No one person can have more than one Will and even if they do, the only valid Will is the most recent or latest. Once that latest Will is properly made, then any previous Will is automatically revoked or made invalid. For e.g. if you made a Will yesterday and on second thought decided that the child who looks out for you least should not get as much as you left him/her, you can visit your Attorney-at-Law the following day and have a new Will prepared. Yesterday’s Will is revoked or made invalid the moment today’s new Will is duly executed or signed. It is the rare case in which the last is actually the first and only!
