The Short-Form Complaint in an MDL: What a Plaintiff Actually Files

A short-form complaint is the pleading an individual plaintiff files in the MDL transferee court to adopt the master complaint by reference, rather than writing out a full complaint again. It is short because almost all of its substance has already been drafted by someone else: the plaintiff identifies themselves, names the product and the defendants, ticks the counts being adopted, and the case becomes operative on those allegations. Where a docket requires one, the deadline is set by a case management order — 30 days from transfer or removal is the figure used in the Bard implanted port catheter MDL — and missing it can put the case on a path to a show-cause order and dismissal.

What is a short-form complaint?

It is an abbreviated complaint, filed in the transferee district court by or for a single plaintiff, that incorporates the master complaint by reference and adds only the facts specific to that plaintiff.

The reason it exists is arithmetic. A mass tort docket is built from thousands of individual claims that share the same alleged defect, the same failure to warn and the same regulatory history. Drafting those common allegations once, in a master complaint, and letting each plaintiff adopt them is far cheaper than filing thousands of near-identical complaints. The master complaint is filed by plaintiffs leadership counsel; the short-form complaint is the one filing every individual plaintiff or their lawyer has to make.

The field list is stable across dockets because it comes from the same problem. Real forms — the District of Massachusetts GranuFlo form and the Eastern District of Pennsylvania Tylenol form, for instance — ask for these:

What the form asks	Why the pleading needs it
Plaintiff identity and capacity	Distinguishes a person suing for themselves from an administrator, executor or guardian suing for an estate
Spouse or loss-of-consortium plaintiff	Some dockets treat that as a separate plaintiff who needs their own filing
State of residence	Feeds diversity jurisdiction and the choice-of-law question
Home forum, or the district where venue would be proper absent direct filing	The district the case returns to after pretrial, and the record that direct filing was not treated as a venue determination
Defendants being sued	A check-off list from the master complaint; a defendant not named in the master complaint must be pleaded specifically
Counts adopted	The master complaint counts the plaintiff is adopting by reference
Case-specific facts	Anything the master complaint cannot supply — dates, exposure, injury, identifying records
Jury demand	Standard in the forms, and easy to forget when the document is templated

Why a master complaint is not a pleading on its own

This is the part that reads as a technicality and is not. A master complaint is an administrative device, not a filed pleading that starts a case, and courts say so expressly. In MDL 3081, the District of Arizona put it this way:

The Master Complaint shall be an “administrative convenience,” not an “operative pleading.” … The Master Complaint shall become operative by virtue of a Plaintiff filing a Short-Form Complaint that incorporates by reference the Master Complaint.

The order supports that proposition with Bell v. Publix Super Markets, Inc., 982 F.3d 468, 489–90 (7th Cir. 2020), Gelboim v. Bank of America Corp., 574 U.S. 405, 413 n.3 (2015), and In re Refrigerant Compressors Antitrust Litigation, 731 F.3d 586 (6th Cir. 2013). The practical consequence is that no individual claim in the docket stands on the master complaint. It stands on the short-form complaint that adopted it — which is why the document is procedural and consequential at the same time.

Who has to file one, and when is it due?

The duty covers every plaintiff whose case is in the docket under the order in question, which normally means four groups:

• cases the Judicial Panel on Multidistrict Litigation transferred under 28 U.S.C. § 1407, which includes the tag-along actions the Panel pulls in after the MDL is created — how a tag-along case reaches the docket sets out that route;
• cases filed directly in the transferee court, which skip the Panel entirely;
• cases removed from state court; and
• each plaintiff in a multi-plaintiff complaint, where the court has severed them so that every plaintiff files separately.

The deadline is whatever the case management order says. MDL 3081’s CMO No. 7 sets out the pattern cleanly: for cases already in the MDL on the order date, 30 days from the order; for cases transferred or removed after it, 30 days from transfer or removal.

Some dockets handle it differently. In the AFFF litigation, MDL 2873, Case Management Order No. 35 (filed August 15, 2025) allowed the short-form complaint only for cases filed inside a defined filing facilitation window and stated that use of the form would not be permitted after the window expired. A docket is not obliged to offer the device at all.

What happens if a plaintiff does not file one

Enforcement is graduated, and it is the part a claimant should understand before assuming the pleading is a formality.

In MDL 3081, the failure route runs through plaintiffs leadership rather than straight to the judge: co-lead counsel must advise a non-compliant plaintiff to file, and if the plaintiff still does not, counsel must notify the court, which may then issue a show-cause order why the case should not be dismissed.

The Tylenol MDL, MDL 2436, went further at the filing stage. Under its Case Management Order No. 7, an action filed directly into the MDL against the defendants named in the master complaint had to use the short-form complaint; a complaint filed without it was to be struck from the docket, and the plaintiff required to file a short-form complaint. The order also preserved the point that matters most to the plaintiff: the date of the original filing governs for the statute of limitations, not the date of the replacement pleading.

Does a short-form complaint waive anything?

Two directions of waiver get confused, and the orders separate them deliberately.

The defendant does not waive defenses by not answering. In MDL 3081, defendants are not required to answer short-form complaints at all. An entry of appearance, filed 30 days after the short-form complaint, is treated as a denial of every allegation in it and as incorporating the master answer and its defenses. The order adds that filing an entry of appearance in lieu of an answer does not waive any jurisdictional or service defense. The same order preserves Rule 12(b) objections where a defendant was not named in the master complaint and had to be pleaded separately.

Motion practice may be stayed so the pleading is not the fight. The AFFF order shows the other half: practice on a short-form complaint was stayed and could proceed only on leave of court, plaintiffs kept a right to amend to add the elements of a prima facie pleading before any motion practice, and a plaintiff could elect to file a traditional, non-short-form complaint before entering the bellwether pool or facing Rule 12 or Rule 8 challenges. A short-form complaint is designed to be a floor, not a waiver of a plaintiff’s ability to plead more.

Limitations do not restart. MDL 3081 states that, for limitations and repose, a plaintiff is deemed to have filed as of the first-filed complaint — not the master complaint and not the short-form complaint — unless the short-form complaint is the plaintiff’s first filing. A later, fuller complaint likewise relates back under Rule 15 in the transferee court.

What the “designated forum” line in the form is for

Direct filing has a consequence that surfaces later. If a case is filed directly into the MDL rather than transferred, it has not been transferred from anywhere, so when pretrial ends there is no transferor court to send it back to. MDL 3081 handles that by requiring the short-form complaint to identify a “designated forum,” and providing that a directly filed or removed case will be transferred there under 28 U.S.C. § 1404(a) or § 1406(a) — unless the parties waive the rule of Lexecon, Inc. v. Milberg Weiss Bershad Hynes & Lerach, 523 U.S. 26 (1998). Under Lexecon, a transferee court cannot try a transferred case without consent. The designated-forum answer in the short-form complaint is where a direct-filing plaintiff records where the case should go if pretrial does not resolve it. What happens when a case leaves an MDL covers that return trip in full.

How a short-form complaint differs from a fact sheet

They are often mentioned in the same breath and they are not the same instrument.

	Short-form complaint	Plaintiff fact sheet
Stage	Pleading	Discovery
Filed by	The plaintiff, once, in the transferee court	The plaintiff, once per case, under a court-ordered deadline
Sworn	No	Typically yes, under penalty of perjury
What it does	Adopts the master complaint and defines the claims	Gives the docket a census of exposure, product, use and injury
Consequence of missing it	Show-cause proceedings; in some dockets the complaint is struck	Notice, a cure period, then dismissal or a call docket

The pleading comes first; the record-gathering comes after. What a plaintiff fact sheet actually is explains the second stage.

How common is the device?

Common enough to be standard practice rather than an exception, though it is created docket by docket rather than by rule. The Panel’s own caseload is the context:

Measure (JPML report, October 1, 2026)	Figure
Active MDLs	162
Actions pending across all MDLs	204,977

Each of those dockets can adopt a master-complaint-and-short-form-complaint structure in a case management order, and most large ones do. Below are four orders that show how the terms vary — the deadline, whether the form is compulsory, and what happens to motion practice:

Docket	Court	Order	What it fixes
MDL 3081 — Bard implanted port catheter	D. Ariz.	CMO No. 7, 22 November 2023	30 days from the order, or from transfer or removal, to file; one complaint per severed plaintiff; limitations run from the first-filed complaint
MDL 2873 — Aqueous film-forming foams	D.S.C.	CMO No. 35, 15 August 2025 (ECF 7823)	Use limited to the filing window; practice stayed absent leave of court; a traditional complaint remains available before the bellwether pool
MDL 2436 — Tylenol (acetaminophen)	E.D. Pa.	CMO No. 7	Directly filed cases must use the short-form complaint; a complaint that does not is struck; the first filing date governs limitations
MDL 2428 — GranuFlo/Naturalyte dialysate	D. Mass.	Short-form complaint form	Adopts the master complaint by reference; check-off fields identify the plaintiff, the home forum and the district where venue would be proper

Frequently asked questions

What is a short-form complaint in an MDL? A short-form complaint is an abbreviated pleading that one plaintiff files in the MDL transferee court to adopt the master complaint by reference. It carries the case-specific facts the master complaint cannot — who the plaintiff is, where they live, the product or device at issue, the defendants being sued and the counts being adopted — and it is what makes the master complaint an operative pleading rather than a background document.

How long do I have to file a short-form complaint? It depends on the case management order in that docket, not on a rule of civil procedure. In the Bard implanted port catheter MDL, MDL 3081, Case Management Order No. 7 gave plaintiffs 30 days from the order for cases already in the docket and 30 days from transfer or removal for cases that arrived later. Some dockets instead tie permission to use a short-form complaint to a filing window, as the AFFF litigation did in CMO 35. Read the order in the specific docket.

What happens if a plaintiff does not file one? The consequence runs through plaintiffs leadership and then the court. In MDL 3081, plaintiffs co-lead counsel was directed to tell a non-compliant plaintiff to file, and if the plaintiff still did not, to report it so the court could issue a show-cause order why the case should not be dismissed. In the Tylenol MDL, MDL 2436, a directly filed complaint that did not use the short-form complaint was struck from the docket, and the plaintiff was required to file one.

Does a short-form complaint restart the statute of limitations? No. Courts treat it as a substitute for the pleading already on file, not as a new action. MDL 3081 provides that, for limitations and repose, a plaintiff is deemed to have filed as of the first-filed complaint, not the master complaint or the short-form complaint, unless the short-form complaint is that plaintiffs first filing. MDL 2436 says the same about a complaint that is struck and refiled.

Is a short-form complaint the same as a plaintiff fact sheet? No. They come at different stages and do different work. A short-form complaint is a pleading: it adopts the master complaint and defines the claims in the case. A plaintiff fact sheet is discovery: a court-ordered questionnaire, answered under penalty of perjury, that gives the docket a census of exposures, products and injuries. The pleading comes first.

This is not legal advice

This describes how a pleading device used in multidistrict litigation works. It cannot tell you whether a short-form complaint has been filed in your case, what deadline applies to it, or whether your claim is timely. Those answers are in the docket and in the order that governs it, and only a lawyer reviewing that file can give them.
