Since the matter is sub-judice, you can approach the court to allow the transactions subject to the outcome and the buyer must be willing to take that risk as well. Then you can go ahead as well without any fear. For further queries you can contact me on firstname.lastname@example.org
Since the property is subjudice the only way to sell it is to make the buyer agree to the outcome of the case pending. More befitting way to sell the property is to make an application before the court in which the matter is pending to allow you to sell the property. The court is convinced will take security and undertaking from the new buyer and might allow the sell.
