name: counterclaim-crossclaim language: en description: Drafts court-ready counterclaims and crossclaims for commercial litigation. Analyzes case documents, classifies compulsory vs. permissive counterclaims, ensures procedural compliance with federal/state rules, and structures causes of action with proper element pleading. Use when a defendant must assert affirmative claims against the plaintiff or crossclaims against co-defendants during pleadings.

Counterclaim & Crossclaim

Drafts counterclaim and/or crossclaim pleadings asserting a defendant's affirmative claims against the plaintiff or co-defendants, satisfying procedural and substantive pleading requirements.

Prerequisites

1. Original complaint — full text with caption, case number, court, filing date
2. Case documents — contracts, correspondence, invoices, emails, evidence
3. Party information — names, roles, addresses, relationships (including co-defendants for crossclaims)
4. Jurisdictional details — court, rules of civil procedure, local rules, formatting requirements
5. Legal authority — statutes, regulations, case law for each cause of action

Quick Start

1. Extract case identifiers and build a chronological fact timeline from provided documents
2. Classify each potential claim as compulsory or permissive (FRCP 13(a)/(b) or state equivalent)
3. Run the procedural compliance checklist below
4. Assemble the pleading using the document structure
5. Verify all element requirements per the cause of action table

Workflow

Step 1: Document Review & Fact Extraction

Task	Details
Extract identifiers	Court, caption, case number, party designations
Build timeline	Formation → performance → breach → damages → plaintiff's wrongful conduct
Identify counterclaim targets	Same transaction/occurrence (compulsory) or related matters (permissive)
Identify crossclaim targets	Co-defendants liable under contribution, indemnification, or independent theories
Catalog damages	Specific amounts, dates, causation chain, continuing damages

Step 2: Procedural Compliance

• Compulsory vs. permissive status (FRCP 13(a)/(b) or state equivalent)
• Crossclaim from same transaction/occurrence (FRCP 13(g) or state equivalent)
• Statute of limitations for each cause of action
• Jurisdictional basis: supplemental for counterclaims; independent or supplemental for crossclaims
• Local rules: caption format, margins, font, spacing, page limits, e-filing
• Verification requirement (party vs. attorney)
• Heightened pleading (FRCP 9(b) for fraud: who, what, when, where, how)

Step 3: Document Assembly

Structure the pleading with these sections in order:

Caption — Mirror original complaint; add Counterclaimant/Counter-Defendant/Cross-Claimant/Cross-Defendant designations; title "COUNTERCLAIM AND CROSSCLAIM" (or separate documents per local rules)

Introductory Statement — Filing party, capacity, authorizing rule (FRCP 13/state equivalent), compulsory/permissive nature; for crossclaims: co-defendant targets and legal basis

Jurisdictional Allegations — Subject matter jurisdiction, supplemental jurisdiction (28 U.S.C. § 1367) [VERIFY], amount in controversy, venue

Parties — Full identification with transaction roles; crossclaim defendants: describe liability-creating relationship

Factual Allegations (numbered paragraphs) — Incorporate admissions from complaint by reference; deny/qualify inaccurate allegations; present new facts chronologically; allege damages with specificity (nature, timing, causation, amount)

Causes of Action (separately numbered counts) — Format: "COUNT [N]: [Legal Theory] ([Counterclaim/Crossclaim] Against [Party])". Each count: incorporate factual paragraphs by reference, satisfy each element, cite controlling authority, include theory-specific allegations (fault percentage for contribution, indemnification clause for contractual indemnity)

Prayer for Relief — Compensatory damages, punitive damages (if authorized), injunctive/declaratory relief, attorney's fees (cite basis), pre/post-judgment interest, catch-all clause; separate subsections for counterclaim vs. crossclaim relief

Verification (if required) — Party declaration under penalty of perjury

Signature Block — Attorney name, bar number, firm, contact; "Attorney for Defendant/Counterclaimant/Cross-Claimant [Name]"

Certificate of Service — All parties/counsel, addresses, method, date

Cause of Action Elements

Claim	Required Elements
Breach of Contract	Formation → terms → performance → breach → causation → damages
Fraud	False statement → materiality → scienter → reliance → causation → damages (plead with particularity)
Contribution	Common liability → proportionate fault → right to apportion
Contractual Indemnity	Indemnification clause → triggering event → covered claims → notice
Common Law Indemnity	Special relationship → passive vs. active fault → right to shift liability
Unjust Enrichment	Benefit conferred → knowledge → inequity of retention

Pitfalls & Checks

• Compulsory counterclaim waiver: Failure to assert a compulsory counterclaim typically results in waiver — flag all potentially compulsory claims
• Alternative pleading: Permitted under FRCP 8(d)(2); label "in the alternative" without conceding primary theory
• Relation back: Counterclaims generally relate back to the original filing date for limitations, but verify jurisdiction-specific rules
• Consistency: Party names, dates, amounts, and contract references must match source documents exactly
• Cross-references: Verify all internal paragraph and exhibit references; ensure exhibit labels match text
• All citations must be verified — mark uncertain citations with [VERIFY]
• Do not fabricate facts — plead only from provided case documents
