Quick answer

An heir’s share depends on four questions: Who died, what property actually belonged to that person, whether there is a valid will, and which relatives survived. Philippine law protects certain compulsory heirs through a minimum share called the legitime. A will cannot validly take that protected share away except through proper disinheritance for a cause expressly allowed by law.

If there is no valid will, the rules on intestate succession determine who inherits and in what proportion. Children, including legally adopted children, generally come first; a surviving legal spouse, illegitimate children, parents, and sometimes siblings may inherit concurrently depending on the family structure. A live-in partner, stepchild, foster child, godchild, or caregiver does not automatically inherit unless the law recognizes an ownership interest or a valid will gives that person property from the disposable portion.

Before anyone divides, sells, or transfers estate property, the family must first identify the decedent’s actual share, settle enforceable debts and taxes, account for all heirs, and follow the proper extrajudicial or court procedure.

What becomes part of the inheritance?

Successional rights arise at the moment of death, but that does not mean each heir immediately owns a particular house, lot, vehicle, or bank account. Until settlement and partition, the heirs generally hold hereditary rights in the estate as a whole.

The inheritance includes the decedent’s transmissible property, rights, and obligations. It does not include:

Property that belonged exclusively to the surviving spouse or another person;
The surviving spouse’s net share in community or conjugal property;
Rights that legally ended upon the decedent’s death; or
Property merely possessed by the decedent but owned by somebody else.

This distinction often changes the result. If a married couple’s net community property is worth ₱10 million, the surviving spouse’s own share must ordinarily be separated first. Only the decedent’s share—after the applicable property-regime rules, debts, and adjustments—is placed in the hereditary estate. The surviving spouse may then inherit an additional share from that estate.

The governing provisions are principally found in the Civil Code of the Philippines and the Family Code.

Who are compulsory heirs?

Compulsory heirs are persons whom the testator ordinarily cannot deprive of their legitime. Depending on who survives, they may include:

Legitimate children and descendants;
Legally adopted children, who have the succession rights of legitimate children;
Legitimate parents or ascendants when there are no legitimate descendants;
The surviving legal spouse;
Illegitimate children whose filiation is duly established; and
In the situations specified by law, the parents of an illegitimate decedent.

Not every compulsory heir inherits in every case. Some are excluded by a nearer class, while others inherit concurrently. For example, legitimate parents ordinarily do not receive a legitime when legitimate children survive, but the surviving spouse and illegitimate children may still concur with those children.

Sex, marital status, financial success, birth order, or who cared for the parent does not by itself change a child’s legal rank. An eldest son has no automatic preference over daughters or younger children.

Legitimate, illegitimate, and adopted children

Legitimate children

Legitimate children share equally when they inherit in their own right. Their collective legitime is generally one-half of the hereditary estate, divided equally among them. The remainder is the free or disposable portion, subject to the legitimes of other compulsory heirs who concur.

Illegitimate children

An illegitimate child is a compulsory heir of the child’s parent once filiation is properly established. Under Article 176 of the Family Code, as amended by Republic Act No. 9255, the legitime of each illegitimate child is one-half of the legitime of a legitimate child.

That “one-half” rule does not always mean the child receives exactly one-fourth of the estate. The final fraction depends on the number and classes of heirs, whether there is a will, and whether the available disposable portion is sufficient.

Filiation may be established through the civil registry record, a final judgment, an admission in a public or private handwritten instrument signed by the parent, open and continuous possession of the status of a child, or other evidence allowed by law. The proper evidence and filing deadline depend on the basis of the claim. A person relying on evidence other than the principal records or written acknowledgment may need to bring an action during the alleged parent’s lifetime. Legal advice is urgent where paternity is disputed or the alleged parent is still alive but seriously ill.

Adopted children

Under Sections 41 and 43 of Republic Act No. 11642, an adoptee is treated as the adopter’s legitimate child, and adopter and adoptee have reciprocal succession rights without distinction from legitimate filiation. The law also extends the legitimate filiation created by adoption to specified members of the adopter’s family.

Informal upbringing, use of a surname, or being treated as a child is not necessarily a legal adoption. The adoption order and applicable records should be examined.

Stepchildren, foster children, and godchildren

These relationships alone create no automatic inheritance right. Such a person may inherit if:

There was a valid legal adoption;
A valid will makes a devise or legacy within the disposable portion; or
The person independently owns part of the property through purchase, donation, co-ownership, or another lawful source.

When do grandchildren inherit?

A nearer relative generally excludes a more remote one. Therefore, a grandchild ordinarily does not inherit directly while the grandchild’s parent—the decedent’s child—is alive and qualified to inherit.

A grandchild may instead inherit by right of representation, stepping into the place of a parent who predeceased the decedent, was disinherited, or was incapable of succeeding under the circumstances recognized by law. Distribution by representation is per branch, not necessarily equal per person across the whole family.

A living heir’s simple renunciation does not ordinarily create a right of representation in that heir’s children.

The Supreme Court has ruled that a child whose parents were not married may inherit from a direct ascendant, such as a grandparent, by representing the child’s parent. Article 992’s “iron curtain” does not bar that direct-line representation. Filiation and the facts creating representation must still be proved. The ruling does not simply abolish Article 992 for all relationships; the statutory restriction remains relevant to succession between illegitimate persons and their parent’s legitimate collateral relatives. See Aquino v. Aquino, G.R. Nos. 208912 and 209018, December 7, 2021.

What does a surviving spouse inherit?

Only a person who was the decedent’s legal spouse at death inherits as a surviving spouse. The spouse’s share depends on the other heirs.

Common intestate combinations include:

Surviving heirs	General intestate division
Legitimate children and spouse	The spouse receives the same share as each legitimate child
Legitimate and illegitimate children, with spouse	The spouse is treated like one legitimate child; each illegitimate child receives half the share of a legitimate child
Illegitimate children and spouse, but no legitimate children	One-half to the spouse; one-half collectively to the illegitimate children
Legitimate parents and spouse, with no descendants	One-half to the parents or ascendants; one-half to the spouse
Legitimate parents, illegitimate children, and spouse	One-half to the parents, one-fourth collectively to the illegitimate children, and one-fourth to the spouse
Spouse and siblings or qualifying nephews and nieces, with no descendants, ascendants, or illegitimate children	One-half to the spouse; one-half to those collateral relatives
Spouse alone, with no other qualified intestate heirs	The spouse inherits the estate

These fractions apply to the net hereditary estate, not to the entire community or conjugal property before liquidation.

A spouse judicially found to have caused the legal separation is disqualified from intestate succession from the innocent spouse, and testamentary provisions in that spouse’s favor are revoked by operation of the decree. Mere physical separation, however long, is not automatically equivalent to a decree of legal separation.

Does a live-in partner inherit?

A live-in partner is not a compulsory heir or intestate heir merely because the couple lived together, had children, or jointly paid household expenses.

The partner may nevertheless have a separate ownership claim under Articles 147 or 148 of the Family Code, depending on the parties’ capacity to marry, their contributions, and how the property was acquired. That ownership share must be determined before the decedent’s estate is computed.

A valid will may also give a live-in partner property from the disposable portion, subject to compulsory heirs’ legitimes and statutory prohibitions. A document transferring property because of an illicit relationship may raise additional validity issues and should be reviewed individually.

What happens when there is a valid will?

A will controls only to the extent allowed by law. It must comply with the required formalities and must respect compulsory heirs’ legitimes.

The two usual forms are:

A notarial will, executed with the witnesses, attestation, acknowledgment, and other formalities required by the Civil Code; and
A holographic will, entirely written, dated, and signed by the testator.

A handwritten note, unsigned list, text message, video, or oral promise is not automatically a valid will.

No will passes Philippine property merely because the family accepts it. It must be proved and allowed in the proper court. Probate primarily determines whether the will was duly executed and is legally admissible. The compulsory heirs’ shares and the intrinsic validity of dispositions must also be respected during settlement.

A person who has custody of a will must deliver it to the proper court, or to the named executor, within 20 days after learning of the testator’s death. An executor named in the will has the same period after learning of the death or appointment to present the will, unless it was already filed. See Rules 75 and 76 of the Rules of Court.

Legitime, free portion, and reduction of excessive gifts

The legitime is the portion the law reserves for compulsory heirs. The testator may generally dispose only of the part left after all legitimes are satisfied.

Basic rules include:

Legitimate children collectively receive one-half of the estate as their legitime, divided equally;
In the absence of legitimate descendants, legitimate parents or ascendants generally receive one-half;
Each illegitimate child’s legitime is one-half of a legitimate child’s legitime;
The surviving spouse’s legitime varies according to the heirs with whom the spouse concurs; and
Where several classes concur, their combined legitimes can substantially reduce or exhaust the disposable portion.

Lifetime donations may also affect the computation. Certain donations are brought into account through collation, while donations exceeding the donor’s disposable portion may be reduced after death. A transfer labeled a “sale” may be questioned if it was actually gratuitous, simulated, or made for grossly inadequate consideration.

Because the arithmetic changes with every family tree, shares should be calculated only after identifying all surviving and represented heirs, prior donations, debts, and the decedent’s actual property.

What if a compulsory heir is omitted from the will?

The result depends on the nature of the omission.

Preterition is the total omission of a compulsory heir in the direct line, without the heir having received anything by will or otherwise. When the statutory requirements are met, it annuls the institution of heirs, although valid devises and legacies may remain effective if they are not excessive.

An heir who received less than the legitime is not necessarily preterited. That heir may instead demand completion of the legitime.

An heir named for less than the protected share may seek reduction of dispositions that impair the legitime. These remedies are document- and fact-sensitive; an omitted heir should not sign a quitclaim or partition before the will, donations, and estate computation are reviewed.

Can a parent disinherit a child?

Not merely because they argued, became estranged, chose a different career, married without approval, or failed to visit often.

Valid disinheritance requires:

A valid will;
Express identification of the person being disinherited;
A cause expressly recognized by the Civil Code; and
Proof of that cause if the disinherited heir contests it.

The statutory grounds differ for descendants, parents or ascendants, and spouses. They include specified serious conduct, not a general power to punish family members. If no legal cause is stated, or the stated cause is not proved, the disinheritance is ineffective to the extent that it prejudices the heir’s legitime. Reconciliation may also erase the effect of disinheritance in circumstances covered by law.

Separate rules on incapacity or unworthiness may disqualify an heir for grave acts such as intentionally causing the decedent’s death. A family accusation alone is not enough; the precise statutory ground and required proof matter.

Who inherits when there is no will?

Intestate succession applies when there is no will, the will is void or has lost validity, the will does not dispose of the entire estate, or an instituted heir cannot or will not inherit and no effective substitute or accretion applies.

The general priority is:

Children and other descendants;
Parents and other ascendants, if there are no descendants entitled to inherit;
Illegitimate children and their descendants under the rules governing their rights;
The surviving spouse, who may concur with descendants, ascendants, illegitimate children, or certain collateral relatives;
Brothers and sisters, qualifying nephews and nieces, and more remote collateral relatives within the fifth civil degree; and
The State, if no qualified heir exists.

This is not a simple one-person-at-a-time list because the spouse and illegitimate children may inherit concurrently with other classes.

Among collateral relatives, full-blood and half-blood relationships may produce different shares. Representation in the collateral line is limited, principally benefiting children of brothers or sisters when they concur with surviving siblings in the circumstances provided by law.

Simple intestate examples

Assume the net hereditary estate is ₱6 million, with no will and no unresolved debt:

Two legitimate children and a surviving spouse receive ₱2 million each.
One legitimate child, two illegitimate children, and a surviving spouse divide by a 2:1:1:2 ratio: ₱2 million to the legitimate child, ₱1 million to each illegitimate child, and ₱2 million to the spouse.
A surviving spouse and three illegitimate children, with no legitimate descendants or ascendants, divide the estate one-half to the spouse and one-half collectively to the children: ₱3 million to the spouse and ₱1 million to each child.

These illustrations change if representation, prior donations, disputed filiation, a marriage-property issue, or a valid will is involved.

Debts come before distribution

Heirs inherit only what remains after enforceable estate obligations, administration expenses, taxes, and other lawful charges are settled in the proper order.

An heir is generally not personally liable for the decedent’s contractual obligations beyond the value of property received from the estate. An heir who distributes, conceals, or disposes of estate assets prematurely, however, may create personal exposure or complicate recovery by creditors and co-heirs.

In a judicial estate proceeding, the court’s notice to creditors sets a claims period of not less than six months and not more than 12 months from the first publication. Certain claims must be filed within that period or risk being barred, subject to the Rules’ limited exceptions. A creditor who learns of an estate case should act immediately rather than rely on an ordinary contractual deadline.

Extrajudicial settlement or court settlement?

Extrajudicial settlement

Under Rule 74, heirs may settle without administration proceedings when:

The decedent left no will;
The estate has no outstanding debts;
All heirs participate;
All heirs are of age, or minors or incapacitated heirs are represented by legally authorized representatives;
The settlement is placed in a public instrument, or a sole heir executes an affidavit of self-adjudication;
The required bond or lien protections are observed; and
The fact of settlement or adjudication is published once a week for three consecutive weeks in a newspaper of general circulation.

The deed must be filed and used for the appropriate registration and tax processes. Publication is not permission to omit a known heir. A settlement executed without an heir’s knowledge or participation may not bind that heir merely because it was published.

Rule 74 also contains a two-year protection period for certain heirs and creditors after settlement and distribution. That period is not a universal rule that permanently validates a fraudulent deed or extinguishes every omitted heir’s claim. Notice, participation, fraud, repudiation of co-ownership, registration, and the remedy pursued can produce different prescriptive periods.

Judicial settlement

Court proceedings are generally necessary or safer when:

There is a will;
Heirs disagree about identity, shares, partition, or administration;
An heir is missing or improperly represented;
Filiation or adoption is disputed;
The estate has substantial or contested debts;
Property ownership is disputed;
A creditor or heir needs court protection;
An administrator must collect, preserve, or sell assets; or
Extrajudicial settlement requirements cannot be met.

Venue is generally based on the decedent’s residence or domicile at death. For a nonresident decedent, the proceeding may be filed where the decedent had property in the Philippines. Court level depends on gross estate value: under Republic Act No. 11576, first-level courts have probate jurisdiction where the estate does not exceed ₱2 million, while the Regional Trial Court has jurisdiction when it exceeds ₱2 million.

Estate tax and transfer requirements

Inheritance shares and estate tax are different questions. A person may be a legal heir even if the estate has not yet completed tax clearance, but registrable property ordinarily cannot be transferred without the required BIR authority.

For a decedent who died on or after January 1, 2018:

Estate tax is generally 6% of the net taxable estate;
A citizen or resident’s estate has a ₱5 million standard deduction;
The family-home deduction is allowed up to ₱10 million, subject to the statutory conditions;
The surviving spouse’s net share in community or conjugal property is excluded from the decedent’s taxable estate after the proper computation;
BIR Form No. 1801 must generally be filed within one year from death;
Payment is generally due when the return is filed;
A return is required where registrable property needs a Certificate Authorizing Registration, regardless of gross estate value; and
A CPA-certified statement is required when the gross estate exceeds ₱5 million.

A meritorious request may support an extension of up to 30 days to file. Where immediate payment would cause undue hardship, the BIR may allow a payment extension of up to five years for judicial settlement or two years for extrajudicial settlement. Approved cash installments must generally be completed within two years from filing. These are not automatic; a timely request and BIR approval are required.

The applicable tax rate and deductions are ordinarily those in force on the date of death. Older estates should not automatically apply the current 6% regime. The extended estate-tax amnesty expired on June 14, 2025; as of the source-check date below, it is no longer open absent a new law.

Current forms, requirements, and payment guidance are available from the BIR estate-tax page, BIR Form No. 1801, and Revenue Regulations No. 12-2018.

Practical steps for heirs

Secure the death certificate. Obtain the civil-registry or PSA records needed for settlement and tax filing.
Build a complete family tree. List the legal spouse, all children, adopted children, possible illegitimate children, predeceased children and their descendants, parents, and other relatives who may inherit.
Collect proof of relationship. Preserve birth, marriage, death, adoption, legitimation, recognition, and court records. Resolve inconsistent names or civil-registry entries early.
Locate and protect the original will. Do not write on it, remove pages, staple new documents to it, or treat a photocopy as the original.
Inventory assets and liabilities. Include land, condominium units, vehicles, bank deposits, investments, business interests, receivables, digital assets, loans, mortgages, unpaid taxes, and pending cases.
Determine actual ownership. Review titles, deeds, marriage settlements, dates of acquisition, source of funds, and the applicable community, conjugal, separation-of-property, or co-ownership rules.
Check prior donations and advances. Obtain deeds, transfer records, and evidence of value. A donation may affect collation, legitimes, and tax computations.
Preserve the estate. Secure property, maintain insurance where possible, document rental income and expenses, and avoid unilateral withdrawals, sales, or title transfers.
Choose the correct settlement process. Do not use a deed of extrajudicial settlement when there is a will, an unpaid debt, an omitted heir, or a genuine dispute requiring judicial determination.
Meet the tax deadline. Register the estate as required, prepare Form 1801, request an extension before the deadline if justified, pay through an authorized channel, and obtain the appropriate electronic Certificate Authorizing Registration.
Partition only after the net estate and shares are known. A partition may assign specific assets rather than cash, but the agreed values and any equalization payments should be clear.
Complete each transfer. Land, shares, vehicles, bank deposits, and business interests have different registration or release requirements. Verify the current checklist with the relevant BIR office, Registry of Deeds, bank, corporation, or agency.

Evidence worth preserving

Keep original or certified copies of:

Death, birth, marriage, adoption, and legitimation records;
The original will and any codicil;
Land titles, tax declarations, deeds, and condominium certificates;
Bank, securities, pension, insurance, and loan records;
Corporate records and proof of business ownership;
Marriage settlements and records showing when and how property was acquired;
Deeds of donation and proof of prior advances;
Receipts for administration, preservation, funeral, and tax expenses;
Written acknowledgment of filiation and relevant correspondence;
Photographs and inventories of movable property;
Rental contracts, income records, and expense ledgers;
Notices, court papers, publications, and proof of service; and
Signed deeds, waivers, powers of attorney, tax returns, payment confirmations, and eCARs.

Use copies for routine circulation and keep originals secure. Record who takes possession of original titles, wills, and negotiable documents.

Common mistakes that cause inheritance disputes

Dividing the couple’s entire property as though all of it belonged to the decedent;
Treating the family home as the automatic property of the child who lives there;
Excluding an illegitimate or adopted child;
Assuming grandchildren always inherit alongside their living parent;
Believing the eldest child controls the estate;
Treating a live-in partner as a legal spouse without checking ownership rights;
Ignoring a will because all relatives initially agree;
Publishing an extrajudicial settlement while deliberately omitting an heir;
Letting one heir sell or mortgage an entire estate property without authority;
Signing a blank deed, broad quitclaim, or unexplained “waiver”;
Assuming a waiver made before the decedent’s death is an effective renunciation of future inheritance;
Distributing property before debts and estate tax are addressed;
Missing the one-year estate-tax deadline;
Failing to respond to a court’s creditor notice;
Delaying a disputed filiation claim until crucial witnesses or the alleged parent have died; and
Relying on an old tax-amnesty checklist after the amnesty has expired.

When legal help is urgent

Consult a Philippine succession lawyer promptly if:

Someone is hiding, destroying, or altering a will;
An estate asset is being sold, mortgaged, withdrawn, or transferred without consent;
A deed excludes a known heir;
Filiation, adoption, marriage validity, or citizenship is disputed;
A court notice or creditor deadline has been received;
The one-year estate-tax deadline is approaching or has passed;
There are minor, incapacitated, missing, or overseas heirs;
The estate includes a corporation, family business, foreign property, or foreign heirs;
A spouse or partner claims ownership outside the estate;
There are conflicting deeds, simulated sales, or substantial lifetime donations;
The decedent was a Muslim governed by the Code of Muslim Personal Laws;
A beneficiary may be disqualified or unworthy; or
An heir is being pressured to sign a waiver or partition without an inventory and computation.

Qualified indigent clients may inquire with the Public Attorney’s Office about eligibility for assistance.

Special cases

Muslim estates

The Civil Code rules discussed above are not a substitute for the special succession provisions applicable to deceased Muslims. Book Three of Presidential Decree No. 1083, the Code of Muslim Personal Laws, provides distinct rules on heirs, fixed shares, wills, administration, and Shari’a court jurisdiction.

Foreign decedents, heirs, or property

Under Article 16 of the Civil Code, the decedent’s national law generally governs the order of succession, the amount of successional rights, and the intrinsic validity of testamentary provisions, regardless of where the property is located. Philippine procedural, tax, registration, land-ownership, and public-policy rules may still apply to Philippine assets.

Foreign law must ordinarily be properly alleged and proved in court. A foreign heir’s acquisition of Philippine land also requires constitutional analysis; the hereditary-succession exception should not be assumed to validate every testamentary transfer.

Frequently asked questions

Can a married daughter inherit equally with her brothers?

Yes. Sex, surname, marriage, and birth order do not reduce a legitimate child’s share.

Does the child who cared for the parent receive more?

Not automatically. The parent may reward the caregiver through a valid will within the disposable portion, a valid lifetime transaction, or compensation supported by an enforceable agreement. Caregiving alone does not enlarge the statutory share.

Can an illegitimate child inherit from the father?

Yes, if filiation is duly established. The child is a compulsory heir of the father, but generally has a legitime equal to one-half of a legitimate child’s legitime.

Can an illegitimate grandchild inherit from a legitimate grandparent?

Yes, by right of representation in the direct line when the legal requirements are present. The grandchild must prove filiation and the basis for representing the parent.

Can siblings inherit if the decedent had a spouse?

They may. If there are no descendants, ascendants, or illegitimate children, qualifying siblings, nephews, or nieces may share one-half of the intestate estate with the surviving spouse. A valid will may ordinarily exclude siblings because they are not compulsory heirs.

Can an heir sell inherited land before partition?

An heir may have the ability to transfer an undivided hereditary interest, but cannot unilaterally convey the entire property or another heir’s share. Any buyer takes significant risks from debts, probate, tax requirements, co-ownership, and later partition.

Can an heir refuse the inheritance?

Yes, after the decedent’s death and once the heir knows of the right to inherit. Repudiation must follow the required formal form and is generally irrevocable. A renunciation specifically favoring selected heirs may also have donor’s-tax consequences, unlike a proper general renunciation.

Are heirs personally liable for the decedent’s loans?

Generally, liability does not exceed the value of inherited property. Creditors should be paid from the estate before distribution, and heirs who have already received property may be required to return value needed for lawful claims.

Is a notarized extrajudicial settlement enough to transfer land?

No. The deed must satisfy Rule 74, include all heirs, undergo the required publication, comply with BIR requirements, obtain the appropriate eCAR, and be registered with the Registry of Deeds. Local transfer requirements may also apply.

Does inheritance prescribe?

There is no single deadline for every inheritance dispute. Estate-tax, creditor, filiation, fraud, reconveyance, probate, and co-ownership issues have different rules. An heir who learns of exclusion, a hostile claim, or a questionable deed should act immediately rather than assume the right can be enforced indefinitely.
