Normally under Australian succession law marriage cancels a will (that is revokes the will) – unless the will was made in contemplation of marriage. In some states and the ACT testamentary arrangements can be made in contemplation of entering into a registered relationship or partnership.
Marriage affects the legality of a previously made will.
Disposing property by will, in the will-making process requires considerations to be given to what you own in your individual name, as opposed to what you might control, see further below. As only property owned in a personal or individual name can form a deceased estate, it is only this which can be transferred by will, (or the rules of intestacy).
Among the first considerations in making a will is considering what we own. Only property owned personally can form a deceased estate and be disposed of by will, but it is easy to overlook that property thought of as ‘ours’, is legally in another name. It pays to check who owns what, that which is not in your own name, is not yours to give by will.
