(b) Papers Requiring Proof of Service. The register shall not accept for filing any petition or paper requiring service unless it is accompanied by (1) a signed certificate showing the date and manner of service as prescribed in Rule 6-125 or (2) a signed statement that, for reasons set forth in the statement, there is no person entitled to service. A certificate of service is prima facie proof of service.
