I had added this post earlier,but adding a few more details.
I have purchased a flat in Andheri. I have made the full payment by Cheque & Demand draft.
I have taken possession of the flat & am staying here since a few months now.The original flat papers were destroyed in the floods.The previous owner had given a irrevokable power of Atorney in the name of his son, and the entire transaction was conducted by his son.

Now the previous owner has come to me saying that his sons have played mischief & forged his signature to disposed off the property.

I have an aggrement which is registered.I also have an indemnity bond given by both the sons.

Can this person put a suit on me ? After paying the full value for the property do i have to run to court for no fault of mine?I have all the necessary papers that makes me the rightfull owner.
Please advice
