A guardian is a person appointed in a will to assume parental responsibility for a minor child if both parents have died. The guardian becomes legally responsible for the child’s care, welfare, and upbringing.
Legal Reference:
Governed under the Children Act 1989.
A guardian must be over 18 and have parental capacity. The appointment becomes effective only upon the death of all individuals with parental responsibility.
If no guardian is named and no parent survives, the Family Court may appoint one.
