Anybody got solution to this issue?

You have not mentioned details about the lease deed.

First - is the lease deed stamped properly and registered? If it is not, then it can be questioned in the court and can be proved to be invalid if other conditions are also in your favour e.g. appropriate consideration was not paid, etc.

If the lease deed was registered, then you cannot claim that the person had any "evil intentions" or that he took your signatures without your consent. The office of the registrar require witnesses and takes your photographs, etc during registration.

In any case, if the consideration was not commensurate to the rights given, you may be able to win your case. However, if the amount of consideration is appropriate, then you cannot hide behind your ignorance or that you feel cheated after surrendering your property on lease.

Thank you for the reply!

Yes, the deed is a registered one. But, actually the property was mortgaged in favour of a bank. And, later this lease agreement occurred and though the property was already mortgaged, the registrar didn't register it at that time. He just marked it as pending. But, later the party managed him and converted pending into absolute. Also, the amount wan't decided that time. The party later wrote with a pen the amount as ten lakhs. Where as the property is worth crores. So, how can anybody give a property worth crores on lease for sake of ten lakhs? I need to break down this deed to save my property. Please respond to my reply.

Thank you!
