If you and your partner jointly own a property on the Costa del Sol and your relationship is ending, the good news is that Spanish law gives you a far cheaper route than a normal sale to move the home into one person's name. Instead of one party "buying" the other's share as a standard purchase — which in Andalucía would trigger 7% ITP (Impuesto de Transmisiones Patrimoniales) on the half being transferred — a dissolution of co-ownership, known as an extinción de condominio, is taxed only at the much lower 1.2% AJD stamp duty in Andalucía. On a €300,000 property that is the difference between paying roughly €10,500 and around €1,800 on the half-share.
This article explains, in plain English, exactly how Costa del Sol (and Costa Almería, which is also in Andalucía) owners transfer a jointly held home after a divorce or separation in 2026 — the legal mechanism, the tax base, the paperwork at the notary, what happens with an outstanding mortgage, and how the figures differ if your property sits on the Costa Blanca or Costa Cálida instead. Wherever money changes hands, we give the real regional rate, because the correct number here can save — or cost — you thousands.
When two people (or more) own a property in undivided shares, Spanish law calls them condóminos or co-owners. An extinción de condominio — literally "extinction of co-ownership" — is the legal act by which that shared ownership ends and the property passes entirely to one party, who normally compensates the other for their share. It is explicitly recognised in the Civil Code as a division of common property, not a sale.
That distinction is the whole point. Because the tax authorities treat it as a reorganisation of existing rights rather than a transfer of property between strangers, it escapes ITP and falls under the much gentler Actos Jurídicos Documentados (AJD) stamp duty. For Costa del Sol and Costa Almería owners that means 1.2%; the equivalent is 1.5% in Murcia (Costa Cálida) and 1.4% in the Valencian Community (Costa Blanca).
AJD is not charged on the whole property value, only on the portion being consolidated into one name. If you each own 50%, the base is the value of the half-share that moves. Crucially, Spain values that share against the higher of the agreed compensation or the cadastral "valor de referencia" — the reference value the tax office assigns to the property. If you agree a figure below the valor de referencia, the tax office will still assess AJD on the reference value, so always check it before you sign. This is the same principle that governs a normal purchase, and it catches out couples who assume they can simply put a low number on the deed.
Let's use a worked example: a €300,000 Costa del Sol villa owned 50/50, where one spouse takes full ownership and pays the other €150,000 for their half. The table below compares the tax you'd pay doing it correctly as an extinción de condominio versus (incorrectly) as an ordinary sale of the half-share.
| Region (coast) | As extinción de condominio (AJD on €150,000) | As a normal sale (ITP on €150,000) | Potential saving |
|---|---|---|---|
| Costa del Sol (Andalucía) | 1.2% → €1,800 | 7% → €10,500 | €8,700 |
| Costa Almería (Andalucía) | 1.2% → €1,800 | 7% → €10,500 | €8,700 |
| Costa Cálida (Murcia) | 1.5% → €2,250 | 7.75% → €11,625 | €9,375 |
| Costa Blanca (C. Valenciana) | 1.4% → €2,100 | 9%* → €13,500 | €11,400 |
*Costa Blanca resale ITP fell from 10% to 9% for deeds signed from 1 June 2026, with an 11% band above €1M. On the Costa Cálida the correct 2026 rate is 7.75%, not the 8% still shown on many sites.
On top of the AJD you should budget the usual completion extras, which are proportionally smaller than on a full purchase because only half the value is moving:
As a rule of thumb, expect total transfer costs in the region of 2–4% of the half-share value via extinción de condominio on the Costa del Sol — a fraction of the 10–13% you'd face treating it as a resale purchase.
The key requirement is that the co-ownership is being genuinely ended — the property must end up fully in one person's name (or, in some structures, split into physically independent units). You cannot use it simply to move from 50/50 to 70/30; that is treated as a partial sale and taxed as ITP on the slice transferred.
A few points specific to divorcing or separating couples:
This is where many Costa del Sol transfers get stuck. The notary can change who owns the property, but only the bank can change who is liable for the mortgage. If both of you are named on the loan, the lender is under no obligation to release the departing party simply because the deeds have changed.
You usually have three options:
Never sign the extinción de condominio before the bank has confirmed in writing how the mortgage will be handled — otherwise the departing spouse can remain legally liable for a loan on a property they no longer own.
A frequent worry is capital gains tax on the party giving up their share. Helpfully, a genuine extinción de condominio does not normally crystallise capital gains tax for the outgoing co-owner, provided the compensation reflects their original stake and no profit is being realised — the law views it as dividing what you already owned rather than a disposal. The same logic generally spares you the municipal plusvalía (the tax on the increase in land value) on these divisions, though the local town hall's treatment should always be confirmed.
That favourable position can change if money is overpaid, if one party takes a larger slice than they contributed, or if the division is dressed up as something it isn't. This is precisely why a qualified lawyer and a clean paper trail matter — the structure you choose determines the tax you pay.
Although this guide is written for Costa del Sol owners, Mediter works across four regions and the rates diverge by autonomous community. If your jointly owned home is elsewhere, apply the correct local AJD rate from the table above: 1.2% in Andalucía (Costa del Sol and Costa Almería), 1.5% in Murcia (Costa Cálida) and 1.4% in the Valencian Community (Costa Blanca). The legal mechanism — extinción de condominio — is identical nationwide; only the stamp duty percentage and the "would-be" ITP comparison change. For a broader regional comparison see our overview of the four Costas.
If, after splitting, the departing party wants to re-enter the market, it may be worth weighing the rent vs buy decision for 2026 before committing again.
Yes, significantly. On the Costa del Sol it is taxed at 1.2% AJD on the half being transferred, versus 7% ITP if treated as a normal sale — a saving of around €8,700 on a €300,000 property. Married couples dividing the home within a court-approved settlement may even be exempt from AJD.
Not voluntarily — the deed requires both parties (or someone acting under their power of attorney). If one co-owner refuses, the other can ask a court to order the division or sale of the property, but that is slower and more costly than an agreed extinción de condominio.
The higher of the agreed compensation or the cadastral valor de referencia for the share being transferred. Always check the reference value before agreeing a buy-out figure, as the tax office will assess the tax on it even if you deed a lower price.
Yes, unless the bank formally releases one borrower. Changing the deeds does not change the loan. Arrange a novation, a new mortgage or a sale with the lender in writing before you sign at the notary.
Yes. A Spanish lawyer can act for you under a power of attorney, signed at a notary in your home country with an apostille, so you don't need to travel to Spain to complete the transfer.
Generally no, provided the compensation reflects your original share and you are not realising a profit — a genuine dissolution of co-ownership is treated as dividing what you already owned. Confirm your specific position with a lawyer, as overpayment or unequal division can change the outcome.
Dividing a jointly owned home is stressful enough without second-guessing the tax.
