10 Del. Admin. Code § 202-19.0
Until such time as a name is imprinted or placed upon the rear portion of the lottery ticket in an area designated for "name", a lottery ticket which has been sold will be owned by the physical possessor of said ticket. Unsold tickets remain the property of the Lottery Office. When a name is placed on the rear of said ticket in the place designated therefor, the person(s) whose name(s) appear in that area will be the owner(s) of said ticket and will be entitled to any prize attributed thereto. Unless there is a conflict between the information on the claim form and the signature(s) on the back of the ticket, the Lottery Office shall pay to the person(s) whose name(s) appear on the back of the ticket in the designated space; provided, however, if more than one name appears on the rear of the lottery ticket, one of those persons whose name appears thereon may be designated to receive payment. This may be done by indicating on the claim form and by the signature on the claim form of all persons whose names appear on the rear of the ticket. The person(s) appearing for payment must be the same as those whose name(s) appear on the rear portion of the lottery ticket in the designated space.
