Unmarried partners have no automatic Bitcoin inheritance rights in most states. This guide covers wills, beneficiary designations, trust structures, and access planning to protect your partner's claim to your Bitcoin.
Married couples have automatic inheritance rights in most jurisdictions. Unmarried partners — regardless of how long you have been together — typically have none. If your partner holds Bitcoin and dies without a will naming you as a beneficiary, you may have no legal claim to that Bitcoin.
This is a critical gap in Bitcoin estate planning that most couples in long-term relationships fail to address. This guide covers the specific steps unmarried partners need to take to protect shared Bitcoin assets.
When someone dies without a will (intestate), most states distribute assets according to intestacy laws. These laws prioritize:
Unmarried partners — regardless of relationship duration — are typically absent from these lists. A partner of 20 years has no automatic inheritance rights in most US states without legal documentation.
Bitcoin makes this worse. Unlike a bank account, where a court might order the bank to provide access during an estate dispute, Bitcoin with no designated successor is simply inaccessible if private keys are not transferred.
Some states recognize domestic partnerships or common law marriages that provide inheritance rights:
Common law marriage (recognized in: Texas, Colorado, Iowa, Kansas, Montana, New Hampshire, Oklahoma, Rhode Island, South Carolina, Utah, and Washington DC) requires demonstrating a genuine marriage-like relationship with cohabitation and mutual holding out as spouses. These relationships can provide inheritance rights, but they must be affirmatively proven.
Domestic partnerships vary enormously by state. Some provide full marital rights; others provide limited benefits. Do not assume your state's domestic partnership provides inheritance rights — verify specifically.
Even in states that recognize these relationships, the documentation requirements and legal challenges can be significant. A proper will is always clearer.
The most important step: create a legally valid will naming your partner as a beneficiary.
A simple will that names your partner as beneficiary for Bitcoin assets, with specific instructions for access, resolves the primary legal problem. Without a will, courts follow intestacy rules that exclude you.
What the will should include:
Will services: Legalzoom, Trust & Will, and Willing offer online will creation starting around $100. For Bitcoin holdings above $100,000, consult an estate attorney who understands digital assets.
For Bitcoin held on exchanges, beneficiary designations are separate from your will. Many exchanges now offer transfer-on-death (TOD) or payable-on-death (POD) designations.
Coinbase: Supports account transfer procedures. Check their current process for adding a beneficiary.
Gemini: Has specific estate planning documentation processes.
Kraken: Requires estate procedures through their support process.
Contact your specific exchange to understand their beneficiary designation options. These designations transfer assets directly to your named beneficiary without going through probate — faster and simpler than a will for exchange-held Bitcoin.
A will names your partner as a beneficiary. But how do they actually access the Bitcoin? This requires separate access documentation.
Your access documentation should include:
Critical rule: Do not put seed phrases in your will. Wills become public record after probate. A seed phrase in a public document is an invitation to theft.
Instead, store the seed phrase backup separately in a fireproof safe, safety deposit box, or professional vault service. Reference the location in your will — something like: "Access instructions for Bitcoin are in the fireproof safe in the home office."
Inheritance planning services: Casa Inheritance, Unchained, Vault12, and CipherWill offer specialized Bitcoin inheritance services that manage the access documentation problem professionally.
For larger Bitcoin holdings or complex situations, a revocable living trust is more powerful than a will alone:
Avoids probate: Assets in a trust transfer to your partner without going through the court process, which can take months to years.
Privacy: Unlike wills, trusts are not public record. The contents of your Bitcoin holdings remain private.
Flexibility: You can specify exactly how and when Bitcoin is distributed — for example, releasing access over time rather than all at once.
Management during incapacity: If you become incapacitated (not just death), the trust successor trustee can manage the Bitcoin without a court order.
A trust requires an estate attorney to set up properly. Typical cost: $1,500-$5,000 for a basic revocable living trust, more for complex situations.
For living partners who want to share Bitcoin ownership while both alive:
Multisig with shared keys: A 2-of-3 multisig where both partners hold one key and a third key is stored in backup can give both partners access to funds while requiring agreement to move large amounts. Services like Unchained and Casa facilitate shared custody setups.
Exchange joint accounts: Few Bitcoin exchanges support formal joint accounts. Sharing login credentials is risky and potentially violates terms of service.
Caution with shared seed phrases: Sharing a single seed phrase means both partners have unilateral access to all funds. This works on trust but provides no protection if the relationship ends.
Can my partner inherit my Bitcoin without a will? In most US states, no. Unmarried partners have no automatic inheritance rights. Without a will, Bitcoin typically passes to your closest blood relatives according to intestacy laws.
What happens to Bitcoin on an exchange if I die without instructions? Exchanges freeze the account and require estate documentation. Your partner would need to go through probate with a valid legal claim to your estate. Without a will naming them as a beneficiary, they may have no legal basis to claim the funds.
Is a beneficiary designation better than a will for Bitcoin? Beneficiary designations (where available) are faster and avoid probate. They work in addition to a will, not instead of one. For self-custody Bitcoin, beneficiary designations are not applicable — you need a will or trust plus access documentation.
Can I give my partner access to my hardware wallet? Yes — sharing the seed phrase or keeping a hardware wallet accessible to your partner is the simplest solution for practical access. But this is a separate question from legal ownership. Even with access, legal disputes from other heirs can complicate ownership if you do not have proper documentation.
