Membership in a company can take several forms. Members and shareholders of a company collectively constitute the company as a corporate entity. A person can become a member through subscription, application and registration, beneficial ownership, or by holding qualification shares. Membership can cease through the act of parties such as transferring shares or if they are forfeited, or by operation of law like insolvency or death. Members have various rights like statutory, documentary and legal rights, as well as rights to company assets, and responsibilities that depend on the type of company like one with limited or unlimited liability. A company is required to maintain a register of members and an index of members if it has more than 50.
