California Code, Family Code - FAM § 7648.2

(a) This section applies only to cases where support enforcement services are being provided by a local child support agency pursuant to Section 17400.

(b) Upon receipt of any motion brought pursuant to Section 7646, the local child support agency may issue an administrative order requiring the mother, child, and the previously established father to submit to genetic testing if all of the conditions of paragraphs (1) and (2) of subdivision (a) of Section 7647 are satisfied.

(c) The local child support agency shall pay the costs of any genetic tests that are ordered under subdivision (b) or are ordered by a court for cases in which the local child support agency is providing services under Title IV-D of the Social Security Act (42 U.S.C. Sec. 651 et seq.).

(d) Nothing in this section prohibits any person who has been ordered by a local child support agency to submit to genetic tests pursuant to this section from filing a notice of motion with the court seeking relief from the local child support agency's order to submit to genetic tests. In that event, the court shall resolve the issue of whether genetic tests should be ordered as provided in Section 7647.7. If any person refuses to submit to the tests after receipt of the administrative order pursuant to this section and fails to seek relief from the court from the administrative order either prior to the scheduled tests or within 10 days after the tests are scheduled, the court may resolve the question of paternity against that person or enforce the administrative order if the rights of others or the interest of justice so require.
