Crypto and Digital Assets in Your Estate Plan: Keys, Custody, and Not Losing It All

Cryptocurrency breaks the quiet assumption underneath every traditional estate plan: that an institution holds the asset and a court order can reach it. Self-custodied crypto has no institution — whoever holds the keys holds the coins, and keys that die with the owner take the assets with them permanently. Estimated billions in Bitcoin are already unrecoverable this way. The plan therefore has two halves. The legal half: wills and trusts that explicitly cover digital assets; fiduciary access powers under the digital-assets statutes most states have adopted (RUFADAA-based [LEGAL REVIEW]) so executors can lawfully reach accounts; and titling decisions — moving significant holdings into a trust raises real questions (how does a trustee custody keys? exchange accounts in trust name?) that planners now have real answers for, including institutional digital-asset custodians for scale. The operational half — where crypto plans actually fail: an access architecture the fiduciary can execute: an inventory of assets and where they live (exchanges, wallets, cold storage), key/seed-phrase storage that is neither in the will (public in probate!) nor a single point of failure — the toolkit runs from bank-vault instructions to multisignature arrangements and dead-man switches — and a named, technically capable person the executor can call, because the average fiduciary cannot safely move cold storage, and a panicked one is a security risk.

The tax memory problem

Basis records for assets bought across years of exchanges make the executor's (and the heirs') tax lives possible; estates that inherit coins without records inherit an accounting archaeology project. And the step-up at death applies to crypto like other property — which makes documented date-of-death valuation part of the fiduciary checklist.
