A notary seal is a controlled instrument, because anyone holding it can give documents the appearance of official authentication. California therefore controls who may manufacture one: a vendor may not produce a notary seal without a certificate of authorization issued by the Secretary of State, which confirms that the person requesting it holds a current commission in that name. So a notary whose seal is lost obtains the certificate first and presents it to the manufacturer. Two obligations accompany the replacement. The loss itself must be reported to the Secretary of State immediately in writing, because a seal in unknown hands is a fraud risk that the state needs to know about. And the notary must not perform acts requiring a seal until a replacement is in hand. A police report is not required, and no new bond arises from the loss, since the commission itself is unaffected.
