Mid-Size Firm (11-50 Attorneys) insurance guide
Layered programs and risk management credits for established firms with multiple practice areas.
Overview
Mid-size firms have crossed the threshold where insurance becomes a strategic function rather than a simple purchase. With multiple practice areas under one roof, the firm's risk profile is a blend of high-frequency, low-severity exposures from transactional work and low-frequency, high-severity exposures from litigation, securities, or real estate practices. Carriers price mid-size firms using detailed applications that break down revenue by practice area, require five to ten years of claims history, and evaluate the firm's risk management infrastructure including conflicts systems, engagement letter practices, and supervision protocols. The insurance program itself typically involves layered coverage: a primary professional liability policy supplemented by one or more excess layers from different carriers, creating a tower of coverage that spreads risk across the market.
Typical Coverage
Professional liability programs for mid-size firms commonly start at $1,000,000/$3,000,000 primary limits with one or two excess layers bringing total available limits to $5,000,000 to $10,000,000. Deductibles range from $10,000 to $50,000 per claim. Cyber liability limits of $2,000,000 to $5,000,000 are typical, often with separate sublimits for ransomware and social engineering. Employment Practices Liability limits of $1,000,000 to $3,000,000 reflect the larger employee count. A commercial umbrella of $3,000,000 to $5,000,000 sits above general liability, auto, and employers liability. Directors and Officers coverage of $1,000,000 to $3,000,000 protects the management committee.
Common Risks
Practice area concentration risk is the primary concern: a mid-size firm with a large real estate practice faces different exposure than one focused on employment defense. Carriers analyze revenue concentration and may impose sublimits or exclusions for high-risk practice areas. Lateral partner movements create prior-acts exposure and potential loss of institutional knowledge about open matters. Regulatory investigations and bar complaints increase in frequency with firm size. Cyber risk escalates as the firm maintains larger client databases, handles more wire transfers, and employs more staff with system access.
Typical Premium Range
$25,000 - $150,000 per year
Our Recommendations
Work with a broker who specializes in law firm insurance and can access multiple carriers for layered placements. Pursue risk management credits aggressively -- most carriers offer 5 to 15 percent premium reductions for firms with documented intake procedures, engagement letter templates, conflicts systems, and attorney supervision protocols. Review your practice area mix annually and discuss emerging exposures with your broker before renewal. Consider a dedicated risk management partner or committee responsible for claims reporting, engagement letter compliance, and insurance program oversight. Negotiate multi-year rate guarantees when the firm's claims history supports it.
Frequently asked questions
What is a layered insurance program and why do mid-size firms need one?
A layered program stacks multiple policies to achieve higher total limits than any single carrier would provide alone. The primary layer handles the first portion of a claim, and excess layers respond sequentially above it. Mid-size firms need layered programs because their exposure from high-value matters can exceed what a single carrier will underwrite, and spreading risk across carriers often produces better pricing than a single large policy.
How do risk management credits work?
Carriers offer premium discounts -- typically 5 to 15 percent -- for firms that implement formal risk management practices. Qualifying activities include maintaining a written conflicts-check system, using standardized engagement and disengagement letters, requiring CLE on ethics and malpractice avoidance, and designating a risk management partner. Some carriers provide their own risk management tools and hotlines as part of the policy.
Should we carry D&O coverage in addition to malpractice insurance?
Yes. Malpractice insurance covers claims arising from legal services provided to clients. D&O coverage addresses claims from within the firm -- partner disputes over compensation, allegations of mismanagement, breaches of fiduciary duty by the management committee, and regulatory investigations targeting firm leadership. These are distinct exposures that require separate policies.
