Who Issues Warrants in Round Rock
In Texas an arrest warrant is signed by a judge. For Round Rock that means the Williamson County District Court, which hears felonies, divorces, land title cases and civil cases without a dollar limit; the County Courts and Justice Courts issue their own warrants on the cases before them. A city with a municipal court of its own issues warrants on the tickets and ordinance cases it tries.
When a defendant misses a court date the judge issues a bench warrant, and either kind of warrant lives in the court file of the case, kept by the District Clerk for district court cases and the County Clerk for county court cases.
For Williamson County, SearchSystems opened and checked the court records page for the county at wilcotx.gov/257/Court-Case (page title: Williamson County Court Case Lookup | Williamson County, TX), which answered when SearchSystems opened it on September 23, 2026. That page belongs to a lower court, the County Courts and Justice Courts, not to the Williamson County District Court.
Texas has no single public index of every trial court case; each court's records are looked up through that court.

The Williamson County Sheriff's Office and the agency that reports for Round Rock (filed by the FBI as Round Rock Police Department) serve warrants in and around Round Rock.

How to Check for a Warrant in Round Rock
The places to check for a warrant from Round Rock:
- The court file of the case, through the District Clerk for district court cases and the County Clerk for county court cases, since a warrant is recorded in the case it was issued in.
- The District Attorney, phone 512-943-1234, which can say whether charges were filed; a warrant on a complaint follows the filing.
Not one of the Williamson County pages SearchSystems verified (the sheriff's, the court's, the prosecutor's and the records request page) is a list of open warrants, so a check means asking the court or the prosecutor about a case by name.
Clearing a Warrant from Round Rock
A warrant is recalled by the court that issued it, so clearing one from Round Rock starts with the District Clerk for district court cases and the County Clerk for county court cases: the case goes back on the calendar and the judge recalls the warrant when the person appears.
A missed date in a case before the County Courts and Justice Courts is handled by that court, not by the Williamson County District Court.
A lawyer can often arrange the appearance in advance. The District Attorney's page SearchSystems verified is at wilcotx.gov/256/District-Attorney, phone 512-943-1234.
