Indemnify in Contracts, what It Means and How It Shifts Risk

To indemnify someone is to promise to make good their loss. If your contract says you indemnify the other party, you are agreeing to compensate them for defined losses, costs or claims if and when they arise, even where the law would not otherwise make you pay. An indemnity is one of the most powerful risk-shifting tools in an Australian commercial contract, and also one of the most misunderstood.

This guide explains what an indemnity actually does, and what it can cost you:

• The promise: what "indemnify" means and how an indemnity differs from a damages claim or a guarantee
• The parts of a clause: scope, triggers, exclusions, caps and claim procedures
• Interpretation: how Australian courts read indemnity clauses, including the rule on your own negligence
• Legal limits: where the Australian Consumer Law (ACL) stops indemnities from operating
• A worked example: an indemnity in action, with the fixes a lawyer would negotiate

What an Indemnity Is: A Promise to Make Good a Loss

An indemnity is a contractual promise by one party (the indemnifier) to compensate the other party (the indemnified party) for specified losses, liabilities, costs or claims. Think of it as shifting a risk from one side of the contract to the other. If you agree to indemnify a client for third-party claims that your software infringes copyright, you take on the cost of those claims even though your client's own conduct may have had nothing to do with them.

The key difference from an ordinary damages claim is that an indemnity is usually a primary promise to pay. Under a damages claim for breach of contract, the claimant must prove a breach, that the loss was caused by it, and that the loss was not too remote. Under a well-drafted indemnity, the trigger is simpler: if a loss falls within the clause's scope, the indemnified party is entitled to be paid, whether or not anyone breached the contract and whether or not the loss was foreseeable. That is what makes indemnities powerful, and why the drafting of the scope matters so much.

An indemnity is also distinct from a guarantee. A guarantee is a secondary promise: the guarantor answers for the default of someone else, usually the principal debtor. An indemnity is a primary promise: the indemnifier accepts responsibility in its own right and can be claimed against directly. This distinction matters in practice, which is why lenders and suppliers often ask company directors to sign a deed of guarantee and indemnity. The guarantee element backs the company's obligations; the indemnity element makes the director directly liable for the loss.

The Anatomy of an Indemnity Clause

Most indemnity clauses do four jobs, and each is a negotiation point:

• Scope: the types of loss covered, such as third-party claims, property damage, personal injury, IP infringement, regulatory fines or tax liabilities
• Triggers: the events that switch the indemnity on, such as negligence, breach of contract, a defective product or misuse of confidential information
• Exclusions and caps: what is carved out, such as indirect or consequential loss or the other party's negligence, and any financial ceiling on the indemnifier's exposure
• Procedures: how claims are notified and handled, including who controls the defence and whether settlements need approval

These choices determine what the clause is really worth. An indemnity for "all loss of any kind" with no cap, no exclusions and no procedures is a very different proposition from one limited to losses caused by your negligence, capped at a multiple of your fees, with you in control of the defence. The first is a blank cheque; the second is a measured allocation of risk.

How Australian Courts Read Indemnity Clauses

Australian courts do not give indemnity clauses a free pass. The High Court in Andar Transport Pty Ltd v Brambles Ltd (2004) 217 CLR 424 confirmed that indemnities are construed on ordinary principles of contractual interpretation, in the context of the whole contract. In BI (Contracting) Pty Ltd v AW Baulderstone Holdings [2007] NSWCA 173, the NSW Court of Appeal stressed that an indemnity clause is construed strictly in context, and where it is ambiguous, the ambiguity is resolved against the party relying on the clause. In Frewin v Adecco Industrial Pty Ltd [2015] NSWSC 1568, the court read a labour-hire supplier's indemnity in favour of the host company by reference to the context as it stood when the contract was made.

The most important practical consequence is this: a party seeking to be indemnified against the consequences of its own negligence needs clear words. Courts will not readily treat a general indemnity as covering the indemnified party's own carelessness, wilful misconduct or breach. If you are giving the indemnity, this is your friend: carve out the other side's negligence explicitly. If you are receiving it and want protection for your own conduct, the clause must say so.

There is a drafting lesson in all of this. Vague, catch-all language such as "all loss of any kind" does not buy certainty: it invites a dispute about what the parties actually intended. A clause that defines its scope, names its triggers and states its exclusions is far more likely to be enforced as written, and far less likely to end up in a fight over meaning.

Where Consumer Law Stops an Indemnity Dead

Indemnities cannot override mandatory consumer protections. Under s 64 of the Australian Consumer Law (the ACL, which is Schedule 2 of the Competition and Consumer Act 2010 (Cth)), a term of a contract is void to the extent it purports to exclude, restrict or modify the consumer guarantees, or liability for failing to comply with them. No indemnity, waiver or risk-shift clause can take away a consumer's right to a remedy for goods that are not of acceptable quality, and a clause that tries to push those losses onto the customer is void to that extent.

There is a business-to-business nuance. Under s 64A of the ACL, a supplier of goods or services that are not of a kind ordinarily acquired for personal, domestic or household use can limit its liability for failing to comply with most guarantees to repairing or replacing the goods, or re-supplying the services, provided the limitation is fair and reasonable in all the circumstances. This is a common and lawful way to cap exposure in commercial supply contracts, but it does not apply to consumer supplies.

Indemnities also face the unfair contract terms regime. Under ss 23 and 24 of the ACL, a term of a standard form consumer or small business contract is void if it is unfair: it causes a significant imbalance in the parties' rights and obligations, is not reasonably necessary to protect the legitimate interests of the party benefiting from it, and would cause detriment to the other party. A small business contract is one where at least one party employs fewer than 100 people or has a turnover under AUD 10 million. Since November 2023, proposing or relying on an unfair term is itself a contravention, and courts can impose penalties under s 224 of the ACL of up to the greater of AUD 100 million, three times the benefit obtained, or 30% of adjusted turnover for companies, and up to AUD 2.5 million for individuals. A one-sided, uncapped indemnity buried in a take-it-or-leave-it standard form agreement is exactly the kind of clause regulators and courts target.

A Worked Example: The Packaging Supplier's Indemnity

Put it together with a realistic scenario. You run a small business that prints packaging labels, and you have just won a contract with a large food retailer. The retailer's standard form supply agreement contains an indemnity: you agree to compensate the retailer for "all losses, costs, claims and expenses of any kind arising out of or in connection with the supply of the products".

A batch of your labels misprints the allergen information. A consumer has a reaction and sues the retailer; the retailer also recalls the affected stock and claims the recall costs, the value of the destroyed stock and its legal fees from you under the indemnity. Does the clause respond? The misprint arises out of the supply of the products, so the claim falls within the scope. You are on the hook for the defence costs, any settlement or judgment, and the recall costs, unless an exclusion saves you. There are none: the clause covers "any kind" of loss, it does not carve out losses caused by the retailer's own conduct (for example, if the retailer's warehouse mixed old and new stock), and there is no cap. Even the retailer's own handling of the recall could arguably be captured, and the claim is uncapped.

This is where negotiation happens, and a lawyer's checklist is straightforward: cap the indemnity at a sensible multiple of your annual fees; exclude losses caused by the retailer's acts or omissions; carve out indirect and consequential loss; add procedures requiring prompt notice, giving you control of the defence and the right to approve any settlement; and check that your public and product liability insurance actually responds. Many policies do not cover liabilities assumed by contract that go beyond your negligence, so the final wording should track what your insurer will fund. The same risk is allocated, but it is now measured, capped and insurable.

Common Misconceptions About Indemnities

A few misconceptions about indemnities cause the most trouble in practice:

• "An indemnity is the same as insurance": it is not. An indemnity is a promise between two parties; it pays nothing by itself. If you lack the cash to meet the promise, the other side is left chasing a company that cannot pay. Insurance is what actually funds a claim, and many policies exclude liability assumed under contract beyond your negligence, so the clause and the policy need to match.
• "An indemnity automatically covers my own negligence": only if the words clearly say so. Australian courts look for clear language before reading an indemnity as covering the indemnified party's own negligence, as the construction principles above show.
• "A broad indemnity is always enforceable": not necessarily. Courts read indemnities strictly and in context, and a one-sided, uncapped indemnity in a standard form small business contract can be an unfair term: void under the ACL, and now a basis for penalties against the business that proposed it.
• "The other side's indemnity means I am fully protected": only if the other party can actually pay. Where a counterparty is a small company with few assets, an indemnity is only as good as its balance sheet, which is why suppliers and lenders often take director guarantees or security as well.

When to Get a Lawyer to Review Your Indemnities

The value of legal review here is not about reading a single clause; it is about how the indemnity fits with the rest of the contract. A commercial lawyer will map the scope, triggers, exclusions, caps and procedures; check the indemnity against the limitation of liability clause and any consequential loss exclusion so one does not accidentally undo the other; test whether the wording is insurable; and advise on exposure under the ACL, including whether a standard form indemnity you have been asked to sign is vulnerable to an unfair terms challenge.

Done at signing stage, this is a document review that costs a fraction of what a dispute would. The practical payoff for a small business is smoother operations: the risk in the contract matches the risk you actually run, your insurance responds when a claim arrives, and you are not funding someone else's mistakes. If you are the business receiving a standard form indemnity, a lawyer can also tell you whether the clause is commercially fair or whether to push back, price the risk, or seek security for it.

The Question to Answer Before You Sign

Before you sign anything, be able to answer one question about every indemnity in the contract: if every risk in this clause materialised tomorrow, exactly what would I pay, to whom, and is my insurance ready to fund it? If your answer is "I am not sure what 'loss of any kind' covers", the clause is too vague to sign, and the gap will cost you later, not now. The businesses that get hurt by indemnities are rarely the ones that signed them; they are the ones that signed without knowing what the clause could cost them, and without checking whether their insurer would pay.
