Summary

A certificate of liability insurance (often called a COI) is a document that proves your business has liability coverage, such as general liability insurance. It’s commonly requested by landlords, clients, and business partners because it shows your policy details, coverage limits, and who is insured. To get one, you’ll need an active business insurance policy first—then you can usually download your COI from an online account or request it from your insurer or agent.

🧾 What a Certificate of Liability Insurance Is

A certificate of liability insurance is a proof-of-coverage document for your business. It’s not the same thing as the policy itself—it’s a summary form that reassures clients, partners, and others that your company is insured against certain claims, such as bodily injury, property damage, or other covered harms. In most cases, a COI is tied to a general liability insurance policy, but it can also list other types of liability coverage your business carries.

Takeaways:

• A COI is a quick way to show others that your business has active liability insurance coverage.

• It’s often requested before work begins, especially for contractors and service-based businesses.

• A COI summarizes coverage but does not replace the full insurance policy.

Key Terms

• Certificate of Insurance (COI): A document that summarizes your business insurance coverage and proves the policy is active.

• General Liability Insurance: Coverage that can protect your business from claims such as third-party injuries or property damage.

• Insured Party: The person or business covered by the insurance policy.

📄 What Information a COI Typically Includes

A certificate of liability insurance is designed to be easy to read and confirm coverage at a glance. It commonly lists your insurance company’s name, policy numbers, the policy’s effective dates, and your coverage limits. It also identifies the insured parties, and may include additional insureds when required by a contract. If your business carries other liability-related coverage—such as commercial auto, workers’ compensation, or excess liability—those policies may appear on the certificate as well.

Takeaways:

• Most COIs include insurer details, policy numbers, effective dates, and coverage limits.

• The certificate may list multiple policies, not just general liability.

• Names matter—double-check that the insured business and any additional insureds are listed correctly.

Key Terms

• Policy Effective Dates: The start and end dates showing when the coverage is active.

• Policy Limits: The maximum amounts an insurer may pay for covered claims.

• Additional Insured: A person or organization added to your policy who receives certain protections under your coverage.

🏢 When You Might Need to Show a COI

Some businesses need to provide certificates of liability insurance regularly, especially contractors and service businesses that work at client locations. A landlord may request a COI to confirm your general liability coverage protects against potential property damage. A business partner might want proof of workers’ compensation insurance before signing a contract. You can also request COIs from vendors you plan to work with to confirm they carry their own coverage.

Takeaways:

• COIs are commonly required for contracts, leases, and vendor relationships.

• Landlords, clients, and partners may ask for proof before allowing work to start.

• You can request COIs from vendors to verify their insurance too.

Key Terms

• Workers’ Compensation Insurance: Coverage that can help pay for employee medical bills and lost wages after work-related injuries.

• Commercial Auto Insurance: Coverage for vehicles used for business purposes.

• Vendor: A third party (supplier or service provider) your business hires or works with.

💲 Cost and Timing: What to Expect

Certificates of liability insurance are generally free for existing policyholders. The bigger cost is the insurance policy itself, which can vary depending on your industry, the size of your business, how many employees you have, and your claims history. As for timing, you may already have a COI in your insurance paperwork once your policy is active. Many insurers offer instant digital certificates, while others may require a request and typically provide the COI within hours.

Takeaways:

• COIs are usually free once you have an active policy.

• Insurance premiums vary widely, so comparing quotes can help you find a better fit.

• Many providers offer instant COIs, while others deliver them within a few hours after a request.

Key Terms

• Premium: The amount you pay for an insurance policy (monthly or annually).

• Claims History: Your record of past insurance claims, which can affect pricing.

• Quote: A price estimate for coverage based on your business details and risk factors.
