Evidence of Insurance vs Certificate of Insurance Explained

Last updated July 2026.

Evidence of insurance and a certificate of insurance are different documents for different jobs. A certificate of insurance, the ACORD 25, is an informational summary of a vendor's liability coverage that grants the holder no rights and states plainly that it does not amend, extend or alter the policy. Evidence of insurance, the ACORD 27 or ACORD 28, proves property coverage to a party with a direct financial interest in the property, such as a mortgage lender or loss payee, and it carries more standing than a certificate does. In short, liability coverage is shown on a certificate, and property coverage is shown on an evidence form.

The two terms get used as if they mean the same thing, and on a busy compliance desk that confusion costs real time. Someone asks a vendor for evidence of insurance, the vendor sends an ACORD 25, and the lender or landlord who actually needed proof of property coverage rejects it. Below is the plain-language version of what separates the forms, which one you should ask for, and how the difference shows up when you verify a document.

What is the difference between evidence of insurance and a certificate of insurance?

The difference is standing and subject matter. A certificate of insurance is issued to a certificate holder who has an interest in a vendor's liability coverage, and it is expressly informational: the ACORD 25 says it confers no rights on the holder and does not change the policy. Evidence of insurance is issued to a party with a direct interest in the insured property, such as a mortgagee or loss payee, and unlike the certificate it can carry notice provisions and give the recipient a recognized interest in the policy. That is why a bank financing a building asks for evidence, not a certificate.

Is evidence of insurance the same as a certificate of insurance?

No. They look similar because they are both one-page ACORD summaries pulled from the same policy data, but they serve different purposes and different recipients. A certificate summarizes liability coverage for a third party who wants to confirm a vendor is insured. Evidence of insurance documents property coverage for a party that has money tied to the property itself. Asking for the wrong one is the most common reason a compliance document bounces back, so match the form to what the requesting party actually holds an interest in.

ACORD 25 vs ACORD 27 vs ACORD 28

Three ACORD forms cover most of what people mean by proof of insurance. The certificate covers liability. The two evidence forms cover property, with the ACORD 28 being the more detailed of the pair.

What is an ACORD 27?

An ACORD 27 is the Evidence of Property Insurance form. It documents that a property policy is in force and names the party with an interest in the property, such as a lender or loss payee. It is used when someone financing or holding a stake in a specific property needs proof that the property itself is insured, rather than proof that the owner carries liability coverage. It suits personal property policies and simpler commercial situations where the detailed additional-interest fields of the ACORD 28 are not required.

What is an ACORD 28?

An ACORD 28 is the Evidence of Commercial Property Insurance form, the more comprehensive cousin of the ACORD 27. It carries detailed fields for loss payee status, mortgagee clauses, additional insured parties and specific coverage limits, which is exactly the information a commercial mortgage lender needs before closing. Banks financing commercial real estate typically require the ACORD 28 for that reason. If you manage property loans, this is the form you will see most, and the one where the additional-interest detail actually matters. Lenders that underwrite against the collateral scrutinize this document closely, which is why teams that analyze loan and collateral documents treat the property evidence form as a closing gate rather than a formality.

Does a certificate of insurance prove coverage?

A certificate of insurance is evidence that a policy existed on the day the certificate was issued, but it is not the policy and it grants the holder no rights under it. The ACORD 25 states that it is issued as a matter of information only and does not amend, extend or alter the coverage. Coverage can be canceled or reduced the day after the certificate prints, and the holder has no contractual standing to demand notice unless a specific endorsement adds it. That gap is exactly why insurance requirements ask for endorsements such as additional insured and waiver of subrogation, and why ongoing certificate of insurance verification matters more than filing the document once.

Which form do lenders and landlords require?

Lenders financing property almost always require evidence of insurance, usually the ACORD 28 for commercial real estate, because they hold a direct financial interest in the building and want to be named as mortgagee or loss payee. Landlords and clients hiring vendors require a certificate of liability insurance, the ACORD 25, because their concern is whether the vendor can cover a liability claim. A landlord who also owns the building may ask a tenant for both: a certificate for the tenant's liability and evidence of property coverage on tenant improvements. When a contract says proof of insurance without naming a form, confirm whether the requesting party has an interest in liability or in the property, then ask for the matching document.

How to tell them apart when you verify a document

Read the title block at the top of the page first. A certificate says Certificate of Liability Insurance and lists coverage rows for general liability, automobile, umbrella and workers compensation. An evidence form says Evidence of Property Insurance or Evidence of Commercial Property Insurance and centers on the property location, the coverage amount on the building or contents, and the named lender or loss payee. The disclaimer language differs too: the certificate carries the information-only, no-rights statement, and the evidence forms are structured to give an interested party actual standing. If your team collects both types across many vendors and properties, reading and checking them by hand does not scale, which is where AI COI tracking software earns its place by pulling the fields off each document and flagging what is missing.

Track certificates and evidence forms in one place

Whether a vendor sends a certificate of liability insurance or a lender demands evidence of commercial property insurance, the underlying job is the same: read the document, confirm the coverage matches what the contract requires, and catch it before it expires. COISoftware reads any ACORD form in seconds, checks the limits and required endorsements against the rules you set, and chases the renewal before coverage lapses, so proof of coverage is a live status rather than a folder of PDFs. Upload a certificate or an evidence form at the top of the page to see it read automatically, and read the related breakdown of a certificate of insurance versus proof of insurance or the full anatomy of the ACORD 25 form.
