for a lawyer plus certified translation

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

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

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 (Deutsch) shall prevail; the English version is a translation provided for convenience.

Frequently asked questions

How high can the deposit be at the handover?
At most three months' net cold rent. You may also pay it in three equal monthly installments, the first at the start of the tenancy. — BGB § 551 Abs. 1 and Abs. 2, as of 2001.
What if the contract states a higher deposit?
An agreement that disadvantages you is void — the statutory ceiling still applies. — BGB § 551 Abs. 4, as of 2001.
Do I earn interest on my deposit?
Yes. A cash deposit must be held in an interest-bearing account separate from the landlord's assets, and the interest belongs to you. — BGB § 551 Abs. 3, as of 2001.
By when must I register after moving in?
Within two weeks of moving in, with the registration authority. — BMG § 17 Abs. 1, as of 2015.
Must the landlord confirm my move-in?
Yes, the dwelling provider must issue your move-in confirmation within two weeks. — BMG § 19 Abs. 1, as of 2015.

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.
