What must be included in a document filed with the court?

In legal documents filed with the court, proper identification of the case is essential. This includes details such as the case number, the names of the parties involved, and the title of the document being filed. Having this information readily available ensures that the court can correctly categorize and process the document within the appropriate case. Without proper identification, there is a greater risk of misfiling or confusion regarding which case the document pertains to, potentially causing delays in legal proceedings.

The other options, while they may play various roles in the filing process, do not hold the same critical importance as proper case identification. For instance, a signature from all parties may not always be required for every document. A clerk's stamp is typically applied after the filing process is completed and is not a prerequisite for the document itself. A payment receipt is usually associated with the filing fees but does not provide specific identification of the case.
