What Are Primary and Noncontributory Endorsements?
A $250,000 claim can get complicated fast when more than one insurance policy is involved. If a subcontractor causes damage on a jobsite, should their insurance pay first? Can the general contractor’s policy be asked to contribute? And what happens if the contract required specific endorsement language, but no one verified it before work began?
That is where primary and noncontributory endorsements come in.
Smart businesses stay ahead of vendor and contractor risk by requesting a Certificate of Insurance (COI) from each third party they work with. But collecting the COI is only the first step. To stay compliant and avoid costly coverage gaps, teams also need to understand what the policy language actually means.
One area that causes a lot of confusion is primary and noncontributory wording. Below, we break down what these terms mean, how they affect insurance policies, and why verifying the endorsement matters before a claim puts it to the test.

Primary and Noncontributory Endorsements: Why Are They Important?
Imagine this: you hire a subcontractor for a job, and someone gets hurt on the worksite. Who should be held accountable for the damages? It’s a complicated situation, right?
That’s where primary and noncontributory endorsements come into play. These endorsements determine the order in which insurance policies pay for damages or losses resulting from an incident.
Basically, these endorsements are added to a business’s liability policies — most commonly general liability, commercial auto, and umbrella or excess liability. Workers’ compensation works differently: it doesn’t accept additional insureds or primary and noncontributory wording. The closest equivalent is a waiver of subrogation.

What are Primary and Noncontributory Endorsements?
A primary endorsement establishes which insurance policy responds first to a covered claim. It doesn’t decide who was at fault. It decides whose coverage pays before any other policy is asked to step in.
A noncontributory endorsement prevents the primary insurer from asking another party’s insurance to chip in on the same claim. In a typical contractor relationship, it means the subcontractor’s insurer can’t seek contribution from the general contractor’s policy, even though the general contractor has coverage of its own.
Together, primary and noncontributory wording keeps a claim with the policy of the party whose work created the risk, which is exactly why upstream parties require it.
Primary and noncontributory endorsements go hand-in-hand with COIs. They not only lay out the responsible party for insurance claims but also outline which party will not be responsible for certain claims.
| What It Does | Explanation | Why It Matters | |
| Primary Endorsement | Establishes which insurance policy responds first to a covered claim. | One party’s insurance takes the first turn paying for the claim before another policy is used. | Helps clarify responsibility upfront and reduces confusion over whose coverage applies first. |
| Noncontributory Endorsement | Prevents the primary insurer from seeking contribution from another party’s insurance policy. | The first policy cannot ask the other party’s policy to help pay for the same claim. | Helps protect the upstream party’s insurance from being pulled into a claim that should be handled by the responsible party’s policy. |
Examples of Primary and Noncontributory Language Requirements
Understanding how insurance and COIs work in complex situations can be tricky.
Let’s take a hypothetical scenario for example: a business hires a general contractor to build a new office space on empty land. This general contractor hires subcontractors for specific tasks, like plumbing and electrical.
Before the project begins, the business owner and general contractor will agree on the insurance policy requirements for both the contractor and subcontractor. In most cases, the contract will state that the business needs to be named as an additional insured with primary and noncontributory coverage.
Now, let’s say that during construction, someone walking by the building gets hurt due to the negligence of one of the subcontractors. The injured person decides to sue the business owner, the general contractor, and the subcontractor.
Here’s where the primary and noncontributory language in the insurance policies and contracts becomes crucial. It determines who will be responsible for paying the damages.
In this case, the subcontractor’s insurance policy will cover the initial damages from the lawsuit. If their coverage is not enough to cover the damages, then the business and/or general contractor’s policies will kick in.
Typically, the construction contract specifies that the general contractor’s policy will cover any remaining damages up to its coverage limits before the business’ insurance has to contribute.
Unlimited Liability Insurance
Certain business structures don’t set limits on what can be done to satisfy business debts. This could come into play if there were an expensive claim against the business. How the business is structured — and what insurance policies the business has — determines whether the owner of the business would be personally liable for the damages.
Contribution—In General
Unlimited liability companies are typically defined as sole proprietorships in the United States. These business entities do not shelter an owner from liability to pay the business’ debts.
This means the owner could be personally responsible for paying business-related claims, should the business not have the assets to cover them.
Contribution—In Insurance
This also applies to insurance. If an insurance policy for the ULC has reached its coverage limit, the owner could be personally responsible for paying for the remainder of the damages. This might force the owner to liquidate the business and/or use their own personal savings or assets to pay for it.
Non-ISO Additional Insured Endorsements
The Insurance Services Office (ISO) publishes the standardized policy and endorsement forms most of the industry builds on. For primary and noncontributory coverage, the standard form is CG 20 01 04 13 (Primary and Noncontributory — Other Insurance Condition). It makes additional insured coverage primary and noncontributory, but only when two conditions are met: the additional insured is a named insured on its own separate policy, and a written contract requires the coverage to apply on a primary and noncontributory basis.
Not every insurer uses ISO forms. Many issue proprietary endorsements with their own wording, and that wording can be narrower than the contract requires, limiting the trigger, the scope of operations covered, or the noncontributory language itself.
Priority of Coverage
This is why verification matters. Two endorsements can both be described as “primary and noncontributory” on a COI while behaving very differently in a claim. The priority of coverage is set by the actual endorsement language, so teams should review the endorsement itself, not just the certificate, and confirm it matches the contract.
Priority of Coverage
The priority of coverage is determined by additional insured endorsements and primary and noncontributory endorsements in insurance policies. This means one company’s policy takes the hit for damages from a claim before the other company’s policy kicks in.
Primary and Noncontributory Endorsements vs. Waiver of Subrogation
Primary and noncontributory endorsements and waivers of subrogation are both common insurance requirements in construction contracts, vendor agreements, and other third-party relationships. They are often requested together, but they do not do the same thing.
A primary and noncontributory endorsement deals with which insurance policy responds first when there is a covered claim. If a subcontractor’s policy is primary and noncontributory, that policy should pay before the general contractor’s or project owner’s policy is asked to contribute. This helps keep the financial responsibility with the party whose work or operations created the risk.
A waiver of subrogation deals with what happens after a claim has already been paid. Normally, an insurance company may have the right to pursue another party to recover the money it paid on a claim. A waiver of subrogation limits that right. In plain English, the insurer agrees not to turn around and seek reimbursement from the other party named in the contract.
The easiest way to think about the difference is this:
Primary and noncontributory wording determines the order of payment. Waiver of subrogation limits the insurer’s ability to recover payment later.
For example, if a subcontractor causes damage on a jobsite, the general contractor may expect the subcontractor’s insurance to respond first because the contract requires primary and noncontributory coverage. If that same contract also includes a waiver of subrogation, the subcontractor’s insurer may also be prevented from trying to recover claim payments from the general contractor after the loss.
Both requirements are designed to reduce risk and prevent coverage disputes. But they need to be verified separately. A COI may reference one requirement without proving the other is actually included in the policy. That is why teams should review the underlying endorsements, not just the COI.
Releases and Waivers of Subrogation
Waivers of subrogation are covered in more detail above, but the key point bears repeating: subrogation is an insurer’s right to recover a claim payment from the party that caused the loss, not from that party’s insurance company. A waiver of subrogation gives up that recovery right against a specific party named in the contract. It works alongside primary and noncontributory wording, but it solves a different problem: P&N controls who pays first, while a waiver of subrogation controls who can be pursued afterward.
Other Insurance Condition—General
Why “Noncontributory” Was Added
Under the standard CGL “other insurance” condition, a policy covering an additional insured is generally primary. The catch: the additional insured’s own policy is also primary for that same claim. Historically, that overlap let the downstream party’s insurer demand that the additional insured’s policy share the loss, defeating the purpose of requiring additional insured status in the first place.
“Noncontributory” wording was developed to close that gap. It confirms that the policy will pay without seeking contribution from the additional insured’s other available insurance, keeping the full claim with the party whose operations created the risk.
Follow Form Umbrella or Excess Liability Policy
Follow-form insurance helps to provide coverage that is consistent for any excess liability policy. Follow-form umbrella policies provide excess coverage within the same terms as the original policy.
This comes into play whenever a claim exceeds the coverage amount of the original policy, as the example above illustrates.

Frequently Asked Questions
What does primary and noncontributory mean in plain English?
Primary and noncontributory means one party’s insurance responds first if there is a covered claim, without asking another party’s insurance to help pay. In a contractor relationship, this usually means the subcontractor’s policy pays before the general contractor’s policy. It helps clarify responsibility upfront and reduces the risk of coverage disputes when a claim occurs.
What is the difference between primary and noncontributory and waiver of subrogation?
Primary and noncontributory wording determines which insurance policy responds first and whether another policy has to contribute. A waiver of subrogation is different. It prevents an insurance company from trying to recover claim payments from another party after a loss.
Why do general contractors require primary and noncontributory wording?
General contractors require primary and noncontributory wording to help protect their own insurance from being pulled into claims caused by subcontractor work. If a subcontractor’s actions lead to a covered loss, the subcontractor’s policy should respond first. This helps reduce claim disputes, protect the general contractor’s loss history, and keep project risk where the contract intended it to be.
What form is used to add primary and noncontributory coverage?
Primary and noncontributory coverage is usually added through an endorsement to the insurance policy. Typically ISO CG 20 01 04 13 (Primary and Noncontributory — Other Insurance Condition), but because forms are not all the same, teams should verify the endorsement itself instead of relying only on the certificate of insurance.
Can a subcontractor refuse to provide a primary and noncontributory endorsement?
A subcontractor can refuse, but that may put them out of compliance with the contract. If the contract requires primary and noncontributory wording, the subcontractor usually needs to secure the proper endorsement before work begins. In some cases, the insurer may not offer the requested wording, which is why verification should happen early enough to resolve issues before they create project delays.
Do primary and noncontributory affect insurance premiums?
It can. Adding primary and noncontributory wording may affect premiums depending on the insurer, policy, coverage limits, type of work, and risk involved. Some endorsements may be included, while others may require an additional charge. The bigger issue for hiring parties is not just whether the endorsement exists, but whether it matches the contract requirements and is verified before work begins.
