The response must be signed by the owner, someone with legal authority to bind the owner (e.g., a corporate officer or general partner of a partnership), or a practitioner qualified to practice under § 11.14 of this chapter, in accordance with the requirements of § 2.193(e)(2).
(c) If no response is filed within this time period, the registration will be cancelled, unless time remains in the grace period under section 8(a)(3) of the Act. If time remains in the grace period, the owner may file a complete, new affidavit.
