Legal Malpractice Statistics: What the Claims Data Shows

The table shows the top five practice areas by share of claims in the ABA Profile of Legal Malpractice Claims 2020 to 2023, with the change from the 2016 to 2019 edition as reported by ALPS, a lawyers' malpractice insurer.

Practice area	Share of claims (2020 to 2023)	Change from 2016 to 2019 edition (%)
Estate, trust, and probate	13.58%	Up 1.6
Real estate	13.19%	Up 0.81
Personal injury (plaintiff)	12.73%	Down 3.58
Family law	10.02%	Down 2.79
Collections and bankruptcy	8.84%	Up 0.27

In the ABA's 2020 to 2023 claims study, estate, trust, and probate work produced 13.58% of all reported legal malpractice claims, moving from fourth place in the prior study to first.

Rounding out the top ten, in order, were business transaction and commercial law, patent, trademark, and copyright, corporate and business organization, labor law, and criminal law, according to Minnesota Lawyer's summary of the study. The same summary noted that labor and intellectual property claims each rose by about 2.6% while criminal law fell by 2.2%.

In the prior edition covering 2016 to 2019, plaintiff personal injury and family law were the most frequent sources of claims. That shift matters for readers: if your problem involves a will, trust, or probate estate, you are in what is now the largest category. Our page on estate planning malpractice explains those claims, and our page on real estate attorney malpractice covers closings and title work.

The ABA groups alleged errors into broad categories. Substantive errors (not knowing or misapplying the law, missing a critical deadline, inadequate investigation, conflicts of interest) are the largest group, followed by administrative errors (calendaring, clerical mistakes, procrastination) and client relations errors (failing to follow instructions, failing to get consent).

Error category	Share (2020 to 2023)
Substantive errors	About 51%
Administrative errors	Nearly 25%

Source: ABA Profile of Legal Malpractice Claims 2020 to 2023, as reported by ALPS.

About 51% of alleged errors in the ABA's 2020 to 2023 legal malpractice claims data were substantive, meaning the lawyer allegedly failed to know or correctly apply the law, missed a critical deadline, investigated inadequately, or had a conflict of interest.

Minnesota Lawyer's summary reported notable increases in three specific error types compared with the prior study: failure to commence an action on time (up 2.73%), drafting errors (up 3.99%), and conflicts of interest (up 2.89%). ALPS wrote that conflict of interest claims and settlement-related claims are at an all-time high.

The ABA also tracks the activity the lawyer was doing when the error happened:

Activity	Share of claims (2020 to 2023)
Preparing, filing, or transmitting documents	35.66%
Commencing an action or proceeding	18.90%
Advice	13.25%
Settlement or negotiation	11.04%
Pre-trial or pre-hearing	6.89%

Deeds, leases, contracts, wills, trusts, and court filings are all "documents" in this sense, which is why drafting errors and missed deadlines show up so often in real claims.

Small practices generate most reported claims, largely because most law firms are small.

• 2020 to 2023: Firms of 1 to 5 attorneys were responsible for more than 52% of claims, according to ALPS. Minnesota Lawyer reported that this group also had the largest net decrease in claims, while firms with more than 500 lawyers saw a 6.48% increase.
• 2016 to 2019: A 2026 Kentucky Bar Association CLE paper by Lawyers Mutual of Kentucky, citing the ABA's 2016 to 2019 study, put the share for firms of one to five attorneys at 62%.

Law firms with 1 to 5 attorneys accounted for more than 52% of claims in the ABA's 2020 to 2023 legal malpractice study, down from 62% in the 2016 to 2019 study as cited by Lawyers Mutual of Kentucky.

Firm size also shapes how a claim plays out. A small firm is more likely to carry modest insurance limits, and a solo lawyer who retires or closes a practice may leave no active policy, which is why collectibility questions come up early in claims against small practices. See whether your lawyer has malpractice insurance.

Large firms are a different market. A separate study by the EPIC Law Firm Group, which polled 11 insurers covering more than 80% of AM Law 100 and NLJ 250 firms, found trusts and estates, business transactions, and corporate and securities work among the top practice areas producing claims against big firms, as reported by Minnesota Lawyer.

Summarizing the 2020 to 2023 Profile, Minnesota Lawyer reported that 82% of claims in the study resulted in no payment, and that the size of indemnity payments fell when claims were paid. Claims fail for many reasons: the client cannot prove the case within a case, the statute of limitations has run, or the loss is too small to justify an expert and trial.

At the other extreme, a Lockton report summarized by Minnesota Lawyer counted 83 publicly reported settlements or verdicts above $20 million involving law firms since the mid-1980s.

Only 83 publicly reported settlements or verdicts against law firms have exceeded $20 million since the mid-1980s, with a median of $34.5 million, according to Lockton data reported by Minnesota Lawyer. For individual cases, see our table of notable settlements and verdicts.

Individual insurers publish their own numbers. Lawyers Mutual Insurance Company of Kentucky reported these claim rates for the Kentucky lawyers it insures, in a CLE paper updated January 2026:

Year	Claims per 100 insured lawyers
2020	1.96
2021	1.94
2022	2.21
2023	2.32
2024	1.62

Source: Lawyers Mutual of Kentucky, Preparing for Legal Malpractice Claims (Kentucky Bar Association CLE, updated January 2026).

Lawyers Mutual of Kentucky reported 1.62 claims per 100 insured lawyers in 2024, down from 2.32 in 2023.

The same paper broke down 2024 Kentucky claims by practice area: real estate 27%, estate, trust, and probate 20%, plaintiff personal injury 20%, family law 11%, other 9%, and 3% or less for every remaining category. The paper noted that plaintiff personal injury and real estate have been two of the highest claim areas for Kentucky lawyers since 1990.

A malpractice claim asks for money. A bar grievance asks the state to discipline the lawyer. The two systems count different things, and the discipline numbers are far larger on complaints and far smaller on outcomes. Our guide to malpractice versus a bar complaint explains the difference.

National discipline (ABA survey, 2018)	Figure
Complaints received (45 states and D.C.)	83,073
Lawyers publicly disciplined	2,872
Suspended	1,374
Disbarred	631
Probation	339
Admonished, reprimanded, or censured	1,007

Source: ABA Survey on Lawyer Discipline Systems data for 2018, as reported by Lawyers Mutual Insurance Company of North Carolina.

In 2018, state disciplinary agencies received 83,073 complaints against lawyers and publicly disciplined 2,872, roughly one quarter of one percent of practicing lawyers in the reporting states.

State reports show the same pattern. In Minnesota in 2024, 27 lawyers received public discipline (5 disbarments, 14 suspensions, 8 reprimands) and 101 received private discipline, with communication, safekeeping client property, diligence, and fees the most common rule violations in admonitions, according to Minnesota Lawyer.

When a lawyer steals money rather than making a mistake, state client protection funds may reimburse clients. California's Client Security Fund paid $6.23 million in 2023, according to the State Bar of California. See our guide to getting money back from a client protection fund.

Keep in mind what these statistics cannot tell you. They do not say whether your lawyer made a mistake, whether the mistake cost you money, or what your claim is worth. A claim in a common category is not stronger because it is common, and a claim in a rare category is not weaker. The numbers are most useful for understanding what insurers and malpractice lawyers see every day, and why they ask the questions they do in a first consultation.

The data points to three practical lessons. First, the most common claims involve documents and deadlines, which are also the easiest mistakes to prove from paper records, so start by getting your case file. Second, most claims do not pay, so a strong claim needs a clear loss you can measure; our guide on what a case is worth walks through that. Third, deadlines matter: check the statute of limitations in your state now, not later.
