Seller wants to cancel the sale of land after getting earnest money
I ("seller") entered into a basic paper agreement for the sale of my plot worth ~ 20lacs (plain paper agreement) to fullfil the sale within 60 days. Buyer paid earnest money of 10,001/- Basis the oral agreement he had to pay the full money via cheque/DD. Later he insisted to take part in black and partly in white, he started to blackmail me, that he can sue me and keep the property on hold if I didn't agree. He also started to abuse me and wants me to sell the property forcefully. Later he has agreed to pay via cheque. As I didn't like the way he dealt, I want to terminate the deal with the seller due to his bad behavior. At any cost I don't want to sell to him. What are the rights of seller and to what extent the Buyer can have a claim on the property over and bove the ernst money paid. Should I send him a legal notice after the expiry of time period of 60 days? What are other remedies to safe guard my interest in the property.
Look forward to your advise and suggestions.
