Crypto and Real Estate Estate Planning in France, Spain and the UK

Transferring wealth that includes both cryptocurrency and real estate can create meaningful opportunities for families with connections to France, Spain and the United Kingdom. With well-organised documentation, a suitable will structure and early tax planning, it is possible to help heirs receive assets more smoothly, preserve investment value and reduce administrative uncertainty.

Crypto and property have different practical characteristics. Real estate is visible, registered and governed primarily by the law of the country where it is located. Crypto assets can be highly portable, but their successful transfer depends on accurate valuation, secure access information and clear instructions for executors or heirs. Bringing both asset classes into a single cross-border succession strategy is therefore a valuable step for internationally mobile families.

This guide provides a high-level overview of key inheritance, succession and tax considerations in France, Spain and the UK. Rules can change, and the correct outcome depends on factors such as residence, nationality, domicile or long-term residence status, family structure, asset location and the terms of existing wills. Personalised advice from qualified legal and tax professionals remains essential before implementing a plan.

Why a joined-up estate plan creates value

A coordinated approach can turn a complex international estate into a more manageable legacy. The goal is not simply to list assets in a will. It is to build a framework that helps the right people identify, value, administer and ultimately benefit from those assets.

• Greater continuity: heirs have a clearer path to managing properties, wallets, exchange accounts and investment records.
• Improved asset protection: secure crypto access procedures can reduce the risk that digital assets become inaccessible after death or incapacity.
• More informed tax decisions: lifetime gifts, spousal transfers, insurance structures and ownership arrangements may be considered early rather than under time pressure.
• Faster administration: organised property deeds, tax records, wallet inventories and valuation evidence can support notaries, solicitors and executors.
• Family clarity: a well-drafted plan can explain intentions and help reduce uncertainty among beneficiaries.

For families with assets in more than one country, planning is particularly valuable because succession law and inheritance tax do not always follow the same connecting factors. One country may focus on the location of land, another on the deceased person’s residence, and another on wider personal tax status.

The core distinction: succession law, tax law and asset administration

Cross-border planning becomes much clearer when these three areas are considered separately.

A property in France may be subject to French registration and succession procedures even where the owner lived elsewhere. A UK resident’s worldwide estate may be relevant to UK inheritance tax under the applicable residence-based framework. Meanwhile, crypto assets may require a careful factual analysis of ownership, custody arrangements and tax residence.

Planning for cryptocurrency as part of an estate

Crypto assets can be a powerful addition to a diversified estate, but they need a dedicated succession process. Unlike a bank account, self-custodied crypto may not be recoverable without the information needed to access it. At the same time, including private keys or recovery phrases directly in a will can be unsafe because wills may eventually become accessible through legal processes.

Create a complete but secure crypto inventory

A strong plan starts with a current inventory. This should identify the existence and location of holdings without unnecessarily exposing credentials.

• Types of crypto assets held, such as Bitcoin, Ether, stablecoins or tokenised assets.
• Wallet type, including hardware wallet, software wallet, multi-signature wallet or custodial platform.
• Exchange or platform accounts, with account identifiers and associated contact details.
• Location of hardware devices, encrypted backups and recovery instructions.
• Transaction and acquisition records that may support future tax reporting.
• Whether assets are personally owned, jointly owned, held through a company or connected with a business activity.

The inventory should be reviewed regularly. This is especially useful for fast-moving portfolios, changed wallets, new exchanges and evolving security practices.

Separate the legal instructions from the access instructions

An effective structure generally keeps inheritance instructions and technical access instructions separate.

• A will or other estate-planning document can identify who should inherit the digital assets.
• A confidential access memorandum can explain how an executor or trusted person can locate wallets, devices and credentials.
• Recovery phrases, passwords and PINs should be held using a robust and carefully considered security process rather than written openly into a testamentary document.
• Multi-signature arrangements may offer additional resilience where suitable, provided that the process is documented and trusted signers understand their role.

The ideal solution balances security during life with recoverability after death or incapacity. A plan that is highly secure but impossible for legitimate heirs to operate may fail to deliver the intended benefit.

Establish a defensible valuation record

Crypto values can move rapidly. For succession and tax purposes, the date-of-death value is often important. Executors should be able to show how values were determined, including the date, time, exchange or market source, quantity of tokens and conversion into the relevant reporting currency.

Good recordkeeping can support accurate estate accounts and help beneficiaries establish a reliable acquisition value for future tax purposes where local rules permit. It can also make conversations with notaries, accountants, tax advisers and financial institutions more efficient.

Real estate succession: the importance of the property location

Real estate has enduring value, family significance and a highly local legal character. In cross-border estates, the country where the property is located commonly has an important role in title registration, local taxes and the formalities needed before a beneficiary can sell, lease or manage the property.

For a family home, rental property, holiday residence or investment portfolio, a useful file commonly includes:

• Title deeds or land-registry references.
• Purchase documentation and evidence of acquisition costs.
• Mortgage information and lender contact details.
• Rental agreements, deposit records and property-management contracts.
• Insurance policies, maintenance information and utility contacts.
• Prior inheritance or gift records.
• Valuation reports or local market evidence.

These records can help heirs preserve the property, maintain rental income and complete registration formalities with confidence.

France: succession planning for crypto and French real estate

France has a civil-law succession system with strong protections for certain close family members. French property also typically involves notarial formalities, making early organisation especially helpful.

French forced-heirship principles

Under French domestic succession rules, children generally benefit from a protected share of the estate known as the réserve héréditaire. The available freely disposable portion depends on the number of children.

These rules can be highly relevant where a person wishes to leave a French property, crypto portfolio or other assets in a way that differs from the default family allocation. Cross-border cases may require an analysis of the EU Succession Regulation, the deceased person’s habitual residence, nationality and any valid choice of law in a will.

French inheritance tax highlights

France applies inheritance tax based on the relationship between the deceased and beneficiary, as well as the parties’ residence and the location of assets. Transfers between spouses and partners in a French civil solidarity pact, commonly known as a PACS, are generally exempt from French inheritance tax. Direct descendants may benefit from a personal allowance, currently commonly referenced as €100,000 per parent and child, before progressive rates apply. The availability of relief depends on the circumstances and should be checked at the time of planning.

Lifetime gifts can also be an important planning tool. In many cases, the parent-to-child gift allowance may be renewed after a 15-year period. This can create a structured way to pass selected assets over time while allowing the donor to make considered decisions about control, income and family objectives.

French property and notarial administration

A French notaire has a central role in many French succession matters, particularly where the estate includes French real estate. The notaire can help establish heirship, prepare the relevant succession documents, deal with property registration and coordinate tax filings.

For deaths occurring in France, the succession declaration is commonly due within six months, while different timing can apply when the death occurred outside France. Early preparation of ownership documents, valuation material and heir details can help the family meet procedural deadlines more comfortably.

Crypto in a French estate

Crypto assets should be included in the estate inventory and valued appropriately as at the relevant date. The practical priority is to ensure that the executor, heirs and advisers can identify the holdings and confirm who has authority to manage them. A professionally prepared digital-asset memorandum can complement the succession file without revealing sensitive credentials unnecessarily.

Spain: regional opportunities and property-focused planning

Spain offers significant planning opportunities, but it is essential to recognise that inheritance tax can vary substantially between autonomous communities. The value of early planning is therefore particularly high for families with Spanish property, Spanish residence or beneficiaries living in Spain.

Spanish succession law and family rights

Spain has a national Civil Code, but several autonomous communities have their own civil-law rules. Under the general Civil Code framework, descendants have protected inheritance rights, often described through the concept of legítima. Broadly, two-thirds of the estate may be reserved for descendants under the general regime, with one portion capable of being used to improve the position of one or more descendants. The exact result can differ where regional civil law applies.

This makes a locally reviewed will especially valuable. It can help align the owner’s intentions with applicable compulsory-heirship rules and with the legal process for transferring Spanish assets.

Inheritance tax differs by autonomous community

Spanish inheritance tax has a national framework, but autonomous communities may offer their own allowances, reductions and bonuses. As a result, the final tax cost can vary materially depending on factors such as:

• The autonomous community connected to the deceased or beneficiary.
• The beneficiary’s relationship to the deceased.
• The beneficiary’s pre-existing wealth.
• The value and nature of inherited assets.
• Whether the estate includes a qualifying main residence, business assets or other assets eligible for relief.
• The residence status of the parties and applicable rules for non-resident situations.

This regional variation means that an estate plan can often be made more effective through an early review of the relevant autonomous community’s rules. Families should avoid assuming that a result in Madrid, Andalusia, Catalonia, Valencia or another region will be identical elsewhere.

Spanish property transfers after death

Spanish real estate normally requires formal succession documentation and registration steps before heirs can fully deal with the property. The process often involves obtaining death and will documentation, identifying the heirs, executing a deed of acceptance and adjudication of inheritance before a Spanish notary, paying relevant taxes and updating the Land Registry.

Inheritance tax returns are generally filed within six months of death, although extensions may be available if requested in time. Urban property may also trigger municipal tax considerations, including the local tax often referred to as plusvalía municipal, depending on the facts and applicable rules.

Crypto holdings in a Spanish estate

For crypto, beneficiaries and representatives should be ready to evidence the asset type, quantity, ownership and date-of-death value. A clear digital-asset inventory is particularly useful where Spanish inheritance tax reporting is required. Keeping acquisition records also supports future tax planning if a beneficiary later sells, exchanges or otherwise disposes of inherited crypto assets.

United Kingdom: flexibility, inheritance tax and digital asset administration

The UK can offer considerable testamentary flexibility, particularly in England and Wales. This can support personalised estate planning for a mix of family property, investment property and digital assets.

Testamentary freedom and family provision

In England and Wales, an individual generally has broad freedom to decide who should inherit through a valid will. Certain family members and dependants may be able to bring claims for reasonable financial provision in appropriate circumstances, so clear drafting and professional advice remain valuable.

Scotland has different succession principles, including legal rights affecting certain moveable estate. Northern Ireland also has its own legal framework. A UK-wide estate plan should therefore take account of the jurisdiction with the closest connection to the person and the relevant assets.

UK inheritance tax overview

UK inheritance tax is commonly charged at 40% on the taxable value of an estate above available allowances, subject to the detailed rules that apply in each case. The standard nil-rate band is £325,000. A residence nil-rate band of up to £175,000 may also be available when a qualifying residence passes to direct descendants and the relevant conditions are met. The residence nil-rate band can be reduced for larger estates.

Transfers between spouses or civil partners are generally exempt from UK inheritance tax. Unused nil-rate bands can often be transferred to a surviving spouse or civil partner’s estate, potentially improving the family’s available allowances when the second partner dies.

Lifetime gifts can form part of a forward-looking plan. Some gifts may fall outside the estate if the donor survives for the required period and other conditions are met. Annual exemptions and other specific reliefs may also be relevant. The rules are technical, so documenting gifts and obtaining advice before making substantial transfers can help preserve the intended tax treatment.

Long-term UK residence and worldwide assets

The UK’s inheritance tax framework has moved toward a residence-based approach for worldwide assets, including rules for people who are long-term UK residents. The detailed application can depend on the individual’s period of UK residence, history of leaving the UK and transitional rules. This makes it especially important for internationally mobile families to review their UK connection before relying on older domicile-based assumptions.

UK property and probate

Where a person dies owning UK property, personal representatives may need a grant of probate or other authority to deal with the estate. The exact process depends on how the property is owned, its value, the existence of a will and the institutions involved. Well-organised records can help personal representatives protect the property, maintain insurance, collect rental income and complete a sale or transfer efficiently.

Crypto assets in a UK estate

Crypto assets form part of the estate for inheritance tax purposes where the deceased beneficially owned them. Executors need sufficient information to locate holdings, determine their value and establish control over them. The tax authority and professional advisers may expect a reasonable, well-supported valuation approach, particularly for material holdings.

The most practical benefit for UK families is preparation: a secure wallet-access process, reliable exchange account records, transaction history and a named person who understands the existence of the digital-asset plan. These measures can transform crypto from a difficult-to-administer asset into a properly documented part of the estate.

France, Spain and the UK: key comparison

Building a practical cross-border plan

A successful plan usually combines legal documents, tax analysis, asset records and security procedures. The following sequence can help families move forward with confidence.

1. Map every asset: list properties, crypto wallets, exchange accounts, bank accounts, investments, companies, debts and insurance arrangements.
2. Identify the legal connection of each asset: record where property is located, where accounts are held, who owns assets beneficially and where each person is resident.
3. Review existing wills: check whether they remain valid, whether they work together and whether a later will could unintentionally revoke an earlier one.
4. Assess family-protection rules: consider children, spouses, civil partners, dependants and any forced-heirship restrictions.
5. Prepare a digital-asset protocol: ensure that a trusted executor or representative can locate and recover crypto without compromising security during life.
6. Gather valuation evidence: keep property valuations, acquisition records and a method for documenting crypto values at relevant dates.
7. Review lifetime transfer opportunities: explore gifts, ownership structures and other lawful options with advice tailored to the relevant countries.
8. Coordinate advisers: cross-border matters often benefit from collaboration between lawyers, notaries, tax advisers and financial professionals in each relevant jurisdiction.
9. Update regularly: review the plan after a move of country, marriage, divorce, birth, death, major purchase, major crypto transaction or law change.

Common documents to prepare now

• A professionally reviewed will or coordinated wills where appropriate.
• A letter of wishes explaining broader family intentions.
• A confidential digital-asset memorandum.
• A property file for each French, Spanish or UK property.
• Crypto transaction records and wallet-location information.
• Current identity, residence and nationality documentation.
• Records of lifetime gifts, loans and family arrangements.
• Marriage, civil partnership, divorce and birth certificates where relevant.
• Professional valuation reports or a clear valuation methodology.

Conclusion: turn international assets into a clear family legacy

Crypto and real estate can work exceptionally well together in a long-term wealth strategy. Property can provide stability, income potential and a tangible family legacy, while crypto can add innovation, portability and diversification. The key is to give both asset classes the same level of succession planning attention.

For estates connected with France, Spain and the UK, the strongest outcomes come from early action: clear wills, accurate records, secure crypto access arrangements and advice that reflects the law of each relevant jurisdiction. With a thoughtful plan in place, families can protect value, support heirs and pass on assets with far greater confidence.
