Certificate of Insurance (COI): What Clients Ask For and Why
Decode a client COI request: named insured, certificate holder, additional insured endorsements, waiver language, limits, project dates, and the policy behind the certificate.
A certificate of insurance summarizes policy information at a point in time. It is not the insurance contract and normally does not create rights that the underlying policy or endorsements do not provide. The certificate holder is the party receiving evidence of coverage. An additional insured is a party granted certain coverage under the policy or endorsement; putting a name in the certificate-holder box does not create that status.
A COI is a snapshot; an endorsement is what can grant status
A certificate of insurance is a snapshot of policy information at a moment in time. It is not the policy and it does not create coverage by itself. The certificate holder is the party receiving evidence; additional-insured status, when available, generally comes from policy language or an endorsement.
Procurement teams may also ask for specific limits, workers' compensation, auto, professional liability, waiver of subrogation, or project wording. Send the client's insurance exhibit to the broker unchanged rather than translating it from memory.
Send the client’s exact insurance requirements to the broker
Clients may request specific general-liability limits, auto coverage, workers' compensation, professional liability, waiver of subrogation, or additional-insured wording. Send the actual requirement to your broker rather than paraphrasing it from memory.
Before sending a COI to procurement
- Send exact contract insurance wording to the broker.
- Check holder name and project dates.
- Confirm endorsements, not just certificate text.
- Never alter the COI yourself.
- Archive the requirement, certificate, and endorsements together.
- Confirm the endorsement or policy change before telling the client the requirement is satisfied.
Ask for the COI before procurement becomes the deadline
Ask for the COI early. If an endorsement or higher limit is required, the insurer or broker may need more time and may charge additional premium.
Check policy dates against the entire project term
Check policy dates against the project. A certificate showing a policy that expires halfway through a one-year engagement may be technically current today but still create a renewal obligation during performance.
Keep the certificate and the actual endorsement together
Timing is the operational risk. Ask for the COI as soon as procurement raises the requirement, then compare effective dates, named insured, policy types, limits, and requested endorsements with the contract. Keep the certificate together with any endorsement that actually grants the requested status.
Never edit a PDF certificate yourself to satisfy a client; that can create a false document without changing the underlying insurance. If the broker says a requested phrase or endorsement is unavailable, return to the client and amend the requirement or purchase appropriate coverage before work begins. A COI should prove the coverage you have, not manufacture coverage you do not.
Never edit a certificate to imitate coverage you do not have
Do not edit a PDF certificate yourself. Certificates are issued by an authorized producer or insurer; altering limits or names can create serious credibility and legal problems.
COI request decoding sheet
- Certificate holder
- Record the legal name and address the client wants shown as certificate holder. Being listed as certificate holder proves receipt of evidence; it does not by itself grant the client the coverage rights of an additional insured.
- Additional insured
- Identify whether the contract requires additional-insured status, on which policy, and for what operations. Ask the broker for the actual endorsement or confirmation rather than assuming text in a certificate description creates coverage.
- Limits and dates
- Match required per-occurrence/aggregate or professional limits, policy numbers, effective/expiration dates, and any claims-made retroactive information the client needs. A current certificate cannot repair inadequate policy limits.
- Other endorsements
- Flag waiver of subrogation, primary/noncontributory wording, project/location wording, auto/workers-comp requirements, or other endorsements separately. Forward the actual contract insurance clause to the broker so shorthand email requests do not omit a requirement.
Certificate wording cannot replace the endorsement
Treat the client’s COI request as a translation task. First compare the request with your actual policy declarations and endorsements. A certificate generally summarizes coverage; it does not by itself create rights that the policy does not provide. ‘Certificate holder’ usually means the party receiving evidence, while ‘additional insured’ can change coverage status and ordinarily depends on policy language or an endorsement. A waiver of subrogation and primary/noncontributory requirement are additional contractual concepts. Send the exact client legal name, address, project description, requested limits, and required wording to the broker or carrier so they can confirm what is available instead of editing a PDF yourself.
Time the request before project access depends on it. Large clients may reject a certificate because the named insured is wrong, a policy expires before the project ends, the limits do not match the contract, or an endorsement was requested but not shown. Keep the certificate and any endorsements in the project folder with the contract. If the broker says the requested wording cannot be provided, go back to the client before signing or starting work and negotiate the insurance clause rather than promising coverage that does not exist. Also calendar renewal if the project spans a policy term. A fresh certificate after renewal may be required even though the underlying relationship did not change. Never treat a COI as a substitute for reading the policy or understanding the indemnity obligations in the client agreement.
Create a COI request template for clients to complete. Ask for certificate-holder details, required limits, additional-insured wording, waiver requirements, project location, contract section, and deadline. Forward the actual contract language to the broker when possible; shorthand such as ‘need a $1M COI’ can miss an endorsement requirement hidden two paragraphs later. If the broker charges for an endorsement, include that cost in project economics rather than discovering it after the contract is signed. Save the issued certificate under the client/project name and verify the policy number and dates before sending. This turns COI handling from a frantic email chain into a repeatable onboarding step. If the client needs evidence for a specific job site or venue, include that context exactly as requested and ask the broker whether operations there change coverage. A generic certificate created for a prior customer should not be recycled as proof for a new contract.
Decode a client COI request line by line
Procurement sequence: receive the client's insurance exhibit on Monday, send it unchanged to the broker, obtain the COI plus requested additional-insured endorsement, compare limits and dates to the exhibit, and only then upload the documents to the vendor portal. This is safer than requesting 'a standard COI.'
COI questions that prevent procurement surprises
Is a certificate of insurance the policy itself?
No. A COI summarizes selected policy information at a point in time; the insurance policy and endorsements control coverage. Treat the certificate as evidence for procurement, not as a contract that can add coverage by itself. When a client requests additional-insured status or special wording, ask the broker for the actual endorsement and compare it with the contract requirement.
Is a certificate holder automatically an additional insured?
No. Those are different roles. A certificate holder receives evidence of insurance, while additional-insured status generally requires the applicable policy language or endorsement. Ask the broker to confirm the endorsement rather than relying on the COI label alone.
What should I send my broker when a client asks for a COI?
Send the exact insurance exhibit or contract clause, client legal name and address, project dates, required limits, and any additional-insured, primary/noncontributory, or waiver-of-subrogation language. That gives the broker a concrete requirement to compare with the policy.
Can I edit a COI myself to satisfy the client?
No. Altering the certificate does not create insurance and can create serious misrepresentation problems. Ask the insurer or authorized broker to issue the correct certificate and endorsements, or tell the client which requirement the policy cannot meet.
