What is Court Rules?
Court Rules is a free reference for U.S. federal court practice, covering the Federal Rules of Civil Procedure alongside district local rules, individual judge standing orders, and court holidays — all organized by court. Instead of hunting through scattered PDFs and court pages, you can search a judge, a court, or a rule topic and get the rule you need, with every rule linking back to the court's own document so you can verify it before filing. There's no sign-up required, and the same underlying data is also exposed through a public API and an MCP server at courtrules.app/mcp for legal-tech tools and AI assistants.
Who it's for
- Litigators and legal teams — who need page limits, courtesy copy rules, and pre-motion requirements before a filing deadline.
- Paralegals and court staff — tracking court holidays, court days, and business-day calculations across districts.
- Legal-tech builders — who want the same rules data piped into their own tools via the API or MCP server.
Key features
Deadline and court-day calculators
Count calendar, business, and court days toward a filing deadline, with federal and state court holidays applied. Separate calculators cover federal deadlines and court days between two dates for any court.
Judge standing orders and individual practices
Individual practices from judges across districts — including the Southern District of New York, Eastern District of New York, Central District of California, Northern District of California, Northern District of Illinois, and District of New Jersey — are collected and searchable.
Rules by topic across courts
The same rule is compared across every court and judge, covering page and word limits, courtesy copy requirements, pre-motion conference requirements, document format requirements, sealing and redaction procedures, and electronic filing rules.
MCP server and REST API
The same rules data is available to your own tools and AI assistants through an MCP server and a REST API. Notes on how the rules are built are published on the Court Rules blog.
What stands out
Every rule links to the court's own document, so you can check it before you file.
That verification-first approach is what separates Court Rules from a plain rules digest — you're never left trusting a summary with no source. The breadth is notable too: federal courts by circuit, state courts by state, and judge-level standing orders all live in one searchable place. And because the data is served through both an API and an MCP server, it's built to plug into legal-tech workflows rather than stay a standalone reference.
Worth checking out if…
You practice in federal or state courts and want a faster way to confirm local rules, judge-specific requirements, and filing deadlines. It's also worth a look if you're building legal-tech tools and need structured court rules data, or if you simply need reliable court holiday calendars for deadline calculations.
