Certificate of Insurance
A standardized document summarizing an insured's coverage, issued to third parties as evidence that insurance is in force.
What It Is
A Certificate of Insurance (COI) is a standardized summary document that provides evidence of insurance coverage to a third party. It is issued by the insured's broker or agent and contains key policy information including the insurer name, policy number, effective and expiration dates, coverage types, and limits of liability.
The most common certificate form is the ACORD 25, which covers liability lines. ACORD 27 covers property evidence, ACORD 28 covers evidence of commercial property insurance, and ACORD 75 covers automobile liability. Certificates are informational only — they do not confer rights upon the certificate holder or amend, extend, or alter the actual policy coverage.
Despite their informational nature, certificates are the primary compliance document in commercial insurance. Certificate holders — landlords, general contractors, lenders, project owners — rely on COIs to verify that the parties they work with carry adequate insurance as required by contract.
Why It Matters for Brokers
Certificates are the most frequently requested deliverable in commercial brokerage. A mid-size agency may issue thousands of certificates per year. Errors on certificates — wrong limits, missing endorsements, inaccurate coverage descriptions — create compliance failures and E&O exposure. Brokers must ensure that every certificate accurately reflects the underlying policy and that certificates are updated when policies change. Certificate management is a significant operational burden that directly affects client retention and agency profitability.
Real-World Example
A property management company managing 200 commercial units requires annual COIs from every tenant. The PM's broker issues 200 ACORD 25 certificates at each renewal cycle, each with specific requirements for limits ($1M each occurrence, $2M general aggregate), additional insured status, and waiver of subrogation. One tenant's certificate shows a $1M/$2M CGL but the actual policy was reduced to $500,000/$1M by the carrier. The PM discovers the discrepancy during an audit, creating a lease compliance crisis that takes the broker 40 hours to resolve across multiple accounts.
Common Mistakes
- 1Treating certificates as mere paperwork rather than compliance documents that must accurately reflect the underlying policy.
- 2Manually entering limits and coverage information on certificates instead of pulling data directly from verified policy documents.
- 3Not maintaining a system to track certificate expiration dates and automatically request renewals from certificate holders.
How brokerageaudit.com Handles This
COI Manager automates the entire certificate lifecycle — from initial issuance through renewal. It pulls all coverage data directly from policies verified by Policy Checker, preventing manual entry errors. It tracks every certificate holder's specific requirements, monitors expiration dates, and automatically queues renewal certificates. When a policy changes mid-term, COI Manager identifies every affected certificate and flags them for reissuance.
