LEDES 1998B Overview
LEDES 1998B is an ASCII, pipe delimited format and is currently the most-widely used ebilling standard in the legal industry.
A more complex standard, LEDES 2000, was ratified in 2000 as a successor to the Ledes 1998B format. LEDES 2000 has since been modified and will be replaced by the LEDES XML Ebilling Ver. 2 format. Both of these formats are available on this web site. A modified version of LEDES 1998B for use by international law firms and vendors, LEDES 1998B-International, was ratified in Beta format in 2005 and then modified in 2006. LEDES 1998B-International is also available on this web site.
