Consumer Redressal

I had purchased flat in mumbai in year july 2012,agreement got registered stampduty paid but when i presented the papers to society for mebership transfer they refused saying that there is a MOU signed by the seller with another person but this MOU date of 2 months was over in month of Jan 2012. When the society came to know abt this they infromed the MOU holder who is also the chairman of society that the flat is sold so he did not transfer the flat and instead he filed a suit in Mumbai high court and got the status quo. Now since i am working abroad,i travel only once e ayear the flat is in my possesion but the case is ging on. Please let me know any solution since its not my fault and i cannot even put on rent.
