The Practical Challenges of Cryptocurrency in Divorce Proceedings

Cryptocurrency sits awkwardly within financial remedy proceedings. Not because courts lack the power to deal with it, but because the asset itself resists the standard disclosure mechanisms that the process relies on. Here is where the difficulty actually lies.

Bitcoin increased in value by 125% during 2024. The global crypto market is valued at around $3 trillion. Around 12% of UK adults hold some form of digital asset, according to the Financial Conduct Authority. These are not marginal figures, and they explain why cryptocurrency is appearing with increasing frequency in financial remedy cases — particularly in high-net-worth matters and among younger couples who have been investing in digital assets for years before marriage.

Understanding where the genuine difficulty lies helps practitioners structure their approach and helps clients understand why certain steps are necessary.

Volatility: An Asset That Refuses to Stand Still

No asset commonly seen in financial remedy proceedings moves the way cryptocurrency does. A portfolio worth £80,000 at the date of a First Directions Appointment can be worth £130,000 or £50,000 at the Financial Dispute Resolution hearing, without either party having done anything. In May 2021, the global crypto market fell by more than £1 trillion in a matter of weeks. Practitioners specialising in this area have reported seeing values fluctuate by as much as 30% between the time a schedule of assets is prepared and the day of a hearing itself, with direct implications for settlement negotiations.

Two approaches are seen in practice. Snapshot valuation fixes the value at a specific procedural point, giving certainty but leaving one party exposed to price movements after the order is made. Percentage transfer, where the court orders a proportion of the holding itself rather than a cash equivalent, distributes that risk between both parties. Where one party is retaining a crypto portfolio offset against other assets, an agreed and current valuation is essential. Whatever approach is taken, courts need independently produced valuations, not balance screenshots taken on a phone.

Disclosure: No Third Party Holds the Record

For most financial assets, the disclosure process has a structural check built in. A bank produces statements whether or not the account holder wants it to. A pension scheme provides a cash equivalent transfer value. An employer confirms share option vesting. The third-party record exists independently of the person being asked to disclose.

Cryptocurrency held in a self-custody wallet has none of this. There is no institution maintaining parallel records. No statement is generated automatically. The entire burden of disclosure sits on the honesty of the person completing the financial disclosure form. To make things harder, some exchanges provide downloadable monthly statements (Coinbase is one example), while others only permit export of transaction history on request, and others require that history to be specifically applied for in advance. A practitioner who simply accepts whatever documentation is offered may be working from an incomplete picture without knowing it.

Indicators that disclosure may be incomplete include exchange payments on bank statements, references to hardware wallet devices, subscriptions to portfolio or tax software such as Koinly, CoinTracker or TaxBit, and lifestyle expenditure that cannot be accounted for by declared income.

The Range of Assets: Beyond Bitcoin

Bitcoin and Ethereum trade on liquid global markets and can be valued at any given moment with reasonable reliability. A significant proportion of what people actually hold is more complicated.

• Altcoins with limited trading volumes may have quoted prices that bear little relation to what could realistically be achieved on a sale
• NFTs present a particular problem: a non-fungible token cannot be split between parties the way fungible crypto can, and its value is simply what a willing buyer will pay on the day. Significant caution is warranted when offsetting NFT holdings against more stable assets
• Staking positions and liquidity pools in decentralised finance carry restrictions on withdrawal and involve mechanisms such as impermanent loss that materially affect value
• Token vesting schedules may mean assets exist in principle but cannot be accessed for a defined period

Getting this wrong affects the accuracy of the matrimonial pot. The question a practitioner should ask is whether the forensic expert being considered has actually worked with DeFi positions and NFT valuations, not simply with Bitcoin.

Enforcement: The Private Key Problem

A court can order the transfer of cryptocurrency. It cannot compel that transfer mechanically. A self-custody wallet is only accessible to the person holding its private key — essentially a unique sequence of characters that functions as the wallet’s password. If that person refuses to cooperate, the asset does not move.

The available tools include sequestration of equivalent assets elsewhere in the estate, contempt proceedings, and adverse inference orders. A freezing injunction under Section 37 of the Matrimonial Causes Act 1973 can prevent further movement of assets during proceedings, but the forensic evidence base to support that application needs to be in place before it is made. Enforcement planning cannot start after a transfer order is ignored.

The Difficulty of Disproving What Is Not There

One challenge that is less often discussed sits with the party accused of concealment rather than the accuser. Where one spouse alleges the other holds undisclosed cryptocurrency, the accused party faces a near-impossible task: evidencing the non-existence of alleged assets. They cannot produce a statement showing an account is empty if the alleged account is one they say they do not have.

This asymmetry can make cases significantly more expensive and contested than either party anticipated. A forensic investigation that is thorough, methodologically sound, and court-compliant is in the interests of both sides, because it replaces speculation with evidence.

Frequently Asked Questions

How do courts handle crypto volatility in divorce?

Courts typically use either a snapshot valuation fixed at a specific date near the hearing, or a percentage transfer of the actual holding, which distributes the volatility risk between both parties.

Can a spouse hide cryptocurrency by using a self-custody wallet?

Self-custody wallets have no automatic statements or third-party records. However, forensic blockchain analysis can trace transactions on the public ledger, and indicators such as exchange payments on bank statements often reveal undisclosed holdings.

Are NFTs treated differently from Bitcoin in divorce?

Yes. An NFT cannot be split between parties. Courts typically order a sale, a full transfer, or an offset against other assets. Specialist valuation is needed because NFT prices can be highly volatile and illiquid.

What happens if someone refuses to hand over crypto after a court order?

The court can sequester equivalent assets, make costs orders, initiate contempt proceedings, or adjust the remainder of the settlement. Enforcement planning should begin before a transfer order is made.
