Definition
An indemnity contract is an agreement in which one party — the indemnitor — undertakes an obligation to protect the other party — the indemnitee — from specified losses, liabilities, damages, or claims. The protection can run in two directions: backward (reimbursing the indemnitee for losses already suffered) or forward (preventing the indemnitee from ever having to bear a loss in the first place).
Indemnity contracts arise in a wide range of contexts: construction subcontracting, commercial leases, insurance policies, technology licensing, professional services agreements, and government contracts, among others. The scope of the indemnitor's obligation depends entirely on the language of the agreement. Courts read indemnity provisions carefully and typically require clear, express language before extending the obligation to cover the indemnitee's own negligence.
The term encompasses two distinct obligations that are often combined in a single clause:
(1) Indemnify: to compensate the indemnitee for losses, damages, or costs already incurred.
(2) Hold harmless (save harmless): to shield the indemnitee from liability arising in the first instance — preventing the loss from attaching rather than compensating after it does.
Whether "indemnify" and "hold harmless" are treated as synonymous or as carrying independent legal weight varies by jurisdiction and by how a court reads the specific contract language.
Common Confusion
Indemnity contract is frequently conflated with two neighboring concepts:
Guarantee: A guarantee is a promise to answer for the debt or obligation of a third party if that party fails to perform. An indemnity contract shifts or absorbs a loss between two contracting parties; a guarantee is a secondary obligation triggered by a primary obligor's default. The practical distinction matters: a guarantor's duty typically requires the creditor to exhaust remedies against the primary obligor first, while an indemnitor's duty is generally primary and direct.
Insurance policy: All insurance policies are a form of indemnity contract, but not all indemnity contracts are insurance policies. The principle of indemnity in insurance law (no profit from a loss) is a narrower doctrine that operates within the broader category. Researchers conflating the two may miss governing law — insurance policies are subject to regulatory regimes, bad faith doctrines, and interpretive rules that do not apply to commercial indemnity clauses generally.
Core Elements
An enforceable indemnity contract requires:
— A valid underlying contract: the indemnity clause must meet ordinary contract formation requirements (offer, acceptance, consideration).
— Identification of the parties: the indemnitor and indemnitee must be identifiable, either by name or by their roles in the transaction.
— Defined scope of coverage: the clause must specify (or allow courts to determine) what losses, claims, damages, or liabilities are covered.
— Triggering event or condition: coverage typically activates upon a specific event — a third-party claim, a defined loss, a breach, or a liability judgment.
— Express language for negligence coverage: most jurisdictions require unmistakably clear language before an indemnitor is held to cover losses caused by the indemnitee's own negligence.
Why It Matters in Research
Indemnity contract is a term with a stable core and wildly variable edges. Historical sources define it accurately in outline, but the doctrinal action has shifted almost entirely into statutory and case law governing specific clauses in specific industries. Several research traps:
Anti-indemnity statutes: Many states have enacted statutes — particularly in the construction and energy sectors — that void indemnity clauses requiring a subcontractor to indemnify a general contractor for the general contractor's own negligence. If you are researching construction or energy contracts in a historical corpus, a clause that was fully enforceable when drafted may be unenforceable today, or vice versa. The historical sources will not flag this.
Scope disputes dominate the case law: The definition of an indemnity contract is rarely litigated. What courts fight over is whether the specific clause covers the specific loss — particularly losses caused by the indemnitee's negligence, intentional acts, or statutory violations. Research should move quickly from the definitional sources to the interpretive case law.
Indemnity versus contribution: In tort contexts, indemnity (full shifting of liability) is distinct from contribution (proportional sharing). The encyclopedia entry on vicarious and joint tort liability addresses this distinction directly and is the better research starting point for that context.
Marine insurance: The P&I (Protection and Indemnity) context in admiralty law uses the term with specific technical meaning shaped by club rules and maritime convention. Researchers crossing from commercial contract indemnity into admiralty should use the marine insurance encyclopedia entry as a bridge.
The "save harmless" formulation appears throughout older contracts and historical sources and is functionally identical to "hold harmless" in most jurisdictions. Researchers encountering the older phrasing should not treat it as a distinct legal category.
Historical Dictionary Support
Black's Law Dictionary defines an indemnity contract as an agreement in which the indemnitor either promises to indemnify and save harmless the indemnitee from loss or damage, or binds himself to perform some particular act, or to protect the indemnitee against third-party liability or claims. The definition draws on the American and English Encyclopaedia of Law.
This definition is serviceable and accurate as far as it goes. Its value is structural — it names the parties correctly, distinguishes the two forms of obligation (reimbursement vs. protection against third-party claims), and signals the contract's dual-function character. What it does not address is interpretive doctrine: the rules courts apply to determine scope, the treatment of negligence, and the anti-indemnity statutory landscape. Researchers using historical dictionary definitions as a proxy for the full legal framework will find themselves underequipped.
The definition's reference to a promise to "do some particular act or thing" reflects an older, broader use of the term that encompassed performance bonds and surety-adjacent instruments. Modern usage has narrowed the term primarily to loss-shifting agreements, and researchers should be alert to the broader historical usage when reading nineteenth- and early twentieth-century sources.
Jurisdictional Note
Anti-indemnity statutes vary significantly by state and by industry. Texas, California, Louisiana, and many other states have specific statutes governing construction indemnity that affect enforceability of broad form indemnity clauses. In the insurance context, indemnity principles are shaped by state insurance regulatory law, which is not uniform. Federal contracts are governed by separate statutory and regulatory frameworks, including the Federal Acquisition Regulation.
