The ACORD 57 Professional Liability Application is used to apply for professional liability insurance — also called errors and omissions (E&O) insurance. Professional liability covers claims arising from negligent acts, errors, or omissions in the rendering of professional services. Unlike general liability, professional liability is claims-made coverage that responds to claims made during the policy period regardless of when the error occurred.
Professional liability is needed by any business or individual who provides professional services or advice: • Consultants and management advisors • Technology companies and IT service providers • Marketing and advertising firms • Accountants and bookkeepers (if not covered under a separate CPA form) • Real estate agents and brokers • Engineers and architects (often use specialty forms) • Insurance agents and brokers • Event planners • Any professional whose error or omission could cause financial harm to a client
Professional liability is almost always written on a claims-made basis — meaning the policy that responds is the policy in force when the claim is made, not when the error occurred.
The retroactive date (also called the prior acts date) is the date before which claims are not covered. A policy with a retroactive date of January 1, 2020 will cover claims made during the policy period for errors that occurred after January 1, 2020.
When quoting a new professional liability policy, agents should try to secure a retroactive date that goes back to when the business first needed coverage — called "full prior acts" coverage. A gap between the retroactive date and when the insured started operations leaves uncovered exposure for services already performed.
The ACORD 57 requires a detailed description of the professional services the insured provides. Underwriters need to understand:
• What specific services are provided • Who the clients are (industries, size of clients) • Whether the insured has written contracts with clients • What professional qualifications or licenses the insured holds • Whether services include making representations or giving advice that clients rely on financially
A vague description like "consulting services" is not sufficient. The operations description should detail specifically what the insured does, for whom, and how advice or services are delivered.
Professional liability underwriters are highly focused on prior claims and incidents. The ACORD 57 asks about claims, suits, and demand letters received, but also about known incidents — circumstances the insured is aware of that could give rise to a claim.
Under most professional liability policies, if the insured knows of a circumstance at inception that later gives rise to a claim, the claim is not covered. Agents must make sure clients understand the need to disclose any potential claims or circumstances before the policy is bound.
Prior claims significantly affect pricing and availability. Underwriters want to know what happened, the total amount paid, and what the insured did differently to prevent recurrence.
Not explaining the retroactive date and prior acts coverage to clients — they often don't understand what they're buying
Accepting a retroactive date that doesn't go back far enough to cover existing work in progress
Not asking clients about known circumstances before binding — this is an E&O exposure for the agent
Writing a vague operations description that doesn't accurately describe the services
Not offering extended reporting period (tail coverage) when a professional liability policy is cancelled or not renewed
