Del. Code tit. 21 § 2114
Whenever the owner of any motor vehicle, trailer or semitrailer, which has been stolen or embezzled, files an affidavit of the fact thereof with the Department, the Department shall forthwith suspend the registration of such vehicle and shall not transfer the title of or reregister the vehicle until it has been notified that the owner has recovered such vehicle. The notice shall be effective for the current registration period, but, if during that time the vehicle is not recovered, a new affidavit to like effect may be filed with the Department, and the notice shall be effective for a further period of 12 months. Thereafter like notices may be given effective from year to year. Every owner who has filed an affidavit of theft or embezzlement shall immediately notify the Department of the recovery of such vehicle, and failure so to do within 30 days after such recovery shall be punished as provided in § 2116 of this title.
