Property managers transfer risk to vendors and tenants by requiring them to carry insurance and name the owner as additional insured. The certificate of insurance is how that requirement gets documented, and treating the certificate as proof is exactly where the risk transfer quietly fails. A certificate summarizes a policy; it does not guarantee the coverage is in force or that the protection you required actually exists.
What a certificate does and doesn’t do
A certificate of insurance is a snapshot of a policy’s coverages and limits as of its issue date. It proves a policy existed at that moment, but it grants no rights, can be out of date the next day, and can claim additional-insured status the underlying policy never granted. The endorsement is the document that actually amends a policy. The certificate points at coverage; the endorsement is the coverage.
Where it goes wrong
The common failure is a drawer full of certificates, collected once and never verified or updated. A vendor’s policy lapses, an additional-insured endorsement was never issued, a limit was lower than the contract required, and none of it surfaces until a loss needs the coverage the certificate implied. The paperwork looked complete; the protection was not there.
How to verify and track
Treat COI management as a process, not a collection. Require the specific coverages, limits, additional-insured status, and waivers your contracts call for; verify those against the actual endorsements rather than the certificate face; track expiration dates; and re-collect before policies lapse. For a portfolio of vendors and tenants, that cadence is what keeps the risk transfer real.
Make the contract carry the weight
Your management agreements and vendor contracts should specify exactly what is required and name the endorsement as the evidence, not just a certificate. Pair that with property management coverage of your own, since the risk you cannot transfer stays with you. A coverage review checks both your COI process and the coverage behind it.
