Common Questions I Get About Cryptocurrency in Divorce Cases Answered

In recent years, I’ve noticed cryptocurrency and digital assets coming up more frequently in cases I work on. What used to be mentioned only rarely — say one in 20+ cases — is now much more of a common occurrence as it continues to grow in popularity. 

Solicitors handling these cases usually have the same core questions: how do we find it, how do we value it, what happens if it was bought before the marriage, how to know if the spouse is hiding it, etc. 

Here’s my response to some of the most common cryptocurrency divorce questions I receive.

What Happens to Cryptocurrency Bought Before Marriage?

The starting position for cryptocurrency bought before marriage is straightforward: Assets acquired before marriage are viewed as non-matrimonial. So if somebody bought £5000 of Bitcoin in the week prior to marriage, that £5000 asset is still technically theirs. However, just because you bought it pre-marriage, doesn’t mean you get to keep the earnings if you sell it. 

The aspect of this process where forensic accounting becomes essential is when you consider the appreciation of the asset during the marriage — this amount is viewed very differently to the original outlay. Courts will look at whether the increase in value was passive (the market went up) or active (the spouse traded, managed, or reinvested during the marriage to build value) to determine what extent of the appreciation is a marital asset. Crucially, they will also consider how long the marriage lasted and whether there are sufficient assets elsewhere in the settlement to meet the needs of both parties. 

The co-mingling of assets matters. I’ve worked on cases where pre-marriage assets, like Bitcoin holdings, became so intertwined with joint finances over the course of the marriage that the court treated them as matrimonial property. So if you’ve used joint funds to buy additional cryptocurrency, or if you’ve moved pre-marriage holdings into a wallet even part-funded by marital income, you’ve likely matrimonialised your assets. 

The forensic work here is detailed and highly complex. I will examine wallet transaction histories, exchange records, and bank statements in order to determine when funds entered the wallet, where they originated from, and how the asset was managed during the marriage. 

How do you Value Cryptocurrency When the Price Changes Daily?

This is the question that causes the most practical difficulties. Traditional assets (property, pensions, and even shares) all have relatively stable values over the timescale necessary for divorce proceedings to be concluded. Cryptocurrency, on the other hand, doesn’t. 

Bitcoin can swing 30% in value between the date of the Form E and the final hearing. Such large swings aren’t unheard of, in fact they’re relatively common in crypto markets. But if you’re looking to divide assets and one party is receiving Bitcoin worth £100,000 pre-fall, a 30% drop means that they’ll actually receive £70,000, a £30,000 decrease over the course of a few weeks/months. 

The valuation method I use for cryptocurrency in divorce will depend on the specific circumstances involved. For more straightforward cases, I will value the holdings on a specific date — typically the date of the final settlement or the date closest to the hearing — but for more volatile situations, I’ll calculate an average value across a defined period (usually 30 or 90 days). This is intended to smooth out any short-term price swings. 

Both approaches are acceptable. The key is that both parties and their solicitors can agree on one method before we begin in order to avoid disputes about which number is used when settlement discussions begin. 

Tax implications complicate this further. Transferring or selling cryptocurrency can trigger Capital Gains Tax. If a spouse receives £100,000 of Bitcoin in a settlement and immediately sells it, they may face a substantial tax bill. 

Can Spouses Hide Cryptocurrency in Divorce Proceedings?

Yes, they can try. The pseudonymous nature of blockchain transactions makes it easier to hide than traditional bank accounts. But it’s not as untraceable as people think.

The duty of full and frank disclosure applies to cryptocurrency just as it does to any other asset. If a spouse fails to disclose crypto holdings and it’s discovered later, the court can set aside the financial order, award a greater share of other assets to the ‘honest’ spouse, and impose cost penalties.

The process of tracing hidden cryptocurrency requires examination of bank statements, since cryptocurrency won’t simply materialise out of nowhere — it’s purchased with fiat currency through an exchange (Coinbase, Kraken, Binance, etc.). Any transfers from bank accounts to such platforms will show up clearly in transaction histories. 

If evidence of crypto purchases is identified, I can determine which exchanges were used and analyse available account and transaction data. Where additional disclosure is required, I support solicitors in identifying the information needed from exchanges. Blockchain analysis tools allow me to trace transactions between wallets, even where funds have been moved multiple times to obscure the trail.

The blockchain is a public ledger and every transaction is recorded permanently. If I have a wallet address, I can see every transaction that wallet has ever made — when funds came in, when they went out, and where they went. It’s more difficult to hide digital assets than people realise, and the penalties for trying are severe.

Cryptocurrency isn’t the only asset spouses try to hide. Read about other hidden asset types here.

How is Cryptocurrency Divided in Divorce Settlements?

There are three main methods, and the right approach depends on the circumstances of the case.

1. Direct Transfer: If both parties are comfortable with cryptocurrency, holdings can be transferred from one wallet to another. This requires cooperation — you need the private keys or access credentials — but it’s technically straightforward. The advantage is that no sale is required, so there’s no immediate tax liability.
2. Offsetting: One spouse keeps the cryptocurrency, and the other receives a greater share of traditional assets to balance the settlement. This works well when one party wants nothing to do with crypto and the other wants to retain the holdings. The valuation becomes critical here because you’re trading a volatile asset for a stable one.
3. Liquidation: The cryptocurrency is sold, converted to pounds sterling, and the cash proceeds are divided. This eliminates valuation arguments (you’re dividing actual money) and ensures both parties receive a stable, usable asset. The downside is the immediate tax liability and the timing risk — if the market drops between the decision to sell and the actual sale, both parties lose value.

I’ve seen all three methods used successfully. The choice depends on the cryptocurrency/digital asset knowledge and fluency of both parties, their willingness to retain crypto exposure, the size of the holding relative to other assets, and the urgency of the settlement.

When do Solicitors Need to Instruct a Forensic Accountant for Crypto Cases?

Not every divorce involving cryptocurrency requires a forensic accountant, but several situations do. Examples of common scenarios I find that solicitors may require support from a forensic specialist include: 

1. Suspected Hidden Holdings: If there’s evidence of crypto purchases in bank statements, but no disclosure of current holdings, you need someone who can trace those funds and establish what exists now.
2. Large/Complex Holdings: If cryptocurrency represents a significant portion of the marital estate — say, more than £50,000 — accurate valuation and expert evidence become important. Courts expect detailed, supportable valuations for substantial assets.
3. Active Trading: If one spouse has been actively buying, selling, and trading cryptocurrency throughout the marriage, the transaction history can be extremely complex. Establishing what was bought with matrimonial funds, what gains or losses occurred, and what the current position is requires in-depth forensic analysis.
4. Disagreement Over Value/Division Method: If the parties can’t agree on how to value holdings, or which date to use, expert evidence from a forensic accountant can provide the court with a clear, impartial assessment.

The earlier you involve forensic accounting expertise, the better. Cryptocurrency evidence can be lost — exchanges delete old records, wallets are forgotten, transaction histories become harder to reconstruct. Early instruction means I can secure the evidence while it’s still available and provide solicitors with a clear picture of what exists before settlement negotiations begin.
