Background
Joseph Patrick Whyte and Diana Hendershot have one minor child in common. Following Hendershot’s petition for paternity, legal decision-making, parenting time, and child support, the parties engaged in considerable litigation. In November 2023, the Maricopa County Superior Court designated Whyte as a vexatious litigant. Whyte timely filed notice of appeal in November 2025, stating he appealed the vexatious litigant designation order. The superior court entered a signed order reflecting the designation in February 2026.
The Court’s Holding
The Arizona Court of Appeals affirmed the vexatious litigant designation. Although Whyte’s notice of appeal specified the vexatious litigant designation as the subject of appeal, his opening brief failed to include any argument on that issue. Instead, he argued unrelated matters concerning findings, opportunity to be heard, and post-decree proceedings regarding financial disclosure and discovery.
The court held that Whyte waived his arguments by failing to comply with Arizona Rule of Civil Appellate Procedure 13, which requires briefs to contain legal authorities and appropriate record citations. The court noted that Whyte provided no reasoning beyond general assertions of error and, when asked for record citations, stated “you guys can review the record I dont give a shit anymore [sic].” The court affirmed that unrepresented litigants are held to the same appellate procedure standards as attorneys.
The court awarded Hendershot reasonable attorneys’ fees and costs pursuant to Arizona Revised Statutes § 25-324.
Key Takeaways
- Appellants must comply strictly with appellate procedure rules; failure to include arguments in the opening brief constitutes waiver of those issues.
- Unrepresented litigants are held to the same appellate standards as licensed attorneys.
- The court will not stretch judicial leniency when an appellant fails to make a bona fide effort to comply with rules of appellate procedure.
- Prevailing parties may recover reasonable attorneys’ fees in family law vexatious litigant designations.
Why It Matters
This decision reinforces strict enforcement of appellate procedure rules and demonstrates significant consequences for litigants—particularly self-represented ones—who fail to comply with briefing requirements. A notice of appeal that identifies one issue does not permit the appellant to argue different issues in the opening brief, and such deviation results in forfeiture of all contentions. This case illustrates how procedural noncompliance can result in affirmance regardless of the merits of underlying claims.
For family law practitioners, the opinion confirms that vexatious litigant designations—which may restrict a party’s right to file future motions or appeals without judicial permission—are vigorously enforced on appeal when the appellant fails to properly present his case.
