I have heard learned counsel for the appellants-defendants and appraised the paper book. It is a matter of record that the respondentplaintiff has presented himself at Sub Registrar's office on 11.01.2006. PW1, Dalip Kumar, one of the marginal witnesses, has deposed to prove the agreement to sell Ex.P1. PW2, Lachhman Dass, deed writer has deposed that he scribed the agreement to sell on the asking of Jarnail Singh. PW-3, Om Parkash, has also deposed on the lines as pleaded in the plaint and proved his signatures over the agreement. The defendants have not been able to dispel the circumstances under which Jarnail Singh appended his signatures. The story of commission agent has not been proved. Once the defendants have denied the execution of the agreement, they have to discharge the onus by disproving the signatures of Jarnail Singh on agreement to sell before the Sub Registrar. The fact remains that the plaintiff was always ready and willing to perform his part of the contract
