Do You Need a Spanish Will After Getting a Spanish Mortgage?

Arranging a Spanish mortgage involves a long list of paperwork: the NIE, the Spanish bank account, payslips, tax returns, bank statements and evidence of any existing loans. None of that paperwork answers a separate question that tends to surface afterwards — what happens to the mortgaged property, and the debt attached to it, if the owner dies.

This page looks at how a Spanish will fits alongside a UK will once a mortgage is in place, and how both interact with the double taxation agreement between Spain and the United Kingdom. It is general information, not legal advice; a notary and a tax adviser should confirm the detail for each family.

Once a British buyer has gone through the paperwork for a Spanish mortgage — the NIE application, the Spanish bank account, the proof of income from payslips and tax returns — the next question is often about what happens to the property if something happens to them. A mortgage adds a layer: the debt itself becomes part of the estate, and whoever inherits the property in Spain also inherits what is still owed on it.

Many clients already have a will in the United Kingdom covering their worldwide assets. The question is whether that is enough, or whether a separate Spanish will is needed for the property bought with the mortgage. There is no single answer that fits everyone, but the mechanics are well established and worth understanding before signing at the notary.

A Spanish will is drafted before a Spanish notary, in Spanish (often alongside an English version for the owner's understanding), and registered in the Central Wills Registry in Madrid. Its only purpose is to state who inherits the Spanish property — and, by extension, who takes on whatever mortgage balance remains — without requiring a foreign court process to be recognised first.

Under EU succession rules that Spain applies, a British owner can choose for the law of their nationality to govern the succession of their Spanish estate, even though the United Kingdom is no longer an EU member. That choice is usually written into the Spanish will itself, so the document and the choice of law travel together.

Spain and the United Kingdom have a double taxation agreement, and it matters here in a specific way: it governs how income and gains are taxed across both countries, but it does not decide who inherits the property. Succession and inheritance tax are handled separately, under Spanish rules for the Spanish asset and UK rules for the rest of the estate, with each country applying its own reliefs.

A local tax adviser should confirm, case by case, how any rental income from the Spanish property is reported to HMRC while the owner is alive, and how an inheritance involving Spanish real estate and an outstanding mortgage is declared later. The double taxation agreement reduces the risk of paying tax twice on the same income or gain, but it is not a substitute for proper planning of the will itself.

If a British owner dies holding only a UK will, that will can still be used in Spain, but it usually needs an official English to Spanish translation, an apostille, and a Spanish grant of probate process before the local land registry will recognise the heirs and allow them to deal with the mortgaged property. Meanwhile, the mortgage lender still expects payments or an orderly settlement, so delays in recognising the heirs can complicate matters with the bank.

None of this makes the property impossible to inherit, and a UK will is a perfectly valid starting point. The practical difference a Spanish will makes is mostly one of time and paperwork: a document drafted in Spain, referring to the Spanish asset, tends to move through the Spanish system more directly than a foreign one.

Colibrí Finances prepares the mortgage file and compares offers from more than twenty Spanish banks, but we are not notaries or tax advisers, and the will itself sits outside what a credit intermediary registered with the Bank of Spain is authorised to draft. What we do flag, as part of preparing a complete file, is that the mortgage and the will are linked: the lender will want clarity on who is responsible for the debt if the borrower dies, and a badly coordinated pair of wills can slow that down.

Our recommendation to clients buying with a mortgage is to raise the will question with a Spanish notary around the same time as signing, rather than afterwards, while the file, the NIE and the account details are already organised. Fees for our mortgage service are agreed with the client in writing before any work begins, and that agreement does not cover will drafting, which is a separate, independent service.

Spain is a relatively short flight away from most UK airports, making regular visits to a Spanish property straightforward for owners based in Britain. Many British buyers are drawn to Spain for its climate, coastal lifestyle and established expatriate communities. One practical point to bear in mind is that Spanish inheritance law differs from UK rules, so it is worth taking specific advice on how it may affect the property and one's estate. Currency movements between sterling and the euro can also affect the overall cost of purchase and ongoing expenses.

Spain and the United Kingdom have a double taxation agreement in place, and a local tax adviser should confirm how rental income or gains from Spanish property must be declared and reported to HMRC.

As the United Kingdom is no longer an EU member state, British citizens may stay in Spain for up to 90 days in any 180-day period without a visa, and must apply for a visa or residence permit for longer stays.

Since the United Kingdom uses the pound sterling (GBP) rather than the euro, buyers should factor in exchange-rate movements and currency conversion costs when paying for a property or transferring funds to Spain.
