I am owner of flat but not a member of society

I am owner of a flat in a CHS in Thane City but I am not a member as of today as Society is trying to recover some dues from my previous owner and my application is not been accepted or even considered in the mean time. I wish to know my rights as a flat owner in the society. Background- there is a dispute between society member, committee and the previous owner regarding some fines, case is still ongoing since decemeber. I wanted to get a society noc for Share certificate - so I can request the bank to give me the share certificate to update my name in the certificate. My request is ignored/put on hold in the meantime the above dispute is resolved. also, I am not been levied any parking charges for my vehicle, stating that I am not registered member yet so I cannot apply for parking space thus no parking charges in monthly maintenance bill, none of my other requests are even considered on the similar lines. the membership still lies under the previous owner's name so only he can apply for any requests. The backside of my flat (society premises) is been treated as dumping ground at the moment whereas the rest of the society is super clean. I have to specifically ask the sweeper to clean the area. My request is ignore time and again. How can I proceed and what are the donts and dos I should follow.
