Once the decision to separate is made, the family home is usually the hardest conversation: it is the couple's biggest asset and the most emotionally loaded one. The good news is that the legal exits in Spain are well trodden — and their costs differ enormously. This guide lines them up so you can decide with numbers rather than in the heat of the moment.

The starting point: the home belongs to both of you (and both must sign)

It does not matter who paid more instalments or who still lives there: if the home is jointly owned — under the matrimonial community regime or as co-owners in undivided shares — selling 100% of it requires both signatures. Neither of you can sell the whole house alone, although in theory either could sell their undivided half (rare, and at a knock-down price). Nor can anyone be trapped forever: Spanish law (art. 400 of the Civil Code) says no one is obliged to remain in co-ownership, so there is always a legal way out. It is, incidentally, the same co-ownership situation you find when selling an inherited house between siblings.

The three ways out

  • Sell to a third party and split the proceeds. The most common route and usually the best price: the home is sold on the open market, the mortgage is cancelled at completion and each of you receives your share. A clean break, with liquidity to start over.
  • Condominium dissolution (extinción de condominio). One of you keeps the home and compensates the other in cash. Tax-wise it is far cheaper than a purchase between exes — details in the next section.
  • Court-ordered division. If there is no agreement, either party can ask the court to divide the joint asset; since a flat cannot be split, it ends in a public auction: the worst possible price, plus legal costs, plus one or two years of proceedings. A mediocre agreement almost always beats a good lawsuit.

Condominium dissolution: the cheap way for one of you to keep the home

It is signed in a notarial deed: the co-ownership is dissolved, one party takes 100% of the property and compensates the other in cash (normally the value of their half). The key is the tax treatment: it is not taxed as a purchase — which in the Valencian region would pay transfer tax (ITP) at the general rate of 9% (in force since 1 June 2026; 10% before) — but as stamp duty, AJD at 1.4% (the general rate since that same date; 1.5% before) on the value of the share awarded. On a €200,000 home, taking over your ex's half costs about €1,400 in AJD versus €9,000 in ITP: more than six times less. It requires agreeing on the value, a deed, and sorting out the mortgage with the bank. One caveat for the party who leaves: if the home is worth more today than when you bought it, the tax office may treat the compensation received as a capital gain in their income tax.

The joint mortgage: the divorce settlement does not release you from the bank

The most expensive mistake in Spanish divorces: agreeing in the settlement that "he/she keeps the house and the mortgage" and believing you are out of the loan. Towards the bank you both remain debtors until you sign a novation releasing the co-borrower — which the bank is not obliged to accept: it will reassess the remaining borrower's solvency and may demand guarantors or new terms — or until the loan is cancelled. If your ex stops paying and your name is still on the loan, the bank will come after you too, whatever the settlement says. If you sell to a third party instead, the debt is cancelled at the notary with the sale proceeds: here is how selling with a mortgage works.

Taxes if you sell: capital gains and the reinvestment exemption

When you sell, each of you declares half of the gain in your Spanish income tax (rates of 19% to 30%). There are two important lifelines under the tax agency's rules: the gain is exempt if you reinvest your share in a new main home within two years (before or after the sale), and the property still counts as your main home if you moved out less than two years ago — relevant for the spouse who left when the couple separated. Over-65s are exempt with no reinvestment required. Add the municipal plusvalía tax, paid by each owner on their half. Run the real numbers with the selling-costs calculator and start with the figure that puts order into everything else: a free valuation based on closed sales in the area.

FAQs

Can my ex sell the property without my signature?

No. Selling the whole home requires both signatures. They could only sell their undivided half (rare and heavily discounted) or request a court division, which usually ends in an auction at a poor price for both.

Which is cheaper: dissolution or buying my ex's half?

Dissolution: 1.4% AJD on the share awarded versus 9% ITP on a purchase (Valencian general rates since June 2026). On €100,000, about €1,400 versus €9,000.

Does the divorce settlement take me off the mortgage?

Not towards the bank: you need a novation with co-borrower release accepted by the lender, or to cancel the loan with the sale. Until then you answer for the debt, whatever the settlement says.

Do we pay income tax if we sell because of the divorce?

Yes, each on your half of the gain, unless you apply the exemption for reinvestment in a new main home (two-year window) or the over-65 exemption.
