N.J. Stat. § 45:8-36
The board shall issue a license certificate upon payment of the application fee as provided in this chapter, to any applicant who, in the opinion of the board, has satisfactorily met all the requirements of this chapter, and who has paid the license fee to cover licensure for the year or fraction thereof in which such license is issued. In the case of a licensed professional engineer the certificate shall authorize the practice of the applicant as a "professional engineer" and in the case of a licensed land surveyor as a "land surveyor," or as "professional engineer and land surveyor" when the applicant qualifies in both classifications. Certificates of license shall show the full name of the licensee, shall have a license number and shall be signed by the president and the secretary-director of the board under the seal of the board. The issuance of a license certificate by this board shall be evidence that the person named therein is entitled to all the rights and privileges of a licensed professional engineer or a licensed land surveyor, or as both as the case may be, while said certificate remains unrevoked, unexpired, or is not on a retired status list.
Each professional engineer or land surveyor shall upon receipt of license certificate, obtain a seal of a design authorized by the board, bearing his name, license number and the legend "Licensed Professional Engineer," "Licensed Land Surveyor," or "Licensed Professional Engineer and Land Surveyor," as the case may be. Plans, specifications, plats, and reports issued by persons authorized under this chapter shall be sealed with said seal, during the life of the licensee's certificate, but it shall be unlawful for anyone to stamp or seal any documents with said seal after the certificate of the licensee named thereon has expired, has been revoked, or is on a retired status list, unless said certificate shall have been renewed, reissued or reinstated from retirement status as provided pursuant to section 3 of P.L. 1995, c.36 (C.45:8-36.2). The exact method of fulfilling the requirement as to the sealing of documents shall be regulated by the board.
All professional engineers licensed by this board prior to the passage of this chapter, shall continue to practice under the various classifications heretofore granted and within the branches of engineering indicated or may, upon application therefor, and the payment of a fee of $5.00 receive a new certificate under the title "professional engineer"; provided, said professional engineer presents evidence satisfactory to the board of his qualifications to practice in the field of general engineering comprehended in the title "professional engineer."
All license certificates shall be recorded by the board in the office of the Secretary of State, in a book kept for that purpose and any recording fee as may be provided by law shall be paid by the applicant before the license certificate is delivered.
The examining board shall be empowered to issue a certificate of registration as "Engineer-in-Training" or "Surveyor-in-Training," as the case may be, to an applicant who meets the qualifications outlined elsewhere herein.
An applicant who meets the requirements of this act shall receive a certificate of registration as "Engineer-in-Training," or "Surveyor-in-Training," whichever is applicable, which certificate may remain in effect for a period of 10 years from the date of issuance.
