Definition
Service by publication is a method of serving legal process — most commonly a summons and complaint — on a defendant who cannot be located or who is absent from the jurisdiction, by publishing notice of the lawsuit in a designated newspaper or other approved public medium. It substitutes for personal delivery of process when personal service is impossible or impracticable after diligent effort.
Because service by publication does not reliably reach the defendant, courts treat it as a last resort. Statutes authorizing it typically require the plaintiff to demonstrate that other methods have been exhausted, to publish the notice a specified number of times over a defined period, and sometimes to mail a copy to the defendant's last known address simultaneously. The court acquires jurisdiction over the action, but the relief available may be limited: in most jurisdictions, a judgment obtained solely through publication service is valid only as to the res (property or status at issue) and does not support a personal money judgment against the defendant.

Common Confusion
Service by publication is frequently confused with substituted service and constructive service, and the three terms are sometimes used interchangeably in older sources.
Substituted service broadly refers to any method of serving process that substitutes for direct hand delivery — including service on a household member, a registered agent, or an authorized recipient. Service by publication is one species of substituted service, but not all substituted service is by publication.
Constructive service is the broader conceptual category: any service that gives legal notice without actual delivery to the person. Publication service is constructive, but constructive service also includes posting on a courthouse door or mailing under certain statutes. Researchers reading pre-twentieth-century materials should treat these terms as overlapping, not synonymous.

Core Elements
Courts and statutes generally require the following before publication service is valid:
1. DILIGENT SEARCH: The plaintiff must show genuine, documented efforts to locate the defendant through personal service. Failure to establish this can void the resulting judgment.
2. STATUTORY OR COURT AUTHORIZATION: Service by publication is purely a creature of statute and court rule. It has no common-law foundation. The applicable statute or rule controls which cases qualify, which publications are approved, how many times notice must run, and the interval between publications.
3. CONTENT OF NOTICE: The published notice must identify the parties, the court, the nature of the action, and the deadline for the defendant to respond. Defects in content may deprive the notice of legal effect.
4. PROOF OF PUBLICATION: The plaintiff must file an affidavit of publication — typically from the newspaper's publisher or clerk — confirming the dates and manner of publication. This becomes part of the record.
5. SUPPLEMENTAL MAILING (WHERE REQUIRED): Many modern statutes and court rules require mailing a copy of the summons and complaint to the defendant's last known address concurrent with publication. This requirement reflects due process developments after Mullane v. Central Hanover Bank & Trust Co. (1950).

Why It Matters in Research
This term sits at the intersection of procedural law and constitutional due process, and its meaning has been substantially reshaped by federal constitutional doctrine over the twentieth century.
The foundational shift came with Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306 (1950), in which the Supreme Court held that notice by publication alone is constitutionally inadequate when the defendant's address is known or reasonably ascertainable. Mullane did not abolish publication service but confined its constitutional legitimacy to situations where the defendant's identity or whereabouts are genuinely unknown. Researchers reading pre-1950 materials will find publication service treated as a robust and broadly available tool; post-Mullane sources reflect significantly narrowed permissible use.
A second line of development concerns in rem versus in personam jurisdiction. Pre-twentieth-century doctrine, rooted in Pennoyer v. Neff (1877), held that courts could exercise jurisdiction over property within the state through publication service, binding the res even without personal jurisdiction over the defendant. Researchers working in property, probate, or divorce records from the nineteenth and early twentieth centuries will encounter publication service used routinely to acquire jurisdiction over land titles, estates, and absent spouses. This remains permissible in limited form today, but the theoretical framework has shifted considerably under International Shoe Co. v. Washington (1945) and its progeny.
Jurisdictional variation is substantial in practice. State statutes differ on which case types permit publication service, which newspapers qualify as "newspapers of general circulation," how many insertions are required, and whether supplemental mailing is mandatory. Family law — particularly divorce and child custody — has historically been the most frequent arena for publication service, and many states have tightened requirements there specifically in response to due process concerns.
When researching historical court records, be aware that a judgment entered after publication service may carry a latent vulnerability: collateral attack on the adequacy of the search for the defendant, or on technical defects in the published notice, remained available long after judgment in many jurisdictions.

Historical Dictionary Support
Black's Law Dictionary defines service by publication as service of a summons or other process upon an absent or non-resident defendant by publishing the same as an advertisement in a designated newspaper, with such other efforts to give actual notice as the particular statute may prescribe. This formulation is compact and accurate for its era, capturing the essential mechanics without engaging the constitutional dimension that would later dominate the doctrine.
The definition's reference to "absent or non-resident defendant" reflects the Pennoyer-era framework, under which a defendant's physical absence from the jurisdiction was itself the trigger for publication service — a framing that has since given way to the more nuanced Mullane standard focused on whether the party's address is "reasonably ascertainable." Researchers relying solely on Black's traditional formulations risk applying an outdated threshold test.
Black's note that the statute controls "such other efforts" is a useful pointer to the multi-layered nature of modern publication service requirements, though it understates how extensively supplemental mailing and documented search obligations have been codified and constitutionally required since the mid-twentieth century. No historical dictionary in the Law Mind corpus provides a more expansive treatment; treatises on civil procedure and jurisdiction supply the fuller doctrinal history.

Jurisdictional Note
Every state has its own statute and court rules governing when publication service is authorized, what constitutes an approved publication, how many times notice must run, and whether mailing is required concurrently. Federal courts permit service by publication only when authorized by federal statute or, for certain in rem and quasi-in-rem actions, by the local state rules incorporated through the Federal Rules of Civil Procedure. Researchers should never assume that practice in one state transfers to another.
