A director signature is the signature of a company’s director. It is required on certain documents, such as resolutions and share certificates.
A manager signature is the signature of a company’s manager. It is required on certain documents, such as contracts and invoices.
A managing director signature is the signature of a
company’s managing director. It is required on certain documents, such as financial statements and reports.A common seal is a more formal way of authenticating documents than a director or manager signature. It is also more difficult to forge.
