A Certificate of Insurance (COI) is a document issued by an insurance company or an insurance broker that acts as a proof of an insurance policy and outlines the conditions of the policy. It contains details of the policy holder, the type of coverage, the policy effect date and other key information about the policy.
In commercial real estate, owners, tenants and real estate agents are to have an insurance policy to protect in the event of an accident or property damage. Real estate management companies require their tenants and vendors to enlist the company as an additional insured to protect them from risk and liability as a consequence of the actions of the policy holder.
