Lawyer Malpractice Insurance: How Much Coverage Do You Need and Best Providers

The Quick Answer

For a new solo attorney in most practice areas, a $1,000,000 per-claim / $3,000,000 annual aggregate claims-made policy from a reputable carrier (ALPS, USI Affinity, Chubb, or your state bar's endorsed provider) is the appropriate starting coverage. Annual cost for most solo attorneys: $2,000–$5,000/year for low-to-moderate-risk practice areas (estate planning, business transactional, immigration, family law). Higher-risk areas (personal injury plaintiff, securities litigation, commercial litigation) cost $4,000–$8,000+/year. Apply for coverage 4–6 weeks before opening and set your retroactive date to your first day of practice or earlier. Never purchase a policy with a retroactive date later than the earliest date you could have provided legal advice, even informally.

Claims-Made vs Occurrence Policies: The Critical Distinction

This is the most important concept in attorney malpractice insurance, and getting it wrong leaves you unprotected. A claims-made policy covers claims that are both: (1) based on an act or omission that occurred after the retroactive date, AND (2) reported to the insurer while the policy is active. If you cancel a claims-made policy and a claim is made six months later for work you did while the policy was active, you are NOT covered — unless you purchased a tail (extended reporting period). An occurrence policy covers any claim arising from an act that occurred while the policy was active, regardless of when the claim is filed — even 10 years later. Occurrence policies are significantly more expensive and are rarely available for attorney malpractice. All major solo attorney malpractice carriers offer claims-made policies. The implication: when you change carriers or retire, you must purchase a tail policy to maintain coverage for prior work. Tail coverage typically costs 150–300% of your final annual premium.

The Retroactive Date: Why It Must Be Set Correctly

The retroactive date on a claims-made policy is the earliest date from which prior acts are covered. If your policy has a retroactive date of January 1, 2026, and you're sued for something you did in December 2025, you're not covered. For a brand-new attorney who has never practiced privately, set the retroactive date to your first day of opening your solo practice — no prior acts to cover. If you previously worked at a firm and you're going solo, you need to think carefully: if your former firm's malpractice carrier is covering your prior acts at the firm (most firm policies cover former associates for work done while at the firm), you may only need coverage from your solo start date. If you practiced independently before forming your current firm, or if you're uncertain about prior act coverage, set the retroactive date as early as possible — even if it slightly increases your premium. A retroactive date error is among the most costly mistakes in attorney insurance.

ALPS: The Largest Attorney-Owned Malpractice Insurer

ALPS (alps.com — Attorney Liability Protection Society) is the nation's largest attorney-owned malpractice insurance carrier and covers solo attorneys in all 50 states and D.C. ALPS specializes exclusively in attorney malpractice insurance, which means their underwriters understand law firm operations in a way that generalist insurers don't. Key ALPS features: online quote and application in under 30 minutes, competitive pricing for new solos ($1,800–$4,500/year for $1M/$3M coverage depending on practice area), risk management resources included with every policy (CLE, practice management guidance, a risk management hotline), and a dedicated claims team with legal malpractice expertise. ALPS is particularly strong for solo attorneys in transactional practice areas (estate planning, real estate, business law) and litigation. They also offer prior acts coverage and tail coverage. Most state bar associations recommend or endorse ALPS as a preferred carrier — check if yours does.

USI Affinity and Other Major Solo Attorney Carriers

USI Affinity (usiaffinity.com/legal) is a major insurance broker that places attorney malpractice coverage through multiple carriers (Chubb, CNA, Travelers, Hanover) and offers a bar association member discount program. USI Affinity's multi-carrier access means they can often find competitive pricing for attorneys in higher-risk practice areas where ALPS may be more expensive. Chubb's professional liability division (formerly ACE) offers competitive solo attorney coverage with strong claims handling and higher policy limits (up to $5M/$10M for solos who need it). Other notable carriers: Philadelphia Insurance Companies (specializes in smaller firms), Continental Casualty/CNA (covers litigation-heavy practices), and your state bar's endorsed insurer (many state bars negotiate discounted group rates for members — always check this first). Get quotes from at least three carriers before purchasing — premium variations of 20–40% for identical coverage are common.

Coverage Limits, Deductibles, and Common Exclusions

Standard coverage limits for solo attorneys: $250,000/$750,000 (minimum, adequate only for lowest-risk practices), $500,000/$1,500,000 (low risk, limited assets), $1,000,000/$3,000,000 (standard recommendation for most solos), $2,000,000/$4,000,000 (higher-risk practice areas or attorneys with significant personal assets to protect). Deductible options: $0, $1,000, $2,500, or $5,000 per claim — a higher deductible reduces your premium but means you pay the first portion of any claim costs. Common exclusions to watch for: dishonesty/fraud (no carrier covers intentional wrongdoing), business disputes with your own clients over fees (fee arbitration is typically excluded), claims arising from non-legal services you provide, and claims from prior acts before the retroactive date. Read your policy exclusions carefully — a malpractice policy that excludes your most common practice area's risk profile is inadequate regardless of its premium.
