Anti-indemnity statutes in construction contracts are state laws, now on the books in roughly 43 states, that void or limit clauses forcing one party to pay for losses caused by another party’s negligence. The specifics vary by jurisdiction, but the principle is consistent across them: a party that causes harm should bear the cost of that harm, not push it down the contracting chain through fine print. If your contract contains an indemnity clause that crosses the line a given state has drawn, the clause is unenforceable, and the party counting on that protection loses it.
The Three Forms of Indemnity
Every indemnity clause in a construction contract falls into one of three categories, and the category decides whether the clause survives.
Broad form makes the indemnitor responsible for all liability, including losses caused entirely by the indemnitee. A subcontractor who signs a broad form clause can be forced to pay the full judgment for an accident the general contractor caused by itself. Most states with anti-indemnity statutes void broad form clauses outright.
Intermediate form makes the indemnitor responsible for everything unless the indemnitee was solely at fault. In practice, a subcontractor who contributed one percent to an accident can end up paying one hundred percent of the damages. A smaller but significant group of states prohibit intermediate form clauses as well, often with stricter rules on public projects.
Limited form makes each party pay only for its own share of the fault. This tracks comparative fault, and every state allows it. When a court strikes down a broader clause, the parties’ obligations usually default to this proportional standard.
The distinction matters at drafting, not after a lawsuit is filed. A clause that reads reasonably in negotiation can become unenforceable the moment it slips from limited into intermediate or broad territory.
What Happens When a Clause Is Voided
The typical consequence is simple: the clause is unenforceable, and the party that drafted it loses the protection it thought it had. Courts generally do not fine or sanction the drafter. The punishment is the loss of the indemnity itself. Whoever expected to shift risk is left paying its own defense costs and any judgment tied to its own negligence.
Whether the rest of the contract survives depends on how it was drafted. Most construction contracts contain a severability clause, which lets a court strike only the offending language and leave everything else intact. Without one, there is a theoretical risk the whole agreement could be affected, though courts generally prefer to preserve the parties’ bargain.
One drafting trap worth flagging: if the indemnity obligation and the duty to defend sit inside the same paragraph, voiding the paragraph can take the defense obligation with it. Parties who want the defense obligation to survive should give it its own section.
The Express Negligence Doctrine
Even where a state permits some risk transfer, the contract language has to clear a high bar. Many jurisdictions apply the express negligence doctrine, which requires any clause shifting liability for a party’s own negligence to say so in unmistakable terms. Vague or general language will not do the job, even if a lawyer could argue it covers negligence.
Two requirements usually apply. First, the clause must state expressly that the indemnitor is covering losses caused by the indemnitee’s own negligence. Inference is not enough. Second, the clause must be conspicuous, set apart through bold type, larger font, capitalization, or some other visual signal a reasonable person would notice. A negligence-shifting clause buried in standard text in a long contract can fail on conspicuousness alone.
This catches parties off guard regularly. A general contractor may believe its indemnity clause covers every scenario, then learn in litigation that it never specifically mentioned negligence and provides no protection at all.
Duty to Defend and Duty to Indemnify Are Different
These two obligations are legally distinct. The duty to indemnify applies after a party is found liable and covers the final judgment or settlement. The duty to defend is triggered the moment allegations are raised and pays for legal representation throughout the case. It is also broader: it applies to every claim that even arguably falls within the indemnity agreement, and it can exist regardless of whether the underlying claims have merit. A meritless lawsuit still needs a lawyer, and the duty to defend pays for one.
Courts are split on whether voiding an indemnity clause also kills the associated duty to defend. Some treat the two as inseparable, so if the indemnity falls, the defense obligation falls with it. Others let the duty to defend stand on its own, especially when the contract treats it as a separate obligation. The safer draft keeps the duty to defend in its own provision with its own defined scope.
Insurance Requirements and Additional Insured Clauses
Anti-indemnity statutes do not operate in isolation. They collide with insurance requirements, and the collision produces a second layer of risk. The common pattern: a general contractor can no longer legally require a subcontractor to indemnify it for its own negligence, so it instead requires the subcontractor to name it as an additional insured on the subcontractor’s liability policy. If the insurance delivers the same protection the voided indemnity would have, is the insurance requirement also illegal?
States answer differently. A handful, including Arizona, Colorado, Georgia, Kansas, Montana, and Oregon, explicitly void additional insured coverage for the indemnitee’s sole negligence, reasoning that an agreement to insure is functionally the same as an agreement to indemnify. Other states have concluded that their anti-indemnity statutes apply only to indemnity agreements and do not reach insurance requirements, even when the practical effect is identical. A few take a middle path, allowing additional insured requirements only when the coverage tracks the indemnitor’s own negligence or sits in a separately priced policy.
The underlying question in every jurisdiction is the same: does the insurance requirement work as a backdoor around the statute, or as an independent risk-management tool? The answer determines whether the backup plan actually works.
Choice-of-Law Clauses Usually Will Not Save a Bad Clause
One tactic parties try is drafting the contract to be governed by the law of a state with weaker protections. If the project sits in a state that voids broad form indemnity, but the contract names a friendlier state’s law, which one controls?
A growing number of states have anticipated this and enacted anti-choice-of-law provisions aimed specifically at construction contracts. If the project is physically located inside the state, any clause forcing another state’s law to apply is void or voidable. Some statutes also prohibit requiring litigation or arbitration elsewhere. The project’s home state keeps control.
Even without a specific statute, courts can refuse to honor a choice-of-law clause on public policy grounds. When applying the chosen state’s law would violate a fundamental policy of the state where the project sits, courts generally apply local law. Relying on a choice-of-law clause to rescue an otherwise void indemnity provision is a significant gamble.
Which Contracts Are Covered
Anti-indemnity statutes reach broadly across construction-related agreements. The typical statute covers contracts for new construction, renovation, repair, maintenance, demolition, excavation, and site preparation. Many states also extend coverage to professional services, so contracts with architects, engineers, and design consultants fall under the same restrictions even though no physical construction work is involved.
Coverage runs down every tier of the chain. Prime contracts between owners and generals, subcontracts, and sub-subcontracts all have to comply. Collateral agreements tied to project work, such as consulting agreements or project-related purchase orders, can also be swept in. If an agreement relates to the improvement of real property or the design of it, it should be evaluated against the statute.
Some statutes split public and private work, with stricter rules on government-funded projects, and a few states limit their statutes to residential construction or to specific contract types. Checking the statute that fits your project type matters more than relying on general rules.
Knock-for-Knock and Workers’ Compensation Waivers
Two arrangements sit at the edge of these statutes and often surprise people. Knock-for-knock indemnity is common in energy and heavy construction. Instead of allocating liability by fault, each party agrees to cover injuries and damage to its own employees and property, regardless of who caused the loss. The appeal is reduced litigation, since nobody argues fault percentages. But many jurisdictions treat these arrangements skeptically because they can force a party to absorb losses caused by someone else’s negligence, which is the result anti-indemnity statutes exist to prevent. Some states allow knock-for-knock for personal injury but not property damage. Others require the obligation to be backed by insurance of a specified amount. Specific oilfield anti-indemnity acts may provide safe harbors when liability coverage supports the obligation. Assuming a knock-for-knock clause works without checking local law is a reliable way to end up with no protection.
Workers’ compensation waivers of subrogation are the other common edge case. These waivers prevent an insurer that pays a comp claim from suing another party to recover. On the surface they resemble indemnity, because they shield a potentially negligent party from financial consequences. Most jurisdictions that have addressed the question treat them as different from indemnity: a waiver allocates risk between the contracting parties and their insurers rather than transferring negligence liability. Several states explicitly exempt workers’ compensation and insurance contracts from their anti-indemnity statutes. The line between allocating insurance risk and indemnifying against negligence is not always clean, and the law continues to develop.
Reading an Indemnity Clause Before You Sign
Knowing these statutes exist helps only if you can spot the problems before signing. Start by identifying which form of indemnity the clause requires. Phrases like “any and all claims” or “regardless of fault” signal broad form. Language limiting indemnity “to the extent caused by” the indemnitor’s negligence signals limited form. Anything in between deserves close scrutiny.
Then check whether the clause addresses the indemnitee’s own negligence, and if so, whether the language meets the express negligence doctrine in your jurisdiction. A clause that only implies coverage of the indemnitee’s negligence can be unenforceable even where intermediate form indemnity is otherwise permitted.
Look at the scope of parties covered. Some clauses require the subcontractor to indemnify the general contractor, the owner, the architect, the engineer, and their agents and successors. Each added party expands exposure and has to be evaluated separately against the statute.
Finally, read the insurance obligations alongside the indemnity. If the indemnity itself is likely void, an additional insured requirement designed to produce the same result may be unenforceable too, depending on your state. Contracts that keep the insurance obligation separate from the indemnity obligation, and tie additional insured coverage to the indemnitor’s own negligence, are more likely to survive challenge than ones that simply mirror the scope of a prohibited indemnity clause.
