Power of Attorney to Sign Checks, Promissory Notes and Bills of Exchange

Authorizes the signing of negotiable instruments with the level of control your treasury department needs.

Negotiable instruments carry executory force: a promissory note signed without proper controls can end up being enforced against the company with no prior opportunity to contest it on the merits. That is why this power of attorney demands more precision than any other regarding maximum amount, type of instrument, and signature regime.

Frequently asked questions

Does this power allow signing checks without amount limit?

It depends entirely on your decision. You can grant an unlimited power or establish specific amount restrictions, either per individual operation or cumulative limit in a given period.

We recommend establishing limits when delegating to employees or third parties, reserving larger operations for your personal signature. This offers operational flexibility while maintaining control over significant transactions.

Can the agent also endorse or collect credit instruments?+

Yes, as long as those powers are expressly included in the notarial power. You can authorize only signing, or expand the powers to include endorsement, collection presentation, acceptance of instruments, or even protesting non-payments.

During document drafting, we will specify exactly what operations the agent can perform according to your operational needs.

What happens if a banking entity rejects the power?+

A properly drafted notarial power issued by a licensed notary has full legal validity throughout Spain. Banking entities are obligated to recognize it in accordance with current regulations.

In exceptional cases where an entity requires specific formats, we can handle additional legalizations or adaptations. Our notaries guarantee that the document meets all legal requirements for universal acceptance.

Can the power be revoked at any time?+

Yes, absolutely. As principal, you can revoke the power at any time through a notarial deed of revocation, which we also handle online.

The revocation takes immediate effect once formalized. We recommend simultaneously notifying banking entities and the agent to prevent improper use after cancellation.

Who is legally responsible for checks signed by the agent?+

You, as principal, are legally responsible for all acts performed by the agent within the limits of the power granted. Instruments signed by the agent have the same legal effect as if you had signed them personally.

That is why it is essential to grant this power only to people of maximum trust and establish clear action limits. The agent acts on your behalf but patrimonial responsibility falls on you.

Do I need to be in Spain to grant this power?+

No. Our service is specifically designed for people who cannot physically travel to a notary office. Through secure video conference and digital identification systems, you can grant the power from anywhere in the world.

You only need an internet connection, a device with a camera, and your digital certificate or valid electronic identification method.

How long does it take for the notarial power to be ready?+

The complete process is usually done in less than 24 business hours. Once we receive your request and documentation, our notaries draft the customized power and we coordinate the signing video conference according to your availability.

After signing, you immediately receive the document in digital format with complete legal validity. If you need additional copies or specific legalizations, we can handle them in the same timeframe.

Can I grant this power to several people simultaneously?+

Yes, you can designate multiple agents in the same power or through separate powers. You can establish that they act jointly (all must sign) or individually (anyone can sign).

It is also possible to grant different levels of powers to different agents: for example, one with a €5,000 limit and another with a €20,000 limit, adapting to your organization's responsibility structure.

Does this power work for general bank account operations?+

This power is specifically designed for signing checks and credit instruments (promissory notes, bills). If you need to authorize broader banking operations such as transfers, account openings, or direct debits, you should consider a power for general banking operations.

We can advise you on which type of power best suits your specific needs, or combine powers in a single comprehensive notarial document.

What is the difference between this power and a simple bank authorization?+

A simple bank authorization is only valid at the specific entity where it is formalized and generally with limited scope. A notarial power for signing checks and credit instruments has universal legal validity before any entity, court, or third party.

Additionally, the notarial power allows broader actions: endorsing instruments, presenting them for collection at different banks, protesting, or managing operations with third parties. It offers greater flexibility and legal security for complex commercial operations.

Why is this more sensitive than a standard banking power of attorney?+
Because a promissory note or bill of exchange is an executory instrument: the holder can go straight to enforcement proceedings. Improper use cannot be conveniently disputed afterward; enforcement happens first, and any dispute is subject to significant limitations.
Can I require two signatures?+
Yes, and it is the most effective safeguard. It is usually structured in tiers: individual signature up to a certain amount and joint signature above it.
Does it include endorsing instruments?+
Only if expressly stated. This is essential if you will be operating discount facilities.
Does the bank need to know the limits?+
Yes. The power of attorney produces legal effects, but operational control is applied by the bank when it registers the signatures and their conditions. It must be formally communicated to them.
What should I do if a checkbook is lost or the attorney-in-fact's authority ends?+
Immediate revocation, notification to the attorney-in-fact, and urgent communication to all banks. In matters involving negotiable instruments, every day counts.
Do documents signed online have the same validity as those signed in person?+
Exactly the same. Law 11/2023 recognises the full legal validity of notarial documents executed by video call with a qualified electronic signature before a registered notary.
Do I need a digital certificate?+
Yes, to sign electronically you need a digital certificate or an electronic DNI. If you do not have one, we help you obtain it quickly before your appointment, with no additional handling fee.
Can I do it from abroad?+
Yes, the notarial video call works from any country. You only need a stable connection, your valid identity document and a digital certificate.
How much does this service cost?+
The quote includes the official notarial fees set by the Notarial Association plus our handling, fixed before you start and with no hidden costs. Request it with no obligation via WhatsApp or the form.
What if I have questions during the process?+
Our team supports you from start to finish via WhatsApp, phone or email, and the notary answers all your legal questions before signing.
