E&O insurance requirements by industry come from two places: the law and the contract. Few professions are required by state law to carry errors and omissions (E&O) insurance. Far more are asked for it by a carrier, a firm, a broker or a client before work can start. This page goes through seven industries one at a time.

| Financial advisors | Rarely | Yes, often by firms and broker-dealers |
| Architects and engineers | Rules vary by state | Yes, often on larger projects |

Why Knowing Your Industry’s E&O Requirements Matters
1. You can start work on time: a licensing board, carrier, agency or client may ask for proof of E&O before you start or keep working.
2. You match coverage to real risk: a missed disclosure or a piece of bad advice can cost a client money whether or not anyone required insurance.
3. Contracts can set a minimum: a client contract may name a minimum limit, so read the insurance clause first.
4. Defense costs come first: a claim needs a lawyer long before anyone decides who was right, and E&O can pay legal defense costs for a covered claim, up to the policy limit.
Insurance Agents
State rules on E&O for insurance agents differ, so ask your state insurance department what applies to your license. In practice the requirement usually arrives by contract. A carrier, a general agency or a marketing organization may ask for proof of E&O before it contracts with you. The typical claim comes from a client who says you recommended the wrong product, missed a coverage detail or never explained a limitation. Before you buy, check that the limit meets the one written in your carrier or agency contract and that the policy describes the kind of business you write. Life and health agents can start with E&O insurance for life and health agents, and can see the claims life and health agents face most often.
Real Estate Agents
It is easy to assume one nationwide rule covers real estate. None does. E&O is required by law for real estate licensees in only some states, about a dozen. Everywhere else the push tends to come from the brokerage, which may require every agent under its roof to be covered. The typical claim comes after closing: a buyer says a problem with the property was never disclosed, or a mistake in the paperwork cost them money. Ask your broker one question before you buy anything. Does the brokerage policy cover you personally, or do you need your own? Check with your state real estate commission, then read E&O insurance for real estate agents.
Accountants and Bookkeepers
Accountants are rarely required by law to carry E&O. Ohio is an exception worth knowing. Under Ohio Administrative Code 4701-13-03, a public accounting firm that is not organized as a proprietorship or general partnership must carry professional liability insurance and certify it when the firm registers. Elsewhere, the request usually comes from a client or from the firm you work under. A late filing or a wrong figure can cost a client a penalty, and the client may look to you for it. Mistakes in a return or a set of books often come to light well after the work is finished, so check the retroactive date and keep your coverage continuous.
Financial Advisors
Financial advisors are also rarely required by law to carry E&O. Contracts, firms and clients usually drive it. A broker-dealer or advisory firm may make coverage a condition of affiliation, and some clients ask for proof before they sign an agreement. The typical claim follows a loss: a client whose account dropped says the recommendation was unsuitable or the risk was never explained. If your firm provides coverage, ask whether it applies only to business placed through that firm. Work you do outside it may need its own policy. Keep in mind that E&O generally excludes intentional or dishonest acts. See E&O insurance for financial advisors.
Architects and Engineers
Rules for design professionals vary by state, so check with the board that issued your license. Contracts are the more common source. Owners and general contractors on larger projects often ask for proof of professional liability coverage and name a minimum limit in the agreement. A design error can carry a large financial loss, and it may surface long after the work was delivered. That makes the retroactive date and continuous coverage matter more here than in most fields. Read the agreement for how long you must keep coverage after the project ends. If you retire or close the firm, tail coverage, also called an extended reporting period, can extend the time you have to report a claim.
IT Consultants
Most IT work has no licensing board, so a legal requirement to carry E&O is unusual. Contracts fill the gap. Business clients often write an insurance clause into a service agreement and ask for a certificate before a project begins. Some also ask to be added as an additional insured. The claims are about results: a system that fails, a missed deadline, or a change that takes a client offline and costs them sales. General liability does not cover that kind of professional mistake, so a general liability certificate alone may not satisfy the clause. Check that the policy describes the services you actually sell. See E&O insurance for consultants.
Marketing Agencies and Consultants
Marketing work is typically not licensed either, so the requirement, when there is one, sits in a client contract. Larger clients ask most often, though any client can. A typical claim says a campaign went out late, went out with a mistake in it, or did not deliver what the agreement promised, and that the client lost money as a result. Agencies have a second reason to look at E&O. Standard general liability policies typically exclude advertising injury for businesses whose own business is advertising, broadcasting, publishing or media. A claim over a campaign you created for a client is therefore a professional liability question. Read what E&O insurance covers before you rely on either policy.
How to Check Your Own Field
The table sums up E&O insurance requirements by industry in general terms. Your own state and your own contracts decide, so check them in this order:
- Ask your state licensing board, or your state insurance department, whether your profession must carry E&O.
- Read the insurance clause in every client contract and agency agreement before you sign, and note any minimum limit.
- Ask the carrier, agency or firm you work with what proof they want. It is usually a Certificate of Insurance.
- Compare the limit you are asked for with the policy you are buying. InsureDirect E&O carries limits of $1M per claim and $3M aggregate.
Eligibility depends on your profession. Physicians and attorneys need malpractice coverage written for their professions, which is a different policy.
Myths About E&O Requirements
Myth: If no law requires E&O for your profession, you do not need it. A client can claim your advice or work cost them money whether or not a rule told you to buy insurance.
Myth: A licensing board is the only place a requirement can come from. Carriers, agencies, firms and clients can ask for E&O too, so read every agreement before you sign.
Myth: Only big clients ask for proof of E&O. Any client can name a minimum limit in an insurance clause, so read it every time.
Frequently Asked Questions
Is E&O insurance legally required for every profession?
No. Few professions are required by state law to carry it, and the rules differ from state to state. Requirements come far more often from carriers, firms, brokerages and client contracts. Check with your state licensing board to be sure.
Which states require E&O insurance for real estate agents?
Only some states require it by law, about a dozen. The list and the minimum limits are set by each state and can change, so confirm with your state real estate commission. Many brokerages require coverage even where the state does not.
What if my industry does not require E&O insurance?
A missing requirement does not remove the risk. A client can still claim that your advice or work cost them money, and even a weak claim needs a lawyer. Judge the need by your client relationships and contracts, not only by formal mandates.
What does an insurance clause in a contract usually ask for?
It may name a minimum limit, ask for a certificate, or ask to be named as an additional insured. Read it before you sign, and ask a licensed agent your questions if the wording is unclear.
Do life and health insurance agents need E&O insurance?
Carriers and agencies commonly ask for it before they contract with an agent, and a missed detail in a coverage recommendation is the kind of mistake E&O is built for. See E&O insurance for life and health agents to get a quote.
