Del. Code tit. 21 § 810
When a person's name and address is forwarded to the Division of Motor Vehicles pursuant to § 808(b) of this title and the offense was 1 for which the person received service of the notice or summons by mail and the person has not responded within the required time by either paying the civil penalty or requesting a hearing or, submitting an affidavit stating that the person was not the driver, if applicable, the Division of Motor Vehicles may deny the renewal of the registration of the owner's vehicle operated at the time the summons was issued. The Division shall register any vehicle for which it has refused registration upon proof that the person has paid the civil penalty, costs, or both, or has appeared in court following a default in appearance or payment and made arrangements to pay the civil penalty or costs or both or has had a default judgment vacated and been found not responsible.
