“4. At the time of execution neither party is bound by the terms of the document which he has executed, it being their mutual intention that neither will be bound until the executed parts are exchanged. 5. The act of exchange is a formal delivery by each party of its part into the actual or constructive possession of the other with the intention that the parties will become actually bound when exchange occurs, but not before. 6. The manner of exchange may be agreed and determined by the parties. The traditional method was by mutual exchange across the table…”
“On the facts as the Tribunal has found them Mr Aslam signed his part of the agreement at the request of Mr Rehman and immediately handed it to Mr Rehman on14 September 2018 . There is no evidence that Mr Rehman handed his copy or offered to deliver his copy to Mr Aslam, as counsel points out. However, in my judgement the trust reposed in Mr Rehman by Mr Aslam at this point meant that Mr Rehman was acting as Mr Aslam’s agent in respect of the impending sale of 189 Walton Road. As I have found, it was Mr Rehman who arranged the appointment with Lynsey Sait and Turner and told them about the agreement to sell 189 Walton Road. Mr Rehman took the lead at the interview but Mr Aslam was named as the client in the invoice. In this sense there was a delivery to Mr Aslam’s agent and this is sufficient to mean there was an exchange. As Buckley LJ said in Domb v Isoz[1980] Ch 548 at 577 when discussing an exchange of contracts by telephone: ‘such possession need not be actual or physical possession. Possession by an agent of the party or of his solicitor in such circumstances that the party or solicitor in question has control over the document and can at any time procure its physical possession will in my opinion suffice. In such a case possession of the agent is the possession of the principal.’”
