Anti-indemnity statutes are state laws that prevent a contract from forcing one party to pay for another party’s own negligence. About 45 states have enacted some version, most aimed at construction contracts, and they sort fault into three categories that decide whether a given indemnity clause survives: sole negligence, active negligence, and passive negligence. The category the facts fall into determines whether a court enforces the clause, trims it, or throws it out entirely.
The Three Indemnity Forms the Statutes Regulate
Every indemnity clause in a construction contract takes one of three shapes, and the shape controls how much statutory scrutiny it draws.
- Broad form. The indemnitor covers all losses regardless of who caused them, including the indemnitee’s sole negligence. If a general contractor is 100% at fault, the subcontractor still pays. This is the most aggressive form of risk transfer and the primary target of anti-indemnity legislation.
- Intermediate form. The indemnitor covers losses unless the indemnitee is solely at fault. A subcontractor even 1% at fault could end up paying the full judgment, including the 99% caused by the general contractor. Some states divide this into full and partial versions, with the partial version capping the indemnitor’s liability at its actual share of fault.
- Limited form. Each party pays for its own share of negligence. A subcontractor found 60% at fault pays 60% of the damages. Every state allows limited form indemnity because nobody is picking up someone else’s negligence.
The broader the form, the more likely a statute will void it. Broad form clauses are the main target. Intermediate form clauses survive in some states but not others. Limited form clauses are universally enforceable.
Sole Negligence
Sole negligence means one party holds 100% of the fault. Anti-indemnity statutes in nearly every state forbid contracts that force another party to pay when a single party is entirely responsible. This is the least controversial application of these laws and carries the broadest agreement across jurisdictions.
The reasoning is direct. A party that knows it will never pay for its own total carelessness has weakened incentives to prevent accidents. If a general contractor can guarantee through contract language that a subcontractor’s insurer will pay even when the general contractor alone caused the harm, the general contractor’s motivation to keep the site safe erodes. The statutes preserve that accountability by making broad form clauses unenforceable.
Courts enforcing these laws do not always rewrite an overreaching clause into something reasonable. In many jurisdictions, a clause that tries to cover sole negligence can be voided in its entirety, stripping the party of all contractual indemnity protection. A company that reached for total protection can end up with none. That all-or-nothing risk is one of the strongest practical reasons to draft indemnity language that respects statutory boundaries.
Active Negligence
Active negligence is a specific affirmative act that directly causes harm. A contractor knowingly providing defective equipment, a supervisor ordering workers into an unsafe area without protective gear, a project manager physically directing operations in a way that causes a collapse — these all qualify. The common thread is personal participation in creating the danger rather than a failure to notice it.
Many states treat active negligence the way they treat sole negligence for indemnity purposes. Someone who personally created a hazard should not escape the financial consequences through a contract clause any more than someone who was entirely at fault. Intermediate form clauses often try to reach these scenarios, and statutes frequently block them when the party seeking protection actively contributed to the injury.
The distinction between active and passive negligence matters most in states that allow some degree of intermediate indemnity. There, a party that merely failed to catch a problem may be able to shift costs contractually, but a party that affirmatively created the problem cannot. This is where indemnity disputes get expensive and fact-intensive. The line between doing something wrong and failing to prevent something wrong often depends on close examination of what each party actually did on-site.
Passive Negligence
Passive negligence is an omission rather than an act. Failing to discover a hazardous condition during a routine inspection, neglecting to enforce safety protocols, or simply not noticing a defect that a more diligent party would have caught all qualify. The law generally views these failures as less blameworthy than active participation in creating danger.
That lower level of culpability shows up in how anti-indemnity statutes handle passive negligence. Under limited and some intermediate form agreements, a party may still contractually shift costs associated with its own passive negligence to the party that primarily caused the harm. If a subcontractor creates a hazard and the general contractor simply fails to spot it during a walk-through, the subcontractor often remains on the hook for the full damages. Courts uphold these arrangements because they do not shield a party from the consequences of its own intentional or direct errors.
Passive versus active is also where most litigation happens. A general contractor will argue its role was merely supervisory and any failure to catch the problem was passive. The subcontractor will argue the general contractor’s decisions about scheduling, staffing, or safety equipment amounted to active participation. Courts in comparative fault states have to sort out not just who was negligent, but what kind of negligence each party committed, because the classification decides whether the indemnity clause applies at all.
What Happens When a Clause Violates the Statute
The consequences of an anti-indemnity violation depend heavily on how the clause was drafted. Courts generally take one of two approaches. They void the entire indemnity provision, or they strike only the offending portion and enforce the rest.
The safest drafting technique is to begin the clause with language like “to the fullest extent permitted by law.” That phrase signals to a court that the parties intended the clause to operate at the maximum level the statute allows, and that if part of it overreaches, the rest should survive. Courts that see this language tend to strike the impermissible portion and enforce the balance. Without it, many courts void the entire clause, reasoning that the parties intended the provision as a single, indivisible package.
The practical fallout of a voided clause is severe. A general contractor that expected its subcontractor’s indemnity obligation to cover a major jobsite injury suddenly has no contractual right to reimbursement. The related insurance requirements, including additional insured endorsements, may collapse alongside it because they are treated as extensions of the underlying indemnity agreement. What looked like a comprehensive risk management strategy on paper becomes an unfunded liability overnight.
Insurance Requirements Ride Along With the Clause
Anti-indemnity statutes do not just affect the indemnity clause itself. They reach into the insurance requirements that typically accompany those clauses. Construction contracts routinely require subcontractors to name the general contractor as an additional insured on their commercial general liability policy, effectively creating a backup for the indemnity obligation. If the underlying indemnity clause is void, the insurance requirement built on top of it may be void as well.
Several states explicitly equate an agreement to provide insurance with an agreement to indemnify. In those jurisdictions, requiring a subcontractor to provide additional insured coverage for the general contractor’s own sole negligence is just as unenforceable as a broad form indemnity clause attempting the same thing. The statute views the insurance arrangement as an end-run around the indemnity prohibition and shuts it down accordingly.
How Standard Endorsements Adapted
The insurance industry responded to the patchwork of state laws by building compliance language directly into standard policy endorsements. Rather than creating separate forms for each state, current additional insured endorsements include the phrase “the insurance afforded to such additional insured only applies to the extent permitted by law.” That language automatically limits coverage to whatever the applicable state statute allows, preventing the endorsement from providing coverage the anti-indemnity law prohibits.
The endorsements also include two further restrictions. Coverage for the additional insured cannot be broader than what the underlying contract requires, and the insurer’s payment is capped at the lesser of the policy limit or the limit specified in the contract. The actual coverage an additional insured receives can be significantly narrower than what the contract appeared to promise, especially in states with aggressive anti-indemnity statutes.
Industry Carve-Outs
Most anti-indemnity statutes apply to construction contracts, typically defined to include building, alteration, repair, maintenance, demolition, and excavation. The scope varies, and several industries have their own rules.
Oilfield Operations
At least four states have enacted oilfield-specific anti-indemnity legislation separate from their general construction statutes. These laws address the master service agreements used throughout the oil and gas industry, where operators routinely require service companies to assume sweeping indemnity obligations. The oilfield statutes generally void indemnity clauses that cover the operator’s own negligence, but the details differ. Some expressly prohibit additional insured requirements and waivers of subrogation. Others are silent on insurance provisions, leaving room for the same risk transfer the statute was designed to prevent.
Knock-for-Knock Agreements
Knock-for-knock indemnity is a mutual arrangement common in the energy sector. Each party assumes liability for injuries to its own employees and damage to its own property, regardless of fault. You insure your people, I insure mine, and neither of us fights over who caused what. This lines up contractual responsibility with existing insurance coverage and avoids litigating fault on every incident.
Whether knock-for-knock agreements survive anti-indemnity statutes depends on the jurisdiction and the specific statute. Some state oilfield anti-indemnity acts carve out an exception for mutual indemnity obligations, provided each party maintains insurance to back its commitment. Construction anti-indemnity statutes, which typically focus on one-directional risk transfer, may void the same arrangement because each party is technically agreeing to indemnify the other’s negligence. The enforceability of a knock-for-knock clause can turn entirely on which statute applies.
Passenger Rail
Federal law creates a significant exception for passenger rail operations. Under 49 U.S.C. § 28103, providers of rail passenger transportation may enter into contracts that allocate financial responsibility for claims, and federal courts have held that this provision preempts state anti-indemnity statutes that would otherwise prohibit such agreements. A railroad can contractually require a contractor to indemnify the railroad for the railroad’s own negligence in situations where a construction anti-indemnity statute would void the same clause. Federal regulators recognize one limit: indemnification for gross negligence or willful misconduct remains contrary to public policy even under the federal framework.
Contracts Outside Traditional Construction
Anti-indemnity statutes generally apply to traditional construction-related parties: contractors, subcontractors, engineers, and architects. Agreements between parties outside that universe may fall outside the statute’s reach entirely. Courts have held, for example, that a hold-harmless agreement between a tenant and a landlord for maintenance work does not trigger construction anti-indemnity protections, even though the work itself involved physical labor on a building. Professional services contracts, equipment leases, and vendor agreements are similarly outside the scope of most construction-focused statutes. Broad form indemnity clauses in those contracts may be enforceable even in states that ban them for construction.
How Comparative Fault Changes the Math
Anti-indemnity statutes and comparative fault systems answer different questions on the same jobsite. Comparative fault determines how much of the total damages each party owes based on its percentage of responsibility. Anti-indemnity statutes determine whether one party can contractually require another to pay more than its fair share.
The tension shows up in intermediate form clauses. In a comparative fault state, a jury might find the general contractor 70% at fault and the subcontractor 30% at fault. Without an indemnity clause, each party pays its percentage. With an intermediate form clause, the subcontractor could be contractually required to cover the general contractor’s 70% share as well, because the subcontractor was at least partially at fault. Anti-indemnity statutes in some states block this result by voiding clauses that require indemnification when the indemnitee bears any comparative fault. Others allow it as long as the indemnitee was not solely at fault. The same contract clause produces radically different outcomes depending on where the project is located.
Indemnity language has to be tailored to how the applicable state allocates fault. A clause drafted for a state that only prohibits sole-negligence indemnity will overreach in a state that prohibits indemnity whenever the indemnitee is comparatively at fault. Because large construction projects frequently span multiple jurisdictions or involve parties from different states, this is one of the areas where blanket contract language most often fails.
