Is malpractice insurance required for attorneys?

The requirement for attorneys to carry malpractice insurance varies by state. As of now, Oregon and Idaho are the only states that mandate malpractice insurance as a condition of practicing law. However, the landscape of disclosure requirements is much broader and continues to evolve.

Approximately half of all U.S. states now require attorneys to disclose their insurance status either to the state bar, to clients, or both. In states like California, Ohio, Pennsylvania, and Virginia, attorneys must inform clients in writing if they do not carry malpractice coverage. Some states require this disclosure in engagement letters, while others mandate it on the state bar's public directory.

Even where coverage is not legally required, there are strong practical reasons to carry it. Many courts require proof of malpractice insurance before approving pro hac vice admissions. Corporate clients and institutional referral sources increasingly demand evidence of coverage before engaging outside counsel. Law firm lease agreements and partnership agreements frequently include insurance requirements as well.

The American Bar Association has long recommended that all practicing attorneys carry malpractice insurance. ABA studies consistently show that approximately 20 to 25 percent of all private practice attorneys operate without coverage, a figure that disproportionately affects solo practitioners and small firms. This gap is concerning because solo and small firm attorneys face claim rates comparable to their larger counterparts but lack the financial reserves to absorb a significant malpractice judgment.

If you are operating without coverage, it is worth understanding the personal financial exposure you face. A single malpractice claim can easily generate $50,000 to $100,000 in defense costs alone, even if the claim is ultimately dismissed. Judgments and settlements can reach well into six or seven figures. Without insurance, those costs come directly from your personal assets in most cases, since professional corporations and LLCs may not fully shield individual attorneys from malpractice liability in all jurisdictions.
