A married couple will require two Wills. The couple can either make a Mirror Will (with joint provisions) or they can each make a separate Single Will. This is only necessary if the couple have differing wishes. See What is a Single Will and a Mirror Will for more information regarding this.
If you are newly wed with a Will that was made prior to your wedding then you must make a Will afresh. A Will is cancelled when getting married or divorced unless the initial Will states otherwise.
