The process typically involves these steps:

Choose a name and draft a Partnership Deed: This document outlines the rights, responsibilities, profit-sharing ratio, and other crucial aspects of the partnership.
File Form 1 online: This form is submitted to the Registrar of Firms (ROF) in the state where your firm is located. Many government websites offer online filing options.
Attach required documents: These documents include the Partnership Deed, PAN card and address proof for partners and the firm, proof of business address, and an affidavit verifying the information.
Pay registration fees: The fees vary depending on the state.
