Jointly owned crypto after a death

Crypto can be shared between two people in several ways, and after one of them passes away the situation is rarely as simple as “the other person keeps it.” This page explains the forms joint ownership can take, what the law does and does not change, and the correct order of work. It is mechanical and jurisdiction-neutral: local law decides the details, and this page never tells you what to do in your specific situation.

What “joint” can mean in crypto

• An exchange account whose balance is claimed to be wholly or partly joint property. That does not automatically mean the account itself is in two names; check the current account registration and the terms of the platform concerned. After a death, the platform’s official procedure applies, the account does not automatically belong to the survivor. See exchange accounts after a death.
• A shared self-custody wallet. Two people have the same recovery or key material. Whether each can access the funds on their own depends on the wallet configuration; a passphrase, additional key or other authorisation may be needed. That says nothing about who legally owns what.
• A multisig wallet. Two or more people each hold a key (2-of-2, 2-of-3). If one signer passes away, the remaining signers may need the estate’s cooperation, and ownership shares can matter. See bitcoin multisig inheritance and smart-contract wallets.
• Informal access. One person gave the other a password or device “just in case.” Access was shared; ownership was not.

What the law does and does not change

The core principle is the same as everywhere on this website: access is not title. Words, keys or a device can be technical access material, but do not give standalone access in every configuration; additional data, keys or authorisations may be needed. Legal ownership is decided by the applicable law and by relevant evidence, such as account registration, funding records, agreements and statements. See legal authority vs technical access.

Do not infer legal ownership solely from who managed the account, who held a wallet or who funded the purchase. For joint or disputed holdings, it must be established which rights the parties had under the relevant agreements and the applicable law; have this assessed locally if in doubt. A shared wallet is not automatically a joint account, and a joint account is not automatically a shared wallet.

What the estate process changes

• To the extent that the right or share of the person who passed away forms part of the estate under the applicable law, it must be inventoried and administered as such; it then belongs in the estate inventory and valuation, even if the survivor holds full technical access.
• The survivor does not automatically own the whole wallet because they can use it.
• Division follows the will, the law, or an agreement with legal standing, not whoever moved the funds first. See dividing crypto between heirs.
• Where there is no will, the normal intestacy rules apply to the share of the person who passed away: who inherits crypto without a will.

The order of work

1. Preserve the deceased person’s relevant materials and carefully document what appears to be used jointly. Do not automatically treat the survivor’s devices, accounts or records as estate material. If data from them seems needed to establish joint ownership, first determine which access, consent or procedure is appropriate.
2. Establish who owned what. Evidence: account registration, statements, funding records (who paid for the crypto), written agreements, and documents of the person who passed away. Account registration, funding records, agreements, statements and other circumstances can help establish what rights the parties had; the legal outcome follows from the applicable law and the facts.
3. Establish authority over the share of the person who passed away through the estate process. See legal authority vs technical access.
4. Classify where it was held (exchange or self-custody) because the routes differ. See exchange or self-custody.
5. Only then act. Moving, selling or dividing the share of the person who passed away before authority is confirmed is where shared-wallet estates go wrong.
6. Document everything you did, in order, for the estate record.

What this page is not

It is not legal advice and it cannot tell you how joint ownership works in your country. It states the mechanical facts and the questions to resolve with local professionals, see who can help with inherited crypto.

Rules and deadlines can change, and this page may not yet reflect the latest position, have the current rules confirmed by a local lawyer, notary or tax adviser before acting. Spotted something that no longer matches? Contact us and we will correct it.
