What Estate Planning Documents Should Reference Crypto Holdings?
Traditional estate planning assumes a bank or brokerage will eventually notice an account holder has died and cooperate with the estate. Crypto doesn’t work that way, and that difference is exactly why estate documents need to treat it differently.
The short answer
A will or trust should identify that crypto holdings exist and name an executor or trustee with authority over them, while a separate, securely stored document should hold the actual access details — private keys, seed phrases, or platform logins — needed to reach the assets. Keeping access information out of the public probate record while still ensuring an authorized person can find it is the core balancing act.
Why crypto breaks the usual estate assumptions
When someone dies owning a bank account, the institution can generally be notified and will work with the estate through a known legal process. Crypto has no equivalent institution in the case of self-custodied holdings — there’s no company to call, no customer service line, and no way to reset a lost password. If nobody knows an asset exists, or if the person who does know dies without leaving usable access information, the crypto can become permanently unreachable. This is a much sharper version of the same problem discussed in how households can back up wallet access information safely, except in an estate context the stakes are permanent rather than merely inconvenient.
Documents that typically come into play
- The will or trust. This should reference that digital assets exist and grant the executor or trustee explicit authority to manage and access them, since some platforms and legal frameworks require that authority to be spelled out rather than assumed.
- A letter of instruction or digital asset memorandum. Many estate planning attorneys recommend a separate, updatable document listing what exists — which platforms, which wallets, roughly what’s held — without embedding sensitive access credentials directly into the will itself, since a will often becomes a public record during probate.
- A secure access record. Seed phrases, private keys, and login credentials are generally best kept in a secure, separate location — such as a safe deposit box or a reputable password manager with designated emergency access — with instructions in the estate documents pointing the executor toward where to find it, rather than the credentials themselves being written into the will.
Why the split between “what exists” and “how to access it” matters
Putting sensitive key information directly into a will risks exposing it publicly once probate begins, since wills often become accessible court records. Keeping it entirely private, on the other hand, risks the information being lost or never found. Separating the two — a public-facing reference that assets exist, paired with a private, securely stored access mechanism — is a common way estate professionals try to solve both problems at once.
Custodial accounts versus self-custody
If crypto is held through a platform rather than in self-custody, the process can look more like a traditional account, since the platform may have its own procedure for verifying a death and transferring or liquidating the holdings for the estate. This is a similar underlying question to who controls crypto in a custodial account until adulthood, in that authority and access don’t automatically transfer just because a person is entitled to the assets. Self-custodied crypto has no such fallback, which is part of why insuring self-custodied crypto is so difficult in general — there’s no institution standing behind it if something goes wrong, including the original owner’s death.
What to weigh
- Keep the list current. Crypto holdings and access methods change more often than many other assets, so a memorandum that’s a few years old may already be outdated, similar to how organizing crypto records alongside bank statements only stays useful if it’s updated as holdings change.
- Name someone who understands crypto, or make sure instructions are detailed enough that a less technical executor could still follow them.
- Work with an estate planning attorney familiar with digital assets, since the legal treatment of authority over crypto varies and continues to evolve.
The bottom line
Crypto’s lack of a central institution means the usual assumption that an asset will eventually surface during probate simply doesn’t hold. Clear references in a will or trust, paired with securely stored access details maintained separately, are what stand between crypto holdings being passed on as intended and being lost permanently when their owner dies.
