Quick answer

Professional liability insurance is built around allegations that services, advice, or professional work caused a client financial harm. Pricing depends heavily on what you do, who relies on it, and the scale of a possible mistake.

  • Describe your operations accurately
  • Match limits, deductibles and policy forms
  • Confirm requirements with a licensed professional

Professional liability insurance is built around allegations that services, advice, or professional work caused a client financial harm. Pricing depends heavily on what you do, who relies on it, and the scale of a possible mistake.

Important: This guide provides general educational information, not legal, tax, or insurance advice. Requirements and policy terms vary. Consult a licensed professional about your situation.

Why profession and clients matter

An underwriter may review service descriptions, credentials, client industries, contract size, annual revenue, subcontracted work, quality controls, and the financial consequences of an alleged error. Similar revenue does not imply similar risk.

Claims-made mechanics

Many professional liability policies respond on a claims-made basis. Retroactive dates, continuity, reporting requirements, and extended reporting options deserve close attention when switching insurers. A cheaper replacement can be poor value if it changes those protections.

  • Confirm the retroactive date
  • Compare defense-cost treatment
  • Review consent-to-settle language
  • Check territory and jurisdiction
  • Ask how subcontractors are covered

Prepare a consistent submission

Use the same revenue split, client profile, requested limits, deductible, and loss history for every provider. Attach representative contracts and explain peer review or approval procedures. Compare actual forms and endorsements, not summary labels alone.
