About the service

What is the Legal Advice for Startups in Spain?

The journey of a startup, from a simple idea to a market leader, is a high-stakes race. Legal advice for startups in Spain is not a bureaucratic hurdle; it is your strategic shield and your launching pad.

We understand that you move fast, and your legal support must move faster.

Everything starts with the foundation. The most critical document is the Shareholders’ Agreement (Pacto de Socios). It defines the rules of the game between founders, protecting everyone’s interests before you even start.

Next, we protect your most valuable asset: your idea. We manage the registration of your intellectual property, from securing your trademark to protecting your software’s source code through copyright, ensuring no one can copy what makes you unique.

In today’s digital world, data protection (GDPR) is not an option. We implement the necessary legal texts, like Privacy Policies and Terms & Conditions, to ensure your website or app is fully compliant from its launch, avoiding massive potential fines.

Attracting and retaining the best talent is key. We help you design and implement Employee Stock Option Plans (ESOPs), a powerful tool to incentivize your key team members when cash is tight.

From drafting your first client contracts to scaling internationally, we are not just lawyers. We are your external legal department, built for the speed and demands of the startup ecosystem.

 Trustindex verifies that the original source of the review is Google. I had an amazing experience working with Dario and his team throughout my visa process. They made everything completely stress-free and were incredibly helpful every step of the way. Dario speaks excellent English, which made communication easy and comfortable, and he was always responsive, patient, and clear in explaining everything. He and his colleagues handled every detail with care, efficiency, and in a very timely manner, which gave me a lot of confidence and truly made my life so much easier throughout the entire process. By far the best lawyer I’ve worked with in Barcelona. I couldn’t have asked for a better experience and would highly recommend Dario and his team to anyone needing help with visas or immigration.

 Trustindex verifies that the original source of the review is Google. A friend recommended Illay Legal  to help obtain my permanent residency in Spain. Exceptional service! Marc explained every part of the process clearly and precisely. Once I provided all the necessary details, the team did all the work: pre-completed the necessary paperwork, helped retrieve padron and digital tax certificate, secured appointments in my preferred neighbourhood and checked in with me before and after both appointments. I subsequently switched both my tax and business accountancy contracts to Marc's firm and have enjoyed the same very high level of service. Communication via email and WhatsApp, and extremely responsive to answering any small or large questions/concerns. A huge endorsement to the whole team - I would highly reccomend. Regards Ismail

 Trustindex verifies that the original source of the review is Google. Lawyers I truly trust and genuinely enjoy working with. Huge thanks to Marc and Soundous for guiding me through a very stressful documentation process over the past few years. Together we managed to resolve a complicated situation I ended up in because of a bureaucratic issue with my previous paperwork. They have well-organized processes and a lot of experience with different kinds of cases — even the tricky ones. Whenever I was stressed or freaking out, they were always there to reassure and support me. That human approach means a lot. With them, you are in very good hands 💚

FAQ

Frequently asked questions about the Legal Advice for Startups in Spain

Why do I need a shareholders' agreement if we are all friends?

A shareholders’ agreement is like a prenuptial agreement for business. It protects your friendship and the company by setting clear rules for complex future scenarios like a founder leaving, a disagreement, or a buyout offer.

How can I protect my app's name and software?

You protect the name and logo by registering it as a trademark. The software code is automatically protected by copyright, but we can help you with strategies like registering it with a notary or the IP registry to create stronger proof of ownership.

What is a "term sheet" and is it binding?

A Term Sheet is a document that outlines the main terms of an investment. It is generally non-binding, but it serves as the foundational guide for drafting the final, binding investment contracts.

Do I really need to comply with GDPR from day one?

Yes, absolutely. If your startup processes any personal data from users in the EU (even just an email address), compliance is mandatory from the start. The fines for non-compliance are extremely high and can be devastating for a new business.

What is an ESOP and why is it useful for a startup?

An ESOP (Employee Stock Option Plan) is a system to grant employees the right to buy company shares at a fixed price in the future. It’s a powerful tool to attract and retain top talent when you can’t compete with large salaries.

Guiding you in every step to your bright future.
