Background
In 2005, the Department of Revenue filed an action on behalf of a child’s mother to establish paternity and child support against Phillip Seymore. The Department effected substitute service by serving the mother, who represented that she resided with Seymore. A hearing officer determined paternity, and the trial court entered a final judgment establishing child support obligations. Seymore did not seek rehearing or appeal.
Beginning in 2010, Seymore actively litigated the case, filing motions for DNA testing, dismissal, rehearing, and modification of child support obligations. He appeared telephonically at hearings and pursued affirmative relief in multiple proceedings across Broward and Volusia Counties. However, not until 2016—eleven years after entry of judgment—did Seymore first challenge the validity of service of process, claiming he did not reside at the address where substitute service was made.
In 2024, after the case transferred back to Broward County, Seymore moved to vacate the judgment and quash service. The trial court agreed the substitute service was defective and granted the motion to vacate. The Department appealed.
The Court’s Holding
The Fourth District reversed, holding that although substitute service on the mother was technically defective, Seymore waived any objection to personal jurisdiction through his years of active litigation without timely raising the issue. The court distinguished between void judgments (entered without notice, challengeable anytime) and voidable judgments (where the defendant has actual notice but service is defective, subject to waiver). Under Florida law, defective service renders a judgment voidable only when the defendant lacks notice altogether.
The court found Seymore had actual notice of the proceedings long before raising the service challenge. His conduct—filing motions for DNA testing and dismissal in 2010, seeking rehearing in 2011, filing a modification petition in 2013, and appearing telephonically at hearings—constituted a general appearance and active participation in litigation that waived any objection to personal jurisdiction. This delay and active litigation for eleven years before raising the service defect defeated any challenge.
The court also noted that allowing Seymore’s successive motions to vacate would amount to an impermissible successive attack on a voidable judgment, violating principles of finality. The judgment remained enforceable despite the service defect.
Key Takeaways
- Defective service of process renders a judgment voidable (not void) when the defendant has actual notice of proceedings.
- A defendant waives objections to personal jurisdiction by seeking affirmative relief and actively litigating without timely raising service challenges.
- Protracted delay—here, eleven years—in raising a service defect weighs heavily against relief through successive motions to vacate.
- Principles of finality prevent endless re-litigation of service-based challenges to judgments.
Why It Matters
This decision reinforces that child support judgments and other civil judgments are protected by the finality doctrine even when service is technically defective, provided the defendant received actual notice and actively participated in the litigation. Defendants cannot strategically sit silent, actively litigate for years, and then suddenly challenge jurisdiction years later.
For enforcement of child support orders and other judgments, the ruling provides critical protection against belated collateral attacks. It establishes that a defendant’s conduct—especially seeking affirmative relief—constitutes meaningful participation that waives service defects and locks in jurisdiction, preventing defendants from using procedural technicalities to escape long-standing obligations after years of knowledge and involvement.
