Other papers that are required to be filed shall be deemed timely if, on the same day such papers are served, they are also hand-delivered, mailed via U.S. Postal service first class mail, delivered by electronic mail, or sent by courier to FINRA.
(b) Where to File
All papers required to be filed pursuant to the [Rule 9200] Series and any notice of appeal or review required to be filed pursuant to the [Rule 9300] Series shall be filed with the Office of Hearing Officers. All other papers required to be filed pursuant to the [Rule 9000] Series shall be filed where specified in the Rule, or if not specified in the Rule, with the Adjudicator, unless the Adjudicator orders otherwise.
(c) Certificate of Service
Papers filed with an Adjudicator or the Office of Hearing Officers shall be accompanied by a certificate of service stating the name of the person or persons served, the date on which service is made, the method of service and, if service is not made in person, the address to which service is made. Such certificate shall be executed by the person who made the service. If the method of service on a Party is different from the method of service on any other Party, the certificate shall state why such different method was used.
