Cost Guides

What does law firm insurance cost? Typical ranges, key pricing factors, and tips to reduce your premiums.

Legal Malpractice Insurance Cost$2,500-$25,000/year per attorney
Legal malpractice insurance (professional liability) is the most critical coverage for any law firm and often the largest insurance expense. Premiums vary dramatically based on practice area, with plaintiff personal injury firms paying far less than firms handling securities litigation, real estate transactions, or intellectual property. Most firms should expect malpractice insurance to represent 40 to 60 percent of their total insurance spend.
Cyber Insurance Cost for Law Firms$1,500-$12,000/year
Law firms are high-value targets for cyberattacks due to the sensitive client data they hold, including financial records, intellectual property, and privileged communications. Cyber insurance covers breach response costs, ransomware payments, business interruption, and third-party liability from data breaches. Premiums have stabilized after significant increases in 2021-2023 but remain elevated compared to pre-pandemic levels.
BOP Cost for Law Firms$750-$3,500/year
A Business Owner's Policy bundles general liability and commercial property coverage into a single, cost-effective package tailored for small to mid-size businesses. For law firms, a BOP covers common risks like client slip-and-fall injuries at the office, property damage, and business interruption. It is one of the most straightforward and affordable policies a firm will purchase.
EPLI Cost for Law Firms$2,000-$10,000/year
Employment Practices Liability Insurance protects law firms against claims from employees alleging wrongful termination, discrimination, sexual harassment, or retaliation. Even firms with strong HR practices face EPLI exposure because employment claims are common, expensive to defend, and often unrelated to whether the firm actually did anything wrong. EPLI is particularly important for firms with five or more employees.
Workers Comp Cost for Law Firms$500-$5,000/year
Workers' compensation insurance is required in nearly every state for firms with employees and covers medical expenses and lost wages for work-related injuries or illnesses. Law firms are classified as low-risk office environments, which keeps premiums modest compared to most industries. However, firms must still comply with state requirements, and failure to carry coverage can result in significant penalties.
D&O Insurance Cost for Law Firms$2,500-$15,000/year
Directors and Officers insurance protects the personal assets of law firm partners, managing directors, and officers against claims alleging mismanagement, breach of fiduciary duty, or other wrongful acts in their leadership capacity. This coverage is distinct from malpractice insurance, which covers professional legal services. D&O is especially relevant for firms structured as corporations or those with outside investors, lenders, or complex governance structures.
Umbrella Insurance Cost for Law Firms$1,000-$5,000/year for $1M-$5M in limits
Commercial umbrella insurance provides additional limits above underlying policies like general liability, auto liability, and employer's liability. For law firms, an umbrella policy is a cost-effective way to protect against catastrophic claims that exceed primary policy limits. Umbrella coverage typically kicks in only after the underlying policy limits are exhausted.
Tail Coverage Cost125-300% of the final year's annual premium (one-time cost)
Tail coverage (extended reporting period) allows a law firm to report claims after a claims-made policy has been cancelled or non-renewed. This is essential when a firm dissolves, an attorney retires, or when switching carriers with a gap in retroactive dates. Tail coverage is typically purchased as a one-time premium and provides coverage for a defined period, often one to six years or unlimited.
Insurance Cost for Solo Practitioners$4,000-$15,000/year for a comprehensive package
Solo practitioners face the same insurance requirements as larger firms but must bear the entire cost individually, making it important to prioritize coverages and find the most efficient way to build a protection program. The good news is that solos in lower-risk practice areas can assemble a solid insurance portfolio for a manageable annual cost. The priority order is typically malpractice first, then general liability or BOP, then cyber.
Total Insurance Budget for a Mid-Size Firm$75,000-$350,000/year total across all coverage lines
A mid-size law firm (10 to 50 attorneys) needs a comprehensive insurance program covering professional liability, property, cyber, employment practices, and several other lines. Budgeting accurately requires understanding how each coverage line contributes to the total cost and where there are opportunities for efficiency. Most mid-size firms should allocate between 2 and 4 percent of gross revenue to insurance premiums.
