Oklahoma does not split crimes between a lower and an upper trial court. One District Court per judicial district hears it all, and this county belongs to District 20. That court's reach covers "all justiciable matters" (Okla. Const. art. VII § 7).

• Felonies, the charges that carry possible prison time, stay in District Court from filing to sentence.
• State misdemeanors, punished by county jail or fines, are filed in that same court.
• City tickets from Davis or Sulphur officers go to that city's municipal court. By the state Constitution, a city court handles only traffic and criminal cases (Okla. Const. art. VII § 1).

Special Judges sit on it, and so do Associate District Judges and District Judges (Okla. Const. art. VII § 8). The first two kinds win their seats in nonpartisan elections.

• County courthouse, where you find the District Court, its clerk and the prosecutor's local office: 1001 W. Wyandotte Ave., Sulphur, OK 73086. The clerk's window keeps normal weekday business hours. For the clerk's direct line, the Sheriff's Office at 580-622-5106 can steer you.
• Courthouse annex: 1019 W. Wyandotte Ave., Sulphur, OK 73086, next door to the main building.
• Davis Municipal Court: Thursday sessions in the City Council Chambers, 308 S. 3rd Street, Davis, OK 73030. Enter on the west side, by the porch near the play equipment.
• Davis court clerk: the utility payment counter at City Hall, 227 E. Main St., Davis, OK 73030, 580-369-3333, open Monday through Friday from 8:00 a.m. to 5:00 p.m.
• Sulphur City Hall, where city court fines are paid: 600 W. Broadway Ave., Sulphur, OK 73086, 580-622-5096, weekdays 8:00 a.m. to 4:30 p.m.

Four towns sit inside the county lines. Their tickets go to different places:

• Davis calls its city docket each Thursday at 308 S. 3rd Street, Davis, OK 73030. The clerk is at City Hall, 227 E. Main St., Davis, OK 73030, 580-369-3333. Ticket payment choices are listed on the city's municipal court page.
• Sulphur employs a court clerk and takes city fines at City Hall, 600 W. Broadway Ave., Sulphur, OK 73086, 580-622-5096. Ask there for the court's meeting day and room.
• Dougherty and Hickory are very small. For a charge filed in either town, the Sheriff's Office at 580-622-5106 can tell you which court took it.

Davis straddles the line with Garvin County. A state charge from the Garvin side may be filed in that county's court.

For a person sitting in jail, the opening hearing tends to come quickly, though weekends can stretch the wait. Video is allowed under SB 1711 if the jail holding the person is in some other county. Expect these pieces:

• the charges are read
• the person learns a lawyer can be appointed if they can't pay
• bond gets set, kept or changed
• a return date is handed out

A felony arraignment in District Court skips the plea for now. Jot down every date and courtroom the judge mentions, since a missed date brings a warrant.

State misdemeanors are filed by the District Attorney in District Court. Most go roughly this way:

1. The charge is filed, and the person comes before the judge.
2. The person enters a plea. Plenty of cases end in a deal, with fines, classes or probation.
3. Someone who wants a trial can have a jury, and a District Court misdemeanor jury seats six.

Charges people see a lot:

• Holding drugs for your own use was cut to a misdemeanor in July 2017 by State Question 780.
• Taking goods valued under $1,000 dropped to a misdemeanor under that same vote.
• DUI is usually a misdemeanor the first time. On a second arrest, nobody walks out until a judge fixes bail (HB 1222).

Penalties hinge on the exact count, so ask the defense lawyer for the range that applies.

A felony takes more stops in District Court:

1. Arraignment. The formal charges are read. Pleas wait for later.
2. Preliminary hearing. This is a check on the evidence, not a trial. Here the prosecutor must persuade the judge on two points. First, the crime occurred within this county. Second, the evidence gives probable cause against the accused.
3. Trial or plea deal. Twelve jurors decide a felony trial.
4. Sentence. Punishment comes from the judge or the jury.

Slow cases get flagged for review under SB 325, passed in 2024. The first mark comes at 9 months, counted from the first appearance, if the person is jailed on that charge alone. A defendant who is out of jail gets 18 months before that review.

Crimes committed from January 1, 2026 on fall into 14 lettered felony classes. At the heavy end sit Y and A1, while D2 and D3 sit at the light end (HB 1792; HB 2104 and HB 2105 then reworked it). Each written judgment now names the class plus the shortest time the person must serve. Time served before trial almost always counts toward the sentence.

A violent charge raises the stakes in four ways:

• Bail can be refused. For a violent offense, a judge may hold someone without bail after deciding the evidence is solid and that release terms could not keep others safe (Okla. Const. art. II § 8).
• A second violent arrest on bond. Release then starts out disfavored (HB 3782).
• Top classes. Under the new class system, violent crimes are grouped into Y, A and B.
• The 85% rule. On certain crimes, the parole board won't consider release until 85% of the sentence is done (21 O.S. § 13.1).

Armed robbery, child abuse, and murder, rape or burglary in the first degree all appear on that 85% list. With stakes like these, hire or request counsel on the first day.

Prosecutor. District 20's elected District Attorney handles this county along with Carter, Johnston, Love and Marshall. The local branch works from the courthouse, 1001 W. Wyandotte Ave., Sulphur, OK 73086, 580-622-5417. Headquarters is Carter County Annex #1, 107 1st Ave. SW, Ardmore, OK 73401, 580-223-9674.

Defense. To get a lawyer the state pays for, the person fills out an application filed with the Court Clerk. From jail, a detention officer can hand over the paper. Who qualifies is up to the judge (22 O.S. § 1355A). A $40 Court Fund fee comes with it, and paying can be put off to the end.

Oklahoma court records sit on two statewide websites. Search each one with the last name first:

• the OSCN court records search
• the ODCR district court records site

Once you spot the case, save its case number, because every office asks for it. Still nothing? Stop by the Court Clerk at 1001 W. Wyandotte Ave., Sulphur, OK 73086, or have the Sheriff's Office at 580-622-5106 read you the next date.

For a Davis ticket, the city clerk at 580-369-3333 knows which Thursday it is set for.

Sheriff's deputies carry out county warrants. Phone them at 580-622-5106 to ask whether one exists, or search open cases on OSCN and ODCR. Statewide, fugitives appear on the Attorney General's 10 Most Wanted, escape notices the DOC posts as Orange Alerts, and the federal Marshals Service top fugitives. To get a warrant cleared, call a lawyer first. Then go together to the jail, 700 W. 10th St., Sulphur, OK 73086, or ask the judge's office that signed it about a bond or a fresh court date. That office, the Court Clerk, sits at 1001 W. Wyandotte Ave., Sulphur, OK 73086.

This county falls under the Eastern District of Oklahoma. Its clerk works at 101 N. 5th Street, Room 208, Muskogee, OK 74401, 918-684-7920, from 8:30 a.m. to 4:30 p.m. on weekdays.

1. A federal magistrate or judge weighs flight risk and danger at a detention hearing, then rules on release (18 U.S.C. 3142).
2. Anyone held is in Marshals custody, often at the Federal Transfer Center, 7410 S. MacArthur Blvd, Oklahoma City, OK 73169, 405-682-4075, or in a county jail paid by the Marshals to hold federal prisoners. Call the Muskogee Marshals office at 539-239-5500 to learn where.
3. The U.S. Attorney brings the case from 520 Denison Ave, Muskogee, OK 74401, 918-684-5100.
4. If money is short, ask for the Federal Public Defender, 112 N. 7th Street, Muskogee, OK 74401, 918-687-2430.
5. Following a sentence, search the Federal Bureau of Prisons inmate locator.

Sometimes. McGirt v. Oklahoma (2020) started it, and the Court of Criminal Appeals later held that the Chickasaw reservation was never ended by Congress and so remains in place. For a tribal citizen charged over conduct in Indian country, that usually moves the case out of state court. Smaller matters go to tribal court. Major crimes go federal.

Oklahoma v. Castro-Huerta (2022) cut the other way for non-Indians. Picture a non-Indian defendant, an Indian victim, and a crime scene in Indian country. In that setup, either the state or the federal government may bring the case.

Court rulings on this keep shifting. A defense lawyer is the right person to sort out which court fits.

Yes. Even after a judge grants release, an ICE hold can keep the person inside:

1. Jail staff receive an ICE request to hold, known as Form I-247A, and act on it.
2. Staff may hold the person up to 48 hours after they would otherwise be released (8 CFR 287.7(d)).
3. ICE comes for the person inside that time.
4. One common destination is the Cimarron Correctional Facility, 3200 S. Kings Hwy., Cushing, OK 74023, 918-225-3336. ICE also keeps an office at 1220 Sovereign Row, Oklahoma City, OK 73108, 405-219-3199, run under its Dallas Field Office.
5. Track the person on the ICE Online Detainee Locator.

A plea deal can hurt a noncitizen's legal status. Tell the lawyer about citizenship early. Oklahoma's own immigration crime, HB 4156 (21 O.S. § 1795), stays on ice under a federal court order while the state appeals.

State prison terms are run by the Oklahoma Department of Corrections. The path tends to look like this:

1. Sentencing comes, and then a long wait in the county jail. Per DOC, half a year to nine months is the norm.
2. DOC picks the person up for an assessment and reception center, where they are classified.
3. A prison that matches the custody score comes after that.

The DOC Offender Lookup shows where someone is, and our Oklahoma prisons directory covers each site. For a person already inside DOC, the case manager answers family questions.

Youth cases here are handled by the Office of Juvenile Affairs, 921 W. 11th, Suite 2B, Sulphur, OK 73086, 580-622-4410. If a teen must be held, it happens in a juvenile detention center, apart from the county jail.

• A teen who is held must see a judge soon. In most cases that is by the next court day. Transport trouble or another good reason can stretch it by one more court day.
• The Youthful Offender Act carves out its own track for older teens, 15 through 17, who face grave charges.
• Certification lets a judge send a teen's case up to adult court. The opposite move, called reverse certification, hands an adult case back to the youth side.
• A finding of delinquency leads to probation or OJA custody.

Marsy's Law sits in the state Constitution (Okla. Const. art. II § 34). It promises victims respect and privacy. They can speak at hearings on release, pleas and sentences. Restitution must be paid in full, and delays should be kept short.

• Case updates come by request. Put it in writing to the District Attorney. Name the accused, then add the county and the case number. Add a mailing address and a phone number for yourself. Mail it to 1001 W. Wyandotte Ave., Sulphur, OK 73086, or call 580-622-5417.
• The district's victim-witness staff take calls at 580-221-5536.
• A state fund for victims can pick up costs like doctor bills, therapy, missed wages or burial. Ask at 405-264-5006.
