Jeremy Forrest appeared before magistrates in the French city last week.
His UK solicitor Phil Smith has said his client looks forward to the "full story" emerging in the coming months.
He ran away with his teenage pupil in September, sparking a Europe-wide search and prompting public appeals from both sets of families.
The pair were eventually found in Bordeaux, and Forrest was arrested on suspicion of child abduction following the issuing of a European Arrest Warrant.
