Camden Court House is built on land set aside for this purpose by James and William Macarthur at the time the town allotment plans were laid down. The brothers also offered 100 pounds towards the cost of building.The first buildings on this site were a timber lock-up and Chief Constable's residence. The present building was commenced in 1855 and completed in 1857 with cells underneath and at the rear. The building was designed during William Weaver's term as Government Architect.
A new lock-up was built to replace the old one between 1859-61.
The first Clerk of the Bench was James Pearson who was also Clerk at Cawdor, making the move when the court was transferred to Camden in 1841.
When the new courthouse was completed the Clerk of the Bench was J.B. Martin, who retained this position for 35 years.
