Antonella and Leonel can no longer stand each other. They own a flat 50/50 and have decided to end the co-ownership before it turns into a court case. She keeps the flat and pays her ex half of its value. “What will this cost us?” they ask. It is an imaginary couple, but the question is real, and if you are in a similar position (partners, siblings or cousins), this is a breakdown of the cost of dissolving co-ownership in Spain in 2026.
The legal route they are using is called extinción de condominio, the Spanish way of ending co-ownership of a property that several people own in undivided shares (proindiviso). My main guide to dissolving co-ownership in Spain explains the process step by step. Here we stay on the money.
Why is dissolving co-ownership cheaper than a sale?
It is not a sale. It is the concrete form of a right you already had over the whole property. If the operation is designed well, you pay AJD (stamp duty on the deed) instead of TPO (transfer tax, the tax on a purchase), and AJD is far cheaper.
The final price does not depend only on the notary, the land registry and AJD. The real driver is how the compensation is structured, which value is declared, and whether Spanish income tax (IRPF), municipal land value tax (plusvalía municipal) or an unexpected TPO assessment can appear afterwards.
Who pays the costs when co-owners split a property in Spain?
In an ordinary sale, article 1455 of the Spanish Civil Code puts most of the notary fees (roughly 70%) on the seller unless the parties agree otherwise. In a dissolution of co-ownership there is no legal rule, so practice decides. The usual arrangement looks like this:
- The notary is split according to each person’s share.
- The land registry and AJD are paid by whoever keeps the property, because it is their title that gets registered.
- The gestoría (the administrative agent who files the taxes and the registration) is normally paid by the person who is awarded the property.
- Municipal land value tax, when it applies, is declared by the person leaving the co-ownership.
What costs make up the bill?
- Notary. It depends on the value declared in the deed and on the number of pages. The fee rises from the fifth page on, and you should assume about 30 pages for a standard deed with annexes. A notary and land registry fee calculator will give you a first estimate.
- Land registry. This is the cost of registering that you are now the sole owner. The invoice is issued to whoever keeps the property.
- Valuation, if you cannot agree on the value. Expect €300 to €600 depending on size, type of property and location.
- Gestoría, for the taxes and the registration. Roughly €300 to €550 depending on the value.
- AJD, the big saving. You do not pay it on the whole value, only on what you acquire ex novo, meaning the part that was not yours before.
Stamp duty (AJD) rates by region in Spain
AJD is set by each autonomous region. The table shows the general rate and what it would cost on the acquisition of a share worth €100,000.
| Region | General AJD rate | Tax on a €100,000 share |
|---|---|---|
| Basque Country | 0% | €0 |
| Navarre, Ceuta and Melilla | 0.5% | €500 |
| Madrid, Canary Islands | 0.75% | €750 |
| La Rioja | 1% | €1,000 |
| Andalusia, Asturias | 1.2% | €1,200 |
| Valencian Community (from 1 June 2026) | 1.4% | €1,400 |
| Aragon, Cantabria, Castilla-La Mancha, Castile and León, Catalonia, Extremadura, Balearic Islands, Murcia | 1.5% | €1,500 |
Do you also pay municipal land value tax and income tax?
Neither is a cost of the deed itself, but both can turn into real money.
Plusvalía municipal: in a proportional dissolution you can forget about it. If there are excesses that could have been avoided, or unavoidable excesses that are not compensated, the town hall can come looking for its share.
IRPF: if the flat has gone up in value since you bought it, the person leaving can end up with a capital gain when the shares do not balance.
Examples of what a dissolution of co-ownership costs
These are approximate prices for a 50/50 dissolution with a standard deed, applying AJD at 1.5% to the half acquired ex novo.
| Property value | AJD | Notary | Land registry | Gestoría | Total |
|---|---|---|---|---|---|
| €100,000 | €750 | €821 | €356 | €340 | €2,267 |
| €200,000 | €1,500 | €936 | €511 | €415 | €3,362 |
| €400,000 | €3,000 | €1,100 | €704 | €457 | €5,261 |
| €900,000 | €6,750 | €1,353 | €978 | €611 | €9,692 |
A rate of 1.5% is the general one in most regions. In the Valencian Community it is 1.4% from 1 June 2026. Your bill may be lower with a lower regional rate or with reliefs such as those for a main residence or value limits, so check the rate in your region before you close the numbers.
A note on these figures
The notary and land registry amounts mix the official fee scale with my own experience. They are not exact, even where they show exact euros. Treat them as “this is roughly where you will land”. For precision, ask the notary and the land registry for a quote.
How can you keep the cost of dissolving co-ownership down?
The saving comes from the structure, not from haggling over fees. In a one-hour consultation (€200) I design the cheapest and safest structure for your case. If you then hand me the whole operation, the €200 is deducted from my fee. If you are the one paying someone out, the guide to buying out a co-owner in Spain covers compensation and tax. Non-residents should also read about the tax on splitting a co-owned property as a non-resident.
Frequently asked questions
How much do I save compared with buying the other co-owner’s share?
An award in a dissolution of co-ownership is taxed far better than completing your ownership by buying the share. The tax saving is usually between 5.25% and 8.5% of the share you “acquire”. The same logic applies to excesses of award: if the excess is unavoidable (an indivisible asset), it is taxed as AJD; if it is avoidable, it is taxed as TPO, and the difference is again between 5.25% and 8.5%.
What if the property is divided as part of an inheritance?
If one heir is awarded the property in the partition of the estate, with no excess or with an unavoidable excess that compensates the others, AJD does not apply. That saves 0.75% to 1.5%, and you also skip a separate step with its own notary, registry and agent.
Does it cost the same between three people as between two?
Not exactly. A one-third share is usually smaller than a 50% share, so AJD normally falls on a smaller base. Notary and registry fees tend to go up with each additional co-owner, though, because splitting the fee bases into smaller pieces pushes the fees up.
Does a mortgage make it more expensive?
Yes. It raises the notary and registry fees and adds financial and agent costs. The guide to dissolving co-ownership when there is a mortgage goes through it in detail.
Can we agree a value of 80 if the property is worth 100?
The agreement is valid between the two of you, but for tax purposes the property is valued at 100. The person awarded the property pays more AJD, and there is a risk that the tax office demands gift tax on the difference.
