State-by-State Malpractice Insurance Requirements for Lawyers

One of the most common questions attorneys ask is whether they are legally required to carry malpractice insurance. The answer depends on where they practice, and the landscape of state requirements is more nuanced than a simple yes-or-no answer suggests. While only a few states mandate coverage outright, a growing number require disclosure of insurance status, creating a practical imperative that functions much like a mandate.

States That Mandate Malpractice Insurance

As of 2026, only a small number of jurisdictions require attorneys in private practice to carry malpractice insurance. Oregon has maintained a mandatory requirement since 1978, administered through the Professional Liability Fund. Idaho requires coverage for attorneys in private practice. Illinois adopted a mandatory insurance requirement effective in 2024. These states set minimum coverage requirements that all practicing attorneys must meet as a condition of bar membership and licensure.

States That Require Disclosure

A much larger group of states has adopted disclosure requirements, mandating that attorneys report whether they carry malpractice insurance. States including Alaska, California, Colorado, Hawaii, Kansas, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Rhode Island, South Dakota, Virginia, Washington, and West Virginia require some form of insurance status disclosure. In these states, the information is typically made available to the public, creating market pressure on uninsured attorneys who may lose clients to insured competitors.

The Ethical Dimension

Even in states without mandates or disclosure requirements, ethical obligations effectively require many attorneys to consider malpractice coverage. The ABA Model Rules of Professional Conduct require attorneys to provide competent representation and to communicate material information to clients. Many ethics opinions have held that an attorney's lack of malpractice insurance is material information that should be disclosed to clients, particularly at the outset of representation. Failure to disclose can itself become the basis for a disciplinary complaint or malpractice claim.

Minimum Coverage Requirements

States that mandate coverage typically set minimum limits. Oregon's Professional Liability Fund provides $300,000 per claim and $300,000 aggregate coverage, with excess coverage available for purchase. Idaho and Illinois have their own minimum requirements. Firms practicing in mandatory states should understand that minimum limits may be insufficient for their risk profile and should consider purchasing higher limits based on their practice areas, client base, and revenue.

Multistate Practice Considerations

Attorneys licensed in multiple states face the most complex compliance landscape. A firm with attorneys licensed in both a mandatory state and a voluntary state must ensure compliance with the mandatory state's requirements while making informed decisions about coverage in the voluntary state. Multistate policies should be structured to meet the most stringent requirement applicable to any attorney in the firm. Work with a broker who understands the regulatory requirements across all jurisdictions where your attorneys are licensed.

The Trend Toward Mandatory Coverage

The trend in regulation is clearly moving toward greater insurance requirements. Several state bar associations have active committees studying mandatory insurance proposals, and the ABA has issued multiple resolutions encouraging states to adopt either mandates or disclosure requirements. Firms that do not currently carry malpractice insurance should anticipate that requirements in their jurisdiction may change and plan accordingly.

Practical Recommendations

Regardless of your state's requirements, carrying malpractice insurance is a sound business decision. It protects client interests, shields attorney personal assets, enhances professional credibility, and is increasingly expected by clients, referral sources, and courts. If you practice in a mandatory state, ensure you meet or exceed minimum requirements. If you practice in a disclosure state, understand that your insurance status is public information. And if you practice in a state with no current requirements, recognize that the market and ethical landscape still strongly favor insured attorneys.
