Key Differences in Professional Liability (E&O) Insurance
General service work and specialist categories
Corgi’s catalog describes Miscellaneous E&O for service-based businesses facing negligence, errors or failure-to-perform claims, separate from its technology, real-estate and lawyer E&O products. MMA’s source names E&O, architects and engineers, and lawyers professional lines. A service firm should compare Corgi’s broad catalog category with the particular MMA professional line proposed for its services and professional duties. 6 9
Quote timing and line selection
Corgi labels Miscellaneous E&O with a 1–14 day turnaround, distinct from its instant-quote Tech & AI product; its catalog also separates Real Estate E&O and Lawyer E&O. MMA’s source identifies those latter professional categories alongside E&O. If timing or a licensed specialty matters, ask Corgi which catalog route fits and ask MMA to identify the proposed line and its expected quote steps. 2 9
