Estate Planning for Expats in Spain: The Complete Guide (2026)

Why Estate Planning Is More Complex for Expats in Spain

If you're an expat living in Spain — whether you're a British retired couple in Barcelona, a German entrepreneur in Madrid, or a French professional in Valencia — your estate is legally fragmented in a way that domestic residents never face.

You didn't choose to make estate planning complicated. Life did.

The Double-Asset Problem

Let's say you're a British expat with Spanish residency. Your assets might look like this:

• A flat in Madrid (Spanish property)
• A house in the UK (held in your name or a trust)
• A pension from your UK employer
• A Spanish bank account
• A savings account in Germany
• Cryptocurrency held on an exchange

When you die, these assets fall under different legal systems, different tax regimes, and different inheritance rules. Your Spanish flat is governed by Spanish civil law and Spanish inheritance tax. Your UK property falls under English law and UK inheritance tax. Your cryptocurrency lives in regulatory limbo in multiple jurisdictions.

A standard will written in your home country may not be recognised for your Spanish property. This means your family could face probate proceedings in multiple countries — each with its own costs, delays, and bureaucracy.

Spanish Succession Tax vs. Your Home Country Tax

Spain's inheritance tax (Impuesto sobre Sucesiones y Donaciones) applies based on where you were “habitually resident” at the time of death — not your citizenship. For residents, it applies to your worldwide estate. For non-residents, only to Spanish-based property.

Base rates range from 7.65% to 34% — but some autonomous communities offer up to 99.9% relief for spouses and children, while others don't. Madrid and Andalucía are favourable; Catalonia is not. And these rates may compound with your home country's inheritance tax.

The Risk of Dying Intestate as a Foreign Resident

If you die in Spain without a valid Spanish will, Spanish intestacy law applies to your Spanish assets — regardless of what you actually wanted. Your partner (if unmarried) inherits nothing. Gifts to friends or charities are impossible. Minor children require a court-appointed guardian.

What Spanish Law Says About Cross-Border Inheritance (EU Regulation 650/2012)

There is a unified legal framework for cross-border estates in Europe: EU Regulation 650/2012 (the Succession Regulation). It was created specifically to handle situations like yours.

Habitual Residence vs. Nationality

Your entire estate — wherever it's located — is handled under the law of your country of habitual residenceat the time of death. This is not your citizenship. It's where you actually live.

If you've lived in Spain for 2–3 years with strong life ties (home, job, family), Spanish law applies to your entire estate — including assets in the UK or Germany.

The “Election of Law” Clause

Regulation 650/2012 lets you choosewhich country's law governs your estate — provided you make that choice explicit in a will. If you write a will in Spain stating it is governed by Spanish law, you create certainty: Spanish courts know exactly how to proceed, and your family avoids disputes about jurisdiction.

This is why working with a Spanish notario matters. They know the legal language and can draft a will that is valid under Spanish law and recognised across the EU.

How Spanish Notaries Handle Cross-Border Estates

A Spanish notario is a state-appointed public officer. When you write a will with them, they:

1. Verify your identity and mental capacity
2. Ensure the will complies with Spanish legal formalities
3. Create a legally binding testamento notarial, recognised across the EU
4. Register the will with the Registro de Actos de Última Voluntad

The 4 Types of Assets Expats in Spain Need to Plan For

1. Physical Property

Spanish real estate is subject to Spanish inheritance law and tax. Typical costs: 7–34% inheritance tax on property value, plus notarial fees (0.5–1%), registry fees, and administrative costs. Property abroad triggers inheritance procedures in that country separately.

2. Financial Accounts

Bank accounts are frozen on death pending inheritance verification. Your family needs a death certificate, a will, and inheritance tax documentation before accessing funds. Accounts in multiple countries require action in each jurisdiction — and your family must know they exist.

3. Digital Assets — The Gap Most Wills Miss

A Spanish notarial will says nothing about cryptocurrency wallets, email accounts, password managers, cloud storage, or online businesses. Spanish inheritance law does not explicitly address digital assets. There is no legal process for “inheriting” a social media account.

4. Personal Legacy

A notarial will is for legal and financial assets. It cannot preserve a personal message, a family recipe, or a life story. Most families leave this entirely unplanned — and children grieve without ever hearing a parent's voice.

Step-by-Step: How to Start Your Estate Plan as an Expat in Spain

Step 1 — Make a Full Asset Inventory

List everything in a simple document:

• Physical: Real estate (country, address, value, mortgage), bank accounts (IBAN, bank name), investments, pensions, life insurance, jewellery, vehicles
• Digital: Cryptocurrency (exchange or wallet), email accounts, cloud storage, online businesses, domain names, password manager location
• Personal: Messages you want to leave, family documents, instructions for specific wishes

Do not put passwords in this document. Store them separately — in a password manager or a sealed envelope with your notario.

Step 2 — Write (or Update) Your Spanish Will

Visit a Spanish notario with your passport (or NIE), your asset inventory, and a rough outline of your wishes. The notario drafts the will in Spanish, you sign it, and it is registered. Cost: typically €100–300. Time: 1–2 hours. Include an election of law clause if you have assets in multiple countries.

Step 3 — Appoint a Trusted Person for Digital Assets

Your executor is usually excellent at managing property and bank accounts — but not digital assets. Consider appointing a tech-savvy family member separately. Document this in a private letter (not the will), including where your password manager is located and which accounts matter most.

Step 4 — Set Up Automatic Transmission for What Your Will Can't Cover

Your will handles legally-defined assets. For everything else, consider:

• A password manager with beneficiary access settings
• A crypto wallet with a multi-signature or inheritance setup
• A digital legacy service that stores and transmits messages, passwords, and memories automatically on death notification

Common Mistakes Expats in Spain Make

Assuming Your Home-Country Will Covers Spanish Assets

Your UK will is valid in England. But your Spanish flat is governed by Spanish law. If Spanish courts don't find a Spanish will, they apply Spanish intestacy rules — not your home country's wishes.

Leaving Crypto and Passwords With No Access Plan

You own cryptocurrency. You don't mention it in your will. You don't document the seed phrase. When you die, your family finds out about it from a bank statement — but can't access the wallet. The crypto is gone. Not stolen. Just permanently inaccessible.

Forgetting to Update Beneficiaries After Life Changes

A will written in 2015 may not reflect a 2018 marriage, a 2022 grandchild, or a 2024 property purchase. Review your will every 3–5 years and after every major life change.

How Sucesio Complements Your Spanish Will

Your Spanish will, drafted by a notario, is legally sound. It addresses property, bank accounts, and financial assets with precision.

But a notarial will has limits. It can't transmit passwords. It can't transfer crypto automatically. It can't deliver a message to your grandchild on their 18th birthday. It can't preserve family recipes. It can't notify people that you've died.

Sucesio fills that gap — as a complementary layer on top of your Spanish will, not a replacement. Where your will is static, Sucesio is dynamic: it secures your digital assets, stores physical asset documentation, and preserves personal legacy, transmitting everything automatically after death notification.

Think of it this way: your Spanish will is the legal foundation. Sucesio is the practical layer that makes your wishes actually workable.
