What the Act actually requires
Sections 58 and 59 of the Partnership Act, 1932 make registration with the state Registrar of Firms voluntary — a Mumbai firm registers with the Maharashtra RoF. The firm exists from the partnership deed itself; registration merely records it. That is why thousands of firms run unregistered for years without noticing anything wrong — until a dispute arrives.
Section 69: the price of staying unregistered
An unregistered firm (or a partner in one) cannot file a suit to enforce a contractual right — recovering money from a defaulting customer included. Partners cannot sue one another or the firm over deed rights. Claims of set-off above ₹100 are barred. The disability is one-directional: third parties can sue the firm freely. In effect, every credit sale an unregistered firm makes is legally unenforceable by it.
The practical course
Register at formation — the cost and effort are minor against the section 69 risk, and registration can also be done later (courts have allowed suits after subsequent registration, but you lose time exactly when you need speed). Execute a properly stamped deed, obtain PAN, then decide whether the business belongs in a firm at all — for two or more owners building anything long-lived, an LLP or company often serves better.
