Olá amigos,

Alguém poderia confimar se "common Seal" é realmente "selo comum"?

Veja a definição:
Common Seal: A company is an artificial person and does not have a physical presence. Therefore, it acts through its Board of Directors for carrying out its activities and entering into various agreements. Such contracts must be under the seal of the company. The common seal is the official signature of the company. The name of the company must be engraved on the common seal. Any document not bearing the seal of the company may not be accepted as authentic and may not have any legal force.

Com certeza não é uma "foca vulgar" :-)

Obrigado
