(b) Procedures
(1) Service on Natural Persons
Papers served on a natural person may be served at the natural person's residential address, as reflected in the Central Registration Depository, if applicable. When a Party or other person responsible for serving such person has actual knowledge that the natural person's Central Registration Depository address is out of date, duplicate copies shall be served on the natural person at the natural person's last known residential address and the business address in the Central Registration Depository of the entity with which the natural person is employed or affiliated. Papers may also be served at the business address of the entity with which the natural person is employed or affiliated, as reflected in the Central Registration Depository, or at a business address, such as a branch office, at which the natural person is employed, or at which the natural person is physically present during a normal business day. The Hearing Officer may waive the requirement of serving documents (other than complaints) at the addresses listed in the Central Registration Depository if there is evidence that these addresses are no longer valid, and there is a more current address available. If a natural person is represented by counsel or a representative, papers served on the natural person, excluding a complaint or a document initiating a proceeding, shall be served on the counsel or representative.
(2) Service on Entities
Papers served on an entity shall be made by service on an officer, partner of a partnership, managing or general agent, a contact employee as set forth on Form BD, or any other agent authorized by appointment or by law to accept service. Such papers shall be served at the entity's business address as reflected in the Central Registration Depository, if applicable; provided, however, that when the Party or other person responsible for serving such entity has actual knowledge that an entity's Central Registration Depository address is out of date, duplicate copies shall be served at the entity's last known address.
