It is the duty of the payee to present the cheque within a reasonable time, and the drawer should ensure that he has to keep sufficient balance in his account. The payee may also request for revalidation of the cheque if the cheque was not presented within the limitation period, and the drawer has to oblige him. The drawer (Purchaser) can not be held responsible for negligence of the payee (Seller).
As a courtesy, you may request through regd notice to the seller to encash the cheque and keep such service proof of registration. This is not an issue and just apprehension, and your seller appears to be a confident man and believes in your credentials and your integrity, as such instances are very rare.
