The Mailed Summons and the Running Service Clock
Your firm filed a diversity personal-injury complaint in federal district court on March 10, 2025. The client was injured on March 15, 2023, and the applicable state limitations period is two years, so the complaint was filed nine days before the limitations period expired. The defendant is a regional grocery chain with a registered agent in the state. The litigation paralegal mailed the summons and complaint by certified mail to the store where the fall occurred, not to the registered agent. The certified-mail receipt shows delivery on March 14, 2025, to a store manager. No waiver of service was requested, and no process server was engaged. On June 24, 2025, the defendant moves to dismiss under Federal Rule of Civil Procedure 12(b)(5) for insufficient service and untimely service under Rule 4(m). The supervising attorney asks you to reconstruct the timeline and recommend a response.
1. Calculate the Rule 4(m) service deadline and assess whether the March 14 delivery was effective service on the corporation.

Rule 6(a) excludes the day of the event, so count from March 11. The 90th day is June 8, 2025. Because June 8 is a Sunday, Rule 6(a)(1)(C) rolls the deadline to Monday, June 9. The March 14 delivery was within that period, so timeliness is not the main problem; effectiveness is. Under Rule 4(h), a corporation must be served by delivering to an officer, a managing or general agent, or another agent authorized by appointment or law, or pursuant to state law. A store manager may be a managing agent for store operations, but that is fact-dependent and risky; the registered agent was the safe target. Certified mail may be authorized by state law, but mailing to the store rather than the registered agent does not establish compliance. Also, no waiver under Rule 4(d) was requested. Conclusion: service was probably insufficient even though delivered within 90 days.
2. What arguments and corrective steps should the firm take in response to the motion?

The firm should not rely on good cause alone. The file shows no attempt to locate the registered agent, so good cause is weak. Instead, immediately serve the registered agent properly, file proof of service, and ask the court to extend time under Rule 4(m) or to quash rather than dismiss. Argue that the defendant had actual notice through its store manager, that the defect is curable, and that dismissal would be effectively with prejudice because the two-year limitations period expired on March 15, 2025. Check whether the defendant's motion waived any defense; a 12(b)(5) motion preserves it, so do not assume waiver. Also verify whether the store manager qualifies as a managing agent; if so, service may be valid. Prepare a short declaration explaining the mailing, the receipt, and the prompt corrective service. Avoid blaming the client. If the court dismisses without prejudice, the firm must evaluate a malpractice exposure and notify its carrier.
3. Identify two office procedures that would prevent a recurrence.

Adopt a service checklist that identifies the entity type, verifies the registered agent through the secretary of state, and selects an authorized method. Calendar the 90-day Rule 4(m) deadline at filing and set 30-, 60-, and 75-day ticklers. Require a second person to review the proof of service before the deadline. The checklist should also document whether a Rule 4(d) waiver was requested and, if so, when the defendant responded. For corporate defendants, the file should include the secretary of state record showing the registered agent and the exact address used. This prevents the common error of serving a local store when the legal entity must be served through its registered agent.
