The ACORD 57 Professional Liability Application collects the information underwriters need to quote errors and omissions (E&O) coverage. The most important parts are the exact professional services provided, client and revenue details, prior acts date, and any known claims or circumstances. Unlike general liability, professional liability is usually claims-made coverage.

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
Before completing ACORD 57, collect the named insured and entity details, a precise description of every professional service, annual revenue by service, client industries and geographic reach, qualifications and licenses, written contract practices, and the requested limits and deductible. Confirm the current and expiring carrier, retroactive or prior acts date, and full claims, suits, demand letters, and known circumstances history. Have the insured explain corrective action for any prior incident rather than answering only yes or no.
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
Send your client a plain-English intake link. When they finish, the completed ACORD 57 and all required companion forms are generated and ready to submit.
