QUALIFIED ELECTRONIC SIGNATURE · TERRASSA

Online digital signature certification in Terrassa

Q: Does the notary handling my case know Catalan civil law?

Yes. Our notaries are licensed in Spain and regularly work with the Catalan Civil Code, which is decisive in matters of inheritance, marriage contracts, and matrimonial property regimes. If your case falls under Catalan law, the document will be drafted accordingly.

Q: Can I sign the document in Catalan?

Yes, the deed can be executed in Catalan, Spanish, or both languages. Just let us know when booking your appointment and we'll prepare it accordingly.

Q: Will it be recorded at the Terrassa Land Registry?

Yes. The electronic deed is submitted electronically to the competent Registry based on the property's location, whether in Terrassa or any other municipality.

Q: What if my matter involves a Catalan inheritance?

Book IV of the Catalan Civil Code applies, with its own rules on the forced heirship share (one quarter, not two-thirds) and the possibility of succession agreements. We'll explain exactly how this affects your case before you sign anything.

Q: What is the difference between certifying my signature and converting the document into a public deed?

Signature certification confirms that the signature is yours, while the document remains private. Converting it into a public deed turns the entire content into a notarial instrument, with much greater legal force. We advise you on what your case actually requires, which is often the first and more affordable option.

Yes, for the qualified electronic signature. If you don't have one, we'll help you obtain it before the appointment at no additional management cost.

Yes, absolutely. According to Law 6/2020 and the eIDAS Regulation, digital signature authentication performed by a notary has full legal validity throughout Spain and the European Union.The electronic notarial certificate has the same legal effects as a document signed in person before a notary.

That explains why online notarial procedures have caught on here: it's not a matter of convenience, it's that half of these transactions happen while you're somewhere else entirely.

Digital Signature Certification: what they are and what they are for

Notarial signature certification verifies the authenticity of your signature on a private document: a contract, a guarantee, an authorization, or a document that must take effect in another country. With a qualified electronic signature, the entire process takes place online, and the result carries evidentiary value that a scanned signature simply cannot match.

Online digital signature authentication is a notarial act that certifies that an electronic signature truly belongs to the person who claims to have made it. This service allows you to sign important documents from anywhere, with the same legal validity as if you attended the notary office in person.

The notary verifies your identity through advanced electronic systems and issues an authentication certificate that provides public attestation that the signature is genuine. This notarial backing transforms a simple electronic signature into solid legal proof with full evidentiary validity.

Thanks to the eIDAS Regulation and Law 6/2020 on electronic trust services, this procedure has full legal recognition in Spain and throughout the European Union. You can use this service for contracts, powers of attorney, authorizations, and other private documents.

What changes if you are in Terrassa

Particularities of Catalonia that affect your procedure, beyond the name of the city

Catalan civil law

Catalonia has its own civil law, which directly affects inheritance, marriage contracts, and matrimonial property regimes. This isn't a minor detail—it changes the substance of the document, not just its form.

Separation of property as the default regime

In Catalonia, the default legal regime is separation of property, not community property. Many couples in Terrassa assume the opposite and only discover the error when buying property or handling an inheritance.

Succession agreements

The Catalan Civil Code allows succession agreements (heretaments), which are prohibited under common Spanish law. This is a family and business planning tool that is available here.

Notarial College of Catalonia

Our notaries are licensed in Spain and are well-versed in Catalan legal specifics. The document is fully valid in Terrassa and throughout Catalonia.

APPLICABLE REGULATIONS: Law 10/2008, Catalan Civil Code, Book IV (inheritance) Law 25/2010, Book II (persons and family) Law 11/2023 (notarial video call)
