Frequently asked questions

How far is a guarantor liable for the rent?
It depends on the country. Cyprus: the guarantor is liable to the same extent as the tenant, unless the contract provides otherwise — Contract Law, Cap. 149 s. 86, as of 2026. Austria: liability goes no further than the guarantor has expressly declared, so a maximum amount can be set — ABGB § 1353, as of 2026. Thailand: a joint-debtor clause for a guarantor who is an individual is void — Civil and Commercial Code s. 681/1, as of 2015.
What deadlines apply towards the guarantor if the tenant does not pay?
Thailand: the landlord must notify the surety in writing within 60 days, otherwise the surety is discharged — Civil and Commercial Code s. 686, as of 2015. Portugal: the landlord must notify the guarantor of the default and the sums owed within 90 days — Código Civil art. 1041.º, n.º 5, as of 2019.
Must a rent guarantee be in writing?
It depends on the country. Germany: yes, the guarantor’s declaration must be in writing — BGB § 766 S. 1, as of 2002. Cyprus: no, the Contract Law requires no written form and even an oral guarantee can be binding — Contract Law, Cap. 149 ss. 84-85, as of 2026.
How much security can be demanded on top of the deposit?
Spain: for residential leases up to 5 years (7 if the landlord is a legal entity), at most two additional months’ rent — LAU art. 36.5, as of 2019. France: a mobility lease allows no deposit, but a guarantor is permitted — loi n° 89-462 art. 25-17, as of 2018.

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.
