Meaning
High-standard evidentiary material that leaves no distinct or reasonable doubt about the true intentions of contracting parties is required to overcome the written text of a signed agreement. Courts demand convincing proof before they will alter a signed document, as the written word is presumed to be the definitive record of the deal. This demanding standard protects the security of contracts by preventing parties from easily claiming that a draft contains an error.
Evidentiary Threshold
This standard is higher than the balance of probabilities but does not require the absolute certainty of criminal cases. It sits at a level where the evidence must be clear, cogent, and leave the court with a strong conviction that a mistake occurred. Parties must present detailed, consistent records to meet this requirement.
Judicial Standard
Equity courts apply this measure to ensure that contracts are not lightly disrupted. An applicant must show that the written document fails to represent the shared intention of the parties. This prevents the court from making a new contract that the parties did not agree to.
Litigation Strategy
Preparing a claim under this high standard requires collecting every piece of precontractual communication. Lawyers must construct a clear narrative of how the error entered the text. The financial investment in organizing this evidence is substantial but necessary.
