Auction institutions are generally located in the intermediate people's court, that is, Xiangyang court. However, the case is still filed in the grass-roots court. Generally, the auction should first contact the litigation service hall of the grass-roots court, which is generally the management of the filing court. You can contact the filing court (some are in the executive board, and the situation is different. Anyway, it's not their business if you contact the filing court. They will tell you which department it is and prepare the materials according to their requirements.
