What Is Legal Malpractice Insurance?

Legal malpractice insurance, also known as professional liability insurance for lawyers, protects attorneys against claims of negligence, errors, or failure to perform professional duties. These policies cover:
  • Legal defense costs (even for frivolous claims)
  • Settlements or judgments
  • Disciplinary proceedings (in some cases)
Why Do Illinois Lawyers Need Malpractice Insurance?
  • Mandatory in Some Cases: While Illinois doesn’t require all lawyers to carry malpractice insurance, some firms or clients (especially in corporate law) may mandate it.
  • High Risk of Claims: Common malpractice claims include missed deadlines, conflicts of interest, and poor client communication.
  • Financial Protection: A single lawsuit can cost $50,000+ in legal fees, even if you win.
  • Reputation Management: Insurance often includes PR support to mitigate reputational damage.
Types of Legal Malpractice Insurance Coverage in Illinois

1. Claims-Made Policies (Most Common)
  • Covers claims only if both the incident and the claim occur during the policy period.
  • Requires "tail coverage" (extended reporting endorsement) if you switch insurers or retire.
2. Occurrence Policies
  • Covers any claim arising from an incident during the policy period, even if reported later.
  • More expensive but provides long-term protection.
3. Additional Coverages to Consider
  • Cyber Liability Insurance (for data breaches)
  • Defense Costs Outside Limits (so legal fees don’t erode your coverage)
  • Prior Acts Coverage (for claims related to work done before the policy started)
