North Carolina General Statutes Chapter 83A. Architects and Registered Interior Designers § 83A-10. Professional seals

(a) Architects.--Every licensed architect shall have a seal of a design authorized by the Board, and shall imprint all drawings and sets of specifications prepared for use in this State with an impression of such seal. Licensed architectural firms shall employ firm professional seals, of a design approved by the Board, for use in identifying plans, specifications and other professional documents issued by the firm, but use of such firm seals shall be in addition to and not in substitution for the requirement that the individual seal of the author of such plans and professional documents be affixed.

(b) Interior Designers.--Each registered interior designer shall obtain a seal as prescribed by the Board. A document issued by the registered interior designer and being filed for public record shall bear the signature and seal of the interior designer who prepared or approved the document and the date on which it was sealed. The signature, date, and seal shall be evidence of the authenticity of the document. No registered interior designer shall affix, or permit to be affixed, his or her seal or signature to any plan, specification, drawing, or other document that depicts work that he or she is not competent or certified to perform.
