CourtListener.com is a non-profit free legal search engine and alert system run by the Free Law Project. Unlike many legal research platforms that hide behind paywalls, this site is upfront about its mission and team. The domain has been active since 2010, which is a strong sign of legitimacy for any online service, especially one dealing with sensitive court records.
What does the data show? Security is well handled: the site uses modern encryption, blocks clickjacking, and has no malware flags. The contact and about pages are easy to find, and the privacy policy and terms of service are clearly posted. For a site that lets you search case law and set up docket alerts, this level of transparency meets what you should expect.
If you are wondering whether CourtListener.com is safe to use for legal research or to install RECAP (their PACER tool), the answer is yes. It is not a scam or a fly-by-night operation. CourtListener.com reviews from legal professionals and power users are overwhelmingly positive. The only minor shortcoming is the lack of DNSSEC, but that is common among reputable sites and not a practical risk for this use case. Overall, this is a trustworthy resource you can rely on.
