‘The equity of exoneration is a principle which arises at the difficult intersection of the law of sureties and proprietary interests in jointly-owned property – commonly, family homes. It is a common law doctrine which saw much development in the latter part of the 19th Century, and had not been properly considered by the Court of Appeal since 1898 before the case of Williams v Onyearu.’
