Trellis

Trellis gives you a window into state trial courts, providing access to millions of searchable court documents, dockets, and judicial rulings. Instead of guessing how a judge might rule, you can analyze their past decisions and track how similar cases have performed in specific jurisdictions. This helps you move beyond high-level legal theory into the practical reality of how local courts operate daily.

You can use the platform to research opposing counsel, vet expert witnesses, and monitor new litigation filings in real-time. By surfacing data that was previously trapped in fragmented county systems, Trellis allows you to draft more persuasive motions and make data-driven decisions about whether to settle or head to trial. It is designed primarily for litigators, paralegals, and legal researchers at firms of all sizes.
