Power of Attorney in Spain: Investing without appearing before the notary yourself

A power of attorney in Spain, the poder notarial, allows someone else to sign on your behalf before a Spanish notary. For an investor participating in a Spanish real estate project from the Netherlands, this is often the most practical route: you do not need to travel to Spain for every deed. At the same time, a power of attorney is not just a formality. If it is drafted too broadly, you give away more authority than necessary, and if it is drafted too narrowly, you may find yourself empty-handed at the notary. This article explains the different types, where to have a power of attorney drawn up, and what to look out for regarding its content.

What a power of attorney in Spain entails legally

For actions that require a notarial deed in Spain, a private power of attorney is insufficient. The notary will only accept a power of attorney that has been executed as a notarial deed itself or drawn up by a consular official. The person acting on your behalf is called the apoderado. They must act within the limits of the text and cannot exceed them. Consequently, that text is the sole determinant of what can be done on your behalf.

General or special power of attorney

Spanish law distinguishes between two main forms. The difference lies in the scope, and therefore in the risk you incur. For an investor, the choice is rarely complicated, but it must be made consciously. Below are the two forms compared.

Poder general

A general power of attorney gives the authorized representative broad powers, often including buying, selling, and encumbering real estate, as well as managing bank accounts. This is practical for those who do business in Spain long-term and have a single trusted representative. For an investor in a specific, defined project, it is usually too much. A general power of attorney remains valid until it is revoked, even if the project has long been completed. It is precisely this that makes it risky.

Poder especial

A special power of attorney is limited to one or more specific actions. Think of signing a specific deed for a capital increase or accepting a mortgage right on a particular property. The more concrete the description—including cadastral data, amounts, and parties—the smaller the room for abuse or misunderstanding. For almost every investment action, this is the correct form. Ensure the text is drafted so that it expires as soon as the action has been completed.

Where to have a power of attorney for Spain drawn up

There are three routes, each with its own formalities. The choice depends on where you are, how much time you have, and whether the deed needs to be drawn up in Spanish. In all cases, the power of attorney is only usable once it is in the form accepted by the Spanish notary. Therefore, ask that notary about their requirements in advance.

With a Dutch notary

A Dutch notary can draw up a power of attorney for use in Spain, preferably in a bilingual deed in Dutch and Spanish. If the deed is only in Dutch, a sworn translation into Spanish is required. Subsequently, the court will provide the notary's signature with an apostille, which allows the deed to be recognized in Spain. This route is the most practical for most investors. Expect a turnaround time of a few days to two weeks.

At the Spanish consulate

The Spanish Consulate General in Amsterdam can draw up a power of attorney directly in the Spanish format. An apostille and a translation are then unnecessary because the deed is already a Spanish document. The consulate works by appointment, and the waiting time for an appointment can be long. This route is attractive if the Spanish notary provides a text in a specific format. You then sign exactly what is expected in Spain.

With a Spanish notary

If you happen to be in Spain, you can have the power of attorney drawn up there by a notary. This is simple and fast. A Spanish notary is required to ensure that you understand the content and will engage an interpreter if your command of Spanish is insufficient. Preferably, combine this with other actions so that one trip suffices. For subsequent actions, the power of attorney can then be used from the Netherlands.

Which actions an investor has performed via a power of attorney

Not every step in an investment requires your presence or a power of attorney. For actions that do require a notarial deed, a power of attorney is the standard solution. Which actions these are depends on your specific position. How the project structure works is described in the article on investing via a Spanish S.L.. Common actions include the following.

• Applying for your NIE, the Spanish tax identification number, if you are not going to the consulate or a Spanish police station yourself
• Signing a deed for a capital increase or the transfer of shares in an S.L.
• Accepting a mortgage right as security for a loan
• Signing an investment agreement in notarial form
• Canceling a mortgage right after repayment

For the establishment of a mortgage, the power of attorney is one of the documents the notary checks before the deed can be executed. You can read about the step-by-step process of this establishment in the article on mortgage security in Spain. Which provisions in the agreement itself carry significant weight is detailed in the article on the investment agreement. Opening a Spanish bank account via an authorized representative is handled differently by each bank. Many banks require personal identification as part of their client due diligence.

Choosing your authorized representative

The most important choice in a power of attorney is not the text, but the person. An authorized representative acts on your behalf, and whatever they sign within their authority binds you. Therefore, appoint someone who looks after your interests and not those of the counterparty. Your own Spanish lawyer or gestor, whom you select and pay yourself, is the standard choice. Never let the project developer or one of their employees sign on your behalf on the other side of the same transaction, even if it is offered as a practical solution.

This independence aligns with the broader due diligence you conduct before making a commitment. If someone is signing on behalf of the project company based on a power of attorney, request that power of attorney and check its scope. Which other documents you should request is covered in the article on due diligence for a Spanish real estate project. A power of attorney is a document like any other and deserves the same level of scrutiny. Anyone who fails to do so is relying on a signature without knowing what it stands for.

Power of attorney from a holding company

If you are participating through a Dutch private limited company (B.V.), it is not you but the company that grants the power of attorney. The director signs on behalf of the company, and the notary verifies their authority to do so. This usually requires a recent extract from the Commercial Register, provided with an apostille and a sworn translation. Please note that the Spanish notary may sometimes also request to see the articles of association. Other considerations regarding participation through a company are outlined in the article on real estate through your holding company.

Revocation and termination

A power of attorney does not automatically end when the project is completed, unless the text specifies otherwise. You can revoke a power of attorney via a notarial deed of revocation, the revocación. Afterward, notify the authorized representative and the relevant Spanish notary so that the old power of attorney is not used inadvertently. In principle, a power of attorney also ends upon the death of the principal. You can read about what happens to a Spanish position upon death in the article on inheritance tax in Spain.

Common mistakes

Most delays at the notary are related to the power of attorney. A missing apostille or wording that is just a bit too narrow can mean a new appointment and sometimes weeks of delay. This affects the project schedule and, indirectly, your position. These are the most common mistakes in practice.

• Granting a general power of attorney for an action for which a specific power of attorney suffices
• Forgetting the apostille or the sworn translation, causing the Spanish notary to refuse the deed
• Not having the text reviewed in advance by the Spanish notary who will be executing the deed
• Appointing an attorney-in-fact who also acts for the counterparty
• Failing to revoke a power of attorney after the project has been completed

Frequently asked questions

Below are the most frequently asked questions about using a power of attorney for a Spanish project.

How long is a power of attorney valid in Spain?

A power of attorney has no legal expiration date and remains valid until it is revoked, unless the text contains an end date or a limitation to a single act. In practice, some notaries and banks are less willing to accept an older power of attorney. For a specific power of attorney, therefore, include a provision that it terminates as soon as the act has been performed. This prevents discussion later on.

What does a power of attorney for Spain cost?

Costs consist of the notary's fee, the apostille, and possibly a sworn translation. As an indication, this amounts to a few hundred euros in total in the Netherlands, depending on the notary and the length of the text. Costs are generally lower via the consulate, but the waiting time is longer. Request a quote in advance, as fees vary per office.

Can I sign a power of attorney digitally?

For use with a Spanish notary, a physically executed deed with an apostille is generally required. While Spain does have forms of digital notarial services, these are primarily aimed at Spanish residents and specific acts. For an investment, assume that you will need to sign the power of attorney in person. If in doubt, ask the Spanish notary which form they accept.

Does the authorized representative also need a NIE?

Yes, anyone signing a notarial deed in Spain must identify themselves, which requires a NIE or a Spanish identity document. For a Spanish lawyer or gestor, this is standard procedure. You will also need your own NIE for the transaction itself. Arrange both well in advance, as applying for a NIE takes several weeks.

Does a power of attorney have tax implications?

The power of attorney itself does not, but the action performed with it does. Whether you participate as a partner or as a lender determines how your income is treated in Spain and the Netherlands. For a fixed fee, this is detailed in the article on interest income from Spain. Always have the tax aspects reviewed separately.

Next steps

A power of attorney in Spain is a practical tool, provided it is limited, verifiable, and arranged in a timely manner. Preferably choose a specific power of attorney, have the text coordinated in advance with the Spanish notary, and appoint an attorney-in-fact who exclusively represents your interests. Have the power of attorney and the underlying transaction reviewed by your own advisor with knowledge of Spanish law.
