What Are the Key Differences Between Liberty Mutual and The Hartford Professional Liability (E&O) Insurance?

Claims-made or occurrence form

The Hartford says many professional-liability policies are claims-made with a retroactive date and extended reporting period, while some use an occurrence basis. Liberty Mutual names a Physicians & Surgeons Professional program but its listing does not establish the trigger for a quote. A professional changing carriers should compare the actual form and reporting terms; do not assume the Liberty Mutual physician program follows The Hartford’s published examples. The issued policy controls both offers. [5] [3]

Published professional audiences

The Hartford lists accountants, consultants, designers, technology professionals and healthcare professionals among its target industries. Liberty Mutual specifically lists a Physicians & Surgeons Professional program marked “PL Only.” Those catalog descriptions help frame an initial eligibility question, but neither guarantees acceptance for a particular practice or service. Tell each provider what professional work is performed and request the form and exclusions relevant to that class. [5] [3]

What Should You Confirm in Liberty Mutual and The Hartford Professional Liability (E&O) Insurance Quotes?

  • Ask The Hartford which trigger applies to your profession and request the quoted retroactive date and reporting extension. [5]
  • Ask Liberty Mutual’s administrator whether your clinical specialty is considered and what trigger appears in its proposed form. [3]

The Hartford says many E&O policies are claims-made while some are occurrence; Liberty Mutual lists a physician PL-only program but does not establish its trigger.
