A named insured is listed in the declarations and holds the policy's full rights and full duties. An additional insured is an outside party granted a narrower slice of insured status by endorsement, with coverage only for liability arising out of the named insured's work or relationship, no limits of its own, and no say in the policy. Everywhere the CGL says "you," it means the named insured, and that single drafting choice drives almost every practical difference between the two statuses.
Brokers field this comparison constantly, usually when a client asks why being "added" to someone's policy is not the same as having one. The clean way to answer is to walk the insured status hierarchy that CG 00 01 builds, because additional insured status only makes sense as the bottom tier of that structure. This guide covers the tiers, the first named insured's special duties, what each status grants and gives up, and how to evidence each one without creating E&O exposure.
Insured Status Tiers
The CGL policy recognizes insureds at three levels: named insureds listed in the declarations, automatic insureds who qualify through their relationship to a named insured under Section II, and additional insureds granted limited status by endorsement. Each tier down carries fewer rights and fewer duties.
What are the three tiers of insured status under CG 00 01?
The CGL builds insured status in three tiers, and every coverage question about a party starts with locating them on that ladder. The top tier is the named insured, each person or organization listed in the declarations, who holds the contract's full rights and owes its full duties.
The middle tier is automatic insureds under Section II, Who Is An Insured. These qualify through their relationship to the named insured, and the entity type drives the list: a sole proprietor's spouse for business conduct, partners in a partnership and their spouses, LLC members and managers, executive officers, directors, and stockholders of a corporation, trustees of a trust, plus employees and volunteer workers acting within their duties and real estate managers acting on the named insured's behalf.
The bottom tier is additional insureds, outside parties written onto the policy by endorsement because a contract demands it. Nobody drifts between tiers. Status comes from the declarations, from Section II, or from an endorsement, and from nowhere else.
Two Section II details trip up practitioners more than the rest. A newly acquired or formed organization qualifies as a named insured automatically, but only until the 90th day or the end of the policy period, whichever comes first, and the provision never picks up partnerships, joint ventures, or LLCs.
And no person or organization is an insured for the conduct of any current or past partnership, joint venture, or LLC not shown as a named insured in the declarations, which is how completed operations coverage quietly dies when an agent renames a partnership's policy to its successor corporation instead of listing both.
What special duties does the first named insured carry?
When a policy lists several named insureds, the one listed first is the carrier's single point of contact, and the policy conditions load specific obligations onto that slot. The first named insured is responsible for the payment of premiums, receives any return premium, is the party the insurer bills for an audit balance under premium audit conditions, is authorized to request changes to the policy on behalf of every insured, and is the party entitled to notice of cancellation or nonrenewal.
Workers compensation policies make the same move under the sole representation condition, where the first named insured on the Information Page acts for all insureds on changes, return premiums, and cancellation notices. The auto form does it through its premium audit condition, which bills the first named insured for any final premium balance.
Order matters. Everyone else in the declarations is along for the ride.
The advisory point for brokers is that the first slot should belong to the entity with the treasury function and staff who actually open carrier mail. A cancellation notice sent to a dormant holding company is still valid notice. Review the first named insured at every renewal, confirm the entity still exists, and confirm it matches whoever pays the bill, because fixing this takes one endorsement before a loss and a coverage fight after one.
What does an additional insured get?
An additional insured gets real coverage, which is what separates the status from a certificate holder's purely informational position. On the CGL the status usually arrives through CG 20 10 for ongoing operations, CG 20 37 for completed operations, or a blanket form triggered by written contract. Once endorsed, the additional insured can tender a covered suit to the named insured's carrier and receive a defense paid as supplementary payments outside the limits.
It reaches the named insured's limits before its own respond, especially when the endorsement is paired with primary and noncontributory wording, and its own policy effectively sits excess. It also picks up practical subrogation protection, since carriers generally do not pursue recovery against their own insureds, and it keeps a backstop when a state anti-indemnity statute voids the hold harmless clause the parties actually negotiated. Vendors, landlords, project owners, and general contractors request the status for exactly these reasons, and some will not sign without it.
The full family of forms, edition date differences, and contract wording traps are covered in our guide to additional insured endorsements, so this page stays on the status comparison itself.
What does additional insured status give up?
Everything the endorsement grants, it caps, and the caps are the difference between the tiers. Coverage applies only to liability caused, in whole or in part, by the named insured's acts, omissions, or work, so the additional insured's sole negligence is not covered under post-2004 ISO editions.
The additional insured brings no limits of its own to the policy. All insureds share the named insured's per occurrence and aggregate limits with no priority for anyone, so a large loss can leave the named insured holding an exhausted policy. Current ISO editions also pay no broader coverage than the contract requires and no more than the limits the contract demands, whichever is less.
The additional insured has no authority to change the policy, no right to return premium, and no entitlement to cancellation notice unless a separate notice endorsement adds one. Its protection dies with the policy term or the endorsement, whichever ends first.
The separation of insureds condition cuts both ways here. It preserves coverage for a compliant insured when another insured breaches a condition, but it also obligates the carrier to treat each insured individually, which is how one insurer ends up funding two defense strategies that point at each other.
How do the two statuses compare side by side?
The tier framework collapses into a working comparison brokers can put in front of a client:
| Named insured | Additional insured | |
|---|---|---|
| How status is created | Listed in the declarations | Endorsement, scheduled or blanket, usually triggered by written contract |
| Scope of coverage | Full policy scope for its own operations | Only liability arising from the named insured's work or relationship, never its own sole negligence |
| Limits | Shares policy limits, controls their size at purchase | Shares the same limits, adds none, and current editions pay the lesser of contract or limits |
| Premium and audit | First named insured pays premium and audit balances | No premium duty, though the named insured may be charged for scheduled endorsements |
| Policy changes | First named insured may request changes for all insureds | No authority over the policy at all |
| Cancellation notice | Sent to the first named insured | None, unless a notice endorsement is purchased |
| Duration | Full policy term, renewable | Ends with the policy, the project wording, or the contract that triggered it |
Read the table down the additional insured column and the pattern is consistent. The status is a passenger seat. It gets you where the contract needs you to go, and it comes with no keys.
How should each status be evidenced?
Named insured status is evidenced by the declarations page, and nothing less should satisfy a broker confirming it. Additional insured status is evidenced by the endorsement itself or the policy's blanket wording, with the certificate serving only as a pointer to that paper.
When your agency issues certificates, show additional insured status only when a matching endorsement exists on the policy, and reference the form number and edition date in the description of operations. A certificate that claims status the policy does not grant protects nobody and manufactures E&O exposure for the issuing agency, because the certificate holder relied on your representation.
On the incoming side, when your client is the one requiring the status, collect the endorsement copy at contract signing and again at each renewal, and check that the scheduled entity name matches your client's legal name exactly. Adjusters read schedules literally. An endorsement naming the management company does not clearly cover the ownership LLC standing next to it.
Frequently asked questions
What is the difference between a named insured and an additional insured?
A named insured is listed in the policy declarations and holds the contract's full rights and duties, including premium obligations and coverage for its own operations. An additional insured is an outside party added by endorsement with coverage limited to liability arising from the named insured's work or relationship, sharing the named insured's limits and holding no authority over the policy.
Can a policy have more than one named insured?
Yes. Multiple entities can be listed, and nothing in the Commercial Lines Manual requires common ownership, though individual carriers apply their own underwriting rules. The entity listed first becomes the first named insured and takes on the premium, notice, and policy change duties for the whole group.
Does an additional insured get its own limits?
No. All insureds share the named insured's per occurrence and aggregate limits, and no edition of the standard additional insured endorsements increases them. Current ISO editions also cap recovery at the lesser of what the contract requires and the limits actually available.
Should a client be a named insured or an additional insured on a related entity's policy?
Commit to named insured status when the entity has its own operations or shares ownership, because it needs full scope coverage and its own duties. Additional insured status fits arm's length contractual relationships where the party only needs protection from the named insured's work. Adding a true operating entity as a mere additional insured leaves its independent operations bare.
