My client (A) is a advertizing agency, dealing in hoardings, bill boards and flex printing. My client entered into a contract with another advertizing firm (B) to print flex sheets and install hoardings for several companies from time to time. The mode of operation was that a purchase order was forwarded to the firm (A) by the firm (B) with a description of the size and design and the firm A used to complete the task and send bills for the same.

Firm B collected orders from several large advertizing agencies based in Delhi and mumbai for companies like Unilever, PnG, Tata, etc. and delegated the same to the firm A.

This carried on for a period of about two years and several bills of the firm were unpaid. The total outstanding amount comes to Rs. 22 lakhs. When the firm A asked the Firm B to pay the unpaid amount, firm B refused the payment.

Now, Firm A has decided to file a suit for recovery against firm B.

Can the other firms based in mumbai and delhi and the companies for whom the task was being performed be made a party to the suit or a legal notice can be sent to them as they are also the benefeciaries to the contract?
