How Insureds and Additional Insureds Can Impact Your Insurance

APRIL 7, 2026

On a business’s general liability policy, there are two major categories of insureds, and it’s important to understand the distinctions between them — particularly when your company is contractually agreeing to extend insured status to someone else.

• Named insureds are individuals or entities to whom the insurance policy is issued. They typically have more rights and responsibilities than other insureds and additional insureds.
• Additional insureds are third parties that request or require insured status due to contractual requirements or a desire to shift liability to another party. The additional insured can submit claims against the named insured’s insurance carrier, rather than submitting them under their own policy.

A lot of businesses provide or request additional insured status without understanding the resulting risk transfer or risk acceptance. Common categories of additional insureds looking for protection can include:

• Lessors
• Vendors
• Project owners
• Business partnerships

Additional insureds can be added to policies via endorsements, of which there are many available forms. Each endorsement provides different levels of indemnification.

How Does Having Additional Insureds on Your Policy Affect Your Coverage?  

If an additional insured is pulled into a lawsuit as the result of the named insured’s negligence, the additional insured status provides the right to defense coverage. Defense costs can dilute policy limits for the named insured.

The number of available additional insured endorsements and differences in how they extend coverage mean that without careful attention to detail, agents may not select the most appropriate endorsements to achieve a client’s goals — leaving the client exposed to unexpected claims, quickly diminished limits, and increased premiums.

Additional insured status is not a substitute for a well-designed contract. Regardless of the direction of risk transfer, consideration must be given not only to the lines of coverage and limits required, but also to indemnity provisions, waivers of subrogation, liability limitation clauses, and how additional insured status is requested. A single point of failure in the contractual risk transfer process can have major financial implications for the insured.

Industrial Case Study

USI Insurance Services recently worked with a manufacturer whose vendors were required to be listed as additional insureds for product liability. After reviewing the manufacturer’s contracts and policy, we discovered that they were listing their vendors under the incorrect additional insured endorsement.

In the event of a claim, coverage could be denied — leaving the manufacturer out of compliance with their own contract as well as financially liable for defense costs and any adverse judgment.

Once they became our client, we made sure they had the correct additional insured endorsement, which brought the manufacturer into compliance with their contract and eliminated a gap in coverage up to the policy limit of $2 million.

Contractor Case Study

A subcontractor was concerned with the risks associated with contractual compliance that required them to provide coverage for both the general contractors and project owners.

USI reviewed their current policies and contracts, and saw that their policies didn’t properly address the additional insured requirement, leaving them exposed to an uninsured loss. We were then able to add the appropriate additional insured endorsement, eliminating exposures to uncovered losses and legal fees up to the policy limit of $1 million.
