Class action lawyer marketing is the work of finding class members and representative plaintiffs, and it runs on different mechanics from the campaigns most consumer practices run.
It sits at the complex end of personal injury lawyer marketing, because consumer class work grows out of injury, consumer and employment practices, but a class campaign is not a volume play: it needs one or a few representative plaintiffs whose claims can stand in for a larger group, and, once a settlement exists, class members who file claims.
The two age differently: demand for a representative plaintiff peaks before filing, while claimant outreach sits downstream of a settlement, which Federal Rule of Civil Procedure 23(e) says needs the court's approval before a class, or a proposed class settlement, is settled, dismissed or compromised.
What class action marketing has to produce
Class action marketing is recruitment for a lawsuit: the unit of success is a named representative plaintiff or a class member who files a claim, not a signed case in the ordinary sense.
The scale context is jurisdictional: under the Class Action Fairness Act, federal district courts have original jurisdiction over class actions with more than $5,000,000 in controversy (claims added together) and minimal diversity, where the class has at least 100 members in total, under 28 U.S.C. §1332(d); its exceptions, including local controversy and home state provisions, are not covered here.
Mass torts are the better-known cousin: many individual claims, coordinated rather than representative, usually riding an MDL docket; that playbook, including lead buying and the drug and device ad statutes, is in mass tort marketing.

Where demand sits: the FY 2025 federal numbers
Per the U.S. Courts' Judicial Business 2025 report, federal civil filings are down 12% since 2021, mostly because of fewer personal injury and product liability cases, while filings grew in civil rights, intellectual property, contract actions, real property, TCPA, arbitration, FOIA and federal tax cases.
The injury decline is largely an MDL wind-down rather than fewer harms: pending federal civil cases fell 19% to 432,923 in FY 2025, most of the drop coming from personal injury and product liability cases in the Northern District of Florida, where the 3M earplug MDL cases closed.
The fastest-growing FY 2025 types read like class action feedstock: TCPA cases rose 78% to 2,367, consumer credit rose 12% to 9,574, civil rights rose 15% to 46,854, and Fair Labor Standards Act cases fell 6% to 4,810.
Federal case types that grew, FY 2025
The MDL docket is where class work gets confused with mass tort work: in FY 2025 the Judicial Panel on Multidistrict Litigation acted on 37,735 civil actions, created 19 new MDL dockets, and had 197,118 actions pending at year end.
MDLs are not class actions, although some include them, and the two recruit different people.
What a class action lead actually is
A lead here is either a prospective representative plaintiff, screened on strength and fit, or a claimant filing into an existing settlement; the first is scarce and specific, the second is closer to processing than persuasion.
The volume math inverts a DUI campaign: one signed representative plaintiff can carry a filing, so cost per lead means little and cost per signed engagement is the number that matters.
Buying leads raises the questions any bought lead does; the ABA's position on paying generators is in lead generation ethics for lawyers.
Class action advertising: notice is not advertising
The distinction that catches firms is court-ordered notice versus the firm's own advertising: for a Rule 23(b)(3) class, the court must direct the best notice that is practicable, including individual notice to identifiable members, by U.S. mail, electronic means or other appropriate means.
Notice is the court's mechanism, run under its direction; a firm's own advertising to find class members is a different activity, and bar advertising rules still apply to it.
The framework underneath is the same as for any legal ad; Model Rules 7.1 to 7.3 are covered in lawyer advertising rules, and ABA Model Rules bind no one until a state adopts them, so your state's version controls.
One piece matters most here: ABA Model Rule 7.3, as the ABA publishes it, defines solicitation as a lawyer-initiated communication to a specific person known to need legal services; state versions differ significantly, and some are stricter about contacting accident and disaster victims.
States also write statutes aimed at specific legal ads: Texas Government Code chapter 81, subchapter J, effective September 1, 2019, applies to television advertisements that promote legal services or solicit clients; it is written for TV, so it does not reach online ads on its own terms.
Texting is the other surface to check: TCPA suits rose 78% in FY 2025, with no stated cause given, and the requirements a texting campaign runs into are in TCPA rules for law firms.
- Decide what the campaign recruits for: a named representative plaintiff, or claimants filing into an approved settlement. Different products, different volumes.
- Pick the case type from filing data: civil rights, TCPA and consumer credit filings grew in FY 2025, FLSA cases fell.
- Put the fee terms in writing before intake opens: ABA Model Rule 1.5(c) requires a signed written agreement stating the percentage and expense handling.
- Judge the spend by consultations booked and engagements signed, not impressions or form fills.
- Ask your state bar's ethics counsel how its advertising rules treat ads aimed at finding class members.
How class action fees shape the marketing math
In an individual contingency practice the fee comes out of the client's recovery; in a certified class action, the court may award reasonable attorney's fees and nontaxable costs authorized by law or by agreement, on a Rule 54(d)(2) motion.
No typical class counsel percentage is published, and this page will not invent one; the percentage in any engagement is what a signed agreement states.
The writing requirement travels with the practice: ABA Model Rule 1.5(c) allows contingent fees except where prohibited and requires a written agreement signed by the client, stating the percentage on settlement, trial or appeal and how expenses are handled; state versions vary.
That fee structure is why class work punishes borrowed benchmarks: no published benchmark exists for a law firm's consultation-to-signed-case rate, so use your own numbers, and cost per signed case shows the arithmetic.
Before running advertising aimed at class members, confirm with your state bar's ethics counsel or an ethics lawyer; the rules above are descriptions, not advice, and your state's version controls.
Frequently asked questions
Is a class action the same as an MDL?
No. An MDL coordinates individual cases for pretrial work before one judge, while a class action litigates representative claims on behalf of a class. In FY 2025, 197,118 actions were pending in MDLs per the Judicial Panel on Multidistrict Litigation, and MDLs are not class actions, although some include them.
How many class members does a class action need?
For federal jurisdiction under the Class Action Fairness Act, the class must have at least 100 members in total, with more than $5,000,000 in controversy and minimal diversity, under 28 U.S.C. §1332(d). The statute has exceptions this summary does not cover.
How do class action lawyers get paid?
In a certified class action, the court may award reasonable attorney's fees on a motion under Rule 54(d)(2), per Federal Rule of Civil Procedure 23. No typical percentage is published, and a contingent fee needs a written agreement signed by the client under ABA Model Rule 1.5(c), with your state's version controlling.
How do law firms find class members?
Two different routes exist. In a Rule 23(b)(3) class, the court directs the best notice that is practicable, by U.S. mail, electronic means or other appropriate means; a firm's own advertising to find class members is separate, and bar advertising rules still apply to it.
Are class action ads treated differently from other lawyer ads?
The ABA Model Rules supply the template and each state adopts its own version, so a few states have rules written for specific legal ads. Texas Government Code chapter 81, subchapter J, effective September 1, 2019, applies to television advertisements that promote legal services or solicit clients; it is written for TV and does not reach online ads on its own terms.
