Third-Party Complaint (Impleader)
Produces an FRCP 14 / state-equivalent third-party complaint asserting derivative liability against an impleaded party.
Prerequisites
- Original complaint — full copy for Exhibit A and incorporation by reference
- Derivative-liability basis — indemnification contracts, insurance policies, warranties, or common-law indemnity/contribution facts
- Third-party defendant identity — legal name, registered agent, service address
- Jurisdictional facts — party citizenship (diversity), personal-jurisdiction contacts, venue basis
- Timing status — within 14 days of original answer (as of right) or leave required
Workflow
1. Caption & Introduction
- Full court name, division, original case number
- Party designations: Plaintiff; Defendant and Third-Party Plaintiff; Third-Party Defendant
- Title: "THIRD-PARTY COMPLAINT"
- Opening paragraph citing FRCP 14(a) / state rule and purpose of liability shifting
2. Procedural Posture
- Summarize original complaint: claims, theories, relief sought
- State: "The Complaint is attached as Exhibit A and incorporated by reference"
- Note answer date and timeliness of third-party filing
3. Jurisdiction & Venue
| Type |
Basis |
| Subject matter |
Federal question, diversity (complete + amount), or supplemental under § 1367 |
| Personal jurisdiction |
Contacts, consent, or long-arm statute |
| Venue |
§ 1391 or applicable state rule |
4. Factual Allegations
Present chronologically. Must establish:
- Relationship between Defendant/TPP and Third-Party Defendant
- Specific agreements creating indemnification/defense/warranty obligations — quote key language verbatim
- Third-Party Defendant's acts or omissions contributing to Plaintiff's alleged harm
- Notice to Third-Party Defendant (dates, method, demands, response)
- Causal chain: TPD conduct → Defendant's exposure → Plaintiff's claims
5. Counts
Structure each as a separate numbered count from applicable theories:
| Theory |
Key Elements |
| Contractual Indemnification |
Quote provision; claims fall within scope; conditions precedent met |
| Common-Law Indemnification |
Defendant's liability purely passive/vicarious; TPD is actual wrongdoer |
| Contribution |
Both at fault; apportion per comparative-fault principles |
| Breach of Contract/Warranty |
Obligation, breach, causation to Defendant's exposure |
| Subrogation |
Defendant already paid; TPD bears ultimate responsibility |
Per count: incorporate factual paragraphs by reference, state elements, identify governing law, conclude with entitlement to judgment.
6. Prayer for Relief
Request: (a) judgment for all sums adjudged against Defendant including settlements; (b) full indemnification or contribution; (c) defense costs and attorney's fees (cite contractual or statutory basis); (d) declaratory relief on duty to defend/indemnify; (e) pre- and post-judgment interest; (f) costs of third-party action; (g) further just relief.
7. Signature Block
Standard attorney signature with Rule 11 / state-equivalent certification.
Critical Checks
- Timing: Within 14 days of serving original answer → as of right (FRCP 14(a)(1)). After → motion for leave required.
- Derivative liability only: FRCP 14 requires claims derivative of the original action. Independent claims need separate counterclaim/crossclaim or independent jurisdiction.
- Service: Must serve TPD with the third-party complaint AND original complaint plus all prior pleadings.
- Contract language: Quote indemnification provisions verbatim — never paraphrase trigger language or scope limitations.
- Supplemental jurisdiction: § 1367 typically covers third-party claims, but confirm no statutory exception applies.
- State variations: Check local timing rules, leave requirements, and contribution statutes (UCFA vs. joint-and-several jurisdictions).
- Party consistency: "Defendant and Third-Party Plaintiff" on first reference, then "Defendant/TPP" throughout.
- Rule 11: Every factual allegation must have evidentiary support or be likely to after reasonable investigation.
