You and your spouse hold Bitcoin. Maybe it started as a speculative position and grew into the largest asset on your balance sheet. Maybe you have been accumulating methodically for years. Either way, the question is no longer whether to do estate planning — it is which trust structure protects your family and minimizes the tax bill when one of you dies.

The answer depends on your state, the size of your estate, whether this is a first marriage or a blended family, and — critically for Bitcoin holders — who controls the private keys and how succession works for an asset that cannot be recovered if access is lost.

This guide walks through every structural option available to married couples holding Bitcoin: joint revocable trusts, separate revocable trusts, A/B bypass trusts, QTIP trusts, and the interplay with community property law. By the end, you will know which structure fits your situation and exactly how to implement it.

Joint vs. Separate Revocable Trusts for Bitcoin Holders

The first structural decision married couples face is whether to create one joint revocable trust that both spouses share or two separate revocable trusts — one for each spouse. Neither answer is universally correct. The right choice depends on your state's property law, whether your Bitcoin was acquired before or during the marriage, and how you manage custody and key access.

Joint Revocable Trust

A joint revocable trust is a single trust document where both spouses serve as co-trustees and co-grantors. All community or jointly held assets go into one trust. Both spouses have full control during their lifetimes, and the trust typically includes provisions for what happens when the first spouse dies — often splitting into sub-trusts (the A/B structure discussed below).

Advantages for Bitcoin holders:

  • Simpler administration — one trust, one set of records, one custodian relationship
  • Natural fit for community property states where Bitcoin acquired during marriage is already jointly owned
  • Both spouses can manage the trust assets, which matters when one spouse is more technically proficient with Bitcoin custody
  • Lower legal fees — one document instead of two

Disadvantages:

  • Commingling separate property (Bitcoin one spouse owned before marriage) with community property can destroy the separate property characterization — and the tax advantages that come with it
  • At first death, administration becomes more complex because the trust must split into sub-trusts, and Bitcoin held in a single wallet must be allocated between them
  • In a divorce, untangling a joint trust adds legal complexity and cost

Separate Revocable Trusts

Each spouse creates their own revocable trust. Spouse A's Bitcoin goes into Trust A. Spouse B's Bitcoin goes into Trust B. Each spouse is the sole trustee and sole grantor of their own trust.

Advantages for Bitcoin holders:

  • Clean separation of assets — critical when one spouse brought significant Bitcoin into the marriage
  • At first death, only the deceased spouse's trust becomes irrevocable. The surviving spouse's trust is completely unaffected.
  • Each trust can name different beneficiaries — important in blended families
  • Cleaner key management: each spouse controls their own hardware wallet and seed phrase for their own trust's Bitcoin

Disadvantages:

  • Higher setup and maintenance cost — two documents, two sets of amendments
  • Community property must be divided between the trusts, which requires a property allocation agreement
  • May lose the full community property step-up at first death if not structured carefully (more on this below)

Bitcoin-Specific Consideration: Key Control Defines Ownership

With traditional assets, trust titling is administrative. You call the brokerage and change the account title. With self-custodied Bitcoin, the person who holds the seed phrase controls the asset — regardless of what any legal document says. This means trust structure must align with key management.

If you create a joint revocable trust but only one spouse has the seed phrase, you have a functional mismatch between legal ownership and practical control. If you create separate trusts but both spouses' Bitcoin sits in the same hardware wallet, you have a titling problem that could create disputes at death or divorce.

The rule is straightforward: the trust structure should mirror the key management structure, and both should be documented in your estate plan.

Joint vs. Separate Revocable Trust Comparison
Factor Joint Revocable Trust Separate Revocable Trusts
Number of documents One Two
Best for Community property states, first marriages, simpler estates Separate property, blended families, high-asset couples
Administration at first death Trust splits into sub-trusts (more complex) Only deceased spouse's trust changes (cleaner)
Bitcoin key management Shared wallet or multi-sig with both spouses Separate wallets per spouse/trust
Divorce implications Must unwind joint trust Each spouse keeps their own trust
Community property step-up Preserved naturally Requires careful allocation agreement
Typical legal cost $3,000–$7,000 $5,000–$12,000

How to Title Bitcoin in a Joint Revocable Trust

Creating the trust document is the easy part. The harder part — and the step most families skip or do incorrectly — is actually transferring Bitcoin into the trust. A trust that owns nothing protects nothing.

Titling Bitcoin in a joint revocable trust works differently depending on how the Bitcoin is held.

Exchange and Custodian Accounts

Most major custodians (Coinbase, Fidelity Digital Assets, Gemini, Swan Bitcoin) allow trust accounts. The process typically involves:

  1. Opening a new account titled in the trust's name — for example, "The Smith Family Trust dated January 15, 2026, John Smith and Jane Smith, Trustees"
  2. Submitting the trust's certificate of trust (a summary document that confirms the trust exists, names the trustees, and describes their powers — without disclosing the beneficiaries or distribution terms)
  3. Transferring Bitcoin from your individual account to the trust account
  4. Closing or zeroing out the individual account

This transfer from your individual account to your revocable trust is not a taxable event. You are the same taxpayer before and after. Your cost basis carries over. There is no Form 1099 generated.

Self-Custody: Hardware Wallets and Private Keys

Self-custodied Bitcoin presents a unique challenge because there is no third-party custodian to update a title with. The Bitcoin does not know who owns it. Ownership is determined by key control and legal documentation.

To properly title self-custodied Bitcoin in a joint revocable trust:

  1. Document the transfer in writing. Create a signed assignment of property that states: "We, John Smith and Jane Smith, hereby assign and transfer all Bitcoin held at the following addresses [list wallet addresses or xpubs] to The Smith Family Trust dated January 15, 2026." Both spouses sign.
  2. Update your trust's schedule of assets. The trust should include a Schedule A (or equivalent) listing assets held in the trust. Add the Bitcoin with wallet addresses or identifiers.
  3. Ensure both trustees have access. If the trust names both spouses as co-trustees, both must be able to access the Bitcoin. This means either sharing seed phrase access (secured in a safe deposit box, fireproof safe, or multi-location backup) or implementing a multi-signature wallet where both spouses hold keys.
  4. Document seed phrase location and access. The trust's ancillary documents (often called a "letter of wishes" or "digital asset memorandum") should describe where the seed phrase is stored and how the successor trustee accesses it — without including the seed phrase itself in the trust document, which becomes a public record at probate.

Critical warning: Never put your seed phrase in the trust document itself. Trust documents can become public records. A separate, securely stored digital asset memorandum is the correct approach.

Multi-Signature Wallets and Trust Structure

Multi-sig is the gold standard for trust-held Bitcoin. A 2-of-3 multi-sig configuration works well for a joint revocable trust:

  • Key 1: Spouse A
  • Key 2: Spouse B
  • Key 3: Estate attorney, institutional co-trustee, or secure backup location

During life, either spouse plus the other (or the backup key) can move funds. At first death, the surviving spouse plus the backup key can still access the Bitcoin. If both spouses are incapacitated, the successor trustee and the backup key holder can access it together.

This structure maps directly to how joint revocable trusts function legally: both spouses have authority during life, and the successor trustee steps in when both are gone.

The A/B Trust Structure Explained

The A/B trust is the workhorse of married-couple estate planning. It has been the standard approach for decades, and while recent tax law changes have reduced its necessity for smaller estates, it remains the optimal structure for Bitcoin holders with significant wealth.

How It Works

During both spouses' lifetimes, the joint revocable trust operates as a single entity. Both spouses are co-trustees. All assets — including Bitcoin — are held in one pool.

When the first spouse dies, the trust splits into two sub-trusts:

Trust A (Survivor's Trust or Marital Trust): Funded with the surviving spouse's share of the trust assets. The surviving spouse remains trustee and has full control. This trust remains revocable — the surviving spouse can amend it, spend the assets, or restructure it however they want.

Trust B (Bypass Trust or Credit Shelter Trust): Funded with an amount up to the deceased spouse's remaining federal estate tax exemption — currently $13.99 million per individual under the One Big Beautiful Bill Act of 2025 (OBBBA), effectively approximately $15 million when adjusted for inflation in 2026. This trust becomes irrevocable at the first spouse's death. The assets in Trust B are permanently outside the surviving spouse's taxable estate, no matter how much they appreciate.

Why This Matters for Bitcoin

Consider a married couple with $20 million in Bitcoin. The first spouse dies in 2026.

Without an A/B trust: All $20 million passes to the surviving spouse via the unlimited marital deduction. No estate tax at first death. But when the surviving spouse dies — if Bitcoin has appreciated to $60 million — the entire $60 million is in their estate. With a $15 million exemption, that is $45 million subject to estate tax at 40%, creating an $18 million tax bill.

With an A/B trust: At first death, $15 million goes into Trust B (the bypass trust). $5 million stays in Trust A with the surviving spouse. When the surviving spouse dies, Trust B — now worth perhaps $45 million due to Bitcoin appreciation — is completely outside their estate. Only Trust A (the surviving spouse's assets) is counted. If Trust A is worth $15 million or less, the surviving spouse's own exemption covers it. Total estate tax: zero.

The A/B trust effectively removes an entire branch of Bitcoin appreciation from the taxable estate. For an asset class with the appreciation potential of Bitcoin, this is not a marginal optimization — it is the difference between a multi-million dollar tax bill and no tax bill at all.

Trust B and the Surviving Spouse's Access

A common concern: does putting Bitcoin in Trust B mean the surviving spouse loses access? Not necessarily. Trust B can be drafted to give the surviving spouse:

  • Income from the trust (relevant if Trust B holds income-producing Bitcoin-related assets)
  • Distributions for health, education, maintenance, and support (the "HEMS" standard)
  • A 5-and-5 power: the right to withdraw the greater of $5,000 or 5% of trust assets annually

The surviving spouse cannot be the sole trustee of Trust B without risking inclusion in their estate. An independent co-trustee or sole independent trustee is typically required for distributions beyond the HEMS standard.

When A/B Trusts Still Make Sense Under OBBBA

The One Big Beautiful Bill Act permanently set the federal estate tax exemption at approximately $15 million per individual (indexed for inflation). For a married couple, that is roughly $30 million. Many advisors now argue that A/B trusts are unnecessary for couples below $30 million.

They are wrong — at least for Bitcoin holders. Here is why the A/B trust remains relevant even under the higher exemption:

1. Bitcoin Appreciation Destroys Portability's Value

Portability (discussed in detail below) only transfers the deceased spouse's unused exemption amount. It does not shelter the growth on those assets. If your Bitcoin doubles, triples, or increases tenfold between the first and second death, all that appreciation is in the surviving spouse's estate. An A/B trust locks the exemption amount into Trust B at first death, and all subsequent appreciation grows outside the estate. For full analysis, see our portability vs. bypass trust comparison.

2. State Estate Taxes Have Much Lower Exemptions

Twelve states and the District of Columbia impose their own estate taxes, many with exemptions far below the federal level:

State Estate Tax Exemptions (2026)
State Exemption Top Rate
Oregon$1 million16%
Massachusetts$2 million16%
Washington$2.193 million20%
Minnesota$3 million16%
New York$6.94 million16%
Illinois$4 million16%
ConnecticutMatches federal12%
Hawaii$5.49 million20%

If you live in Oregon with $5 million in Bitcoin, you are already well above the state exemption even if you are nowhere near the federal exemption. An A/B trust can shelter the deceased spouse's share from state estate tax. Most states do not recognize portability.

3. The Exemption Could Change Again

Congress has changed the estate tax exemption repeatedly over the past 25 years. It was $675,000 in 2001, $5 million in 2011, $11.7 million in 2021, and approximately $15 million in 2026 under OBBBA. While OBBBA made the higher exemption permanent, "permanent" in tax law means "until Congress changes it." An A/B trust built today protects against future legislative reductions.

4. Divorce Protection

If the surviving spouse remarries and later divorces, assets in Trust B are protected from the new spouse's claims. Assets the surviving spouse owns outright — including anything inherited without trust protection — could be at risk depending on state law and commingling.

5. Creditor Protection

Trust B, as an irrevocable trust, provides a degree of creditor protection that assets owned outright do not. For families with professional liability exposure (physicians, business owners, attorneys), this is a meaningful benefit.

Portability vs. A/B Trust: The Bitcoin Appreciation Problem

Since 2011, the surviving spouse has been able to use the deceased spouse's unused estate tax exemption through an election called portability. The executor files IRS Form 706 within nine months of death (with a possible six-month extension), and the Deceased Spouse's Unused Exclusion (DSUE) amount transfers to the surviving spouse.

Portability is simpler than an A/B trust. No sub-trusts to administer. No independent trustee to appoint. No annual trust accounting. For couples with moderate estates and traditional assets, portability is often sufficient.

For Bitcoin holders, portability has a critical flaw.

The Appreciation Problem

Portability transfers a fixed dollar amount — the deceased spouse's unused exemption. It does not create a separate trust that grows independently.

Example: First spouse dies in 2026 with $15 million in Bitcoin. They used none of their exemption, so $15 million in DSUE transfers to the surviving spouse via portability. The surviving spouse now has their own $15 million exemption plus the $15 million DSUE — $30 million total.

Sounds adequate. But here is the problem: the Bitcoin the surviving spouse inherited is still in their estate. If that $15 million in Bitcoin grows to $80 million by the surviving spouse's death, the estate is $80 million against a $30 million combined exemption. Estate tax on $50 million at 40% is $20 million.

With an A/B trust, $15 million goes into Trust B at first death. Trust B grows to $80 million. At the surviving spouse's death, Trust B is outside the estate entirely. The surviving spouse's own assets (Trust A) use the surviving spouse's own $15 million exemption. If Trust A is at or below $15 million, estate tax is zero.

Portability vs. A/B Trust: Bitcoin Appreciation Scenario
Scenario Portability Only A/B Trust
BTC at first death $15M → surviving spouse outright $15M → Trust B (bypass)
BTC value at second death $80M (in surviving spouse's estate) $80M (in Trust B, outside estate)
Combined exemption available $30M $15M (surviving spouse's only)
Taxable estate at second death $50M $0 (if Trust A ≤ $15M)
Federal estate tax $20M $0

The delta is $20 million. That is the cost of choosing simplicity over structure when you hold a high-appreciation asset.

When Portability Is Still Acceptable

Portability may be sufficient when the couple's total estate (including projected Bitcoin appreciation) is unlikely to exceed $30 million by the second death. If your current estate is $8 million and you do not expect it to exceed $25 million, portability keeps things simple without meaningful tax risk. But if you hold a concentrated Bitcoin position with a long time horizon, the appreciation math almost always favors the A/B trust.

QTIP Trust: The Flexible Middle Ground

The Qualified Terminable Interest Property (QTIP) trust is one of the most powerful tools available to married Bitcoin holders — particularly those in blended families or those who want to control the ultimate destination of their wealth while still qualifying for the unlimited marital deduction.

How the QTIP Works

The first spouse to die places Bitcoin (and other assets) in a QTIP trust. The surviving spouse receives all income from the trust for life and may receive principal distributions based on the trust terms. At the surviving spouse's death, the remaining assets pass to the beneficiaries the first spouse designated — typically children from a prior marriage.

The key features:

  • Marital deduction: QTIP trust assets qualify for the unlimited marital deduction, meaning no estate tax at first death regardless of amount
  • Control: The first spouse to die determines the ultimate beneficiaries — not the surviving spouse
  • Inclusion: QTIP assets are included in the surviving spouse's estate at second death (unlike Trust B in an A/B structure)
  • Flexibility: The executor can make a partial QTIP election, funding some assets into the QTIP and others into a bypass trust

QTIP for Bitcoin in Blended Families

Consider this scenario: John has two children from a first marriage and is now married to Sarah. John holds 50 BTC currently worth $5 million. He wants Sarah to be financially secure after his death but wants his Bitcoin to ultimately pass to his children — not to Sarah's future spouse or Sarah's separate beneficiaries.

Without a QTIP, John's options are limited. If he leaves the Bitcoin outright to Sarah, she can do whatever she wants with it — including leaving it to her own children, a new spouse, or spending it entirely. If he leaves it directly to his children, Sarah gets nothing and the marital deduction is lost.

The QTIP solves this: Sarah gets income from the Bitcoin (or access to principal under the trust terms) for her lifetime. She is protected. When Sarah dies, the remaining Bitcoin passes to John's children. John controlled the destination. Everyone is provided for.

Combining QTIP with A/B Structure

The most sophisticated approach combines both: at first death, the trust splits into Trust B (funded up to the exemption amount, bypass trust) and a QTIP trust (for the excess). This captures the estate tax benefit of the bypass trust while using the QTIP's marital deduction for anything above the exemption amount — and maintaining control over the ultimate beneficiaries of both portions.

Community Property States and the Double Step-Up Advantage

If you live in Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin, your state follows community property law. This creates a massive advantage for Bitcoin holders that most financial advisors underestimate.

The Community Property Step-Up

In common law states, when one spouse dies, only the deceased spouse's half of jointly held property receives a stepped-up basis. The surviving spouse's half retains its original cost basis.

In community property states, both halves of community property receive a stepped-up basis at the first spouse's death. This is IRC Section 1014(b)(6), and it is one of the most valuable provisions in the entire tax code for Bitcoin holders.

Example: A married couple in Texas purchased 100 BTC at $1,000 each — a total basis of $100,000. At the first spouse's death, the BTC is worth $10 million. In a common law state, only 50 BTC gets a step-up (new basis: $5 million). The surviving spouse's 50 BTC retains the $50,000 basis, creating a $4.95 million embedded capital gain. In Texas, all 100 BTC get a full step-up to $10 million. The embedded capital gain is completely eliminated.

At a 23.8% federal capital gains rate (20% plus 3.8% NIIT), that step-up saves $1.178 million in capital gains tax on $4.95 million of gain. On larger positions, the savings scale proportionally.

For a detailed state-by-state analysis, see our community property estate planning guide.

Implications for Trust Structure

The community property step-up has direct implications for how married Bitcoin holders should structure their trusts:

Joint revocable trusts preserve community property character. When both spouses hold Bitcoin in a single joint revocable trust, the community property characterization is maintained, and the full step-up applies at first death. This is the strongest argument for joint trusts in community property states.

Separate trusts can destroy community property character. If each spouse moves their "half" of community property Bitcoin into separate trusts without a proper community property agreement, the IRS may argue the property is no longer community property. The full step-up could be lost.

The workaround: if you want separate trusts in a community property state, your attorney must draft a community property agreement that explicitly maintains the community property character of assets even though they are held in separate trusts. This is doable but adds complexity and risk.

Bottom line for community property states: Unless you have a compelling reason for separate trusts (blended family, significant separate property), a joint revocable trust is almost always the better choice. The community property step-up is too valuable to risk.

Step-Up in Basis: Community Property vs. Common Law
Factor Community Property State Common Law State
Basis step-up at first death 100% of community property 50% (decedent's share only)
Example: 100 BTC, $100K basis, $10M FMV at death New basis: $10M (full) New basis: $5.05M (half)
Embedded capital gain for survivor $0 $4.95M
Tax savings at 23.8% $1.178M saved $0
Preferred trust structure Joint revocable trust Either (no step-up advantage)

Revocable vs. Irrevocable: Lifecycle Considerations

Every trust discussion eventually arrives at the revocable versus irrevocable question. For married Bitcoin holders, the answer is usually both — but at different stages of your financial life.

Revocable Trust: The Accumulation Phase

During your lifetime, a revocable trust provides:

  • Full control: You can amend, revoke, or restructure the trust at any time
  • Probate avoidance: Assets in the trust bypass the public, slow, expensive probate process
  • Incapacity planning: If you become incapacitated, the successor trustee manages your Bitcoin without needing a court-appointed conservatorship
  • No tax impact: The revocable trust is a "grantor trust" — it uses your Social Security number, files no separate return, and has no independent tax consequences

What a revocable trust does not provide:

  • Asset protection: Creditors can reach revocable trust assets as easily as assets you own outright
  • Estate tax reduction: Revocable trust assets are fully included in your taxable estate

For married couples actively accumulating Bitcoin, the revocable trust is the right starting point. You want flexibility. You want to be able to change beneficiaries, update key management procedures, and restructure as your Bitcoin position grows.

Irrevocable Trust: The Wealth Preservation Phase

As your Bitcoin position grows beyond your estate tax exemption, irrevocable structures become essential. An irrevocable trust removes assets from your taxable estate permanently. Once Bitcoin is in an irrevocable trust, it is no longer yours for estate tax purposes — even if it appreciates from $10 million to $500 million.

Common irrevocable structures for Bitcoin holders include:

  • Irrevocable Life Insurance Trust (ILIT): Holds a life insurance policy outside the estate to provide liquidity for estate tax payment
  • Spousal Lifetime Access Trust (SLAT): An irrevocable trust for the benefit of the other spouse — removes assets from the grantor spouse's estate while the beneficiary spouse retains access
  • Grantor Retained Annuity Trust (GRAT): Transfers future Bitcoin appreciation to beneficiaries with minimal or zero gift tax
  • Dynasty Trust: Multi-generational irrevocable trust designed to hold Bitcoin for descendants in perpetuity

The typical progression for married Bitcoin holders: start with a joint revocable trust in the accumulation phase. As the estate grows beyond $15–20 million, begin funding irrevocable structures to remove growth assets from the taxable estate. The revocable trust remains the command center — the irrevocable trusts are satellites that capture appreciation outside the estate.

Choosing a Successor Trustee for Bitcoin

When both spouses die or become incapacitated, the successor trustee takes over. For traditional assets, this is a straightforward role — call Fidelity, present the death certificate, manage the accounts. For Bitcoin, the successor trustee role is operationally critical and potentially catastrophic if handled incorrectly.

What the Successor Trustee Must Be Able to Do

  1. Access the Bitcoin. This means access to seed phrases, hardware wallet PINs, multi-sig keys, or custodian account credentials. If the successor trustee cannot access the Bitcoin, it is effectively lost — regardless of what the trust document says.
  2. Understand Bitcoin. A successor trustee who does not understand Bitcoin may make irreversible errors: sending to wrong addresses, falling for scams, failing to secure private keys, or inadvertently creating taxable events through unnecessary transactions.
  3. Work with custodians. If the Bitcoin is held at an exchange or qualified custodian, the successor trustee must navigate their procedures for trust account succession — which can involve legal review, compliance checks, and significant delays.
  4. Execute the distribution plan. The trust terms dictate how and when beneficiaries receive Bitcoin. The successor trustee must be able to execute distributions — whether that means transferring BTC on-chain to beneficiaries' wallets or liquidating to fiat for those who prefer cash.

Options for Successor Trustee

Successor Trustee Options for Bitcoin Trusts
Option Advantages Risks
Trusted family member Knows the family, low cost, available May not understand Bitcoin custody, security risk if holding seed phrases
Professional fiduciary / trust company Institutional controls, bonded, regulated Many traditional trust companies do not handle Bitcoin; fees of 0.5–1.5% annually
Bitcoin-native trust company Understands custody, multi-sig, on-chain operations Fewer options, less track record, counterparty risk
Co-trustee structure (family + institutional) Combines family knowledge with professional capability Higher cost, potential for trustee disagreements

The co-trustee structure — pairing a trusted family member with an institutional trustee that understands Bitcoin — is the approach we see most often among families with significant Bitcoin holdings. The family member provides context and personal judgment. The institutional trustee provides operational capability, regulatory compliance, and a check on conflicts of interest. For detailed guidance on selecting the right trustee, see our trustee selection guide.

The Seed Phrase Succession Plan

No matter who serves as successor trustee, there must be a documented, tested plan for transferring seed phrase access. The plan should address:

  • Where seed phrases are physically stored (and backup locations)
  • Who knows the locations (and who has access to vaults or safe deposit boxes)
  • What happens if a storage location is compromised
  • How the successor trustee verifies the integrity of the seed phrases before accessing the Bitcoin
  • Whether a dead man's switch or time-locked mechanism is in place for emergency access

Test this plan during your lifetime. Have the successor trustee actually go through the process of locating the seed phrase, accessing a test wallet, and confirming they can operate independently. A plan that has never been tested is not a plan — it is a hope.

The Bitcoin Trust Titling Checklist

The trust is drafted. The structure is chosen. Now comes the execution. This checklist covers every step required to actually move your Bitcoin and related assets into a joint revocable trust.

Step 1: Exchange and Custodian Accounts

  • Open a new trust account at each exchange or custodian where you hold Bitcoin (Coinbase, Swan, Gemini, Fidelity, etc.)
  • Provide the certificate of trust and any additional documentation the custodian requires (typically trustee identification, trust EIN if applicable, trust formation date)
  • Transfer Bitcoin from individual accounts to the new trust account
  • Confirm the transfer is complete and the individual account can be closed or zeroed
  • Document cost basis for each transfer — the basis carries over, but you need records

Step 2: Self-Custodied Bitcoin (Hardware Wallets)

  • Execute a signed assignment of property transferring Bitcoin at specified addresses to the trust
  • Update the trust's schedule of assets to include wallet addresses or other identifiers
  • If using single-sig: ensure both co-trustees (both spouses) have documented access to the seed phrase
  • If using multi-sig: ensure the key distribution aligns with trustee authority (e.g., 2-of-3 with both spouses and one backup)
  • Create a digital asset memorandum that describes access procedures for the successor trustee — store separately from the trust document

Step 3: Retirement Accounts (Do NOT Transfer Into Trust)

  • Do not title your IRA, 401(k), or other retirement account in the trust's name. This triggers a full taxable distribution. Retirement accounts cannot be held in a revocable trust.
  • Instead, update the beneficiary designation on your retirement accounts. Primary beneficiary: surviving spouse (or the trust, if there is a specific reason to use a conduit or accumulation trust structure). Contingent beneficiary: the trust.
  • If your retirement account holds Bitcoin (via a self-directed IRA or Bitcoin IRA), the same rule applies: update beneficiary designations, do not retitle.

Step 4: Pour-Over Will

  • Execute a pour-over will that directs any assets not already in the trust at death to be "poured over" into the trust
  • This catches any Bitcoin you acquired after the trust was funded but forgot to title in the trust's name
  • The pour-over will goes through probate, so it is a safety net — not a substitute for proper trust funding

Step 5: Documentation and Verification

  • Verify all exchange and custodian accounts are titled in the trust's name
  • Verify all self-custodied Bitcoin is documented in the schedule of assets
  • Verify retirement account beneficiary designations have been updated
  • Verify the digital asset memorandum is complete, current, and stored securely
  • Verify the successor trustee knows where to find the memorandum and has been briefed on the process
  • Schedule an annual review to confirm everything remains current — new Bitcoin purchases, new wallets, changed custody arrangements, updated seed phrase locations

Putting It All Together: Which Structure Is Right for You?

The decision tree for married Bitcoin holders reduces to a handful of questions:

Trust Structure Decision Matrix
Your Situation Recommended Structure
Community property state, first marriage, estate under $30M Joint revocable trust with A/B provisions (for state tax and appreciation protection)
Community property state, first marriage, estate over $30M Joint revocable trust with A/B provisions + irrevocable structures (SLAT, GRAT, dynasty trust)
Common law state, first marriage, estate under $30M Joint or separate revocable trust with portability (A/B optional based on appreciation expectations)
Common law state, first marriage, estate over $30M Separate revocable trusts with A/B provisions + irrevocable structures
Blended family, any state Separate revocable trusts with QTIP provisions to control ultimate beneficiaries
Significant separate property (pre-marriage Bitcoin) Separate revocable trusts to maintain separate property characterization
Bitcoin expected to appreciate 5x+ before second death A/B trust mandatory — portability alone will not capture the growth

No single structure is optimal for every couple. But for married Bitcoin holders with meaningful positions, the joint revocable trust with A/B provisions is the default starting point. From there, you add QTIP provisions for blended families, irrevocable structures for estates above $30 million, and community property preservation strategies for couples in the nine community property states.

The one universal rule: do not postpone this. Bitcoin's volatility and appreciation potential mean that an estate plan that was adequate at $5 million in Bitcoin may be catastrophically insufficient at $50 million. Build the structure now, while you have the flexibility to do it on your terms.
