13 Del. C. § 8-508: Genetic testing when specimen is not available [Effective until Dec. 6, 2026].

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

(1) The parents of the man;

(2) Brothers and sisters of the man;

(3) Other children of the man and their mothers; and

(4) Other relatives of the man necessary to complete genetic testing.

(b) Issuance of an order under this section requires a finding that a need for genetic testing outweighs the legitimate interests of the individual sought to be tested.
