Definition

Malpractice is professional negligence — the failure of a licensed professional to meet the standard of care expected of a reasonably competent member of that profession, resulting in harm to the person relying on those professional services. The term applies across a wide range of licensed professions, though it originated almost exclusively in the medical context.

1. Medical malpractice. The failure of a physician, surgeon, nurse, dentist, or other healthcare provider to exercise the degree of care, skill, and treatment that a reasonably competent practitioner in the same field would exercise under similar circumstances. Liability attaches when that failure causes measurable injury to the patient.

2. Legal malpractice. The failure of an attorney to exercise the competence and diligence reasonably expected of a qualified lawyer, resulting in harm to the client — typically the loss of a claim, defense, or legal right that competent representation would have preserved.

3. Professional malpractice generally. In modern usage, the term extends to any licensed professional — accountant, architect, engineer, financial advisor — whose substandard performance causes client harm. The governing standard in each field is defined by what a reasonably competent professional in that discipline would do, not by the general negligence standard applied to ordinary persons.

Malpractice is a species of negligence, not an independent tort. Its distinctive feature is the elevated duty of care that attaches to professional status. The plaintiff must typically establish: (1) the existence of a professional duty; (2) breach of the applicable professional standard; (3) causation; and (4) damages.

Common Language

Modern common usage (Wiktionary): The improper treatment of a patient by a physician that results in injury or loss; also, improper or unethical conduct by a professional or official person.

Historical common usage (Webster's 1913): Evil practice; illegal or immoral conduct; practice contrary to established rules; specifically, the treatment of a case by a surgeon or physician in a manner contrary to accepted rules and productive of unfavorable results.

The common usage of malpractice, both historical and modern, centers on medicine and implies something close to misconduct or wrongdoing. The legal meaning is more precise and less moralistic: malpractice does not require bad intent, dishonesty, or deliberate wrongdoing. A competent and well-intentioned professional can commit malpractice by falling below the standard of care through inattention, error, or ignorance. Researchers reading older sources should not assume that the moral coloring of "evil practice" or "illegal conduct" carries over into the tort analysis.

Common Confusion

Malpractice vs. negligence. Malpractice is professional negligence — negligence committed within the context of a professional relationship. Not every act of negligence by a professional constitutes malpractice; the question is whether the conduct at issue required the application of professional skill and judgment. A doctor who negligently drives a car is not committing malpractice. A researcher conflating the two terms in historical sources may find malpractice used loosely to describe any misconduct by a professional, not in the technical tort sense.

Malpractice vs. misconduct. Professional misconduct (or professional discipline) is a regulatory matter handled by licensing boards; malpractice is a civil liability matter handled in court. The same conduct may give rise to both, but the standards, procedures, and consequences are distinct. Historical sources, particularly pre-twentieth-century dictionaries, sometimes blur this line.

Core Elements

Applicable to all professional malpractice claims:

Professional duty. The defendant must owe a duty arising from a professional relationship with the plaintiff. The existence of licensure alone does not establish duty; a professional-client relationship must exist.

Standard of care. The applicable benchmark is what a reasonably competent professional in the same field, and in the same or similar circumstances, would have done. Expert testimony is almost always required to establish this standard.

Breach. The defendant's conduct must have departed from that standard. Honest error does not automatically constitute breach; the question is whether the error was one a reasonably competent professional would have avoided.

Causation. The breach must have caused the plaintiff's harm. In medical malpractice, this often requires proof that the negligent treatment — not the underlying condition — caused the injury. In legal malpractice, it typically requires a "case within a case": the plaintiff must show they would have prevailed but for the attorney's negligence.

Damages. Actual harm must result. Substandard professional performance that causes no measurable injury does not support a malpractice claim.

Recognized Forms

/SUBTYPES

Medical malpractice. The most litigated category. Covers physicians, surgeons, dentists, nurses, and allied healthcare providers. Subject to significant statutory modification in most jurisdictions, including damage caps, mandatory pre-suit procedures, and expert affidavit requirements.

Legal malpractice. Governed partly by professional responsibility rules (which set the underlying standard of conduct) and partly by tort law. Requires the plaintiff to demonstrate the lost legal outcome as part of the damages case.

Accounting malpractice. Arises when a licensed accountant's negligent audit, tax, or financial advisory work causes client harm. Third-party liability (to non-clients who rely on negligent work) is a recurring and contested issue in this subtype.

Dental malpractice. Analytically identical to medical malpractice but governed by dental practice standards. Often treated in case law as a branch of medical malpractice.

Nursing malpractice. Distinct from physician malpractice in that nurses are held to the standard of a reasonably competent nurse, not a physician. Scope-of-practice questions — what a nurse is authorized to do independently versus under physician supervision — frequently arise.

Why It Matters in Research

The historical sources indexed to this entry are largely unhelpful for malpractice research. Black's 1st Edition redirects to MALA PRAXIS (the Latin precursor), and the 2nd Edition entry retrieved here concerns malicious prosecution — an indexing artifact, not substantive content. Anderson's and Bouvier's entries in the retrieved material address malice and Latin maxims, not malpractice as a tort. Researchers working with pre-twentieth-century legal dictionaries should expect thin direct coverage and should instead consult entries under MALA PRAXIS, NEGLIGENCE, and PHYSICIAN.

The modern law of malpractice developed substantially in the twentieth century, with the explosion of medical malpractice litigation beginning in the 1960s and 1970s driving significant statutory reform. Researchers analyzing historical sources from before that period will find malpractice treated largely as a medical concept, with little systematic attention to legal or accounting malpractice as independent fields.

Jurisdictional variation is severe. Many states have enacted tort reform statutes that materially alter medical malpractice procedure and damages. These statutory overlays will not appear in general legal dictionaries and must be tracked through state-specific statutory and regulatory sources. Corpus researchers should treat any unmodified common-law description of medical malpractice as a baseline that state legislatures may have substantially displaced.

The standard-of-care question is the most contested element in most malpractice cases and is almost entirely expert-driven. Dictionary definitions are of limited utility here; the operative standard in any given case is defined by professional practice standards, clinical guidelines, specialty board requirements, and competing expert testimony.

Historical Dictionary Support

The historical dictionary record for MALPRACTICE as a term is sparse and largely derivative. Black's 1st Edition does not define the term independently, instead cross-referencing MALA PRAXIS — reflecting the late-nineteenth-century preference for Latin terminology in professional negligence matters. This cross-reference is itself instructive: it signals that malpractice was not yet fully anglicized as a legal term of art, and that researchers consulting older materials should look under the Latin form.

Webster's 1913 provides the most useful historical snapshot, defining malpractice primarily in medical terms ("the treatment of a case by a surgeon or physician in a manner contrary to accepted rules") with a secondary gesture toward general "evil practice." This confirms that, at the turn of the twentieth century, the medical context was the understood core of the term. The extension to legal, accounting, and other professional contexts is a twentieth-century development that the historical dictionaries do not reflect.

Bouvier's entries retrieved here address adjacent Latin concepts (malum prohibitum, malum in se) rather than malpractice directly, reinforcing that nineteenth-century legal lexicography organized professional negligence differently than modern doctrine does. Researchers should not read modern malpractice doctrine back into Bouvier's framework.

Jurisdictional Note

Medical malpractice is among the most heavily legislated areas of tort law. Most U.S. states have enacted statutory modifications — including caps on non-economic damages, mandatory pre-suit notice and review panels, shortened statutes of limitations, and expert witness qualification requirements — that significantly alter the common-law baseline. Legal malpractice doctrine is less statutorily modified but varies considerably in how courts handle the causation element, particularly the "case within a case" requirement.

design in general; the dictate of a wicked, depraved, and a malignant heart.1 Is not confined to homicide committed in cold blood, with settled design and premeditation, but extends to all cases of homicide, however sudden the occasion, when the act is done under such cruel circumstances as are the ordinary symptoms of a wicked, depraved, and malignant spirit." Includes not only anger, hatred, and revenge, but every other unlawful and unjustifiable motive. Is not confined to ill-will toward one or more individual persons, but is intended to denote an action flowing from any wicked and corrupt motive, a thing done malo animo, where the fact has been attended with such circumstances as carry in them the plain indication of a heart regardless of social duty, and fatally bent on mischief. Therefore, murder is implied from any deliberate or cruel act against another, however sudden. The words do not imply deliberation, or the lapse of considerable time between the malicious intent to take life and the actual execution of that intent, but they rather denote purpose and design, in contradistinction to accident and mischance.3 Whenever a homicide is shown to have been committed without lawful authority and with deliberate intent, it is sufficiently proved to have been with malice aforethought. It is not necessary to prove that any special or express hatred or malice was entertained by the accused toward the deceased. It is sufficient to prove that the act was done with deliberate intent, as distinct from an act done under the sudden impulse of passion, in the heat of blood, and without previous malice. See MURDER. Particular malice; personal malice. Particular malice is ill-will, grudge, a desire to be revenged on a particular person. Personal malice is spite against some particular individual. It is one of the two varieties of malice in fact, the other being what Blackstone terms "universal" malice, or malice against the world generally, without reference to individuals; as, where a person discharges a gun into a multitude, or starts out to kill and does kill the first man he meets." Malicious. Characterizes an act not only when it arises from personal spite, but when it is a wanton and intentional injury, when it is willful.7 14 Bl. Com. 198. 2 United States v.
