What we do
We find out what happened, and we document it in a form you can actually use — a written report, dated and evidenced, that stands up in front of a lawyer or a French court. Most people come to us because something does not add up: a partner’s account of their evenings, a claim that a debtor owns nothing, a relative who stopped answering the phone.
What we investigate
These are the cases we take. If yours does not fit neatly into one of them, describe it to us anyway — most real cases do not.

FD-1164 · FBI
FBI fingerprinting in Paris
Separately from our investigation work, we take ink fingerprints on the FBI FD-1164 card for people in France who need their own FBI Identity History Summary — the official FBI background check required for many visa, immigration, residency, naturalization, and adoption files. €150 TTC per person, about 45 minutes. We also take ink fingerprints for a Canadian criminal record check — RCMP form C-216C.
Licensed, and why that matters
Private investigation is a regulated profession in France. Practising requires authorisation from the Conseil National des Activités Privées de Sécurité (CNAPS), and evidence gathered by an authorised investigator can be admissible in French proceedings where material collected privately often is not. Our authorisation numbers are published at the bottom of every page on this site.
