What is Architects and Engineers Errors and Omissions and Professional Liability?
Architects and Engineers Errors and Omissions (E&O) and Professional Liability Insurance is designed to protect professionals and their firms against claims arising from alleged mistakes or negligence in the course of their work. This coverage is essential for architects, engineers, and design professionals who provide specialized services where errors could lead to financial losses, property damage, or other liabilities for their clients.
The policy is typically written on a claims-made basis, meaning it covers claims made during the policy period, provided the incident occurred after the retroactive date. High deductibles are common due to the potential severity of claims in this field.

Only if the policy includes prior acts coverage and the work occurred after the retroactive date listed in your policy.
