1. Acts performed by the directors in the company’s name and within the powers conferred on them by law bind the company vis-à-vis third parties, notwithstanding any limitations contained in the articles of association or arising from shareholders’ resolutions, even if such limitations have been published.

1 - Os actos praticados pelos administradores, em nome da sociedade e dentro dos poderes que a lei lhes confere, vinculam-na para com terceiros, não obstante as limitações constantes do contrato de sociedade ou resultantes de deliberações dos accionistas, mesmo que tais limitações estejam publicadas.

2. The company may, however, invoke against third parties the limitations on powers arising from its object, if it proves that the third party knew or, in view of the circumstances, could not have been unaware that the act performed did not comply with that clause, and if the company has not in the meantime assumed the act by express or tacit resolution of the shareholders.

2 - A sociedade pode, no entanto, opor a terceiros as limitações de poderes resultantes do seu objecto social, se provar que o terceiro sabia ou não podia ignorar, tendo em conta as circunstâncias, que o acto praticado não respeitava essa cláusula e se, entretanto, a sociedade o não assumiu, por deliberação expressa ou tácita dos accionistas.

3. The knowledge referred to in the preceding paragraph cannot be proved solely by the publication of the articles of association.

3 - O conhecimento referido no número anterior não pode ser provado apenas pela publicidade dada ao contrato de sociedade.

4. Directors bind the company by affixing their signature together with an indication of that capacity.

4 - Os administradores obrigam a sociedade, apondo a sua assinatura, com a indicação dessa qualidade.

What we checked in this article

Third parties are protected despite published limitations; the object-clause exception requires the company to prove the third party's actual or constructive knowledge, publication alone not sufficing.
