When a married person wants to file for divorce but is unable to locate their spouse to serve them with the petition or complaint (lawsuit) for divorce, the spouse filing for divorce may be able to provide the required legal notice of the divorce filing by publishing a notice at the courthouse or in a local newspaper. This is a special type of service of process known as service by publication, and to use it, the spouse filing for divorce usually must file an affidavit (sworn statement under oath) detailing the diligent efforts made to locate the missing spouse, stating that the missing spouse is not on active military duty, and identifying the missing spouse’s last known mailing address.

After the notice of service by publication is published in the required place and manner—at the courthouse, in the local newspaper, or in a certain legal publication—the missing spouse has a specified period of time in which to respond to the petition or complaint for divorce. If the missing spouse does not respond after service by publication the court may proceed with the divorce and enter a default judgment resolving all issues in the divorce, including the division of marital property. A divorce granted following service by publication is sometimes referred to as a publication divorce. If there are children involved in a publication divorce there may be additional requirements and challenges for the court to be able to issue orders regarding child custody and child support.

Laws regarding service by publication vary from state to state and are usually located in a state’s statutes or rules of civil procedure. The court must have personal jurisdiction over a missing spouse to be able to enter orders that impose personal obligations on the missing spouse, such as paying child support or marital debts. For these reasons a spouse whose estranged spouse is missing should generally talk to a family law attorney sooner than later.

In New Jersey, when a spouse wishes to file for divorce but cannot locate their partner, they may resort to 'service by publication.' This process involves the filing spouse making diligent efforts to find the missing spouse, including filing an affidavit with the court detailing these efforts, affirming the missing spouse is not on active military duty, and providing their last known address. If these efforts fail, the court may allow the filing spouse to publish a notice of the divorce action in a local newspaper or a legal publication. Once published, the missing spouse has a certain period to respond. If there is no response, the court may grant a default divorce judgment, which can include the division of property. However, when children are involved, there may be additional complexities in addressing custody and support. It's important to note that the court must have personal jurisdiction over the missing spouse to impose personal obligations such as child support. Due to the complexities and state-specific rules, it is advisable for the spouse seeking divorce to consult with a family law attorney to navigate the process properly.
