Cryptocurrency and Will disputes: navigating the new frontier of estate planning

When a loved one passes away, grief is often accompanied by logistical challenges. But in today’s digital age, what if those challenges include a digital scavenger hunt for hidden cryptocurrency?

With crypto adoption rising across all age groups in Australia, more families are facing this unexpected and often frustrating legal reality. Traditional estate planning frameworks haven’t yet caught up with the complexities of digital assets, leaving gaps that can result in legal disputes, delays, and permanent financial loss.

Cryptocurrency and estates: what recent reporting reveals

Recent reporting by the Australian Financial Review underscores just how common, and how costly, cryptocurrency estate issues have become.

The AFR highlighted cases where families were aware a loved one held crypto, but had no clear records of what assets existed, where they were stored, or how to access them. In one example, cryptocurrency educator Sydel Sierra assisted a family in recovering digital assets worth around $30,000 after the deceased left behind fragmented clues but no clear instructions.

The AFR also noted that Australians aged 65 and over are now the fastest‑growing group of crypto adopters, a shift that has caught many estate plans and families unprepared.

We shared with the AFR that Australian courts are beginning to see a clear pattern of disputes emerging from these gaps, often with significant financial consequences.

What makes Cryptocurrency different in estate planning?

Unlike traditional assets such as property, shares, or bank accounts, cryptocurrency presents unique challenges that frequently sit at the centre of inheritance disputes:

• Technical complexity: crypto assets are secured by private keys. If these keys are lost, they are virtually impossible to recover, potentially leaving executors locked out permanently, as there is usually no recovery mechanism.
• Self‑custody risks: many investors control their assets directly, without a bank or intermediary that can reset access.
• Jurisdictional hurdles: assets may be held on international exchanges or in private wallets, complicating questions of legal jurisdiction and applicable laws.
• Privacy and visibility: the pseudonymous nature of crypto can make assets difficult to identify and track, increasing the risk of hidden holdings and family disputes.

Common cryptocurrency Will disputes emerging in Australia

As outlined in the AFR, and reflected in disputes we are now seeing, cryptocurrency estate conflicts typically fall into three categories:

• Lost key disputes: beneficiaries know the deceased held crypto, but without the private key or wallet password, the assets can’t be recovered.
• Hidden asset claims: families suspect undisclosed crypto holdings but can’t find evidence, often leading to accusations of concealment or misappropriation.
• Exchange vs. private wallet access issues: executors face very different recovery processes depending on whether assets are held on a centralised exchange or in a private wallet. Immediate steps to take if a loved one may have held cryptocurrency

If you believe the deceased held crypto assets, early action matters:

• Secure all devices: safeguard computers, phones, and storage devices that may contain private keys or login credentials.
• Search for records: look for written notes, password manager entries, or safe deposit boxes that may contain access information.
• Identify platforms: evidence of an Australian‑based exchange account may allow executors to recover assets using probate documentation.
• Seek advice early: legal and technical guidance can prevent missteps that compromise recovery.

Planning ahead: avoiding cryptocurrency estate disputes

AFR reporting reinforces what we see in practice: most crypto disputes are avoidable with proper planning. Key steps include:

• Clear identification of assets: note that you own digital assets and where records of them can be found, without including sensitive access details.
• Separate access instructions: never place private keys or passwords directly in your Will, which becomes a public document.
• Consider a digital executor: appoint a trusted, technically capable person to assist your executor where appropriate.
• Professional advice: volatility, tax consequences, and access risks mean crypto requires professional estate planning.

The future of cryptocurrency estate planning

As cryptocurrency becomes more mainstream, legal frameworks and technologies will continue to evolve. But for now, the burden falls on individuals to plan carefully.

Without clear instructions, cryptocurrency can remain permanently locked on a blockchain, beyond the reach of loved ones. With informed legal advice, however, these assets can be protected, transferred, and managed responsibly.
