Intestate succession occurs when a person dies without leaving a valid will or when the will does not dispose of all of his or her properties. In such cases, the law steps in to determine how the estate shall be distributed among the legal heirs. The rules on intestate succession in the Philippines are primarily found in the Civil Code of the Philippines (Republic Act No. 386), particularly Articles 960 to 1014.

General Principles

Succession is the transmission of the rights and properties of a deceased person to his or her heirs. Intestate succession applies by operation of law in the absence of testamentary dispositions. The hereditary estate consists of all properties owned by the decedent at the time of death, after deducting debts, funeral expenses, and other charges.

The net estate is then distributed to the heirs according to the order established by law. Heirs in intestate succession include descendants, ascendants, the surviving spouse, illegitimate children, and collateral relatives, in that order of priority, with certain rules of concurrence.

Order of Intestate Heirs and Concurrence

The primary heirs are the legitimate children and descendants of the deceased. In their absence, the legitimate parents and ascendants succeed. The surviving spouse concurs with these classes of heirs under specific sharing rules.

When the decedent is survived by legitimate parents or ascendants and a surviving spouse, but no children or descendants (whether legitimate or illegitimate), the surviving spouse and the ascendants inherit together.

Article 997 of the Civil Code explicitly provides: “When the widow or widower survives with legitimate parents or ascendants of the deceased, the former shall be entitled to one-half of the hereditary estate, and the latter to the other half.”

This means the surviving spouse receives fifty percent (50%) of the net hereditary estate. The remaining fifty percent (50%) goes to the legitimate ascendants of the deceased.

Division Among Ascendants (Parents)

The term “ascendants” refers to the ancestors in the direct line, with parents being the closest. If both the father and mother of the deceased are alive, they share the ascendants’ portion equally. Each parent thus receives one-fourth (25%) of the hereditary estate.

If only one parent survives, that sole surviving parent is entitled to the entire fifty percent (50%) share allocated to the ascendants.

Should both parents be deceased, the grandparents or other nearer ascendants in the respective paternal and maternal lines may inherit the ascendants’ share. The division among ascendants follows the rule of proximity in degree: nearer ascendants exclude the more remote ones. In the same degree, they divide per capita within their line.

Note that ascendants inherit only in the absence of descendants. The presence of any child or descendant, legitimate or illegitimate, excludes the ascendants from the succession, though the spouse would then concur with the children.

Property Regimes and the Hereditary Estate

A critical aspect in determining shares is the property regime of the marriage. Philippine law recognizes different regimes under the Family Code:

Conjugal Partnership of Gains (default for marriages before August 3, 1988)
Absolute Community of Property (default for marriages on or after August 3, 1988)

Upon the death of a spouse:

The surviving spouse is entitled to one-half of the community or conjugal property as his or her share, which is not part of the estate.
The other half of the community/conjugal property, plus any exclusive or separate properties of the deceased (such as properties brought into the marriage or acquired by inheritance or gratuitously), constitutes the hereditary estate.

The shares under Article 997 are applied only to this hereditary estate.

Practical Illustration

Assume the deceased and surviving spouse acquired conjugal properties valued at P2,000,000, and the deceased had P400,000 in exclusive properties. No debts.

Surviving spouse’s automatic share: P1,000,000 (half of conjugal).
Hereditary estate: P1,000,000 (deceased’s conjugal share) + P400,000 = P1,400,000.

Distribution:

Surviving spouse inherits 1/2 of P1,400,000 = P700,000.
Total for spouse: P1,000,000 + P700,000 = P1,700,000.
Parents/ascendants: P700,000 (divided equally if both alive).

This results in the surviving spouse often receiving a larger portion of the total assets when community properties are involved.

Additional Legal Considerations

Legitime Protection: The shares in intestate succession align with legitimes. Ascendants have a legitime of one-half of the estate when they concur with the spouse.
Requirements for the Surviving Spouse: The spouse must have been validly married to the decedent and not legally separated in a manner that forfeits rights. Void or annulled marriages do not confer inheritance rights.
Unworthy Heirs: Under Articles 1027 to 1029 of the Civil Code, heirs who committed certain acts against the decedent (e.g., conviction for attempting to kill the decedent, false accusation, or adultery in certain cases) are disqualified.
Renunciation and Accrual: An heir may renounce the inheritance, causing the share to accrue to the co-heirs in proportion to their shares.
No Representation in Ascending Line Generally: Unlike in the descending line, representation is limited in the ascending line; the nearer degree excludes the farther.
Presence of Other Heirs: Illegitimate children would concur and alter shares, typically receiving half the share of legitimate heirs in some contexts, but their presence would exclude ascendants. Collaterals (siblings) only inherit if there are no descendants, ascendants, or spouse.
Administration and Partition: The estate must first settle obligations. Heirs may partition amicably or through court if necessary. Actions for partition prescribe after 10 years from the right of action accrues.
Taxes and Expenses: Estate taxes, funeral expenses, and debts are deducted prior to distribution.
Special Cases: For Muslim Filipinos, the Code of Muslim Personal Laws (PD 1083) may apply different rules. Adopted children are treated as legitimate for succession purposes.

These rules ensure equitable distribution balancing the rights of the surviving spouse, who shared life with the decedent, and the parents who gave life to the decedent.

The distribution promotes family harmony while respecting blood relations in the ascending line when no direct descendants exist.

This framework has remained consistent since the Civil Code’s enactment, with property relations updated by the Family Code.
