An error is a false conviction held by one or both parties to a contract at the time of its creation. There may be an error regarding: transfer error:An error when transferring a contract through an intermediary. Note that it is important to determine whether the non-crazy party knows that the other party does not include a term in the contract. If the non-false party knows or must know that the other party has made a unilateral error, the result is usually the termination of the contract (cancellation). On the other hand, if the other party was not aware of the error, the contract can be reformed (rewritten). There are a number of differences between frequent errors and other forms of error. Writing a chord seems pretty simple – until you actually do it. One of the reasons lawyers` contracts seem stylized and superfluous is precisely because it is important to develop a language that could be imposed by strangers a decade later, who have not been part of the negotiations and who have only the words on which side they must pass. What the parties „understood without saying” cannot be understood in this way by a judge and jury who interpreted the agreement a decade after the end of a game. The last type of error involves errors when transmitted by an intermediary. The unilateral error does not apply in cases where the error relates to the quality of the purpose of the contract (see above). Illustration: Lady found a stone and sold it as topaz for 1 dollar ($25 today). It was an uncut rough diamond valued at $700 ($17,000 today).
The contract is not cancelled. There was no error because neither party knew what the stone was.  Another collapse in contract law divides errors into four traditional categories: unilateral errors, reciprocal errors, erroneous transcription and misunderstandings.  The Great Peace gives us an example of a paradigm for a treaty concluded on the basis of a frequent error, considered binding. Loan of Lord Phillips` judgment in paragraphs 31 – 94 – 162 – 164 – 166 ” … parties have been agreed on explicit contractual terms. The complainants agreed that the Great Peace is moving towards Cape Providence and that it, if reached, would escort it to be there, to save the lives of its crew, if it… The error relied on by the applicants indicates that they support the expressly agreed terms. It was that the Great Peace was in a few hours sailing from the providence cape. This error is fundamental in that the Great Peace would take about 39 hours to reach a position in which it could provide the services that were the subject of the contractual adventure… With regard to this case, with respect to the common error, the question is whether the error in the removal of the two ships led to the that the services that the Great Peace could provide were substantially different from those on which the parties had agreed … It is no doubt a common acceptance of both parties, when the treaty was concluded, that the two ships were in sufficient proximity to enable the Great Peace to perform its service.
Was the distance between the two ships so great that it disturbed this hypothesis and made the contractual adventure of performance impossible? … The fact that the vessels were significantly further apart than the applicants thought does not mean that the services that Great Peace could provide were essentially different from those provided by the parties at the time the contract was concluded. The Great Peace would arrive in time to offer several days of escort service.
