What Insurance Types Are Needed For a Law Firm?
Professional Liability Insurance (Legal Malpractice Insurance) | Covers claims arising from legal errors, missed filing deadlines, inadequate research, conflicts of interest, and negligent legal advice that causes financial harm to clients. Oregon and Idaho mandate this coverage by law, and many state bars strongly recommend it for all practicing attorneys. | $1 to $2 million per claim with $2 to $3 million aggregate coverage is standard for solo practitioners and small firms. Larger firms handling complex matters should carry $5 million or more depending on practice area and client base. | An attorney missed the statute of limitations deadline for filing a personal injury lawsuit, costing the client a potential $800,000 settlement. The client sued for malpractice, resulting in $750,000 in damages plus $180,000 in legal defense costs. Professional liability insurance covered the full $930,000, protecting the firm from financial ruin. |
Protects law firms from data breach costs when confidential client information is compromised, covering notification expenses, credit monitoring, regulatory fines, and ransom payments from cyberattacks. The coverage handles both your firm's recovery costs and client lawsuits from the breach. | Small firms should carry $1 to $2 million in coverage, with $3 to $5 million recommended for practices handling sensitive financial or healthcare-related legal matters. | Hackers accessed a family law firm's client database containing 450 cases with Social Security numbers, financial records, and custody details. The breach cost $280,000 in notification expenses, $95,000 in credit monitoring, $340,000 in regulatory fines, and $215,000 defending client lawsuits. Cyber liability insurance covered all $930,000 in breach-related expenses. | |
Covers medical expenses and lost wages for work-related injuries or illnesses affecting associates, paralegals, legal assistants, and administrative staff. Most states mandate this coverage once you hire your first employee. | Coverage amounts are set by state law and calculated based on payroll and employee classification codes. Annual premiums typically range from $400 to $1,500 per employee depending on your state and job duties. | A legal assistant developed severe carpal tunnel syndrome requiring surgery after years of document preparation and typing. Medical treatment cost $38,000, and she missed 12 weeks of work totaling $18,000 in lost wages. Workers' compensation covered all $56,000, and the employee couldn't sue the firm for additional damages. | |
Covers defense costs and settlements for wrongful termination, discrimination, harassment, and retaliation claims filed by associates, paralegals, and staff. Law firms face elevated exposure due to up-or-out partnership tracks, billable hour pressures, and power dynamics between senior partners and junior attorneys. | Firms with five or more employees should carry $1 million per claim with $2 million aggregate. Solo practitioners with one or two employees can start with $500,000 coverage. | A former associate sued the firm for gender discrimination and wrongful termination, claiming she was passed over for partner due to her pregnancy and pushed out for refusing excessive billable hour quotas. Legal defense costs reached $175,000, and the firm settled for $325,000 to avoid trial. EPLI covered the entire $500,000 claim. | |
Fidelity Bond | Protects against employee theft or embezzlement from client trust accounts (IOLTA), covering paralegals, associates, or bookkeepers who misappropriate settlement funds, retainer deposits, or escrow money. Many state bars recommend fidelity bonds for firms maintaining client trust accounts. | Small firms should carry $100,000 to $250,000 coverage, with amounts increasing based on typical trust account balances. Firms regularly holding $500,000 or more in client funds should carry $500,000 to $1 million. | A bookkeeper at a personal injury firm stole $385,000 from the client trust account over 18 months, creating false ledger entries and transferring settlement funds into shell companies. The fidelity bond reimbursed the full $385,000, allowing the firm to make clients whole and avoid disbarment. |
Covers losses from external fraud targeting law firm finances, including forged settlement checks, fraudulent wire transfer requests impersonating clients or opposing counsel, and social engineering scams exploiting real estate closings. Cybercriminals increasingly target law firms handling escrow funds, estate settlements, and business transactions. | Small firms should carry $250,000 to $500,000, with $1 million recommended for practices regularly handling large settlements, real estate closings, or estate distributions. | A cybercriminal monitoring a real estate transaction sent a spoofed email impersonating the title company, instructing the firm to wire $425,000 in closing funds to a fraudulent account. Crime insurance covered the $425,000 loss plus $45,000 in forensic investigation costs, totaling $470,000 in reimbursement to the client. | |
Lawyer Business Insurance Requirements
Your law firm's insurance requirements depend on three main factors: where you practice, who your clients are, and where you lease office space. Below you'll find which coverages are mandated, who's doing the mandating, and what policy limits you'll need to meet.
Workers' Compensation Insurance | Most states mandate this coverage once you hire your first employee, including associates, paralegals, or administrative staff, with penalties including fines up to $10,000 per employee, criminal charges, and personal liability for all injury costs. Non-compliance can result in business license suspension and expose you to lawsuits from injured employees. | State law sets minimum coverage amounts based on your payroll and employee classification codes. Annual premiums range from $400 to $1,500 per employee depending on your state and job duties. |
Professional Liability Insurance (Legal Malpractice Insurance) | Oregon and Idaho mandate malpractice coverage by law for all practicing attorneys, while most other states require disclosure to clients if uninsured. Corporate clients, government entities, and court-appointed panels typically require proof of coverage before engagement. | Oregon requires $300,000 per claim minimum, while Idaho mandates $100,000 per occurrence. Corporate and institutional clients typically require $1 to $2 million per claim, with high-value clients requiring $3 to $5 million. |
All 49 states except New Hampshire mandate commercial auto coverage for business-owned vehicles used for court appearances, client meetings, or depositions. Personal auto policies don't satisfy state law for business use. | State minimum liability limits range from 25/50/10 to 30/60/25 split limits. Law firms should carry $500,000 to $1 million combined single limit for adequate protection. | |
Commercial landlords require general liability for office leases, and many municipalities mandate it for business licensing. Corporate and government clients often require proof of coverage before allowing attorneys on-site for meetings. | Standard requirement is $1 million per occurrence and $2 million aggregate. High-value clients or premium office buildings may require $2 to $3 million per occurrence with additional insured endorsements. | |
Fidelity Bond | Many state bars require or strongly recommend fidelity bonds for firms maintaining client trust accounts (IOLTA) to protect against employee theft. Some states mandate minimum coverage as a condition of maintaining trust accounts. | Small firms typically need $100,000 to $250,000 in coverage. State bar minimums vary, with amounts increasing based on average trust account balances and transaction volumes. |
Cyber Liability Insurance | Corporate clients, financial institutions, healthcare providers, and government contractors increasingly require cyber coverage before engagement, particularly for firms handling sensitive data. Client engagement agreements often mandate proof of coverage before case acceptance. | Corporate clients typically require $1 to $2 million as a baseline. Healthcare clients subject to HIPAA or financial institutions may require $3 to $5 million with specific data breach response protocols. |
Landlords require commercial property coverage for firms leasing office space and lenders mandate it for financed office improvements or equipment purchases. The coverage protects the landlord's building investment and lender's collateral. | Coverage amount is based on replacement cost of tenant improvements, furniture, equipment and law library. Amounts typically range from $50,000 to $500,000 depending on office size and contents value. | |
High-value corporate clients, Fortune 500 companies and major financial institutions require umbrella coverage for firms providing ongoing counsel or handling high-stakes litigation. This provides additional liability coverage above base policies. | High-value clients typically require $3 to $5 million in total liability coverage. Premium clients or firms handling cases with exposure over $10 million may require $5 to $10 million in umbrella coverage. | |
How To Ensure Lawyer Business Insurance Requirements Are Met
Buying the policy is easy, but proving you have it to everyone who needs confirmation is the hard part. Below are the steps for getting certificates of insurance, submitting them to the right parties, and updating them when policies renew.
- 1Request certificates of insurance (COI) from your insurance provider
Contact your insurance carrier immediately after purchasing each policy to request Certificates of Insurance, which most providers deliver via email or online portal within minutes to hours. Law firms need COIs to prove coverage to corporate clients before engagement, landlords before lease signing, state bars for trust account authorization, and courts for appointed cases.
- 2Verify coverage amounts match client contract and bar requirements
Review each COI against specific requirements in your client engagement agreements, state bar minimums, and lease contracts to confirm policy limits meet or exceed mandated amounts. Pay particular attention to malpractice policy limits (Oregon requires $300,000 minimum), cyber coverage amounts for clients with data protection requirements, and aggregate limits that could exhaust mid-year with multiple matters.
- 3Add clients or landlords as additional insured when required
Corporate clients and commercial landlords often require your law firm to add them as additional insured parties on your general liability policy, costing $25 to $100 per endorsement with 24 to 48-hour processing. Request updated COIs showing the additional insured endorsement immediately after processing, since clients won't allow you to begin work without proof they're protected under your policy.
- 4Submit proof of insurance to clients, courts, bars and landlords
Provide COIs to corporate clients before signing engagement letters, to state bars when applying for trust account authorization, to landlords before lease execution, and to courts for appointed counsel eligibility. Maintain a digital filing system organizing COIs by policy type and expiration date for quick access when clients request proof during conflicts checks or engagement processes.
- 5Set automatic renewals and proactively update all parties
Establish calendar reminders 60 to 90 days before each policy renewal to obtain updated COIs, particularly for malpractice coverage which state bars require for continuous trust account maintenance. Proactively send renewed COIs to all active corporate clients, landlords, bar authorities, and courts where you maintain appointment eligibility, since lapses can trigger engagement violations, trust account suspension, or removal from appointment lists.
