Police custody and voluntary interview: the first 48 hours
Police custody lasts 24 hours, extendable once with the prosecutor's authorisation, and longer for organised crime. Since the Act of 14 April 2011, a person in custody may speak with their lawyer for thirty minutes and be assisted at every interview and confrontation. The lawyer reviews the record of the notification of rights, the medical certificate and the interviews already conducted, and may submit written observations that are added to the file.
The voluntary interview (audition libre) follows similar rules: you may leave at any time and be assisted by a lawyer if the offence carries a prison sentence. In both cases, the right to silence is not a confession and cannot be held against you. The rights are detailed in the police custody guide and the glossary entry on rights in police custody.
