Federal Answer - General Denial

FEDERAL ANSWER — GENERAL DENIAL

(Universal Template for Use in Any United States District Court)

CRITICAL DRAFTING WARNING — READ BEFORE USING THIS TEMPLATE.

Fed. R. Civ. P. 8(b)(3) permits a true general denial only when the defendant in good faith intends to deny every allegation of the complaint, including the jurisdictional grounds. If the defendant does not intend to deny every allegation, Rule 8(b)(3) instead requires either specific denials of designated allegations or a general denial of all allegations except those specifically admitted. Use Section 3 whenever any allegation should be admitted.

The norm in federal court is paragraph-by-paragraph admissions and denials under Rule 8(b)(1)–(5). Use Section 3 of this template (Specific Responses to Numbered Allegations) as the primary mechanism for responding to the complaint, and use Section 2 (General Denial) only if you can certify in good faith that every allegation is denied.

Waiver and forfeiture risks if you file an inadequate answer:
- Rule 8(b)(6): If a responsive pleading is required, an allegation other than one relating to the amount of damages is admitted if it is not denied. If no responsive pleading is required, the allegation is considered denied or avoided.
- Rule 12(h)(1): Lack of personal jurisdiction, improper venue, insufficient process, and insufficient service of process can be waived if omitted from an earlier Rule 12 motion when Rule 12(g)(2) applies, or if neither raised by motion nor included in the responsive pleading or a Rule 15(a)(1) amendment as of course.
- Rule 8(c): Affirmative defenses must be affirmatively pled in the answer; failure to plead is generally treated as forfeiture, although circuits diverge on whether Twombly/Iqbal plausibility applies to affirmative defenses (compare Harris v. Sec'y, U.S. Dep't of Veterans Affairs, 126 F.3d 339, 343–45 (D.C. Cir. 1997) (early-raised defense preserved despite imperfect pleading) with district-court decisions imposing heightened pleading on defenses).
- Rule 13(a): Any compulsory counterclaim (one arising from the same transaction or occurrence as the plaintiff's claim) not asserted in the answer is forever barred in any later action.
- Rule 12(a)(1)(A): For an ordinary defendant, the answer is due 21 days after service. If service was timely waived under Rule 4(d), the period is 60 days after the waiver request was sent, or 90 days after it was sent to a defendant outside any U.S. judicial district. Check Rule 12(a)(2)–(4), any controlling statute, and court orders for other periods.

1. CAPTION

IN THE UNITED STATES DISTRICT COURT
FOR THE [________________________________] DISTRICT OF [________________________________]
[________________________________] DIVISION

DEFENDANT'S ANSWER AND DEFENSES TO PLAINTIFF'S COMPLAINT

Defendant [DEFENDANT FULL LEGAL NAME] ("Defendant"), by and through undersigned counsel, and pursuant to the Federal Rules of Civil Procedure, hereby files this Answer and Defenses to Plaintiff's Complaint [or Amended Complaint] filed on [__/__/____], and responds as follows:

2. INTRODUCTORY STATEMENT AND GENERAL DENIAL

General Denial Pursuant to Fed. R. Civ. P. 8(b)(3)

1. Defendant denies generally each and every allegation, statement, matter, and thing contained in Plaintiff's Complaint, including all exhibits and documents incorporated therein by reference, and denies that Plaintiff is entitled to any relief of any kind or nature whatsoever from Defendant.

2. To the extent any allegation of the Complaint contains or constitutes a conclusion of law, no responsive pleading is required; however, to the extent a response is deemed required, Defendant denies those allegations.

3. Any allegation in the Complaint not expressly and specifically admitted in this Answer is denied.

Important — Good Faith Requirement: Fed. R. Civ. P. 8(b)(3) permits a general denial only when the party "intends in good faith to deny all the allegations of a pleading." Where any facts are clearly true (e.g., identity of the parties, existence of a contract, the court's jurisdiction), practitioners should use paragraph-by-paragraph responses in Section 3 below rather than a blanket general denial. Many judicial districts and individual judges disfavor general denials. Always confirm the practice in your specific court before relying solely on a general denial.

3. SPECIFIC RESPONSES TO NUMBERED ALLEGATIONS

Instruction: Use this section as an alternative to, or in addition to, the general denial in Section 2. Replicate the format below for each numbered paragraph of the Complaint. Under Fed. R. Civ. P. 8(b)(5), a statement that a party "lacks knowledge or information sufficient to form a belief about the truth of an allegation" operates as a denial. Under Fed. R. Civ. P. 8(b)(4), a party that intends to deny only part of an allegation must admit the true part and deny the rest.

Paragraph 1. Defendant ☐ admits / ☐ denies / ☐ admits in part and denies in part / ☐ lacks knowledge or information sufficient to form a belief about the truth of the allegations contained in Paragraph 1 of the Complaint, and therefore denies the same.

Paragraph 2. Defendant ☐ admits / ☐ denies / ☐ admits in part and denies in part / ☐ lacks knowledge or information sufficient to form a belief about the truth of the allegations contained in Paragraph 2 of the Complaint, and therefore denies the same.

Paragraph 3. Defendant ☐ admits / ☐ denies / ☐ admits in part and denies in part / ☐ lacks knowledge or information sufficient to form a belief about the truth of the allegations contained in Paragraph 3 of the Complaint, and therefore denies the same.

Paragraph 4. Defendant ☐ admits / ☐ denies / ☐ admits in part and denies in part / ☐ lacks knowledge or information sufficient to form a belief about the truth of the allegations contained in Paragraph 4 of the Complaint, and therefore denies the same.

Paragraph 5. Defendant ☐ admits / ☐ denies / ☐ admits in part and denies in part / ☐ lacks knowledge or information sufficient to form a belief about the truth of the allegations contained in Paragraph 5 of the Complaint, and therefore denies the same.

Paragraph [____]. Defendant ☐ admits / ☐ denies / ☐ admits in part and denies in part / ☐ lacks knowledge or information sufficient to form a belief about the truth of the allegations contained in Paragraph [____] of the Complaint, and therefore denies the same.

Reminder: Under Fed. R. Civ. P. 8(b)(6), an allegation — other than one relating to the amount of damages — is admitted if a responsive pleading is required and the allegation is not denied. Failing to respond to an allegation constitutes an admission.

4. RULE 12(b) DEFENSES

Without waiving any defense, including the general denial, Defendant asserts the following defenses pursuant to Fed. R. Civ. P. 12(b). Select all that apply:

☐ 12(b)(1) — Lack of Subject-Matter Jurisdiction. This Court lacks subject-matter jurisdiction over all or part of Plaintiff's claims because: [________________________________]. Note: This defense is never waived and may be raised at any time, including on appeal. Fed. R. Civ. P. 12(h)(3).

☐ 12(b)(2) — Lack of Personal Jurisdiction. This Court lacks personal jurisdiction over Defendant because Defendant lacks the minimum contacts with [State] necessary to satisfy due process under the Fourteenth Amendment. Specifically: [________________________________].

☐ 12(b)(3) — Improper Venue. Venue is improper in this judicial district under 28 U.S.C. § 1391 because: [________________________________].

☐ 12(b)(4) — Insufficient Process. The summons or other process served upon Defendant was deficient because: [________________________________].

☐ 12(b)(5) — Insufficient Service of Process. Service of process upon Defendant did not comply with Fed. R. Civ. P. 4 because: [________________________________].

☐ 12(b)(6) — Failure to State a Claim Upon Which Relief Can Be Granted. Plaintiff's Complaint, taken as a whole or as to specific counts, fails to state a claim that is plausible on its face. The Complaint does not contain sufficient factual matter, accepted as true, to state a claim to relief that is plausible on its face. See Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009); Bell Atlantic Corp. v. Twombly, 550 U.S. 544, 570 (2007).

☐ 12(b)(7) — Failure to Join a Party Under Rule 19. Plaintiff has failed to join a required party under Fed. R. Civ. P. 19, specifically: [________________________________], without whom this Court cannot accord complete relief among existing parties.

WAIVER WARNING — Fed. R. Civ. P. 12(h)(1) [READ CAREFULLY]:

Check each of these defenses before filing a Rule 12 motion or Answer. Rule 12(h)(1) waives an available defense omitted from an earlier Rule 12 motion when Rule 12(g)(2) applies. If no such motion was made, raise it by motion, in the responsive pleading, or in an amendment allowed as a matter of course under Rule 15(a)(1):

• Rule 12(b)(2) — Lack of personal jurisdiction
• Rule 12(b)(3) — Improper venue
• Rule 12(b)(4) — Insufficient process
• Rule 12(b)(5) — Insufficient service of process

Per Rule 12(g)(2), a party that files a Rule 12 motion omitting an available 12(b)(2)–(5) defense generally waives that defense even if it later asserts it in the Answer. Consolidate all available 12(b)(2)–(5) defenses in the first Rule 12 motion.

Preserved (less urgent but still must be pled):
- 12(b)(6) Failure to state a claim and 12(b)(7) failure to join a required party — preserved until trial; may be raised in any pleading allowed by Rule 7(a), by Rule 12(c) motion, or at trial.

Never waived:
- 12(b)(1) Subject-matter jurisdiction — may be raised at any stage (including sua sponte by the court or for the first time on appeal). Fed. R. Civ. P. 12(h)(3).

5. AFFIRMATIVE DEFENSES UNDER RULE 8(c)

Subject to and without waiving Defendant's general denial or any other defense, and pursuant to Fed. R. Civ. P. 8(c)(1), Defendant pleads the following affirmative defenses. These defenses are pled in the alternative under Fed. R. Civ. P. 8(d)(2)–(3), and Defendant does not concede the burden of proof on any issue where such burden is not properly Defendant's.

Rule 8(c) Forfeiture Warning: Rule 8(c)(1) requires a responding party to "affirmatively state any avoidance or affirmative defense." Failure to plead an affirmative defense in the answer is generally treated as forfeiture, although courts retain discretion to permit late assertion where the plaintiff is not unfairly prejudiced. See Harris v. Sec'y, U.S. Dep't of Veterans Affairs, 126 F.3d 339, 343–45 (D.C. Cir. 1997) (affirmative defense raised in pretrial filings, before any prejudice, was not forfeited despite omission from answer). Do not rely on the Harris line of cases as a safety net — many circuits enforce strict forfeiture, and amendment is governed by Rule 15(a) and pretrial-order standards.

Twombly/Iqbal and Affirmative Defenses — Circuit Split: The Supreme Court has not resolved whether the Twombly/Iqbal plausibility standard applies to affirmative defenses. District courts are split: some require factual allegations sufficient to make each defense plausible, while others (and most circuit courts that have addressed the issue in dicta) apply only the older "fair notice" standard of Conley v. Gibson. To minimize risk in any forum, plead the factual basis for each affirmative defense rather than a bare label.

Rule 12(f) Motions to Strike: Plaintiffs increasingly move under Rule 12(f) to strike "boilerplate" affirmative defenses. Tailor each defense to the case facts; remove inapplicable defenses before filing.

Affirmative Defenses Checklist

Select all applicable defenses and provide factual basis as required. The 18 enumerated Rule 8(c)(1) defenses are listed first, followed by additional commonly pled defenses.

☐ FIRST AFFIRMATIVE DEFENSE — Statute of Limitations. Plaintiff's claims are barred, in whole or in part, by the applicable statute of limitations. [Identify the statute and limitations period: ________________________________].

☐ SECOND AFFIRMATIVE DEFENSE — Statute of Frauds. Plaintiff's claims are barred because the alleged agreement falls within the statute of frauds and was not memorialized in a writing signed by the party to be charged. [________________________________].

☐ THIRD AFFIRMATIVE DEFENSE — Failure to State a Claim. The Complaint fails to state a claim upon which relief can be granted. See Iqbal, 556 U.S. at 678; Twombly, 550 U.S. at 570.

☐ FOURTH AFFIRMATIVE DEFENSE — Accord and Satisfaction. Plaintiff's claims are barred by a prior accord and satisfaction between the parties. [________________________________].

☐ EIGHTH AFFIRMATIVE DEFENSE — Duress. Any agreement, consent, or action on which Plaintiff relies was obtained under duress and is voidable. [________________________________].

☐ NINTH AFFIRMATIVE DEFENSE — Estoppel. Plaintiff is estopped from asserting the claims alleged by reason of Plaintiff's own conduct, representations, or omissions. [Specify type: ☐ equitable / ☐ judicial / ☐ collateral / ☐ promissory]. [________________________________].

☐ TENTH AFFIRMATIVE DEFENSE — Failure of Consideration. The consideration for the agreement or obligation on which Plaintiff's claims rest has wholly or partially failed. [________________________________].

☐ ELEVENTH AFFIRMATIVE DEFENSE — Fraud. Plaintiff's claims are barred or diminished by Plaintiff's own fraud, material misrepresentation, or concealment of material facts. [________________________________].

☐ TWELFTH AFFIRMATIVE DEFENSE — Illegality. The contract or transaction underlying Plaintiff's claims is void or unenforceable as illegal or contrary to public policy. [________________________________].

☐ THIRTEENTH AFFIRMATIVE DEFENSE — Laches. Plaintiff's claims are barred by the equitable doctrine of laches because Plaintiff unreasonably delayed in bringing this action, to the prejudice of Defendant. [________________________________].

☐ FOURTEENTH AFFIRMATIVE DEFENSE — License. Defendant's alleged conduct was authorized by a license, permission, or consent granted by Plaintiff or by law. [________________________________].

☐ FIFTEENTH AFFIRMATIVE DEFENSE — Payment. The obligation on which Plaintiff's claims rest has been satisfied in whole or in part by payment. [________________________________].

☐ SIXTEENTH AFFIRMATIVE DEFENSE — Release. Plaintiff executed a valid and enforceable release discharging Defendant from the claims alleged. [________________________________].

☐ SEVENTEENTH AFFIRMATIVE DEFENSE — Res Judicata (Claim Preclusion). Plaintiff's claims are barred by res judicata because they arise from the same cause of action that was, or could have been, adjudicated in a prior action between the same parties or their privies. [________________________________].

☐ EIGHTEENTH AFFIRMATIVE DEFENSE — Collateral Estoppel (Issue Preclusion). Plaintiff is collaterally estopped from relitigating issues of fact or law that were actually and necessarily determined in a prior proceeding. [________________________________].

☐ NINETEENTH AFFIRMATIVE DEFENSE — Waiver. Plaintiff waived the rights underlying its claims by its conduct, express agreement, or failure to act in a timely manner. [________________________________].

☐ TWENTIETH AFFIRMATIVE DEFENSE — Unclean Hands. Plaintiff's claims are barred by the doctrine of unclean hands because Plaintiff engaged in inequitable, unconscionable, or bad-faith conduct relating to the matters at issue. [________________________________].

☐ TWENTY-FIRST AFFIRMATIVE DEFENSE — Failure to Mitigate Damages. Plaintiff failed to exercise reasonable diligence to mitigate its alleged damages, and any recovery must be reduced by the amount that could have been avoided. [________________________________].

☐ TWENTY-SECOND AFFIRMATIVE DEFENSE — Set-Off and Recoupment. Defendant is entitled to set off against any recovery by Plaintiff the amounts owed by Plaintiff to Defendant. [________________________________].

☐ TWENTY-THIRD AFFIRMATIVE DEFENSE — Standing. Plaintiff lacks Article III standing because Plaintiff has not demonstrated an injury in fact that is concrete, particularized, and actual or imminent; fairly traceable to the challenged conduct; and redressable by a favorable judicial decision. See Lujan v. Defenders of Wildlife, 504 U.S. 555 (1992); TransUnion LLC v. Ramirez, 594 U.S. 413 (2021).

☐ TWENTY-FOURTH AFFIRMATIVE DEFENSE — Ripeness / Mootness. Plaintiff's claims are not ripe for adjudication because they depend upon future contingent events, or the claims have become moot. [________________________________].

☐ TWENTY-FIFTH AFFIRMATIVE DEFENSE — Privilege and Immunity. Defendant's conduct is protected by applicable privilege or immunity, including: ☐ qualified immunity / ☐ absolute immunity / ☐ statutory immunity / ☐ litigation privilege / ☐ other: [________________________________].

☐ TWENTY-EIGHTH AFFIRMATIVE DEFENSE — Injury by Fellow Servant. Plaintiff's injuries were caused by a fellow servant and not by Defendant. [________________________________].

☐ TWENTY-NINTH AFFIRMATIVE DEFENSE — Reservation of Additional Defenses. Defendant reserves the right to assert additional affirmative defenses as they become known through discovery, investigation, or further analysis, pursuant to Fed. R. Civ. P. 15(a).

6. COUNTERCLAIM (PLACEHOLDER)

COMPULSORY COUNTERCLAIM WARNING — Fed. R. Civ. P. 13(a) [LOSS-OF-CLAIM RISK]:

A counterclaim is compulsory under Rule 13(a)(1) if, at the time of service of the answer, the pleader has the claim against an opposing party and the claim (A) arises out of the transaction or occurrence that is the subject matter of the opposing party's claim, and (B) does not require adding another party over whom the court cannot acquire jurisdiction.

A compulsory counterclaim that is not asserted in this Answer is FOREVER BARRED. It cannot be brought in a later federal action and is generally precluded in any state-court action under the doctrine of res judicata/issue preclusion. The bar applies even if Defendant did not realize the claim existed, unless Defendant qualifies for a Rule 13(a)(2) exception (claim already pending in another action, or in rem/quasi-in-rem cases).

Most federal courts apply a "logical relationship" test to determine whether a claim arises out of the same transaction or occurrence. Before filing this Answer, conduct a thorough audit of every potential claim Defendant may have against Plaintiff (or any party that could be joined under Rule 13(h)), including contract, tort, statutory, and equitable claims, and assert each that is colorably compulsory.

Permissive counterclaims under Rule 13(b) — claims not arising out of the same transaction or occurrence — are not forfeited by omission and may be brought in a separate action, but consolidation here is often more efficient and may be jurisdictionally easier (supplemental jurisdiction under 28 U.S.C. § 1367).

☐ Defendant asserts no counterclaims at this time but reserves the right to amend this Answer to assert counterclaims under Fed. R. Civ. P. 13 and 15.

☐ Defendant asserts the following counterclaim(s) against Plaintiff:

COUNTERCLAIM

COUNT I — [________________________________]

1. Defendant realleges and incorporates by reference each and every paragraph of this Answer as if fully set forth herein.

2. [State facts supporting the counterclaim: ________________________________]

3. [State the legal basis for the counterclaim: ________________________________]

4. [State the damages or relief sought: ________________________________]

5. As a direct and proximate result of Plaintiff's conduct described herein, Defendant has suffered damages in the amount of $[________________________________], or in an amount to be proven at trial, together with interest, costs, and attorneys' fees as permitted by law.

PRAYER FOR RELIEF ON COUNTERCLAIM

WHEREFORE, Defendant respectfully requests that this Court enter judgment against Plaintiff on the Counterclaim as follows:

a. Awarding Defendant compensatory damages in an amount to be determined at trial;

b. Awarding Defendant pre-judgment and post-judgment interest;

c. Awarding Defendant its reasonable attorneys' fees and costs; and

d. Granting such other and further relief as the Court deems just and proper.

7. PRAYER FOR RELIEF

WHEREFORE, Defendant [DEFENDANT FULL LEGAL NAME] respectfully requests that this Court enter judgment as follows:

a. Dismissing Plaintiff's Complaint in its entirety, with prejudice, and with each party to bear its own costs (or, alternatively, with costs assessed against Plaintiff);

b. Entering judgment in favor of Defendant on all claims asserted in the Complaint;

c. Awarding Defendant its reasonable attorneys' fees and costs of suit to the extent permitted by applicable law, contract, or statute;

d. Awarding Defendant pre-judgment and post-judgment interest at the maximum lawful rate;

e. If applicable, entering judgment in Defendant's favor on all counterclaims; and

f. Granting such other and further relief as this Court deems just, equitable, and proper.

8. RESERVATION OF RIGHTS

Defendant expressly reserves all rights, remedies, claims, and defenses available under applicable federal and state law, in equity, by contract, or otherwise, whether or not specifically set forth in this Answer. No allegation, admission, denial, or defense stated herein shall be construed as a waiver of any right or defense not expressly waived. Defendant further reserves the right to amend or supplement this Answer, including to assert additional defenses, counterclaims, crossclaims, or third-party claims, pursuant to Fed. R. Civ. P. 13, 14, and 15.

9. JURY DEMAND

Pursuant to Fed. R. Civ. P. 38(b), Defendant hereby demands a trial by jury on all issues so triable in this action, including all claims asserted in the Complaint and all counterclaims asserted herein.

Timing Requirement: Under Fed. R. Civ. P. 38(b), a party may demand a jury trial by serving the other parties with a written demand no later than 14 days after the last pleading directed to the issue is served. Under Fed. R. Civ. P. 38(d), a party waives a jury trial unless its demand is properly served and filed. Check local rules for any additional requirements (e.g., some courts require the designation "JURY TRIAL DEMANDED" in the case caption).

12. PRACTICE NOTES — TIMING, DEADLINES, AND LOCAL RULES

Response Deadlines Under Fed. R. Civ. P. 12(a)

Critical Practice Reminders

• General Denial Limitation: A general denial under Fed. R. Civ. P. 8(b)(3) is proper only when the defendant can, in good faith, deny every allegation. Otherwise, specifically deny designated allegations or generally deny all allegations except those specifically admitted.

• Effect of Not Denying: Under Fed. R. Civ. P. 8(b)(6), any allegation (except damages) not denied in a required responsive pleading is deemed admitted. This is one of the most significant risks in drafting an answer — every allegation must be addressed.

• Compulsory Counterclaim Forfeiture: Under Fed. R. Civ. P. 13(a), a counterclaim that arises from the same transaction or occurrence as the plaintiff's claim is compulsory and must be asserted in the answer. Failure to do so generally bars the claim in a later action.

• Amendment as of Right: Under Fed. R. Civ. P. 15(a)(1), a party may amend its pleading once as a matter of course within (A) 21 days after serving it, or (B) if the pleading is one to which a responsive pleading is required, 21 days after service of a responsive pleading or 21 days after service of a Rule 12(b), (e), or (f) motion, whichever is earlier.

• Rule 11 Certification: By presenting a pleading to the court, an attorney certifies under Fed. R. Civ. P. 11(b) that the factual contentions have evidentiary support, the denials are warranted on the evidence or reasonably based on belief or a lack of information, and the legal contentions are warranted by existing law or a nonfrivolous argument for modification.

• Local Rules Are Mandatory: Each of the 94 federal judicial districts has local rules that may impose additional requirements on answers, including page limits, font and margin specifications, required certifications, meet-and-confer requirements, and courtesy copy procedures. Failure to comply with local rules may result in the pleading being stricken. Always review the local rules and any standing orders of the assigned judge before filing.

• CM/ECF Requirements: Federal courts generally require electronic filing via the CM/ECF system. Verify the court's specific requirements for document format (PDF), file size limits, redaction of personal identifiers under Fed. R. Civ. P. 5.2, and proper event selection during filing.

• Service Incentive for Waiver: Under Fed. R. Civ. P. 4(d)(2), a defendant who waives formal service receives 60 days (or 90 days if abroad) to answer instead of 21 days — an incentive that benefits both parties by reducing costs.
