Why this topic matters

Professional Liability can affect whether a business satisfies a contract, handles a claim, or keeps operating after a loss. The policy forms and endorsements should be reviewed before relying on a short quote summary.

This guide focuses on errors, omissions, negligence, and professional service disputes.

  • Find the exact form or endorsement name.
  • Check limits, deductibles, exclusions, and conditions.
  • Compare contract wording with policy wording.
  • Keep records that would support a future claim or audit.

Questions to ask before buying

Use the same questions with each insurer or licensed professional so answers are easier to compare.

  • Is this included in the base policy or added by endorsement?
  • Does the policy fit the business operations described in the application?
  • What documents are needed for a certificate, audit, or claim?
  • Are subcontractors, vehicles, property, or professional services handled separately?

Documents to keep

A useful insurance file includes applications, quotes, policy forms, endorsements, certificates, contracts, leases, vehicle lists, payroll records, revenue estimates, loss runs, and claim correspondence.

  • Current declarations pages and endorsements.
  • Contracts and certificate requests.
  • Payroll, revenue, vehicle, and property schedules.
  • Incident reports, photos, receipts, and repair records.
