Can you disinherit an heir under Philippine law? The short answer is yes—but only under very limited circumstances prescribed by law. Philippine law strongly protects compulsory heirs by reserving for them a portion of the estate known as the legitime. A parent, spouse, or other testator cannot simply remove a compulsory heir from inheritance because of personal disagreements, family conflicts, or disappointment.

Instead, disinheritance is allowed only when the Civil Code expressly authorizes it, and only if the strict legal requirements are followed. Failure to comply with these requirements can invalidate the disinheritance and restore the compulsory heir’s right to inherit.

If you are preparing a will, planning your estate, or considering whether a family member may legally be disinherited, understanding the law is essential.

What Is Disinheritance Under Philippine Law?

Disinheritance is the formal act of depriving a compulsory heir of his or her legitime through a valid will.

Unlike merely choosing not to leave property to someone, disinheritance specifically affects persons whom the law ordinarily requires to inherit.

Article 916 of the Civil Code provides:

“Disinheritance can be effected only through a valid will wherein a legal cause therefor shall be specified.”
— Civil Code, Article 916

This means that a compulsory heir cannot lose his or her inheritance unless the disinheritance appears in a valid will and is supported by a legally recognized cause.

Who Can Be Disinherited Under Philippine Law?

Not every heir needs to be “disinherited.”

Philippine succession law distinguishes between:

Compulsory Heirs

These heirs are protected by law and are generally entitled to receive their legitime. Depending on the circumstances, compulsory heirs include:

1. Legitimate children and descendants;
2. Legitimated children;
3. Certain illegitimate children;
4. Surviving spouse;
5. Legitimate parents or ascendants.

Because their shares are reserved by law, they cannot be deprived of their legitime unless a valid disinheritance exists.

Voluntary Heirs

A voluntary heir inherits only because the testator names that person in a will.

Since voluntary heirs have no reserved share, they may simply be omitted from the will without the need for formal disinheritance.

Legal Requirements to Disinherit an Heir Under Philippine Law

Because disinheritance removes rights expressly protected by law, Philippine courts require strict compliance with the Civil Code.

1. The Disinheritance Must Appear in a Valid Will

The Civil Code requires that disinheritance be made only through a valid testament.

Whether the will is notarial or holographic, it must satisfy all legal formalities.

In Seangio v. Reyes, G.R. Nos. 140371-72 November 27, 2006 the Supreme Court recognized that a document intended primarily to disinherit an heir may qualify as a holographic will if it is entirely handwritten, dated, and signed by the testator.

2. The Will Must State a Legal Cause

Merely stating that a child or spouse is “disowned” is legally insufficient.

Article 916 requires that the will expressly identify the legal ground for disinheritance.

If the stated reason is not among those recognized by law, the disinheritance is void.

3. The Cause Must Be One Expressly Allowed by the Civil Code

Article 918 provides that a disinheritance is ineffective if:

1. no cause is stated;
2. the stated cause is not recognized by law; or
3. the alleged cause is false.

The Supreme Court reiterated this principle in Manguerra v. Manguerra-Aberasturi,G.R. No. 253426. November 29, 2022 where the Court ruled that because the alleged reason for disinheritance did not fall within the exclusive statutory grounds provided by the Civil Code, the affected heirs remained entitled to their legitime.

The decision underscores an important rule:

Courts cannot create new grounds for disinheritance beyond those expressly provided by law.

4. The Cause Must Be Proven if Challenged

Article 917 of the Civil Code places the burden of proof on the heirs who seek to uphold the disinheritance.

If the disinherited compulsory heir denies committing the alleged acts, those invoking the validity of the will must establish the truth of the stated cause through competent evidence.

Failure to prove the allegations may invalidate the disinheritance.

Legal Grounds for Disinheriting a Child or Descendant

Article 919 of the Civil Code provides the exclusive grounds for disinheriting children and descendants.

Among the recognized causes are:

1. Attempt against the life of the testator, spouse, ascendants, or descendants;
2. False accusation of a serious criminal offense;
3. Adultery or concubinage with the testator’s spouse;
4. Fraud, violence, intimidation, or undue influence in making the will;
5. Unjustified refusal to support the parent;
6. Maltreatment by word or deed;
7. Living a dishonorable or disgraceful life;
8. Conviction carrying civil interdiction.

In Seangio v. Reyes, G.R. Nos. 140371-72 November 27, 2006 , the Supreme Court considered repeated acts of serious verbal maltreatment as falling within the statutory ground of “maltreatment by word or deed” under Article 919.

Legal Grounds for Disinheriting Parents or Ascendants

Article 920 governs disinheritance of parents and ascendants.

Recognized causes include:

1. Abandonment of children;
2. Attempt against the child’s virtue;
3. Attempt against the life of the testator;
4. False criminal accusation;
5. Adultery or concubinage with the spouse of the testator;
6. Undue influence over the making of the will;
7. Loss of parental authority under the Civil Code;
8. Refusal to provide legally required support.

These grounds are exclusive.

Legal Grounds for Disinheriting a Spouse

Article 921 of the Civil Code allows disinheritance of a spouse only for specific statutory causes, including:

1. Attempt against the life of the testator;
2. False criminal accusation;
3. Giving grounds for legal separation;
4. Undue influence in making the will;
5. Loss of parental authority;
6. Unjustified refusal to support the family.

Personal incompatibility or marital disagreements alone are generally insufficient.

What Happens if the Disinheritance Is Invalid?

A defective disinheritance does not automatically invalidate the entire will.

Instead, Article 918 provides that the institution of heirs may be annulled only insofar as it prejudices the compulsory heir who was improperly disinherited.

The remaining provisions of the will may continue to be valid if they do not impair the compulsory heir’s legitime.

This is why properly drafting the will is critical.

A single mistake in identifying or proving the legal cause may substantially alter the distribution of an estate.

Common Misconceptions About Disinheritance

Many people mistakenly believe they may disinherit an heir simply because:

1. the child rarely visits;
2. family relationships have deteriorated;
3. one child is financially successful;
4. there are longstanding family disputes;
5. they feel “disrespected.”

Under Philippine law, none of these reasons automatically justify disinheritance.

Only the specific causes found in Articles 919, 920, and 921 of the Civil Code may legally deprive a compulsory heir of his or her legitime.

Estate Planning Tips Before Disinheriting an Heir

Before deciding to disinherit a compulsory heir, consider the following:

1. Determine whether the intended beneficiary is truly a compulsory heir.
2. Confirm that the facts satisfy one of the statutory grounds under the Civil Code.
3. Prepare a legally valid notarial or holographic will.
4. Clearly identify the compulsory heir being disinherited.
5. State the precise legal cause under the applicable Civil Code provision.
6. Preserve evidence supporting the alleged ground should the will later be contested.

Professional legal advice can help avoid costly probate litigation and ensure that the testator’s wishes are carried out according to law.

Frequently Asked Questions (FAQs)

Final Note

Can you disinherit an heir under Philippine law? Yes—but only if the compulsory heir is disinherited through a valid will, the legal ground expressly recognized by the Civil Code is stated, and that ground can be proven if challenged. Because Philippine law strongly protects the legitime of compulsory heirs, any attempt to disinherit someone outside the narrow grounds provided by Articles 916 to 921 of the Civil Code is likely to fail.

Proper estate planning today can prevent expensive inheritance disputes tomorrow.
