CIBC Mortgages Plc v Pitt [1994]

CIBC Mortgages Plc v Pitt [1994] AC 200 revolved around allegations of undue influence within a married couple in the context of a joint loan secured by their matrimonial home.

The husband, exerting pressure on his wife, persuaded her to take out a loan from CIBC, secured against their home, with the stated purpose of investing in the stock market to improve their standard of living. Crucially, the loan agreement, unbeknownst to the wife, also involved the remortgaging of their home to purchase a second property. The husband, using the borrowed funds, bought shares in his name, charging them to borrow more money and acquire additional shares. However, the stock market subsequently crashed, leading to the creditors selling the husband's shares. CIBC then sought possession of the Pitts' home.

The wife argued that she was a victim of undue influence and misrepresentation regarding the true nature of the loan. The trial judge acknowledged the presence of undue influence and the serious disadvantage suffered by the wife. However, he concluded that the husband was not an agent of CIBC, and therefore, the bank was not affected by his misconduct. The misrepresentation claim was also dismissed. The Court of Appeal upheld this decision.

The House of Lords ultimately ruled in favour of CIBC, finding that the surety agreement was valid and not subject to avoidance. Despite acknowledging the presence of actual undue influence, the court determined that CIBC was not put on inquiry because there was no indication that the transaction did not serve the joint benefit of both the husband and wife. Lord Browne-Wilkinson's comments added nuances to the ruling. He clarified that manifest disadvantage, while relevant to proving undue influence in certain cases, was not a prerequisite for establishing actual undue influence.

Moreover, the court emphasised the crucial distinction between joint advance and surety cases. In a surety transaction, where the wife provides a guarantee for the husband's debts, the primary benefit accrues to the husband. Conversely, in a joint advance involving both spouses, the potential for undue influence is considered lower, especially when there is no apparent indication that the transaction deviates from the norm of joint benefit. The case underscores the significance of notice and joint benefit in determining the validity of transactions involving allegations of undue influence.

This case illustrates the importance of notice and the joint benefit in determining the validity of a transaction involving undue influence. The court emphasised that constructive notice is not applicable if there's no indication that the transaction is not for the joint benefit of the parties involved.
