A digital executor handles your Bitcoin estate after death. Here's how to designate the right person, what to document in a Letter of Instruction, and the professional services that make Bitcoin inheritance work.
Your will names an executor to handle your estate. But for Bitcoin, you also need someone with specific technical knowledge — someone who can locate your holdings, access your hardware wallets, and transfer Bitcoin to your beneficiaries. This person is often called a digital executor or digital asset executor.
Without a digital executor who knows what to do, your Bitcoin could be permanently inaccessible even if your legal estate is fully settled.
A digital executor is a person you designate to manage your digital assets after death. For Bitcoin holders, this means:
In most US states, the digital executor's role is handled by your general estate executor (named in your will). However, since most executors have no Bitcoin technical knowledge, it's worth specifically designating a technically capable person — either as co-executor or by providing detailed documented instructions.
A traditional estate executor is typically a spouse, adult child, or attorney. Their duties involve probating the will, paying debts, filing tax returns, and distributing assets.
They know how to:
They likely do NOT know how to:
If your executor can't complete these steps, your Bitcoin is effectively locked forever — even if you legally bequeathed it to your children.
A capable Bitcoin digital executor needs knowledge of, or instructions covering:
1. Where your Bitcoin is
2. How to access each holding
3. What to do with each holding
4. Tax implications
The most important document you can create is a Letter of Instruction (sometimes called a crypto estate letter or digital asset inventory). This is NOT a legal document — it does not replace your will. It is a practical guide.
What to include:
Section 1: Asset Inventory List all Bitcoin holdings with amounts, locations, and account identifiers:
Coinbase account: [email address]
- Approx. 0.5 BTC as of [date]
- Account can be claimed via identity verification + death certificate
- Contact: support.coinbase.com → "Deceased Account"
Ledger Nano X hardware wallet:
- Stored in: [physical location]
- Contains: 2.0 BTC
- PIN: [stored separately at [location]]
- Seed phrase: [stored at [SEPARATE location]]
Unchained Capital (multi-sig):
- I hold 2 of 3 keys; Unchained holds 1
- Contact Unchained at: [contact info]
- They will guide you through the inheritance process
- My two keys are at [location 1] and [location 2]
Section 2: Access Procedures Step-by-step instructions for accessing each holding. Be specific — assume zero Bitcoin knowledge.
Section 3: Beneficiary Instructions How you want the Bitcoin distributed: sell and send USD, transfer BTC to specific wallets, hold for children until a specific age, etc.
Section 4: Professional Contacts Your Bitcoin-knowledgeable CPA, estate attorney, any professional custodians, and a technical advisor who can assist the executor if needed.
What NOT to do:
What TO do:
The seed phrase is NOT in the Letter of Instruction itself — it's in a separate, secure location referenced in the letter. The letter says "seed phrase is in the safe at [location]" but does not contain the actual seed phrase.
Several companies provide structured Bitcoin inheritance services:
Casa (casa.io): Casa's Gold and Diamond plans include a structured inheritance process. Your executor contacts Casa, verifies identity, and Casa guides them through recovering the multi-sig wallet. Casa's design specifically addresses the executor problem — they're your professional third key holder.
Unchained Capital: Unchained's multi-sig custody includes an inheritance process. They have experience working with executors and estates. Your executor contacts Unchained, provides death certificate and legal authority, and Unchained assists with key recovery.
Vault12: A digital vault service that lets you distribute encrypted shares of your seed phrase to trusted guardians. At death, your designated heir requests the shares from guardians to reconstruct access.
CipherWill: Creates encrypted Bitcoin inheritance packages with time-locked delivery mechanisms.
Authority to act: Your estate executor needs legal authority to access accounts. For regulated custodians (exchanges, IRAs), they typically need:
For self-custodied Bitcoin (hardware wallets), there's no legal gating — whoever has the physical hardware and seed phrase can access the funds. This is why documentation is more important than legal authority for self-custody.
State digital asset laws: Many states have adopted the Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA), which gives fiduciaries (including estate executors) the legal right to access digital assets. However, technical access is a different question — legal authority doesn't help if your executor doesn't know the seed phrase.
Probate timing: Probate can take months to years. Bitcoin markets don't wait. Consider whether your executor should be empowered to make immediate decisions about Bitcoin holdings, or whether a professional custodian should maintain control during the probate process.
Not everyone has a technically sophisticated family member. Consider designating a trusted friend who is Bitcoin-knowledgeable as:
This person doesn't need to be your closest family member — they need to be technically capable, trustworthy, and willing to serve.
What is a digital executor for Bitcoin? A digital executor (or digital asset executor) is the person responsible for locating, accessing, and transferring your Bitcoin after your death. They may be your general estate executor or a separately designated technically capable person. Without someone who can actually access your holdings, your Bitcoin is effectively lost regardless of who legally inherits it.
What happens to Bitcoin on an exchange when someone dies? Exchange accounts are frozen at death. Your executor must contact the exchange, provide a death certificate and letters testamentary, verify identity, and request account transfer or liquidation. Each exchange has its own deceased account process — typically accessible through their support portal. This process can take weeks to months.
What happens to Bitcoin in a hardware wallet when someone dies? Nothing happens automatically — the Bitcoin is unchanged on the blockchain. Your executor needs the hardware wallet device plus the seed phrase to access it. Without both (or just the seed phrase to restore on a new device), the Bitcoin is permanently inaccessible.
Should I put my Bitcoin seed phrase in my will? No. Wills become public documents after death (probate is a public process). A seed phrase in your will means anyone can read it and steal your Bitcoin. Keep seed phrases in secure, private documents — not in your will. Your will can reference that Bitcoin holdings exist and direct the executor to the Letter of Instruction.
Can I use a digital vault service instead of a Letter of Instruction? Yes — services like Vault12 and CipherWill provide structured digital inheritance that can supplement or replace a traditional Letter of Instruction. These services typically use cryptographic techniques to ensure your heirs receive access without exposing your seed phrase prematurely. They are not substitutes for proper legal estate planning, but they are valuable technical complements.
How do I update my Bitcoin estate plan as my holdings change? Review and update your Letter of Instruction at least annually or whenever:
