About Wyoming Exhibit Requirements

Wyoming's 9 judicial districts file through Wyoming Courts eFiling at wyocourts.gov, with exhibit exchange governed by the district court's Scheduling and Case Management Order — keyed to the initial pretrial conference, with a 10-day window to object — rather than by a fixed statewide rule deadline. Laramie County (Cheyenne) and Natrona County (Casper) handle the largest dockets; Campbell County and Sublette County see the heaviest energy litigation.

Court rules and e-filing requirements change frequently. Verify current requirements with your local court clerk or official court website before filing. This content is for general reference only and does not constitute legal advice.

Wyoming Exhibit FAQs

How do I e-file exhibits in Wyoming courts?

Wyoming uses Wyoming Courts eFiling (wyocourts.gov) as the state e-filing system, though availability may vary by judicial district. Check wyocourts.gov to confirm e-filing is available for your specific district. When available, exhibits must be in PDF format with a 150 MB per-transaction limit. Some rural Wyoming districts may still require physical filing.

What are Wyoming's exhibit exchange deadlines?

Wyoming exhibit exchange deadlines are set by the court's scheduling order per W.R.C.P. 16 (Wyoming Rules of Civil Procedure Rule 16), not by a statewide fixed deadline. The scheduling order will specify when exhibit lists must be filed and when exhibits must be exchanged. Each of Wyoming's 9 judicial districts may have variations in local practices.

What exhibit marking system does Wyoming require?

Wyoming courts use the P/D prefix system: plaintiffs mark exhibits as P-1, P-2, P-3, while defendants use D-1, D-2, D-3 per W.R.C.P. 16. This system is standard across all 9 Wyoming judicial districts. Exhibits should be marked before the exchange deadline specified in your scheduling order and listed in your pre-trial order.

Are there special considerations for Laramie County government cases?

Yes. Laramie County (Cheyenne) is Wyoming's state capital and largest county, handling significant government litigation including challenges to state statutes and administrative actions. Government cases often require specialized exhibits such as legislative records and administrative rulings. While exhibit marking follows standard W.R.C.P. 16 rules, government cases may have unique procedural requirements.

Does Wyoming's energy industry affect exhibit procedures?

Yes. Wyoming is a major energy-producing state, and Natrona County (Casper) handles significant oil, gas, and coal litigation. Energy cases often involve specialized exhibits such as mineral rights documents, environmental assessments, and engineering reports requiring expert foundation testimony. Wyoming's vast geography means rural courthouses may have limited resources, so allow extra time for document delivery and travel to remote locations.
