Service by Publication When the Defendant Cannot Be Found

Service by publication is a court-approved way to notify a defendant of a lawsuit by printing a legal notice in a newspaper when that person cannot be located to receive the papers in hand. Courts treat it as a last resort because the U.S. Supreme Court has held that due process requires notice “reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections.”¹ A newspaper ad is far from ideal notice, and that is exactly why every step comes with strict requirements and why a judgment obtained this way is more vulnerable than one based on personal service.

When a Court Will Allow It

A judge approves publication only after the plaintiff shows that ordinary methods of delivery have failed despite a genuine effort to find the defendant. Common situations include a spouse who left with no forwarding address, a prior owner who cannot be located in a quiet title action, and a debtor who disappeared after default.

Just as important is when publication is off the table. If the plaintiff knows where the defendant lives, or could find out with minimal effort, the court will deny the request. The constitutional rule from Mullane is direct: when an address is known or reasonably discoverable, the plaintiff must use mail or personal delivery.¹ Asking for publication while sitting on the defendant’s actual address is a due process violation that can unravel the judgment later.

Federal Rule of Civil Procedure 4(e) does not list publication as a standalone federal option. It allows service by following the law of the state where the court sits or where service is made, so federal courts generally authorize publication by borrowing the state’s procedure.² One narrow federal carve-out exists for condemnation cases under Rule 71.1, which permits publication once a week for at least three successive weeks when personal service is not possible.³

Proving a Diligent Search

Before the court will consider publication, the plaintiff must prove they exhausted every reasonable way to find the defendant. Courts call this a “diligent search” or “diligent inquiry.” The results are documented in a sworn affidavit listing each step taken, the date it was performed, and what it turned up. Cutting corners here is the fastest way to have the judgment thrown out later.

A thorough search typically covers:

Government records such as DMV registrations, property tax rolls, voter registration, and vital records.
A postal inquiry for any forwarding address, often through a FOIA request to the U.S. Post Office.
Outreach to known relatives, former employers, and associates for leads on a current address.
Law enforcement arrest records, state corrections databases, and federal prison records.
A Defense Manpower Data Center check to determine whether the defendant is on active military duty.⁴
Occupational licensing boards and trade unions tied to the defendant’s known profession.
Social media, internet directory services, and public-records databases.

The affidavit has to be specific. “I searched the internet” will not do. Judges expect entries like “On March 4, 2026, I searched the Florida Department of Motor Vehicles database and found no record matching the defendant’s name and date of birth.” Every lead that went nowhere still needs to be documented, because the judge is evaluating the effort, not just the outcome. Filing a false affidavit carries criminal penalties, including fines and up to a year in prison for knowingly misrepresenting the search under oath.

A private investigator or skip-tracing service is not legally required, but it strengthens the affidavit. Costs generally run from around $100 for a basic database search to several thousand dollars for a full field investigation. Many attorneys consider it money well spent, because a weak diligent search is the most common basis for challenging the judgment later.

Filing the Motion and Drafting the Notice

With the affidavit in hand, the plaintiff files a Motion for Service by Publication asking the court for permission to proceed. The motion includes the defendant’s full name, the case number, a summary of the claims, and an explanation of why normal service failed. A proposed notice of action goes with it so the judge can review exactly what will appear in print.

The notice must give the defendant enough information to understand the case and respond. At a minimum, it identifies the court, the parties, the nature of the lawsuit, and a deadline to answer. It also warns that failing to respond will result in a default judgment granting what the plaintiff requested. Court filing fees vary, commonly $20 to $50 for the motion itself, with additional administrative costs depending on the jurisdiction.

Running the Notice and Filing Proof

Once the judge signs the order, the plaintiff delivers the notice to an approved newspaper of general circulation. Most courts keep a list of qualifying publications, and the paper usually must circulate in the county where the case is pending or where the defendant was last known to live. Publication fees commonly run from around $150 to $500 or more depending on the paper, the length of the notice, and local rates.

State rules generally require the notice to appear once a week for a set number of consecutive weeks. Four is the most common requirement; some states require three. Many jurisdictions also require the plaintiff to mail a copy of the notice to the defendant’s last known address before the final publication date. Skipping the mailing when a last known address exists, even an outdated one, can invalidate the entire service.

After the final printing, the newspaper issues an affidavit of publication (sometimes called proof of publication) confirming the notice ran on the specific dates ordered. The plaintiff files this with the court clerk. Without it, there is no evidence that publication occurred, and the case can stall or be dismissed. Filing proof also starts the defendant’s response clock.

The Military Service Affidavit

This step catches many plaintiffs off guard, and skipping it can destroy an otherwise valid judgment. Before any court enters a default judgment against a non-appearing defendant, federal law requires the plaintiff to file an affidavit stating whether the defendant is in the military.⁵ It applies in every civil case where the defendant has not appeared, from divorces to debt collection.

The affidavit must either confirm the defendant is not in service, confirm that they are, or state that the plaintiff was unable to determine the status. The Defense Manpower Data Center’s free online tool is built for this check and takes only minutes.⁴

The consequences of getting this wrong are serious. If the defendant is in military service, the court cannot enter a default until it appoints an attorney to represent them. If status is unknown, the court may require the plaintiff to post a bond covering any losses the defendant might suffer should the judgment later be overturned. Knowingly filing a false statement about military status is a federal crime punishable by fine and up to one year in prison.⁵

What the Judgment Can and Cannot Do

Once the response deadline passes with no filing from the defendant, the plaintiff can move for default. The response window usually runs about 20 to 30 days from the last publication date, though the exact period depends on the jurisdiction. The court reviews the motion to confirm every procedural step was followed. If anything is out of order, the judge can deny the default and require the plaintiff to start over.

A judgment obtained through publication carries a significant limit rooted in a principle the Supreme Court set out in 1878: service by publication gives the court power over property and legal status, but not over the defendant personally.⁶ A court can dissolve a marriage, clear a property title, or foreclose on a lien through publication service. What it generally cannot do is order the absent defendant to pay money damages, alimony, or child support, because those orders require personal jurisdiction. A plaintiff who needs a monetary award against a defendant served only by publication will likely find that part of the judgment unenforceable.

How These Judgments Get Challenged

Defendants who discover a judgment was entered against them through publication have several ways to fight back, and courts scrutinize these judgments more carefully than those based on personal service.

The strongest ground is defective notice. If the plaintiff knew the defendant’s address or could have discovered it with reasonable effort but chose publication anyway, the service violates due process under Mullane.¹ The Supreme Court has also held that when a party learns an attempt at notice failed, there is an obligation to take reasonable follow-up steps. A plaintiff who mailed a notice to a last known address, had it returned undeliverable, and did nothing further may have a due process problem.

Beyond constitutional grounds, most states allow a defendant to move to set aside a default on grounds of excusable neglect, accident, or mistake. A defendant who never learned about the lawsuit and can show a legitimate defense has a strong case for reopening. Timing matters: states impose deadlines for these motions, and some provide extended windows when service was by publication rather than in person. Under the SCRA, a servicemember whose military duties prevented them from defending can seek to reopen the judgment while on active duty or within 90 days after active duty ends, provided the service prejudiced their ability to defend and they have a valid defense.⁵

A judgment won through publication is only as strong as the diligent search behind it, and acting quickly matters on the other side as well: the longer a default stands unchallenged, the harder it becomes to undo, no matter how flawed the original service may have been.
