Find a lawyer with UNDT / UNAT experience

An alphabetical, source-linked starting list for staff seeking independent legal assistance. Expanded to 14 practitioners on 23 October 2026. Each entry states the basis for inclusion; a judgment appearance confirms participation in that case, not current availability or a record of success.

Start with available staff assistance. Request assistance from OSLA and check eligibility. Your staff union may also help you explore representation or funding. UNOG Staff Union’s legal-assistance guidance explains its approach.

UN Staff Union New York (UNSU): Its staff-support guidance encourages staff to consult their representative and describes OSLA’s assistance with representation and identifying counsel. Ask your representative about suitable referrals and available assistance. Contact the Union office at staffunionu@un.org or +1 212 963 7075.

How to read this directory: “Judgment record” identifies counsel named in an official judgment record. “Practice-reported” and staff-association entries describe published professional claims. Credentials are attributed to their sources; we have not independently certified current bar status. Confirm availability, conflicts, fees and the scope of any engagement directly. Inclusion is not an endorsement or an affiliation with this volunteer initiative.
