Cryptocurrency Estate Planning Pitfalls in Missouri

What Happened

A Kansas City-area estate planning law firm published an analysis in August 2026 highlighting the growing risks cryptocurrency owners face when they fail to integrate digital assets into their estate plans. The piece, authored by an Overland Park attorney, draws attention to a fundamental difference between cryptocurrency and traditional financial assets: there is no institution standing between an owner and permanent loss of their holdings.

Unlike bank accounts or brokerage portfolios, cryptocurrency ownership depends entirely on private keys and recovery phrases known only to the owner. No court order, no perfectly drafted will, and no family relationship can unlock a crypto wallet without those credentials. The article cites a May 2026 InvestmentNews report describing cryptocurrency as an estate planning "nightmare" for precisely this reason. When an owner dies or becomes incapacitated without sharing access information, the digital assets can become permanently inaccessible.

The article identifies four core action areas for crypto owners: building a detailed inventory of digital holdings, updating powers of attorney to cover digital asset management, keeping estate planning documents current as holdings change, and storing access credentials securely outside of any documents that enter the public record during estate administration. The piece frames these not as optional steps but as essential components of any comprehensive estate plan that includes digital assets.

What It Means

For Missouri residents, the cryptocurrency estate planning challenge intersects with the state's existing legal framework in several important ways. Missouri has adopted the Uniform Trust Code, giving trustees broad authority to manage trust assets, including digital holdings. A properly drafted trust can grant a successor trustee explicit authority over cryptocurrency, Bitcoin, Ethereum, NFTs, and other blockchain-based assets. Without that explicit language, a trustee may lack clear legal standing to access or liquidate digital holdings on behalf of beneficiaries.

Missouri's financial power of attorney framework adds another layer of complexity. Missouri requires notarization for a financial power of attorney to be recognized. The state has not adopted the Uniform Power of Attorney Act, which means Missouri agents operate under a distinct statutory framework. A power of attorney that does not specifically address digital assets and cryptocurrency may leave an agent without the authority to manage those holdings during a period of incapacity. Given that incapacity can strike without warning, updating existing powers of attorney to include explicit digital asset language addresses a real and immediate risk.

Missouri's probate process creates a separate concern around security. Standard probate proceedings in Missouri typically run 12 monthsRSMo § 473.023Verified Jul 14, 2026View source to 18 monthsRSMo § 473.023Verified Jul 14, 2026View source, during which time certain documents enter the public record. Attorney fees in Missouri follow a statutory schedule ranging from 5%RSMo § 473.153(3) (statutory minimum: 5% first $5K, 4% next $20K, 3% next $75K, 2.75% next $300K, 2.5% next $600K, 2% over $1M; where reasonable compensation exceeds the minimum the court shall allow additional compensation — extraordinary services not required).

Estates that pass through probate expose details about asset holdings to public view, which is exactly why the source article warns against storing private keys or recovery phrases in wills or other documents that courts may receive. A funded revocable trust keeps those proceedings private and gives the successor trustee immediate authority without court involvement. Missouri's small estate affidavit procedure offers a simplified path for estates under $40,000§ 473.097Verified Jul 14, 2026View source, but cryptocurrency holdings that fluctuate in value can easily push an estate above that threshold unexpectedly. Missouri also recognizes transfer-on-death deeds for real property, a reminder that beneficiary-designation tools exist across asset classes, though cryptocurrency requires a different approach entirely.

Missouri does not impose a state estate tax or inheritance tax, which means Missouri families owe no state-level death tax regardless of estate size. At the federal level, the estate tax exemption currently stands at $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Jul 13, 2026View source per individual, meaning most families face no federal estate tax liability either. However, cryptocurrency's potential for rapid appreciation means owners with substantial holdings could approach federal thresholds faster than they anticipate. Capital gains treatment for cryptocurrency held by individuals differs from treatment at the estate or trust level. Missouri provides a 100% exclusion of long-term capital gains from state income tax for individuals, but that exclusion does not extend to estates or trusts, a distinction that affects how and when a trustee liquidates crypto holdings after a grantor's death. Assets inherited through an estate generally receive a step-up in basis to reset to fair market value on the date of death26 USC § 1014Verified Jul 13, 2026View source, which can eliminate embedded gains on appreciated cryptocurrency, though the rules around this benefit are complex and subject to change.

The security dimension the source article raises deserves particular attention in the Missouri context. Holographic wills — handwritten, unwitnessed documents — are not recognized in Missouri. This matters because some crypto owners informally jot down recovery phrases alongside handwritten notes they intend as estate planning documents. In Missouri, such documents carry no legal weight as wills, and embedding sensitive credentials in any document that might enter the probate record creates a theft risk. Missouri wills require 2RSMo § 474.320Verified Jul 15, 2026View source witnesses to be properly executed, and a self-proving affidavit allows the will to be admitted to probate without additional witness testimony. Neither feature solves the cryptocurrency access problem, which is why practitioners increasingly recommend storing credentials in a sealed envelope held by a trusted party or a secure vault, with only a reference to that location appearing in the estate plan itself.

Context from SimplyTrust

SimplyTrust's trust documents include legal provisions for cryptocurrency and blockchain-based assets, giving successor trustees defined authority over digital holdings. The framework covers when to sell, whether to distribute as cryptocurrency or convert to cash, and how to handle the unique security requirements these assets present. Sensitive credentials like private keys and seed phrases belong outside the trust document itself, with only a reference to their secure location appearing in the plan. Readers interested in understanding how digital assets fit into a broader estate plan can explore the guide to including digital assets in trusts and the overview of building a complete estate inventory, which covers financial accounts, real estate, and digital holdings alike.

For Missouri families navigating probate concerns, the overview of how trusts help avoid probate explains why a funded trust keeps asset details private and transfers authority to a successor trustee without court involvement. Those new to the broader concepts can start with the estate planning glossary, which covers the terminology that appears throughout digital asset and trust planning discussions. Missouri residents who own cryptocurrency and have not yet reviewed their powers of attorney, trust documents, or beneficiary designations hold an estate plan that may not reflect the full scope of their assets — a gap that carries real consequences for the people they intend to benefit.
