A construction contract often arrives with insurance requirements: name one party as a certificate holder, add another as an additional insured, carry primary and noncontributory coverage, include a waiver of subrogation. Understanding additional insured vs certificate holder is where the confusion usually starts, because the two sound alike but do very different things. For contractors and subcontractors across Indiana, Kentucky, and Illinois, sorting it out before work begins keeps a paper certificate from standing in for coverage you only thought you had.
Key Takeaways
- A certificate holder receives proof a policy exists but gets no coverage and, on that basis alone, cannot file a claim or demand a defense.
- An additional insured is added to the other party’s policy by endorsement, which lets it tender its defense and access coverage for claims arising out of the named insured’s work.
- A certificate of insurance is informational only; additional insured status or a waiver of subrogation requires the policy itself to be endorsed, not just a note on the certificate.
- For general liability, additional insured status uses ISO forms CG 20 10 (ongoing operations) and CG 20 37 (completed operations); confirm completed operations if your work ends before a claim could surface.
- Workers’ compensation and professional liability policies cannot add an additional insured, so a waiver of subrogation is used there, checked line by line.
- In Indiana, a construction contract clause indemnifying a party for its own sole negligence is void under Indiana Code 26-2-5-1 (highway contracts excepted).
Certificate Holder vs. Additional Insured: Proof Versus Protection
The difference comes down to proof versus protection. A certificate holder receives a certificate of insurance as proof that a policy exists, but gets no coverage from it. An additional insured is actually added to the other party’s policy, so it can access that coverage and tender a legal defense to the insurer. One is a receipt. The other is coverage.
Adding an additional insured, making coverage primary and noncontributory, and waiving subrogation all happen by endorsement, a formal change to the policy itself and not a line typed onto a certificate. That single fact is where much of the confusion starts, and it is why the four requirements get tangled together. They are commonly used interchangeably and lumped together as though they are a single concept. The table below shows what each does, how it is added, and what to check before you sign.
| Term | What it does for the other party | How it is added | What to verify before you sign |
|---|---|---|---|
| Certificate holder | Receives the certificate of insurance (COI) as proof that coverage exists. Gets no coverage and cannot make a claim or demand a defense under the policy on that basis alone. | Listed in the Certificate Holder box on the ACORD 25. No endorsement to the policy is involved. | That being listed here is all the contract truly requires. On its own it is evidence only, not protection. |
| Additional insured | Actually added to the named insured’s policy, so it can tender its defense to that insurer and access coverage for claims arising out of the named insured’s work. | By endorsement to the policy. For general liability, the ISO forms are CG 20 10 (ongoing operations) and CG 20 37 (completed operations). | Ask for the endorsement, not just the certificate. Confirm it covers completed operations if your work will be done before a claim could arise. |
| Primary and noncontributory | Your policy is intended to pay first on a covered claim, and your insurer will not ask the other party’s insurer to contribute. | By endorsement. A statement on the certificate does not create it in lieu of the endorsement. | Confirm the endorsement language. Upstream parties such as general contractors and owners routinely require this alongside additional insured status. |
| Waiver of subrogation | Gives up your insurer’s right to recover its payout from the other party after it pays a covered claim. | By endorsement on the relevant line (general liability, workers’ compensation, auto, property). A blanket waiver endorsement may apply. Workers’ comp and professional liability policies do not offer additional insured status, so a waiver is the tool that fits there. | Check it coverage line by coverage line. A waiver shown on one policy does not automatically apply to every policy. |
What Is a Certificate Holder?
A certificate holder is the party named on a certificate of insurance so it has proof that coverage exists. It is not added to the policy, so on that basis alone it cannot file a claim or demand a defense.
A certificate of insurance (COI) is the one-page summary of a policy, usually issued on the standardized ACORD 25 form; our guide to what a certificate of insurance is covers it in full. The form is blunt about its limits: the ACORD 25 states it confers no rights upon the certificate holder and does not amend or extend the policy. If the holder is meant to be an additional insured, or subrogation is to be waived, the policy must say so by endorsement.
What Is an Additional Insured, and How Is It Added?
An additional insured is a person or business added to another party’s policy by endorsement. Once the endorsement is in place, it can tender its defense to that insurer and access coverage for claims arising out of the named insured’s work. That is the protection a certificate alone never provides.
For a general liability policy, the coverage that responds to third-party bodily injury and property damage, additional insured status is added with specific ISO endorsements. The two you see most often are CG 20 10 for ongoing operations and CG 20 37 for completed operations. The split matters: ongoing operations covers work in progress, while completed operations covers the period after a job is finished, which is often when a construction defect claim surfaces. If your work wraps up before a claim could arise, confirm the endorsement includes completed operations.
There is also a ceiling. Since the 2019 ISO revisions, these endorsements limit coverage to the lesser of the amount required by the contract or the policy’s available limit, so the other party never gets more coverage than the contract calls for.
Which Policies Cannot Add an Additional Insured
Not every policy can name an additional insured. Workers’ compensation and professional liability policies do not offer additional insured status, which is easy to miss when a contract asks for it across the board. For a workers’ compensation policy, the tool that fits instead is a waiver of subrogation, covered below. Professional liability (errors and omissions coverage) works the same way.
Primary and Noncontributory: Making Sure Your Policy Pays First
Primary and noncontributory means your policy is intended to pay first on a covered claim, and your insurer will not ask the other party’s insurer to chip in. General contractors and owners routinely require it alongside additional insured status. Like that status, it is created by endorsement, not by a line on the certificate, so ask your agent to confirm the endorsement language is actually on the policy.
Waiver of Subrogation: What It Gives Up and Where It Applies
A waiver of subrogation gives up your insurer’s right to recover its payout from the other party after it pays a covered claim. Subrogation is the process where one party takes over another’s legal rights, so after paying a claim your insurer can normally step into your shoes and pursue whoever caused the loss. A waiver signs that right away for the party named in the contract.
A waiver is added by endorsement and applies line by line. A blanket waiver endorsement may cover several policies at once, but you cannot assume it does: a waiver on your general liability policy does not automatically apply to your commercial auto or workers’ compensation coverage. This is also why a waiver shows up so often on workers’ comp, where an additional insured cannot be added.
How Indiana’s Anti-Indemnity Law Limits Risk Transfer
There is a limit to how far a contract can shift your own liability onto someone else, at least in Indiana. Under Indiana Code 26-2-5-1, a clause in a construction or design contract that indemnifies a party against liability for its own sole negligence or willful misconduct is against public policy and unenforceable. Highway contracts are the exception.
The statute draws a careful line. Sole negligence does not include vicarious liability, imputed negligence, or the assumption of a nondelegable duty, so most ordinary risk transfer through additional insured status and waivers stays valid. Indiana’s statute is specific to Indiana, and Kentucky and Illinois apply their own laws, so the same clause can land differently depending on where the work is done. This anti-indemnity limit is one piece of the broader set of Indiana small business insurance requirements that shape what a contract can ask you to carry. This is general information, not legal advice; for a specific contract, talk with your agent and, where the stakes call for it, an attorney licensed in that state.
What to Verify Before You Sign
Before you sign a contract with insurance requirements, walk through a short checklist with your agent. It turns vague contract language into specific endorsements you can confirm are in place.
- Match the words to the mechanism. Additional insured means an endorsement, not just a spot in the certificate holder box. If it says certificate holder, confirm that really is all it requires.
- Ask for the endorsement, not just the certificate. Request the actual additional insured, primary and noncontributory, and waiver endorsements, and confirm the forms match the contract.
- Check completed operations. Make sure additional insured coverage includes it if your work finishes before a claim could surface.
- Go line by line on waivers. Confirm each waiver of subrogation is on the specific policy the contract names.
- Confirm your limits, including any umbrella. If the contract requires high limits, an umbrella or excess policy may sit above your general liability, and the requirement may need to be met on that layer too rather than assumed to carry up from the primary policy.
- Mind the timing. Endorsements should be in place before work starts, since a certificate reflects coverage only as of the day it is issued.
Three Situations Where This Comes Up in the Tri-State
The same distinction plays out differently depending on where you sit on the job.
- A subcontractor hired by a general contractor: The GC usually requires additional insured status, primary and noncontributory coverage, and often a waiver on your general liability, sometimes on auto and workers’ comp too. Certificate-holder status alone does not satisfy that.
- A vendor or contractor on a leased property: The owner and the tenant may both need to be named, and each may want additional insured status rather than only certificate holder.
- A landlord requiring coverage from a tenant’s contractor: If you are the one requiring the coverage, ask for the endorsements, not only the certificate, so you actually hold the protection you want.

Frequently Asked Questions About Additional Insured vs. Certificate Holder
Does certificate holder mean additional insured?
No. A certificate holder simply receives proof that a policy exists. An additional insured has been added to the policy by endorsement and can access coverage and a defense, so certificate-holder status does not satisfy a contract that asks for additional insured status.
How do I confirm I’ve actually been added as an additional insured?
Ask for a copy of the additional insured endorsement, not just the certificate. For general liability, look for forms such as CG 20 10 and CG 20 37, and confirm completed operations is included if your work finishes before a claim could arise.
Does a waiver of subrogation apply to all of my policies?
No. A waiver applies line by line, on the specific policy it is endorsed to. A waiver on your general liability does not automatically apply to your commercial auto, workers’ compensation, or property coverage, so confirm it is on each line the contract names.
Does adding an additional insured or a waiver cost extra?
It depends on the policy and the carrier. These endorsements are added to the policy, and whether there is an added charge varies, so your agent can tell you what a specific request involves before you commit to it in a contract.
