Saunders (Executrix of the Will of Rose Maude Gallie, Deceased) v Anglia Building Society: HL 9 Nov 1970

The Appellant had signed an assignment of her lease in favour of her nephew. She said she thought the effect of it would protect her right to continue to live in the house. She now appealed rejection of her plea of non est factum.
Held: The common law doctrine of non est factum has a very narrow and limited application. The transaction must be essentially different in substance or in kind from the transaction intended. The plea is available to a narrow class of persons, namely, those who are: unable to read owing to blindness or illiteracy; or permanently or temporarily unable, through no fault of their own, to have without explanation any real understanding of the purport of a particular document, whether that lack of understanding be from defective education, illness or innate incapacity.
Lord Wilberforce said: ‘leaving aside negotiable instruments to which special rules may apply, a person who signs a document, and parts with it so that it may come into other hands, has a responsibility, that of the normal man of prudence, to take care what he signs, which, if neglected, prevents him from denying his liability under the document according to its tenor. I would add that the onus of proof in this matter rests upon him.’
Lord Reid said: ”the matter generally arises when an innocent third party has relied on a signed document in ignorance of the circumstances in which it was signed, and where he will suffer loss if the maker of the document is allowed to have it declared a nullity.’
. . And ‘The plea cannot be available to anyone who was content to sign without taking the trouble to try to find out at least the general effect of the document. Many people do frequently sign documents put before them for signature by their solicitor or other trusted advisors without making any inquiry as to their purpose or effect. But the essence of the plea non est factum is that the person signing believed that the document he signed had one character or one effect whereas in fact its character or effect was quite different. He could not have had such a belief unless he had taken steps or been given information which gave him some grounds for his belief. The amount of information he must have and the sufficiency of the particularity of his belief must depend on the circumstances of each case.’
