1. Attorney Duty, Standard of Care, and Breach
A legal malpractice claim begins with the attorney-client relationship. That relationship creates a duty. The duty is to perform legal services with the competence of a reasonably competent attorney.
What Is the Scope of an Attorney'S Duty to a Client?
An attorney owes a duty of care only to clients. The scope of the duty is defined by the scope of the representation. An attorney retained only to review a contract has no duty regarding litigation strategy in a related case. Attorneys owe duties of loyalty, confidentiality, and communication beyond competence. Breaching any of these duties can form the basis of a legal malpractice claim.
Legal malpractice counsel evaluates whether an attorney-client relationship existed at the time of the alleged negligence, analyzes the scope of the attorney's duty based on the terms of the representation, and advises on the evidentiary record needed to establish the attorney-client relationship in a disputed engagement.
Breach of Fiduciary Duty and Conflict of Interest Claims
Attorneys are fiduciaries whose duty of loyalty is governed by the Rules of Professional Conduct. Conflicts of interest occur when personal interests or other loyalties interfere with duties to the current client. Representing opposing parties without informed written consent is a per se violation. A fiduciary breach may support fee forfeiture even without a compensatory damages award.
Breach of fiduciary duty counsel evaluates the attorney's conflict of interest disclosures and waivers, advises on the standards for breach of fiduciary duty claims under state professional liability law, and advises on the remedies available when an attorney's conflict caused the client to lose value that a loyal attorney would have preserved.
2. Causation and Damages in Legal Malpractice Claims
Proving that an attorney breached a duty is not enough. The client must prove that the breach caused the client's loss. This causation requirement is where many legal malpractice claims fail.
The Case within a Case: How Causation Is Proved in Litigation Malpractice
In litigation malpractice, the client must satisfy the but-for standard. The client would have prevailed in the underlying case but for the attorney's negligence. The malpractice plaintiff must essentially retry the underlying lawsuit as the case within a case. Expert testimony on the underlying law is almost always required. Causation is not presumed from the attorney's error alone.
Accounting malpractice counsel evaluates the causation theory in litigation malpractice claims, develops the expert testimony strategy for the case within a case analysis, and advises on the proof standards for showing that the underlying case would have succeeded absent the attorney's professional liability failure.
Damages: What a Legal Malpractice Plaintiff Can Recover
A successful legal malpractice plaintiff can recover actual damages. Consequential damages are recoverable when foreseeable and flowing directly from the attorney's breach. In litigation malpractice, actual damages are the value of the judgment the client would have obtained. Punitive damages require proof of intentional misconduct or gross negligence.
Awarding damages counsel evaluates the damages model in a proposed legal malpractice claim, advises on the jurisdictional standards for consequential and punitive damages in attorney negligence cases, and advises on the evidence needed to establish the value of the lost outcome in both litigation and transactional malpractice claims.
3. Filing a Legal Malpractice Claim
Legal malpractice claims are governed by state law. The procedural requirements vary by jurisdiction. Missing a deadline or filing in the wrong court can extinguish the claim entirely.
When Does the Statute of Limitations Begin to Run on a Malpractice Claim?
Every state imposes a statute of limitations on legal malpractice claims. Most states apply the discovery rule. The limitations period begins when the client discovers, or reasonably should have discovered, the attorney's negligence. The continuous representation rule tolls the limitations period while the attorney continues to represent the client in the matter that gave rise to the malpractice. Clients who delay in consulting malpractice counsel risk losing their claim to limitations.
Appeals counsel evaluates the applicable statute of limitations and discovery rule in the jurisdiction where the malpractice occurred, advises on tolling provisions including the continuous representation rule, and advises on the procedural steps required to preserve a legal malpractice claim before the limitations period expires.
Expert Testimony, Pleading Requirements, and the Malpractice Trial
Legal malpractice plaintiffs almost always need an expert witness. The expert must be a licensed attorney with experience in the relevant practice area. The expert testifies on the applicable standard of care and how the defendant's conduct fell below that standard. Most states require an affidavit of merit or certificate of merit before the case can proceed. Failure to comply can result in dismissal. The plaintiff bears the burden of proof by a preponderance of the evidence.
Appellate litigation counsel advises on the pleading and expert disclosure requirements in the jurisdiction where the malpractice claim is filed, evaluates the affidavit of merit requirements applicable to the proposed claim, and advises on trial strategy for both plaintiffs and defendants in legal malpractice litigation.
4. Attorney Defenses and Risk Management
Attorneys who face legal malpractice claims have several available defenses. Each defense must be evaluated against the specific facts of the alleged negligence.
What Defenses Are Available to an Attorney Facing a Malpractice Claim?
The most common defense is that the attorney met the standard of care. Comparative fault may reduce recovery where the client's own conduct contributed to the loss. Judgment rule defenses apply when the attorney made a tactical choice within the range of reasonable professional judgment. Causation defenses argue that the client's loss would have occurred regardless of the attorney's conduct.
Medical malpractice litigation counsel represents attorneys in legal malpractice defense proceedings, advises on the judgment rule defense and the standard of care expert strategy, and advises on the fee forfeiture and disgorgement exposure that arises when a client asserts breach of fiduciary duty alongside a legal malpractice claim.
Malpractice Insurance, Bar Complaints, and Attorney Risk Management
Most states require attorneys to disclose whether they carry professional liability insurance. Bar complaints are a parallel avenue for attorney discipline. A bar complaint can result in suspension, disbarment, or reprimand. Bar records can provide important evidence in a subsequent malpractice case. Attorneys can reduce their exposure through clear engagement letters, conflict checks at intake, and calendar systems for deadlines. Each of those practices reduces the probability of a malpractice claim arising from the representation.
Bad faith insurance counsel evaluates the professional liability insurance coverage available in a legal malpractice case, advises on the interaction between bar disciplinary proceedings and civil malpractice litigation, and advises on the risk management practices that attorneys can implement to reduce their exposure to legal malpractice claims.
