Estate Planning Checklist for Expats in Spain: Everything You Need to Do (2026)
Most expats in Spain share a quiet assumption: that their affairs are simple enough, their family close enough, and their life organised enough that estate planning can wait. It is an understandable feeling — and one of the most costly mistakes a foreign resident can make. Spanish succession law, combined with complex cross-border tax rules, European treaty obligations, and the growing weight of digital assets, creates a set of interlocking challenges that do not resolve themselves. They accumulate.
This checklist exists because the problem is almost always one of organisation rather than intention. Expats in Spain are not careless — they are busy, they speak imperfect Spanish, and they do not know which tasks come first or where to find the right professional. The seven phases below follow a logical sequence, from legal foundations through to the conversation you need to have with your family before anything happens to you. Work through them one by one, and you will have done what the vast majority of foreign residents in Spain have never managed.
For a deeper understanding of the regulatory landscape behind each of these steps, start with the complete guide to estate planning for expats in Spain. This checklist is designed to sit alongside that guide as your practical action companion.
Phase 1 — Legal Foundation: Your Spanish Will and Election of Law
The single most important document an expat in Spain can produce is a Spanish will drawn up before a Spanish notary. Without it, your estate will be distributed according to the default rules of Spanish intestate succession — rules that may bear little resemblance to your intentions and that almost certainly conflict with the law of your home country. A Spanish will that expressly covers your Spanish assets is not optional; it is foundational.
Equally important is the election of law clause. Under EU Succession Regulation 650/2012 (Brussels IV), residents in an EU member state can choose for their estate to be governed by the law of their nationality rather than the law of their country of residence. For most non-Spanish EU nationals, this is a significant advantage. British nationals, now outside the scope of Brussels IV following Brexit, face a more complex picture — but the election clause remains relevant through bilateral agreements and private international law. Your notary should advise you on this explicitly. If they do not raise it, you should.
The notary appointment itself requires preparation. Bring your NIE (Número de Identificación de Extranjero), your passport, any existing wills from your home country, proof of address, and a clear written summary of your assets and intended beneficiaries. The appointment itself is usually straightforward, but the preparation determines whether the resulting document is accurate and complete. For a detailed walkthrough of the process, see our guide on making a will in Spain.
Phase 2 — Financial Inventory: Everything You Own in Spain
Before your family or your executors can do anything, they need to know what exists. The financial inventory phase is not glamorous, but it is the work that makes everything else possible. Start with your Spanish property — the full cadastral reference, the name of the mortgage lender if applicable, the most recent IBI (property tax) receipt, and the details of any community of owners fees. If you hold Spanish property jointly, clarify the exact ownership structure with a property lawyer.
Move on to your Spanish bank accounts. List every account by institution, account number, approximate balance, and whether the account is held jointly or individually. Include any standing orders, direct debits related to property costs, and any accounts you may have forgotten — online banks, savings accounts opened during the pandemic, or accounts used only for rental income. Then list all investments held in Spain: brokerage accounts, Spanish investment funds (fondos de inversión), life insurance policies with a Spanish insurer, and any private pension plans (planes de pensiones).
Finally, consider your pensions more broadly. If you receive a state pension from your home country, or if you have occupational or personal pensions held abroad, document these clearly. Cross-border pension inheritance is one of the most poorly understood areas of expat estate planning — rules differ significantly depending on the type of pension, the country of origin, and the beneficiary's residence. Your financial inventory should capture all of it, stored somewhere your family can actually find it.
Phase 3 — Digital Assets: Crypto, Passwords, and Online Accounts
Digital assets represent the fastest-growing category of estate planning oversight — and the one most likely to be irretrievably lost after death. If you hold cryptocurrency on a hardware wallet, the seed phrase is the only means of recovery. If you hold crypto on an exchange, your family will need account credentials, proof of identity documents, and in many cases a death certificate and legal translation before the platform will cooperate. Neither situation is simple, and both require active planning now rather than assumptions later.
The starting point is a complete inventory of every digital asset you hold: cryptocurrency by type and approximate value, the platform or wallet used to hold it, and clear instructions on how access can be obtained. This inventory must be stored securely — not in a spreadsheet on your desktop, not in an email draft, but in an encrypted vault with a trusted mechanism for transfer on death. For a full guide to the legal and practical complexities involved, read our dedicated article on crypto inheritance planning.
Beyond cryptocurrency, your digital estate includes passwords for email, banking, and financial accounts; social media profiles (which may have memorialisation options); cloud storage containing photographs and personal documents; subscription services that incur monthly charges; and any online business assets or intellectual property. Each of these deserves a line in your digital inventory. Services like Sucesio are purpose-built for exactly this challenge — allowing you to store encrypted access information that is released to named beneficiaries only when the appropriate conditions are met.
Phase 4 — Tax Planning: Spanish Succession Tax and What It Means for You
Spanish succession tax (Impuesto sobre Sucesiones y Donaciones) is one of the most misunderstood costs in expat estate planning. It is a regional tax, which means the rate and the available allowances vary significantly depending on the autonomous community where the deceased was resident or where the property is located. Andalucía, Madrid, and Valencia have each made substantial reforms in recent years that dramatically reduce the burden for close relatives; Catalonia and the Canary Islands operate under different structures entirely. Knowing which region applies to your estate is not a minor detail — it can mean the difference between a modest tax bill and a very large one.
Non-resident heirs face particular complexity. If your children or spouse live outside Spain, they may be taxed under the national rules rather than the more generous regional regime — a situation that the Spanish Constitutional Court and the Court of Justice of the EU have repeatedly examined but which remains imperfectly resolved in practice. A Spanish tax advisor (asesor fiscal) with experience in cross-border estates is not optional at this stage; it is essential. Ask specifically about double taxation treaties between Spain and your home country, and ensure your advisor has reviewed the most current regional legislation before offering you a figure.
There are legitimate planning strategies available — life insurance policies, gift and lifetime transfer rules, the timing of asset disposals — but all of them require professional guidance and sufficient lead time. Tax planning is not something to attempt at the last moment. Build it into your overall estate plan early, review it whenever your circumstances change (a new property, a change of residence region, a change in the applicable national law), and document the decisions you make.
Phase 5 — Administrative Essentials: NIE, Power of Attorney, and European Succession Certificate
Several administrative instruments are indispensable to a functioning estate plan in Spain and are too often overlooked until they are urgently needed — at which point they take weeks or months to obtain. The first is confirming that your NIE is current, correctly registered, and associated with your correct Spanish address in the Padrón municipal. This sounds routine, but inconsistencies in NIE records cause significant delays in probate and tax filings. If your NIE was issued years ago and you have moved since then, verify your registration status.
The power of attorney is the second critical instrument. A Spanish notarial power of attorney (poder notarial) allows a trusted person — a family member, a lawyer, a financial advisor — to manage your affairs in Spain in the event that you become incapacitated or are simply unable to be present in person. This is particularly important for expats who travel frequently, who have ageing parents abroad, or who spend part of the year outside Spain. A general power of attorney covers a wide range of transactions; a special power of attorney is limited to specific acts, such as selling a property or managing a specific bank account. For a full explanation of the options, see our article on power of attorney in Spain.
The European Certificate of Succession is a more technical but increasingly useful instrument introduced under Brussels IV. It allows heirs or executors to demonstrate their legal status across EU member states without needing to apostille separate national documents for each jurisdiction. If your estate spans multiple EU countries — Spanish property, French bank accounts, Belgian investments — obtaining this certificate early in the probate process saves considerable time and legal expense. Ask your Spanish notary or lawyer whether it is relevant to your specific situation.
Phase 6 — Personal Legacy: Messages, Memories, and What Cannot Be Inherited Through a Will
A will can distribute assets. It cannot transmit the things that matter most to the people who loved you. Personal legacy planning is the act of deliberately preparing the non-legal elements of what you leave behind — and it is, for most families, the part that is most remembered long after the legal and financial questions are resolved.
In practical terms, this means writing personal letters to your children, your partner, or close friends — letters that explain your values, your hopes for them, your memories of shared experiences. It means recording a voice message or video message while you are well and able. It means writing down family stories that exist nowhere else: the history of how your grandparents met, the recipe for a dish that has been made at every celebration for three generations, the names of the people in old photographs. These things disappear within one or two generations if they are not actively preserved. Personal legacy planning is not morbid — it is one of the most generous acts an expat can undertake for a family spread across different countries and cultures.
Sucesio is designed to hold this layer of legacy alongside your legal and financial documents. A secure vault that stores personal messages, photographs, and recorded memories — accessible to named family members at the right moment — extends the value of your estate planning far beyond the probate process. Completing this phase is not a bureaucratic task. It is a decision to make time for what matters.
Phase 7 — Tell Your Family: The Conversation You Must Have Before It Is Too Late
Every phase of this checklist becomes worthless if the people who need to act on it do not know it exists. Telling your family — or at minimum one trusted person — where your documents are, who your professionals are, and what your wishes are is the final and most important item on this list. It is also the one most commonly skipped, because it requires an uncomfortable conversation.
Start with the practical: tell your family where your Spanish will is registered (all wills executed before a Spanish notary are registered with the Registro General de Actos de Última Voluntad in Madrid, searchable by your heirs after death), who your notary is, and who your Spanish lawyer or gestor is. Give them the name and contact details of your Spanish accountant or tax advisor. Explain, at a high level, what assets exist in Spain and what documents they will need to locate. If you have a power of attorney in place, confirm that the person named is still willing and able to act.
Then go further. Talk about your intentions, not just your instructions. If you have written personal letters or recorded messages through a service like Sucesio, you do not need to share the contents — but you should tell your family that those messages exist and how they will be able to access them. Knowing that you have planned, that you have thought about them, and that you have left something behind beyond paperwork is a profound gift. It does not require a long conversation. It requires the decision to have it.
Frequently Asked Questions
Do I need a Spanish will if I already have a will in my home country?
Yes, in most cases. A will from your home country can theoretically cover Spanish assets, but the practical difficulties of obtaining recognition through Spanish courts — requiring certified translations, apostilles, and often lengthy delays — make a separate Spanish will strongly advisable for anyone with property or significant assets in Spain. Having two wills (one Spanish, one from your country of origin) is standard practice, provided they are carefully coordinated to avoid conflicts.
What happens to my Spanish estate if I die without a will?
Your estate will be distributed according to Spanish intestate succession rules. For residents, this typically means the surviving spouse receives a usufruct (right of use) over one third of the estate, with ownership divided among children. If you have no children, the rules become more complex. The process is significantly slower and more expensive than a planned succession, and the outcome may bear little relation to what you actually wanted.
Can my children inherit my Spanish property without coming to Spain?
Yes, with appropriate legal representation. Your heirs can grant a power of attorney to a Spanish lawyer who can handle the inheritance process on their behalf. However, they will still need to obtain an NIE, pay succession tax, and complete registration of the property in their names. The European Certificate of Succession can simplify matters if other EU jurisdictions are involved.
How does Sucesio fit into an estate plan for expats in Spain?
Sucesio is a digital vault that complements — not replaces — the work of your notary, lawyer, and tax advisor. It stores your estate planning documents, digital asset access information, powers of attorney, and personal messages in one encrypted location, with a secure transmission mechanism to named beneficiaries. It is particularly useful for expats whose families are geographically dispersed and who want to ensure that nothing is lost, delayed, or forgotten at a moment when their family is already dealing with grief.
Conclusion
The estate planning checklist for expats in Spain is not a single task to be completed in an afternoon. It is a set of seven distinct phases, each requiring attention, professional input in some cases, and regular review as your circumstances evolve. The legal foundation phase is the most urgent if you have not yet made a Spanish will. The digital assets phase is the most overlooked. The personal legacy phase is the most lasting.
What makes this checklist achievable is the act of starting — choosing one phase, booking one appointment, writing down one inventory. The rest follows with momentum. You do not need to complete everything at once. You need to begin, and to keep track of what remains.
Sucesio is built around this checklist — a secure vault that helps you complete every phase and ensures your family has access to everything they need. Start with Sucesio →
