Removal and Remand: Moving a Case Between State and Federal Court

Removal moves a civil action from state court to the federal district court for the district and division embracing the place where the state action is pending. The authority is 28 U.S.C. §1441, the procedure is in §1446, and the route back is §1447.

Only a defendant may remove, and only when the federal court would have had original jurisdiction over the action. No motion is required and no permission is sought: filing the notice, giving written notice to all adverse parties, and filing a copy with the state court clerk effects the removal, and the state court proceeds no further unless and until the case is remanded.

The two ordinary grounds

Federal question. The case must arise under federal law on the face of a well-pleaded complaint. A federal defense does not create removal jurisdiction, and neither does a counterclaim raising federal law. This trips up defendants regularly: the strongest federal argument in the case may be entirely irrelevant to whether it can be removed.

Diversity. There must be complete diversity — no plaintiff sharing citizenship with any defendant — and an amount in controversy exceeding $75,000, exclusive of interest and costs, under the threshold in force as of mid-2026. Citizenship is determined by rules that vary by entity form: a corporation is a citizen of its state of incorporation and of its principal place of business, while the citizenship of an unincorporated entity such as an LLC or partnership generally traces to each of its members or partners. That tracing is where diversity removals most often fail, because a single member in the plaintiff's state destroys jurisdiction.

Where the initial pleading does not state a sum — because state practice forbids a specific demand or permits recovery beyond it — the notice of removal may assert the amount in controversy, and removal is proper if the district court finds by a preponderance of the evidence that the threshold is exceeded. Statutory schemes including class-action removal have their own rules, which differ on consent, the forum-defendant limit, and appellate review; confirm which regime applies before assuming the general rules govern.

The clocks, and why they are the whole game

1. Day 0 — receipt of the initial pleading

   The 30-day period runs from receipt by the defendant, through service or otherwise, of a copy of the initial pleading setting out the claim for relief — or from service of the summons if the pleading has been filed in court and is not required to be served, whichever period is shorter.

2. Within 30 days of that defendant's service

   Each defendant has its own 30-day period measured from its own service. A later-served defendant may remove within its window, and earlier-served defendants may consent to that removal even if their own period has run.

3. On receipt of an "other paper"

   If the case was not removable as pleaded, a notice may be filed within 30 days after receipt of an amended pleading, motion, order, or other paper from which it may first be ascertained that the case is or has become removable.

4. One year after commencement

   A diversity case generally may not be removed on that later-discovered basis more than one year after the action commenced, unless the court finds the plaintiff acted in bad faith to prevent removal.

5. Within 30 days of the notice of removal

   A motion to remand on any defect other than lack of subject-matter jurisdiction must be filed in this window. Miss it and the defect is waived.

6. Any time before final judgment

   If it appears the district court lacks subject-matter jurisdiction, the case must be remanded — on motion or on the court's own initiative.

Deadline discipline: the 30-day clock is not extended by a scheduling stipulation, by a pending state-court motion, or by the parties' agreement. Calendar it from the date of receipt shown on the return of service, and treat any discussion about extending it as a discussion about a deadline that cannot be moved.

Two limits that defeat sound removals

The forum-defendant rule. A civil action otherwise removable solely on the basis of diversity may not be removed if any party in interest properly joined and served as a defendant is a citizen of the state in which the action was brought. The logic is straightforward: diversity jurisdiction exists to protect out-of-state parties from local bias, and a defendant sued at home needs no such protection. Note the qualifier — "properly joined and served" — which has produced a substantial body of litigation about defendants named but not yet served.

Unanimity. When removal rests on §1441(a), all defendants who have been properly joined and served must join in or consent to the removal. A single non-consenting defendant defeats it. Consent should be documented in a form the district accepts, whether by signature on the notice or by a separately filed statement, and the removing party should say expressly which defendants had been served at the time.

A related trap is fraudulent joinder. Where a plaintiff joins a non-diverse defendant against whom no plausible claim exists, a removing defendant may argue that citizenship should be disregarded. The showing required is demanding, and courts resolve doubts in favor of remand. Do not build a removal strategy on it without evidence.

Filing mechanics

• A notice of removal signed under Rule 11, containing a short and plain statement of the grounds for removal.
• A copy of all process, pleadings, and orders served upon the removing defendant or defendants in the state action.
• Consent from every properly joined and served defendant, in the district's accepted form.
• An allegation of each party's citizenship stated with the specificity the entity form requires — not simply "a Delaware company".
• Written notice of the filing to all adverse parties.
• A copy of the notice filed with the clerk of the state court, which effects the removal.
• Any local civil cover sheet, corporate disclosure statement, and related-case filing the district requires.

Because the notice is signed under Rule 11, the certifications about legal and factual contentions apply to the jurisdictional allegations in it. Our brief on Rule 11 sanctions and the safe harbour explains what that signature commits the signer to. After removal, the Federal Rules govern going forward, which changes pleading standards, disclosure obligations, and the proportionality analysis applied to discovery.

Remand, fees, and the reviewability rule

Section 1447(c) sets two different regimes, and the distinction between them is the single most useful thing to know in this area. A motion to remand on the basis of any defect other than lack of subject-matter jurisdiction must be made within 30 days after the notice of removal is filed. Procedural defects — a late notice, a missing consent, a forum-defendant problem — sit in that category and are waived if not raised in time. By contrast, if at any time before final judgment it appears the district court lacks subject-matter jurisdiction, the case shall be remanded. That defect cannot be waived, cured by consent, or forfeited by delay.

An order remanding the case may require payment of just costs and any actual expenses, including attorney's fees, incurred as a result of the removal. The Supreme Court held in its 2005 decision in Martin v. Franklin Capital Corp. that, absent unusual circumstances, fees should be awarded only where the removing party lacked an objectively reasonable basis for seeking removal. A removal that is wrong but defensible ordinarily does not produce a fee award.

Then comes the asymmetry. Section 1447(d) provides that an order remanding a case to the state court from which it was removed is not reviewable on appeal or otherwise, with exceptions for cases removed under the federal-officer and civil-rights removal statutes. Some statutory schemes, including class-action removal, supply their own discretionary appellate review. The practical effect is that a defendant gets one real chance to establish federal jurisdiction, and an erroneous remand usually stands.

Verify before relying: whether the amount in controversy is satisfied, how a particular entity's citizenship is determined, and how the forum-defendant rule applies to unserved defendants are all questions on which circuits and districts have taken different positions. Confirm the rule in the specific circuit before the 30 days run, because there is no second attempt.

Questions the desk gets

What happens to orders the state court already entered?

They remain in effect after removal until the district court modifies or dissolves them. A state-court injunction or discovery order does not evaporate on removal; the federal court inherits the case in its existing posture. Because the standards for injunctive relief differ between systems, a party may promptly move to modify — see our brief on temporary restraining orders and preliminary injunctions for what that motion has to show.

Can a plaintiff remove its own case?

No. The statute permits removal by the defendant or defendants, and the Supreme Court confirmed in 2019 that a third-party counterclaim defendant is not a "defendant" who may remove under the general removal statute. A plaintiff who wants a federal forum has to choose one at filing.

Does removal waive objections to personal jurisdiction or venue?

Removal itself does not waive a defense of lack of personal jurisdiction, which is preserved by raising it properly in the federal case under the ordinary waiver rules. Venue works differently after removal: the removal statute fixes the district, and objections to the state-court venue do not carry over in the same form. Our brief on personal jurisdiction and venue addresses both.

What if the plaintiff amends to add a non-diverse defendant after removal?

The court has discretion to deny joinder or to permit it and remand. The inquiry usually considers whether the amendment is intended primarily to defeat federal jurisdiction, whether the plaintiff was dilatory, whether denial would prejudice the plaintiff, and any other equities. This is one of the few post-removal moments that can send a properly removed case back.

Does removal affect a settlement already in progress?

Not the substance of it, but it changes which court will enforce it. A federal court's ability to enforce a settlement after dismissal depends on whether the dismissal order retains jurisdiction or incorporates the terms; our brief on settlement agreements and releases explains how that is preserved.

What to do next

For a defendant, treat the first day of the case as the removal analysis. Confirm the citizenship of every party and every member of every unincorporated entity, calculate the amount in controversy with a documented basis, identify who has been served, and obtain consents in writing. Thirty days sounds generous and is not, particularly where consents must be gathered from co-defendants who have their own counsel.

For a plaintiff resisting removal, separate the arguments by clock. Procedural defects go in a motion filed within 30 days of the notice, with the deficiency identified precisely. Jurisdictional defects can be raised later but should be raised early anyway, because the cost of litigating in the wrong forum is not recoverable. Where a fee request is warranted, address the objective-reasonableness standard directly rather than arguing that the removal was simply wrong.

The statutory text is short enough to read in full before any deadline is calculated — see §1446 and §1447.
