Rate of interest, in Case of Cancellation of land agreement

Hello Sir,

        Myself Sateesh Kumar, for purchasing a site in housing society, Bangalore, The land owner(who is having land in housing society ) and me made an an agreement. We wrote in the agreement in 200 Rs Stamp paper on Apr'2008 as - the value of the land is 8 lakhs and I gave 7 lakhs rupees as advance to land owner and within the period of 3 months the land owner show the land and register the land in my name then i need to give remaining 1 lakh rupees to land owner.

        But till now (after 24 months) the land owner is not showed his land and not registered in my name. Whenever I ask with land owner regarding land details and registration, he is saying that soon i will show your land and I will register in your name.

        I need to know the validity of 200rs stamp paper (even though we made agreement for registration within three months).

        Without showing land details and registration, I am not interested on this land. The agreement for 3 months only but now the agreement date is crossed 21 months. Could you please advice me, how can I proceed with this.

        Regarding this land registration, I asked to Land Owner that register the place in my name or return my money with interest.

The Land owner agreed to give me money back with interest.

Please advise me how much rate of interest I can ask with land owner with my money 7 lakh rupees.

Regarding this, if I proceed to consumer court, then what rate of interest I will get from land owner.

Please advise me on this.

Thanks & Regards

Sateesh
