Definition - What does On File mean?
On file means that something is kept in official record at the courts. For example, documents are kept on file.

Court clerks and other court employees are often the people who are responsible for receiving documents and putting them on file.
Justipedia explains On File
Documents are kept on file at the court so that they do not get lost, and so there is an official legal record of the document.
An example of a document that would be kept on file would be an initial complaint by a plaintiff. This document would be the catalyst that begins a lawsuit. Once a document is kept on file at a court, the court can refer to it or examine it at any time that is necessary. Official pleadings are other documents that are kept on file at courts.
