Registering an act under Article 78-L?

We file registrations at the commercial registry for foreign-owned companies: incorporations, share transfers, manager changes, capital changes, branches, filing of accounts and closures. In English, fixed fees, with the registry fee shown separately.

Unofficial English translation prepared by BCA Portugal for reference. Only the Portuguese text published in the Diário da República has legal force. Editorial notes are ours and are not part of the statute.

Applying the law

Registry work in Portugal, done right the first time

A refused or provisional registration costs weeks. We prepare the documents the registrar expects, file them and follow the application until it is definitive.
