Can waiver and estoppel defenses prevent child support enforcement when an order already exists? Evans v. Evans Explained

In Evans v. Evans, the Utah Court of Appeals clarified important limitations on waiver and estoppel defenses in child support enforcement cases. The case arose when Richard Evans challenged both the adequacy of notice for a child support order and Cahoon’s ability to seek reimbursement for unpaid support.

Evans first argued he lacked proper notice of the child support order. However, the court found that Evans had signed an “Acceptance of Service, Waiver, and Consent To Default” document at Cahoon’s request. Under Utah Code section 78B-6-315, this waiver eliminated the need for formal service and provided adequate notice. The court emphasized that by signing this document, Evans waived his right to answer the complaint and agreed that default judgment could be entered against him.

Evans also challenged the timing of Cahoon’s complaint filing under Utah Rule of Civil Procedure 3(a)(2), which requires complaints to be filed within ten days of service when an action is commenced by summons service. The court noted that Cahoon appeared to seek relief under Rule 104, which governs divorce cases and has no timeliness requirement when notice is waived.

Most significantly, Evans argued that Cahoon had waived any claim to child support arrearages and was estopped from seeking them. The court rejected this argument based on Utah Code section 78B-12-109(1), which provides that “waiver and estoppel shall apply only to the custodial parent when there is no [child support] order already established by a tribunal.” Since a child support order already existed, waiver and estoppel principles simply did not apply.

This decision reinforces that once a child support order is in place, parents cannot rely on informal agreements or conduct to avoid their support obligations. The statutory framework prioritizes consistent support payments over private arrangements between parents.
