for a lawyer plus certified translation

Not one language per country — both parties read the same binding contract

German template shops give you a German-only lease your tenant can't read. DUOLEXX generates both versions in a single document, grounded in German tenancy law — your tenant understands exactly what they sign and the contract 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 security deposit be for a rental flat in Germany?
The deposit is limited to three months' net cold rent (§ 551 Abs. 1 BGB). The tenant may pay it in three equal monthly installments (§ 551 Abs. 2 BGB), the first at the start of the tenancy. A cash deposit must be held by the landlord separately and in an interest-bearing account (§ 551 Abs. 3 BGB). (as of 2001)
What notice period applies to the lease?
For the tenant the ordinary notice period is three months, and notice must be received by the third working day of a month (§ 573c Abs. 1 S. 1 BGB). For the landlord it extends to six months after more than five years and to nine months after more than eight years (§ 573c Abs. 1 S. 2 BGB). Termination requires written form (§ 568 Abs. 1 BGB). This is general information (as of 2001) and not legal advice. (as of 2001)
Do I have to register in Germany, and who provides the confirmation?
Anyone moving into a dwelling must register with the registration office within two weeks (§ 17 Abs. 1 BMG). The landlord (dwelling provider) is legally obliged to issue the move-in confirmation within two weeks (§ 19 Abs. 1 BMG). (as of 2015)
Do the same protection rules apply to housing for temporary use?
No: residential space let only for temporary use is exempt from the tenant-protection provisions that govern residential tenancies of indefinite duration (§ 549 Abs. 2 Nr. 1 BGB). (as of 2001)

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.
