Bitcoin Executor Legal Responsibilities and Access Constraints

Executor Fiduciary Duties for Bitcoin Assets

This memo is published by CustodyStress, an independent Bitcoin custody stress test that produces reference documents for individuals, families, and professionals.

What an Executor Is

An executor receives letters testamentary from the court. The letters grant authority over the deceased's estate. The estate includes Bitcoin. The executor has legal power over the Bitcoin. The executor cannot move it. The private keys are unknown. The hardware wallet is locked. The seed phrase backup is missing.

The executor holds authority. The executor lacks capability. Bitcoin executor responsibilities legal obligations attach to the asset regardless of whether the executor can reach it. This memo describes how legal responsibility and technical access operate independently in bitcoin estate administration.

What an Executor Is

An executor is the person named in a will to handle the deceased's estate. The probate court confirms this role by issuing letters testamentary. These letters give the executor legal authority to act on behalf of the estate.

The executor's job includes several tasks. Identify assets. Protect assets. Pay debts and taxes. Distribute what remains to beneficiaries. Account for all actions taken. The executor acts as a fiduciary—someone who handles another person's property with a duty of care.

Bitcoin fiduciary duty estate planning concepts apply here. The executor owes duties to the estate and its beneficiaries. These duties exist because the executor holds a position of trust, not because the executor has physical control over assets.

---

How Legal Authority Attaches

Legal authority attaches to assets through legal process. The deceased owned Bitcoin. The will names an executor. The court confirms the executor. The executor now has legal authority over everything the deceased owned—including the Bitcoin.

This attachment happens through documents and court orders. It does not require physical possession. It does not require technical access. It does not require the ability to move or control the asset. The authority exists because the law says it exists.

An executor has legal authority over a bank account even before obtaining login credentials. An executor has legal authority over a house even before receiving the keys. An executor has legal authority over Bitcoin even before locating the private keys. Authority precedes access.

---

How Technical Access Works for Bitcoin

Technical access to Bitcoin works differently than legal authority. Technical access requires the ability to sign transactions. Signing transactions requires private keys. Private keys exist as data—on devices, in backups, or in memory.

Legal documents do not produce private keys. Court orders do not produce private keys. Letters testamentary do not produce private keys. The legal system operates on documents and authority. The Bitcoin network operates on cryptographic keys.

An executor with full legal authority over an estate cannot move Bitcoin without the private keys. The authority exists. The capability does not. These are separate systems with no automatic bridge between them.

---

The Gap Between Authority and Capability

A gap exists between legal authority and technical capability. The executor has authority over the Bitcoin. The executor may or may not have capability to access it.

The gap varies by situation. Sometimes the gap is small. The deceased left clear instructions. The seed phrase is in a known location. The executor can follow the steps and access the Bitcoin. Authority and capability align.

Sometimes the gap is large. No instructions exist. No seed phrase is found. The hardware wallet requires a PIN no one knows. The executor has complete authority and zero capability. Authority and capability diverge entirely.

The size of the gap depends on the custody system the deceased used. The gap is not under the executor's control. The executor inherits whatever situation the deceased created.

Duties That Attach Regardless of Access

Bitcoin executor responsibilities legal duties attach to the role, not to access capability. Certain duties apply whether or not the executor can reach the Bitcoin.

Duty to identify assets: The executor has an obligation to determine what the estate contains. If Bitcoin exists, the executor is expected to identify it. This duty applies even if the executor cannot access the Bitcoin after identifying it.

Duty to preserve assets: The executor has an obligation to protect estate assets from loss or waste. For Bitcoin, this may involve securing devices, protecting backup materials, or preventing unauthorized access by others. This duty applies even if the executor cannot move the Bitcoin.

Duty to account: The executor has an obligation to report to the court and beneficiaries about estate assets and administration. Bitcoin appears in accountings whether or not it can be distributed. The duty to account exists independently of access.

---

Accounting for Inaccessible Assets

Estate administration involves accounting. The executor reports what the estate contains, what happened to it, and what remains. Beneficiaries and courts review these accountings.

Bitcoin that cannot be accessed still appears in accountings. The executor reports: the estate includes Bitcoin at this address with this approximate value. The executor also reports: access to this Bitcoin has not been achieved. The accounting reflects reality—the asset exists, the access does not.

Inaccessible assets create complexity in accounting. The value is known or estimable. The asset belongs to the estate. Distribution to beneficiaries is blocked. The accounting captures this situation without resolving it.

---

Preservation Without Control

The duty to preserve assets creates tension when the executor cannot control the asset. Bitcoin sitting in a wallet the executor cannot access is still an estate asset. The executor has a duty to preserve it. Preservation without control occurs through indirect means.

The executor preserves by protecting related materials. The hardware wallet is kept in a controlled location. Documents that might contain recovery information are protected. Devices that might hold keys are not discarded or wiped.

The executor preserves by preventing interference. Other parties are informed that the Bitcoin belongs to the estate. Unauthorized access attempts are documented. The executor's authority over the asset is asserted even without capability to control it.

Preservation without control is imperfect. The executor cannot prevent the Bitcoin from losing value. The executor cannot prevent technical failures in custody systems. The executor can only protect what is within reach—the physical materials and information related to the Bitcoin.

---

Distribution Blocked by Access Constraints

The executor's job includes distributing assets to beneficiaries. Distribution of Bitcoin requires the ability to move it. If access is constrained, distribution is blocked.

A beneficiary is entitled to receive Bitcoin under the will. The executor cannot deliver it. The entitlement exists. The delivery does not. The beneficiary has a legal right to an asset the executor cannot transfer.

Blocked distribution creates an incomplete estate. The estate remains open. The executor cannot close administration until assets are distributed or otherwise resolved. Bitcoin that cannot be accessed leaves the estate in a suspended state.

The executor's duty to distribute persists. The executor's ability to fulfill that duty is constrained by technical reality. The duty and the constraint exist simultaneously.

---

Time and Ongoing Obligations

Estate administration takes time. Bitcoin executor responsibilities legal obligations persist throughout the administration period. The executor remains responsible for the Bitcoin while attempts to access it continue.

Time affects the Bitcoin in ways the executor cannot control. The market price changes. The custody technology ages. The people who might help with access become harder to reach. The executor watches these changes while holding responsibility for the asset.

Ongoing obligations include monitoring and effort. Access information may remain undiscovered over extended periods. Technical experts may become involved during access attempts. The executor may need to pursue legal remedies against parties who hold keys. The obligations extend as long as the estate contains the Bitcoin.

---

When Access Is Partially Achieved

Access is not always all or nothing. The executor may achieve partial access—reaching some Bitcoin but not all.

The deceased held Bitcoin on an exchange and in self-custody. The exchange has a death claims process. The executor completes it. The exchange-held Bitcoin becomes accessible. The self-custody Bitcoin remains locked. The executor has achieved partial access.

Partial access means partial distribution. The executor distributes what can be reached. The executor accounts for what cannot be reached. Responsibilities continue for the inaccessible portion. The estate remains open for that portion.

Bitcoin fiduciary duty estate planning considerations apply to both portions. The executor administers the accessible Bitcoin under fiduciary standards. The executor also has ongoing responsibility for the inaccessible Bitcoin—preserving materials, documenting efforts, and accounting for its status.

---

Documentation of Efforts

Executors operating under access constraints face scrutiny. Beneficiaries may question why Bitcoin was not distributed. Courts may ask what efforts were made. Documentation becomes important.

The executor documents what was attempted. Searches for seed phrases. Attempts to unlock devices. Consultations with technical experts. Communications with exchanges or service providers. Each effort is recorded.

The executor documents what was found. Materials located. Information gathered. Partial progress made. Obstacles encountered. The documentation creates a record of the executor's actions.

Documentation does not create access. It creates evidence of diligence. The executor's record shows what was done to fulfill responsibilities under constrained conditions.

---

The Position of the Executor

The executor occupies an uncomfortable position. Legal responsibility exists. Technical capability may not. The executor is accountable for an asset that may be unreachable.

This position is not chosen. The executor accepted the role based on what was known. The access constraints may have been unknown at that time. The deceased may not have disclosed the custody arrangement. The executor discovers the constraints after accepting the role.

The position persists until resolved. The responsibility remains attached to the executor role. The executor cannot disclaim the Bitcoin simply because it is inaccessible. The duties remain attached to the role until the estate is closed—and the estate may remain open precisely because the Bitcoin cannot be distributed.

---

Access Constraints Do Not Negate Responsibility

Access constraints explain why distribution has not occurred. They do not negate the executor's responsibility for the asset. The executor remains responsible for Bitcoin that cannot be accessed.

Responsibility without access means the executor holds accountability without control. The executor is described as undertaking efforts within constrained conditions. The executor is expected to preserve what can be preserved. The executor is expected to account for the asset's status. These expectations persist regardless of access.

The constraint is technical. The responsibility is legal. The two exist in different domains. A technical constraint does not cancel a legal obligation. The obligation continues. The constraint explains why the obligation cannot be fully performed.

---

Assessment

Bitcoin executor responsibilities legal obligations attach to the role of executor through legal process. These obligations exist whether or not the executor has technical capability to access or move the Bitcoin. Legal authority and technical access operate independently.

Executors face duties to identify, preserve, account for, and distribute estate assets. When access to Bitcoin is constrained, these duties persist in modified form. The executor preserves related materials, documents efforts, accounts for the asset's status, and continues attempts to achieve access.

Bitcoin fiduciary duty estate planning principles apply throughout. The executor holds a position of trust and responsibility for assets that may be beyond technical reach. Access constraints do not negate the existence of executor duty—they describe the conditions under which that duty operates.
