Contracts are often drafted as an instrument where the contract contains power of order (which must be enforced under English law) or where the contract does not contain consideration (e.g. B no service fees or no prices for purchased goods/assets).  Historically, documents have been used for many types of contracts. However, over time, their use has been limited, so that today they are mainly used only for agreements that are not subject to consideration or where the law requires it. In this article, we will see what a witness is, why it is important and what to do if you do not have one. A witness signature may be useful for evidenting purposes. If a party later tells the agreement that they did not sign, the person who saw the party`s signature may be called for confirmation.
