How to Read an ACORD 25 Certificate of Liability Insurance

The ACORD 25 — formally the Certificate of Liability Insurance — is the standard form used across the United States to evidence a business's liability coverage. Your vendors' brokers issue it, you file it, and in most offices nobody reads past the vendor's name.

That is a mistake, because a certificate can be entirely valid and still show you a vendor who is unfit to work on your property. Here is how to read one properly.

The five fields that matter

1. The insured (top left)

This must be the exact legal entity you contracted with. "Rivera Plumbing LLC" and "J. Rivera Plumbing & Heating Inc." are different companies with different policies. If the name on the certificate does not match the name on your work order, the coverage may not follow the work.

2. Policy effective and expiration dates

The two date columns in the middle of the coverage grid. The expiration date is the field your entire tracking process revolves around. Check that the policy period covers the whole span of the work — a certificate that expires mid-project is a gap you have agreed to in advance.

3. Coverage types and limits

The main grid lists each policy type on its own row. What you need depends on the trade, but a standard baseline for property vendors looks like this:

Note the difference between per occurrence and aggregate. The aggregate is the total the policy will pay across the whole policy year, shared with every other client that vendor serves. A $2M aggregate that has already absorbed a $1.8M claim leaves you very little.

4. Occurrence vs claims-made

Two small checkboxes on the general liability row. Occurrence policies cover incidents that happen during the policy period, whenever the claim is filed. Claims-made policies only cover claims filed while the policy is active — so once the vendor drops the policy, historical work is uncovered. For property vendors, insist on occurrence-based general liability.

5. The description of operations box

The free-text area near the bottom. This is where additional insured status, primary and non-contributory wording, and waivers of subrogation get referenced. Read it, but do not trust it: text here describes endorsements, it does not create them. Ask for the endorsement pages themselves.

Red flags to check every time

• Expiration within 30 days. Not a rejection, but start the renewal chase immediately.
• Missing workers' compensation. Common with sole proprietors. If they are exempt, get the exemption certificate in writing and understand your state's rules on it.
• Your entity is only in the certificate holder box. Notice, not coverage. See the distinction between additional insured and certificate holder before you accept it.
• An insurer with a weak rating. The "INSR LTR" column maps to the carriers listed above. A policy from an unrated or non-admitted carrier is worth less than it appears.
• Limits below your contract requirement. Astonishingly common — the contract says $2M, the certificate says $500K, and nobody compared them.
• Handwritten alterations. A certificate edited after issue is not evidence of anything. Request a reissued form from the broker.

A one-minute review routine

Every time a certificate arrives, in this order:

• Match the insured name to your contracted vendor entity.
• Record the earliest expiration date across all listed policies.
• Compare each limit against your contractual minimum.
• Confirm general liability is occurrence-based.
• Confirm the additional insured endorsement is attached, not merely described.
• File the PDF where you can retrieve it in ten seconds, and set the reminder.

Where this usually breaks

Almost nobody fails at reviewing the certificate. They fail at step six, eleven months later, when the policy expires and the reminder was a calendar entry someone dismissed. The review is a skill; the renewal is a system. You need both, and only one of them can be automated.
