“This codicil is made pursuant to an agreement made between my husband and me for the disposal of our property in a similar way by mutual testamentary dispositions.”
“(g) The discussion led to an agreement between Mr Walters and the Deceased that the solution that Andrew offered should be adopted and that Andrew be asked to implement the arrangement under which their respective wills in the agreed form could only be changed by agreement during their joint lives and could not be changed by the survivor.”
“..that in return for T1 agreeing to make a will in form X and not to revoke it without notice to T2, then T2 will make a will in form Y and agree not to revoke it without notice to T1. If such facts are established then upon the death of T1 equity will impose upon T2 a form of constructive trust (shaped by the exact terms of the contract that T1 and T2 have made.) The constructive trust is imposed because T1 has made a disposition of property on the faith of T2’s promise to make a will in form Y, and with the object of preventing T1 from being defrauded.”
