Short-Term and Seasonal Rental Contract: What to Include and How to Sign It Remotely

Many vacation rental and short-term landlords handle contracts improvised — a PDF over WhatsApp, a photo of a signed paper, or nothing at all. Beyond the legal risk, this creates unnecessary friction and leaves no valid audit trail. This article covers what a rental contract should contain — for both tourist and seasonal rentals — and how to manage the entire signing process without paper or in-person meetings.

Short-term tourist rental vs seasonal rental: what's the difference?

Both are fixed-duration tenancies, but they're governed differently. In Spain:

• Tourist/vacation rental: short stays (typically under 31 days) marketed through platforms like Airbnb or Booking.com. Governed by regional tourism regulations, not the general tenancy law (LAU). Often requires a tourist licence number, which must appear in the contract and in the listing.
• Seasonal rental: stays of days to months, for a specific temporary purpose — work placement, studies, medical treatment, extended holiday — without the tenant establishing permanent residency. Governed by Title III of the Urban Tenancy Act (LAU, art. 3.2). No tourist licence required, but the temporary nature of the stay must be clearly stated in the contract.

In both cases, a written contract is the only proof of the agreed terms and the only real protection against disputes, non-payment, or property damage. Without one, you're relying on goodwill.

What a short-term or seasonal rental contract must include

• Full details of the landlord/owner (full name, ID number, address)
• Full details of all guests or tenants (full name, ID/passport number, permanent address)
• Full description of the property (address, cadastral reference, tourist licence number if applicable)
• Exact check-in and check-out dates and times
• Total price and breakdown (per night/week/month), payment method and schedule
• Security deposit amount and conditions for return
• Maximum number of occupants
• Reason for stay (tourism, work, studies, medical treatment…)
• Supporting documentation for the reason of stay if required by regulation (travel booking, employer letter, medical certificate…)
• House rules (pets, smoking, noise, access hours)
• Cancellation policy and penalties
• Liability clause for damages and proper use of the property

The problem with paper contracts

For years, the standard approach was to print the contract, post or email it, wait for the guest to sign it by hand, scan it, and send it back. The result: files scattered across folders, illegible signatures, low-quality scanned PDFs, and a lingering doubt about whether any of it would actually hold up in court.

If the guest is coming from another country, the process becomes even more complicated. And if you manage several properties, it quickly turns into an unmanageable mess — especially when you need to find a specific contract quickly.

Options for signing a rental contract remotely

• Email + photo or scan: no identity verification, no document integrity guarantees, legally fragile if contested.
• DocuSign / Adobe Sign: legally valid, but expensive, generic, and completely disconnected from the rest of your rental workflow.
• Colibree Rentals Manager: signing integrated into the full rental flow — guests verify their identity, sign, attach supporting documents, and only then do you generate access to the property.

Digital signatures are legally valid in Spain and across the EU

The EU eIDAS Regulation (910/2014) recognises electronic signatures as legally valid. You don't need a qualified digital certificate for a rental contract to be enforceable: what matters is that there's a clear record showing the person signed knowingly and voluntarily, and an audit trail to prove it.

Colibree uses email verification with a one-time code: the guest enters their email address, receives a code, enters it on the platform, and only then can they sign. This creates a clear, verifiable link between the email address and the signature — which is logged as part of the file.

Document integrity: the digital seal

When you sign a paper contract, someone could theoretically swap a page, alter a clause, and reprint it. You'd never know. With a properly implemented digital contract, this is impossible.

Each time the signed PDF is generated, the system calculates a unique mathematical fingerprint of that file — think of it as placing an invisible tamper-evident seal on the document. If anyone were to change even a single character, a space, or a comma after signing, the fingerprint would change and the system would detect it immediately.

That fingerprint is recorded at the moment the contract is finalised. At any future point — months or years later — it can be used to prove that the document you have is exactly the one that was signed, with no alterations. It's the digital equivalent of initialling every page of a paper contract, but far more reliable.

The signature trail: when, from where, and on what device

Beyond the document itself, every signature leaves a technical record that becomes part of the file. This includes: the exact date and time the signature was applied (down to the second), the IP address from which the signing took place — which can be used to locate the connection geographically — and the device and browser used.

For the landlord, this means that in any dispute — "I never signed that", "I don't know what this contract is", "that's not my signature" — there is an objective, independent record that shows who signed, when, and from where. It's not a matter of trust: it's a matter of documented evidence.

All of this data is attached to the generated PDF and is accessible at any time from the platform, without needing to contact anyone or submit a request.

How it works in Colibree Rentals Manager, step by step

1. You create the contract from the platform using your property's saved template.
2. Guests receive a signing link, verify their identity with a one-time code sent to their email, and fill in their personal details.
3. They attach any supporting documents required for their reason of stay.
4. They sign digitally with their finger on mobile or with a mouse on desktop.
5. You review everything and give your approval.
6. The signed PDF is automatically generated — with the document fingerprint and the full technical signature trail for each signer — and emailed to all parties.
7. Once the contract is confirmed, you generate the property access link and send it to the guest.

Conclusion

A well-written rental contract, signed with a verifiable identity trail and protected by a document fingerprint, is not bureaucracy — it's the minimum reasonable protection for your property and your guests. The good news is that none of this requires printing, scanning, or in-person meetings.

Colibree Rentals Manager handles the full contract flow — from template to signed PDF — as part of the same platform you use to manage locks and guest access. Sign in with Google and set up your first property in minutes.
