|Born||1952 (age 61–62)|
|Known for||Fiancée of Ilich Ramírez Sánchez|
|Partner(s)||Ilich Ramírez Sánchez|
She became a lawyer and worked with Jacques Vergès, defender of Djamila Bouhired, and she supports her defence of "revolutionary fighters" with income from her activities as a business lawyer.
Her fiancé Carlos is currently held in Clairvaux Prison, where he is part of the general inmate population, and their attempts to marry have been frustrated by legal issues. Conjugal visits can only be made after a civil marriage occurs; a Muslim ceremony performed in 2001 (when Carlos was married to his second wife, and Isabelle was married to her first husband) had no legal force. She believes Carlos is innocent of all his alleged crimes in Paris.
Her other clients include Stellio Capo Chichi, Youssouf Fofana (murderer of Ilan Halimi), Roger Garaudy, Mohamed Benalel Merah (father of Mohammed Merah responsible for Toulouse and Montauban shootings), Charles Sobhraj, and the Islamic Republic of Iran against the movie Argo.
