Del. Code tit. 16 § 3127
In cases of acknowledgment or establishment of paternity, the State Registrar, upon receipt of a court order, an administrative order or a properly executed acknowledgment of paternity, executed or issued in this State or any other state, which establishes paternity or creates a presumption of paternity under the law of the state in which it was executed or issued, shall prepare an amended or new certificate of birth, as the case may be, consistent with the document. The fact that the father-and-child relationship was declared after the child's birth shall not be ascertainable from the amended or new certificate, but the actual place and date of birth shall be shown. The evidence upon which the amended or new certificate was made and the original birth certificate shall be sealed and filed and may be opened only upon court order or upon application of the Division of Child Support Services certifying that the child for whom information is sought is the subject of a child support case administered by the Division under Title IV-D of the federal Social Security Act [ 42 U.S.C. § 651 et seq.]
