When two or more people own a Spanish property together and one wants to take full ownership — a couple separating, siblings who have inherited, or partners going separate ways — the usual solution is an extinción de condominio (dissolution of co-ownership). Done correctly, it is far cheaper than selling a share, because it is taxed at a much lower rate. Done carelessly, you can pay thousands more than you need to.
At Platinum Legal Spain, our English-speaking lawyers handle dissolutions of co-ownership across the Costa Blanca, Costa Cálida and Almería — in divorces, inheritances and partnership splits. Here is how it works and why it can save you a great deal.
What is extinción de condominio?
It is the legal process by which co-ownership of a property is dissolved and the asset is consolidated into a single owner. Typically one co-owner keeps the whole property and compensates the other(s) in money for their share. It is not the same as one person “selling” their half to the other — and that distinction is exactly what saves the tax.
The big tax advantage
This is the heart of it. If a co-owner simply sold their share to the other, that sale would attract transfer tax (ITP) at the regional rate — commonly 7–10% of the share value. A genuine extinción de condominio, by contrast, is generally treated not as a transfer but as a “specification” of an existing right, and is taxed only at Stamp Duty (AJD) — usually around 1–1.5%.
On a property worth several hundred thousand euros, the difference between paying ITP and paying AJD can be thousands or tens of thousands of euros. That is why structuring the transaction correctly — as a true dissolution rather than a part-sale — matters so much.
When is it used?
- Divorce or separation — one spouse or partner keeps the family home and buys out the other’s share. See divorce in Spain.
- Inheritance — several heirs inherit a property and one keeps it, compensating the rest. See inheritance in Spain.
- Unmarried partners or friends who bought together and now want to separate their interests.
- Investors reorganising jointly owned assets.
The requirements
For the favourable treatment to apply, the dissolution needs to be a genuine one. In practice that means:
- The property is essentially indivisible — a flat or house cannot be physically split, so awarding it whole to one owner is the natural solution.
- The departing owner is compensated, normally in cash, for the true value of their share.
- It is documented in a notarial deed and registered at the Land Registry.
If the “dissolution” is really a disguised sale — for instance, awarding more than a clean buy-out, or splitting a divisible asset oddly — the tax authorities can re-characterise it and charge ITP. Getting the structure and the deed right is essential.
What about the mortgage?
If the property has a mortgage, the lender’s consent is usually needed, because the remaining owner will typically take on the whole loan. This may involve releasing the departing co-owner from the mortgage and amending it (a novación). We coordinate this with the bank as part of the process so the leaving party is cleanly released from the debt.
Capital gains and other costs
A few further points to plan for:
- The departing co-owner may have a capital gains tax exposure if the compensation reflects a gain over their original acquisition value — this should be checked in advance.
- There are the usual notary and Land Registry fees.
- Local plusvalía treatment should be reviewed, as a genuine dissolution is often not a triggering transfer, but the position must be confirmed.
Why use a lawyer
The savings only materialise if the transaction is correctly structured and documented as a true dissolution of co-ownership. We value the share fairly, draft the deed correctly, handle the mortgage release with the bank, manage the AJD and any capital-gains and plusvalía points, and register the change — protecting both the person keeping the property and the one leaving. We can act for clients abroad under a power of attorney.
A worked example: the tax saving
Imagine a couple who jointly own a home worth €300,000 (so each half is worth €150,000), and one wants to keep it. Two routes:
- One buys the other’s half as a sale — transfer tax (ITP) is charged on the €150,000 share. At, say, 8–10%, that is roughly €12,000–€15,000.
- A genuine extinción de condominio — Stamp Duty (AJD) is charged instead, on the relevant value at about 1–1.5%, roughly €3,000–€4,500 (and AJD is often calculated on the whole value, so the exact figure depends on the region).
The saving is substantial — which is precisely why the transaction must be correctly structured and documented as a true dissolution, not a part-sale.
Dividing an inherited property between heirs
Extinción de condominio is a natural fit for inheritance. When several heirs inherit a single property and one wishes to keep it, the others can be bought out efficiently through a dissolution, with the favourable AJD treatment, rather than a sale between them. We frequently combine this with the inheritance acceptance itself — see inheritance in Spain.
What if the co-owners cannot agree?
The right to dissolve co-ownership is fundamental in Spanish law — no one can be forced to remain a co-owner forever. If the owners cannot agree who keeps the property or on its value, a co-owner can ask the court to order the division. For an indivisible property such as a flat, that usually means a sale by public auction with the proceeds split — a worse outcome for everyone than an agreed buy-out, which is why early legal help to reach agreement is so valuable.
The documents and steps
- Value the property and the shares fairly.
- Agree the compensation to the departing owner(s).
- Deal with any mortgage — the remaining owner usually takes on the loan, with the bank’s consent.
- Sign the notarial deed of dissolution.
- Pay the AJD and register the change at the Land Registry.
Frequently Asked Questions
What is an extinción de condominio in Spain?
It is the dissolution of co-ownership of a property, where one co-owner takes full ownership and compensates the other(s), usually in cash, for their share. It is commonly used in divorces, inheritances and partnership splits.
Why is dissolving co-ownership cheaper than selling a share?
A genuine dissolution is generally taxed as a “specification” of an existing right at Stamp Duty (AJD, around 1–1.5%), rather than as a sale subject to transfer tax (ITP) at 7–10%, which can save many thousands of euros.
Can we do an extinción de condominio in a divorce?
Yes — it is one of the most common ways for one spouse or partner to keep the family home and buy out the other’s share efficiently, with the favourable AJD tax treatment.
What happens to the mortgage?
The lender’s consent is usually required, as the remaining owner typically takes on the whole loan and the departing co-owner is released from the mortgage by amending it. We coordinate this with the bank.
Is there capital gains tax on a dissolution of co-ownership?
There can be, for the departing co-owner, if the compensation reflects a gain over their original value. It should be checked in advance, along with the local plusvalía position.
Can you handle the dissolution if one owner is abroad?
Yes. We prepare and complete the deed, deal with the bank and register the change under a bilingual power of attorney, so neither party needs to travel.
How much tax do you pay on an extinción de condominio?
A genuine dissolution is taxed at Stamp Duty (AJD), commonly around 1–1.5%, rather than transfer tax (ITP) at 7–10% on a sale of the share — often a saving of thousands of euros, with the exact figure depending on the region.
What happens if co-owners can’t agree?
Because no one can be forced to stay a co-owner, a co-owner can ask the court to order the division. For an indivisible property that usually means a public-auction sale with proceeds split, which is why an agreed buy-out is far preferable.
Can you do an extinción de condominio on a mortgaged property?
Yes, but the lender’s consent is normally needed, as the remaining owner typically takes on the whole mortgage and the departing co-owner is released. We coordinate this with the bank.
Does an extinción de condominio trigger plusvalía?
A genuine dissolution is often not treated as a triggering transfer for the local plusvalía tax, but the position must be confirmed for your municipality and circumstances, alongside any capital-gains exposure for the departing owner.
