Professional Liability Insurance for Lawyers
Lawyers professional liability insurance, often called legal malpractice or errors and omissions (E&O) coverage, protects an attorney or firm when a client claims that their legal work caused harm. It pays for legal defense and any settlement, even on a claim that turns out to be groundless. For lawyers, defending a malpractice allegation is expensive on its own, which is what this coverage is built to absorb.
What lawyers professional liability covers
The coverage responds to claims arising from the legal services you provide. Common triggers:
- Negligence or errors in handling a matter
- Missed deadlines or a blown statute of limitations
- Conflicts of interest
- Failure to know or apply the law to a client's situation
- Inadequate or disputed advice the client relied on
It pays defense costs, frequently the largest expense even when the underlying claim fails, plus settlements or judgments up to your limit.
Why lawyers carry it
- Bar and court requirements. Some states and courts require attorneys to carry malpractice coverage or to disclose whether they do; requirements vary by jurisdiction, so check your state bar.
- Client expectations. Sophisticated clients often expect proof of coverage.
- The nature of the work. Deadlines, fiduciary duties, and high-stakes outcomes make legal work a natural target for "your mistake cost me" claims.
How it differs from general liability
Legal malpractice is not general liability. GL covers bodily injury and property damage, for example a client injured in your office. It does not cover an error in your legal work. A firm with a physical office usually needs both, with GL often bundled into a business owner's policy (BOP) and professional liability written as a standalone policy.
What drives the premium
- Firm revenue and number of attorneys
- Practice areas (some areas of law carry more exposure than others)
- Coverage limits and deductible
- Claims history
- Retroactive date and years of continuous coverage
Legal malpractice is written on a claims-made basis, so continuous coverage and the retroactive date are as important as the limit. When you change insurers or wind down a practice, ask about tail coverage (an extended reporting period) so late claims on past matters remain covered.
