For lawyers who do not have malpractice insurance (legal professional liability), you are required by law in some states to disclose this to clients before engaging with them. Common examples of legal malpractice can include unintentionally failing to maintain communication with clients and not meeting deadlines. A best practice is to ensure your firm against the risk, regardless of state law. Malpractice insurance covers a wide variety of issues and protects your firm in the case of a lawsuit.
