Crypto must be disclosed in UK divorce proceedings like any other asset — and courts can freeze it, order exchanges to reveal it, and punish spouses who hide it. How digital assets are found, valued and divided.
Important Risk Warning
This is not financial advice. Cryptocurrency investments are highly volatile. The value of your investment can go down as well as up, and you could lose all the money you invest. Don't invest unless you're prepared to lose all the money you put in.
London — Family lawyers will tell you the question arrives in almost every consultation now, usually in the same nervous phrasing: "I think my ex has crypto. Can they just... not mention it?"
They can try. People do, every week, on the theory that coins in a self-custody wallet are invisible to courts in a way a NatWest account isn't. The theory is wrong, and the consequences of testing it are worse than most people hiding assets seem to realise.
Yes, fully. Financial proceedings under the Matrimonial Causes Act 1973 require both parties to give full and frank disclosure of everything they own, and cryptoassets are property — a position now backed by statute, since the Property (Digital Assets etc) Act 2025 confirmed that digital assets can be objects of personal property rights in English law.
The standard disclosure form, Form E, doesn't yet have a dedicated box for digital assets, which means crypto gets listed alongside other assets rather than prompted for by name. That's a genuine gap — it makes honest disclosure rely on the discloser knowing the rules — but it doesn't change the obligation. Leaving your bitcoin off Form E is non-disclosure, the same as leaving off a flat in Marbella.
Less mysteriously than you'd think. The starting point is nearly always the bank statements that have to be disclosed anyway: transfers to Coinbase, Kraken or Revolut sit right there in the transaction history, and a £40,000 outflow to an exchange three years ago with nothing coming back is the kind of loose thread judges notice.
From there, the toolkit escalates. Forensic investigators trace wallet addresses and analyse blockchain transaction histories — the public ledger that makes crypto pseudonymous rather than anonymous cuts both ways. Courts can order disclosure from cryptocurrency exchanges directly. Devices can be examined. And where there's a real risk of assets being moved mid-proceedings, a freezing order can lock things down.
Worth adding: HMRC now receives UK exchange data automatically under the CARF reporting framework. The paper trail around crypto in 2026 is thicker than it has ever been, and divorce proceedings are exactly where such trails get pulled on.
The court doesn't need to find the coins to punish the concealment. Where a judge concludes someone has hidden assets, they can draw adverse inferences — effectively assuming the hidden wealth exists and adjusting the settlement against the non-discloser. A spouse caught concealing can come out with a worse deal than honest disclosure would ever have produced.
And settlements built on non-disclosure aren't safe even after the ink dries. If hidden crypto surfaces years later, the deceived party can apply to reopen the financial order. Bitcoin bought quietly in 2019 and "forgotten" in 2024 proceedings is a liability with no expiry date.
This is the genuinely awkward part, and it's not about dishonesty — it's volatility. A holding worth £80,000 at the date of disclosure might be £55,000 or £110,000 by the final hearing. Courts work with valuations at agreed dates and sometimes revisit them, but there's no perfect answer; one side usually carries the price risk for some window.
Division itself takes one of three shapes in practice. The crypto is sold and the sterling split — cleanest, though it crystallises capital gains tax, which needs factoring into the maths. One party keeps the crypto and the other takes offsetting assets, which means arguing about what the volatile thing is "really" worth. Or, more rarely, the holding is transferred in kind between spouses — and transfers between separating spouses have their own CGT timing rules that reward getting advice before, not after.
Suspecting a spouse has crypto? Don't play detective with their devices, which can backfire legally; tell your solicitor early, because bank statements plus a forensic specialist find most of what exists, and freezing orders work best before assets move.
Holding crypto yourself? Disclose it, all of it, with records of what you bought and when. The annual exempt amount for CGT is £3,000, the courts treat your wallet exactly like your current account, and the one strategy with a genuinely terrible track record in English family courts is hoping nobody asks.
