Crypto Assets & Separation Implications

Crypto assets such as Bitcoin, Ethereum, stablecoins, non fungible token holdings and other digital assets increasingly feature in divorce settlements and wider family law proceedings across England & Wales. FCA Research estimated 12% of the UK adult population own crypto assets. These assets are therefore no longer niche. Family lawyers now routinely encounter cryptocurrency considered alongside property, pensions, business interests and savings in financial remedy cases.

The legal status of crypto assets as property has been clarified by English courts and by the Law Commission’s work on digital assets. These developments shape how crypto investments and broader digital wealth are treated when couples separate. The practical questions that follow – disclosure, valuation, dividing cryptocurrency, tax implications and protecting digital assets – are what this article addresses.

Digital assets is a broad term covering anything of value that exists in electronic form. In the context of family proceedings, this includes cryptocurrencies, stablecoins, non fungible token collections, exchange tokens, yield-farming positions and other rights traded electronically on digital platforms. Unlike traditional digital money issued or backed by a central bank, most crypto assets operate on decentralised networks and have no physical form.

Crypto assets are a subset of digital assets. They include well-known digital currencies like Bitcoin and Ether, stablecoins such as USDT, and a wide range of smaller tokens. HMRC does not treat crypto assets as currency or money; instead, they are classified as intangible capital assets. Cryptocurrency transactions are recorded on a public blockchain ledger, which provides a degree of transparency – though the pseudonymous nature of wallet addresses means identifying the owner still requires investigation.

In practice, a family court may encounter several types of cryptocurrency holdings:

• Coins or tokens held on a cryptocurrency exchange, accessible through exchange accounts
• Assets in a private digital wallet controlled by a private key
• Hardware wallets (sometimes stored on a USB stick or similar device), secured by seed phrases
• Positions locked in DeFi protocols or staking arrangements
• Non fungible token collections with a public address on a blockchain

Each of these creates different issues for disclosure and enforcement. A public key or public address on a blockchain can be traced, but assets held in cold storage or on an overseas digital exchange may be harder to locate and value. Understanding these distinctions is essential for family lawyers advising clients with crypto holdings.

English courts now treat crypto assets as property. This means they can be included in the marital pot, made subject to freezing orders, and transferred under court order in family law proceedings.

The foundational case is AA v Persons Unknown [2019], where Bryan J applied the property criteria from National Provincial Bank v Ainsworth – definability, identifiability by third parties, capability of assumption, and permanence – and concluded that Bitcoin satisfies those tests. The court granted a proprietary injunction over 96 Bitcoins, treating them as property even though they do not fit neatly into the traditional categories of choses in possession or choses in action. 

More recently, Yuen v Li [2026] dealt with Bitcoin allegedly moved by one spouse during marital breakdown, illustrating that courts will apply property remedies, including conversion claims, to digital assets post-separation.

Because cryptocurrencies are considered property in England and Wales, they must be disclosed in financial remedy proceedings, valued, and can be transferred or sold under financial orders. The family court can issue orders regarding crypto assets, including property adjustment orders and freezing injunctions.

The Law Commission’s 2023 Final Report on Digital Assets recommended legislation to confirm a statutory “third category” of personal property, and the Property (Digital Assets etc) Act 2025 now provides that statutory backing. This gives family lawyers dealing with complex digital portfolios a firmer foundation for advice and court applications.

The court’s objective under the Matrimonial Causes Act 1973 is to achieve a fair outcome. In divorce, cryptocurrency is treated like other marital assets – it is assessed within the same framework as investments, savings and property. The court considers the length of the marriage, contributions made by each party, needs, standard of living, and overall resources.

Crypto acquired before marriage is generally considered non marital property, unless it has appreciated significantly during the marriage or has been mingled with matrimonial assets. However, even non-marital crypto must still be disclosed. The question of whether it should form part of the asset division process is separate, and the court retains discretion to take it into account to meet needs, especially after longer marriages.

When it comes to fair division of cryptocurrency, the court and the parties typically consider these options:

• Direct transfer of tokens from one spouse’s wallet to the other spouse’s wallet
• Sale and division, where crypto is liquidated to fiat currency and the proceeds split
• Offset, where one spouse retains the crypto holdings and the other spouse receives an equivalent value in other marital assets such as property equity or pension credits

A spouse may receive a larger share of traditional assets to offset the risk of retaining volatile cryptocurrency. Asset division may include both transferring crypto and liquidating it for fiat currency, depending on the nature and size of the portfolio.

Volatility and liquidity issues mean crypto is often treated more cautiously than cash in a financial settlement. The court may prefer to offset cryptocurrency against more stable other assets, particularly where one spouse has limited investment experience and the other spouse holds specialist knowledge of crypto markets. Property adjustment orders can require the transfer or sale of specific holdings, just as with any marital property.

Full and frank disclosure is a cornerstone of financial remedy work in family proceedings. This obligation applies equally to digital assets, traditional savings, and every other category of wealth. All cryptocurrency holdings must be disclosed in form e, including exchange accounts, digital wallets, DeFi positions and any yield or staking arrangements. Parties must provide full financial disclosure of all assets, including crypto. Failure to disclose crypto assets can reopen financial settlements long after they are finalised.

Bank statements and credit card records may reveal transfers to cryptocurrency exchanges, even where the underlying wallet addresses are not immediately known. Tax returns and exchange account histories can also flag crypto transactions. Public wallet addresses and transaction histories are required for asset disclosure, and where available, these can be cross-referenced against blockchain records.

In higher-value or contested cases, forensic accountants and blockchain analysts play a critical role. Forensic experts can trace digital wallet addresses and transactions, following the flow of assets across wallets and platforms. Blockchain technology makes crypto transactions traceable on a public ledger, but the pseudonymous nature of addresses means professional expertise is often needed to link them to a specific individual. Forensic experts can trace hidden cryptocurrency transactions even where mixers or privacy-enhancing tools have been used, though this adds cost and complexity.

Concealment risks in cryptocurrency are higher due to offline storage options like cold wallets, which are not connected to any exchange or online service. One spouse may store significant value on a hardware wallet or simply withhold seed phrases. Where the court concludes that a party has deliberately concealed hidden assets, it can draw adverse inferences – effectively assuming a higher level of assets than the non-disclosing party claims. Courts may draw adverse inferences for undisclosed cryptocurrency assets, and undisclosed crypto can result in adverse inferences during divorce. In serious cases, hiding cryptocurrency can lead to contempt of court charges, with serious consequences including fines or imprisonment. Costs orders can also follow.

The main challenge in divorce cryptocurrency cases is the volatility of crypto markets. Cryptocurrency values fluctuate significantly due to volatility, and what a portfolio is worth at the date of separation may be very different from its value at trial. Valuation of cryptocurrencies is complicated by market volatility, making accurate valuation essential but difficult.

Courts and family lawyers often agree a specific date for valuation – typically close to the final hearing or the date of a consent order. Valuation of cryptocurrency occurs at the date of the hearing, and courts may require multiple valuations of cryptocurrency during proceedings to ensure fair settlements. Valuation should occur at the date of the hearing or agreement, but if values vary significantly between key dates, the court has flexibility to revisit the figures.

Different types of digital assets may require different approaches:

Expert valuation may be necessary due to cryptocurrency volatility, particularly for substantial cryptocurrency holdings or complex portfolios. Exchange fees must be considered in cryptocurrency valuations, as they reduce the net amount available for fair distribution.

Practical methods for dividing cryptocurrency include:

• Transferring tokens directly between wallet addresses
• Liquidating to fiat currency and splitting proceeds
• Ring-fencing speculative or highly volatile crypto separately from more stable assets

Parties who accept large proportions of a settlement in cryptocurrency face ongoing market risk. Agreements should clearly record the basis of valuation and allocation to reduce later disputes. Expert evidence should be preserved and referenced in any consent order.

While the family court focuses on fairness, the tax treatment of disposing of or transferring crypto assets can materially affect outcomes. Capital gains tax liabilities can arise from transferring or selling cryptocurrency during divorce. Most disposals of cryptocurrencies are subject to capital gains tax, including selling for fiat, exchanging one token for another, or gifting tokens to a non-spouse.

Tax implications must be considered when dividing cryptocurrency in divorce. Transferring crypto to a spouse before the final order may qualify as a no-gain/no-loss transfer for CGT purposes, which can reduce tax liabilities. Timing matters: the rules for transfers between spouses after separation have been updated, and family lawyers should work closely with tax specialists on complex or high-value portfolios.

Income tax may also arise where crypto has been acquired through employment, mining or staking rewards. These are taxed under income tax rather than capital gains tax, and the distinction affects how the net value of holdings is calculated for the financial settlement.

Separating partners should seek tailored professional advice and tax guidance before finalising any settlement involving significant digital assets.

Proactive planning can significantly reduce disputes over cryptocurrency in future family proceedings. Prenuptial and postnuptial agreements can include bespoke clauses addressing how digital assets and crypto holdings are to be treated on separation, including valuation approaches and disclosure obligations. While such agreements are not automatically binding in England & Wales, they carry significant weight with the court where properly drafted with independent legal services for both parties.

Cohabitation agreements can also address crypto assets where unmarried partners are building digital wealth together. These provide clarity on ownership and fair distribution if the relationship ends, which is especially valuable given the difficulty of proving ownership of crypto held in private wallets.

Including digital assets in wills and lifetime planning is equally important. Executors or trustees need to be able to access wallets, seed phrases and exchange accounts lawfully and securely. Without clear records, crypto wealth can be effectively lost on death.

Keeping up-to-date records of crypto portfolios – platforms used, wallet addresses, approximate values and access details – supports both family law planning and estate administration. This is an area where professional advice from a family law specialist pays dividends.

Given the evolving nature of crypto markets and law, early input from a family law specialist familiar with digital assets is often crucial. The unique challenges of crypto – volatility, traceability, cross-border issues, and the risk of concealment – mean that generic legal assistance may not be sufficient.

Key scenarios where expert advice is particularly important include:

• High-value or complex crypto holdings across multiple wallets and platforms
• Suspected concealment of hidden assets in cold storage or on unregulated exchanges
• Cross-border assets or holdings on platforms outside England & Wales
• Cases where one spouse holds specialist knowledge and the other spouse does not

A family lawyer experienced in digital assets can assist you coordinate with forensic, valuation and tax experts, advise on appropriate court applications (such as interim orders or freezing orders), and help construct a fair, workable settlement structure. Legal assistance also helps parties understand court expectations around disclosure and behaviour concerning crypto assets during family proceedings, reducing the risk of sanctions.

Complex family situations benefit from early professional guidance. A family law specialist can advise you on the steps to take if your separation involves crypto assets. Professional legal assistance is especially important where there are concerns about your partner looking to dispose of assets. Getting it right from the start is far easier – and less costly – than unpicking mistakes later.

Do I Have To Disclose Cryptocurrency That I owned Before The Marriage?

Yes. In England & Wales, all assets – including pre-marital cryptocurrency and other digital assets – must be disclosed in divorce proceedings, regardless of when they were acquired. Parties must provide full financial disclosure, including crypto. The duty of disclosure is separate from the question of whether an asset should be shared. Pre-marital crypto is generally treated as non marital property, but the court retains discretion to take it into account to meet housing and income needs, particularly after longer marriages. Where pre-marital crypto holdings are substantial, expert advice is essential, as the court may still consider these assets when achieving a fair outcome.

What Can I Do If I suspect My Spouse Is Hiding Crypto Assets?

Start by raising your concerns with your family lawyer. Review bank statements and credit card records for transfers to cryptocurrency exchanges or purchases of crypto. Check any known devices or email accounts for exchange notifications, where lawful to do so. The court can order detailed disclosure, including from exchanges located in or cooperating with England & Wales, and may permit instructed experts to carry out forensic tracing of blockchain transactions. If the court concludes that a party has concealed crypto assets, it can infer higher asset levels, adjust the award in the other party’s favour, and make adverse costs orders.

Can The Court Make Orders Against A Crypto Exchange Based Overseas?

The English family court’s primary power is over the parties themselves. It will usually direct individuals to transfer or realise their own digital assets, even if held on overseas platforms. In some cases, orders or requests may be addressed to exchanges with a UK presence or those willing to cooperate, but enforcement against purely overseas entities can be more complex and may require separate proceedings. Where significant holdings sit on offshore cryptocurrency exchanges, early specialist advice on jurisdiction and enforcement is advisable.

What Happens If The Value Of Our Cryptocurrency Changes Dramatically During The Case?

Because of volatility, it is common to update valuations close to key hearings or before approving a consent order. Courts may require multiple valuations during proceedings to reflect material shifts. Parties can agree mechanisms in their settlement to deal with sudden changes – for example, percentage-based splits or rebalancing clauses if values move outside an agreed range before implementation. Taking advice on risk tolerance before agreeing to accept large portions of a settlement in cryptocurrency is strongly recommended.

Is It Safer To Receive Cash Instead Of Cryptocurrency In My Divorce Settlement?

Whether to take cash or crypto is a financial, risk-based decision. Cash provides certainty, while retaining crypto preserves exposure to potential gains and losses. Many parties prefer to offset volatile digital assets against more stable property, pensions or cash, especially where they have limited investment experience. Anyone considering accepting a significant share of a settlement in cryptocurrency should seek both legal and independent financial advice to understand the full implications. This does not constitute legal advice for your individual circumstances.
