This is a court order that allows a plaintiff to go to someone's premises and seize documents. However, the entry of the plaintiff must be with that person's permission. An Anton Piller order has been described as a private search warrant. This is used in extreme cases when a prospective defendant might destroy documents, especially computer files, if they knew a court case was coming. For example, when seeking an Anton Piller order, the victim must show that s/he had a business relationship with the defendant and that the defendant is likely to be in possession of documents that can help prove the fraud, such as bank account statements, letters to and from the victim, and internal memos between members of the fraud scheme.
