What this means
Additional insured status gives another party certain rights under your liability policy. It is common for general liability but may not apply the same way to E&O or cyber coverage.
Treat additional insured language as something your broker should review before you promise it.
When it shows up
This usually appears in procurement or vendor onboarding, after business terms are close but before the client will approve work.
In practice, the requirement is rarely only about buying insurance. It is also about showing that you understand the client's risk concern, can produce the right evidence, and know which details belong with a broker, IT/security contact, operations owner, or legal reviewer before you sign.
What to look for in the contract
Look for the certificate holder, required policies, required limits, endorsement wording, due date, and where proof should be sent.
Exact policy names or phrases, such as cyber liability, technology E&O, or professional liability.
Per-claim, aggregate, sublimit, deductible, and any contract-specific amount.
Certificate holder, due date, endorsement wording, and delivery instructions.
How to use this guide
Treat this page as preparation for a more precise conversation. Start with the checklist, gather the evidence you already have, and split unanswered items into coverage questions for a broker and readiness questions for IT, security, or operations.
Checklist
- Identify which policy the contract references.
- Check whether endorsement wording is required.
- Confirm whether additional insured applies to ongoing operations, completed operations, or both.
- Avoid assuming E&O can add additional insured status.
Who should help with what
This is mostly a broker and operations handoff. The main risk is promising certificate wording before the carrier confirms it.
Ask a broker to confirm the certificate holder, policy names, limits, endorsement availability, and any special wording before making commitments to the client.
Ask the internal contract owner or operations contact to confirm the client legal name, delivery email, deadline, and exact contract wording.
Common mistake to avoid
The common mistake is promising certificate wording before confirming the carrier can actually provide the endorsement.
Questions for the right specialist
Coverage questions
- Can this policy add the client as additional insured?
- Is a blanket endorsement already included?
- Does this apply to cyber or only general liability?
Readiness questions
- Who has the exact certificate holder name, address, delivery email, and deadline?
- Does the contract require special wording beyond standard proof of coverage?
- Who should approve the certificate before it is sent to the client?
Build your packet
If this requirement is tied to a real client contract, use the CoverReady checklist to turn the wording into a readiness packet: coverage questions for your broker, technical evidence for IT/security, certificate needs, and items to clarify before making commitments to the client.
