You’re standing in downtown Gallatin, looking at the limestone and the lawyers scurrying about, and you realize you have no idea which door leads to the actual courtroom you need. It’s a common feeling. Honestly, the Sumner County Circuit Court can feel like a maze if you aren’t there every day. Most people mix it up with General Sessions or Chancery Court, but the Circuit Court is its own beast. It’s where the "big" stuff happens—the jury trials, the high-dollar lawsuits, and the serious criminal cases that the lower courts just can’t touch.
Basically, if your legal problem involves more than $25,000 or you’re looking for a jury of your peers, you’re likely heading to the 18th Judicial District’s Circuit Court.
Who is actually in charge here?
In Sumner County, the bench isn't just one person. As of 2026, the Circuit Court is anchored by experienced hands. Judge Joe Thompson has been a fixture here for years. More recently, Judge Jennifer Nichols joined the ranks, bringing a fresh perspective to the 18th Judicial District. You might also run into Judge Dee David Gay, though he primarily handles the heavy lifting on the criminal side of the docket.
It’s not just about the judges, though. The person who keeps the gears turning is Kathryn Strong, the Circuit Court Clerk. Her office is tucked into the courthouse at 155 East Main Street. If you need a file, a form, or to pay a fine, her team is who you'll talk to. Just don't ask them for legal advice—they legally can't give it, and they’ll be the first to tell you that.

What Really Happens in Circuit Court
Most people think every court case involves a gavel and a dramatic monologue. It’s usually a lot more paperwork and waiting. The Sumner County Circuit Court handles a massive variety of issues.
- Civil Lawsuits: We’re talking personal injury, car accidents, and breach of contract. If someone owes you $50,000, General Sessions won't take the case. You have to come here.
- Divorce and Family Law: While Chancery Court handles a lot of these, Circuit Court has "concurrent jurisdiction." That’s just a fancy way of saying they both do it. If your divorce involves complex property or heated custody battles, it might end up in front of Judge Thompson.
- Criminal Appeals: If someone gets convicted of a misdemeanor in General Sessions and wants a "de novo" (totally new) trial, they come to Circuit.
- Felonies: This is the heavy stuff. Robbery, aggravated assault, or drug trafficking—these cases are usually presented to a Grand Jury first and then move into the Circuit/Criminal division.
The 18th Judicial District is pretty strict about its schedule. They have an "Uncontested/Short Motion" docket for things that take less than an hour. If you’ve got a massive trial that’s going to take three days, your lawyer has to file a Certificate of Readiness (COR). If all the lawyers don't sign that COR, you aren't getting a trial date. Simple as that.
The Jury Duty Reality Check
Getting a summons in the mail feels like a gut punch to your weekly schedule. In Sumner County, they’ve modernized a bit. You can actually sign up for text alerts by texting SUMNERJURY to (866) 426-9531. It’s a lifesaver if you don’t want to wake up at 6:00 AM just to find out the trial was settled at the last minute.

To serve here, you’ve got to be a resident of the county for at least 12 months and have a clean record—specifically, no felony convictions or crimes involving "dishonesty" like fraud. If you're over 70 or have a legitimate medical excuse, you can get out of it, but you'll need a doctor's note. They don't just take your word for it.
A few things to remember before you walk in:
- No Cell Phones: Unless it's evidence, leave it in the car. Seriously.
- Dress Code: It’s not a gala, but don't wear your "Saturday morning at Home Depot" outfit. Male attorneys have to wear coats and ties. For everyone else, "business casual" is the safest bet to avoid a side-eye from the bailiff.
- Security: You’re going to be searched. It’s Gallatin, not a war zone, but they take safety seriously. No pocketknives, no pepper spray, and definitely no recording devices without a judge's permission.
Why Most People Get the Process Wrong
The biggest mistake? Assuming you can just "tell your side" to the judge whenever you want. Circuit Court is a Court of Record. Everything is transcribed or recorded. There are strict Local Rules of Practice that govern everything from how you hand a piece of paper to the judge (the Sheriff does it, you don't) to how you stand when the judge enters.
If you’re representing yourself—what the court calls "Pro Se"—you are held to the same standard as a lawyer who went to Vanderbilt. The judge won't cut you slack on the rules of evidence just because you didn't go to law school. It’s a tough spot to be in.

Navigating the Gallatin Courthouse
The physical location can be confusing because there are multiple buildings. The main Circuit Court operations are at 155 East Main St., Gallatin, TN 37066.
If you’re looking for the Criminal Court Clerk specifically, they’re sometimes over at 117 W. Smith Street at the Criminal Justice Center. It’s only a few blocks away, but in a July heatwave in Tennessee, those blocks feel long if you're running late for a 9:00 AM docket.
Actionable Steps if You Have a Case
If you find yourself involved with the Sumner County Circuit Court, don't just wait for something to happen.
- Check the Docket: Visit the official
sumnercourts.comwebsite. They keep the dockets updated so you can see when you're actually scheduled to appear. - Download the App: Believe it or not, there’s a Sumner TN Circuit Court Clerk App on the Apple and Google stores. It’s actually decent for checking records and schedules.
- Get Your Paperwork in Order: If you’re filing a name change or a divorce without kids, the clerk's office has packet forms. Fill them out before you get to the window.
- Confirm the Building: Double-check if your hearing is in the main courthouse or the Criminal Justice Center. A five-minute mistake can result in a "Failure to Appear" warrant if it’s a criminal matter.
- Hire a Local Expert: If your case is complex, find an attorney who specifically practices in the 18th District. They know the "flavor" of how Judge Thompson or Judge Nichols runs their room, which is often more important than what’s in the law books.
The Sumner County Circuit Court is the backbone of the local legal system. It's busy, it's formal, and it's where the most significant life changes—from the end of a marriage to the start of a prison sentence—actually happen. Respect the process, follow the local rules, and you'll find the experience a lot less intimidating.
