South Dakota has a single court system split into seven circuits, and Deuel is part of the Third. Inside the Clear Lake courthouse, two levels of court share the space:

• Magistrate court may try any misdemeanor or local ordinance case (SDCL 16-12B-11). Magistrate judges issue warrants too, set bond, and handle first appearances (SDCL 16-12B-5, 16-12B-7, 16-12B-10). Guilty pleas on charges worth up to one year or $2,000 can be taken there (SDCL 16-12B-8).
• Circuit court owns the felonies. A Deuel felony begins in magistrate court, then climbs to circuit court, where it is tried or settled by plea.

Circuit court hears youth cases too. Federal crimes are tried in Aberdeen.

Deuel has one courthouse for state criminal cases:

• Deuel County Courthouse, Clerk of Courts, 408 4th Street West, Clear Lake, SD 57226, 605-874-2120. Letters go to PO Box 308, Clear Lake, SD 57226-0308. Clerk hours are 8 a.m. to noon and 1 to 5 p.m. on weekdays. The building shuts for weekends plus state and federal holidays. Deputies keep their office on the first floor.
• Court Services (probation), 314 Sixth Avenue, Suite 6, Brookings, SD 57006, 605-688-4208. Deuel probationers report to officers based here.

Forms and links sit on the court system's Deuel page. Deuel itself runs no treatment court, so ask a defense lawyer whether a drug or DUI program elsewhere in the circuit could accept the case. For questions about these programs, phone the state's Division of Treatment Courts at 605-773-4161.

They don't. A town ordinance ticket in Deuel is heard by magistrate court (SDCL 16-12B-11), which meets at the courthouse, 408 4th Street West, Clear Lake, SD 57226.

Whether the stop was on a town street or a gravel road, the file ends up with the same clerk. Ask for it by the person's name and birth date at 605-874-2120.

The officer must take the arrested person to the nearest magistrate "without unnecessary delay" (SDCL 23A-4-1). Video is allowed. So a Deuel defendant may see the judge on a screen at the Brookings or Watertown jail.

No plea is taken at this hearing. The judge covers five things (SDCL 23A-4-3):

• the charge, read out;
• the right to hire counsel, or to request appointed counsel when money is short;
• bond or the release terms;
• the right to stay quiet;
• in a felony case, a preliminary hearing if they want one.

Third Circuit rules add a deadline. For anyone kept in custody, probable cause must be found by a judge within 48 hours. Otherwise, the jail must release them.

A Deuel misdemeanor usually stays in magistrate court start to finish. The defendant pleads guilty, or pleads not guilty and gets a trial date. First and second DUIs fall under Class 1, as does simple assault.

• Class 1: up to a year of county jail time and a $2,000 fine (SDCL 22-6-2).
• Class 2: up to 30 days of county jail time and a $500 fine.
• Petty offense: a $25 judgment and no court costs under the state fine schedule.

Probation can include the state's 24/7 Sobriety Program when a judge orders it (SDCL 1-11-21). Because Deuel has no lockup, jail time lands in a contract jail. Deuel fines and costs can go on a card at UJS ePayments.

Felonies open in magistrate court, then shift up to circuit court. Most follow this path:

1. First appearance. The charge is read, counsel is hired or appointed, and bond is set.
2. Preliminary hearing. Is there enough proof to go on? A judge decides. For a jailed defendant it comes within 15 days of the first appearance, and within 45 for one who is out. A waiver or an indictment skips it (SDCL 23A-4-3).
3. Formal charge. Most Deuel felonies proceed on an "information" written by the State's Attorney. Grand juries are rare. They meet only when a circuit judge summons 6 to 10 citizens (SDCL 23A-5-1).
4. Plea or trial. South Dakota's 180-day rule sets the trial clock from the first appearance, but delays the defense requests don't count (SDCL 23A-44-5.1).
5. Sentence. A Class 6 felony reaches two years and $4,000, and Class 5 reaches five years (SDCL 22-6-1). Both come with a presumption of probation (SDCL 22-6-11), and a Deuel judge can choose county jail of up to a year instead (SDCL 22-6-1.1).

Penalties climb steeply. Classes A, B and C carry life. Below that, the maximums drop by class: a Class 1 felony can bring 50 years in prison; Class 2, 25; Class 3, 15; and Class 4, 10 (SDCL 22-6-1).

• Charged with murder, first-degree manslaughter or kidnapping? Then a Deuel judge must see the defendant before any bond is set.
• In a domestic case, a judge must hear of it before release. Meanwhile the Deuel defendant must keep clear of the alleged victim (SDCL 25-10-40, 25-10-43).
• At jury picking, each side may cut 20 people with no reason given if the charge is Class A, B, C or 1. For a lower felony, it's 10 (SDCL 23A-20-20).
• Victims may address the court on release, the plea and the sentence (S.D. Const. art. VI, § 29).

Prosecution belongs to the State's Attorney. Send mail to PO Box 590, Clear Lake, SD 57226, or phone 605-874-2840.

Defense for those without money comes by asking the judge at the first appearance (SDCL 23A-40-6). Deuel pays that lawyer, using a public defender office, appointed attorneys or contract attorneys (SDCL 23A-40-7, 23A-40-8). Later, the court can make the defendant reimburse the county. A lien can be filed on property, but a home can't be foreclosed for it (SDCL 23A-40-10, 23A-40-15).

Questions about how Deuel picks appointed counsel go to the clerk, 408 4th Street West, Clear Lake, SD 57226, 605-874-2120.

Three state tools cover Deuel cases, and the first one costs nothing:

• Find a Court Date: free. Search by the person's name or case number, or print the Deuel calendar for today and the following nine workdays.
• Public Access Record Search: $20 per search, charged even with zero results. It returns short summaries of public criminal files as far back as 1989.
• UJS eCourts: docket entries on public cases.

The courthouse has a public terminal where case records can be looked up, 408 4th Street West, Clear Lake, SD 57226. For full files or anything filed before 1989, call the clerk, 605-874-2120.

Deputies serve arrest and bench warrants anywhere in Deuel. Their office is on the courthouse's first floor, 408 4th Street West, Clear Lake, SD 57226, 605-874-8212. The Clerk of Courts at 605-874-2120 can also check a name. If you know the case number, UJS ePayments will show an active warrant on it. For statewide searches, Corrections runs a Most Wanted page of state escapees and walkaways. The Sex Offender Registry comes from the Attorney General's office. To deal with a Deuel warrant, reach a defense lawyer before anything else. That lawyer can go with them to surrender at the court that issued it.

Federal charges from Deuel land in the Northern Division of the U.S. District Court for the District of South Dakota, which sits at 102 Fourth Avenue SE, Aberdeen, SD 57401. Clerk questions go to Sioux Falls: 400 S. Phillips Ave., Room 128, Sioux Falls, SD 57104, 605-330-6600.

• A detention hearing, held when the Deuel defendant first appears in federal court, decides release or custody (18 U.S.C. 3142).
• Up to trial, the U.S. Marshals hold a Deuel defendant in a federal case. Their Aberdeen office is at 102 Southeast 4th Avenue, Suite 409, Aberdeen, SD 57401, 605-226-1794.
• Pretrial Services and U.S. Probation share the courthouse at 102 Fourth Avenue SE, Aberdeen, SD 57401, 605-377-2625.

• After sentencing, search the Federal Bureau of Prisons inmate locator.

No. The Deuel case keeps going. The detainer matters on release day:

1. ICE lodges Form I-247A at whichever host jail has the person.
2. It asks that jail to hold them up to 48 hours after they would otherwise be released (8 CFR 287.7(d)).
3. Agents from the St. Paul Field Office, 1 Federal Drive, Suite 1601, Fort Snelling, MN 55111, 612-843-8600, take custody.
4. The ICE Online Detainee Locator shows where they go next.

Any immigration worry belongs in the first talk with the defense lawyer. Under SB 7 (SL 2025, ch 100), counties and cities here may not block anyone from telling federal officers a person's immigration status.

A Deuel felony sentence to prison puts the person under the South Dakota Department of Corrections. Short misdemeanor terms are served in a county jail that Deuel pays to use.

• Type their name or inmate number into the DOC offender locator.
• Corrections keeps its main office on the Pierre campus at 3200 East Highway 34, with mail c/o 500 East Capitol Avenue, Pierre, SD 57501, 605-773-3478.
• Our South Dakota state prisons guide profiles every facility.

Court Services runs probation for the courts. Parole after prison is a DOC job.

Juvenile court in South Dakota covers kids age 10 and older, and in Deuel those cases are heard in circuit court (SDCL 26-8C-2). Release to a parent is the norm. Detention takes an intake officer's finding that a listed reason applies, and it must be the least restrictive choice (SDCL 26-8C-3).

Moving a Deuel teen into adult court requires a transfer hearing, where the judge must find adult court serves both the child and the public (SDCL 26-11-4). The Watertown detention center also runs a juvenile unit under its roof at 14 1st Ave Southeast, Watertown, SD 57201, 605-882-6284. For where a Deuel teen would be placed, call Court Services at 314 Sixth Avenue, Suite 6, Brookings, SD 57006, 605-688-4208.

South Dakota's Constitution carries Marsy's Law (S.D. Const. art. VI, § 29). When a victim asks, the law promises:

• timely notice of hearings, and a seat at them;
• a voice at Deuel hearings on release, at any plea deal and at sentencing;
• full restitution;
• prompt word of any release or escape.

To get a free alert when the person is released, sign up on SAVIN or phone 844-299-4608. Juvenile cases fall outside SAVIN. For those, and for restitution help, contact the Deuel State's Attorney at 605-874-2840, PO Box 590, Clear Lake, SD 57226.
