Indignidad Sucesoria in Spain in 2026: When an Heir Is Disqualified Under CC Article 756

Spanish succession law recognises that not everyone named in a will, or entitled to inherit by law, deserves to receive the estate. The Código Civil provides a mechanism called indignidad sucesoria: a legal sanction that strips inheritance rights from a person who has committed grave acts against the deceased, their spouse, their partner, or their descendants or ascendants. It is regulated in Articles 756, 757, 758, 760, 761 and 762 of the Código Civil and applies to both testate and intestate succession. Unlike desheredacion, which requires an express clause in the will, indignidad operates by operation of law and requires a judicial declaration on the initiative of any party with a legitimate interest in the estate.

What are the seven causes of indignidad sucesoria under CC Article 756?

Article 756 of the Código Civil lists seven causes that render a person incapable of succeeding by reason of indignity. Each cause is tightly defined and most require a final criminal conviction, making indignidad a remedy that cannot be triggered by moral disapproval alone.

The seven causes, as they stand after the reforms introduced by Ley 15/2015 and Ley 8/2021, are:

Cause	Conduct	Requires conviction?
1	Attempting against the life of the deceased, spouse, partner or descendants or ascendants; or causing serious injuries; or habitual physical or psychic violence in the family sphere	Yes, final sentence
2	Crimes against liberty, moral integrity, sexual freedom or indemnity against the same persons; also serious crimes against family rights and duties; also removal from parental authority, guardianship, foster care or curatela for imputable reasons	Yes, final sentence or resolution
3	Accusing the deceased of a crime carrying a serious penalty, if convicted for false denunciation	Yes, final sentence for false denunciation
4	An heir of legal age who, knowing of the violent death of the testator, failed to report it to the authorities within one month	No conviction, but one-month window
5	Using threat, fraud or violence to force the testator to make or change a will	Criminal conduct, judicial proof
6	Using the same means to prevent another from making a will, or to supplant, conceal or alter a later will	Criminal conduct, judicial proof
7	In the succession of a person with a disability, those entitled to inherit who failed to provide the care due under CC Articles 142 and 146	No conviction, judicial assessment of care duties

The seventh cause was added by Ley 41/2003 and modified by Ley 8/2021, which brought the concept of disability into line with the supported decision-making framework. The first three causes were reformulated by Ley 15/2015, which expanded the scope to include habitual family violence and crimes against sexual freedom, reflecting the modern criminal code’s structure.

How does indignidad sucesoria differ from desheredacion?

The two mechanisms produce the same outcome, exclusion from the inheritance, but they operate through fundamentally different legal routes. Understanding the distinction matters for anyone involved in an inheritance dispute or contesting a will in Spain, because the procedural requirements and the available causes are not identical.

Feature	Indignidad sucesoria (CC Art 756)	Desheredacion (CC Art 852)
Source of disqualification	By operation of law	By express clause in the will
When it takes effect	After judicial declaration	At the testator’s initiative, expressed in the will
Applies to testate succession	Yes	Yes
Applies to intestate succession	Yes	No
Causes available	All seven in Art 756	Only causes 1, 2, 3, 5 and 6 (per Art 852)
Pardon by testator	Tacit or express (Art 757)	Reconciliation expressly stated in the will (Art 855)

The critical difference is that Article 852 of the Código Civil explicitly limits the just causes for desheredacion to indignidad causes numbered 1, 2, 3, 5 and 6. Causes 4 (failure to report a violent death) and 7 (neglect of a disabled person) are available only as grounds for indignidad, not for desheredacion. This means a testator cannot disinherit a child solely for failing to report their parent’s violent death, but a court can declare that person unworthy to inherit.

Another practical difference is that indignidad can be invoked even when there is no will at all, because it applies to intestate succession. If someone would inherit under the forced heirs rules of Spanish succession law but has committed one of the Article 756 acts, any co-heir or interested party can seek a judicial declaration of indignidad.

Who can bring an action for indignidad and what is the time limit?

The action to declare indignidad is brought by any person with a legitimate interest in the estate, typically a co-heir, a legatee, or a creditor of the estate. The Código Civil does not leave the declaration to private agreement: a judge must determine that one of the Article 756 causes is established on the evidence.

Under CC Article 758, the capacity of the heir or legatee is assessed at the time of the death of the person whose succession is at stake. For causes 2 and 3, the court waits for the final criminal sentence before assessing capacity. For cause 4, it waits for the one-month reporting period to expire. If the institution of the heir or the legacy is conditional, capacity is also assessed at the time the condition is fulfilled.

The prescription rule is in CC Article 762: no action to declare incapacity may be brought after five years from the date the incapable person took possession of the inheritance or legacy. This five-year period runs from the moment of possession, not from the date of death, which can be significant in cases where the disqualified person entered the estate months or years after the succession opened.

What must a disqualified heir return under CC Article 760?

A person declared incapable of succeeding who has already taken possession of hereditary assets must return them. CC Article 760 is specific about the scope of the restitution: the assets must be returned with their accessories (for example, improvements made to a property) and with all the fruits and rents collected during the period of possession.

This means that if the disqualified person inherited a flat and rented it out, they must return both the flat and the rental income collected. If they inherited shares and received dividends, those dividends must be returned. The restitution is comprehensive and mirrors the civil law principle that a person who possesses in bad faith, or against a legal prohibition, must account for all economic benefits derived from the assets.

For non-residents inheriting Spanish property, the practical implication is that the restitution obligation extends to any rental income generated by a Spanish property during the period the disqualified person held it, and the property must be re-registered in the name of the substitute heir through the partition of inheritance process.

Can the testator pardon an heir who would otherwise be disqualified?

Yes. CC Article 757 provides that the causes of indignidad cease to have effect in two situations. The first is tacit pardon: if the testator knew of the cause of indignity at the time of making the will and still named the person as heir, the disqualification is extinguished. The second is express pardon: if the testator learned of the cause after making the will, they can remit it in a public document.

Tacit pardon is significant because it means the testator’s knowledge and conduct at the moment of making the will can override a serious cause of indignity. If a father knew that his son had been convicted of a violent crime against him but still appointed the son as heir in a subsequent will, the indignidad cause is extinguished and cannot be invoked by other heirs after the father’s death.

Express pardon requires a public document, which in practice means a notarial act or a will containing an express remission. A private letter or an oral statement would not satisfy the Article 757 requirement. This is consistent with the formal character of Spanish succession acts, which generally require notarial or public instruments for acts that alter the disposition of an estate.

What happens to the children of a disqualified heir?

CC Article 761 addresses the situation where the person excluded for incapacity is a child or descendant of the testator and has their own children or descendants. In that case, those descendants acquire the right to the legitima in place of the excluded parent.

This right of representation is personal to the excluded person’s lineage and does not extend the disqualification downward. The grandchildren do not inherit because the parent was forgiven or because the disqualification was lifted; they inherit because Spanish law treats the exclusion as personal to the person who committed the grave act, not as a taint that passes to the next generation.

The legitima, as explained in the forced heirs guide, is the portion of the estate that the law reserves for forced heirs. In common-law Spain, it amounts to two-thirds of the estate for descendants: one-third divided equally among all children (the legitima strictu sensu) and one-third applied to improve the shares of the children (the mejora). The disqualified parent’s share passes to their children through representation, preserving the legitima for that branch of the family.

What does the cross-border picture look like for non-resident heirs?

Indignidad sucesoria is a matter of the substantive succession law that governs the estate, not a procedural rule. Under the EU Succession Regulation (Regulation 650/2012), the law applicable to a succession is the law of the deceased’s habitual residence at death, unless the deceased made a choice of law in favour of their nationality. If Spanish law governs the succession, the indignidad provisions of the Código Civil apply regardless of where the heirs live.

For a non-resident heir involved in a Spanish succession, the practical steps are to file the Modelo 650 inheritance tax return within the six-month deadline, to notify the notary or court of any potential indignidad cause, and to seek a judicial declaration if a co-heir or interested party objects to the disqualified person’s participation. The 99 per cent bonificacion for close relatives under Andalusian inheritance tax applies to the tax due, but it does not override a judicial declaration of indignidad, which is a question of succession law, not tax law.

The five-year prescription in Article 762 means that a co-heir discovering a cause of indignity years after the estate was distributed may still have a viable action, provided the disqualified person entered possession less than five years ago. The action is civil, brought before the courts of the place where the succession is being processed, and the burden of proof rests on the party asserting the cause.
