What is a Ledes File?

The Legal Electronic Data Exchange Standard is a set of file format specifications intended to facilitate electronic data transmission in the legal industry. The phrase is abbreviated LEDES and is usually pronounced as "leeds".

A LEDES file is a machine-readable file that displays invoice data in a specific order and format. This allows a company to ingest, accept and process invoices in an industry-standard way, making processing and payment much easier.


Different Ledes file formats, defined by the industry

The file format began as a plain text file (.txt) in versions:

  • LEDES 1998 (the first "LEDES" format, created in 1998, but no longer in use.)

  • LEDES 1998B (a pipe-delimited plain text file. The standard was adopted in 1998, and it is by far the more commonly used LEDES format. It lacks some flexibility, having a rigid structure. Another disadvantage of LEDES 1998B is that invoice-level data is repeated on every line item even though it is only needed once, as it does not vary per line. Many clients attempt to impose nonstandard customizations, thus defeating the purpose of having a standard. Nonetheless, law firms prefer it for its simplicity and familiarity.)

  • LEDES 1998BI/LEDES 1998-INTL (based on the LEDES 1998B standard. This format was designed to accommodate legal bills generated outside of the United States.)

For these specific LEDES versions, the file that is delivered to the corporation is the .txt file.

The file format then switched to an extensible markup language file (XML) in versions -

  • LEDES 2000 - (adopted in 2000, is an XML format.)

  • XML E-Billing version 2 (ratified in 2006 and addresses international needs in XML format.)

  • XML E-Billing version 2.1. (ratified in 2008.)

These formats create LEDES files and appear with the .xml file extension.
