Diligent Search

A diligent search (also called a diligent effort) is the legally required, documented attempt to obtain coverage from admitted insurers before a risk may be placed with a non-admitted carrier in the excess and surplus market. The rule exists because surplus lines is meant to be a market of last resort, not a shortcut around state-regulated carriers. Most states require the producer or surplus lines broker to obtain a set number of declinations — frequently three — from admitted carriers actually writing that class of business, and to record those refusals on an affidavit or diligent-search form filed with the state or the stamping office.

For a small-business buyer, the diligent search is the gatekeeping step that determines whether your surplus-lines placement is even valid. If your risk — say an unusual liability exposure or a heavily loss-burdened account — genuinely cannot be written by admitted carriers, the documented declinations clear the way to bind coverage that would otherwise be unavailable. The requirement protects you as well: it forces the broker to test the admitted market first, where policies carry guaranty fund protection, rather than defaulting you into a non-admitted policy that lacks that backstop and carries a surplus lines tax.

The practical nuance is that many states waive or streamline the diligent-search requirement for risks appearing on an export list (classes officially recognized as unavailable from admitted carriers) or for certain sophisticated "exempt commercial purchasers." Rules on how many declinations count, which carriers qualify, and how long records must be kept vary meaningfully by state, so buyers should expect their broker to explain and document the process. Keep a copy of the completed affidavit — it is your evidence that the surplus-lines placement was compliant, which matters if the policy or the tax filing is ever questioned.
