A partnership is easy to form as no cumbersome legal formalities are involved. Its registration is also not essential. However, if the firm is not registered, it will be deprived of certain legal benefits. The Registrar of Firms is responsible for registering partnership firms. The minimum number of partners must be two, while the maximum number can be 20. A partnership is formed by an agreement, which may be either written or oral. When the written agreement is duly stamped and registered, it is known as "Partnership Deed". Ordinarily, the rights, duties and liabilities of partners are laid down in the deed. But in the case where the deed does not specify the rights and obligations, the provisions of The Indian Partnership Act, 1932 will apply.
