Alaska Stat. § 08.48.221

(a) Each registrant may obtain a seal of the design authorized by the board, bearing the registrant's name, registration number, and the appropriate legend for architect, engineer, land surveyor, or landscape architect. When a registrant issues final drawings, specifications, surveys, plats, plates, reports, or similar documents, the registrant shall stamp the documents with the seal and sign the seal. The board shall adopt regulations governing the use of seals by the registrant. An architect, engineer, land surveyor, or landscape architect may not affix or permit a seal and signature to be affixed to an instrument after the expiration of a certificate or for the purpose of aiding or abetting another person to evade or attempt to evade a provision of this chapter. The registrant, by sealing and signing the document, certifies that the document was prepared by or under the registrant's responsible charge and is within the registrant's field of practice or is design work of minor importance.

(b) Final drawings, specifications, surveys, plats, plates, reports, or similar documents containing the work of multiple fields of practice shall be sealed and signed by a registrant in each field of practice covered by the document. The registrant shall certify on the face of the document the extent of the registrant's responsibility for all work prepared under the registrant's seal.
