Crypto Inheritance After Death: First Steps Without a Seed Phrase
In crypto inheritance, paper title and key access are different: a will does not open a self-custody wallet by itself. Recovery may be possible if a seed phrase, a device, a vault, or an exchange account remains; without artifacts, blind "cracking" is not realistic. Start with an assessment through wallet recovery—without sending a complete seed phrase in a chat.
A will does not supply the seed phrase
A notary or court can document a transfer of property. They cannot reconstruct a BIP39 phrase or "reassign" an address on the blockchain the way a bank reassigns an account. A self-custody wallet (MetaMask, Ledger, a paper backup) opens with knowledge of the seed or key, or with a decryptable file on a device—not with a certificate of inheritance.
An exchange account is a different branch: the platform holds the assets and may run its own estate process with its own documents and timelines. That is not a guarantee and not a single rulebook; each exchange decides. Do not confuse this with a living owner who forgot a password—use the checklist in forgot crypto wallet password. If only part of the phrase survives, see the limits in partial-seed recovery.
Separately, heirs often do not know crypto existed at all. It is reasonable to look quietly for devices, paper notes, password managers, and exchange emails—without posting finds in family chats that include unknown "helpers."
When recovery is realistic—and when it is not
| What you still have | Realistic access |
|---|---|
| Complete seed / hardware wallet plus seed | High—import on a clean device |
| Exchange account and estate documents | A platform process may be possible |
| Vault, keystore, or phone with the app | Assessment, not a promise |
| Partial seed with known positions | Follow the separate scenario |
| No seed, file, or exchange account | Blind access is generally unrealistic |
A realistic path is an exchange plus the package it actually requests, or local artifacts (vault, wallet.dat, an old device), similar to recovering access after losing a phone. An unrealistic pitch is "we will open any deceased person's wallet" with no phrase and no file. Cryptography does not make an exception for an heir.
If the address held protocol positions, a simple app balance may be incomplete. Do not sign "just in case" transactions from someone else's seed in a browser: a bad exit is not cured by a will. Describe what data exists first, without pasting the complete phrase into a form.
First steps for an heir: checklist
- Record what is known: exchange versus self-custody, networks, addresses, devices—without publishing a complete seed phrase.
- Search for an offline phrase backup, a hardware wallet, paper, or a safe; do not photograph the seed into cloud storage.
- For an exchange account, prepare the documents the platform itself requests; do not hand access to a crypto "intermediary."
- For a self-custody wallet, look for a vault, a phone backup, or an old PC; do not install "inheritance helpers" on those devices.
- If words are missing, do not guess them on random "BIP39 checker" sites.
- Describe the artifacts available for an assessment through wallet recovery.
- Do not send a complete seed phrase to an "inheritance crypto lawyer" chat without an agreement and a safe handling process.
- Do not buy "guaranteed unlocking of a deceased person's wallet."
- Do not restore the phrase in a browser that has third-party extensions.
The goal of the first days is an inventory of data and a stop on key leakage, not a race "before the estate file closes." Paper title without keys does not move coins.
What not to do: "inheritance services" and the seed phrase
After an owner's death, search results fill with "inheritance recovery" offers: send the missing words, upload a photo of the seed, or grant remote access to the deceased person's computer. That is the same risk class as recovery phishing. Anyone who receives the complete phrase can withdraw assets regardless of the will.
The outcome depends on artifacts, not on advertising urgency. An honest assessment is whether access is attainable, which files must not be guessed against, and whether a separate legal track is needed for an exchange account. The model without a miracle promise is on the about page. Do not mix an access task with "stolen funds recovery": there is no scammer TxID here unless someone already withdrew after the death.
Risks and limitations
- Without a seed phrase, device, vault, or exchange account, practical access is almost certainly closed—paper title does not create it.
- A complete seed phrase sent to an "inheritance service" lets someone withdraw assets regardless of the will.
- Blind password or BIP39 guessing on random sites can damage a file or expose the rest of the phrase.
- The outcome is not guaranteed even with artifacts: it depends on data completeness and each exchange's process.
- Signing DeFi transactions from someone else's seed in an infected browser can destroy what might still have been saved.
