What Is the Amount in Controversy Requirement?
The amount in controversy is the dollar value a plaintiff must plausibly claim to invoke federal diversity jurisdiction. Under 28 U.S.C. § 1332(a), that claim must exceed $75,000, exclusive of costs and interest, and it is measured as of the date the complaint is filed.
If you’re studying for the California Bar Exam, this rule rarely appears alone. It almost always shows up bolted onto a diversity jurisdiction question, and the examiners love to bury an aggregation trap inside an otherwise easy fact pattern.
The Good-Faith and Legal-Certainty Standard
A plaintiff doesn’t have to prove the amount in controversy with precision at the filing stage. Under St. Paul Mercury Indemnity Co. v. Red Cab Co., a good-faith allegation of more than $75,000 controls unless it appears to a legal certainty that the plaintiff cannot actually recover that much.
That’s a deliberately plaintiff-friendly standard. Courts don’t want to litigate the merits of a damages claim just to decide whether they have jurisdiction to hear the case at all. Two mechanical rules follow from the statute itself:
- Costs and interest are always excluded from the calculation, no matter how the complaint phrases the demand.
- Punitive damages count if the underlying substantive law allows them; attorney’s fees count only if a statute or contract authorizes fee-shifting.
The Aggregation Rules — The Highest-Yield Trap
This is where most students lose points. The aggregation rules are asymmetric depending on how many plaintiffs and defendants are in the case, and examiners exploit that asymmetry constantly.
| Scenario | Aggregation rule |
|---|---|
| One plaintiff v. one defendant | May aggregate all claims, related or unrelated, to reach $75,000 |
| Multiple plaintiffs | May not aggregate — each plaintiff must independently exceed $75,000, unless they share a true joint/undivided interest |
| Multiple defendants | Amount in controversy is tested separately against each defendant; joint-and-several liability does not create a common interest that lets you pool damages |
The “joint and undivided interest” exception is narrow. It covers things like co-owners of a single piece of property or co-beneficiaries of one trust — situations where the plaintiffs’ economic stakes are genuinely fungible, not just factually related.
Supplemental Jurisdiction Can Cure a Shortfall
Exxon Mobil Corp. v. Allapattah Services, Inc. (2005) softened the multiple-plaintiff rule in one important respect: if a named or representative plaintiff independently satisfies both complete diversity and the $75,000 threshold, supplemental jurisdiction under 28 U.S.C. § 1367 can pull in additional plaintiffs whose individual claims fall short.
This is precisely how Rule 23(b)(3) class actions survive in federal diversity court even though most absent class members have claims worth far less than $75,000 — as long as the class representative clears the bar alone.
Equitable Relief and the Viewpoint Split
When a plaintiff seeks an injunction or declaratory judgment instead of money damages, there’s no obvious dollar figure to test against $75,000. Federal circuits split on how to value the claim:
- Plaintiff’s-viewpoint test — value of the right to the plaintiff.
- Defendant’s-viewpoint test — cost to the defendant of complying.
- Either-viewpoint rule — jurisdiction exists if either party’s number clears $75,000.
For exam purposes, pick a viewpoint, apply it consistently, and flag the split. Graders reward the reasoning, not a single “correct” answer.
California’s Different (and Non-Jurisdictional) Threshold
California superior courts use a completely separate dollar line: cases are classified as “limited” civil cases (claims of $25,000 or less) or “unlimited” civil cases (more than $25,000). That classification affects pleading formalities and discovery limits, but — unlike the federal $75,000 rule — it is never jurisdictional.
A California case filed under the wrong classification is fixed by administrative reclassification, not dismissal. Bar examiners often set a California-flagged fact pattern specifically to see whether you’ll conflate this $25,000 procedural line with the federal $75,000 jurisdictional gate. Don’t.
Worked Example
Anne, a California citizen, sues Bob, a Nevada citizen, in federal court on two claims against him: a $40,000 breach of contract claim and a completely unrelated $50,000 conversion claim from a different transaction. Bob moves to dismiss, arguing neither claim alone reaches $75,000.
Analysis: The motion fails. Because this is a single plaintiff against a single defendant, Anne may aggregate unrelated claims freely — $40,000 + $50,000 = $90,000, comfortably over $75,000. Complete diversity is satisfied (California v. Nevada), and the claims need not share a common transaction or occurrence for aggregation purposes; that requirement matters for joinder and supplemental jurisdiction, not for amount-in-controversy math between one plaintiff and one defendant.
Common Mistakes to Avoid
- Aggregating claims across multiple plaintiffs who don’t share a joint interest.
- Adding costs and interest into the jurisdictional calculation.
- Pooling damages across multiple defendants to hit $75,000.
- Treating California’s $25,000 limited/unlimited line as a jurisdictional bar.
- Forgetting the legal-certainty test and dismissing a plausible, good-faith claim too quickly.
FAQ
Does the amount in controversy include attorney’s fees?
Only if a statute or contract authorizes fee-shifting for the prevailing party. Otherwise, attorney’s fees are excluded, along with costs and interest, from the $75,000 calculation.
Can a court dismiss a case for failing to meet the amount in controversy after filing?
Yes, but only if it appears to a legal certainty that the plaintiff cannot recover more than $75,000 — a good-faith allegation at filing is normally enough to survive a motion to dismiss.
Is California’s $25,000 civil case threshold the same as the federal amount in controversy?
No. California’s limited/unlimited classification at $25,000 is a procedural, non-jurisdictional line used by state superior courts, while the federal $75,000 threshold under 28 U.S.C. § 1332 is a jurisdictional requirement for diversity cases.
Key Takeaways
- The amount in controversy must exceed $75,000, exclusive of costs and interest, to support diversity jurisdiction.
- A single plaintiff against a single defendant may aggregate all claims; multiple plaintiffs generally may not.
- Multiple defendants are tested individually — no pooling damages across them.
- Supplemental jurisdiction under Exxon Mobil v. Allapattah can cure a shortfall for additional plaintiffs if the named plaintiff independently qualifies.
- California’s $25,000 limited/unlimited threshold is a different, non-jurisdictional rule — don’t confuse the two on a California Bar Exam essay.
