Common mistakes expats make with Spanish wills

Many expatriates who invest or settle in Spain are not fully aware of the legal risks associated with poor succession planning. In practice, some of the most common mistakes with Spanish wills are only discovered after the owner of the assets has passed away, when it is no longer possible to correct them. At that stage, these issues often lead to family disputes, unnecessary delays in the inheritance process, and a higher tax burden for heirs.

Understanding the most common mistakes with Spanish wills from the outset allows you to protect your assets, ensure that your estate in Spain is distributed according to your wishes, and avoid legal complications that can affect your family for years.

In this article, we explain the most frequent mistakes foreign nationals make when dealing with Spanish wills, based on practical legal experience, so you can make informed decisions and avoid problems in the future.

Why making a Spanish will is essential for expats

Protecting your assets in Spain

A Spanish will allows you to deal specifically with the assets you hold in Spain, regardless of whether you already have a will in your home country. This separation is often crucial in practice, particularly when real estate or significant investments are involved, as it helps avoid many common mistakes in Spanish wills that arise from overlapping or conflicting documents.

Putting the right structure in place also makes a tangible difference later on. Clear planning can simplify administrative steps for your heirs, including situations where a power of attorney in Spain is required to manage or transfer assets, reducing delays and helping the process move forward with fewer complications.

Avoiding legal uncertainty for heirs

Complying with the Spanish will requirements for foreigners helps prevent heirs from facing lengthy, costly, and often complex legal procedures, particularly when they are based outside Spain. Without a properly structured Spanish will, even relatively straightforward estates can become difficult to manage, requiring additional documentation, translations, and legal steps that delay the distribution of assets.

Complementing your foreign will

One common mistake in Spanish wills is assuming that a will drafted in another country is sufficient to address assets in Spain. In practice, relying solely on a foreign will can create complications during the inheritance process, especially when it needs to be recognised and applied under Spanish law.

A Spanish will should be designed to complement, not contradict, any existing will in your country of origin. When both documents are aligned, the administration of the estate becomes significantly more efficient, reducing the risk of conflicts, delays, or unintended outcomes for your heirs.

Mistake 1 – Not making a Spanish will at all

Relying only on a will from your home country

Relying exclusively on a will drafted in your home country is one of the most common mistakes with Spanish wills among expatriates. While a foreign will may be legally valid, its execution in Spain is often slower, more complex, and less tax-efficient.

In practice, this can mean additional administrative steps, the need for legalisation and translation of documents, and delays that could otherwise be avoided with a properly structured Spanish will.

Legal consequences for your estate

Without a Spanish will, your estate in Spain is handled in accordance with the rules of private international law, which determine which legal system applies to the succession. This can lead to conflicts over applicable law, outcomes that do not reflect your intentions, and, in some cases, a higher tax burden for your heirs.

Mistake 2 – Not choosing applicable law

Another common issue arises from failing to address which law should govern the succession. Under European regulations, foreign nationals may elect the law of their nationality to govern their estate. However, failing to make this choice explicit is one of the most common mistakes in Spanish wills, with significant legal consequences.

The law that applies to your succession directly determines how your estate is distributed, including who inherits and in what proportions. Without a clear election, the outcome may differ substantially from what you intended.

How to state your chosen national law

To be valid, the choice of applicable law must be expressly included in the Spanish will through a specific clause. This is a key element in meeting the Spanish will requirements for foreigners and ensuring that your wishes are properly reflected.

If no such clause is included, Spanish law will apply by default. In many cases, this leads to an estate distribution that can differ considerably from the rules of the testator’s home country

Mistake 3 – Not updating your will after changes

A Spanish will should not be treated as a one-time document. Significant personal or financial changes often require a review, and in many cases, a full update. Events such as purchasing a new property, moving to a different autonomous region, or changes in your marital status can quickly make an existing will outdated.

Marriage, divorce, or property acquisition

Life changes such as marriage, divorce, the birth of children, or acquiring new property in Spain can fundamentally alter the balance of an existing estate plan. Failing to reflect these changes in your will is a common mistake in Spanish wills and can lead to unintended consequences.

Common situations where this becomes an issue include:

• Marriage: A will made before marriage may not adequately protect the surviving spouse or reflect their rights
• Divorce: Retaining outdated provisions can result in former partners remaining as beneficiaries, creating legal complications and potential disputes
• Property acquisition: Purchasing a new property in Spain without revising the will can create uncertainty around how that asset should be divided

Property ownership, in particular, often introduces additional complexity. Many expatriates acquire second homes or investment properties in Spain without revisiting their will, which can lead to practical difficulties later on. This is especially relevant when heirs are based in different countries and subject to different legal systems, particularly in situations such as how to split inherited property between siblings in Spain.

Reviewing and updating your will after any significant change ensures that it remains aligned with your current circumstances. It also helps meet the Spanish will requirements for foreigners while reducing the risk of family disputes, notarial issues, and unnecessary delays in estate administration.

Mistake 4 – Inheritance tax miscalculations

Mistakes related to inheritance tax are particularly common among expatriates and often have the greatest financial impact on heirs. In many cases, the complexity of the Spanish tax system and its regional variations are underestimated, leading to higher-than-necessary tax payments or even penalties due to inadequate planning.

Overlooking regional tax reductions in Spain

In Spain, inheritance tax is devolved to the autonomous communities, meaning that each region applies its own rules, reductions, and allowances. As a result, the tax burden can vary significantly depending on where the estate is located or where the tax is triggered.

Ignoring these regional differences is one of the common mistakes with Spanish wills that generates the highest costs. In practice, errors often arise when applying reductions or exemptions, particularly when comparing regions such as Andalusia, Madrid, or Murcia (where more favourable regimes may apply) with other regions where the effective tax burden is higher.

Planning ahead to minimise liability

With proper succession planning, aligned with the Spanish will requirements for foreigners, it is possible to reduce the tax burden for heirs in a fully legal and structured way. Anticipating how inheritance tax will apply to your estate allows for more efficient decision-making and helps avoid unexpected costs at the time of succession.

Mistake 5 – Improper wording or invalid structure

Using templates without legal review

Relying on generic templates downloaded online or adapting wills from other jurisdictions is a significant risk. These documents rarely reflect the specific requirements of Spanish succession law and often fail to meet the requirements for a Spanish will for foreigners.

In practice, a poorly drafted will can create serious issues, including:

• Difficulties in clearly identifying heirs
• Errors or ambiguities in the description of assets
• Clauses that are fiscally inefficient
• Provisions that conflict with mandatory rules under Spanish law

Rather than simplifying the process, these mistakes often have the opposite effect: delays in estate distribution, increased legal costs, and potential disputes among heirs.

The risk becomes even greater in cross-border situations, particularly when trying to align the law of the testator’s home country with inheritance tax for non-residents in Spain. Without proper legal adaptation, the will may not produce the intended effects in Spain, forcing heirs to undertake additional legal steps to resolve issues that could have been avoided with appropriate professional guidance from the outset.

Mistake 6 – Excluding forced heirs unintentionally

Unintentionally excluding forced heirs is one of the most delicate and at the same time, most common mistakes with Spanish wills among expatriates. This issue often arises from a lack of familiarity with Spanish succession law or from assuming that testamentary freedom operates the same way as in countries such as the United Kingdom, the United States, or Canada

Balancing freedom of testation and local law

Effective succession planning is not about restricting your freedom to decide how your assets are distributed, but about understanding how to exercise that freedom within the Spanish legal framework.

A lawyer specialising in international inheritance can help structure your will in a way that respects the rights of forced heirs while still aligning with your personal and financial objectives. This balance is particularly important for foreign investors who wish to protect specific beneficiaries, optimise the tax position of their estate, and ensure that their will can be fully enforced in Spain.

With the right legal guidance, potential conflicts can be anticipated and avoided, reducing the risk that your heirs will face unnecessary legal disputes at an already sensitive time.

How an inheritance lawyer can help

Maximising tax efficiency

Careful planning makes it possible to optimise the impact of the Spanish inheritance tax and avoid unnecessary costs. By anticipating how tax rules apply to your specific situation, a lawyer can help structure your estate in a way that is both compliant and efficient.

Ensuring compliance with Spanish regulations

Finally, ensuring compliance with Spanish law is essential for a will to be valid and enforceable. A properly drafted Spanish will, aligned with all legal requirements, provides certainty that your wishes can be carried out as intended and that your heirs will not face avoidable legal obstacles during the inheritance process.

Get legal advice before it’s too late

Planning ahead is the most effective way to avoid the most common mistakes with Spanish wills. Many of these issues only become visible when it is too late to correct them, creating unnecessary stress, delays, and financial consequences for those left behind. Taking the time to structure your will properly ensures that your assets in Spain are protected and transferred in line with your intentions.
