TL;DR
Field guide
Certificates are the most widely exchanged and least useful insurance documents in the industry. They are produced in volume, filed carefully, and relied on by people who would be startled to learn what they actually establish, which is very little.
That does not make them worthless. It means the review has to be about what the certificate reveals rather than what it asserts, and about what you request alongside it.

Use this when
A landlord, lender or payer has asked you for evidence of insurance, or a staffing agency, contractor or therapy vendor has sent you theirs. Both directions use the same checklist.
01
From a staffing agency, contractor, therapy provider or any vendor whose people work in your building.
Diary the expiration and request the renewal before it lapses. A vendor working in your building on lapsed coverage is your problem in practice regardless of the contract.
A certificate for an affiliate, a predecessor name or a parent is not evidence for the entity performing the work. This is a common and quiet failure.
All of them, by exact legal name. Then ask for the endorsement, because the certificate box confers nothing. For ongoing work you generally want ongoing operations coverage; where the work leaves something behind, you want completed operations too.
For a staffing agency, a therapy provider or anyone delivering care, general liability alone is not enough. Care is professional services and general liability excludes it. This is the single most common gap in vendor certificates in this industry.
Particularly on workers compensation for a staffing agency. Without one, the agency carrier can pay its own injured employee and then pursue you as the third party whose conditions contributed.
A vendor working across many sites with one shared aggregate can have the limit exhausted elsewhere before your claim arrives. The certificate rarely says this outright, so ask.
Ask whether it is covered and at what sublimit. A staffing agency without it leaves the exposure entirely with you.
02
For a landlord, lender, payer or licensure filing.
The lease exhibit or loan covenant states what is required. Meet the exhibit rather than whatever the property manager emailed, because the exhibit is what a default is measured against.
Institutional landlords hold property through chains of entities and restructure them more often than operators expect. An additional insured endorsement naming a dissolved entity protects nobody.
Additional insured, primary and noncontributory, waiver of subrogation. Keep copies with the lease or loan file. This is what makes an annual compliance check possible in an hour.
Many requirements ask for notice the market will not provide in that form. Where that is true, the fix is an agreed amendment, not a certificate that asserts it anyway.
A requirement satisfied on a shared aggregate can leave you technically compliant on the day and functionally uncovered by the third claim.
Common failures
Treating the certificate as the coverage. It is a snapshot of assertions on the day it was issued, subject to a disclaimer saying exactly that, and it can be accurate on Monday and wrong on Tuesday.
Filing certificates and never requesting endorsements. The certificate is what you collect; the endorsement is what responds. An operator with a full certificate file and no endorsements has documentation rather than protection.
Accepting general liability from a vendor who delivers care. Care is professional services and general liability excludes it, so the certificate can be entirely genuine and entirely useless for the claim you will actually have.
Never re-checking after a landlord restructures. Additional insured schedules go stale quietly.
Assuming a certificate proves a waiver of subrogation. It is a contractual provision that has to be endorsed onto the policy, and a waiver agreed in a contract but never endorsed can prejudice the coverage rather than provide it.
Follow-up questions
Because they are cheap, fast and standardized, and because at scale nobody can review full policies for every vendor. That is a reasonable operational compromise as long as it is understood as a screening tool. The moment a certificate is doing real work, for a material vendor or a lease covenant, request the endorsements behind it.
Yes, and it is the most common vendor gap in this industry. Their nurses and aides deliver care, which is professional services, and general liability excludes professional services. Ask specifically for professional liability, for abuse and molestation with the sublimit stated, and for a waiver of subrogation on workers compensation.
At each vendor renewal, diaried rather than remembered, and immediately whenever a landlord or lender entity structure changes. Both lapse quietly and neither announces itself.
Raise it with the landlord and get the exhibit amended. A certificate asserting a notice provision the policy does not contain is worse than an honest amendment, because it creates a documented representation that will not hold.
