Inheritance in Spain in 2026

Owning property in Spain is about more than just sunshine and investments; it entails legal responsibility that does not disappear upon the owner’s death. It is precisely during the inheritance stage that foreigners most frequently encounter difficulties: unexpected taxes, mandatory shares for relatives, missed deadlines, and conflicts among heirs.

In this article, we analyze how Spanish inheritance law works in 2026, the taxes that await non-residents, and what can be done in advance to protect your assets and your family’s interests.

Inheritance in Spain: A High-Risk Legal Area

The Spanish inheritance model differs significantly from systems used in many other countries.

• There is strict protection for close relatives.
• Inheritance tax depends not only on the amount but also on the region and the degree of kinship.
• Errors in a will can lead to the automatic application of Spanish law—even if the deceased was a foreigner.

That is why inheritance planning in Spain cannot be left to chance.

The Mandatory Share (“Legítima”): What Cannot Be Bypassed

Spanish civil law is based on the principle of family protection. Its key element is the mandatory inheritance share (legítima). The concept is simple: a portion of the assets cannot be freely bequeathed to third parties if the deceased has close relatives.

The estate is theoretically divided into three equal parts:

• The Strict Legal Reserve (Legítima): Reserved for children and distributed equally among them.
• The Betterment Share (Tercio de Mejora): Also addressed to descendants, but the testator may determine the proportions themselves.
• The Free Disposal Share (Libre Disposición): The only portion that can be distributed without restrictions.

For foreigners, this often comes as an unpleasant surprise, especially if their country of origin allows for complete testamentary freedom.

Inheritance Without a Will (Intestacy)

If a property owner in Spain dies without leaving a will, the order of succession established by law comes into force. This applies to non-residents as well. The sequence is as follows:

1. Children and grandchildren
2. Parents and other ascendants
3. Spouse
4. Siblings, nephews, and nieces
5. The State

It is important to understand that the citizenship, place of residence, or language of the heirs does not matter. In the absence of a will, Spanish law applies automatically.

The Option to Choose Your National Law

Of key importance for non-residents is EU Regulation No. 650/2012, which remains in force in 2026. It allows you to:

• choose the law of your country of citizenship,
• apply it to the entire estate, including real estate in Spain,
• avoid mandatory shares if they are not provided for in your national law.

Important: This choice must be explicitly stated in the will. If this is not done, the Spanish model applies.

Inheritance Tax: Recent Changes

Inheritance Tax (Impuesto sobre Sucesiones y Donaciones) is still charged, but the amount varies greatly. The principle applies: the more distant the relationship, the higher the tax and the fewer the allowances.

Main groups of heirs:

• Group I: Children under 21 years old
• Group II: Spouses, adult children, parents
• Group III: Siblings, nephews, nieces
• Group IV: Distant relatives and unrelated persons

The Autonomous Community (region) where the property is located plays a decisive role. For example, Madrid and Andalusia retain significant tax bonuses for close relatives, whereas in some regions, the rate for distant heirs can reach 30–34%.

You cannot completely avoid the tax, but it can be significantly reduced with proper planning. In practice, allowances are applied for the family’s main residence (up to 95%), regional tax coefficients, personal tax-free allowances, and correct property valuation. Often, it is an incorrect strategy that leads to overpayment, rather than the tax itself.

The Procedure for Inheriting Real Estate

Foreign heirs must follow a strictly defined sequence of actions:

1. Obtaining an NIE: Without it, neither taxes nor registration are possible
2. Requesting the Certificate of Last Wills (Certificado de Últimas Voluntades)
3. Notarizing the Acceptance of Inheritance
4. Payment of tax (usually within 6 months)
5. Registration of title in the Property Registry

Missing deadlines or formal requirements almost always results in fines and delays.

Inheritance Planning: A Professional Approach

If you have assets in Spain, it would be wise to:

• execute a Spanish or international will,
• explicitly specify the applicable law,
• assess tax consequences in advance,
• take regional specificities into account, and
• not delay consultation until it is too late to correct mistakes.

Spanish inheritance law in 2026 remains strict, formalized, and sensitive to detail. Even with a will, errors in wording or choice of law can lead to financial losses and conflicts among heirs.

Competent planning is not a formality, but a tool to protect your family and assets. That is why the support of experienced lawyers in Spanish inheritance and tax matters is not a luxury, but a necessity.
