All proceedings in which the insolvent insurer is a party or is obligated to defend a party in a court in this state shall, subject to waiver by the board of governors of the association in specific cases involving covered claims, be stayed for 90 days or additional time as ordered by a court from the date the insolvency is determined or an ancillary proceeding is instituted in this state, whichever is later, to permit proper defense by the association for all pending causes of action as to any covered claims arising from a judgment under a decision, verdict, or finding based on the default of the insolvent insurer or its failure to defend an insured. The association, either on its own behalf or on behalf of the insured, may apply to have this judgment, order, decision, verdict, or finding set aside by the same court or administrator that made the judgment, order, decision, verdict, or finding and shall be permitted to defend against the claim on the merits.
