Court opinions are public records, but reading them at scale has historically required a paid subscription. CaseDiver on LawDiver makes 10 million+ opinions searchable at no cost so that anyone — not only firms that can afford Westlaw or Lexis — can find the law that governs their situation. The paid products are the API, MCP server, and bulk data licensing.
No. LawDiver provides court opinions and research tools through CaseDiver. Nothing on the site is legal advice, and it is not a substitute for a lawyer.
