The Delaware Affidavit to Release Retained License Plate to Relative is a legal form used in the state of Delaware to release a license plate to a relative of the former owner. The form is designed to allow a legal transfer of ownership of a vehicle through a family member rather than through a third party. This form is necessary when the previous owner is deceased or the license plate has been retained by the state of Delaware for some other reason. There are two types of Delaware Affidavit to Release Retained License Plate to Relative: the Certificate of Transfer and the Registration Certificate. The Certificate of Transfer is used when the vehicle was previously registered to a relative of the deceased former owner and the Registration Certificate is used when the vehicle was not registered to a relative of the deceased former owner. Both forms must be completed and notarized in order for the license plate to be released.
