1. Registration by transcription is void:

1 - O registo por transcrição é nulo:

#

a) Where it is false or has been made on the basis of false instruments;

a) Quando for falso ou tiver sido feito com base em títulos falsos;

#

b) Where it has been made on the basis of instruments insufficient to constitute legal proof of the registered fact;

b) Quando tiver sido feito com base em títulos insuficientes para a prova legal do facto registado;

#

c) Where it suffers from omissions or inaccuracies that give rise to uncertainty as to the parties to, or the subject matter of, the legal relationship to which the registered fact relates;

c) Quando enfermar de omissões ou inexactidões de que resulte incerteza acerca dos sujeitos ou do objecto da relação jurídica a que o facto registado se refere;

#

d) Where it has been signed by a person lacking functional competence, save as provided in Article 369(2) of the Civil Code, and cannot be confirmed;

d) Quando tiver sido assinado por pessoa sem competência funcional, salvo o disposto no n.º 2 do artigo 369.º do Código Civil, e não possa ser confirmado;

#

e) Where it has been drawn up without prior filing.

e) Quando tiver sido lavrado sem apresentação prévia.

#

2. Void registrations may only be rectified in the cases provided for by law, if the action for a declaration of nullity has not been registered.

2 - Os registos nulos só podem ser rectificados nos casos previstos na lei, se não estiver registada a acção de declaração de nulidade.

#

3. The nullity of a registration may, however, only be invoked after it has been declared by a judicial decision that has become res judicata.

3 - A nulidade do registo só pode, porém, ser invocada depois de declarada por decisão judicial com trânsito em julgado.

#

4. A declaration of nullity of a registration does not prejudice rights acquired for consideration by a third party in good faith, if the registration of the corresponding facts predates the registration of the action for nullity.

4 - A declaração de nulidade do registo não prejudica os direitos adquiridos a título oneroso por terceiro de boa fé, se o registo dos correspondentes factos for anterior ao registo da acção de nulidade.

What we checked in this article

The five grounds of nullity of registration by transcription, the bar on rectification once the nullity action is registered, the need for a final court decision, and protection of good-faith third parties acquiring for consideration are retained.

Registering an act under Article 22?

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.
