Ohio Rev. Code § 3111.74: Acknowledgment conflicting with presumption of paternity.

If the hospital knows or determines that a man is presumed under section 3111.03 of the Revised Code to be the father of a child and that the presumed father is not the man who signed or is attempting to sign an acknowledgment with respect to the child, the hospital shall take no further action with regard to the acknowledgment and shall not send the acknowledgment to the office of child support.
