What Is Professional Liability (E&O) Insurance?

Professional liability insurance (also known as errors and omissions insurance) helps cover legal costs and damages if your business is accused of:


Errors or oversights

Mistakes happen, even to experienced professionals. If a client alleges that an error, omission, or overlooked detail in your work caused them a financial loss, professional liability insurance helps protect your business from the resulting legal and financial fallout.


Misrepresentation

If a client claims that information you provided was misleading, incomplete, or misrepresented something important, professional liability insurance can help cover legal defence costs and damages related to the claim.


Negligence

Even unintentional lapses can lead to costly legal disputes. E&O coverage helps cover defence costs and potential settlements.

Professional liability insurance can help protect your business if a client claims you failed to meet the expected standard of care in your professional services.


Inaccurate advice

When clients rely on your advice to make decisions, inaccurate guidance can sometimes lead to financial loss. Professional liability insurance helps protect your business if a client alleges that advice you gave was incorrect and caused them financial harm.


Failure to deliver promised services

If a client claims your business did not deliver services as agreed in a contract or proposal, professional liability insurance can help cover claims related to unmet expectations, financial loss, or alleged breach of professional duty.

Professional Liability vs. General Liability Insurance
