The LEDES™ (Legal Electronic Data Exchange Standard) Oversight Committee (“LOC”) is an international, voluntary, not-for-profit organization comprised of legal industry representatives and is charged with creating and maintaining open standard formats for the electronic exchange of billing and other information between corporations and legal vendors who provide services to them.  The LOC is dedicated to using open standards which cater to no one organization or group of organizations to uniformly satisfy the complex needs of the legal industry based on 5 basic principles: keep it simple; make it unambiguous; diverge from existing formats as little as absolutely necessary; only ask for information the law firm or legal vendor is typically able to provide from their financial system; and meet the needs of corporations, law firms and legal industry software vendors to the maximum extent possible consistent with the first four criteria.

In 1995 Price Waterhouse, LLP convened a consortium of leading legal industry time and billing system and case management system vendors in order to define a standard electronic billing format for use by the legal industry.

In 2000 the informal LEDES consortium incorporated as a non-profit mutual benefit corporation.

LEDES is now more than just an ebilling standard.  Today there are five ebilling standards, and others for the exchange of budgeting and timekeeper information.  Another standard is under development for the exchange of IP matter information.  The LEDES Oversight Committee has also been instrumental in updating and developing new UTBMS (Uniform Task Based Management System) code sets that are an integral component of the LEDES data exchange standards.

The LEDES Oversight Committee has worked with global organizations like LITIG and the judiciaries of England and Wales in developing data exchange schema.

Most importantly, the LEDES standards are a globally recognized industry-specific EDI standard for eInvoicing.
