How to Prevent Squatting and Illegal Stays in Your Vacation Rental

Illegal occupation and overstaying guests are two of the biggest fears for vacation rental owners in Spain. While the actual risk is low compared to long-term rentals, it exists — and preventing it is much easier than solving it after the fact. This guide covers preventive measures, identity verification, what to do if it happens, and how the legal framework protects you.

Let's start by separating two situations that are constantly confused: illegal occupation (someone enters your property without your consent) and overstaying (a legitimate guest who refuses to leave when their booking ends). Both are problematic, but they have very different legal solutions.

Illegal Occupation vs. Overstaying

Illegal occupation (squatting)

Someone enters your property without any title — no contract, no booking, no permission. In the vacation rental context, this is extremely rare because:

• The property has regular activity (guest check-ins and check-outs)
• There are usually electronic locks with changing codes
• Neighbors are accustomed to movement and detect anomalies
• The owner or manager checks the property between stays

Overstaying

A guest who booked legitimately refuses to leave when their reservation ends. This is more likely than squatting, though still infrequent. The key legal point is that the guest has a tourist accommodation contract (not a lease), which makes eviction significantly easier.

Situation	Probability	Eviction process	Estimated time
Illegal occupation	Very low	Criminal complaint (usurpation)	Days to weeks
Overstaying (tourist)	Low	Express eviction / complaint	Weeks
Non-paying tenant (long-term)	Medium	Judicial eviction	6-18 months

The advantage of vacation rentals over long-term rentals is clear: without a lease agreement, the guest doesn't have LAU protection and eviction is much faster.

Preventive Measures

1. Identity Verification Before Arrival

The most effective measure. If you verify the guest's identity before they arrive, you drastically reduce the risk of problems.

• Request ID document (DNI/passport) before check-in
• Compare the data with the booking
• Use the mandatory guest registration as a natural filter — a guest who refuses to provide their data is a red flag

2. Electronic Locks with Temporary Codes

Locks with codes that change for each booking are the best security investment for a vacation rental:

• The code only works during the booking period
• When the booking ends, the code stops working
• No physical keys to copy
• Access log (who entered and when)

3. Tourist Accommodation Contract

Although not mandatory in all regions, having a signed contract specifying check-in and check-out dates gives you a solid legal basis. Check our guide on guest contracts.

4. Specific Insurance

Vacation rental insurance with legal defense coverage covers your legal costs if you need to evict a guest. More details in our guide on vacation rental insurance.

5. Clear Communication of Rules

Include in your listing and pre-arrival communication:

• Exact check-out time
• Consequences of not respecting the schedule
• Cancellation policy
• That mandatory guest registration will be performed

6. Between-Stay Inspections

Never let more than 24-48 hours pass without checking the property between bookings. If someone tries to stay, you detect it immediately.

What to Do If a Guest Won't Leave

Step 1: Direct Communication

Contact the guest and remind them the booking has ended. Often it's a misunderstanding or logistical delay. Document all communication in writing.

Step 2: Contact the Platform

If the booking was made through Airbnb, Booking, or another platform, contact their support. Platforms have protocols for these situations and can mediate.

Step 3: File a Complaint

If the guest refuses to leave:

• If they have a tourist contract: complaint for breach of contract. Since it's not a lease, the LAU doesn't apply and the process is faster.
• If they have no title: complaint for usurpation (Article 245 of the Criminal Code). Police can act immediately.

Step 4: Don't Take Matters Into Your Own Hands

Never change the lock with the guest's belongings inside, cut utilities, or use force. This can make you the offender (coercion, damages).

Guest Registration as Protection

Guest registration with SES Hospedajes isn't just a legal obligation — it's a protection tool:

• Official identification: you have the guest's real data (name, document, nationality)
• Communication to authorities: police have a record of who is in your property
• Documentary evidence: in case of conflict, you have an official record of the stay
• Deterrent effect: a guest who knows their data is registered with authorities is less likely to attempt an illegal stay

Red Flags During Booking

Watch for these signals before accepting a booking:

• Very long bookings (over 30 days) without clear justification
• Guest who refuses to provide documentation
• Cash payment without going through a platform
• Request not to register the stay
• Unverified profile or no reviews on the platform
• Request to change conditions after booking

None of these signals is definitive on its own, but a combination of several should make you reconsider the booking.

How Autoregistro Fits In

Autoregistro strengthens your protection in two ways. First: it automates guest registration, meaning every guest is officially identified with the authorities before setting foot in your property. Second: it securely archives signatures and data, giving you solid documentation in case of any legal conflict.

Guest registration is required by law, but it's also your best prevention tool. A guest who knows they're registered with the police isn't a guest who's going to try staying illegally.
