Williamson County

Williamson County follows Tennessee law on arrests, release, and courts. These rules are the same in every county in the state; the full set covers prosecutors, defense, and jails too.

Who decides release first

A magistrate sets bail first. In many counties that is an appointed judicial commissioner who need not be a lawyer; in others it is a general sessions judge or, when no judge can come within three hours, a court clerk. A defendant can appeal a commissioner's decision to the court.

Time to see a judge

A person arrested must be taken "without unnecessary delay" before the nearest magistrate of the county. The rule sets no number of hours.

Money bail

Magistrates and judges may set money bail, and the sheriff or a judicial commissioner accepts bonds from approved commercial bonding companies.

Tenn. Code Ann. 40-11-106

Courts

Circuit courts try felonies in each of the 32 judicial districts, except where the legislature created separate criminal courts to take the criminal cases. A general sessions court in every county holds preliminary hearings in felony cases and tries misdemeanors when the defendant gives up a jury trial in the higher court. City municipal courts hear ordinance and traffic violations.

Judges and magistrates

Voters elect circuit, criminal, and general sessions judges for eight-year terms, and all must be lawyers. Bail is often set by judicial commissioners, whom county commissions appoint for terms of up to four years; only the largest counties must require them to be lawyers.

Read from the statutes and court rules cited, 2026-09-30. Some of this is medium confidence and still being checked. trial_selection is "mixed" because Ballotpedia says trial judges run in partisan elections unless a county opts for nonpartisan ones; no statute was read for this. Which counties use judicial commissioners versus judges or clerks, and whether any county uses a misdemeanor bail schedule, was not confirmed.
