The moment a filer submits their filing, an authorization hold is placed on their financial account to ensure the funds for the filing are available for processing by the court upon acceptance of the filing. No money has actually been charged yet.
As stated in the Processing of Credit Cards notice that pops up on the site at the Payment Accounts page for new efiling accounts (see below): if a filing is rejected by the court or canceled by the filer, the authorization hold will automatically drop away, and the funds will be released and returned to the filer's financial account within three (3) to ten (10) business days, depending on their financial institutions policies. When the authorization hold drops away, the funds will return to the user's financial account like it never left.
Remember: a filer's financial account is never actually charged for a filing until it is accepted by the court.
Until the authorization hold is released, it will appear that the user has been charged for the rejected or canceled efiling in their financial statements.
