Your will can include information on who you wish to be the legal guardian of your minor children after your passing.
The appointment of a guardian usually only operates if the children have no surviving parent. Although it is possible to appoint a guardian who will assist the surviving parent.
A guardian does not have to be related to the children, but it is wise to select a guardian who you know well and who you trust will care for your children as you would do. It is wise to appoint either a couple or a single person to act as guardian.
Your chosen guardian needs to agree to the role before your will is finalised.
