The Share Certificate is an official document that certifies the ownership of shares in a company. Also known as a Stock Certificate, Equity Certificate, Shareholding Certificate, or Certificate of Shares, this document acts as a formal, legal acknowledgment issued by the company or authorized registrar to the shareholder. It represents proof of ownership, the number of shares held, and the rights attached to those shares. Share certificates are widely used for corporate governance, legal disputes, due diligence, investment confirmation, and compliance procedures.
