Non-admitted insurer

An insurer not licensed in your state that may still write coverage there through a surplus lines broker, outside the state's rate and form filing rules.

Also called: nonadmitted insurer, surplus lines insurer, E&S insurer, non-admitted carrier

A non-admitted insurer is not licensed, or "admitted," in the state where the risk sits. It can lawfully write coverage there only as surplus lines, placed through a licensed surplus lines broker who usually must first document a diligent search of admitted carriers. These insurers are often licensed in their home state or abroad, and they must meet the destination state's eligibility standards, but that state does not approve their rates or policy forms.

Businesses end up here when admitted carriers decline or restrict a risk: coastal property, certain contractors, habitational, hard-to-place liability, unusual exposures. The trade-offs are concrete. Wording is not standardized, so read the form itself. Surplus lines tax and stamping fees are added to the premium, and the amount varies by state. And if the insurer fails, the state guaranty fund generally does not step in. Under the Nonadmitted and Reinsurance Reform Act of 2010, part of the Dodd-Frank Act, the insured's home state alone regulates and taxes the placement.

Non-admitted does not mean unregulated or unsound; many are highly rated. Check the financial strength rating, confirm the broker is licensed, and ask about cancellation terms.
