The settlement of a decedent's estate is the legal process of identifying the properties left by a deceased person, paying off their debts and taxes, and distributing the remaining assets to the rightful heirs. In the Philippines, this process is governed primarily by the Civil Code and the Rules of Court.

The procedure varies significantly depending on whether the deceased left a will (testate) or died without one (intestate), and whether the heirs can agree among themselves.

I. Modes of Settlement

There are three primary ways to settle an estate in the Philippines:

1. Extrajudicial Settlement (Out-of-Court)

This is the most common and efficient method. It is used when the heirs are in agreement and there are no outstanding debts at the time of settlement.

Requirements:
The decedent left no will.
The decedent left no debts (or all debts have been paid).
All heirs are of legal age (or represented by judicial/legal guardians).
The settlement is made through a public instrument (Deed of Extrajudicial Settlement) filed with the Register of Deeds.
A notice of the settlement must be published in a newspaper of general circulation once a week for three consecutive weeks.
A bond must be posted if personal property is involved.

2. Judicial Settlement (Court Proceeding)

If the heirs cannot agree on the partition, or if there are complicated debts and a will, the estate must be settled through a formal court proceeding.

Testate Proceedings (Probate): If there is a will, it must be "probated." No will shall pass either real or personal property unless it is proved and allowed in the proper court. The court determines the extrinsic validity of the will (i.e., whether it followed the legal forms).
Intestate Proceedings: If there is no will, a petition for letters of administration is filed. The court appoints an Administrator to manage and distribute the estate.

3. Summary Settlement of Estates of Small Value

If the gross value of the estate does not exceed ₱10,000, the court may proceed summarily without the appointment of an executor or administrator, following a simplified process to save time and costs.

II. Successional Rights: Who Inherits?

Philippine law follows the system of Legitimes, which are portions of the estate reserved by law for "compulsory heirs." A person cannot deprive their compulsory heirs of their legitime except through a valid legal disinheritance.

Compulsory Heirs: 1. Primary: Legitimate children and descendants.

Secondary: Legitimate parents and ascendants (only in default of legitimate children).
Concurring: The surviving spouse and illegitimate children.

The Free Portion: This is the part of the estate that the deceased could have disposed of freely in a will to anyone, provided the legitimes are satisfied.

III. The Role of the Will

If a decedent left a will, they are the Testator. Under Philippine law, there are two types of valid wills:

Notarial Will: Must be in writing, signed by the testator, and attested by at least three credible witnesses in the presence of an attorney/notary public.
Holographic Will: Must be entirely written, dated, and signed by the hand of the testator himself. It does not require witnesses or notarization.

Important Note: A will cannot totally exclude a compulsory heir from their legitime unless there is a specific, legal ground for disinheritance (e.g., attempt on the life of the testator, maltreatment, or leading a dishonorable life).

IV. Mandatory Taxes: The Estate Tax

Before any property can be legally transferred to the names of the heirs, the Estate Tax must be paid to the Bureau of Internal Revenue (BIR).

Rate: Under the TRAIN Law (effective 2018), the estate tax is a flat rate of 6% of the net estate.
Deadline: The Estate Tax Return must be filed within one (1) year from the decedent's death.
Standard Deduction: A standard deduction of ₱5,000,000 is allowed for residents or citizens.
Family Home: An additional deduction of up to ₱10,000,000 may be claimed for the family home.

Failure to pay the estate tax results in penalties, surcharges, and interest, and prevents the issuance of the Certificate Authorizing Registration (CAR), which is required to transfer titles of land or shares of stock.

V. Step-by-Step General Procedure

Inventory: Identify all properties (real estate, bank accounts, vehicles, stocks) and debts.
Documentation: Secure Death Certificate, Marriage Contract (if applicable), Birth Certificates of heirs, and Titles/Tax Declarations of properties.
Appraisal: Determine the fair market value of the assets at the time of death.
Tax Filing: File the Estate Tax Return with the BIR and pay the corresponding taxes to get the CAR.
Partition:

If Extrajudicial: Sign the Deed of Extrajudicial Settlement and publish it.
If Judicial: File a petition in the Regional Trial Court (RTC).

Transfer: Present the CAR, the Deed of Settlement (or Court Order), and proof of publication/payment to the Register of Deeds or relevant government agencies to issue new titles in the names of the heirs.
