How to Disinherit a Child in Spain: Valid Legal Grounds

🇪🇸 Read the original in Spanish

The decision to deprive a descendant of their share of an inheritance is one of the most difficult and complex choices a person can face within the family sphere. In Spain, succession law fiercely protects forced heirs through the concept of the legítima (forced share/statutory legacy), which prevents a testator from freely disposing of all their assets without a legally specified justification. Understanding the strict requirements, the grounds set out in the Código Civil (Civil Code), and the most recent rulings of the courts is essential to prevent a last will and testament from being declared void in court.

The System of Forced Shares (Legítimas) under Spanish Common Law

To understand how you can disinherit a child, you must first understand the inheritance framework that governs most of the national territory (under the Código Civil). A person's estate is divided by law into three perfectly distinct thirds:

1. *The tercio de legítima estricta (strict forced share third):* This is the portion of the assets that the law obligatorily reserves for forced heirs (primarily, children and descendants). This third must be divided equally among all children.
2. *The tercio de mejora (improvement third): This is used to benefit one or more children or descendants over the others. If it is not used to "improve" anyone's share, it joins the legítima estricta, forming what is known as the "legítima amplia*" (broad forced share, which constitutes two-thirds of the total estate).
3. *The tercio de libre disposición (free disposal third):* This is the only part of the assets (one-third) over which the testator has absolute freedom to leave to whomever they wish, whether a family member, a stranger, or a charitable institution.

Disinheriting, in the strict sense, means legally depriving a forced heir of their right to receive even the legítima estricta. Because this is an exceptional measure that goes against the legal protection of the family, the Código Civil requires it to be carried out under highly formal conditions and solely for the grounds expressly provided for by law.

Legal Grounds to Disinherit a Child According to the Civil Code

The Spanish Código Civil regulates disinheritance in Articles 848 to 857. Article 848 clearly establishes that disinheritance can only take place for one of the causes expressly designated by law. This means that disinheritance based on simple dislike, estrangement, or lack of affinity is not valid unless it fits into one of the legally defined scenarios.

The grounds are divided into two large blocks: general grounds of unworthiness to succeed (indignidad para suceder) and specific grounds to disinherit children and descendants.

1. General grounds of unworthiness (Article 756 of the Civil Code)

These grounds are so serious that they disqualify the heir from succeeding the deceased, and Article 852 assimilates them as valid grounds for disinheritance. The most notable include:

• Having been convicted by a final judgment (sentencia firme) for attempting to take the life of, or sentenced to a serious penalty for causing injury or habitually inflicting physical or psychological violence within the family environment upon, the testator, their spouse, a person bound by a similar relationship of affectivity, or their ascendants or descendants.
• Having been convicted by a final judgment for crimes against freedom, moral integrity, and sexual freedom and indemnity, if the victim is any of the persons mentioned above.
• Accusing the testator of a crime for which the law prescribes a severe penalty, if convicted of a false accusation (denuncia falsa).
• Forcing the testator, through threats, fraud, or violence, to make a will or to change it.
• Preventing another person, by the same means, from making a will, revoking one already made, or supplanting, hiding, or altering a subsequent one.

2. Specific grounds to disinherit children and descendants (Article 853)

Article 853 of the Civil Code contains two specific grounds of enormous practical relevance:

• *Having refused, without legitimate reason, to provide maintenance/support (alimentos)* to the parent or ascendant who is disinheriting them. This does not only refer to court-ordered child support, but to basic sustenance, housing, clothing, and medical assistance in situations of need.
• *Having physically abused (maltratado de obra) or seriously insulted in words (injuriado gravemente de palabra)* the parent or ascendant.

Jurisprudential Evolution: Psychological Abuse and Emotional Abandonment

For decades, physical abuse (maltratado de obra) was restrictively interpreted as physical aggression. However, the Tribunal Supremo (Supreme Court), in a doctrine now consolidated since its landmark rulings of 2014 and 2015, has equated psychological abuse to physical abuse.

The jurisprudence of the Tribunal Supremo determines that emotional abandonment of parents by their children, the lack of a continuous relationship, and absolute and repeated contempt constitute an impairment of the testator's mental health that fits within psychological abuse. For this ground to be valid, the estrangement must be exclusively attributable to the child and must have caused real, demonstrable psychological suffering to the parent.

The Impact of Regional Laws (Derechos Forales) in Spain

Spain has great legislative diversity in civil matters. If the testator has their vecindad civil (civil residence/status) in an autonomous community with its own regional law (derecho foral), the rules regarding the legítima and disinheritance vary substantially:

• Catalonia: The legítima is only one-quarter (25%) of the value of the estate (to be divided among all children). The Código Civil de Cataluña (Civil Code of Catalonia) includes as a specific ground for disinheritance the manifest and continuous absence of a family relationship between the deceased and the beneficiary, if it is due to a cause exclusively attributable to the beneficiary.
• Basque Country: Since the Basque Civil Law of 2015, there is almost absolute freedom. The collective legítima is one-third, but the testator can freely choose just one of their children or grandchildren and set aside (tacitly disinherit) the others without needing to allege any grounds.
• Galicia: The legítima of the children is 25% of the estate. The grounds for disinheritance follow a line similar to that of the common Civil Code.
• Navarra: There is almost absolute civil freedom. The "legítima navarra" is purely formal or symbolic (the attribution of "five sueldos febles or carlines for movable property and one robada of land for real estate"), meaning it is not necessary to formally disinherit a child to deprive them of actual assets.

Practical Step-by-Step Steps to Disinherit a Child

For a disinheritance to be legally valid and withstand potential future court challenges, these steps must be strictly followed:

1. Draft a formal will: Disinheritance can never be done verbally or in a private document. It must obligatorily be expressed in a will (preferably an open will, testamento abierto, before a Notario).
2. Clearly identify the disinherited person: The child or descendant being deprived of their legítima must be designated by their full first name and surnames.
3. Express the specific legal ground: You must explicitly invoke the article of the Código Civil (or the applicable regional law) and describe the specific cause (for example, "for psychological abuse and emotional abandonment, in accordance with Article 853.2 of the Civil Code"). Generic formulas are not sufficient.
4. Gather and preserve evidence during your lifetime: Since the testator will not be present when the succession opens, it is vital to prepare evidence proving the ground for disinheritance (text messages, emails, letters, psychological or medical reports confirming the testator's suffering, notary demands, or third-party testimonies).

Deadlines, Amounts, and Key Figures in the Process

The succession and disinheritance process is subject to strict time and financial limits that should be understood in detail:

• Deadline to challenge the disinheritance: A disinherited child who believes the grounds are false has a period of 5 years (in common Civil Code territory) to file a lawsuit challenging the will, counting from the moment the succession opens (the death of the testator) or from when they become aware of the will. In Catalonia, this limitation period (plazo de caducidad) is 4 years.
• The burden of proof: If the disinherited person denies the grounds, the burden of proof does not fall on them, but on the other heirs designated in the will. They must prove before a judge that the grounds alleged by the deceased were real.
• The transmission effect (Article 857 of the Civil Code): If the disinherited child has, in turn, children or descendants (the testator's grandchildren), these grandchildren will step into their parent's shoes and retain the right to the legítima estricta that corresponded to the parent. The assets are not automatically distributed among the other siblings; instead, they are transmitted vertically to the lineage of the disinherited child.
• *Inheritance and Gift Tax (Impuesto sobre Sucesiones y Donaciones - ISD): If the disinheritance is declared void by a judge, the child will recover their right to the legítima*. Upon inheriting, they will pay tax according to the regulations of their Autonomous Community. If the disinheritance is valid and the grandchildren inherit that portion, they will likewise benefit from Group II kinship status (descendants), enjoying tax bonuses of up to 99% that exist in regions like Madrid, Andalusia, or the Valencian Community.

Practical and Numerical Examples

To visualize the financial impact of a disinheritance, we analyze two scenarios based on an estate subject to the common Civil Code.

Example 1: Succession with valid disinheritance and transmission to grandchildren

Let us imagine that Don Manuel passes away with a net estate valued at €300,000. Don Manuel had two children, Carlos and Sofía. Carlos has two children (Manuel's grandchildren). Don Manuel legitimately disinherited Carlos in his will due to continuous psychological abuse, providing medical reports regarding his anxiety state, and named his daughter Sofía as his sole universal heir.

• The estate of €300,000 is theoretically divided into three thirds of €100,000 each (Legítima estricta, Mejora, and Libre Disposición).
• Since Carlos is validly disinherited, his right to the legítima estricta does not disappear from the succession map; instead, it is transmitted to his two children (Manuel's grandchildren) by right of representation (derecho de representación, in accordance with Article 857 of the Civil Code).
• The total legítima estricta is €100,000 (one-third of the total). Under normal conditions, €50,000 would go to Carlos and €50,000 to Sofía.
• Applying the disinheritance, Carlos's two children receive their father's share in equal parts: €25,000 for each grandchild.
• Sofía receives her share of the legítima estricta (€50,000), plus the tercio de mejora (€100,000) and the tercio de libre disposición (€100,000) that her father assigned to her in the will.
• Final Result: Sofía receives €250,000 and the two grandchildren receive €25,000 each. Carlos receives €0.

Example 2: Successful challenge due to lack of evidence

Suppose Doña Carmen passes away leaving an estate of €180,000 and two children, Javier and Marta. In her will, Doña Carmen disinherits Javier, alleging "lack of relationship and contempt," naming Marta as the heir to everything. However, Doña Carmen left no proof of psychological abuse, and the estrangement was mutual following a conflictive divorce.

• After her death, Javier files a lawsuit challenging the will within the 5-year deadline.
• In court, Marta (the heir) fails to prove that the estrangement was Javier's exclusive fault or that it caused pathological harm to her mother.
• The judge declares the disinheritance void. Javier recovers his right to the legítima estricta.
• The legítima estricta is €60,000 (one-third of €180,000), to be divided between the two siblings.
• Final Result: Javier has the right to obligatorily receive €30,000. Marta keeps the remaining €150,000 (her share of the legítima plus the thirds of mejora and libre disposición, which remained valid in the will).

Errors You Must Avoid

When starting a disinheritance process, it is very common to make technical mistakes that end up invalidating the testator's last wishes. Avoid the following errors:

• Using generic or subjective justifications: Phrases like "I disinherit my child because they do not speak to me" or "because they are a bad person" have no legal validity. The cause must fit strictly within the scenarios of Articles 756 or 853 of the Civil Code.
• Failing to gather documentary evidence during your lifetime: Relying on the other heirs to "manage somehow" to prove the abuse in court is a critical mistake. Without messages, emails, police reports, or medical files, defending the disinheritance against a challenge is extremely difficult.
• Forgetting that grandchildren inherit the forced share: Thinking that by disinheriting a child, the money goes entirely to the other siblings. If the disinherited person has descendants, the grandchildren will take their place by law, unless valid grounds for disinheritance also exist against them.
• Proceeding to a formal reconciliation without weighing the consequences: Article 856 of the Civil Code establishes that a subsequent reconciliation between the offender and the offended party deprives the testator of the right to disinherit and renders any already executed disinheritance without effect. If, after making the will, there is a documented reconciliation (for example, affectionate messages back and forth), the disinheritance will be automatically annulled.

Frequently Asked Questions (FAQ)

Can you disinherit a child absolutely so they receive nothing at all?

Yes. If one of the valid legal grounds is met and it is done through a formal will, the disinherited child loses all rights to the legítima estricta, the tercio de mejora, and the tercio de libre disposición. They will receive €0 from their parent's estate. However, if this child has descendants, their share of the legítima estricta will pass to their own children (the testator's grandchildren).

What happens if the disinherited child does not agree with the will?

The disinherited child has the full right to challenge the will in the civil courts once the testator has passed away. To do so, they have a deadline of 5 years in common territory. In the trial, the heirs designated in the will will have the legal obligation to prove that the grounds for disinheritance alleged by the deceased were true.

Can you disinherit a child simply for not having a relationship with them?

Under the common Civil Code, mere estrangement or lack of an affectionate relationship is not an independent ground for disinheritance. However, Supreme Court jurisprudence allows disinheritance if this continuous estrangement over time is of such severity that it generates family suffering comparable to psychological abuse, provided that the lack of relationship is exclusively attributable to the child. In Catalonia, by contrast, the lack of a continuous relationship is expressly listed as a ground for disinheritance in its own Civil Code.

Is it possible to revoke a disinheritance if the parent and child reconcile?

Yes. Reconciliation between the testator and the disinherited child immediately renders the disinheritance without effect, as established by Article 856 of the Civil Code. To ensure the revocation is fully secure and does not generate legal doubts after death, the ideal approach is for the testator to grant a new will, revoking the previous one and once again naming the reconciled child as an heir or beneficiary.

In Summary

• *The legítima is a protected right:* In Spain, the law obligatorily reserves a portion of the estate for children, limiting the testator's freedom.
• Grounds specified by law: To deprive a child of their legítima, you must invoke an express ground from the Civil Code (Articles 756 or 853), such as non-payment of maintenance or physical/verbal abuse.
• Psychological abuse is valid: The Supreme Court equates emotional abandonment and continuous contempt to physical abuse, opening the door to disinheritance due to an absence of relationship attributable to the child.
• The importance of evidence: It is essential to gather documentary, medical, and testimonial evidence during your lifetime so that the heirs can defend the disinheritance in the event of a challenge.
• Representation effect: Disinheriting a child does not prejudice their own descendants; the testator's grandchildren will inherit the legítima estricta that corresponded to the disinherited person.
• Deadline to challenge: The disinherited child has a period of 5 years (4 years in Catalonia) to claim their share in court after the death.
