Caption
Complete case caption with court name, docket number, parties, and contact information for counsel so the filing is accepted and routed correctly.
A well-prepared motion preserves meritorious claims, corrects pleading errors, and adds parties discovered later while minimizing the risk of dismissal or sanctions under FRCP 15 or comparable state rules.
The motion is most often prepared by licensed litigators but is also used by experienced in-house counsel and some pro se plaintiffs.
Regardless of who prepares it, the motion should include a proposed amended complaint, a legal memorandum addressing Rule 15 factors, and a certificate of service.
Civil litigators preparing motions to preserve claims or add parties after discovery use Rule 15 analysis and cite case law; they include proposed redlines and a proposed amended complaint with exhibits.
Self-represented litigants must follow local filing and service rules, include a clear proposed amended complaint, and may need help meeting procedural requirements to avoid dismissal for improper formatting or insufficient service.
