What happens to your crypto when you die, and how do families plan for access?

The core problem

With most traditional assets, an executor can produce a grant of authority and an institution will act. Digital assets held in self-custody work differently. Control follows the private key. If the key is lost, there is no administrator to appeal to and no recovery process. The asset continues to exist on the ledger and simply becomes unreachable.

This is why planning for digital assets has a dimension that conventional estate planning does not. It is not enough to say who should inherit. Somebody has to be able to actually take control.

Why a will alone is often not enough

A will can direct who inherits an asset. It cannot, by itself, deliver access. There is also a specific trap. In many jurisdictions a will becomes a public document once it is admitted to probate. Writing a seed phrase or private key into a will could therefore expose it to anyone who cares to look, and would put the assets at immediate risk.

The general practice, which should be confirmed with a qualified lawyer in the relevant jurisdiction, is to keep the legal instrument and the access mechanism separate. The will or trust deals with entitlement. A separate, secure process deals with access.

Approaches families use

A secure memorandum is the most common starting point. This is a document, kept outside the will, that records what assets exist, where they are held, and how a fiduciary or heir can begin the process of reaching them. It is typically stored with a lawyer, in a safe deposit arrangement, or with a specialist provider, and it is referenced by the will without its contents being disclosed.

Multi-signature arrangements are also widely used. Rather than a single key controlling the assets, several keys are required, and they can be distributed between the owner, a trusted family member and a professional. This removes the single point of failure and can allow a controlled handover without any one person holding everything during the owner's lifetime.

Qualified or institutional custody is the third route. Here the assets are held by a regulated custodian, and succession is handled through the custodian's own processes, which look much more like those of a traditional financial institution. That is often attractive precisely because executors and advisers already understand how to deal with it.

Where structures fit

Trusts, foundations and insurance based structures such as PPLI can sit above these arrangements. Where assets are held inside a structure with a professional custodian, the succession question is partly answered by the structure itself: the structure continues to exist, the custodian continues to hold the assets, and the terms of the structure determine who benefits. Whether that is available and effective depends on the jurisdiction and on the carrier or trustee involved.

Questions worth raising with your own advisers

Useful questions include: if I were unavailable tomorrow, could the right people identify what I hold? Could they reach it, lawfully and safely, without that information being exposed while I am alive? Who is the fiduciary, and are they able and willing to handle digital assets? Does my will refer correctly to the access process without containing it? When was this last reviewed against what I actually hold today?
