The execution of auction procedure can generally be divided into two stages: preparation and implementation. In the preparatory stage, the enforcement court must first determine the auction institution. Entrust enforcement courts and auction institutions. But in addition to the equal relationship entrusted by the general public, they also have the unequal relationship between law enforcers and helpers. After determining the auction institution, it is necessary to entrust the evaluation of the price of the executed target and determine the auction low price accordingly. At the same time, the auction institution issues an auction announcement and is responsible for displaying the auction target. At this stage, the enforcement court shall notify the parties to be present. In the implementation stage, the auction institution is mainly responsible for the auction operation, and the enforcement court is present to supervise the auction. When there are reasons such as suspension of auction, suspension of auction, withdrawal of auction and re-auction, the court shall immediately notify the auction institution in writing. After the auction, it is necessary to preside over the auction and pay the auction target. If it is necessary to handle the transfer and transfer procedures, the enforcement court will also make corresponding rulings, and so on.
