Cryptocurrency and UK Estates: When Executors Can’t Access Digital Wealth

As the adoption of cryptocurrency grows in the UK, legal issues involving digital assets are turning up in estate administration and, increasingly, in the courts. Executors are often unable to access cryptocurrency held by a deceased person, leading to lost assets and tricky legal questions.

The Nature of the Problem

Cryptocurrency, unlike conventional assets, is only accessible with private keys or recovery phrases. If these aren’t left behind—or are misplaced—the assets can be lost for good. This issue has surfaced in several estate cases across England and Wales.

A Recent Example: The Estate of Mr. X

In one notable estate administration (details anonymised for privacy):

• The deceased owned significant amounts of Bitcoin, held in personal wallets and possibly on exchanges.
• The will mentioned these assets, but no passwords, keys, or recovery instructions were provided.
• Executors searched the deceased’s home, belongings, computers, and cloud accounts, but found no clues.
• Attempts to contact exchanges were unsuccessful, as they required account access or further authentication.
• As a result, the Bitcoin could not be recovered—despite being clearly part of the estate and listed in probate.

Legal Outcome

In these UK cases, the High Court has confirmed:

• Cryptocurrency forms part of the estate just like any other property, as established in AA v Persons Unknown [2019] and Re: Ion Science Ltd v Persons Unknown [2020], where Bitcoin was recognised as property.
• However, without access credentials, the executor is legally required to report the asset as part of the estate, disclose the efforts made to recover it, and accept that it cannot be distributed.

No established precedent obliges the government or exchanges to help further, since cryptocurrencies are decentralised. The asset is considered lost unless credentials surface later.

What does this mean for Executors?

• Executors have a duty to diligently search for access information and document efforts for the probate court.
• Lost assets still need to be disclosed. Even if cryptocurrency cannot be reached, it must be listed in probate and estate accounts.
• No forced access. The courts cannot mandate recovery if technical access is impossible.

Advice for Estate Planning when Cryptocurrency forms part of the estate

• Always leave clear, secure instructions for accessing cryptocurrency—with an executor or trusted adviser, not only in the will.
• Regularly update access details for digital wallets and exchanges.
• Work with legal professionals who understand digital assets.

Conclusion

The rise of cryptocurrency means UK estates increasingly include valuable, but potentially inaccessible, digital assets. While the law recognises crypto as property, technology limitations can defeat even the most diligent executor. Thoughtful digital legacy planning is vital—without it, wealth may be forever out of reach.
