All proceedings in which the insolvent insurer is a party or is obligated to represent a party in a court in New Mexico shall be stayed for not to exceed six months from the date of a finding of insolvency to permit proper representation by the association of all pending causes of action. As to covered claims arising from a judgment under a decision, verdict or finding resulting from 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 the judgment, order, decision, verdict or finding set aside by the same court, administrator or arbitrator that made it and may defend against the claim on its merits.
