Del. Code tit. 24 § 2711
The Board shall issue a license to each applicant who meets the requirements of this chapter for licensure as a land surveyor and who pays the fee established under § 2710 of this title.
Each license shall be renewed biennially, in such manner as is determined by the Division, and upon payment of the appropriate fee and submission of a renewal form provided by the Division, and proof that the licensee has met the continuing education requirements established by the Board.
The Division or its designee shall notify every licensee of the date of expiration of license and the amount of the fee that shall be required for renewal at least 1 month prior to the expiration thereof. Failure to give or receive such notice shall not prevent the license from becoming invalid after its expiration date.
The Board, in its rules and regulations, shall determine the period of time within which a professional land surveyor may still renew license, notwithstanding the fact that such licensee has failed to renew on or before the renewal date. The Board shall charge a late fee equivalent to twice the sum of the unpaid renewal fee.
