Attorneys are highly trusted when it comes to legal matters. In reality, mistakes happen — they’re rarely malicious, but a single oversight can cost a client or third party a lot of money.

That exposure — whether monetary loss, lost property, or damage to reputation — is why attorneys carry Professional Liability Insurance (also called errors and omissions insurance).
Attorneys Professional Liability Insurance covers the attorney or firm if a client alleges negligence, missed deadlines, improper advice, or other professional errors. Common examples include misfiling paperwork, misstating parts of a law or procedure, or failing to file on time.

Even non-monetary harms, such as reputational damage, can lead to claims and future financial loss — professional liability policies help respond to those risks and related defense costs.
Who needs this coverage
Solo practitioners, small firms, large law firms, legal aid programs, and in-house counsel can all face professional liability exposures. Larger practices typically see greater aggregate exposure because more attorneys and staff handling matters increases the chance of an error and the number of affected clients. Firms looking for practice-specific policy options can review Attorneys Professional Liability Insurance to compare coverages and limits.
What it typically covers
Policies usually cover legal defense costs, settlements, and judgments arising from alleged professional errors. Coverage can extend to negligent acts, omissions, and certain breach-of-duty claims. Insurers evaluate underwriting factors such as firm size, practice areas, claims history, and risk management procedures when issuing terms.
Common exclusions or limitations
Standard exclusions often include intentional wrongdoing, criminal acts, bodily injury/property damage better covered by general commercial liability, and some regulatory fines. Clear understanding of policy exclusions and endorsements is essential when choosing limits or adding extensions like cyber liability or extended reporting periods.
Risk examples and related coverages
A common risk scenario: a missed filing deadline in a real estate closing that leads to a client lawsuit for financial loss. Firms should consider related coverages (commercial liability, cyber protection, and property coverage for office assets) as part of broader risk management.
Larger firms and compliance
If you operate multiple offices or a multi-attorney firm, coordinate professional liability with your general liability and any specialty programs — for example, see Law Firms Insurance for combined risk considerations. For attorneys working in legal aid or public-interest settings, there are tailored options described in Legal Professional Liability programs.
How to buy and manage coverage
When shopping for coverage, first consult with a local licensed insurance agent who specializes in Professional Liability insurance. This agent will help navigate state requirements, explain underwriting factors and exclusions, and find appropriate limits and endorsements. Maintain good risk-management practices — clear engagement letters, calendaring protocols, and staff training — to help reduce both the likelihood of claims and potential premium impact.
For more detailed program options including errors-and-omissions features, consider reviewing resources such as Errors and Omissions Program for Lawyers Insurance to compare available endorsements and limits.
Frequently Asked Questions
Do all attorneys have to carry professional liability insurance?
Requirements vary by state and employer. Some jurisdictions or firms mandate coverage, while others strongly recommend it; check local rules and firm policies.
Will this insurance cover disciplinary action or regulatory fines?
Most professional liability policies cover defense and civil claims for negligence, not disciplinary proceedings or certain regulatory fines. Review policy language and exclusions carefully.
How do limits and deductibles affect my coverage?
Higher limits provide broader financial protection but typically increase premiums; higher deductibles lower premiums but raise out-of-pocket cost when a claim occurs. Discuss options with your agent to balance protection and cost.
