This is how we build contracts — and how you check our work

Anyone who sells a legal document should be able to show what it rests on. This page sets out exactly how the contracts of SpanishRentalContract.com come about: which sources we use, how we keep track of regional rules, and how every contract is tested before it reaches you.

648answer combinations of the contract check tested automatically on every change
31legal checks per test run, from deposit level to choice of regime
19Spanish regions in the deposit database, each with source and reference date

Every claim has a statute and a reference date

Not a single clause in our contracts — and not a single claim on this site — stands without its source: the article of Ley 29/1994 (LAU), the Código Civil or the regional regulation it rests on, together with the date on which we last verified it. Not “according to experts”, but art. 36.1 LAU. That makes every claim verifiable — by you, and by your lawyer.

Regional deposit rules as a maintained database, not a footnote

Lodging the deposit (fianza) works differently in every autonomous region: a different office, a different deadline, sometimes no lodging duty at all any more. We maintain those rules as a database with, for each region, the source and the reference date — including recent changes such as the abolition of the deposit lodging duty in Andalucía as of 24 January 2026 (Ley 5/2025). The contract you generate automatically applies the rules of your region.

Tested like software, because it is software

The free contract check is run through an automated test suite on every change: all 648 answer combinations are computed and held against 31 legal checks — is the recommended regime correct, is the matching deposit correct, is the causa asked for where it is required. The contract generator and the regional deposit database also have their own automated tests, including a separate test run per region for the deposit rules. A human sometimes misses a cross-reference; a test suite does not.

Changes in the law are tracked — and worked in

Spanish tenancy law is in motion. When the Tribunal Supremo struck down core parts of the national letting register on 21 May 2026 (STS 620/2026), that was worked into our documentation and contracts. The announced national rental decree we follow until it appears in the BOE — and until then we treat it as what it is: a proposal, not law. Buyers receive a revised version free of charge for twelve months whenever a change in the law affects their model.

What we are not

We are not a law firm and do not give legal advice on your individual situation. We supply model contracts in which every clause is verifiably built on the law. In doubt, or is your situation unusual? Have your lawyer review the generated contract rather than draft one from scratch — the statute sits next to every clause, so that is an hour's work rather than half a day.

Reporting errors pays off. Found a claim without a source, an outdated reference date or a clause you believe is wrong? E-mail info@propertyhost.app. We verify it against the primary source and correct it — that is how this site was built and how it stays good.

See for yourself how it works?

The free contract check asks five questions and tells you which regime will hold — with the statute to back it.
