The document discusses the ethical and liability risks for lawyers who do not use computer-assisted legal research (CALR) technology such as Westlaw and LexisNexis. While there is no direct rule requiring the use of CALR, the standard of competent legal practice implies that lawyers must use tools that allow for thorough, efficient research. Failure to research issues adequately could lead to ethics violations, malpractice claims, or sanctions. As CALR has become ubiquitous and courts increasingly rely on it, not using these tools risks a lawyer failing to meet the standard of competent legal representation according to evolving practices.
