House-sitting in France: The Legal Framework for Homeowners and Guardians

Commodatum: The Contractual Framework for House-sitting

Definition and Founding Articles

Commodatum, or loan for use, is defined by Article 1875 of the Civil Code: “A loan for use is a contract by which one party delivers an item to another for their use, on the condition that the borrower returns it after having used it.”

Three other articles specify the nature of this contract:

• Article 1876: “This loan is essentially gratuitous.” This is the cardinal condition that distinguishes commodatum from tenancy. If the beneficiary pays rent, or even a lump sum for the use of the dwelling, it shifts to another legal framework (tenancy, sub-tenancy, paid accommodation) with its own rules.

• Article 1877: “The lender remains the owner of the loaned item.” Commodatum does not transfer any ownership. The guardian never becomes the owner or tenant of the dwelling.

• Article 1878: specifies that any commercial good that is not consumed by use can be the subject of a commodatum. A dwelling clearly falls into this category.

Why Commodatum Applies to House-sitting

The practice of house-sitting as it develops between private individuals in France perfectly matches the definition of commodatum:

• The homeowner delivers their dwelling to the guardian (meaning: entrusts its use to them).

• The guardian uses it (they live there, take care of it).

• The contract is gratuitous: no rent or financial benefit changes hands.

• The guardian must return the dwelling at the end (upon the homeowner's return).

This gratuitous nature defines everything else. It excludes qualification as a tenancy (which would require rent) or sub-tenancy (which would also require payment). It also excludes the tax obligations associated with tenancy (e.g., declaration of rental income).

The Guardian's Obligations Under Commodatum

Article 1880 of the Civil Code specifies a central obligation: “The borrower is bound to take care of the loaned item, as a good family man, in its custody and preservation.” This somewhat dated phrase practically means: the guardian must take care of the dwelling as a reasonable homeowner would. No noisy parties with damage, no modifications to the dwelling without agreement, no negligent behavior.

This obligation is one of means, not results. The guardian must do what is necessary to properly maintain the house and pets. If they act diligently and an unforeseen event still occurs (an appliance breaks down, an elderly animal dies of natural causes), their liability is not engaged. For it to be engaged, a clear fault on their part would have to be proven: gross negligence, abandonment of post, or behavior contrary to normal use of the dwelling.

The Homeowner's Obligations Under Commodatum

Article 1888 of the Civil Code stipulates that the lender (the homeowner) must allow the guardian to enjoy the item for the agreed duration of the loan. In practice: the homeowner cannot demand the guardian's early return without serious reason, nor evict them without notice during the agreed period.

Article 1890 also stipulates that the homeowner must reimburse the guardian for any extraordinary, necessary, and urgent expenses incurred during the sit. Specifically: an emergency plumber called for a leak, or an emergency veterinarian bill for the pet, must be reimbursed to the guardian upon presentation of receipts. Conversely, current expenses (water, electricity consumption, pet supplies) are not systematically the homeowner's responsibility; this is a matter to clarify before the sit.

Is a Written Contract Necessary?

Commodatum does not require a written form to exist. A verbal agreement for a sit between friends creates a valid commodatum. In practice, however, a written exchange is strongly recommended for four reasons:

• To specify the exact start and end dates.

• To specify the spending limit the guardian can incur without prior authorization (especially for emergency veterinary fees).

• To list the items entrusted (keys, codes, possibly a vehicle, bicycle, etc.).

• To provide the guardian with a document to present in case of inspection (law enforcement, curious passers-by, administrative staff).

On Guardiens, the platform's sit confirmation and the house guide shared via messaging together constitute sufficient written evidence for most practical cases. For long or complex sits, a more formal document signed by both parties may be useful.

Liability for Animals: Article 1243 of the Civil Code

This is probably the most important legal topic in house-sitting, and the least known to both homeowners and guardians.

The Principle

Article 1243 of the Civil Code, as amended by Ordinance No. 2016-131 of February 10, 2016, states: “The owner of an animal, or the person using it, while it is under their use, is liable for the damage the animal has caused, whether the animal was under their care, or whether it was lost or escaped.”

This wording contains a key concept: “the person using it.” It means that liability is not limited to the owner of the animal. It can transfer to a third party who temporarily takes charge of the animal and exercises over it the powers of use, direction, and control.

Transfer of Care to the Guardian

French jurisprudence has clearly established that by entrusting their animal to a third party for a significant period, the owner transfers the care of the animal to that third party, who in turn becomes liable under Article 1243.

Several rulings illustrate this:

• Court of Appeal of Versailles, February 13, 1998: the person who takes charge of a third party's dog during their absence becomes the legal guardian of the animal.

• Court of Cassation, 2nd Civil Chamber, July 17, 1967: a veterinarian who hospitalizes an animal becomes its temporary guardian.

Practically, for the entire duration of the sit, it is the guardian (the house-sitter) who is legally responsible for damages the animal might cause to third parties. The animal's owner can be exempted by demonstrating the effective transfer of care, which is easy to establish with a platform like Guardiens, a signed house guide, and written communication between the parties.

Practical Consequences

This transfer of care has three consequences that every guardian must understand before accepting a sit:

1. The guardian's personal civil liability is engaged

If, during the sit, the dog bites a passer-by, escapes its leash and causes an accident, or damages a third party's property, the guardian will have to compensate the victim. Their civil liability guarantee (included in their home insurance or subscribed separately) must therefore be up-to-date and cover this type of situation.

2. The guardian must be able to prove legitimate guardianship

In case of dispute, they must be able to demonstrate that they indeed had care of the animal at the time of the events, within a clear framework. The written record (platform exchanges, house guide, sit dates) is invaluable at that moment.

3. The animal's owner is not entirely exempt

If the incident is related to a known defect of the animal that the owner did not disclose (reactive dog, dangerous behavior, history of biting), the owner's liability may be re-engaged for failure to inform the guardian. This is why the homeowner's duty of transparency at the time of the sit is not just a matter of courtesy: it is also a legal matter. Any behavioral specifics must be explicitly stated in the house guide.

Cases of Exemption

The guardian can be exempted from liability in three cases, identified by jurisprudence:

• Force majeure: an unforeseeable, irresistible, and external event beyond their will (e.g., a clap of thunder that frightens the animal and makes it run away).

• Fault of a third party: external behavior that triggered the incident (e.g., a passer-by aggressively provoking the animal).

• Fault of the victim: behavior of the victim themselves that caused or aggravated the incident (e.g., a person ignoring the guardian's warning and approaching a growling dog).

These exemptions remain rare in jurisprudence: judges are strict about the guardian's responsibility. The best prevention remains prudence with the animal, adherence to the owner's instructions, and transparency in case of incident.

Insurance that Covers the Guardian on This Topic

The civil liability guarantee present in any comprehensive home insurance contract generally covers damages caused by an animal under the care of the insured, including temporarily. However, the guardian must check with their insurer before the first sit that this extension does apply: some contracts limit coverage to animals owned by the insured and exclude temporarily entrusted animals.

Point of attention for dogs classified as dangerous (categories 1 and 2 according to French regulations). These animals are subject to a specific regime that includes dedicated owner insurance and a holding permit. Entrusting them to a private individual for care on Guardiens raises legal questions that common practice does not cover. For these cases, professional advice is necessary.

The Spirit of House-sitting

The legal framework for house-sitting in France is nothing to be afraid of. It is a coherent assembly of old and solid texts (commodatum dates back to 1804) applied to a new practice. For both homeowners and guardians, three actions are enough to comply: inform your insurer, verify your civil liability guarantee, and document the sit in writing. The rest is common sense and trust, which is precisely what we try to facilitate at Guardiens.
