'We hereby agree acknowledge and confirm as follows:
'In the face of such evidence, their Lordships are of opinion that it is quite impossible to uphold the security given by Mrs. Duval. It is open to the double objection of having been obtained by a trustee from his cestui que trust by pressure through her husband and without independent advice, and of having been obtained by a husband from his wife by pressure and concealment of material facts. Whether the security could be upheld if the only ground for impeaching it was that Mrs. Duval had no independent advice has not really to be determined. Their Lordships are not prepared to say it could not. But there is an additional and even stronger ground for impeaching it. It is, in their Lordships' opinion, quite clear that Mrs. Duval was pressed by her husband to sign, and did sign, the document, which was very different from what she supposed it to be, and a document of the true nature of which she had no conception. It is impossible to hold that Campbell or Turnbull & Co. are unaffected by such pressure and ignorance. They left everything to Duval, and must abide the consequences.'

'Banks and building societies will advise private individuals proposing to give them a guarantee or other security for another person's liabilities that: (i) by giving the guarantee or third party security he or she might become liable instead of or as well as that other person; (ii) he or she should seek independent legal advice before entering into the guarantee or third party security. Guarantees and other third party security forms will contain a clear and prominent notice to the above effect.'
