, publication, and bond requirements are satisfied.

A sole heir may use an affidavit of self-adjudication when legally proper.

Publication does not cure the omission of an heir. Rule 74 expressly states that an extrajudicial settlement does not bind a person who did not participate or had no notice.

The Rules presume that the deceased left no debts if no creditor petitions for letters of administration within two years from death. That presumption is not permission to disregard a known debt.

Judicial settlement

Court proceedings are usually necessary or prudent when:

there is a will that must be probated;
the validity or interpretation of a will is disputed;
heirs disagree;
an heir, creditor, or property has been omitted;
there are unresolved debts;
filiation, marriage, ownership, capacity, or disinheritance is contested;
minors or incapacitated persons are not adequately represented;
an administrator is needed to preserve or recover property; or
the estate cannot be safely distributed extrajudicially.

A will cannot pass property unless it is allowed in probate. Even a document that relatives accept privately may still require judicial probate before it can operate as a will.

Deadlines and the two-year Rule 74 period

Rule 74 provides a two-year remedy concerning certain claims after a summary or extrajudicial distribution, including claims of an heir who was unduly deprived of lawful participation. The bond and estate property may also remain answerable during the rule’s two-year period.

However, the two-year rule must not be treated as an absolute deadline for every omitted-heir or ownership claim. Supreme Court decisions distinguish between participants or persons with notice and heirs who never participated and had no notice. Fraud, trust, possession, registration, and the nature of the remedy may affect prescription or laches.

The Supreme Court discussed these distinctions in Treyes v. Antonio, G.R. No. 232579. Anyone omitted from a settlement should act immediately rather than assume that a longer period will apply.

Estate tax and transfer requirements

Estate tax is separate from the heirs’ civil-law shares. For deaths covered by the current TRAIN-law regime, the estate tax is generally six percent of the net taxable estate, subject to deductions and the rules applicable on the date of death.

The estate tax return is generally due within one year from death. Extensions, installment arrangements, partial dispositions, filing channels, documentary requirements, and penalties depend on the Tax Code and current BIR issuances. The official starting point is the BIR’s Estate Tax page.

Tax compliance does not determine who the lawful heirs are. Likewise, paying real-property tax, possessing a title, or obtaining a tax clearance does not by itself cure an invalid partition or extinguish another heir’s rights.

Evidence heirs should preserve

Secure originals or certified copies where available:

death certificate;
birth, marriage, adoption, annulment, and death records relevant to the family tree;
the original will, codicils, and envelopes or custody records;
land titles, tax declarations, deeds, surveys, and condominium documents;
bank, investment, insurance, pension, business, and loan records;
vehicle registrations and valuable-property records;
documents proving the deceased’s ownership or co-ownership;
prenuptial agreements and records showing the marital property regime;
receipts and evidence of funeral, medical, preservation, and estate expenses;
loan documents and creditor communications;
deeds of donation and records of advances to heirs;
prior extrajudicial settlements, affidavits, waivers, and court orders;
evidence of filiation or acknowledgment; and
messages or records showing concealment, threats, unauthorized sales, or removal of estate property.

Make a dated inventory. Preserve electronic records in their original form and keep backups. Do not alter documents or obtain private account data unlawfully.

Practical steps for an heir

Obtain the death certificate and civil-registry documents needed to build a complete family tree.
Locate the original will, if one may exist. Do not destroy, conceal, annotate, or privately revise it.
Secure property without excluding lawful co-heirs or taking assets for personal use.
List all assets, co-owners, debts, donations, and possible claimants.
Determine the deceased’s marital status and property regime.
Notify the other known heirs and avoid secret settlements.
Ask the BIR, Register of Deeds, banks, and other institutions for their current documentary requirements.
Have the heirs and shares reviewed before executing a deed.
Use judicial settlement when the requirements for extrajudicial settlement are not genuinely met.
Record every distribution and obtain properly drafted receipts, releases, and transfer documents.

Common mistakes

Assuming the eldest child controls the estate.
Dividing gross assets without first liquidating marital property and paying valid obligations.
Treating every relative as a compulsory heir.
Assuming all children always receive identical shares.
Excluding a nonmarital or adopted child without reviewing filiation and adoption records.
Believing publication makes an omitted-heir settlement valid.
Using an affidavit of self-adjudication despite the existence of other heirs.
Selling a specific estate property as though one heir owns it exclusively.
Relying only on a tax declaration instead of checking ownership documents.
Signing a waiver without understanding whether it is a repudiation, donation, sale, or partition.
Ignoring prior donations that may affect legitimes and collation.
Waiting for the Rule 74 period or a tax deadline to expire before obtaining advice.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

someone is concealing or destroying a will;
estate money is being withdrawn or land is being sold without authority;
an heir was omitted from a deed or court case;
signatures or civil-registry records may be falsified;
a nonmarital child’s filiation is disputed;
a minor or incapacitated heir is involved;
the deceased had multiple marriages, a void marriage, or an unresolved marital case;
property is held through a corporation, partnership, trust arrangement, nominee, or overseas account;
an heir is being pressured to sign a waiver;
the BIR deadline is approaching;
a title has already been transferred to another person; or
the estate has substantial debts or competing creditors.

Urgent court relief may be necessary to preserve property, prevent an unauthorized transfer, appoint an administrator, recover estate assets, or protect an omitted heir.

Frequently asked questions

Does the eldest child receive a larger share?

No. Birth order does not ordinarily increase an heir’s lawful share or give automatic authority to administer the estate.

Can parents give everything to only one child in a will?

Only the disposable portion may generally be given freely. The other compulsory heirs’ legitimes must still be protected unless a valid statutory disinheritance applies.

Does a married daughter inherit less than a son?

No. Sex and marital status do not reduce a child’s hereditary share.

Does a nonmarital child inherit?

Yes, from the child’s parent when filiation is legally established, but the applicable share and rights involving other relatives depend on the Civil Code and current jurisprudence.

Can a live-in partner inherit automatically?

Not as a surviving spouse merely because of cohabitation. The partner may inherit under a valid will from the disposable portion or may have independent property claims, depending on the facts.

Do grandchildren always inherit when their parent has died?

Not automatically. They may inherit by representation when its legal requirements are met. Their collective share is generally limited to what the represented parent would have received.

Can siblings inherit if the deceased had children?

Ordinarily, children and qualifying descendants exclude siblings from intestate succession. A sibling may still receive property under a valid will from the disposable portion.

Is a handwritten will valid?

A holographic will may be valid if it complies with the Civil Code’s requirements, including that it be entirely written, dated, and signed by the testator. It must still be probated.

Can heirs settle without going to court?

Yes, but only when the requirements for an extrajudicial settlement or self-adjudication are satisfied. A will, disagreement, debt, missing heir, or disputed status may require judicial proceedings.

Does paying estate tax make someone the owner?

No. Tax payment is required for transfer but does not replace a valid determination of heirs, settlement, partition, and registration.
