Left-Behind Items in a Vacation Rental: Rules, Deadlines and What to Do

Cleaning finishes, you close the door and the next day the guest messages you: they have left a toothbrush, a charger or something considerably worse behind. Left-behind items are one of the most common incidents in holiday rentals and, well managed, they are no more than an anecdote. Poorly managed, they end up in an argument over shipping costs, a negative review or a serious problem if the item is valuable. This protocol covers the legal side, the deadlines, who pays for shipping and how to keep everything on record.

Do you have to keep them? Custody duty and the Civil Code

The Spanish Civil Code governs the relationship between accommodation and guests' belongings. Articles 1783 and 1784 treat belongings brought into accommodation by travellers as a necessary deposit, and case law has reinforced the host's duty of custody, regardless of whether there is a specific deposit agreement. In practice: whatever comes into the property with the guest falls within your area of responsibility during the stay.

When something is left behind after checkout, there is no single national rule setting deadlines for holiday rentals; the general framework is the duty to return the item, industry practice and, in some cases, the applicable regional rules. The practical reading is simple: you are the temporary custodian of someone else's property, so you must identify it, keep it safe and make every effort to return it. Found property also follows the criteria of Article 615 of the Civil Code: return it to its owner and, if the owner is unknown, deposit it with the competent authority. In your case the owner is usually identifiable: it is the guest from a specific booking.

What you should have is your own protocol, written down and applied the same way every time. Legal certainty in these incidents comes from records, not memory.

Inventory with photos and 24-hour notice

The first step belongs to whoever cleans, and it should be on the checklist for every checkout:

1. Photograph the item where it was found, before moving it. One context shot and one close-up.
2. Label it with the booking reference, the date and who found it. A label and a sealed bag or box solve 90% of internal mix-ups.
3. Store it somewhere safe and dry, out of reach of the next stay. Do not leave it "in the bedroom wardrobe" hoping the guest will drop by unannounced.
4. Notify the guest within 24 hours through the booking channel or whichever channel you normally use. The sooner they know, the more likely they are to claim it and the less likely they are to think it was lost in your property.

Written notice leaves the trail you need: what was found, when and what options you offered. If the guest does not reply, that attempt still counts. When you write to them, describe the item precisely so they can identify it, and do not share more personal data than is necessary for shipping.

Shipping, collection and costs: who pays

Return costs are, as a general rule, the guest's: it is their item and their oversight. The reasonable approach is to ask for the full address and a payment method before sending anything, or agree on cash on delivery if the service allows it. Sending low-value items internationally can cost more than the item itself, so set it out clearly and let the guest decide.

Usual options, in order of preference:

• Collection at the property by the guest or by someone authorised in writing. No cost and no logistics.
• Post or courier with costs paid by the guest, agreed in writing in advance.
• Temporary custody until the guest decides how they want it. Set a deadline from the first notice and communicate it.

What you should not do is send the item on your own initiative and claim the cost afterwards, or promise delivery times that depend on a courier company. Agree first, send later and keep the delivery receipt.

Valuables, documents and medication

Some items need special handling:

• Identity documents, passports and cards: return as a priority. If the guest is already far away, a registered shipment with acknowledgement of receipt or hand delivery are the safest options. In extreme cases, consider depositing them with the competent authority if there is no way to make contact.
• Jewellery, electronics and valuables: separate custody, with double verification and a photographic record. Do not post photos of the item on social media or open channels.
• Medication: do not send it by post if it requires a prescription, a cold chain or is for hospital use. Notify the guest as soon as possible and agree on the safest route; if it poses a risk, seek guidance on how to proceed.
• Keys and remotes: if you keep spares, check that no others are missing. A left set of keys with the property address is a security risk, not a simple oversight.

In all these cases, avoid going through the contents of backpacks, wallets or devices. Record what is visible to identify the item and nothing more.

How long to keep items if nobody claims

There is no single legal deadline for holiday rentals. Hotel industry practice keeps left-behind items for between six months and a year; for a smaller holiday rental, an internal policy of three to six months is reasonable if it is documented in your protocol. Before disposing of anything:

• Make at least two or three written attempts to contact the guest, in different weeks.
• Record every attempt and the lack of response.
• For valuables or documents, consider handing them to the competent authority rather than making a unilateral decision.
• Clothing and valueless items can be donated or recycled after the deadline; perishables and used hygiene products should be discarded earlier, with a note in the incident record.

Disposing of someone else's property without having tried to return it is the decision that can get complicated. The rest is logistics.

Record the incident

Log every left-behind item against its booking: date found, who found it, description, photo, contact attempts and final resolution. That record serves three purposes: it prevents internal arguments about where things are, it demonstrates diligence if the guest claims, and it feeds the review or reply you may have to give later.

If the forgotten item includes keys, documents or any security element, treat it as a priority incident, not just a lost item. And if damage shows up at checkout alongside the forgotten item, the procedure for claiming it is in the guide on claiming damage on Airbnb. If the problem is of another kind — a pest issue detected during cleaning, for example — the protocol is in bed bugs in a vacation rental.

Keeping bookings, guest data and communications in one place means this kind of incident is resolved in a couple of messages, instead of rebuilding the stay from screenshots.

Practical guidance based on the Spanish Civil Code and industry practice. It is not legal advice; for high-value items or disputes involving financial claims, consult an adviser.
