Ohio Code § 1308.04

§ 1308.04.

The following rules apply in an action on a certificated security against the issuer: (A) Unless specifically denied in the pleadings, each signature on a security certificate

or in a necessary indorsement is admitted; (B) If the effectiveness of a signature is put in issue, the burden of establishing effectiveness

is on the party claiming under the signature, but the signature is presumed to be

genuine or authorized; (C) If signatures on a security certificate are admitted or established, production of

the certificate entitles a holder to recover on it unless the defendant establishes

a defense or a defect going to the validity of the security; (D) If it is shown that a defense or defect exists, the plaintiff has the burden of establishing

that the plaintiff or some person under whom the plaintiff claims is a person against

whom the defense or defect cannot be asserted.
