Accuracy update — reviewed August 7, 2026. Modern service is governed by constitutions, statutes, and court rules—not by a universal conflict between “common-law service” and “constructive service.” Personal delivery is often preferred, but other authorized methods can be valid when their requirements and due process are satisfied.
The constitutional baseline
Mullane v. Central Hanover Bank & Trust Co., 339 U.S. 306 (1950), requires notice reasonably calculated, under all the circumstances, to inform interested parties and give them an opportunity to object. Due process does not require actual notice in every case, but the chosen method must be reasonable in light of what the sender knows.
Common methods
- Personal service: delivery directly to the person under the applicable rule.
- Substitute service: delivery at a dwelling, to an authorized agent, or another method the rule permits.
- Mail or certified mail: valid in some proceedings and jurisdictions when statutory steps are followed.
- Electronic service: sometimes permitted by rule, court order, or consent, especially after a party has appeared.
- Publication: generally a last-resort method when the person cannot be located after the diligence the law requires.
Publication requires a fact-specific inquiry
Publication is not automatically invalid, and it is not automatically sufficient. A court may examine whether the serving party used reasonably available information, searched the sources required by law, documented efforts, and sought authorization properly. When mailed notice is returned unclaimed and additional practical steps are available, Jones v. Flowers, 547 U.S. 220 (2006), requires reasonable follow-up before the government takes property.
Do not confuse rule defects with constitutional defects
A technical violation of a service rule may justify relief under that rule without necessarily amounting to a due-process violation. Conversely, formal compliance may be constitutionally inadequate if the method was not reasonable under known circumstances. Actual notice can matter, but it does not automatically cure every jurisdictional defect. Waiver and preservation rules also vary.
Audit the evidence
- Identify the governing rule on the filing date.
- Collect summonses, returns, affidavits, tracking, publication notices, and address records.
- Document what the serving party knew and what searches were performed.
- Determine when and how any objection was raised.
- Check the remedy and deadline under current controlling authority.
