Quick answers
Frequently asked questions
1Is LII Cornell truly free, or are there hidden subscription tiers for full access?⌄
LII Cornell is entirely free and open access. There are no subscription tiers, paywalls, or premium features. All content, including federal and state statutes, Supreme Court opinions, and the Wex legal encyclopedia, is available to everyone without charge, upholding its public service mission.
2How frequently is the legal content updated, especially for rapidly changing statutory or regulatory areas?⌄
LII strives to keep its primary legal materials current. Federal statutes (U.S. Code) and the Code of Federal Regulations are updated regularly, typically within weeks of official publication. State statutes are updated as frequently as resources allow, often annually or biannually, depending on the state's legislative cycle. Supreme Court opinions are posted shortly after release.
3Can I rely on LII Cornell for official legal advice or as a substitute for a legal professional?⌄
No, LII Cornell provides legal information for educational and research purposes only. It does not offer legal advice, and using the site does not create an attorney-client relationship. For specific legal issues, always consult with a qualified attorney in your jurisdiction.
4How does LII Cornell compare to commercial legal research platforms like Westlaw or LexisNexis?⌄
LII Cornell provides foundational primary legal materials and explanatory content for free, making it an excellent starting point for many. Commercial platforms offer more advanced features like sophisticated citators, extensive secondary sources, practice guides, and specialized databases, which come at a significant cost. LII is ideal for basic research and understanding, while commercial platforms cater to in-depth professional legal practice.
5Is there a way to contribute to LII Cornell or support its mission?⌄
Yes, as a non-profit organization, LII Cornell relies on donations to maintain and expand its services. You can find information on how to support LII through financial contributions on their website, typically via a 'Donate' or 'Support Us' link, to help sustain its free access to legal information.
