For years, anyone in Missouri could run an arrest warrant search on Case.net and see whether a judge had issued a warrant. That changed on July 1, 2026. Under a Missouri Supreme Court rule change, the courts now keep warrant information from public view until police make the arrest.
Quick answer: Since July 1, 2026, a public Missouri arrest warrant search on Case.net no longer shows warrants that police have not yet served. The Missouri Supreme Court made the change for officer safety. If you think you have a warrant, a criminal defense lawyer can help you find out and arrange to turn yourself in on your terms.
What changed about a Missouri arrest warrant search in 2026?
The change is about who can see a warrant, not how one is issued. Judges still issue arrest warrants the same way, based on a sworn finding of probable cause. What changed is that the public no longer sees the warrant online until after the arrest.
Law enforcement asked for the change. Sheriffs argued that people who saw their warrant online sometimes ran, hid or armed themselves before officers arrived.
Why does this matter if you think you have a warrant?
Before July 2026, the first step was easy: look yourself up. Now a clean Case.net search does not mean you are clear. You may find out about a warrant only when an officer stops you for a traffic violation or comes to your home or job.
That is the worst way to be arrested. You may spend a night or a weekend in jail before you see a judge, and you lose the chance to plan for bond. Read what to do if you’re arrested in Missouri.
How can you find out if you have a warrant now?
Signs that a warrant may be out include:
- A missed court date, even on a traffic ticket
- A letter or call from a detective asking you to “come in and talk”
- A probation officer telling you a violation report was filed
- Police leaving a card at your home
A defense lawyer can contact the court, the prosecutor or the investigating officer to ask. For a missed court date, see our page on failure to appear and municipal warrants. For a probation violation, your lawyer can often learn the status from the court or your probation officer.
What does it mean to turn yourself in?
A voluntary surrender, sometimes called a walk-in, lets you choose the day and arrive with a plan. Your lawyer can:
- Confirm the warrant, the charge code and the bond amount
- Ask the court to lower or change the bond before you go in
- Schedule the surrender so you can get in and out the same day when possible
- Make sure you do not answer questions without counsel
Surrendering also shows the court you are not a flight risk. That can help at a bond reduction hearing. Learn more about how bail works in Missouri.
What if police want to talk to you first?
A detective’s call is often the first sign that police are building a case, and a warrant may follow. Do not go in alone. Read what to do when questioned by police and what to do if you are the target of a criminal investigation. Early pre-charge defense can sometimes stop prosecutors from filing charges at all.
Frequently asked questions
Can I still do a Missouri arrest warrant search online?
Not for unserved warrants. Since July 1, 2026, a public Missouri arrest warrant search on Case.net does not show a warrant until after the arrest.
Does a warrant expire in Missouri?
Generally, no. An arrest warrant stays active until it is served or the court recalls it. Waiting it out usually makes things worse.
Can a lawyer get my warrant recalled?
Sometimes. For missed court dates, especially on traffic and municipal cases, a lawyer can often ask the court to recall the warrant and set a new date.
Will I go to jail if I turn myself in?
The jail will usually book you. With a planned surrender and bond arranged ahead of time, many people go home the same day.
