Since the contract is meant to be a record of everything you agreed to with the seller, anything you said orally is not part of the contract and you shouldn't rely on it. If you are worried that parts of your agreement with the seller are not in the contract of sale, you should let your lawyer know as soon as possible. Contracts signed by a buyer within three clear working days before or after a publicly announced auction are not subject to the statutory cooling off provisions generally applicable to residential property buyers.
