Terms of Contract 5item Two parties reached an agreement concerning a sale whereby the purchaser paid a down payment to the vendor. About it they prepared a document and stipulated therein that in the event of not completing the deal, the defaulting party should pay a certain amount to the party who kept his part of the deal. Could this very document be considered a sale document? In other words, is the mere agreement between the two parties and their will to complete the deal sufficient for the materialization of the sale in such a way that each party is allowed to demand the other to observe the mentioned condition? Members of a family agreed between themselves on the sale of, or reached a settlement about, some property and got the deal written and signed. However, they neither registered the sale with the competent authorities, nor was the particular formula uttered by a cleric. Is such transaction valid from both shar‘ī and legal aspects? Is preparing an unofficial sale contract sufficient for the materialization of sale between the vendor and purchaser? And is the intention of both the parties to carry out the contract sufficient to make the deal a reality and, therefore, does it bind the vendor to prepare the official sale document and transfer the goods to the purchaser? Is it permissible to buy property without officially registering its deed with the lands department? Is de facto transaction binding as the one which is done through utterance of the formula?
