Class Action Complaint

Drafts a court-ready class action complaint that survives a 12(b)(6) motion and lays the groundwork for Rule 23 certification.

Prerequisites

Collect before drafting:

1. Named plaintiff facts — individual harm, standing, timeline, no conflicts with putative class
2. Defendant identification — corporate structure, registered agents, principal place of business
3. Class-wide conduct — documents/policies/data showing systematic wrongdoing
4. Proposed class definition — objective inclusion/exclusion criteria
5. Jurisdictional basis — federal question (§ 1331), CAFA (§ 1332(d)), or state court
6. Case files — contracts, correspondence, expert reports, damages data

Complaint Structure

Caption: Court name/division; "[Named Plaintiff], on behalf of [himself/herself/themselves] and all others similarly situated"; defendant(s); "CLASS ACTION COMPLAINT"; jury demand if applicable.

#	Section	Content
I	Introduction	2–3 ¶¶: parties, wrongdoing summary, class-wide harm
II	Parties	Named plaintiff standing + defendant corporate details
III	Jurisdiction & Venue	Statutory basis, amount in controversy, CAFA threshold ($5M+, 100+ members, minimal diversity)
IV	Factual Allegations	Chronological narrative with dates, amounts, document quotes
V	Class Allegations	Rule 23(a) + 23(b) elements per checklist below
VI	Causes of Action	Each count as separate section
VII	Prayer for Relief	Itemized demands

Rule 23 Checklist

Draft each element as a subsection with factual support.

23(a) — All four required

• Numerosity — Joinder impracticable. Allege estimated size with evidentiary basis. Generally 40+ suffices.
• Commonality — Common questions of law/fact driven by defendant's uniform conduct. Per Wal-Mart v. Dukes, 564 U.S. 338 (2011): common contention whose resolution drives each member's claim.
• Typicality — Named plaintiff's claims arise from same conduct/theories as class. Flag unique defenses.
