What is professional liability insurance?
Professional liability insurance, also called errors and omissions (E&O), covers claims that your professional advice or services were negligent, contained an error, or failed to deliver, along with the legal defense costs. General liability does not respond to these claims. It is typically written on a claims-made basis, so your retroactive date and continuity of coverage matter.
Professional liability, also called errors and omissions (E&O), protects you when a client claims your professional work caused them financial harm. General liability does not respond to these claims, which makes E&O essential for anyone whose advice or services carry responsibility.

What does E&O cover?
What does Professional Liability Insurance cover?
- Claims of negligence in your professional services.
- Alleged errors, omissions, or failure to deliver as promised.
- Legal defense costs, which can be significant even for disputed claims.
- Certain claims tied to missed deadlines or faulty advice.
- What it generally does not fund: redoing the work, refunding a fee, or a fee dispute. Those are treated as business costs.
Who requires E&O in California?
Some California professions and licensing bodies expect E&O as a condition of practice or contract. We can help you understand what your field and clients typically require.
The end of the policy matters as much as the start. Because it is claims-made, a claim reported after the policy ends is generally outside it, even for work done while it was live. Tail coverage, or an extended reporting period, keeps that reporting window open when you retire, close, or move carriers without continuity.
How do California limitation periods shape a claims-made policy?
Professional liability is written on a claims-made basis: the policy that responds is the one in force when the claim is made, provided the work was done after the policy’s retroactive date. How long after the work a claim can arrive is set by California’s limitation periods, and they differ by profession. For attorneys, Code of Civil Procedure section 340.6 allows one year from discovery of the error or four years from the act, whichever is first. Other professions run on the general contract and negligence periods, and some on their own statutes. Two consequences follow. The retroactive date on a new policy should reach back at least as far as the applicable limitation period, or work already done is uninsured when the claim comes. And when a policy ends, the extended reporting period, sometimes called tail coverage, should run at least as long as the limitation period for your profession. A claim made after cancellation is not a claim under the old policy unless the tail catches it. We check both dates against the period that applies to your work before a policy is bound or dropped.
The Code of Civil Procedure provisions cited here are as published by the California Legislative Counsel at the time of writing. The Legislature amends them from time to time, and that office publishes the current text.
Which professions need it?
Consultants, accountants, tech and design firms, real estate professionals, insurance and financial advisors, medical and allied health providers, and many licensed practitioners. Clients and contracts often require it before engagement.
