Westpac Banking Corporation v Paterson

Westpac Banking Corporation sought to enforce a mortgage against a former wife and her ex-husband. The case was heard in the Federal Court of Australia, following an initial proceeding in the Supreme Court of New South Wales. The dispute centred on whether the ex-wife, who was under a special disability, had been subjected to undue influence by her ex-husband in executing the mortgage. The court had to determine whether Westpac was aware of the undue influence and if the mortgage was therefore voidable.

The court considered whether Westpac was aware or ought to have been aware of the undue influence exerted by the ex-husband over the ex-wife. It was also necessary to determine whether the ex-wife was indeed under a special disability at the time of executing the mortgage. If undue influence was found, the court would need to decide whether Westpac could still enforce the mortgage or if it should be set aside. The court examined the evidence and testimonies presented regarding the relationship dynamics and the circumstances surrounding the execution of the mortgage.

The court concluded that Westpac was not aware of any undue influence and that the ex-wife was not under a special disability. Therefore, Westpac was entitled to enforce the mortgage. The court found that the ex-wife had willingly participated in the transaction and had not been coerced by her ex-husband. The undue influence claim was dismissed, and the mortgage was upheld as valid.

The court ordered that the appeal be allowed, the declaration and orders made by the primary judge be set aside, and the amended cross-claim be dismissed. The ex-wife was ordered to pay the cross-respondent’s costs of the proceeding, and Westpac was awarded its costs of the appeal.
