If you are married and living with your spouse or living with a partner he/she is strongly advised to make a will as well.
Divorce or Remarriage – Generally divorce treats a former spouse as if he or she had predeceased you so that no gift will pass to them nor can they act as executors even if named as such. In other respects, however, the rest of the Will, remains valid.
If you have made a Will and then marry or remarry, the Will may be cancelled and the rules of intestacy would apply. However, a valid Will can be made taking into account a planned marriage or remarriage which you should indicate below if appropriate.
