Q.1.Whether sale agreement is still valid or its valid upto six months from the date of registration.
Ans: Validity as agreed by you both parties is within four months from the date of agreement which has already expired. However, it can further be extended mutually.
Q.2.Should I issue a legal notice to purchaser either to pay the remaining amount immediately or cancel the sale agreement.
Ans: You can issue legal notice to the purchaser to pay the remaining amount or cancel the sale agreement. Had the following clause been added, you would have faced no problem:
"In case purchaser failed to pay balance amount within 4 months from the date of agreement, the payment of 1 lakh will be forfeited".
Q.3.There is no penalty clause mentioned in the agreement. Shall I increase the price of sale consideration if the purchaser asks some more time.
Ans.: Yes, you can. However, kindly see the genuineness of the purchaser. Go to the bank from where the purchaser is taking the loan, enquire whether he has applied for the loan or not and how much time it would take to release the loan. If possible, you can go alongwith the purchaser also. But it it seems that he is unnecessarily dragging the matter, issue legal notice and cancel the sale agreement.
I hope this would suffice the purpose.
Could you kindly clarify.
