Tourist housing in co-ownership: you need the other owner's consent

Key data

If you own a property shared with another person and are thinking of putting it on vacation rental platforms, this resolution directly affects you. The General Directorate of Legal Security and Public Faith (DGSJFP) has confirmed, in its Resolution of February 27, 2026, that dedicating a co-owned property to short-term tourist rental is an act of alteration of common property that requires the agreement of all co-owners, in accordance with article 397 of the Civil Code.

The specific case arose in Conil de la Frontera: a person requested assignment of a short-term rental registration number to a property of which she was a 50% co-owner. The registrar suspended the assignment due to lack of consent from the other co-owner. The applicant appealed arguing that she had a court judgment assigning her exclusive use of the family home—in the context of a separation proceeding—. The DGSJFP dismissed the appeal.

What does this regulation establish?

The resolution clearly establishes a distinction that many property owners overlook:

• Family use of the property: a court judgment can assign one of the spouses the right to reside in the family property, even if it is co-owned by the other.
• Tourist use of the property: dedicating the property to short-term rental is an act of a different nature—it is an economic exploitation of common property—that alters its purpose and usual use.

According to article 397 of the Civil Code, no co-owner can make alterations to common property without the consent of the others, even if the alterations were advantageous to all. The DGSJFP applies this provision in its full extent: registering a property as tourist accommodation changes its purpose and constitutes an alteration that requires unanimous agreement.

The court assignment of family use protects the right to inhabit the property, but does not grant powers to exploit it economically or to modify its registration purpose without the participation of the co-owner.

Economic and operational impact

The impact is direct and blocks potential income. If you own a property in co-ownership and intend to exploit it for tourism without the agreement of the other owner, you face:

• Denial of the tourist registration number: without that number, you cannot legally operate on platforms like Airbnb or Booking in most autonomous communities.
• Impossibility of registration: the Property Registry will suspend the assignment until consent from the co-owner is proven or specific judicial authorization for that purpose is obtained.
• Risk of irregular activity: operating without a registration number may result in administrative penalties according to the applicable autonomous tourism regulations.
• Cost of judicial proceedings: if the other co-owner does not give consent, the only alternative is to go to court to request specific judicial authorization for tourist use—different from the family use judgment—, with the costs and timeframes that entails.

Who does it affect?

• Co-owners of properties at 50% or in any other proportion who want to register the property as a short-term tourist rental.
• Separated or divorced persons who have been judicially assigned the use of the family home but are not sole owners.
• Heirs in a state of co-ownership who want to exploit an inherited property for tourism.
• Investors who acquire stakes in properties with the intention of dedicating them to vacation rental.
• Tourist accommodation managers who process registrations on behalf of owners without verifying the registration status of ownership.
• Legal advisors and management firms that accompany the registration process of tourist properties.

Practical example

Ana and her ex-partner are 50% co-owners of a property in Conil de la Frontera. Following the separation, a court judgment assigns Ana exclusive use of the family home. Ana decides to register the property as a short-term tourist rental to obtain additional income.

She requests the registration number from the Property Registry. The registrar suspends the assignment because the ex-partner, 50% co-owner, has not given consent. Ana appeals arguing that the family use judgment gives her sufficient rights.

The DGSJFP dismisses the appeal: the family use judgment only allows her to inhabit the property, not to exploit it economically as a tourist accommodation. To register it as such, Ana needs either the express agreement of the ex-partner, or a new court ruling that specifically authorizes that tourist use.

Result: without that agreement or authorization, Ana cannot legally operate the property on vacation rental platforms.

What should co-owners do now?

1. Verify the registration ownership of the property before starting any tourist registration process. If there is more than one owner, you need their agreement.
2. Obtain express and written consent from all co-owners to dedicate the property to tourist rental. A verbal agreement is not sufficient for registration purposes.
3. Do not confuse the family use judgment with authorization for tourist exploitation: they are different legal titles with different effects.
4. If the other co-owner does not consent, consider requesting specific judicial authorization for tourist use—the existing family use assignment judgment is not sufficient—.
5. If you manage tourist registrations for third parties, incorporate verification of complete registration ownership as a mandatory prior step in your process.
6. Consult with a lawyer specialized in real estate law if you find yourself in a conflictive co-ownership situation before investing time and money in the registration process.
