What is the time limit for serving a summons after a complaint is filed, according to the rules?

The correct answer reflects the standard time limit set by the Federal Rules of Civil Procedure for serving a summons after a complaint has been filed. Specifically, Rule 4(m) states that if a defendant is not served within 90 days after the complaint is filed, the court must dismiss the action without prejudice against that defendant or order that service be made within a specified time.

This 90-day period allows the plaintiff sufficient time to locate the defendant and ensure that proper service of process is accomplished according to legal requirements. If service is not completed within this timeframe, the court's intervention serves as a mechanism to prevent indefinite delays in legal proceedings. Hence, understanding this timeframe is crucial for compliance with procedural rules in civil litigation, ensuring that defendants are timely informed of the claims against them.
