This discussion examines the validity of a joint will made by a husband and wife, which stipulated that their grandson would inherit their properties after both their deaths. However, the husband later executed a gift settlement deed favouring his son and grandson, transferring his own property and his share of the joint property. The advice suggests the husband's gift deed supersedes his portion of the joint will, as a testator can change their will during their lifetime. The wife's share of the joint property, however, would still pass according to her will to the grandson, though this could be subject to challenge by other legal heirs.
