13 Del. C. § 8-509: Genetic testing when specimen not available [Effective Dec. 6, 2026].

(a) Subject to subsection (b) of this section, if a genetic-testing specimen is not available from an alleged genetic parent of a child, for good cause and under circumstances the court considers to be just, the court may order any of the following individuals to submit specimens for genetic testing:

(1) A parent of the alleged genetic parent;

(2) A sibling of the alleged genetic parent;

(3) Another child of the alleged genetic parent and the individual who gave birth to the other child; and

(4) Another relative of the alleged genetic parent necessary to complete genetic testing.

(b) To issue an order under this section, the court must find that a need for genetic testing outweighs the legitimate interests of the individual sought to be tested.
