Cheque bounce gst dilemma firm

I had a Proprietorship firm in MP with which I was doing import export business since 2015 and with this firm I gave material imported goods on credit to a firm based in Mumbai in 2015 during VAT/CST time. Due to losses in business I did not continue my business after 1 July 2017 and did not get GST registration and my firm was shut down but bank accounts of my firm are active. The Mumbai firm gave me a Cheque of the payment that was on credit of Rs 2 lakhs in 2018. But now when I am trying to clear the cheque I got information from the bank that the Mumbai firm doesn't have sufficient balance in their bank account. Now I am planning to send them legal notice and file a cheque bounce case under IPC 138. Cheque I haven't bounced yet because I am under the dilemma if I should get my GST registration done with the GST authorities for my proprietorship firm in MP under the same name or I don't need to do GST registration done to file a case 138 against Mumbai firm because at present after GST my proprietorship firm got non existent as I did not get transferred my TIN number to GST on 1 July 2017. My question is : Do I need to get GST registration done for my firm under same old name and address to file case under IPC 138 against the Mumbai firm for the case to hold in law at the sessions court in MP.
