1. What is the difference between Circuit Court and District Court?
It depends on how long the sentence could be. If the crime can bring more than a year in prison, it is a felony. If not, it is a misdemeanor (W.S. 6-10-101).
- Circuit Court handles all misdemeanors, sets bail and holds the early hearing in felony cases. It also hears small claims and protection orders.
- District Court handles felony cases after that early hearing, plus cases about children. It does not hear traffic tickets or misdemeanors.
- Town courts handle tickets for breaking a town's own rules.
Big Horn County is part of the 5th Judicial District with Hot Springs, Park and Washakie counties. A full-time magistrate serves the circuit court here. Federal crimes go to federal court instead.

↑ Back to the question list4. What happens when someone first goes before a judge?
The first court date takes place in Circuit Court. The person may come into the courtroom or appear on video from the jail. The judge tells them what they are charged with and hands them the written charge. The judge then explains their rights: they may get a lawyer, including a free one if they qualify; they may stay silent; and, if they are in jail, how they might get out (W.R.Cr.P. 5).
For a misdemeanor, the person might enter a plea that day or at a later hearing. For a felony, no plea happens yet; instead, the preliminary hearing gets scheduled and release is decided. Anyone arrested without a warrant must be let go if a judge does not find a good reason for the arrest within 72 hours.
↑ Back to the question list5. How are misdemeanors like battery or theft handled?
Misdemeanor cases begin and end in Circuit Court. The person enters a plea, and then the case is settled by a deal, a trial or a dismissal. A jury trial is possible if the person asks for one. The pleas Wyoming allows are not guilty, not guilty by reason of mental illness, guilty, and no contest with the judge's OK (W.R.Cr.P. 11).
Top penalties for charges that come up often:
- A misdemeanor with no penalty of its own: up to 6 months in jail and a $750 fine (W.S. 6-10-103).
- Battery: up to 6 months and $750. Simple assault, where no one is hurt, carries a fine up to $750 (W.S. 6-2-501).
- Domestic battery, first time: up to 6 months and $750. A second within five years raises the top to 1 year and $1,000 (W.S. 6-2-511).
- Theft under $1,000, shoplifting included: up to 1 year and $1,500 since July 1, 2026 (W.S. 6-3-402).
Most cases also pick up two add-on charges: $40 for court computer systems and $10 for legal help programs.
↑ Back to the question list6. What are the steps in a Big Horn County felony case?
- First court date in Circuit Court. Bail and a lawyer are decided.
- Preliminary hearing in Circuit Court, within 10 days for someone in jail or 20 days for someone released. The judge decides if there is enough evidence. If there isn't, the case is thrown out. The defense can give up this hearing (W.R.Cr.P. 5(c) and 5.1).
- Arraignment at the District Court, where the plea is made.
- Trial within 180 days after arraignment, unless the court allows a delay (W.R.Cr.P. 48(b)).
- Sentencing, which must happen face to face, not by video.
Felony penalties differ by crime. Someone convicted of burglary can get as long as 10 years, plus a fine as large as $10,000 (W.S. 6-3-301). Theft of property worth $1,000 or more carries up to 10 years, and so does stealing a gun, a horse or livestock. A third theft, no matter how small, has been a felony since July 1, 2026 (W.S. 6-3-402).
↑ Back to the question list7. What happens with violent felony charges?
The possible prison time climbs fast. Aggravated assault, such as hurting someone with a weapon, can mean up to 10 years, and some forms mean 5 to 25 years (W.S. 6-2-502). Aggravated burglary, where someone is armed or gets hurt, means 5 to 25 years and up to a $50,000 fine (W.S. 6-3-301(c)). A domestic battery with two earlier ones in the past ten years becomes a felony with up to 10 years.
The judge sets release terms for each person. Bail can be denied only in a death-penalty case where the proof is evident (Wyo. Const. art. 1, sec. 14). A teen of 14 charged with a violent felony may be tried in adult court. With charges this serious, getting a lawyer right away matters a lot.
↑ Back to the question list8. Who are the lawyers on each side?
The Big Horn County & Prosecuting Attorney brings state charges, both misdemeanors and felonies. Write to P.O. Box 647, Basin, WY 82410, or call 307-568-2436.
A person who can't pay a lawyer can ask for one from the Wyoming State Public Defender. Its Administration Office is at 316 West 22nd Street, Cheyenne, WY 82002, 307-777-7519. The judge decides who qualifies by looking at money and income. Anyone with income below 125% of the federal poverty line qualifies, and people on aid like Medicaid or SSI are presumed to (W.S. 7-6-106). The best time to ask is the first court date.
↑ Back to the question list9. How do I find a court date in Big Horn County?
Call the clerk with the person's full legal name and birthday:
- Misdemeanors and first felony steps: Circuit Court, 307-568-2367.
- Felony cases once they reach District Court: the clerk, 307-568-2381.
- Town tickets: the town court listed above.
District Court case files can be looked up at the clerk's office. The date of the next hearing is also printed on the release papers. If a case is appealed to the Wyoming Supreme Court, you can follow it in the Supreme Court case search.
↑ Back to the question list10. Is there a warrant, and how is it cleared?
The Big Horn County Sheriff's Office serves warrants here. Call 307-568-2324, which is answered all day and night, to ask if one is out. Wyoming has no statewide warrant search, so a phone call to the sheriff is the way to know. If the warrant allows a bond, contact whoever issued it, which may be Basin Municipal Court, the Greybull Police Department, or the county's Circuit or District Court. To clear any other warrant, work with a lawyer and turn yourself in at the jail, 415 Murphy St., Basin, WY 82410, or ask the clerk for a new court date. Circuit Court: 420 West C Street, Basin, WY 82410, 307-568-2367.
↑ Back to the question list11. How is a federal case different?
Federal cases go to the U.S. District Court for the District of Wyoming. The main office is the Joseph C. O'Mahoney Federal Center, 2120 Capitol Avenue, Room 2131, Cheyenne, WY 82001, 307-433-2120. Hearings may also be held at the Casper office in the Ewing T. Kerr Federal Building, 111 South Wolcott, Room 121, Casper, WY 82601, 307-232-2620.
At the start, a judge holds a hearing on whether the person stays locked up before trial (18 U.S.C. 3142). U.S. Probation and Pretrial Services in Casper, 111 South Wolcott, Room 300, Casper, WY 82601, 307-232-2670, gives the judge information. The U.S. Marshals in Casper, 111 South Wolcott, Room 138, Casper, WY 82601, 307-261-5411, keep people before trial. The Basin jail rents beds to the Marshals for Wyoming and Montana. To read federal filings, use the court's electronic filing site; it needs a PACER account. After sentencing, try the BOP inmate locator.
↑ Back to the question list12. What does an ICE hold mean for the case?
An ICE hold does not stop the criminal case. It does change what happens at release:
- ICE, the immigration agency, files Form I-247A with the jail to ask for notice and a hold.
- Federal rules let the jail hold the person up to 48 hours after they would otherwise be released (8 CFR 287.7(d)). That is true even if the case is dropped or bail is posted.
- ICE then takes custody and moves the person to a center it chooses.
- Search for them on the ICE detainee locator. Enter an A-number, or a name and birth country.
ICE's Casper check-in office serves this county: 150 E. B Street, Room 1014, Casper, WY 82601, 307-261-6590. Since 2025, Wyoming law forbids local limits on working with immigration officers (W.S. 9-25-102). A guilty plea can hurt a person's immigration case, so anyone who is not a citizen should talk with their lawyer first.
↑ Back to the question list13. Where are Big Horn County sentences served?
Jail time for a misdemeanor is done in Basin at the county jail. A felony prison sentence puts the person in the hands of the Wyoming Department of Corrections. It first studies each new prisoner to set a security level, then places them in a matching prison.
The state offender locator finds people by WDOC number or by the start of their last name. It covers prison, probation and parole. You can see all of the state's prisons on our Wyoming prisons page. Corrections headquarters is at 1934 Wyott Drive, Suite 100, Cheyenne, WY 82002, 307-777-7208.
↑ Back to the question list14. How are cases against minors handled?
Cases where a child is accused of a crime are heard in District Court, 420 West C Street, Basin, WY 82410, 307-568-2381. The records are private, and the hearings are closed unless someone asks for a jury trial.
Wyoming law draws the lines (W.S. 14-6-203). Children younger than 13 who face a felony charge remain in juvenile court. Adult court is possible for a 17-year-old facing any felony, or a 14-year-old facing a violent one. A judge can move a case from one court to the other after looking at the crime, the child's maturity and their record (W.S. 14-6-237). Smaller offenses by minors can be filed in Circuit Court or a town court. A youth who has to stay locked up is sent to a youth detention center, such as the Campbell County Juvenile Detention Center, 600 West Boxelder Road, Gillette, WY 82718, 307-687-6138, where they are kept away from adults.
↑ Back to the question list15. What help is there for crime victims in Big Horn County?
Wyoming's Victim and Witness Bill of Rights protects victims (W.S. 1-40-201 to 1-40-210). Victims have the right to:
- Learn when the accused is released before trial or sentencing.
- Be in court whenever the accused is, unless a judge has good cause to say otherwise.
- Speak or write to the judge about how the crime affected them before sentencing.
C.A.R.E.S. runs the local victim and witness program and helps with domestic violence and sexual assault. Its Basin office is at 420 West "C" St., Basin, WY 82410, 307-568-3334. Its Lovell office is at 355 E. 5th St., Lovell, WY 82431, 307-548-2330. The toll-free crisis line is 888-372-3334. Statewide, the Division of Victim Services is at 320 West 25th St., 2nd Floor, Cheyenne, WY 82002, 307-777-7200. Free custody alerts are available through VINE or at 866-994-8463.

Big Horn County Wyoming Criminal Court System – Definitions
It might be helpful to define some words that will be used on this site, when explaining the Wyoming Court System and how it works. The definitions on this site are for general information and not legal advice. It is always preferred to follow information given by your attorney or local authorities.
If you scroll down below this content, and the listing of the courts in Big Horn County, you will find a simple flowchart diagram and a video that will help you visualize the stages of the Criminal Court Process.
Arrest is when Wyoming, Big Horn County or local police take a person into custody and start the legal process. The arrested person may or may not be immediately jailed.
In less serious crimes, the person may only be given a citation ordering that they appear in municipal or Big Horn County court on a certain date. In cases involving more serious crimes, the person is usually placed in the county jail until an arraignment, or a judge decides the next step.
Booking is when the Big Horn County sheriff or local police gather information such as the detainee’s name, address and why the person is being arrested. Booking also includes fingerprinting, criminal history, investigation, and verification of identity. Bail for lower-level crimes may be set right after booking so the arrested can “bail or bond out” before being detained.
The prosecution, sometimes called “the government” or “the people” or “the state” is the side that presses the charges and seeks punishment for the offense. These are attorneys that work for the state of Wyoming, Big Horn County or a city or town. The prosecuting attorney for Big Horn County or the district is called the Deputy County Attorney or Deputy Prosecuting Attorney. A U.S. Attorney prosecutes federal cases.
Jurisdiction is an important term in the court system that means whether a court has the obligation or duty or right to handle a case. For example, if you run a red light in your town or city, a municipal court would likely have jurisdiction over your case, but the next town or city over would not have jurisdiction over your case. If you attempted to flee from police when they attempted to stop you after you ran the red light, it becomes a more serious crime, and the municipal court might not have jurisdiction so you might be assigned to a higher-level court that has jurisdiction over the more serious crime. Jurisdiction varies from state to state and sometimes county to county.
Arraignment is when a judge determines whether the charges are supported by the prosecution’s initial evidence and tells the arrested what they are charged with, and the person says whether they are guilty or not guilty. At this time, the person is called the defendant, and the opposing side is called the prosecution. If there is reason to believe that the arrested is guilty, the judge will set bail conditions or send the defendant to jail or release them ROR (release on recognizances). An arraignment is not a trial, and the defendant is entitled to a trial within a reasonable amount of time after the arraignment.
Bail is money paid that is held by the Big Horn County or municipal court to make sure that the arrested does not flee the area before their trial. Bail amounts and other conditions are determined at the arraignment. Once the case is over, the bail money is returned to the defendant. If a person does not pay bail, they remain in the Big Horn County Jail until their trial.
Bail can be denied if the court feels that the arrested would be a danger to others if released. Sometimes the court decides that there is a good chance that the arrested will show up for trial and not flee so they are released on their own promise, or recognizance without having to pay bail.
A bond proceeding is the determination of how much bail is to be paid and usually happens at the same time as an arraignment. During bond proceedings, the defendant can have an attorney present but does not have the right to an attorney. A judge or court officer in the {county extended} or municipal court sets bail. Judges in Wyoming rely on a statewide bail schedule, which sets out a recommended range of bail amounts for different offenses. Judges can still exercise discretion in setting bail above or below the recommended range.
A judicial public bond or personal recognizance bond is a bond where someone representing the defendant signs paperwork promising to pay the money if the defendant does not show up to court. If the defendant does not show, the full amount will be due and the people who signed the paperwork will be responsible for paying the court. Sometimes the court decides that there is a good chance that the arrested will show up for trial and not flee so they are released on their own promise, or recognizance.
Cash percentage in lieu of bonds. If the bond order permits, the defendant pays a percentage of the amount, (usually 10%) to the court, which then holds the money until the case is over. The amount is returned if the defendant is acquitted or the case is dismissed, or it can be used toward paying any court fines incurred by the defendant.
Surety Bond is when defendant pays a percentage of the bond amount (usually 10–15%) to a professional bondsman or bail bond company licensed to do business in Wyoming, {county extended}. The bondsman then signs the bond on behalf of the defendant. The defendant does not receive any of the money back. If the bondsman feels the defendant is a flight risk, they can refuse to give a bond or charge a higher fee. For example, a bondsman may determine a defendant is a flight risk if they are from a state other than Wyoming.
A Property Bond is a bond in which the bond is pledged in land or home real estate (mobile homes are not accepted). Usually, the property must be in Big Horn County, and it must be worth at least 1 ½-2 times the amount of the bond.
It is always important to have family involvement after being arrested. Not only can they make calls and communicate on your behalf (not all bond companies will accept collect calls), but family support will show the court that there are people who will make sure that the defendant makes it to court, not only for the defendant’s own good, but because they may have signed bond paperwork and responsible to pay if the defendant does not show in court. Chances of obtaining a bond from a bond company or clerk of court are better if family is involved.
(There have been phone scams where a bond company calls and informs a person that their family member has been arrested and they ask for financial information. A bondsman will not call asking for money without involvement of the arrested.)
A criminal defense attorney (also called lawyer or counsel) is hired or retained to represent the arrested as early as possible after the arrest.
If there is a chance that the case might go to trial and the defendant cannot afford an attorney, the 6th Amendment of the U.S. Constitution requires that the court provide an attorney. This is called indigent representation and a public defender or assigned attorney would represent the defendant in all proceedings. Indigent representation is only available misdemeanor and felony cases that could result in jail time, juvenile cases, and certain appeal cases.
In Wyoming, 85% of funding for indigent services comes from the state and 15% from county and local resources. Wyoming does not appoint attorneys like other states.
For less serious cases or civil cases, there are pro bono volunteers who volunteer legal services for free or for a small fee. They often will hold clinics to teach people how to represent themselves in court or expunge their record which means to legally erase or eliminate a criminal or arrest record from public view.
This website provides contact information for pro bono services in Wyoming.
Many courts will provide forms and help for people who want to represent themselves, called pro se. This is a site offered by the Wyoming State Courts to assist in legal self-help.
A district court can refer to the first level of the legal system, or a minor court. District courts are in the community. A district court can also refer to a U.S. Federal District Court that hears federal cases. There is one U.S. federal district court in Wyoming, with offices throughout the state. It is important that you check the address of the court you are to appear in rather than to ask someone because that person might give you directions to the wrong “district” court. Being late to court can land you in custody as well.
Pretrial proceeding is the process where both sides (prosecution and defense) gather information, interview witnesses, request records, videos etc. Pretrial proceedings also include communications with the judge assigned to the case and these appearances are either in person or by on-line conferencing. Some pretrial proceedings may not require a defendant’s appearance, allowing an attorney to appear in their place. The information that is gathered is called discovery and both sides must share the information that they have gathered. This information does not include conversations between the arrested and their attorney.
Most cases do not go to trial because both sides reach a plea deal, where both sides try to reach a reasonable punishment based on what was learned in the pretrial proceedings. A plea deal can only happen if the accused person admits they are guilty in exchange for a lighter punishment. The reason they must admit guilt is because it would not be fair to punish someone who claims they are not guilty. There are times in plea bargaining when the prosecution agrees to give a lighter sentence in exchange for information leading to the arrest of a more serious criminal related to the crime.
Trial is where both sides share their information in front of a judge or a judge and jury. After listening to all the evidence, the judge or jury decides the verdict which is whether the person is guilty or not guilty. If a court has only a judge hearing both sides, it is called a bench trial. If a jury is selected, it is called a jury trial. If the defendant is found not guilty, they are released. If they are found to be guilty, the next step is sentencing.
Sentencing is the punishment that the judge decides the person should get. This could be jail or prison time, fines, community service, probation, or a combination.
Appeal is asking for a higher court to hear the case again at an appellate court. If the accused person thinks something went wrong at trial or has new information that was not available during the trial or that the sentence is too harsh, the defense attorney can ask for an appeal. It is not unusual for an appeal when there is a long jail sentence, but an appeal can be denied if the appellate court feels that the original trial or sentencing was fair.
The Big Horn County Clerk of Court is an elected official whose responsibilities for Criminal Court’s administrative issues include receiving criminal warrants, receiving bail, creating the trial schedule, receiving fees, fines and maintaining court records.
A warrant is used to get someone to appear in court or to law enforcement. There must be good reason to believe that the person is involved in a crime. The warrant gives authority to arrest the person and search for evidence for the investigation of the crime.
A criminal summons is issued to request that a person appear in court at a particular time and date. It does not involve an arrest. A traffic ticket, summary citation or lesser misdemeanor could be considered a summons if you are given a court date.
A summary citation, commonly referred to as a ticket, is a criminal summons by a law enforcement officer either in person or via mail accusing the defendant of a minor offense, stating potential fine, listing the court having jurisdiction and instructions for addressing the issue. Defendants may or may not be required to appear in court or handle the matter by entering a plea via mail.
Fines are usually paid to the District Court or clerk of court and payment methods can be found on the District Court or Big Horn County Clerk of Court website. If you do not pay your fine on time, you can lose your driver’s license, must pay additional fees or even have a warrant for your arrest. It is important to read the instructions on the ticket issued by the police officer or court at the time of your arrest. For a parking ticket or summary citation, the fine amount and how to send payment should be on the ticket.
Wyoming Criminal Court System - How it Works
Wyoming Municipal Courts handle violations of municipal ordinances (city laws), traffic violations, parking violations and criminal misdemeanor offenses that occur within the city or towns police jurisdiction. A municipal court judge in Wyoming can sentence jail time of up to 6 months in jail and/or $750. Not all areas have municipal courts in which case the circuit court would have jurisdiction.
Wyoming Circuit Courts handle all misdemeanor cases and can conduct preliminary hearings for felony cases to be further prosecuted in district court. There is a district court in every county.
Wyoming District Courts handle criminal felony and juvenile cases from beginning to end. There is a district court in every county.
Specialty courts or problem-solving courts are being adopted in many states as a way to handle cases that involve non-violent and first-time offender cases in a way to where the offender can retain a job or responsibilities while following specific orders of the court as returned court appearances, periodic evaluations or testing for substances. Wyoming works with the Department of Health to provide Court Supervised Treatment Programs. Find out more at the following link.
Wyoming does not have an Intermediate Court of Appeals like many states.
The Wyoming Supreme Court is like our United States’ Supreme Court because it has a panel of judges that rule on matters that have to do with someone’s constitutional rights or policies and laws. The Wyoming State Supreme Court deals with the state constitution or laws or policies. Sometimes the Supreme Court will hear criminal cases on appeal when there is a question on the state laws or procedures that lead to the appeal.
The criminal cases are usually referred from the circuit courts and district courts.
FEDERAL COURT
Federal Court deals with crimes involving violations of United States laws. Federal crimes include federal drug trafficking, federal tax evasion and fraud that crossed state lines and include crimes that occur on federal property as post offices or federal buildings.
Cases involving crimes that involve the FBI or DEA or Immigration agencies are federal crimes. Terrorism is a federal crime.
There are some differences in the Federal court system as compared to the Wyoming state court system. For example, the attorneys who work for the courts are called United States Attorneys and Federal judges are called District Court Judges (not to be confused by local state district courts).
Federal Magistrate Judges hear the case early on, but they do not decide on the cases at a trial like the Federal District Court Judges. In a federal case, a grand jury is used for indictments.
There is one U.S. Federal Judicial District in Wyoming.
