By this time, the population around Spencer had surpassed that of Peterson, the County Seat located in the far southeastern corner of the county. A petition was passed to move the seat to the more centrally located Spencer; the motion passed 359-200 and in October 1871, the seat of government for Clay County was moved from Peterson to Spencer. At the time, Spencer lacked any building suitable for a courthouse, so residents pooled money and talent to build a two-story, 20x40 building on Main Street. This was subsequently purchased by the County for $1333 and used as the courthouse.
