Certificates Are Proof, Not Protection
Certificates of insurance get exchanged constantly in construction. Understanding what they show and what they don't helps you verify coverage and meet requirements.
What a Certificate Is
A certificate provides evidence that insurance coverage exists at the time of issuance. It summarizes key policy information including carrier, policy number, limits, and effective dates.
What it isn't: actual insurance. A certificate doesn't create coverage. It doesn't guarantee future coverage. It doesn't replace reading actual policy documents.
Key Certificate Sections
Named Insured
The entity holding the policy. Verify this matches the party you're contracting with. Corporate names must be exact. If you're hiring ABC Plumbing LLC, a certificate for ABC Plumbing Inc. may not provide the protection you expect.
Insurance Companies
Carriers providing each coverage type. Check that they're licensed in California. Research their financial ratings if you're uncertain.
Policy Numbers and Dates
Each policy shows a number and effective dates. Verify dates cover your project period. Expired policies obviously don't help you.
Coverage Limits
Limits for each coverage type are listed. Compare to your contract requirements. Don't accept inadequate limits.
Certificate Holder
Your company, listed to receive the certificate and typically to receive notice of policy changes or cancellation.
What to Verify
| Checkpoint | Why It Matters | |-------|---------------| | Named insured matches contract | Ensure correct entity is covered | | Policy dates are current | Expired coverage is worthless | | Limits meet requirements | Don't accept less than you specified | | Endorsements are listed | Verbal assurances aren't enforceable | | You're properly listed as holder | Ensures you receive cancellation notices |
Red Flags on Certificates
Unknown Carriers
If you don't recognize the insurer, verify they're licensed and financially sound. Fly-by-night carriers may not pay claims.
Claims-Made Policies
Most contractor GL is occurrence-based. Claims-made policies on a certificate warrant questions about retroactive dates and what happens if the policy isn't renewed.
Aggregate Limits Already Reduced
If prior claims have eaten into aggregate limits, less coverage may be available for your project.
Missing Workers' Comp
A sub with employees who has no workers' comp is violating California law. Don't let them on your site.
Requesting Your Own Certificates
When you need certificates, provide exact certificate holder name and address, required additional insured language, project information if specific, and list of required endorsements.
Standard turnaround is one to two business days. Rush processing is available for urgent needs. Complex requests with unusual requirements take longer.
Certificate Limitations
Certificates can be issued in error. They can reflect policies that have since been cancelled. They may inaccurately describe endorsements.
For high-stakes situations, verify directly with the carrier. Call using contact information from the carrier's website, not from the certificate itself.
Common Questions
How long is a certificate valid?
Until the underlying policy expires or changes. There's no separate certificate expiration.
Can I rely on a certificate alone?
For routine verification, yes. For significant exposures or unusual situations, verify directly with the carrier.
What if a certificate contains errors?
Request immediate correction. Errors may indicate larger coverage problems.
