We filed a specific performance suit against the seller after two months of expiry of the sale deed since the seller did not cooperate to sell the property to us(sale agreement(UN-registered) was on a Rs 50 stamp paper valid for two years by paying 1/6 th the property value). Now the seller tries to sell the property to someone else(again entered into an agreement with some one after taking a advance). Can we prevent this sale being executed legally? Please help. We are living in the 1st floor of the property which is under dispute and the seller lives in ground floor.
