(4) A court may refuse to enter an order setting aside a parentage determination, revoking an acknowledgment of parentage, determining that a genetic father is not a child's father, or determining that a child is born out of wedlock if the court finds evidence that the order would not be in the best interests of the child.

(8) If the case is a title IV-D case, the court may appoint an attorney approved by the office of child support to represent this state's interests with respect to an action or a motion under this act. The court may appoint a guardian ad litem to represent the child's interests with respect to the action or motion.
(9) A court shall not issue an order under this act that sets aside a judgment or determination of a court or administrative agency of another state, even if the judgment or determination is being enforced in this state, or that is inconsistent with 28 USC 1738A or 28 USC 1738B.
(10) This act does not establish a basis for termination of an adoption and does not affect any obligation of an adoptive parent to an adoptive child.

The court, in its discretion, may order a nonprevailing party, including a mother who is a nonprevailing party under section 15(2), to pay the reasonable attorney fees and costs of a prevailing party.
(14) A court may extend the time for filing an action or motion under this act. A request for extension must be supported by an affidavit signed by the party requesting the extension stating facts that the party satisfied all the requirements for filing an action or motion under this act but did not file the action or motion within the time allowed under this act because of 1 of the following:
(a) Mistake of fact.
(b) Newly discovered evidence that by due diligence could not have been found earlier.
