Summary. Removal is a procedural right with unforgiving deadlines, and the party that gets it wrong loses a forum choice worth more than most substantive rulings. This guide covers the jurisdictional bases and their requirements, then the mechanics: the thirty-day clock and when it starts, the rule of unanimity, the forum defendant rule and snap removal, and what the notice must contain. It then covers remand — jurisdictional defects raisable at any time versus procedural defects waived after thirty days, the one-year limitation and its bad faith exception, and fee awards — followed by fraudulent joinder, CAFA, complete preemption, and strategy.

A products case is filed in state court against a manufacturer and a local retailer. The manufacturer is a Delaware corporation headquartered in Michigan; the plaintiff and the retailer are both in Missouri.

The manufacturer's counsel sees the case as removable on a fraudulent joinder theory — the retailer sold a sealed product, did nothing wrong, and is protected by the state's innocent seller statute. Counsel is right about the merits.

Counsel is served on March 3. The retailer is served on March 19. Counsel files a notice of removal on April 14, joined by the retailer, asserting that the retailer's citizenship should be disregarded.

The case is remanded — not on the fraudulent joinder question, which the court never reaches, but because the notice was filed 42 days after the manufacturer was served. Under the removing defendant's own clock, it was 12 days late.

Whether the later-served retailer's 30 days would have supplied a fresh window under § 1446(b)(2) is a question the court did not need to answer, because the manufacturer had already blown its own deadline and the earlier-served defendant's failure to remove within its period is what the court examined.

The forum choice — which for a products case in that venue was worth a great deal — was lost to a calendar. This is the ordinary shape of removal error.

The bases for removal

Section 1441(a) permits removal of any civil action brought in state court of which the district courts have original jurisdiction, to the district and division embracing the place where the action is pending.

Diversity jurisdiction, 28 U.S.C. § 1332(a):

  • Complete diversity — no plaintiff may share citizenship with any defendant. Strawbridge v. Curtiss, 7 U.S. 267 (1806), and unchanged since.
  • Amount in controversy exceeding $75,000, exclusive of interest and costs.
  • Citizenship determined at the time of filing and at the time of removal.

Citizenship rules that decide cases:

  • Individuals — domicile: residence plus intent to remain indefinitely.
  • Corporations — the state of incorporation and the state of the principal place of business, which under Hertz Corp. v. Friend, 559 U.S. 77 (2010), is the nerve center where high-level officers direct, control, and coordinate activities.
  • LLCs, partnerships, and unincorporated associations — the citizenship of every member or partner, traced through every tier to natural persons or corporations. This is the most common defect in removal papers, and courts routinely order jurisdictional discovery or remand where the chain is not pleaded.
  • Trusts — a traditional trust takes the trustee's citizenship; a business trust takes the citizenship of its members, Americold Realty Trust v. ConAgra Foods, Inc., 577 U.S. 378 (2016).
  • Estates and representatives — the legal representative of a decedent's estate takes the decedent's citizenship, § 1332(c)(2).
  • Aliens — an alien admitted for permanent residence and domiciled in the same state as an opposing party defeats jurisdiction, § 1332(a).

The amount in controversy. Dart Cherokee Basin Operating Co. v. Owens, 574 U.S. 81 (2014), holds that a notice of removal need include only a plausible allegation that the amount exceeds the threshold; evidence is required only when the plaintiff contests it or the court questions it. On contest, the removing party must establish the amount by a preponderance of the evidence.

Where the complaint does not state an amount, use: the damages categories pleaded and their computation; medical bills or repair estimates; the contract at issue; the value of injunctive relief (measured by its value to the plaintiff or, in some circuits, the cost to the defendant); attorney's fees, where recoverable by statute or contract; and punitive damages where available. Do not aggregate separate plaintiffs' claims unless they assert a single title or right in common.

Federal question jurisdiction, 28 U.S.C. § 1331, governed by the well-pleaded complaint rule: federal jurisdiction exists only where a federal question appears on the face of the plaintiff's properly pleaded complaint. A federal defense — including preemption asserted as a defense — does not create removal jurisdiction, Caterpillar Inc. v. Williams, 482 U.S. 386 (1987).

Three exceptions:

Other removal statutes:

  • § 1442 — federal officers and agencies, and persons acting under them, including government contractors. Unlike ordinary removal, it does not require unanimity, is not subject to the forum defendant rule, and permits removal of the entire case. It requires a colorable federal defense.
  • § 1443 — civil rights removal, extremely narrow.
  • § 1452 — claims related to a bankruptcy case, with its own equitable remand provisions.
  • § 1454 — patent and plant variety protection claims, removable by any party.
  • CAFA, § 1453, discussed below.

The mechanics and the deadlines

Section 1446(b)(1) — the notice of removal must be filed within 30 days after receipt by the defendant, through service or otherwise, of the initial pleading — or within 30 days after service of the summons if the initial pleading has been filed and is not required to be served.

Murphy Bros., Inc. v. Michetti Pipe Stringing, Inc., 526 U.S. 344 (1999), holds that the period runs from formal service, not from informal receipt of a courtesy copy. A defendant that receives an unserved copy of the complaint by email has not started its clock.

Section 1446(b)(3) — where the initial pleading is not removable, the 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 removable. The document must make removability ascertainable; a defendant's own investigation generally does not start the clock, and several circuits require the paper to be unequivocally clear.

Common "other papers": an amended complaint adding a federal claim or dropping a non-diverse defendant; a settlement demand exceeding the threshold; a discovery response revealing damages; a deposition transcript; a dismissal of the non-diverse party; and a plaintiff's stipulation.

The later-served defendant rule, § 1446(b)(2)(B)-(C). Each defendant has 30 days from its own service. A later-served defendant may remove within its own 30 days, and earlier-served defendants may consent even if their own periods have expired. This resolved a longstanding circuit split in favor of the later-served rule — but note the limitation illustrated in the opening example: an earlier-served defendant that has let its own period lapse cannot itself initiate removal, and courts examine which defendant filed.

The rule of unanimity, § 1446(b)(2)(A) — all defendants who have been properly joined and served must join in or consent to the removal.

  • Consent must be timely and should be filed in writing by each defendant or its counsel; most circuits permit one defendant to represent the others' consent in the notice, but the safer practice is separate written consents.
  • Not required from: defendants not yet served; nominal or formal parties; fraudulently joined defendants; and separate and independent federal claims in the narrow § 1441(c) circumstance.
  • Not required at all in federal officer and CAFA removals.

The forum defendant rule, § 1441(b)(2) — a diversity action may not be removed if any of the parties in interest properly joined and served as defendants is a citizen of the state in which the action is brought.

Snap removal. Because the rule applies only to defendants "properly joined and served," several circuits have permitted a forum defendant to remove before it is served, monitoring the docket and removing the moment the case is filed. The Second, Third, and Fifth Circuits have endorsed the practice on the statute's plain text; district courts elsewhere are divided, and some have rejected it as producing an absurd result. The practice is real, it is used in mass tort and product cases, and its availability depends on the circuit.

The forum defendant rule is procedural, not jurisdictional, in most circuits — which means a violation is waived if not raised within 30 days of removal.

The one-year limitation, § 1446(c)(1) — a case may not be removed on diversity grounds more than one year after commencement of the action, unless the district court finds that the plaintiff has acted in bad faith to prevent removal. Section 1446(c)(3)(B) provides that the court may find bad faith where the plaintiff deliberately failed to disclose the actual amount in controversy. Deliberately joining and then dismissing a non-diverse defendant to run out the year is the paradigm case. The limitation applies only to diversity removals, not to federal question removals.

The notice of removal and the procedure

Section 1446(a) requires a notice of removal signed under Rule 11, containing a short and plain statement of the grounds for removal, together with a copy of all process, pleadings, and orders served on the defendant.

Contents of a complete notice:

  1. The state court, caption, case number, and filing date.
  2. The date each defendant was served, and by what method — establishing timeliness.
  3. The jurisdictional basis, pleaded with facts:
    • For diversity: the citizenship of every party, traced through every tier for unincorporated entities, at both filing and removal; and the amount in controversy with the basis.
    • For federal question: the federal claim and the statute.
  4. That the forum defendant rule does not bar removal, where relevant.
  5. That all served defendants consent, with the consents attached or separately filed.
  6. That the notice is timely, with the calculation.
  7. Attachment of all process, pleadings, and orders served on the defendant.
  8. A statement that the state court will be given written notice and a copy filed with the state court clerk, as § 1446(d) requires.
  9. Compliance with any local rule requiring a state court docket sheet, a corporate disclosure statement under Rule 7.1, or a civil cover sheet. Note that Rule 7.1(a)(2) now requires a party in a diversity case to file a disclosure statement naming every person whose citizenship is attributed to it.

Section 1446(d) — promptly after filing, the removing party must give written notice to all adverse parties and file a copy of the notice with the clerk of the state court, which effects the removal and requires the state court to proceed no further unless and until the case is remanded.

Filing fee, and the case proceeds in federal court. Rule 81(c)(2) governs the time to respond after removal: a defendant that did not answer in state court must answer or present other defenses within the longest of 21 days after receiving the initial pleading, 21 days after service of the summons, or 7 days after the notice of removal is filed. That seven-day trap catches defendants who assume the federal answer period restarts at 21 days.

Rule 81(c)(3) governs jury demands after removal — a party who made an express demand in state court need not renew it, but where state law did not require a demand, the court may direct that one be filed.

Repleading is not required; state court pleadings stand. But a defendant frequently should file a Rule 12 motion promptly, because the federal plausibility standard may differ from the state court's.

Remand

Section 1447(c) provides two distinct paths, and the distinction governs everything.

Procedural defects — anything other than a lack of subject matter jurisdiction — must be raised by a motion to remand filed within 30 days after the filing of the notice of removal, or they are waived. Procedural defects include:

  • Untimely removal.
  • Failure of unanimity.
  • Violation of the forum defendant rule (in most circuits).
  • Violation of the one-year limitation (treated as procedural in most circuits).
  • Defects in the notice's form or attachments.

Lack of subject matter jurisdiction may be raised at any time before final judgment, by any party or by the court sua sponte, and remand is mandatory. A case tried to verdict in federal court without diversity is remanded, and the judgment vacated, which is why the citizenship allegations deserve real attention.

The burden is on the removing party to establish jurisdiction, and doubts are resolved in favor of remand. Removal statutes are strictly construed.

Post-removal events:

  • A reduction in the amount in controversy after removal does not defeat jurisdiction, because jurisdiction is measured at the time of removal. St. Paul Mercury Indemnity Co. v. Red Cab Co., 303 U.S. 283 (1938). A plaintiff's post-removal stipulation limiting damages generally does not require remand, though a pre-removal binding stipulation may prevent removal in the first place.
  • Adding a non-diverse defendant after removal is governed by § 1447(e): the court may deny joinder or permit joinder and remand. Courts weigh the purpose of the amendment, the timeliness, the prejudice, and the plaintiff's diligence.
  • Dismissal of the federal claims leaves supplemental jurisdiction over state claims, which the court may decline to exercise under § 1367(c)(3) — a discretionary remand that is common where the federal claims drop out early.
  • Voluntary dismissal of a non-diverse defendant by the plaintiff can make a previously non-removable case removable, subject to the one-year limit. An involuntary dismissal by the court generally does not, under the voluntary-involuntary rule applied in most circuits.

Appealability. Section 1447(d) provides that an order remanding a case is not reviewable on appeal or otherwise, except for cases removed under § 1442 (federal officer) or § 1443 (civil rights). BP P.L.C. v. Mayor and City Council of Baltimore, 593 U.S. 230 (2021), held that when a remand order is appealable because the case was removed under § 1442 or § 1443, the court of appeals may review the order in full, including the other grounds for removal. CAFA removals have their own discretionary appeal provision under § 1453(c), with a 10-day petition window and a defined decision timeline.

The practical consequence: a remand order on jurisdictional grounds is generally the end of the matter. This asymmetry — removal is reviewable only in narrow circumstances, remand almost never — is why the notice must be right the first time.

Fee awards on remand. Section 1447(c) permits an order requiring payment of just costs and any actual expenses, including attorney's fees, incurred as a result of the removal. Martin v. Franklin Capital Corp., 546 U.S. 132 (2005), holds that fees should be awarded only where the removing party lacked an objectively reasonable basis for seeking removal. A removal that fails on a close question does not ordinarily produce fees; a removal that ignores a facially obvious defect — an untimely filing, an unconsented co-defendant, or a plainly non-diverse party — may.

Fraudulent joinder and misjoinder

Fraudulent joinder permits a removing defendant to have a non-diverse defendant's citizenship disregarded.

The standard is demanding and varies slightly by circuit, but generally requires the removing party to show either:

  • Outright fraud in the plaintiff's pleading of jurisdictional facts; or
  • No possibility that the plaintiff can establish a cause of action against the non-diverse defendant in state court — sometimes phrased as no reasonable basis for predicting that state law might impose liability.

Key features:

  • The burden is heavy and on the removing party, and all disputed facts and ambiguities in state law are resolved in the plaintiff's favor.
  • The standard is more lenient to the plaintiff than Rule 12(b)(6) — a claim that would be dismissed may still defeat fraudulent joinder in several circuits, because the question is whether any possibility of recovery exists.
  • Courts may conduct a limited piercing of the pleadings, considering summary-judgment-type evidence on discrete and undisputed facts — for example, an affidavit establishing that the individual defendant never worked at the location — but may not resolve genuinely contested issues.
  • The motive for joining the defendant is irrelevant; a plaintiff may join a non-diverse defendant precisely to defeat removal, provided the claim is colorable.

Common contexts: the local retailer or distributor in a product case, protected by an innocent seller statute; the individual employee named alongside the employer in a discrimination case where the statute does not permit individual liability; the local sales representative in a fraud case; and the resident agent or adjuster in an insurance bad faith case.

Fraudulent misjoinder — the Tapscott doctrine — is a distinct and more controversial theory: that claims against a diverse defendant have been improperly joined with unrelated claims against a non-diverse defendant, and the misjoined claims should be severed and the remainder removed. It has been adopted in some circuits, rejected or questioned in others, and should not be relied on without checking the forum.

Practical guidance for the removing party: develop the record before removing. An affidavit from the non-diverse defendant establishing the dispositive fact, attached to the notice, is far more effective than an argument. And where the theory is genuinely close, weigh the fee exposure under Martin against the value of the forum.

Practical guidance for the plaintiff: plead a specific, factual claim against the non-diverse defendant, with the same specificity as against the primary defendant. A count that names the local defendant in a collective "Defendants" allegation is the fact pattern that supports fraudulent joinder findings.

CAFA removal

The Class Action Fairness Act, 28 U.S.C. §§ 1332(d), 1453, was enacted to move interstate class actions into federal court, and it relaxes several ordinary removal requirements.

Jurisdiction exists where:

  • The proposed class has at least 100 members;
  • Minimal diversity — any class member is a citizen of a state different from any defendant; and
  • The aggregate amount in controversy exceeds $5 million, exclusive of interest and costs.

Removal is easier under § 1453:

  • No unanimity required — any defendant may remove.
  • The forum defendant rule does not apply.
  • The one-year limitation does not apply.
  • Appellate review of a remand order is available in the court of appeals' discretion, on a petition filed within 10 days.

Aggregation of class members' claims is permitted, which is the central change from ordinary diversity practice.

The mandatory exceptions, on which the plaintiff bears the burden:

  • Local controversy, § 1332(d)(4)(A) — more than two-thirds of the class are citizens of the forum state; at least one defendant from whom significant relief is sought and whose conduct forms a significant basis for the claims is a citizen of the forum state; the principal injuries were incurred in the forum state; and no other class action asserting similar allegations was filed against any defendant in the preceding three years.
  • Home state, § 1332(d)(4)(B) — two-thirds or more of the class and the primary defendants are citizens of the forum state.

The discretionary exception, § 1332(d)(3), where between one-third and two-thirds of the class and the primary defendants are citizens of the forum state, applying six enumerated factors.

Also excluded: certain securities class actions and claims relating to the internal affairs of a corporation, § 1332(d)(9).

Mass actions, § 1332(d)(11) — 100 or more persons proposing to try claims jointly on the ground that they involve common questions — are treated as class actions for CAFA purposes, subject to their own conditions, including that each plaintiff's claim exceed $75,000.

Note also the Securities Litigation Uniform Standards Act, which permits removal of covered class actions asserting state-law securities claims for dismissal, and the Class Action Fairness Act's notice requirement to federal and state officials on a proposed settlement, § 1715.

Strategy: whether to remove

Removal is a right, not an obligation, and the decision deserves analysis rather than reflex.

Reasons to remove:

  • The judge and the docket. Federal judges have smaller caseloads, more law clerk support, and generally engage more with dispositive motions. A defendant with a strong Rule 12 or summary judgment argument frequently prefers federal court for that reason alone.
  • The jury pool. Federal districts draw from a broader geographic area than a county court, which in a case filed in a plaintiff-friendly county can substantially change the composition.
  • Pleading standards. Twombly and Iqbal apply after removal, and several states retain notice pleading. A complaint sufficient in state court may not survive in federal court.
  • Expert admissibility. Rule 702 as amended, and Daubert, apply — and several states apply a more permissive standard.
  • Discovery. The federal proportionality standard, initial disclosures, expert report requirements, and the presumptive limits on depositions and interrogatories.
  • Summary judgment practice, which in some state systems is materially less developed.
  • Class certification under Rule 23 as applied by federal courts, including the Comcast damages-model requirement, which several state courts apply less rigorously.
  • Consistency for a defendant facing parallel cases in many states.
  • Appellate review by a court whose precedent the defendant knows.

Reasons not to remove:

  • The state judge is better for this case — familiarity with the subject, a favorable docket, or a preferable local rule.
  • Speed. Some state courts try cases substantially faster, which matters where delay favors the plaintiff.
  • Cost. Federal practice is generally more expensive.
  • The removal is weak, and a failed removal costs 60 to 120 days, a fee award risk under Martin, and credibility with the state judge who will keep the case.
  • A forum selection or arbitration clause makes the forum question academic.
  • Remand is likely on a discretionary basis — for example, where the federal claims will drop out early.

For the plaintiff, defeating removal begins at drafting:

  • Plead a real claim against a non-diverse defendant, with specific facts, so that fraudulent joinder fails.
  • Do not plead a federal claim you do not need, and do not reference federal law in a way that raises a Grable question.
  • Consider a binding pre-removal stipulation limiting damages below the threshold where the case is genuinely small — noting that this is a real limit on recovery and that post-removal stipulations generally do not work.
  • Avoid pleading a specific amount above the threshold where the state's rules permit.
  • Where removal occurs, move to remand within 30 days on any procedural ground, and preserve jurisdictional arguments for later.

For the defendant, preserving removal:

  • Calendar the 30 days from service on the day of service, for each defendant separately.
  • Obtain consents in writing immediately, and file them.
  • Trace the citizenship chain for every unincorporated party before filing, and conduct jurisdictional discovery in state court if needed — carefully, because a discovery request can itself start an "other paper" clock.
  • Monitor for "other paper" — a settlement demand, a discovery response, or an amended pleading — and calendar 30 days from receipt.
  • Watch the one-year limitation in diversity cases, and document any facts suggesting bad faith concealment.
  • Do not litigate substantively in state court before removing. Filing a demurrer, seeking affirmative relief, or participating in a hearing on the merits can waive removal.

Related and recurring problems

Waiver of removal by conduct. A defendant that takes substantial action in state court demonstrating an intent to litigate on the merits may waive the right — filing a counterclaim in some circuits, moving for summary judgment, or proceeding to trial. Purely defensive acts, an answer, and routine discovery generally do not waive.

Contractual waiver. A forum selection clause requiring litigation in a specified state court can waive removal if it is mandatory and clear. Courts require a clear and unequivocal waiver.

Removal of an arbitration-related matter. Section 9 of the FAA permits removal of a proceeding to confirm an award where the underlying dispute is otherwise within federal jurisdiction; Badgerow v. Walters, 596 U.S. 1 (2022), held that a federal court may not look through to the underlying dispute to establish jurisdiction over a § 9 or § 10 petition — a change that has pushed many award confirmation and vacatur proceedings into state court.

Removal after a bankruptcy filing. Section 1452 permits removal of claims related to a bankruptcy case, on a different timetable set by Bankruptcy Rule 9027, and permits equitable remand on any equitable ground — a broader standard than § 1447 and one that is not reviewable on appeal.

Multiple removals. A second removal is permitted where a new basis arises after the first remand — for example, an amended complaint adding a federal claim, or the dismissal of the non-diverse defendant — but not on the same grounds already rejected.

Removal and the state court's actions. Once § 1446(d) is satisfied, the state court may proceed no further. Orders entered by a state court after removal are void, and any order entered before removal remains in effect until dissolved or modified by the federal court, § 1450.

Service after removal. Process not completed before removal may be completed or new process issued in the federal action, § 1448.

A worked example

Cordova v. Meridian Equipment and Halverson Rental, filed in Texas state court. Plaintiff is a Texas citizen. Meridian is a Delaware corporation with its nerve center in Illinois. Halverson Rental is a Texas LLC.

Day 0 (June 2). Meridian is served. Counsel calendars July 2.

Day 1. Counsel begins the analysis:

  • Citizenship — Halverson is an LLC. Counsel obtains its members from public filings and a records request: two individual members, both Texas citizens. Halverson is therefore a Texas citizen and its presence defeats both complete diversity and the forum defendant rule.
  • Fraudulent joinder — Halverson rented the equipment. The complaint alleges negligent maintenance. Texas law permits such a claim against a lessor. Counsel concludes the theory is not strong: there is at least a possibility of recovery, and the disputed maintenance facts cannot be resolved on a limited piercing.
  • Amount in controversy — the complaint pleads no amount but alleges permanent disability. Counsel obtains the medical special damages, which exceed $300,000.

Day 14. Halverson is served. Its own 30-day period runs to July 16.

The decision. Counsel does not remove, because complete diversity is absent and the fraudulent joinder theory is weak enough that removal would likely produce a remand and a fee application.

Month 8 (February). Plaintiff, having obtained the maintenance records, voluntarily dismisses Halverson with prejudice. Counsel receives the notice of dismissal on February 10.

The analysis now:

  • Complete diversity exists as of the dismissal.
  • The dismissal was voluntary, satisfying the voluntary-involuntary rule.
  • The notice of dismissal is an "other paper" under § 1446(b)(3), starting a new 30-day period ending March 12.
  • The one-year limitation runs from commencement on June 2, expiring the following June 2 — so the removal is within it.
  • The forum defendant rule no longer applies, because the only remaining defendant is not a Texas citizen.

February 21. Meridian files a notice of removal pleading: the service dates, the dismissal and its date, the citizenship of both remaining parties with the corporate nerve center analysis, the amount in controversy supported by the medical specials, the timeliness calculation under § 1446(b)(3), compliance with the one-year limit, and no unanimity issue because it is the sole remaining defendant. It attaches all state court process, pleadings, and orders, files the § 1446(d) notice with the state court, and files a Rule 7.1 disclosure.

March 3. Plaintiff moves to remand, arguing the dismissal was not an "other paper." The motion is denied. The case proceeds in federal court.

What made the difference: not removing when the theory was weak, and recognizing the second window when it opened.

Frequently asked questions

When does the 30 days start? On formal service of the initial pleading, not on informal receipt, Murphy Bros. Each defendant has its own 30 days from its own service.

Do all defendants have to agree? Yes, for ordinary removal — all properly joined and served defendants must join or consent in writing, timely. Not required for federal officer or CAFA removals.

Can a local defendant remove? Not under § 1441(b)(2) if it has been properly joined and served — which is the textual gap the snap removal practice exploits, and which several circuits have endorsed.

What if we discover diversity a year into the case? For diversity removals, § 1446(c)(1) bars removal more than one year after commencement, unless the plaintiff acted in bad faith to prevent it. There is no one-year limit on federal question removals.

Can the plaintiff avoid removal by suing a local defendant? Yes, if the claim against that defendant is colorable. Fraudulent joinder requires showing no possibility of recovery, which is a heavy burden.

Is a remand order appealable? Generally no, § 1447(d), with exceptions for federal officer and civil rights removals and a discretionary appeal in CAFA cases.

Can we be ordered to pay fees for a failed removal? Yes, if you lacked an objectively reasonable basis, Martin v. Franklin Capital. A close call ordinarily does not produce fees.

When is the answer due after removal? Under Rule 81(c)(2), the longest of 21 days after receiving the pleading, 21 days after service of the summons, or 7 days after the notice of removal — a deadline that catches defendants expecting a fresh 21 days.

Conclusion

Removal is one of the few decisions in litigation that is made once, quickly, on a fixed clock, and cannot be revisited. The forum it selects will shape the pleading standard, the discovery, the expert rulings, the jury pool, and the appellate court for the life of the case.

Three mechanical points decide most removals. Calendar the 30 days from formal service, per defendant, on the day of service. Trace the citizenship of every unincorporated party through every tier before you file, because that is where the jurisdictional defects live and because a defect there can undo a judgment years later. And get written consents from every served defendant, because unanimity failures are procedural, waivable, and entirely avoidable.

Everything else — fraudulent joinder, CAFA exceptions, complete preemption — is substantive analysis worth doing carefully. But the removals that fail usually fail on the calendar.
