Delaware Code
Subchapter VI. Proceeding to Adjudicate Parentage
§ 8-631. Rules for adjudication of paternity.

The court shall apply the following rules to adjudicate the paternity of a child:

(1) The paternity of a child having a presumed, acknowledged or adjudicated father may be disproved only by admissible results of genetic testing excluding that man as the father of the child or identifying another man as the father of the child.
(2) Unless the results of genetic testing are admitted to rebut other results of genetic testing, a man identified as the father of a child under § 8-505 of this title must be adjudicated the father of the child.
(3) If the court finds that genetic testing under § 8-505 of this title neither identifies nor excludes a man as the father of a child, the court may not dismiss the proceeding. In that event, the results of genetic testing, and other evidence, are admissible to adjudicate the issue of paternity.
(4) Unless the results of genetic testing are admitted to rebut other results of genetic testing, a man excluded as the father of a child by genetic testing must be adjudicated not to be the father of the child.
(5) Paternity may not be established with regard to an alleged father without the assistance of genetic testing unless the mother of the child swears or affirms on the record or by affidavit, under penalty of perjury, that she did not have sexual intercourse with any other man at or about the time the child was conceived.
