In case of land-surveyor-in-training, the certificate shall state that the applicant has successfully passed the examination in fundamental surveying subjects required by the board and has been enrolled as a "land-surveyor-in-training." All certificates of registration shall show the full name of the registrant, shall have a serial number, and shall be signed by the chair and the secretary of the board and by the director.
The issuance of a certificate of registration by the board shall be prima facie evidence that the person named therein is entitled to all the rights and privileges of a registered professional engineer or a registered land surveyor, while the said certificate remains unrevoked and unexpired.
Each registrant hereunder shall upon registration obtain a seal of the design authorized by the board, bearing the registrant's name and the legend "registered professional engineer" or "registered land surveyor." Plans, specifications, plats, and reports prepared by the registrant shall be signed, dated, and stamped with said seal or facsimile thereof. Such signature and stamping shall constitute a certification by the registrant that the same was prepared by or under his or her direct supervision and that to his or her knowledge and belief the same was prepared in accordance with the requirements of the statute. It shall be unlawful for anyone to stamp or seal any document with said seal or facsimile thereof after the certificate of registrant named thereon has expired or been revoked, unless said certificate shall have been renewed or reissued.
