Registrations and Document Authentication

Support in registration, authentication, and document formalisation. Preparation, verification, and formalisation of documents.

Overview

Registrations and authentications formalize facts, rights, and documents. The appropriate action depends on the objective, the parties involved, the powers of representation, and the original documents.

When we can help

  • Recognition, authentication, and certification of documents
  • Civil, property, commercial and vehicle registrations
  • Powers of attorney, translations, and foreign documents

Documents to gather

  • Explain the objective and the country where the document will be used
  • Confirm originals, identification, and powers of representation
  • Check if an apostille, translation, or additional formality is required.

Frequently Asked Questions

Are document authentication and signature certification the same thing?

No. Acts have different scope and requirements and must correspond to the intended use.

Does a Portuguese document automatically have validity abroad?

Not always. The destination country may require an apostille, legalisation, or certified translation.
