What Is a Co-Owner: Rights, Duties & How It Works in 2026

Legal definition of a co-owner

A co-owner is any individual or legal entity that holds a fraction of the title over a real estate asset together with other people, as regulated by articles 392 to 406 of the Spanish Civil Code.

Article 392 of the Civil Code puts it this way: «Community exists when ownership of a thing or a right belongs pro indiviso to several persons.»

Pro indiviso does not mean you own «your physical part» of the property. It means you hold rights over 100% of the asset, in proportion to your share. If you hold 1/8, you hold rights over 12.5% of every euro, every week and every relevant decision affecting that property.

There are three common situations in which you become a co-owner:

• You bought the property jointly with other people.
• You inherited it together with other heirs — what is known as proindiviso hereditario in Spanish law.
• You acquired a stake in a managed co-ownership such as Vivla’s.

Co-owner vs. timeshare holder — the difference that changes everything

The two terms sound alike. The legal and financial gap between them is enormous.

A co-owner is a real owner. Public deed. Land Registry. An asset with market value. They can sell it, bequeath it, pledge it as collateral. What they hold is real estate.

A timeshare holder has a temporary use contract over an asset that belongs to someone else. No deed of ownership. No Land Registry entry. When they try to resell, the market offers somewhere between 0% and 15% of what they paid. And the maintenance fees keep arriving year after year, whatever they rise to.

The comparison on what actually matters:

• Ownership: co-owner = real owner. Timeshare holder = right of use only.
• Land Registry: co-owner = registered as titleholder. Timeshare holder = not registered.
• Resale: co-owner = at market price. Timeshare holder = secondary market is virtually non-existent.
• Inheritance: co-owner = passes freely to heirs. Timeshare holder = contractual restrictions.
• Appreciation: co-owner = yes, like any real-estate asset. Timeshare holder = no.

The confusion is historical: timeshares were marketed for decades using the word «ownership» in an intentionally ambiguous way. They were not the same thing then and they are not the same thing now.

Rights of a co-owner

The Spanish Civil Code recognises four fundamental rights that no one can strip away from you:

• Use of the entire asset (art. 394). You are not restricted to «your physical percentage» — you can use the whole property, always respecting the use of the other co-owners and the agreed purpose of the asset.
• Share in the fruits (art. 393). If the property generates income — rentals, yields — you receive your proportional share. Automatically.
• Right of division (art. 400-404). At any time, unless expressly agreed otherwise, you can demand the liquidation of the co-ownership. If the asset is divisible, it is divided. If it is not, it is sold and the proceeds are split.
• Right of first refusal and withdrawal (art. 1522). If a co-owner sells their share to a third party, you have priority to acquire it at the same price. The deadline to exercise it: 9 days from the notification of the sale.

In managed co-ownership models — such as Vivla — these four rights remain fully intact. What is added is a use-regulation framework that organises the calendar of weeks, the maintenance protocols and the exit process. With no friction.

Duties of a co-owner

Rights have a mirror image. As a co-owner, you also have duties:

• Contribute to conservation and maintenance costs (art. 395). Property tax (IBI), insurance, repairs, management. In proportion to your share. No exceptions.
• Do not alter the common asset without agreement (art. 397). No co-owner can carry out significant renovations on their own. Decisions that affect the whole require consensus — or at least a majority, depending on the type of action.
• Respect the others’ right of use. You cannot monopolise the property or prevent access for the rest.
• Be liable for damage caused. If you misuse the property and cause harm, you are responsible.

The 3 paths to becoming a co-owner

• Joint purchase. You acquire a share directly through a public deed before a notary. It is registered in the Land Registry in your name. It is the most direct route and the most common one.
• Inheritance. You receive a fraction of a property together with other heirs. The proportional share is registered in the Land Registry. It is also the most frequent source of conflict between co-owners — especially when there is no clear management protocol.
• Managed co-ownership (Vivla model). You acquire shares in a limited company (Sociedad Limitada) that holds registered title over the property. Same legal rights as a direct Civil Code co-ownership, with the advantage that everything operational — maintenance, calendar, exit — is already solved from day one.

Being a co-owner with Vivla — what changes in practice

Legally, nothing changes compared with any co-ownership under the Civil Code. Your four fundamental rights remain fully intact.

What the managed model solves is what tends to be most frustrating in ordinary co-ownerships: coordination.

• Maintenance, cleaning and check-in: handled. You do not have to coordinate it.
• Weeks calendar: a fair, pre-defined and transparent allocation system. No yearly negotiations.
• Costs: a clear annual proportional fee, with no surprises.
• Exit: a defined protocol for when you want to sell your stake. Right of first refusal between co-owners first, then external market.

It is not timeshare. It is not multipropiedad. It is real ownership with the entire operation already solved. For someone who values their time as much as their capital, the difference matters.

Frequently asked questions

Can a co-owner sell their share without asking permission?

Yes. They can sell their share freely. The rest have a right of first refusal — they can acquire it at the same price within 9 days. If they do not exercise it, the seller can sell to anyone on the market.

What happens if a co-owner dies?

Their share passes to their heirs, who automatically become co-owners. The asset is not dissolved. The heirs can continue in the co-ownership or exercise the right of division to liquidate it.

How many co-owners can there be?

The Spanish Civil Code sets no limit. Managed models work with a maximum of 8 owners per property — which translates into about 6-7 weeks of effective use per holder per year, plus the rental potential of the rest.

Can a co-owner rent out on their own?

They can rent out their use time. Renting out the whole property without the others’ agreement requires consensus. In managed models, the use regulation governs this with precision.

How are expenses split?

Always in proportion to the share. If you hold 1/8 of the property, you pay 1/8 of property tax (IBI), maintenance, insurance and management. No ambiguity.

What happens if a co-owner does not pay?

The others can claim the debt. With repeated non-payment, they can even request the dissolution of the co-ownership. In managed models there is usually a reserve fund covering operations while the situation is resolved.
