Guardianship is the possession by a non-parent of the powers, rights, and duties which are necessary to protect, manage and care for a child. A Guardian has the legal authority to take care of the child as if he/she were the child’s parent until the child turns 18 years of age.
Included in a Guardianship Order is a
Custody Order. Therefore, a Guardian has the same legal authority to care for the child as a parent would. However, unlike a parent, the Guardian cannot be held liable by a third party for something the child has done wrong simply because he/she is the guardian. Additionally, the Court also has the right to limit any of the powers and duties granted to a Guardian.
