A defense available to a defendant asserting that the plaintiff failed to effect service of the summons and complaint in the manner required by Rule 4. The defense focuses on defects in the manner or method of delivery rather than defects in the form of the summons itself. A successful motion results in dismissal without prejudice unless the plaintiff cures the defect.
Ryan Roberts filed suit against Radiant Technologies in federal court. His process server handed the summons and complaint to the defendant's adult sister who was visiting the defendant's home for a weekend. The sister did not reside at the address. Radiant Technologies moved to dismiss under Rule 12(b)(5). The court granted the motion because the sister lacked the required residency status for substituted service.
Raphael Rivera sued Roger Ramirez for breach of contract. The process server delivered the papers to the doorman of Ramirez's apartment building. The doorman accepted packages and messages for residents but did not live in the building. Ramirez moved to dismiss under Rule 12(b)(5). The court denied the motion after finding that the doorman's regular role satisfied the spirit of the residency requirement for substituted service.

A Rule 12(b)(4) motion challenges defects in the form or content of the summons itself. A Rule 12(b)(5) motion challenges the manner in which the summons and complaint were delivered to the defendant. The essay question on jurisdiction and venue illustrates that objections to who received the papers fall under Rule 12(b)(5) while defects in the summons text fall under Rule 12(b)(4).

Some courts have relaxed the literal residency requirement when the recipient regularly performs duties that bring process to the defendant's attention. The Civil Procedure Examples and Explanations excerpt cites Churchill v. Barach as an instance where service on a doorman satisfied the rule despite the doorman not residing at the premises.
