In this regulation, “filed” means delivered to and date-stamped by the Department. A certificate is effective for a period of 5 years from the date it is filed. Every 5 years following the year in which a certificate is filed or renewed, a person who has filed or renewed a certificate and who wishes to renew the certificate shall cause to be filed a completed renewal application within 6 months before the end of the 5-year period. A renewal application that is completed and filed extends the certificate for 5 years from the end of the previous 5-year period. The Department shall determine the form of a renewal application. Except for certificates canceled on the Department's records, the Department may mail a notice of impending expiration of the trade name, during the 6-month period mentioned in §C of this regulation, to the person listed as principal or owner in the certificate, amended certificate, or most recent renewal application. A completed renewal application shall: State the trade name being renewed and the current address of the business conducted under the trade name; State that the trade name certificate is being renewed; State the SDAT identification number of the associated business; Be signed by a person listed as principal or owner in the certificate, amended certificate, or most recent renewal application; and Be accompanied by a fee set by Corporations and Associations Article, §1-406, Annotated Code of Maryland. The Department's failure to mail a renewal application form pursuant to §F of this regulation does not suspend the obligation to file a completed renewal application.
