Crypto estate planning is the work you do while you are alive so somebody else can find, reach, value, and transfer your digital assets once you cannot. Two halves have to hold at the same moment: legal authority to act, and technical access to sign. In the families I have watched go through this, the legal half is handled competently and the access half is left to memory.
Part of our guide: Crypto Estate Planning.
The short version
- A plan has to deliver authority and access together. Either one alone produces nothing.
- Above the federal filing threshold the estate owes a defensible valuation on a deadline, which makes records part of the plan rather than an afterthought.
- Four instruments do the real work: will, revocable trust, durable power of attorney, and a private letter of instruction.
- Entities and trusts settle who owns the assets. Neither one moves a coin.
- The plan gets tested exactly once, by someone who was not in the room when you built it.
Two conditions, both required
Authority is what the documents grant. A personal representative appointed under a will, a successor trustee named in a trust, an agent under a durable power of attorney: each holds a legal right to deal with property on your behalf or on behalf of your estate.
Access is whether the holder of that authority can produce a valid signature. For assets at a regulated custodian, authority is usually enough, because the custodian has an onboarding process for fiduciaries and will honor documents. For self-custodied assets there is no such process. The network does not read letters of appointment. Whoever holds the key material controls the asset, and no court order changes that fact.
This is the structural difference between digital assets and everything else in an estate. A house has a recorder of deeds. A brokerage account has a transfer agent. A wallet has nobody to present paperwork to.
State law now recognizes the property side of this squarely. Wyoming’s digital asset statutes classify digital assets as property within the Uniform Commercial Code and set out how control is established, which gives a fiduciary a clearer legal footing than existed a decade ago (Wyo. Stat. Ann. §§ 34-29-101 to 34-29-102). Legal footing still does not produce a signature.
What the filing threshold changes
For families near or above the federal estate tax threshold, the plan acquires a second job with a hard deadline.
The IRS states the test plainly: a return is required
“if the gross estate of the decedent, increased by the decedent’s adjusted taxable gifts and specific gift tax exemption, is valued at more than the filing threshold for the year of the decedent’s death”
(IRS, Estate Tax). For decedents dying in 2026 that threshold is $15,000,000, up from $13,990,000 in 2025.
Three consequences follow, and they are the ones families underestimate.
The estate has to find the assets before it can report them. Nothing on a bank statement reveals a wallet. If the executor does not know an address exists, it does not appear on the return, and an omission discovered later is a worse problem than a difficult valuation.
Valuation has to be documented, not asserted. Digital assets trade continuously across venues that disagree. The estate needs a stated methodology and a record of the source, applied consistently to every holding.
The clock is short. Form 706 is due nine months after death, with a six-month extension available (IRS, About Form 706). Reconstructing a decade of transaction history inside that window, for a family that has just had a death, is the scenario worth planning to avoid.
Basis is the counterweight people forget while they are focused on the tax. Assets held until death generally receive a stepped-up basis; assets given away during life carry over yours. For a long-held position this cuts both ways, and the two effects should be modeled together rather than one at a time.
The four instruments that do the work
The will directs probate property and appoints the personal representative. Its weakness for this asset class is that a probated will can become a public record, so it should never contain keys, seed words, or the location of either.
The revocable trust avoids probate for assets it actually holds, keeps the arrangement private, and provides continuity on incapacity as well as death. Its weakness is that it only governs what was transferred into it, and crypto transfers are the ones most often skipped.
The durable power of attorney covers incapacity, which is statistically the likelier event and the one most plans treat as an afterthought. It should name digital assets explicitly.
The letter of instruction is the private operational document that tells a fiduciary what exists and where to look. It is not a dispositive instrument and it should never hold the secrets themselves. It holds the map.
The instruments answer who receives, who acts, and what exists. The access procedure is a separate design problem and it belongs to private key succession planning.
What net worth actually changes
Scale changes the shape of the problem in three specific ways.
Multiple structures. Once assets sit inside an LLC, a trust, or both, the estate has to trace ownership through the structure rather than to a person. That is an improvement when the records are clean and a serious complication when they are not.
Multiple custody arrangements. Larger holdings usually sit across a qualified custodian, one or more self-custodied wallets, and often a multi-signature arrangement. Each has a different access path and each needs its own successor procedure.
Concentration. A family whose wealth is concentrated in one volatile asset has a liquidity question the return will surface: if tax is owed, what gets sold, when, and who decides. Answering that in advance beats answering it in month seven.
What I actually see
The documents are drafted well and the funding never happens. A trust exists, the attorney did good work, and three years later the settlor still holds every coin in a personal wallet. The trust owns nothing.
The second pattern is the plan built around one person’s memory. Everything is known to the owner, nothing is written down, and the family’s entire position depends on that person being available and lucid. That is the exact circumstance the plan exists to survive.
The third is the estate that finds the assets and cannot value them. Exchange accounts closed years ago, transfers between wallets that look like sales, no basis records. The valuation work then costs more than careful record-keeping would have cost over the whole holding period.
The check I would run once a year takes an afternoon. List every asset the family holds. For each one, name the person who would reach it if you were unavailable tomorrow, and name the evidence that person could produce to show it belongs to the estate or the trust. Anything missing either answer is the plan’s real exposure.
Where this goes wrong
The failure is rarely the drafting. It is the gap between the document and the operational world it describes.
The specific failures: a seed phrase written into a will that becomes a public record. A trust that was never funded. A power of attorney silent on digital assets, so an agent has authority over everything except the largest holding. Custodian beneficiary designations that contradict the trust, since beneficiary designations override the will. An executor with full authority and no idea a hardware wallet exists. And basis records that vanished with an exchange account, leaving the estate to reconstruct a decade of history from block explorers.
The decision rule
- Inventory first. Every wallet, account, device, and entity, with what is in it. Without this nothing downstream can be accurate.
- Decide who holds authority in each scenario: death, incapacity, and temporary unavailability. Those are three different appointments.
- Choose the ownership layer deliberately, whether personal, entity, trust, or a combination, and write down why.
- Fund whatever you created. Transfer the assets and keep the record of the transfer.
- Design the access path separately, so authority and capability arrive together.
- Keep basis and valuation records continuously, because reconstruction after death is the expensive version.
- Reconcile the beneficiary designations at every custodian against the estate documents.
- Review annually and after any material change, including a new wallet, a new device, or a move to a different state.
Where this sits
Estate planning is the layer that decides what survives you. Trusts covers the instrument most often used to hold it. Wyoming LLCs covers the operating layer a trust commonly sits above. Custody covers whether anyone can reach the assets at all.
The families that get this right treat it as one coordinated design rather than four separate errands to four separate professionals. The estate attorney drafts, the CPA handles basis and the return, and somebody has to own the question of whether the custody arrangement and the documents actually describe the same thing. When nobody owns that question, it is the one that fails.
