Professional Liability: Errors and Omissions

Professional liability — malpractice in medicine and law, errors and omissions (E&O) everywhere else — pays when a client claims your professional service cost them money: negligent advice, a missed filing deadline, a defective deliverable, a promised task never done. The plaintiff is your own client, and nothing else in your stack responds. General liability covers bodily injury and property damage, and a client whose systems migration failed has suffered neither.

Most of what you are buying is defense. A client who blames you for a failed launch or a bad tax position will usually lose, and will usually cost you six figures of legal fees finding that out. That is why a one-person shop with a thin balance sheet still needs the policy: the lawsuit arrives whether or not the claim has merit, and the carrier’s duty to defend is the benefit you will actually use.

Who needs it. Anyone whose deliverable a client relies on for money: consultants, software and IT contractors, designers and agencies, fractional executives, financial planners and investment advisers, recruiters, real-estate agents, engineers, architects, lawyers, and accountants. Where no statute forces the purchase, a contract usually does. On the licensing side, fifteen states make E&O a condition of an active real-estate license: Alaska, Colorado, Idaho, Iowa, Kentucky, Louisiana, Mississippi, Montana, Nebraska, New Mexico, North Dakota, Rhode Island, South Dakota, Tennessee, and Wyoming. All but Rhode Island run a state-contracted group policy, and $100,000 per claim is the usual floor. Colorado’s statute exempts only inactive brokers and attorneys already carrying malpractice cover (C.R.S. §12-10-204). Oregon (through the bar’s mandatory Professional Liability Fund) and Idaho (since 2018) require malpractice cover of lawyers in private practice. California stops short of a mandate but makes an uninsured lawyer say so to the client in writing at engagement (Rule of Professional Conduct 1.4.2). On the contract side, an enterprise client’s master services agreement typically asks for $1M per claim and $2M aggregate of E&O, plus general liability and cyber, evidenced by a certificate before the first purchase order. No policy, no contract.

The terms that decide whether it pays. Two E&O policies with the same limit and premium can behave nothing alike on the day a claim arrives. Read for these:

Claims-made trigger

Nearly all E&O is written claims-made: it covers claims first made against you during the policy period — and, on the common claims-made and reported form, reported to the carrier within it — for work performed after the retroactive date. The date of the lawsuit decides coverage, not the date of the mistake, so coverage has to stay continuous for as long as old work can produce a claim. That is longer than the practice lasts.

Retroactive date

The earliest date of work the policy covers. Treat it as permanent. When you change carriers, buy prior-acts coverage back to your original retroactive date; a new policy with a fresh date leaves every earlier engagement uninsured, and nobody selling you the cheaper renewal will mention it.

Extended reporting period

Close the practice, retire, or take a W-2 job, and claims for past work keep coming, because the limitation period for professional negligence often runs from discovery. California gives a legal-malpractice plaintiff one year from discovery, up to four years from the wrongful act (Code Civ. Proc. §340.6). The extended reporting period — the tail — keeps the reporting window open for a one-time premium: roughly 75%–150% of the final annual premium for one extra year, about 300% for an unlimited tail, and around 200% in medical malpractice. On the $1,050 median premium, an unlimited tail is about $3,150, paid once. Price it before you give notice. Most professional forms waive the charge on death or disability, and on retirement after a minimum age and tenure (age 55 with five continuous years is a common condition); that provision is worth choosing a carrier for.

Defense within limits

On most E&O forms, legal fees come out of the limit. A $1M policy that spends $350,000 defending leaves $650,000 for the judgment. Size the limit for that erosion, or buy defense outside the limit where the market offers it; the umbrella’s habit of paying defense on top (section “Umbrella Insurance”) does not carry over.

Consent to settle

The carrier cannot settle without your consent, but a hammer clause caps what it pays once you refuse a settlement it recommends. Under a full hammer, every dollar of defense and indemnity above the recommended figure is yours; a soft hammer splits that excess, most commonly 50/50, sometimes 70/30 with the carrier carrying the larger share. If your license and reputation matter more to you than the check — and for a professional they should — pay for the soft hammer.

Contractual liability

E&O covers the liability the law imposes on you, not the liability you volunteer for. An uncapped indemnity, a guarantee of results, a liquidated-damages clause — none of it is insured beyond what you would have owed without the contract. Read the client’s paper against your policy before you sign it.

Regulatory defense

For a licensed professional, a board complaint is more likely than a lawsuit, and it costs real legal fees even when dismissed. Look for a disciplinary-proceedings sublimit and treat its absence as a defect.

Exclusions

Fraud and intentional acts (typically defended until a final adjudication, then excluded), bodily injury and property damage (the general-liability policy’s job), fee disputes and return of fees, intellectual-property infringement outside a technology or media form, and claims between entities you own.

Report circumstances before you renew. The most valuable clause in a claims-made policy is the one almost nobody uses. When you learn of something that could turn into a claim — a client email that mentions its lawyers, a deliverable that failed in production, a deadline you missed — report it to your current carrier as a notice of circumstances. Any claim that later grows out of it attaches to the current policy, even if it arrives years after that policy expires. Stay silent and switch carriers instead, and you are uninsured for it. The new application asks whether you know of any circumstance that could give rise to a claim: the honest answer gets it excluded, and the dishonest one gets the policy rescinded when the claim arrives. Report first, then shop.

Why the tail costs what it does. A first-year claims-made policy covers one year of past work, so it is priced at a fraction of the mature rate — a typical schedule runs 35%, 65%, 85%, and 95% of it in years one through four — and reaches maturity in about five years, sometimes seven or eight. The tail is the bill for those cheap early years, presented when you leave. The alternative is an occurrence policy, which covers any incident during the policy year no matter when the claim is filed and never needs a tail. General liability is written this way as a matter of course; in professional lines the occurrence form survives mainly in parts of the medical-malpractice market, and it costs more every year. If you expect to change states, employers, or careers, compare lifetime cost — occurrence premiums against step-rated claims-made premiums plus the tail — instead of the first-year quote.

The cheapest E&O is a sentence in the contract. Negotiate the client’s paper before you insure against it. Cap your total liability at the fees paid under the engagement, or over the prior twelve months; exclude consequential damages and lost profits; limit your indemnity to third-party claims for bodily injury, property damage, and intellectual-property infringement; and strike any promise to name the client as an additional insured on the E&O policy, which most professional forms cannot do at all (the request belongs on the general-liability policy). Large clients push back, and the cap usually survives at some multiple of fees. Then set the policy limit at or above the cap plus a defense budget, so that the contract and the policy describe the same risk.

Sizing. $1M per claim with a $1M–$2M aggregate is the working default for a solo practice and the figure most contracts ask for. Go higher when one engagement could cost a client well beyond that — a systems integrator on a bank’s core platform, an engineer stamping structural drawings — and buy the extra as an excess professional layer: no umbrella, personal or commercial, extends over E&O.

If you also have a day job. The employer’s policy covers you as an employee doing the employer’s work. It does not follow you to a side consultancy, an expert-witness engagement, or a startup advisory role. Buy your own policy for the side practice once the income is real. For an advisory role, the question is whether the company’s D&O policy covers you. The major private-company forms do include advisory-board members — Chubb’s and Travelers’ in the base definition of an insured person, others by endorsement — but only a duly elected or appointed member of a formally constituted advisory board. An informal advisor working under a consulting letter is usually outside it. Ask for a board resolution naming you to the advisory board and a written indemnification agreement. If the company will do neither and your advice carries real weight in its decisions, decline the seat.
