What Happens to Crypto Held in a Custodial Account After Death?
When someone dies, most of what they owned follows a familiar legal path through an estate. A custodial cryptocurrency account — one where a platform, not the individual, holds the actual keys — follows a similar path in theory, but the process of proving who’s entitled to the assets tends to be more paperwork-heavy than families expect.
The short answer
Custodial platforms generally don’t transfer crypto automatically when a customer dies; they wait for someone to open a claim. That usually means submitting a certified death certificate along with documents establishing legal authority, such as letters testamentary from a probate court or, for smaller estates, a simplified affidavit. Once the platform verifies the paperwork, it typically transfers the holdings to the estate, to a named beneficiary, or liquidates and disburses the proceeds, depending on the account’s setup and the platform’s own policies.
Why this differs from a self-custodied wallet
The key distinction is who holds the private keys. In a custodial account, the platform controls access, which means it can verify a claim through its own compliance process and release funds once satisfied — much like closing a bank account after a death. A hardware wallet with an unknown PIN, by contrast, has no company to call; if no one has the access information, the assets can become permanently unreachable regardless of what a will says. Custody status should be one of the first things an executor identifies when crypto shows up among a person’s records.
What documentation platforms tend to require
- A certified death certificate. Nearly every platform requires an official copy, not a photocopy or scan alone, before opening any conversation about the account.
- Proof of legal authority. This is usually letters testamentary, letters of administration, or a small-estate affidavit, depending on state probate rules and account size.
- Identity verification for the claimant. The person filing the claim typically has to pass the same identity checks a new customer would, even when acting on behalf of an estate.
- Beneficiary designation, if one exists. Some platforms allow a named beneficiary on the account, which can shorten the process considerably compared with going through a full estate claim.
Where things commonly stall
Crypto platforms don’t always have a dedicated deceased-account team the way large banks do, and support queues can be slow. It also isn’t unusual for an executor to not know an account exists at all until they find a statement, an app, or a note among the decedent’s records, and even after a claim opens, proving ownership without physical certificates can add another layer of back-and-forth. Because there’s no universal registry of who holds crypto where, unlike the way real estate or bank accounts are tied to public or institutional records, an account that no one mentions to the executor may simply go unclaimed. That risk is a strong argument for documenting account locations somewhere an executor can find them, separate from any password or key itself.
Tax and valuation considerations
Crypto held at death is generally included in the estate’s value at its fair market value on the date of death, and heirs typically receive a stepped-up cost basis, though the specifics depend on state law, the size of the estate, and how the asset is treated for tax purposes generally. Rules around estate and inheritance taxation change and vary by circumstance, so this is an area where an estate attorney or tax professional familiar with digital assets is worth involving early, rather than after a claim is already underway.
What to weigh
A custodial account isn’t lost the moment its owner dies, but it also isn’t handled automatically the way a jointly titled bank account might be. The process depends heavily on the specific platform’s policies, the paperwork the estate can produce, and whether anyone even knows the account exists. Planning ahead — noting where accounts are held and whether a beneficiary designation is available — tends to matter more for crypto than for most other assets, precisely because there’s no fallback system to catch what goes unmentioned.
The takeaway
Treat a custodial crypto account like any other financial account that needs to be disclosed to an executor: write down where it’s held, and check whether the platform offers a beneficiary designation now, while it’s simple to add one, rather than leaving a probate claim as the only option later.
