My NRI brother signed an agreement of sale with a guy from Kolkata and made my mother the witness. This was done on Rs 20 stamp paper and in our house on 16th April 2013 but was not registered. The guy could not get the money ready and my brother had arrived for a week in July just for the sale. So my brother sold the flat to another buyer who had ready money, after the expiry of 3 months. Now the first buyer is sending lawyers letters to my mother asking my brother to return the deposit of Rs 1 lakh.
Q1) Can the guy do anything to harm my mother? His lawyer has threatened my mother with police arrest, fraud and criminal case.
Q2) We were told that the guy can bring a case for upto 3 years. In that case when does his 3 years expire? Is it 16th April 2016?
Please advise, my mother has become ill with stress.
