The rise in popularity of digital assets, such as cryptocurrencies and non-fungible tokens (NFTs), along with decentralised finance (DeFi), presents new legal and practical challenges for wealthy individuals in the UK dealing with divorce and estate planning. This article offers a straightforward introductory guide for legal professionals advising High Net Worth Individuals (HNWIs), covering essential topics like disclosure requirements, valuation methods, tax implications, and estate planning strategies related to digital assets. By addressing the emerging trend of digital assets and cross-border issues, this paper emphasises why a proactive and multidisciplinary approach is essential in order to effectively protect and manage digital wealth.
The term ‘digital asset’ encompasses a broad range of tangible and intangible assets that exist in digital form. For the purposes of this paper, a digital asset is defined as ‘a digitally represented store of value or contractual right that can be transferred, stored, or traded electronically’ (adapted from Law Commission, 2023).[1] This definition includes, but is not limited to:
The legal status of digital assets as ‘property’ is a subject of ongoing development. Traditional legal concepts of property require tangibility and physical control, which do not readily apply to digital assets.[2] However, recent UK case law has started to influence the treatment of digital assets in legal proceedings. Courts have recognised the proprietary nature of cryptocurrencies, as seen in AA v Persons Unknown)[3] and Robertson v Persons Unknown[4], both of which affirmed that cryptocurrencies can be classified as property. These cases represent a significant development, as they provide a clear legal basis for treating cryptocurrencies as assets that can be subject to legal claims and remedies.
In AA v Persons Unknown, the court granted a proprietary injunction over Bitcoin, recognising the claimant's right to trace and recover dissipated crypto-assets. Similarly, Robertson v Persons Unknown reinforced this position, further solidifying the view that crypto-assets can be treated as property under English law.
The recent case of D'Aloia v Persons Unknown & others (including Bitkub Online Co Ltd)[5] has further clarified the legal status of cryptocurrencies, specifically addressing the nature of the stable coin Tether (USDT). The High Court held that USDT constitutes property under English law, describing it as ‘neither a chose in action nor a chose in possession, but rather a distinct form of property not premised on an underlying legal right’[6]. This decision is significant as it extends the concept of property to include crypto assets that do not fit neatly into traditional categories of property law. Specifically, in D’Aloia, the key question was whether digital assets possessed the essential characteristics of property: definability, identifiability, exclusivity, and transferability as defined in National Provincial Bank v Ainsworth.[7]
The D'Aloia judgment affirms that cryptocurrencies like USDT meet these criteria, paving the way for their inclusion in matrimonial assets and estate planning considerations. This evolving jurisprudence demonstrates the Courts' willingness to adapt traditional legal principles to the digital age, ensuring that the law keeps pace with technological advancements and new forms of wealth. As digital assets continue to gain prominence in personal and commercial spheres, this legal recognition will be crucial in providing certainty and protection for asset holders, divorcees, and beneficiaries alike
The implication of this recognition extends to divorce and estate planning contexts, where the ability to classify crypto as property is fundamental for equitable distribution of matrimonial assets in divorce proceedings and inheritance transfers.
This approach is evident in cases such as White v White[9], where the court emphasised the need for a fair distribution of assets regardless of their nature.
2. Property (Digital Assets etc) Bill 2024: The Property (Digital Assets etc) Bill 2024 represents a significant step in clarifying the legal status of digital assets. By defining digital assets as personal property, the 2024 Bill provides a clearer legal basis for their treatment in various legal contexts, including divorce and estate planning.[10] This clarification is essential for ownership rights, disclosure obligations, and enforcement mechanisms, aiming to fully integrate digital assets into existing legal frameworks and provide more predictable legal outcomes. However, the 2024 Bill does not address all of the legal aspects and instances of digital ownership thus leaving gaps and uncertainties. Further amendments may be required to address issues such as the treatment of DeFi instruments and the regulation of crypto exchanges.
The Law Commission's 2023 report underscored the need for legal reform concerning digital assets, highlighting the complexities and unique challenges they pose to existing legal frameworks.[11] The report addressed key areas such as the definition of digital assets, proprietary rights, and cross-border issues. For example, legal scholars argue that traditional valuation methods may not be directly applicable to digital assets due to their volatility, decentralized nature, and potential for anonymity.[12] An interdisciplinary approach combining legal, financial, and technological expertise is increasingly advocated.
The first step is to identify whether the digital or crypto asset was a ‘marital’ or ‘non-marital’ property based on when the assets were acquired: during or before the marriage. If the latter, the original value up to the marriage is separate property while any growth of the asset during marriage will be considered a marital asset. Other factors considered by the Courts in categorising a marital asset are: funds used to buy the assets (e.g. single name bank account vis-a-vis a joint one); commingling of separate property with marital property; existence of a prenup/cohabitation agreement specifying the separate non-marital nature of the digital assets; a gift to spouse during the marriage (e.g. a NFT collectible as an anniversary gift). Also of note is whether the crypto-savvy spouse may have executed a ‘deed of ownership or agency’ and formalized the title of a digital asset as owned in joint tenancy, or in trust. The digital assets could also be part of the spouse’s business inventory (if they have purchased it with corporate funds or opened a business account held at an exchange), making the asset to be divided part of the spouse’s company’s share valuation.
Disclosure of digital assets and specifically of crypto requires a deep understanding of blockchain technology and digital asset management, often necessitating a more technical approach. Rule 9.14 of the Family Procedure Rules 2010 mandates full and frank disclosure of all financial assets in divorce proceedings, and this extends explicitly to digital assets.[13] Parties are required to disclose all cryptocurrency wallets’ addresses, NFT holdings, DeFi investments, and other digital property owned or controlled by them. Given the potential for concealment due to pseudonymity and the highly advanced nature of blockchain tech, forensic accounting and blockchain analysis are indispensable tools in divorce proceedings involving crypto assets, potentially requiring the use of blockchain explorers analytics, sophisticated tracing tools, digital exchange subpoenas, and even device forensics as seen in V -v- T.[14]
In cases where digital assets are suspected of being concealed, courts have demonstrated a growing willingness to issue freezing injunction orders to preserve assets pending the outcome of the proceedings. V -v- T highlights the court's proactive approach in safeguarding assets, emphasising transparency and accountability in disclosing digital holdings during divorce.
Alongside traditional bank statements reviews (looking for money transfers to crypto exchanges), given the pseudonymous nature of blockchain transactions and the fact that crypto is held on blockchain networks, forensic accounting and blockchain analysis may be indispensable tools in divorce proceedings involving digital assets. These techniques include:
Forensic techniques and employment of tracing experts are important in high-net-worth divorces where one party may attempt to conceal assets, as seen in Wright v Wright,[15] where forensic accountants were employed to uncover the full extent of the husband's assets. The experts conducted a detailed analysis of the couple's financial records, including bank statements, tax returns, and business accounts. This investigation revealed previously undisclosed offshore investments and business interests, which significantly impacted the final settlement. The case highlights the fundamental role of forensics in ensuring a fair division of marital assets and preventing the concealment of wealth in high-stakes divorce proceedings.
The intrinsic high volatility of cryptocurrencies presents a significant challenge to valuation. The rapid fluctuations in price make it difficult to determine a fair and accurate valuation for the purpose of asset division. Courts have adopted various approaches, seeking to balance the need for certainty with the principles of fairness. Methodologies include:
Moreover, the valuation of unique and rapidly evolving digital assets, such as NFTs-collectibles, presents complex challenges beyond those posed by standard cryptocurrencies. Courts must consider factors such as the scarcity, artistic value, and potential future appreciation of the underlying metadata when determining an appropriate valuation method for the purpose of asset division. Given the subjective nature of these factors, valuation can be highly contentious and may require qualified expert evidence. Courts will take under consideration the characteristics of the specific digital asset and the available market data to arrive at a fair and defensible valuation.
Digital assets may be subject to Capital Gains Tax (CGT), Income Tax, and Inheritance Tax (IHT), thus significantly influencing settlement structuring.[16] Understanding these tax implications is essential for structuring divorce settlements in a tax-efficient manner, and careful planning can help minimise tax liabilities. For example, transferring digital assets to a spouse with lower income may reduce the tax burden at time of liquidation.
Prenuptial agreements can be invaluable tools for outlining the treatment of crypto-assets in divorce, ensuring clarity and protecting assets in view of the marriage. These agreements can specify how digital assets will be divided in the event of a separation and divorce, providing a level of certainty and predictability that may be lacking in the absence of such an agreement, mitigating potential disputes. However, the enforceability of prenuptial agreements depends on various factors, including whether both parties received independent legal advice and whether there was any duress or undue influence. In the UK, while prenuptial agreements are not automatically legally binding, they are considered highly persuasive and are often upheld by courts if properly drafted and executed.[17]
Like any other assets during divorce, digital assets will be divided either via a Court order, a mediation or negotiated agreement. The actual delivery may be executed by direct transfer of the crypto, when both parties have digital wallets set up; by liquidation, selling the crypto and diving the proceeds; or by offsetting the crypto property with other assets, so that one spouse retains the ownership of the digital asset while the other agrees to receive a larger share of other marital assets to ‘balance’ the settlement. Note that depending on the value of the crypto, there may not be sufficient real world assets to equalise the other spouse. In making any of the above choices and settlement offers, expert financial advice will be required.
Strategic estate planning should aim to minimise tax liabilities associated with inheritance tax (IHT) of digital assets. This may involve transferring assets to spouses and via trusts or Family Investment companies, Family Limited Partnerships or other mechanisms to mitigate IHT exposures, highlighting the need for proactive and informed planning. The use of trusts or corporations can also provide greater control over the distribution of digital assets and protect them from creditors. Setting up ad hoc life insurance policies to help with estate cash flow and to cover future IHT liability may also be considered.
Providing executors with clear and comprehensive instructions (Access Guides) for accessing and managing digital assets is essential. This includes providing security information, such as PINs, passwords, and recovery phrases. Clear, unambiguous guidance can prevent costly errors and ensure the testator's wishes are fulfilled.
The emergence of metaverse assets (e.g., virtual real estate and NFTs certificates of token ownership) and DeFi platforms (e.g.,DAOs, lending protocols, yield farming) presents new challenges for legal professionals. Courts and practitioners must develop conceptual technical fluency and methodologies for valuing and managing these novel assets, which often combine elements of tangible and intangible property. The lack of clear legal frameworks for metaverse assets and DeFi platforms creates uncertainty and risk for investors
The open, distributed, and permissionless nature of crypto assets necessitates coordinated international regulation. Legal professionals must remain aware of and adapt to evolving international standards and regulations, ensuring that their clients' digital assets are managed in compliance with applicable laws across jurisdictions. Initiatives such as the Financial Action Task Force (FATF) recommendations are driving global standards for digital asset regulation. However, the lack of consistent regulation across jurisdictions creates opportunities for regulatory arbitrage and increases the risk of cross-border disputes.
Legal professionals specialising in digital assets play a significant role for HNWIs, focusing on the legal aspects of cryptocurrency and blockchain technology. Their expertise spans wills planning, divorces proceedings, and wealth management, thus addressing the unique challenges and complexities associated with digital assets’ ownership. Acknowledging challenges related to volatility, regulatory uncertainties, and the potential for unethical or illegal conduct, their multifaceted role includes:
The rise of clients’ digital assets ownership presents both significant opportunities and challenges for legal professionals advising high-net-worth individuals. By staying informed and cultivating competence on the latest developments in blockchain technology, digital asset regulation, and forensic techniques, and by developing a multidisciplinary approach that combines legal expertise with financial and technical knowledge, legal professionals can effectively protect and manage the digital wealth of their clients.
Understanding the complexities of digital assets in UK divorce and estate planning requires a proactive, multidisciplinary approach, as the digital space faces unique challenges including crypto volatility, regulatory uncertainties, and potential fiduciary misconduct.

It is important to note that the complexities of digital assets are not unique to the UK, as they will differ with jurisdictional nuances. While this discussion focuses on UK law, it recognises the rapidly changing nature of the digital asset landscape. Therefore, it is advisable to examine the cross-border implications of digital assets and consider the potential for international harmonisation of legal frameworks. As the legal and tax landscape surrounding digital assets continues to evolve, ongoing vigilance and adaptation are necessary. As Alan Turing noted: “Machines take me by surprise with great frequency.” By adopting a proactive and multidisciplinary approach to their digital wealth,high-net-worth clients won’t be surprised but will effectively ensure that their digital legacy is secured for future generations.
