There are a couple of forms a parent can complete for this. There is a Child Medical Care Authorization Form or a Child Care Limited Power of Attorney (includes medical). A Child Care Limited Power of Attorney is a document signed and notarized by a parent giving a non-parent authority to make decisions for a minor child. It is not a court order. It is typically used by a parent who is unavailable for a period of time and wants to grant authority to another person over their child.
