Certificates of insurance: handling COI requests

What a certificate is, and what it is not

A certificate of insurance, usually on the standard ACORD 25 liability form, is a one-page summary your agent issues to show which policies you carry, the insurers, policy numbers, dates and limits. It is evidence for the person holding it. It does not add coverage, extend dates or change terms. If a client needs to be covered under your policy, the policy itself needs an additional insured endorsement, and the certificate simply reports that the endorsement exists.

That distinction is the reason careful clients ask for the endorsement pages as well as the certificate. It is also why you should never edit a certificate yourself, even to fix a typo. Altering a certificate can be treated as misrepresentation, and the client's lawyer will spot it after a claim. Ask the agent to reissue it.

Handling a client's request step by step

1. 01

   Get the requirements in writing

   Ask for the insurance clause from the contract or the vendor packet. You need required limits, the exact certificate holder name and address, additional insured wording and any waiver of subrogation or primary and non-contributory language.

2. 02

   Compare with your current policy

   Check each requirement against your declarations pages and endorsements. If a limit is higher than you carry or an endorsement is missing, you will need a policy change before the certificate can show it.

3. 03

   Send exact details to your agent

   Forward the clause and the holder details in one email. Copy the names exactly, including the LLC or management company spelling, because a mismatch is the most common reason a certificate gets rejected.

4. 04

   Check the draft before it goes out

   Confirm the insured name matches your legal entity, dates are current, limits match the contract and the description box names the property or project if the client asked for it.

5. 05

   Log it and set a renewal reminder

   Record who received the certificate, what it shows and when your policies renew. Reissue certificates to active clients as soon as renewals bind, before they chase you.

Property managers and commercial clients often run vendor portals that reject certificates automatically. Ask for the portal's checklist on the first request and save it with the client record, so future renewals go through the first time.

The endorsements behind the boxes

• Additional insured: makes the client an insured for claims arising from your work. Ask whether it covers ongoing operations, completed operations or both, since many contracts require both.
• Primary and non-contributory: says your policy responds before the client's own policy and will not ask the client's insurer to share the loss.
• Waiver of subrogation: your insurer gives up its right to recover from the client after paying a claim. It is often requested on general liability, auto and workers' compensation.
• Notice of cancellation: some clients want to be told if your policy is cancelled. Standard certificates limit what an agent can promise here, so ask what the insurer actually provides.
• Blanket versus scheduled: blanket endorsements apply to anyone you agree in writing to cover, which saves a policy change for every new contract.

SBA's guide is a useful refresher on what general liability and the other common lines cover in the first place^[3]. The endorsements simply direct that coverage toward the client.

Why certificates get rejected

Vendor compliance teams and portals reject certificates for a short list of reasons. Fixing them before you send saves a week of back and forth and keeps your first invoice on schedule.

• The insured name on the certificate does not match the legal name on your contract or W-9.
• The certificate holder name or address is spelled differently from the client's requirement.
• A limit is lower than the contract requires, often the auto limit or the umbrella.
• The additional insured box is ticked but the endorsement page is missing or only covers ongoing work.
• Workers' compensation is missing because the owner has no employees, with no exemption document attached.
• One of the policies expires within 30 days, so the portal flags it as about to lapse.
• The description box does not name the property, project or management company the client asked for.

Keep a copy of every accepted certificate and the checklist it passed. Next year's renewal for the same client should look the same, with new dates.

Collecting certificates from your subcontractors

The other half of COI management runs in the opposite direction. When you hire a sub for electrical, roofing, drywall or tree work, their insurance should respond to their mistakes and their workers' injuries. If they have none, the injured worker or the damaged homeowner will look to you, and your insurer may charge premium at audit for payroll paid to uninsured subs.

Classification matters too. The IRS looks at the whole relationship and the right to direct and control the worker, grouping the evidence into behavioral control, financial control and the type of relationship. If you treat an employee as an independent contractor without a reasonable basis, you can be held liable for employment taxes for that worker^[1]. A sub with their own business, insurance and certificates is far easier to defend as independent.

The chart shows why uninsured subs can quote low. Benefits, including legally required insurance, were $14.07 of the $46.89 average hourly compensation cost for private employers in June 2026^[2]. A sub who skips workers' compensation and liability coverage is not more efficient; they have moved that cost onto you. The risk is not abstract: construction and extraction occupations recorded 1,032 fatal work injuries in 2024^[4].

Building a simple tracking system

A spreadsheet works for a handful of subs; scheduling or vendor management software helps beyond that. What matters is that nobody gets dispatched to a job while their certificate is expired.

• Request certificates directly from the sub's agent, not as a PDF forwarded by the sub.
• Call the agent on any certificate that looks edited, has mismatched fonts or lists a policy that started yesterday.
• Treat a workers' compensation exemption as a decision to review, not an automatic pass; check how your state and your insurer treat it.
• Make a current certificate a condition of payment in your subcontract agreement.

Example: a handyman company that subs out electrical

Example (fictional): a handyman company in a busy suburb sends licensed electricians on fixture and outlet work it cannot do itself. One sub's general liability lapsed in March, but nobody noticed until July, when a homeowner's insurer sent a claim for a scorched wall cavity. The handyman company's insurer defended the claim and, at the year-end audit, added premium for the sub's uninsured payroll.

In the example, the owner then set three rules: no dispatch without a current certificate on file, certificates requested from agents two weeks before expiry, and payment held until a renewed certificate arrives. The office manager now spends about half an hour a week on the log, and the company has not had an uninsured sub on a job since.

Two short templates

To your agent: 'Please issue a certificate of insurance to the holder below for our work at the address listed. The contract requires additional insured status for ongoing and completed operations, primary and non-contributory wording and a waiver of subrogation on general liability and auto. The insurance clause is attached. Please confirm whether these endorsements are on our policy before issuing.'

To a subcontractor: 'Before your first job with us, please ask your agent to send a certificate showing general liability, auto and workers' compensation, with our company named as additional insured. We need it on file before we can schedule you, and we will ask for a new one each time your policy renews.' For the bonding side of vendor paperwork, see our guide to license and surety bonds.
