502.02 Correspondence Signature Requirements
Correspondence signature requirements are covered here including hand written signatures and S-signatures (which is a signature inserted between forward slash marks that’s not handwritten).
This section also covers certifications and how the person submitting the certification should believe the signature on the document is authoritative. In addition, a discussion on ratification, confirmation and authenticity also ensue. The Office may require evidence when the authenticity of a signature is in question.
