What is insurance that cannot be procured through admitted insurers called?

The term for insurance that cannot be obtained through admitted insurers is known as surplus lines insurance. This type of insurance is placed with non-admitted insurers, meaning these carriers do not have a license to operate in the state's insurance market but can offer coverage that is often more specialized or higher-risk than what licensed, admitted insurers are willing to underwrite.

Surplus lines insurers provide coverage for risks that are typically more difficult to insure, such as unique or niche industries and high-risk businesses that do not fit standard underwriting criteria. Because they operate outside of the state's insurance regulations, surplus lines must be handled by brokers who are specifically licensed to place such coverage.

In contrast, excess insurance refers to policies that provide additional coverage beyond what primary insurance does, while reinsurance involves an insurer transferring some of its risk to another insurer to reduce exposure. "Ground insurance" is not a recognized term in the context of insurance types and does not pertain to the scenario presented. These distinctions underscore the uniqueness of surplus lines in the overall insurance landscape.
