An authorized signatory is different from a director.
An authorized signatory is defined as someone who has been authorized to sign documents and has notified the trustee that they've been given the power to do so. A representative or officer is normally given the power to sign the organization to an agreement that's binding. This is also known as a signing officer. The legal power is given by someone in authority to positions that are organizational, such as manager, to make them agents of that organization for specific or general purposes.
The persons who are in charge of the management of the affairs of a company are termed as directors. They are collectively known as Board of Directors or the Board. The directors are the brain of a company. They occupy a pivotal position in the structure of the company. Directors take the decision regarding the management of a company collectively in their meetings known as Board Meetings or at the meetings of their committees constituted for certain specific purposes. Section 2 (10) of the Companies Act, 2013 defined that “Board of Directors” or “Board”, in relation to a company, means the collective body of the directors of the company.
From the definition its is plenty clear that while a director is someone who has authority and manages the affairs of company, an authorized signature is the one authorized by directors or higher management to take decisions on their behalf. Hence, you don’t need to worry as a director need not be an authorized signatory.
