He was appointed director of the law courts, successively, at Kulm (1832), Grossglogau (1834) and Halle (1840).

He retired in 1854 and died in Neisse, Silesia, Imperial Germany in 1872. Koch reconstructed the entire Prussian jurisprudence, upon the theory and practice of which his work exerted great influence.
