 Complications can arise where the transaction was entered into by the victim of undue influence with a third party (as opposed to with the person who exercised undue influence).By far the most common examples of this in the case law seem to be where a wife has either given a guarantee or granted security over the matrimonial home to support the business debts of her husband, and it is alleged that the husband has exercised undue influence over the wife to persuade her to enter into the arrangement.The courts will not presume undue influence into the husband/wife relationship.
