Ohio Rev. Code § 3109.69: Limitations on authority granted by affidavit.

Once a caretaker authorization affidavit has been executed under section 3109.67 of the Revised Code, the grandparent may exercise care, physical custody, and control of the child, including enrolling the child in school, discussing with the school district the child's educational progress, consenting to all school-related matters regarding the child, and consenting to medical, psychological, or dental treatment for the child. The affidavit does not affect the rights and responsibilities of the parent, guardian, or custodian regarding the child, does not grant legal custody to the grandparent, and does not grant authority to the grandparent to consent to the marriage or adoption of the child.
