What Professional Liability (E&O) Insurance Requirements Apply in New Hampshire?

New Hampshire requires a state-chartered trust company to maintain an E&O liability policy, with the commissioner setting the amount in light of safety, soundness, and client protection. The statute does not publish a single statewide dollar minimum for every trust company.

What Is Professional Liability (E&O) Insurance?

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. Read the national Professional errors and omissions (E&O) guide.

What to Watch for With Professional Liability (E&O) in New Hampshire

Confirm Your Charter and Entity Type
The mandate in RSA 383-C:5-501 applies to a trust company under the Trust Company Act, which the statute defines as a nondepository state bank conducting trust business. It is not a general E&O mandate for every New Hampshire consulting or fiduciary firm. ¹
Use the Amount Set for Your Company
The commissioner determines the appropriate E&O amount based on safety, soundness, and client protection, and any deductible must remain reasonable without jeopardizing safe operation. Ask for the current company-specific coverage amount and deductible before binding or renewing. ¹
Check the Issuer and Report Major Reductions
The incorporated New Hampshire E&O statute permits an in-state licensed insurer or an authorized foreign surplus-lines insurer, with a limited alternative if the policy consents to New Hampshire court jurisdiction. For state banks and credit unions, a 25% or greater decrease in coverage in any 12-month period must be reported; confirm with counsel or the commissioner how that incorporated rule applies to your trust-company charter. ^1,²
