Professional Malpractice (Accountants, Architects, Engineers, Brokers and Other Professionals)

A claim that a licensed professional other than a doctor or lawyer fell below the standard of care of their profession and caused a financial or physical loss.

Informational only - this is not legal advice. These definitions explain general legal vocabulary in plain English. They are not advice about your situation, reading them creates no attorney-client relationship, and the law differs from state to state and changes over time. For advice you can rely on, speak to a lawyer licensed in your state.

What it means

Professional malpractice, or professional negligence, is the claim a client or other injured person brings when an accountant, architect, engineer, real estate broker or appraiser, insurance agent, financial planner or other professional does their work carelessly and causes a loss. Doctors and lawyers have their own entries (medical malpractice, legal malpractice). The structure is the same across professions: the professional owed a duty, the duty was measured by the standard of care of a reasonably competent member of that profession in similar circumstances, the professional breached it, and the breach caused damages. Because the standard is professional rather than ordinary care, nearly every case requires an expert in the same field to say what a competent professional would have done, and several states require a certificate or affidavit of merit from such an expert before the case may proceed.

Each profession adds its own rules. An accountant is measured against generally accepted accounting principles and auditing standards and the AICPA Code of Professional Conduct, and states differ on whether a third party who relied on an audit, such as a lender, can sue the auditor who had no contract with them. Architects and engineers are judged by the standards of their licensing boards and professional codes, and construction claims against them face the same statutes of repose and economic loss rules as other construction defect claims. Insurance agents and brokers can be liable for failing to procure the coverage the client asked for or for misdescribing a policy. Real estate agents owe statutory disclosure duties and, as agents, fiduciary duties to their own client. Most professions are overseen by a state licensing board that can discipline a licensee on a complaint; a board complaint is free and public but produces no compensation, and the two tracks are independent.

Damages are usually economic: the tax penalty an accountant's error caused, the cost to fix a design defect, the uncovered loss an agent's failure left, the money a bad appraisal cost. Limitation periods run from when the client discovered or should have discovered the error in most states, but some professions have shorter periods or repose statutes. Many professionals carry errors-and-omissions insurance, which is the practical source of recovery, and most engagement letters now contain limitation-of-liability or arbitration clauses that the court will examine before anything else.

Where this comes from

Professional negligence is state common law, with the professional standard of care stated in Restatement (Second) of Torts § 299A. Accountant liability to third parties: compare Ultramares Corp. v. Touche, 174 N.Y. 170 (1931) (privity), Restatement (Second) of Torts § 552 (known users), and the states that apply ordinary foreseeability. Auditing and accounting standards: AICPA Statements on Auditing Standards and the Code of Professional Conduct; for public companies, PCAOB standards under the Sarbanes-Oxley Act, 15 U.S.C. § 7201 et seq. Licensing and discipline: each state's professional practice acts and boards. Certificate-of-merit and repose requirements: the civil procedure codes of the states that impose them.

When people hire a lawyer for this

Gather the engagement letter, every report, drawing, return or policy the professional produced, and your communications with them, and see a lawyer before you confront the professional or file a licensing complaint, since what you say in a complaint can be used in the civil case. Ask the lawyer whether your state requires an expert certificate before filing and how quickly one can be obtained. Fee arrangements vary: contingency fees are common where the loss is large and documented, hourly where liability is clear but damages are modest. A licensing board complaint is worth filing in addition to, not instead of, a claim when the conduct was serious.

Worried about the cost? A lawyer can be hired for one part of a case only (limited-scope representation), may be paid from what a claim recovers (contingency fee), or may be free through a pro bono program or legal aid; a court can also waive its own filing fees.
