$2M Professional Liability (E&O) Insurance for Expert Witnesses

Expert witnesses asked to carry $2M in Professional Liability (E&O) need a policy that pays up to $2M for one claim, usually one primary policy or a primary plus follow-form excess.

What does a $2M requirement mean for expert witnesses?

Professional Liability (E&O, short for Errors and Omissions) covers claims that a mistake in your professional work cost someone money. For expert witnesses, claims usually come from the party that hired you. A $2M clause in an engagement agreement might read like this:

• Each claim: the most the policy pays for one claim. Here, $2M.
• Aggregate: the most the policy pays for all claims in one policy year. Here, also $2M.
• Claims-made: Professional Liability is almost always claims-made. It pays for claims made and reported while the policy is active. The work must also fall on or after the retroactive date (the earliest work date the policy covers).
• After the matter ends: cases can run for years. You may need to keep coverage with the same retroactive date, or buy a tail (more time to report claims about past work). Check what your agreement requires.

Who asks expert witnesses for $2M?

Requests to expert witnesses can be for $1M or less. A $2M request often comes from:

• Large law firms retaining damages, engineering or industry experts on high-value commercial cases.
• Corporate legal departments that apply the same vendor limits to every outside consultant.
• Government agencies retaining experts for enforcement actions or public contract disputes.
• Insurers hiring experts on large property or construction disputes.

If the request is smaller, see $1M for expert witnesses. If it is larger, see $3M for expert witnesses.

How is $2M built?

At $2M, the limit is usually one primary policy (the policy that pays first) written at $2M/$2M. Sometimes a $1M primary plus a $1M excess layer (a second policy that pays after the first is used up) reaches $2M.

Excess should follow form, meaning it uses the primary's terms. If you go this route, confirm with the client that primary plus follow-form excess meets the clause. A commercial umbrella almost never covers Professional Liability, so it usually cannot help.

Expert witnesses often buy Miscellaneous Professional Liability, a general form for service businesses that do not have a form of their own.

If you are an engineer, doctor or accountant, check whether your own professional policy covers expert witness work. Attorneys who testify should check whether their lawyers professional liability policy covers it, since Miscellaneous forms often exclude lawyers' services.

If you carry $1M today, request new quotes for a $2M policy through Morrow, keeping your retroactive date where the market allows.

What will underwriters ask for?

An underwriter is the person at the insurer who decides whether to offer coverage and on what terms. For expert witness work at $2M, they often ask for:

• Your field (for example, damages, engineering or medical) and any license you hold.
• How many matters you take each year, and the typical amount in dispute.
• Your split between consulting, written reports and testimony, and between plaintiff and defense work.
• Whether your testimony has ever been excluded or limited by a court, and why.
• How you run conflict checks, use written engagement agreements and handle confidential case files.
• Prior claims or fee disputes, and your current policy with its retroactive date.

What affects the cost?

• Field and case size. Large commercial cases usually cost more to cover than smaller matters.
• History. Excluded testimony, prior claims or fee disputes can raise the price or narrow options.
• How the $2M is built. One $2M/$2M policy usually costs more than $1M/$2M, and a primary plus excess is priced differently again.
• Retention and defense terms. A higher retention (the amount you pay on each claim before the policy pays, similar to a deductible) usually lowers the premium. See cost factors.

Frequently asked questions

What kind of claim could reach $2M for an expert witness?

A claim over a mistake in your report or testimony could reach $2M. Here are hypothetical examples. A damages expert's spreadsheet double counts lost profits, the error comes out at deposition, and the client says it lost the case because of it. Or an expert misses a report deadline and the court bars the testimony.

Doesn't witness immunity protect me?

Not always, because immunity rules vary by state and by situation, and this article cannot tell you whether they apply to you. A lawyer can answer that. Even a claim that fails can cost a lot to defend, which is one reason clients ask for this coverage.

I have a $1M/$2M policy. Does that meet a $2M requirement?

Only if the clause asks for $1M per claim and $2M aggregate. If it asks for $2M per claim, you need a higher per-claim limit. Report anything that could become a claim to your current carrier before switching.
