Cryptoassets in Divorce: What Happens When Digital Wealth Goes Undisclosed?

Divorce is rarely straightforward. But as cryptocurrency has grown from a niche interest into a mainstream investment, it has introduced a new layer of complexity into financial proceedings — one that courts, legal professionals, and individuals are still getting to grips with.

The core issue is this: cryptoassets are uniquely easy to conceal. Unlike a savings account or a property, they leave no paper trail in the traditional sense. They can be held in private wallets, moved across borders in seconds, and stored in ways that are effectively invisible to someone who does not know where to look.

For anyone going through a divorce where they suspect their former partner holds cryptocurrency, this raises serious questions. And for anyone who holds crypto themselves, understanding their obligations is equally important.

It is also worth knowing that this issue does not disappear once a settlement is reached. If assets were concealed during proceedings, it may not be too late to do something about it — more on that below.

Your Legal Obligations: Full and Frank Disclosure

In England and Wales, both parties in divorce financial proceedings are legally required to provide full and frank disclosure of all their assets. Cryptoassets are included in that obligation.

Under the Matrimonial Causes Act 1973, the guiding principle is straightforward: full disclosure, regardless of how or where wealth is held. English courts have made clear that it makes no difference whether assets sit in a savings account or an encrypted wallet — if they exist, they must be declared.

Disclosure is made through a document called a Form E, a detailed financial statement completed at the start of proceedings. As Parachute Law notes, Form E does not currently have a dedicated section for digital assets, which means cryptocurrency must be listed under “other assets.” This gap means crypto is sometimes missed — or deliberately overlooked.

The legal framework varies in other jurisdictions, but the principle of financial transparency in divorce proceedings is broadly consistent across most legal systems. Wherever you are based, if you suspect a former partner is concealing digital assets, specialist tracing evidence can play a critical role in establishing the truth.

Why Cryptocurrency Is Particularly Easy to Hide

The appeal of cryptocurrency to someone looking to conceal assets is straightforward. Unlike a high street bank account or a property, it does not generate statements, letters, or easily recognisable paper trails. It exists across digital wallets, exchanges, and private keys — invisible, intangible, and, to the untrained eye, elusive.

In practice, this means a party going through divorce proceedings might understate the size of their holdings, claiming they are worth far less than they are. They might transfer funds to self-controlled wallets before or during proceedings, making them harder to locate. They might move assets through multiple exchanges or wallets to obscure the trail, or claim that assets have been lost, forgotten, or are simply inaccessible.

The decentralised nature of digital assets makes them inherently harder to locate, identify, and value than traditional assets. The volatility of cryptocurrency markets adds a further complication — values can fluctuate significantly between the preparation of an asset schedule and the day of a hearing, which creates its own scope for dispute.

What the Courts Have Said

The courts in England and Wales are increasingly aware of these challenges, and recent cases show they are taking non-disclosure very seriously.

In Culligan v Culligan [2025] EWFC 1, the court dealt with a £20 million Bitcoin fortune — originally purchased for £10,000 — alongside undeclared crypto holdings of £371,000 that were revealed mid-proceedings. The judge found this to constitute litigation misconduct, with serious consequences for the concealing party.

Courts have also demonstrated their willingness to impose significant sanctions for non-disclosure more broadly. In Brown v Brown [2024], persistent failure to provide financial documentation resulted in a 19-day custodial sentence. Beyond sanctions, courts retain the power to draw adverse inferences — effectively assuming that hidden assets exist and valuing them generously in favour of the compliant party.

The message is clear: concealment carries real consequences, and courts have both the tools and the appetite to pursue it.

The Role of Blockchain Tracing

Traditional forensic accounting — reviewing bank statements, company accounts, and paper records — is often insufficient when it comes to cryptoassets. Blockchain tracing is different.

Because every transaction on a blockchain is permanently recorded, a specialist investigator can follow the movement of funds across wallets and exchanges, even when significant effort has been made to obscure the trail. This is something the team at The Crypto Tracing Experts does regularly, and the results can be significant.

In a matrimonial context, blockchain tracing can help to identify wallet addresses and ownership patterns linked to a party, track historical transfers to establish what assets were held and when, determine whether assets remain under a party’s control or have been moved on, uncover attempts to dissipate funds ahead of or during proceedings, and produce a clear, evidence-based report that can be presented in court.

Courts are increasingly reliant on forensic investigators and digital asset specialists, who play a valuable role in identifying undeclared holdings, analysing blockchain activity, and providing evidence — often on a single joint expert basis.

It is worth being honest about the limits, too. Where assets have been moved into privacy-focused cryptocurrencies or through highly complex chains, tracing can become more challenging — though not always impossible. Understanding what is and is not traceable is something we can help you assess from the outset.

Already Divorced? It May Not Be Too Late

One of the most important things to understand about concealed cryptoassets is that the issue does not necessarily end when a settlement is signed.

In England and Wales, a court has the power to set aside a financial remedy order if it was obtained by fraud or material non-disclosure. This principle was confirmed by the Supreme Court in Sharland v Sharland [2015], which established that a consent order obtained through fraudulent non-disclosure can be revisited — even years after it was made.

For cases involving cryptocurrency, this matters enormously. Blockchain forensics can establish not just where assets are now, but where they were in the past — including at the time of proceedings. If a former partner held, controlled, or had access to cryptocurrency that was never declared, the on-chain record may still be there to find.

If you settled your divorce some time ago and suspect that digital assets were concealed from you, it is worth speaking to a qualified family law solicitor about whether grounds exist to reopen the case. If they do, expert tracing evidence could be central to what comes next. Get in touch with our team, and we can talk you through what may be possible.

The Changing Legal Landscape

The law in this area is actively evolving. Following the Law Commission’s work on digital assets, the proposed Property (Digital Assets etc) Bill will formally recognise crypto as a distinct form of property under English law. For family lawyers, this is significant — it confirms that digital assets can be the subject of disclosure, valuation, and enforcement orders in the same way as traditional property, and may prompt updates to standard disclosure forms.

Wherever you are in the world, the direction of travel is the same: regulators and courts are taking cryptoassets increasingly seriously, and the expectation of full disclosure is only going to grow.

What to Do If You Suspect Hidden Crypto Assets

If you believe a former partner may be concealing cryptocurrency, there are practical steps you can take — but this is not an area to navigate alone. You will need qualified legal advice from a family law solicitor in your jurisdiction.

Courts can order a party to disclose specific information, including wallet addresses and exchange account statements. They can also make orders against third parties, such as cryptocurrency exchanges, to provide transaction records. Where there is a risk that assets may be moved or dissipated, a freezing injunction can be sought — though given how quickly cryptocurrency can be transferred, acting quickly is critical.

Specialist blockchain tracing, carried out alongside legal proceedings, can provide the evidence needed to support these applications and challenge incomplete or misleading disclosure.

A Note If You Hold Cryptocurrency Yourself

If you hold cryptoassets and are going through divorce proceedings, you are legally required to disclose them. The courts are increasingly knowledgeable in this area, and the consequences of non-disclosure — from costs orders and adverse inferences to contempt proceedings and the reopening of settled cases — are serious and long-lasting.

If you have questions about how to value or disclose your holdings accurately, speak to a family law solicitor. Getting this right from the start is far simpler than dealing with the consequences of getting it wrong.
