What Legal Authority Does an Executor Need to Sell Cryptocurrency From an Estate?
Settling an estate that includes cryptocurrency raises a question that rarely comes up with a bank account: how does an executor prove, to a platform that has never met them, that they have the legal right to move someone else’s assets.
The short answer
An executor generally needs formal, court-issued documentation — most commonly letters testamentary, or letters of administration when there is no will — before selling cryptocurrency that belonged to a deceased person’s estate. This paperwork, granted through the probate process, establishes that the executor has legal authority to act on behalf of the estate. Exchanges and other platforms typically require this documentation, along with proof of identity and often a certified death certificate, before allowing any transfer or sale.
Why probate authority matters for digital assets
Cryptocurrency held on a platform, rather than in a self-custodied wallet, functions similarly to a brokerage account when it comes to estate administration. The platform is a custodian holding assets on someone’s behalf, and it has no independent way to verify that the person requesting access is legitimately authorized unless a court has already made that determination. Letters testamentary serve as that verification, functioning much like the documentation used when an executor values other estate property for probate court filings.
What the process generally involves
- Opening probate. The will (or intestate succession rules if there is none) determines who is appointed, and the court issues formal letters granting authority.
- Locating and identifying the assets. This can be uniquely difficult with crypto, since there is no central registry — the executor typically needs account access information, hardware wallets, or private keys left by the deceased.
- Presenting documentation to the platform. Most exchanges have a dedicated estate or deceased-account process requiring letters testamentary, a death certificate, and identification.
- Following the platform’s specific transfer or liquidation procedure, which varies and can take considerably longer than a routine account transfer.
What makes cryptocurrency estates harder than typical accounts
Unlike a bank, which can usually locate an account once notified of a death, a self-custodied crypto wallet has no institution to contact at all. If the deceased held keys personally rather than on an exchange, and did not leave clear instructions on how to find or access them, those assets may become permanently unreachable — access is generally lost once the private key is unrecoverable, since there is no customer service line for a personal wallet. This makes advance planning, such as naming digital assets explicitly in a power of attorney or estate documents, especially important for anyone holding cryptocurrency directly.
Tax and valuation considerations
Selling estate cryptocurrency generally has tax implications for the estate or its beneficiaries, and rules around cost basis, valuation date, and reporting can be complex and vary by circumstance. Because cryptocurrency prices can swing significantly, the estate’s valuation date matters for tax purposes, and because rules in this area continue to evolve, an executor typically benefits from working with an estate attorney or tax professional familiar with digital assets rather than assuming general estate rules apply cleanly.
What to weigh
An executor’s authority to sell estate cryptocurrency ultimately rests on the same probate framework used for other property, but the practical hurdles are steeper: platforms require specific documentation, self-custodied assets may be unreachable without advance planning, and the irreversible nature of blockchain transactions leaves little room for error once a transfer is made. Anyone administering an estate with digital assets benefits from starting the documentation and discovery process early, given how much longer it can take compared to more conventional estate assets.
