PROFESSIONAL LIABILITY INSURANCE coverage, or also known as, Errors & Omissions (E&O) coverage insures you against damages or injury arising out of your negligent acts, mistakes, errors and omissions in rendering or failure to take appropriate action in the performance of your professional services as defined in the policy. Please note that there is no standard wording used in E&O policies, so the description of services covered and scope of coverage should be reviewed carefully for your business to ensure proper level of coverage.
