Instead of several hundred €

for a lawyer plus certified translation

Not one language per country — both sides read the same binding version

Template shops give you a French-only or English-only version. DUOLEXX generates both in a single document, grounded in France tenancy law — guarantor understands exactly what they sign and it stays enforceable in France.

Governing Language Version

This document consists of two language versions. In the event of any discrepancy or question of interpretation, the version in the governing legal language (Français) shall prevail; the English version is a translation provided for convenience.

Why DUOLEXX instead of just asking an AI?

An AI writes text fast. That doesn't make it legally sound, bilingual and ready to sign. That's exactly the difference.

Grounded in local law

Every document follows the law of the chosen country — researched clauses, not a generic template from the web.

Authoritative language + translation

The binding version in the legal language, alongside an understandable translation. A chat rarely delivers both, soundly, at once.

Verifiable signature

Two-party signature with a SHA-256 integrity proof — provable that both signed the same wording.

Finished, not just text

PDF, signature, archive and share link in one flow — an AI chat only hands back raw text.
