A class action is one representative lawsuit that covers many people with a shared outcome. Multidistrict litigation, or MDL, keeps each federal lawsuit separate but coordinates pretrial work before one judge.
That difference controls what you must do. A class member often waits for a claim form. An MDL plaintiff needs an individual case and lawyer from the start.

How does a class action cover so many people?
A class action lets named plaintiffs sue for everyone with similar claims. The court must find numerosity, commonality, typicality, and adequate representation before the class can proceed. Under standards described by the Cornell Law School Legal Information Institute in the Federal Rule 23 requirements, the court must also certify the class.
Certification sets the boundaries for relief. If the case settles or wins, covered members generally share the same result. Members in many damages cases are bound unless they formally opt out.
How does an MDL pull cases together?
An MDL moves federal cases with shared factual questions to one district for coordinated pretrial work. Under law described by the Cornell Law School Legal Information Institute in the Section 1407 statute text, the transfer serves party convenience and efficient handling. The seven-member Judicial Panel on Multidistrict Litigation selects the judge and court.
The Panel seeks to avoid duplicate discovery, prevent conflicting pretrial rulings, and save resources. An MDL is not a type of class action, according to the U.S. District Court for the District of Kansas. Class actions with shared facts can join an MDL alongside individual cases without changing that distinction.
Do you need to file your own case?
Participation works differently in each path. A class member often does nothing until notice and a claim form arrive.
The Congressional Research Service observes in its September 2024 class action explainer that damages class members are commonly bound unless they exclude themselves, while MDL plaintiffs must file or retain their own suits. In practice the choice looks like this: An MDL plaintiff keeps an individual case and lawyer. Centralization covers discovery and pretrial steps, not passive membership.
- In a class action, check class membership, deadlines, and opt-out rights before filing alone.
- In an MDL, hire counsel, file your own federal case or retain one, and submit required plaintiff records.
What does the ending look like for you?
A class action aims toward one uniform resolution for the certified group. Eligible members claim through the same settlement fund or judgment process.
An MDL preserves individualized resolution. Each transferred case remains separate during coordinated work, and cases not resolved centrally return to their home districts for trial. Track whether your notice names a class settlement or an MDL case number, then save the deadline notice and confirm with counsel whether you must file individually to preserve payment rights.
