Keeping legal documents and keys apart

The first idea most people have about crypto inheritance is to write the seed phrase into the will. It looks sensible. It is a design to avoid, and the reason lies in the path a legal document travels.

After death, a will goes through procedures in which its contents are confirmed, and in the course of those procedures heirs and other parties may read it. Documents can also be mislaid or reach a third party while in storage. A seed phrase lets whoever sees it move the assets that same day. Writing one in creates, by your own hand, the possibility that what should have passed to a beneficiary is taken en route.

So split the design into two layers. The legal document expresses intention: these crypto assets exist, and this is who should receive them. The keys are handled by a separate arrangement that conveys where they are stored and how they are opened. Succession only works when both halves are in place.

The two forms of holding also differ in practice. Assets at an exchange are generally treated as a claim against the company, and go through that operator's own inheritance procedure, with documents and steps that vary by operator. Assets in a self-custody wallet come down entirely to whether anyone can reach the key. The same phrase — inheriting crypto — describes two quite different exercises.

Beyond this point the questions belong to professionals: what form of document is effective, how it should be held, how to divide assets among several heirs, how the holdings are valued for tax. All of these follow rules set by law, and the law is amended. This page does not assert forms or requirements. The sums tend to be large and mistakes cannot be undone, so consult a lawyer, tax accountant and judicial scrivener familiar with both inheritance and crypto assets.
