“In my judgment these cases show that wherever there is a voluntary transaction by which one party intends to confer a bounty on another, the deed will be set aside if the court is satisfied that the disponer did not intend the transaction to have the effect which it did. It will be set aside for mistake whether the mistake is a mistake of law or of fact so long as the mistake is as to the effect of the transaction itself and not merely as to its consequences or the advantages to be gained by entering into it. The proposition that equity will never relieve against mistakes of law is clearly too widely stated in the authorities.”
“… i.e. transactions which create rights for persons other than the maker of the instrument, but which are not the result of a bargain, e.g. voluntary settlements, the court has a discretion to rectify in the case of mistake”
“‘… rectification is available not only in a case where particular words have been added, omitted or wrongly written as a result of careless copying or the like. It is also available where the words of the document are purposely used but it was mistakenly considered that they bore a different meaning as a matter of true construction. In such a case … the court will rectify the wording so that it expresses the true intention …’”
“Consequently rectification may be available if the document contains the very wording that it was intended to contain, but it has in law or as a matter of true construction an effect or meaning different from that which was intended.”
“If anything, it is simply a formula designed to ensure that the policy involved in equitable fraud is effectuated to keep it within reasonable bounds and to ensure that it is not used simply when parties are mistaken about the commercial effects of their transactions or have second thoughts about them. The cases certainly establish that relief may be available if there is a mistake as to law or the legal consequences of an agreement or settlement, and in the present case Mr Simmond QC ultimately accepted that, if there was a mistake, it was a mistake as to legal effect and not merely as to consequences.”
“23. The case is therefore one in which I find that Mr Strain [that is, the settlor] intended to execute a settlement in exactly the form that Mr Wilding [that was the solicitor] drafted. Insofar as he was labouring under any sort of mistake when he did so, his mistake was not as to the language, terms, meaning or effect of the settlement. The only mistake was that a payment of the£550,000 to it would be a potentially exempt transfer. “24. In my judgment a mistake of that nature is not one which the court has any jurisdiction to rectify. Since, for the reasons given, Mr Strain must be assumed to have understood the meaning of the fact of the substantive trust the powers of the settlement he executed and to have intended to execute a settlement in that form and having the legal effect it did, there is no error in the drafting of the settlement or in his understanding of it that calls for correction. Mr Strain’s only mistake was in relying in Mr Wilding’s implicit advice that the payment of money to that settlement would be a potentially exempt transfer. That was wrong and apparently negligent advice, but in the circumstances of the case the remedy of rectification is not available to cure the damage it has caused.”
