What must a nonresident defendant show to attack an ex parte divorce for lack of jurisdiction?

To successfully challenge an ex parte divorce on the grounds of lack of jurisdiction, a nonresident defendant must demonstrate that they were not domiciled in the state where the divorce was granted at the time the divorce action was initiated.

In family law, a court typically needs personal jurisdiction over both parties to issue a divorce decree that is recognized in other jurisdictions. Domicile is a key concept here; it relates to where a person has their permanent home and where they intend to return. If the nonresident defendant can prove that they were not domiciled in that state when the divorce was filed, they can argue that the court lacked the necessary jurisdiction to grant an ex parte divorce.

This reasoning emphasizes the importance of domicile over simply where one lives at a particular moment or the length of time one has spent in a state. While other factors, such as legal establishment or residency, might play a role in jurisdictional claims, the central focus is on domicile at the time of the divorce filing.
