Francesco Franco Cammisa and his wife Jessie Agnes Maria Cammisa each instructed an accountant to draft separate wills. At a meeting on 15 September 1999, both read and approved their respective wills but inadvertently signed the will prepared for the other, resulting in ‘crossed wills’. All other statutory formalities for the execution of wills were complied with. Franco died first in October 2004. The Master accepted and registered, as Franco’s will, the document drafted for him but mistakenly signed by Jackie. After both deaths, the error was discovered. The respondents applied to the High Court to rectify the wills to reflect the true testamentary intentions. Jackie’s grandchildren opposed the application and brought a counter-application to set aside the will registered as Franco’s, contending the wills were invalid for non-compliance with the Wills Act and that rectification was impermissible.
