Bitcoin Joint Tenancy Estate Planning: JTWROS Risks, Alternatives & Better Structures

What Joint Tenancy With Right of Survivorship Actually Means

Joint tenancy with right of survivorship (JTWROS) is a form of co-ownership where two or more people hold title to an asset simultaneously, and when one owner dies, the surviving co-owner(s) automatically inherit the deceased's interest — without probate, without a will, without court involvement. Title transfers by operation of law at the moment of death.

The legal definition requires the "four unities" to be present at the time the joint tenancy is created: unity of time (both owners acquired their interests at the same time), unity of title (both acquired through the same instrument), unity of interest (equal fractional ownership), and unity of possession (each has the right to possess the whole asset). If any unity is broken — one owner sells or transfers their interest — the joint tenancy severs and converts to tenancy in common.

This automatic survivorship feature is joint tenancy's primary planning appeal. If one of us dies, the other has immediate access and sole ownership. No waiting for probate. No executor. No court. For a traditional asset like a house or a bank account, this works exactly as intended. For Bitcoin, the story is considerably more complicated.

Joint tenancy is distinct from three other common co-ownership forms that Bitcoin holders need to understand: tenancy in common (no survivorship right; each owner's share passes through their estate), tenancy by the entirety (available only to married couples; adds creditor protection), and community property (available in nine states; provides a full double basis step-up at the first death). Each produces materially different tax and succession outcomes for Bitcoin.

How Joint Tenancy Works (and Fails) for Bitcoin

When most couples say they "jointly own" their Bitcoin, they mean one of three things — and only one of those three actually constitutes legal joint tenancy. Understanding the difference matters enormously at death.

Exchange Accounts: Closest to Real Joint Tenancy

Major exchanges including Coinbase, Gemini, and Kraken allow joint account structures where two individuals are both listed as account holders. Both have full access to the account. Both can trade, withdraw, or transfer Bitcoin. When one account holder dies, the survivor can typically notify the exchange with a death certificate and gain sole control over the account, often without probate court involvement — functionally similar to how a joint bank account works.

The caveats are important. Exchange joint account terms vary significantly. Not every exchange offers true JTWROS treatment — some treat joint accounts as tenants in common (requiring estate administration) or impose their own verification procedures that delay access for weeks regardless of the legal title arrangement. Before relying on an exchange joint account for estate planning, read the specific account agreement and confirm in writing how survivorship is handled. Do not assume it works the way a bank joint account does.

Exchange-held Bitcoin also carries exchange risk — the counterparty holds custody, not the account holder. For significant holdings, exchange custody concentrates multiple risks (exchange insolvency, regulatory action, account freezes) that self-custody eliminates.

Self-Custody: The "Joint" Fiction

Bitcoin does not have "joint ownership" in any technical sense. On the Bitcoin network, whoever holds the private key controls the Bitcoin. Period. There is no registry, no title office, no institution that recognizes two people as co-owners of a particular wallet. Ownership in Bitcoin is purely cryptographic: you sign transactions with the private key, and the network validates the signature. Everything else is a legal construct imposed on top of that cryptographic reality.

This means a "joint" hardware wallet is, technically, just a wallet where two people know the seed phrase. If both spouses have copies of the 24-word seed phrase, either can access the full wallet balance independently. If one person dies, the other already has the seed phrase and can access the Bitcoin immediately. This is the functional equivalent of JTWROS survivorship — but it is not legal joint tenancy. It is simply shared access to a private key.

The legal ownership question — who the Bitcoin "belongs to" for estate tax, income tax, divorce, and creditor purposes — is answered by the couple's intent, any written agreements, how contributions were made, and applicable state property law. Without documentation, the default assumption may be that the person who funded the purchases owns all of it. That creates §2040 inclusion risk (described below) and contribution-proof problems that surface precisely when you cannot easily produce documentation: after a death.

Hardware Wallets: Shared Seed Phrase = Shared Everything

A hardware wallet (Ledger, Trezor, Coldcard) generates a 12- or 24-word seed phrase that derives all private keys for that wallet. Whoever has the seed phrase can restore the wallet on any compatible device and access every Bitcoin in it. "Joint" hardware wallet ownership typically means both people have physical or documented copies of the seed phrase.

The security implication is stark: if one spouse takes the hardware wallet and seed phrase during a separation, the other spouse has zero ability to stop that transfer. The Bitcoin network does not recognize a property dispute. Bitcoin moved by a valid private key signature is Bitcoin moved. "Joint" hardware wallet ownership provides no legal mechanism to prevent unilateral taking — and in the event of divorce, death, or disagreement, whoever moves first moves the coins.

A more robust technical structure — 2-of-3 multisig — is described later in this guide. It actually enforces shared-control rules at the cryptographic level rather than relying on mutual good faith.

The Access Problem: Legal Title vs. Technical Control

Traditional joint tenancy works seamlessly for bank accounts and brokerage accounts because an institution stands between the asset and the owners. The bank sees the death certificate, verifies survivorship, and transfers the account. For Bitcoin in self-custody, there is no institution. JTWROS solves the legal title problem — the survivor is instantly the sole legal owner of all the Bitcoin. It does not solve the technical access problem.

If the deceased spouse was the sole custodian of the private keys, seed phrases, and hardware wallets, the surviving spouse may be the legal owner of Bitcoin they cannot access. The law gives them ownership; the cryptography does not give them access. The surviving joint tenant owns Bitcoin the way you might "own" a safe-deposit box key in a language you cannot read — the legal title is clear, the practical access is zero.

This creates three distinct failure scenarios:

Single custodian, no documentation (most common failure): One spouse manages all the Bitcoin, controls the hardware wallet, and stores the seed phrases without telling their partner where they are or how to use them. When that spouse dies unexpectedly, the survivor may spend months locating hardware devices in the deceased's belongings, trying to reconstruct seed phrases from partial notes, and potentially watching Bitcoin that should have been immediately available sit inaccessible for an indefinite period.

Shared access, no security discipline: Both spouses have the seed phrase, but neither takes physical security seriously — seed phrases stored in cloud notes, on phone screenshots, or written on paper kept in predictable locations. The joint access that makes survivorship work also creates multiple attack surfaces during the couple's lifetime.

Exchange "joint" account with restrictive terms: The couple relies on an exchange joint account assuming it provides immediate survivorship access, but the exchange's own procedures require estate documentation, legal review, or freeze the account upon notice of death. The Bitcoin is accessible in theory but practically unavailable for months.

Six Reasons Joint Tenancy Is Often the Wrong Structure for Bitcoin

Even setting aside the private key problem, JTWROS creates six distinct planning problems for Bitcoin-holding couples that do not exist with properly structured alternatives.

1. No Estate Tax Planning — Both Exemptions Underused

JTWROS automatically transfers all Bitcoin to the surviving joint tenant at the first death. This eliminates all planning flexibility for the survivor's estate. The survivor now owns 100% of the Bitcoin outright — no trust, no restriction, no structure. When the survivor later dies, their entire Bitcoin holding (which may have appreciated further) passes through their estate subject to full estate tax against only one exemption.

The contrast with a revocable trust using a credit shelter (bypass trust) structure is significant. With a properly structured revocable trust, the first death can fund a credit shelter trust with the deceased's estate tax exemption — holding Bitcoin outside the survivor's taxable estate at the second death. The surviving spouse uses the income from the credit shelter trust during their lifetime; the trust corpus passes to children at the second death with no additional estate tax. JTWROS gives away this planning opportunity permanently at the first death.

2. Creditor Exposure — One Spouse's Debts Can Reach the Bitcoin

In most states, a creditor of one joint tenant can reach that joint tenant's interest in jointly held property. For Bitcoin held in JTWROS, if one spouse faces a lawsuit judgment, business liability, or tax lien, the creditor may be able to attach or seize that spouse's share of the jointly held Bitcoin. In some states, a creditor can even force a partition sale, requiring the Bitcoin to be sold to satisfy the debt.

This is meaningfully different from tenancy by the entirety (available only to married couples in roughly 30 states), where neither spouse's individual creditors can reach TBE property — because the couple is treated as a single legal unit and neither spouse has a severable individual interest. For married Bitcoin holders with any creditor exposure — business owners, medical professionals, real estate investors — TBE provides protection that regular JTWROS does not.

3. Gift Tax Risk — Adding a Non-Spouse Joint Owner

If a Bitcoin holder adds a non-spouse as a joint tenant — an adult child, a sibling, a business partner — they are potentially making a taxable gift. Under §2511, a completed gift occurs when you transfer an interest to another person. Creating a JTWROS where the new joint tenant receives an equal fractional interest in Bitcoin worth more than the annual gift tax exclusion ($18,000 in 2025) triggers gift tax reporting requirements on Form 709.

For the spousal exception: transfers between spouses are generally gift-tax-free under the unlimited marital deduction (§2523), so adding a spouse to a JTWROS does not create a taxable gift. But parent-to-child joint tenancy for Bitcoin worth $200,000 creates a potential $100,000 gift (50% of value) that exceeds the annual exclusion and requires a Form 709 filing, drawing down the lifetime exemption. Most people do not realize this when informally "adding" a child to a Bitcoin account or wallet.

4. Medicaid Look-Back — Joint Assets Count

For Bitcoin-holding families where either spouse may eventually need long-term care, joint tenancy creates a Medicaid planning problem. Jointly held assets are generally countable for Medicaid eligibility purposes. When one spouse applies for Medicaid to cover nursing home costs, the jointly held Bitcoin counts as an available asset — potentially disqualifying the applicant or requiring spend-down before Medicaid coverage begins.

Transfers out of JTWROS within the five-year Medicaid look-back period are also scrutinized as potential disqualifying transfers. If a couple decides to restructure joint Bitcoin into a trust or transfer it to adult children within five years of a Medicaid application, those transfers may delay eligibility by months or years. Planning Bitcoin ownership structure with Medicaid look-back in mind — ideally well before either spouse's health creates urgency — is an important but frequently overlooked dimension of Bitcoin estate planning for couples over 55.

5. Divorce — Joint Tenancy Creates a Property Rights Dispute

Bitcoin held in JTWROS becomes a marital property dispute at divorce. Both spouses have legal title to the entire Bitcoin holding, and the divorce court must determine how to divide it equitably (in common-law states) or equally (in community property states, where it may already be characterized as community property anyway).

The practical problems are acute. Bitcoin is pseudonymous, easily moved, and difficult to trace once transferred to a new wallet. One spouse can effectively steal from the joint holding by transferring Bitcoin to a new wallet before the divorce proceeding begins — and if both have seed phrase access (as in informal joint custody), the other spouse has no cryptographic mechanism to stop it. Court orders directing someone to return Bitcoin that has already been moved to a new wallet are difficult to enforce when neither spouse controls the private keys to that new wallet.

Structuring Bitcoin in a way that clearly documents each spouse's separate or community interest — rather than relying on JTWROS — creates a cleaner record for any future dissolution proceeding.

6. Capital Gains — Only Half the Basis Gets Stepped Up

This is the most quantifiable cost of JTWROS versus community property or a properly structured trust. Under §1014, inherited property receives a stepped-up basis equal to fair market value on the date of death. For JTWROS, only the portion of the Bitcoin included in the deceased's estate — 50% under the §2040(b) spousal rule — receives the step-up. The surviving spouse's 50% retains the original purchase price as its basis.

For Bitcoin purchased at $20,000/BTC and now worth $100,000/BTC, the JTWROS survivor holds 50% of each coin at $100,000 basis (stepped up) and 50% at $20,000 basis (not stepped up). If the survivor eventually sells at $100,000/BTC, they recognize $80,000 of gain per coin on the non-stepped-up half — gain that community property treatment would have completely eliminated. Over a large Bitcoin position, the basis step-up difference between JTWROS and community property can represent hundreds of thousands to millions of dollars in avoidable capital gains tax.

§2040 — How Much of Your Bitcoin Is in the Taxable Estate

Section 2040 of the Internal Revenue Code governs how jointly held property is included in the gross estate of the first joint tenant to die. The general rule under §2040(a) is stark: the entire value of the jointly held property is included in the deceased joint tenant's estate — unless the executor can prove the surviving joint tenant contributed to the acquisition.

If one spouse purchased all the Bitcoin and the other contributed nothing, §2040(a) includes 100% of the Bitcoin in the purchasing spouse's estate at death. The marital deduction (§2056) shelters the transfer from immediate estate tax — but the Bitcoin now sits in the surviving spouse's estate, fully includable in their estate at their later death, with only one person's estate tax exemption having been used instead of two.

The Spousal JTWROS Exception: §2040(b)

Congress created a special rule for spouses. Under §2040(b), for JTWROS property held by a husband and wife (only — not parent/child, not domestic partners in all states), exactly 50% of the property's value is included in the estate of the first spouse to die, regardless of who contributed the purchase price. This is an automatic rule — no proof of contribution required, no election needed.

For non-spousal JTWROS — parent and child holding Bitcoin jointly, siblings, business partners — the general §2040(a) rule applies. The executor must trace contribution to prove anything less than 100% inclusion. Documentation of who purchased the Bitcoin, when, and with what funds becomes critical. Without clean financial records showing each party's contribution, the IRS will include 100% in the first decedent's estate.

The Basis Step-Up Problem: Only Half Gets Stepped Up

Section 1014 provides that inherited property takes a stepped-up (or stepped-down) basis equal to the fair market value on the date of death. For Bitcoin purchased at $10,000/BTC and now worth $70,000/BTC, the step-up eliminates $60,000 of embedded capital gain per coin that would otherwise be taxable when the survivor eventually sells.

Under JTWROS, only the portion of the Bitcoin included in the deceased's estate receives the basis step-up. For spousal JTWROS under §2040(b), that means 50% of the Bitcoin gets a full step-up and 50% retains the original cost basis. The survivor holds:

• 50% of the Bitcoin at the current market price basis (stepped up)
• 50% of the Bitcoin at the original purchase price basis (not stepped up)

For a Bitcoin position purchased at $10K/BTC now worth $70K/BTC, the blended basis per coin is $40K — not $70K. If the survivor sells Bitcoin after the step-up, they recognize $30K of gain per coin on the non-stepped-up half that would have been fully eliminated under a full step-up.

Joint Tenancy vs. Community Property

This is where the nine community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin) have a massive advantage. Under §1014(b)(6), community property receives a full step-up on both halves — the deceased spouse's half and the surviving spouse's half — because the entire community property interest is includable in the deceased's estate for step-up purposes, even though only the deceased's half is actually in the gross estate for estate tax purposes.

For a married couple in California, Texas, or Washington holding 10 BTC purchased at $10K/coin now worth $70K/coin, the community property double step-up at first death eliminates $600,000 of capital gain entirely — versus JTWROS, which leaves $300,000 of gain intact. This is one of the most compelling reasons to characterize Bitcoin as community property in community property states, and to document that characterization explicitly.

If you live in a community property state, holding Bitcoin as JTWROS instead of community property can cost you the double step-up by accident. Bitcoin acquired with marital funds during marriage in a community property state is presumptively community property — but that presumption can be rebutted by evidence of separate property treatment. If you held Bitcoin in individual name on an exchange and never documented it as community property, the executor may face a characterization dispute at death. A community property agreement or transmutation agreement documenting Bitcoin's character as community property eliminates this uncertainty.

Joint Tenancy vs. Tenancy in Common

Tenancy in common (TIC) is the other primary form of co-ownership, and it differs from JTWROS in one critical way: there is no right of survivorship. When a tenant in common dies, their fractional interest passes through their estate under their will or intestacy law — not automatically to the surviving co-owners.

For Bitcoin held as TIC, this means the deceased co-owner's share goes through probate (unless held in a trust) and is distributed according to the will or intestacy law of the deceased's state. The surviving co-owner retains only their original fractional interest and receives nothing additional from the deceased's share automatically.

TIC is appropriate when the co-owners want to preserve their separate succession rights — for example, two business partners who each want their Bitcoin share to pass to their own families, not to the surviving partner. TIC is also the default form of co-ownership when a JTWROS is severed (one party transfers their interest), when the four unities are not met at creation, or when property is inherited by multiple heirs who did not create a JTWROS.

For Bitcoin, TIC creates the most probate-heavy outcome unless each co-owner's share is held in a trust. Each deceased co-owner's share must go through probate proceedings in their state of domicile, which for Bitcoin can create technical access problems during the probate period — the estate's executor may need to access private keys, and the probate court may require the Bitcoin to be held in a court-supervised account during administration.

For married couples, TIC is rarely the correct choice — either JTWROS (for automatic survivorship) or a joint revocable trust (for automatic survivorship plus tax and succession planning) is typically superior. For unmarried co-owners, TIC with each party's share held in a revocable trust gives each person automatic succession control over their share without probate, without creating a survivorship right they may not want.

Tenancy by the Entirety: The Overlooked Protection for Married Bitcoin Holders

Tenancy by the entirety (TBE) is a form of co-ownership available exclusively to married couples, recognized in approximately 30 states including Florida, Maryland, New York, Pennsylvania, Hawaii, and others. It is one of the most powerful — and least discussed — estate planning tools for Bitcoin-holding married couples.

TBE treats the married couple as a single legal unit for ownership purposes. Neither spouse can unilaterally transfer, encumber, pledge, or convey their interest without the other's consent. The most important planning benefit: a creditor of one spouse generally cannot reach TBE property to satisfy that spouse's individual debts. Only a creditor of both spouses together — a joint debt — can reach TBE property.

For Bitcoin-holding married couples with creditor exposure — small business owners, medical professionals, real estate investors, executives with personal guarantees on business debt — TBE provides a layer of asset protection that regular JTWROS does not. Bitcoin held as TBE cannot be seized by a judgment creditor of one spouse; Bitcoin held as regular JTWROS can be.

TBE does have limits. It is only available in states that recognize it (check your state before relying on this structure). It dissolves automatically upon divorce, converting to tenancy in common. For exchange-held Bitcoin, major exchanges may not accommodate TBE account titling in the same way a real estate title company does — confirm with your exchange. For self-custodied Bitcoin, TBE creates a useful legal framework for ownership documentation even though it has no cryptographic enforcement mechanism.

For Bitcoin-specific TBE planning — including which states recognize it for personal property like Bitcoin, how to document TBE ownership for self-custody, and how TBE interacts with estate tax — see our detailed guide to Bitcoin Tenancy by the Entirety.

The estate tax treatment of TBE for married couples is the same as JTWROS: §2040(b) applies automatically, including 50% in the first estate. The creditor protection is TBE's unique advantage over JTWROS; the estate and income tax consequences are identical.

Better Structures for Bitcoin-Holding Couples

For most Bitcoin-holding couples, one of four structures will outperform JTWROS on every relevant dimension: probate avoidance, access planning, basis optimization, estate tax efficiency, and flexibility after the first death.

Revocable Living Trust With Pour-Over Will

A revocable living trust is the workhorse of Bitcoin estate planning for couples. The grantor (or both spouses as co-grantors) creates a trust, transfers Bitcoin into the trust, and designates a successor trustee who takes over management upon death or incapacity. The pour-over will acts as a safety net — any Bitcoin not already in the trust at death "pours over" into the trust through the will, though this pour-over transfer does go through probate (which is why direct trust funding during lifetime is preferable).

The revocable trust achieves the same probate avoidance as JTWROS while also: providing incapacity management via successor trustee; enabling a credit shelter trust at the first death to use both spouses' exemptions; specifying exactly what happens to Bitcoin after the surviving spouse's death (preventing the survivor from inadvertently disinheriting children from a prior relationship); and accommodating a Letter of Instructions to the successor trustee detailing private key locations, hardware wallet access, and multi-sig procedures.

Community Property Trust (CP States)

Couples in community property states can hold Bitcoin in a community property trust — a revocable living trust that explicitly characterizes the Bitcoin as community property. This preserves the §1014(b)(6) double basis step-up at first death while providing all the other benefits of a revocable trust structure. Some states (Alaska, Tennessee, South Dakota) allow non-resident couples to opt into community property trust treatment for certain assets, potentially accessing the double step-up even from common-law states.

For California, Texas, and Washington Bitcoin holders specifically, the community property trust is often the optimal structure: probate avoidance, double step-up, credit shelter planning, and access management — all in one document.

SLAT — Spousal Lifetime Access Trust

A Spousal Lifetime Access Trust (SLAT) is an irrevocable trust into which one spouse (the "donor spouse") transfers Bitcoin, removing it from their taxable estate. The other spouse (the "beneficiary spouse") has access to the trust's income and principal during their lifetime, providing the couple ongoing access to the Bitcoin even after the transfer. When the beneficiary spouse dies, the remaining Bitcoin passes to children or other beneficiaries without additional estate tax — having been removed from the donor's estate at the time of transfer.

A SLAT is particularly powerful for Bitcoin because it: removes Bitcoin from the estate at today's value (before further appreciation); uses the donor spouse's gift/estate tax exemption at transfer; allows the beneficiary spouse to continue accessing Bitcoin during their lifetime; and passes the remaining Bitcoin to the next generation free of estate tax at the beneficiary spouse's death. The primary risk is the "reciprocal trust doctrine" — if both spouses create SLATs for each other with substantially identical terms, the IRS may collapse them and include the Bitcoin back in both estates. Structure each SLAT with distinct terms, different trustees, and staggered funding dates to avoid this risk.

Separate Trusts With Reciprocal Provisions

For couples with complex family situations — prior children, significant separate property, business interests — separate revocable trusts for each spouse (rather than a joint trust) often provide the clearest structure. Each spouse's trust holds their separately owned Bitcoin; jointly owned Bitcoin is held in a joint trust or divided and contributed to each separate trust. Reciprocal provisions coordinate the distribution plan across both trusts, ensuring the surviving spouse is provided for while preserving each spouse's ability to direct their Bitcoin to their own beneficiaries after the surviving spouse's death.

The Self-Custody Solution: 2-of-3 Multisig

For couples committed to self-custody — holding their own keys rather than relying on an exchange — joint tenancy creates a real-world access dilemma: either both spouses have the seed phrase (creating security risk and unilateral-taking risk) or only one spouse has it (creating access failure at death). Neither outcome is satisfactory.

The solution that addresses both concerns simultaneously is a 2-of-3 multisig wallet. In a 2-of-3 multisig setup, three independent private keys are generated. Spending Bitcoin from the wallet requires any two of the three keys to sign the transaction. No single key provides unilateral access.

For a Bitcoin-holding couple, the structure works as follows:

• Key 1: Spouse A holds a hardware wallet (e.g., Coldcard) with their signing key
• Key 2: Spouse B holds a hardware wallet with their signing key
• Key 3: A trusted third party — an attorney, an institutional Bitcoin custody service, or a trusted family member — holds the third key (or its backup)

During normal operation, either spouse can transact using their own hardware wallet plus the third-party key. No cooperation between spouses is required for day-to-day transactions. No single key holder has unilateral access to the Bitcoin. If one spouse acts adversarially (during divorce or disagreement), they cannot move the Bitcoin without the third party's cooperation.

At the death of either spouse, the surviving spouse accesses the Bitcoin using their own key plus the third-party key — no cooperation from the deceased's estate or executor required. The survivor does not need to locate the deceased's hardware wallet, recover the deceased's seed phrase, or wait for probate. The 2-of-3 structure provides true Bitcoin-native joint succession without requiring either spouse to hold the other's key.

Services such as Unchained Capital, Casa, and Liana provide institutional co-signer arrangements for this type of multisig setup, acting as the third key while the couple holds two of the three keys. For couples who want professional key management without relying on a family member or attorney, these services provide a vetted, Bitcoin-native solution that directly addresses the self-custody joint succession problem.

When Joint Tenancy Does Make Sense for Bitcoin

JTWROS is not always wrong. There are specific situations where it is a reasonable, practical choice:

• Small Bitcoin holdings (under $50K) where the tax and planning consequences are immaterial; simplicity beats the overhead of a trust
• Both parties are technically competent Bitcoin users who each independently manage access and security — no single point of failure
• No children from prior relationships and no desire to restrict what the survivor does with the Bitcoin after the first death
• Community property states where the double basis step-up is achieved by correctly characterizing Bitcoin as community property — JTWROS in addition to community property characterization can be redundant or counterproductive
• Exchange accounts where the primary goal is immediate access for the survivor and the exchange's joint account agreement actually provides JTWROS treatment with clear survivorship procedures
• Temporary holding structure while a revocable trust is being drafted and funded — JTWROS as a bridge, not a permanent plan

The key test is whether the tax cost of the limited basis step-up, the loss of credit shelter flexibility, and the access planning gap are material for your specific holding and family situation. For holdings under $50K with technically competent co-owners and no blended family complexity, JTWROS may be adequate. For anything more significant, the structures described above will outperform it.

The Revocable Trust: Full Comparison

A revocable living trust addresses every problem that JTWROS creates — and adds planning flexibility JTWROS can never provide:

How to Transfer Bitcoin Into a Revocable Trust

For exchange-held Bitcoin: update the account title to the trust (e.g., "John Smith and Jane Smith, Trustees of the Smith Family Trust dated January 1, 2025"). Most major exchanges accommodate trust accounts with a trust certification document. The successor trustee — named in the trust document — takes over the account immediately upon the grantor's death or incapacity without court involvement.

For self-custodied Bitcoin: the trust document specifies the trust as the owner of the wallet. A separate Letter of Instructions (kept with or referenced in the trust document, stored securely) documents the wallet locations, hardware device locations, seed phrase locations, and multi-sig arrangements. The successor trustee accesses the Bitcoin using the information in the Letter of Instructions — a process that can be completed within hours of death, far faster than any probate or exchange account claim process.

See our comprehensive guide to Bitcoin estate planning for a full walkthrough of trust funding, Letter of Instructions best practices, and successor trustee selection for Bitcoin-specific situations.

Non-Spousal Joint Tenancy: The Contribution Tracing Trap

For Bitcoin held in JTWROS by non-spouses — parent and adult child, two business partners, two friends — the §2040(a) contribution tracing rule creates specific documentation obligations that most people never fulfill.

Under §2040(a), the IRS presumes that 100% of the Bitcoin belongs in the first joint tenant's estate unless the executor proves (by "adequate consideration furnished by the other joint tenant") that the surviving joint tenant contributed to the purchase. If two business partners each contributed 50% of the purchase price for a joint Bitcoin position, the surviving partner needs documentation to prove their contribution — wire transfer records, bank statements, exchange trade confirmations — or the IRS will include 100% in the deceased partner's estate.

For Bitcoin purchased in cash, peer-to-peer, or without clean financial records, this proof may be impossible to produce after the fact. The solution: maintain contemporaneous documentation of each joint owner's contribution at the time of purchase, and consider tenancy in common instead of JTWROS for non-spousal co-ownership, with each party's share held in their own revocable trust.
