How to Put Bitcoin in a Trust: A Step-by-Step Guide

Work with a qualified estate planning attorney to draft a revocable living trust. Do not use a generic trust template from an online service — standard templates drafted before the digital asset era lack the provisions necessary for Bitcoin. The trust document must explicitly authorize the trustee to hold, manage, invest in, and transfer digital assets including Bitcoin. It must also include RUFADAA-compliant language granting the trustee fiduciary access to digital assets — particularly critical for self-custodied Bitcoin where there is no online custodian "tool" granting access.

The trust should also address: whether the trustee can engage a professional Bitcoin custodian, how Bitcoin custody decisions are made (directed trust provisions if applicable), and what happens to the Bitcoin holdings during any period of trustee incapacity or transition.

If you already have a revocable living trust, review it carefully. If it was drafted before approximately 2018, there is a high probability it contains no digital asset provisions at all. Work with your attorney to amend the trust with a digital asset addendum that adds: (1) explicit authority to hold and transact in Bitcoin and other digital assets, (2) RUFADAA authorization language, (3) trustee authority to engage a qualified Bitcoin custodian or co-trustee with digital asset expertise, and (4) reference to the Letter of Instruction described in Step 3.

This amendment does not require re-executing the entire trust — a properly drafted and executed trust amendment is sufficient. Your attorney can advise on the execution requirements in your state.

A Letter of Instruction is a private, non-legal document that provides your successor trustee with the operational information needed to access and manage your Bitcoin after your death or incapacity. Unlike the trust document — which may be seen by attorneys, courts, or beneficiaries — the Letter of Instruction is kept in a secure location and shared only with your trustee and relevant parties.

The Letter of Instruction should include: a description of your Bitcoin custody arrangement (hardware wallet make/model, exchange accounts, custodian name), the wallet addresses or account identifiers (not the seed phrase itself), the location of your seed phrase backup and hardware devices, the name and contact information of any custody advisor or technical specialist your trustee should engage, and a clear statement that the Bitcoin holdings are held on behalf of and owned by the trust.

Execute a formal trust assignment — a legal document stating that you assign your Bitcoin holdings to yourself in your capacity as trustee of the trust. The language is typically: "I, [Your Name], hereby assign and transfer all right, title, and interest in the Bitcoin holdings described in the attached schedule to myself as Trustee of the [Trust Name], for the benefit of the trust and its beneficiaries."

For exchange-custodied Bitcoin (Coinbase, Gemini, etc.): contact the custodian to update the account registration to reflect trust ownership. Many qualified custodians have formal procedures for this. For self-custodied Bitcoin: no on-chain transfer is required. The assignment document and your estate plan documentation together establish the trust's legal ownership of the beneficial interest in those coins — the coins themselves stay in your wallet.

Document the wallet addresses and approximate holdings in a schedule attached to the assignment. Keep this schedule updated as holdings change.

The most technically correct trust structure fails if your successor trustee doesn't know it exists, doesn't know how to access the Bitcoin, or doesn't have the technical competence to act when the time comes. Trustee preparation is not optional.

Steps for trustee preparation include: (1) Inform your successor trustee that they are named and explain their responsibilities generally — they don't need a full technical education, but they need to know the plan exists. (2) Walk them through the Letter of Instruction: where it is, what it contains, and how to access it. (3) Provide at least basic technical orientation on Bitcoin custody — what a hardware wallet is, why the seed phrase matters, and why they should not attempt to access the wallet without professional help if they are not technically sophisticated. (4) Identify a Bitcoin custody specialist or advisor they can engage if needed. (5) Store contact information for your estate attorney and any technical advisors in the Letter of Instruction so the trustee has a clear path forward.

If your successor trustee is not technically capable of managing self-custodied Bitcoin, consider whether the trust should be amended to require transfer to a professional custodian upon your incapacity or death — or whether the trust's directed trustee provisions should designate a technical advisor who manages custody decisions.

Bitcoin estate planning is not a one-time exercise. Your holdings change. Custody technology changes. The law changes. Your family circumstances change. Review your trust documents, Letter of Instruction, and custody arrangement at least annually — and immediately after any of the following events: a significant change in your Bitcoin holdings, a change in your custody setup (new hardware wallet, change of custodian, new multi-sig arrangement), a change in beneficiaries or trustee designations, a significant change in your state's digital asset fiduciary law, and any major change in federal estate tax law.

At each review, confirm that the Letter of Instruction accurately reflects your current custody arrangement, that your successor trustee's contact information is current, and that the trust assignment schedule reflects your current holdings.
