St. Clair County Jail

Start with St. Clair County Inmate Search. The county's inmate lookup page says the jail is staffed around the clock and gives 810-987-1700 for questions about a record or a visit. In an emergency, dial 911, not the jail.

The county's jail page lists 810-987-1700 or 810-987-1720 for bond questions. The Sheriff's Office also lists a non-emergency line, 810-985-8115. Have the full name, birth date and booking number ready, then ask which charge the bond covers.

During regular county business hours, the county says a bond must be paid at the Court. When the Court is closed, the jail accepts cash bonds and credit cards, but not from licensed bonding agents. Card payments run through 1-888-604-7888 or GovPayNow.com. Ask the desk whether a convenience fee applies.

The Port Huron court is at 201 McMorran Blvd., Second Floor, Suite 2900, 810-985-2072. The Marine City court is at 2088 South Parker, 810-765-4057. Both list Monday to Thursday 8:00 a.m. to 4:30 p.m. and Friday 9:00 a.m. to 4:30 p.m. Press 0 for the criminal and traffic clerk in Port Huron.

Bring photo ID, the inmate's full name, and the case or booking number. Under the court rule, a cash bond signed by the defendant is applied first to fines, costs and assessments before any refund. Whoever pays should keep every receipt.

Michigan Court Rule 6.106 makes release without money the starting point. The judge looks at record, past court attendance, drugs or alcohol, mental health, the seriousness of the charge, money, and family ties. Cash bail is allowed only after the judge states on the record why other conditions will not do.

A court-approved surety can post a bond for one quarter of the full bail. Or, if the judge allows it, the defendant (or a helper) deposits 10 percent in cash. On a $5,000 bail that means $1,250 to a surety or $500 cash. The 10 percent deposit is returned in full after a dismissal or acquittal. Since May 2026, the court may keep part of it only after a conviction for an MCL 780.66 offense.

Not through the jail, according to the county's own page: it excludes licensed bonding agents from the after-hours cash and credit card payment. Ask the court how and when a bondsman may file a bond. Michigan does not license bondsmen through its insurance department; agents are insurance producers approved court by court.

Michigan's rule allows it with the court's consent and proof of its value. I did not see a St. Clair County property-bond checklist. Call the district court criminal clerk at 810-985-2072 and ask what papers it wants and whether land outside the county counts.

Only in the cases listed in the state constitution, such as murder, treason, first-degree sexual conduct, armed robbery, certain violent felonies by repeat offenders, or a violent felony committed while on bail, probation or parole. The judge must find that the proof is evident or the presumption great.

The county courts page lists a public defender at 810-985-2333. The judge decides at arraignment whether you qualify, and the state expects a lawyer to be present at that first hearing. Tell the clerk right away if you need one.

Anyone under 18 is handled by the Family Division of the Circuit Court, 810-985-2031, and may not be housed with adult prisoners. The county courts page lists a Juvenile Day Treatment and Night Watch program at 1238 Michigan Rd., 810-985-5390, but it does not name a locked detention center. Ask the Family Division where the teen is held.

Commissary deposits can be made online, by phone, or at the kiosk in the Sheriff's Office lobby. Visits must be booked online first. Do not mail cash. That money goes to the inmate's account and is not bail.

Missing court can mean an arrest warrant and a forfeited bond. After notice, the defendant has 28 days to surrender before judgment may be entered. Call the criminal clerk at 810-985-2072 the same day you learn a date was missed.

For someone waiting to hear from a relative in custody, the first question is often where the criminal case will begin. In St. Clair County, Michigan , lower-level criminal charges and the opening stages of felony cases are in most situations handled in District Court . Most felony trials and felony sentencing belong in Circuit Court . Juvenile delinquency cases generally go through the Family Division of Circuit Court. The St. Clair County Prosecuting Attorney represents the state. Port Huron is the county seat.

• 72-1 District Court — 2088 S. Parker St., Marine City, MI 48039. 810-765-4057.
• 72-2 District Court — 201 McMorran Blvd., Port Huron, MI 48060. 810-985-2072.

• District Court: Hears most misdemeanors and holds the first hearings in felony cases, including arraignment and preliminary examination.
• Circuit Court: Handles felony trials, pleas, sentencing, and appeals assigned by Michigan law.
• Family Division of Circuit Court: Handles juvenile delinquency proceedings and related matters.
• St. Clair County Prosecuting Attorney: Represents the state in local criminal prosecutions.
• Appointed defense lawyer: People who cannot afford counsel in qualifying criminal cases can request an appointed attorney.
• Local jail and custody: County sheriffs normally manage local jail custody; a court may order release with conditions or continued detention.

Where does a case start? Someone arrested in St. Clair County may first be booked by police and brought before a judge or magistrate. The criminal accusation determines which court hears the court matter, and the court paperwork controls where the person charged must appear. Michigan District Courts decide most misdemeanors and handle the first steps of felonies. Circuit Court in most situations takes over a felony after a waiver or a finding of probable cause at the preliminary examination.

What happens to someone waiting in jail? The St. Clair County sheriff or another authorized jail may hold the person charged while a court considers release. Custody and release decisions are recorded as part of the criminal case. A courthouse and a detention center are not necessarily on the same property.

This guide explains the usual criminal court process in St. Clair County in plain language. The exact charge, criminal history, and judge’s findings affect the outcome. It is general information, not personal legal advice.

In St. Clair County, a misdemeanor may start with a ticket or a notice to appear, while a more serious situation can lead to arrest and booking. Examples include certain assaults without serious injury, shoplifting and some impaired-driving charges. The criminal accusation written on the paperwork matters because Michigan has different penalties for different misdemeanors.

Arraignment: what the judge decides about bail

During arraignment, the judge tells the defendant what offense is charged, explains important rights and addresses a plea and release conditions. Some people can leave on a personal promise to return; others may have money bond, supervision, travel limits or no-contact orders. A judge can also deny release where the law permits. Bail is not a punishment or proof of guilt.

The next steps once charges are read

For relatives following the case, the key distinction is this: The St. Clair County District Court may schedule a pretrial hearing. Lawyers review police reports, videos and other evidence. The prosecuting attorney may offer an agreement, dismiss a charge or proceed to trial. The person charged can contest the evidence rather than accept a plea. Jury-trial rules depend on the offense and the legally available punishment.

When the court pays for an attorney

If the defendant faces a charge that qualifies for appointed counsel and does not have enough money to hire an attorney, the judge is permitted to determine eligibility for a public defender or assigned lawyer. Request this help promptly; do not assume a defender is automatically assigned following booking.

Possible misdemeanor results

Michigan misdemeanors have different maximums. Common statutory limits include 90 or 93 days, one year, and in certain cases two years, with fines fixed by the particular statute. Some offenses also require driver-license action, restitution, classes or probation. The exact charge and prior record matter more than the county name.

A felony accusation in St. Clair County ordinarily starts with a District Court arraignment, even when the eventual trial would be in Circuit Court. Prosecutors must establish the legal basis for moving the court matter forward. A felony carries the possibility of a state-prison sentence, although not every conviction results in prison time.

Probable cause conference and preliminary examination

For a person new to the court system: Michigan generally sets a probable cause conference 7 to 14 days after felony arraignment and schedules the preliminary examination roughly 5 to 7 days after that conference, unless a legal waiver, adjournment or exception changes the schedule. At the preliminary examination the prosecution must show probable cause that a crime occurred and that this defendant committed it. That decision is not a finding of guilt.

The handoff from District Court to Circuit Court

When the alleged offense is bound over, St. Clair County Circuit Court handles the felony case. The accused person may be arraigned again, and the parties exchange evidence, negotiate, file motions or set a trial. The prosecutor has to establish guilt beyond a reasonable doubt at trial. Defendants who cannot afford legal counsel should request that the court about appointed representation.

What a felony sentence can involve

Michigan sentencing rules look at the offense statute, a record of earlier convictions, the sentencing guidelines when applicable, and any mandatory minimum. A nonviolent first offender might be eligible for probation or another lawful alternative, but some violent or repeat offenses require custody. Do not use a single felony-class chart to predict all Michigan sentences.

Murder, armed robbery, criminal sexual conduct and assaults causing serious harm are examples of grave charges that could be prosecuted in St. Clair County. Seriousness by itself does not turn a Michigan crime into a federal case. Most such charges remain in the state Circuit Court unless federal law independently applies.

Detention and defense

In practice, it works this way: A judge considers Michigan’s release rules, risk of flight, safety and legally relevant facts. A no-contact order or other condition may be imposed. Some defendants remain in jail while lawyers examine records, DNA or other scientific evidence. These charges need careful legal advice and frequently involve complicated court motions.

Trial and possible prison terms

First-degree murder carries mandatory life without parole for adults under Michigan law, subject to legally applicable exceptions and youth-sentencing rules. Second-degree murder can carry a sentence up to life imprisonment. Armed robbery and several serious criminal sexual conduct crimes can also carry very long terms. Other violent offenses have their own penalty sections. Michigan does not have the death penalty.

Victim and family support

The St. Clair County Prosecuting Attorney may have a victim-witness unit that explains hearing notices and available services. The defense attorney protects the legal rights of the person charged. The amount of time a case takes depends on witnesses, evidence, motions and the court calendar.

A youth accused of breaking a criminal law in St. Clair County in most situations appears in the Family Division of Circuit Court instead of an adult District Court. Michigan juvenile proceedings emphasize the child’s age, the offense, safety, and whether services can address the problem.

Intake and the first decision

It helps to know: After police contact, juvenile court intake may review a complaint and decide whether it needs a formal petition. Some matters can be diverted or handled through services without a full court trial. If a youth is held, the law provides for prompt judicial review, and parents or guardians should ask where the child is housed.

Hearings and possible outcomes

If a formal petition is filed, the court explains the allegations and the child’s rights. An adjudication hearing decides whether the prosecutor proved the allegation under the applicable legal standard. Outcomes can involve supervision, probation, counseling, treatment, restitution, or placement through the youth-services system where authorized.

When a juvenile might face adult-style prosecution

Special laws permit designation or waiver for certain serious offenses and ages; an adult criminal matter is not automatic simply because someone is charged with a felony. Juvenile and youthful-offender rules are complicated, so ask for an attorney experienced in youth cases. Many juvenile records are not open to the public.

Someone arrested in St. Clair County does not receive a sentence just because the police wrote a charge on a report. The prosecutor must prove the court matter or the person charged must enter a valid plea. If there is a conviction, the judge uses the exact charge and Michigan statute. The amounts below are legal limits for the listed offenses, not a promise that the judge will order those amounts. Fines can be accompanied by court costs, assessments and restitution to a victim.

Why a felony's sentencing-guidelines range may be different

Michigan does not have one statewide table saying all Class A felonies get one sentence and all Class B felonies get another. For eligible felonies, the judge calculates an offense-variable score based on how the crime happened and a prior-record-variable score based on the person's record. Those scores, the crime's offense category and its sentencing classification produce a recommended minimum prison-term range. That recommended range is different from the statutory maximum, which is the most prison time allowed for that crime. Courts can depart from a recommendation when lawful and must explain a reasonable departure. Mandatory minimums can override ordinary guideline calculations.

For example, a five-year maximum for third-degree home invasion does not mean that everyone convicted must serve five years. A particular defendant may receive a lower prison minimum, probation or another lawful sentence depending on the sentencing law and case facts. Michigan prison sentences frequently state both a minimum and a maximum; parole eligibility and release do not automatically happen on the minimum date.

What about probation, restitution and jail?

A judge may order reporting to a probation officer, drug or alcohol testing, classes, treatment, community service, and repayment of a victim's proven losses. Violating probation can lead to another court hearing and a new penalty. Some people serve a local jail term instead of being sent to state prison; others qualify for an alternative sentence. A defendant's lawyer can request the sentencing-information report and explain the actual scored range before sentencing.

St. Clair County is part of the U.S. District Court for the Eastern District of Michigan, Southern Division. This court handles violations of federal criminal law; it is separate from Michigan District Court, despite the similar names. The southeastern Lower Peninsula location of the county determines its federal judicial assignment.

Federal courthouse and contact

• Federal court: U.S. District Court, Eastern District of Michigan, Southern Division
• Courthouse: United States District Court — Eastern District of Michigan, Detroit courthouse. 231 W. Lafayette Boulevard, Detroit, MI 48226.
• Clerk’s office telephone: 313-234-5000.

What makes a crime federal?

For a person new to the court system: Examples may involve trafficking drugs in violation of federal law, bank robbery involving a federally insured institution, certain firearm violations, federal tax crimes, fraud that uses interstate communications, immigration crimes, and offenses on federal property. Crossing a state line may be relevant to some laws, but is not required for every federal charge. A serious local assault or theft is not federal simply because it is serious.

Steps in a federal criminal case

A person may be arrested on a federal complaint or indictment and then appears before a U.S. magistrate judge. The judge reviews rights, counsel and detention or release. Serious federal charges ordinarily involve grand jury indictment unless a lawful exception applies. Discovery and motions follow; a plea or jury trial determines the outcome. A federal judge imposes sentence under federal statutes and sentencing rules, with any mandatory minimums applying where required.

Federal custody and sentences

The U.S. Marshals Service handles federal pretrial custody and transportation, frequently through contracted local facilities. People receiving federal prison sentences are generally placed by the Federal Bureau of Prisons. Someone arrested within a Michigan county may therefore be housed far from the county jail and may need to be found through federal channels.
