Me and my partner run a small firm, Tours & Travel at Delhi. 3year we do good business, but starting of first year, i shld not take so much of bank dlts and about the payments and also the profits, But after 2nd years i use to check everything when our business goes smooth and we starts getting good business. but he is not suppose to share any monthly sales reports, even how much payments comes or transfers outside. Like this its been become 3rd year, So now on 2019 March, i told him like this i not continious as partner so please close the firm or else give all dtls, Net banking passwords and daily sales reports or CC to me whatever the leads you picked up. after lots of arguments he discussed with his father, he given me password of bank. then i come to know he done 3Lacs of FD without my knowledge and even he not bother to tel me. I don't know how come with my sign in fd form, fd will done, and when i checked he said you can call bank manager he will make the fd for you anytime. without the sign.Even after new GST passed, he purchase GST portal, Tally single operate software. which also i not aware. Like this lots of small small things are there. He deals unlawful outside business, which i come to know from outsider which vendors. Lots of things to share but i cant here. I just want to close and surrender our Firm of partnership, GST to closed and pay balance amount to few vendors, but i cant pay bcos with his signature FD with not break and we not get amount in bank. Last November 2019 am keep calling and requesting him, please do needful and close the firm and surrender all. but he not response me. One more thing like to share that in between month of Nov-19, he empty our office, and take all the stuff and office clear the office with my knowledge, then office owner call me and told me that sir he taken all the office stuff and i taken written from him, and also not stoped bcos he also the partner of this firm so how come i stop him, when i question him for this. Lots of friends and my office neighbours told to go for FIR but i can't go becouse of good relation be keep further. But he not maintain that also. So please kindly advise what to do, he should come to close the firm, surrender all the firm GST/Tally/Banking. Also can i withdrawal the FD from bank and pay to vendors. Or any law i can stop the GST penalty. Please advise..am very helpless and be as middle class family, he should taking my opportunity.. Should i go for send legal notice, so he close the firm
