Bitcoin Guardianship Document

Guardianship and Custody Access Preparation

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

Types of Guardianship

When minor children may inherit bitcoin, questions arise about how a bitcoin guardianship document functions and what legal structures protect minors' cryptocurrency interests. Minors cannot legally manage their own property. Someone must manage assets on their behalf until they reach adulthood. How bitcoin custody interacts with guardianship law creates complications that traditional assets do not present.

Guardianship involves court oversight, fiduciary duties, and reporting requirements. Self-custody bitcoin involves key management, security practices, and technical expertise. These domains intersect awkwardly. The legal framework for protecting minors' property was not designed with cryptocurrency in mind.

Types of Guardianship

Legal terminology distinguishes between guardianship of the person—responsibility for the child's care and upbringing—and guardianship of the estate—responsibility for managing the child's property. The same person may serve both roles, or different people may serve each role separately.

Guardian of the person makes decisions about where the child lives, their education, healthcare, and daily needs. This role does not directly involve managing bitcoin but matters for overall planning when parents name guardians for their children.

Guardian of the estate manages property belonging to the minor. If a child inherits bitcoin, the guardian of the estate has responsibility for that bitcoin. Court appointment, bonding requirements, and reporting obligations typically apply. The guardian manages assets for the child's benefit until the child reaches majority.

Conservator is a term some jurisdictions use instead of or alongside guardian for property management. Terminology varies by state. The function—managing a minor's property under legal oversight—remains similar regardless of the specific title used.

Court Involvement and Oversight

Guardianship of minors' estates typically involves court supervision. This oversight exists to protect children from mismanagement or exploitation of their assets. For bitcoin, court oversight creates complications that traditional assets do not present.

Inventories may need to be filed with the court listing the child's assets. Bitcoin held in self-custody appears on these inventories, creating a public record of holdings. The privacy that self-custody may have provided during the parent's lifetime disappears when holdings become court records.

Accountings may require periodic reporting on asset status. Courts may want to see valuations, transaction records, and explanations of management decisions. For bitcoin, this means documenting custody practices, explaining valuation methods, and potentially justifying decisions to hold rather than sell.

Approval requirements may apply to significant transactions. Selling bitcoin, changing custody arrangements, or making major decisions about the child's property may require court permission. The time needed to obtain approval may conflict with bitcoin's volatility or security considerations.

Guardian Capability Questions

Courts appoint guardians. The person appointed to manage a child's estate may or may not have any experience with cryptocurrency. Their legal authority to manage bitcoin coexists with potential practical inability to manage it.

Technical competence is not a standard appointment criterion. Courts evaluate factors like relationship to the child, trustworthiness, and financial stability—not cryptocurrency expertise. A guardian with excellent qualifications for traditional assets may be wholly unprepared for bitcoin.

Learning curves present challenges. A guardian who must learn cryptocurrency custody while also navigating guardianship requirements faces double complexity. The time needed to develop competence may leave bitcoin poorly managed during the learning period.

Delegation authority varies. Whether the guardian can hire cryptocurrency specialists to assist depends on court rules and the guardianship arrangement. Some jurisdictions require court approval for professional fees. Others give guardians more discretion. The guardian who cannot delegate faces problems if they lack personal capability.

Alternative Structures to Guardianship

Guardianship is not the only way to manage assets for minors. Alternative structures may avoid some guardianship complications while providing their own frameworks for protecting children's interests.

Trusts can hold assets for minor beneficiaries with trustees managing on their behalf. A trust for a minor can hold bitcoin with a trustee chosen for cryptocurrency capability rather than appointed by a court. Trust management avoids guardianship court oversight but requires trust creation during the parent's lifetime.

Custodial accounts under the Uniform Transfers to Minors Act (UTMA) or similar statutes provide another mechanism. A custodian manages assets for the minor until they reach the statutory age (which varies by state). UTMA accounts may or may not accommodate self-custody bitcoin depending on how custodianship works in practice.

Testamentary trusts can be created by will to receive assets for minor beneficiaries. Rather than passing bitcoin directly to a child—triggering guardianship requirements—the will directs bitcoin into a trust that manages it until the child reaches a specified age. This approach requires forethought during estate planning.

---

Custody Mechanics Under Guardianship

If a guardian manages self-custody bitcoin for a minor, the practical mechanics of custody create questions that guardianship law does not directly answer.

Key custody transfers authority without institutional intermediary. When the guardian takes over, they need access to keys. This transfer happens outside any operational framework. The guardian simply gains the same technical access the parent had—nothing more formal than that.

Security practices become the guardian's responsibility. Whatever security the parent maintained, the guardian must continue or replace. If the guardian lacks security knowledge, the bitcoin may become less protected under guardianship than it was before.

Documentation for court reporting may not exist. The parent may not have maintained records in formats courts expect. Creating proper documentation after the fact adds burden to an already complex situation. The guardian must reconstruct what the parent may never have formally documented.

---

Duration and Transition

Guardianship of minors' estates ends when the child reaches adulthood. At that point, remaining assets transfer to the now-adult child. For bitcoin, this transition has practical dimensions that legal termination of guardianship does not address.

Asset transfer at majority gives the child full control. Whatever bitcoin remains transfers to their direct custody. Whether the child is prepared to manage bitcoin themselves—at age 18 or 21 depending on jurisdiction—is not a factor in the legal transition.

Capability of the young adult may not match custody requirements. An 18-year-old who inherits bitcoin may not have the knowledge to manage it. The legal transition of authority does not create capability. What the parent intended may not match what the child can actually handle.

Extended management may be possible through trusts but not through guardianship. Guardianship ends at majority by operation of law. If the parent wanted bitcoin management to continue beyond age 18, guardianship cannot accomplish that—but a trust structure could.

---

Documentation Considerations

Parents planning for minor children's potential bitcoin inheritance face documentation questions about how to set up what guardians or trustees will need.

Naming preferences matters but courts make final decisions. Parents can indicate who they want as guardian of their children's estate, but courts ultimately decide based on the child's interests. The person named may not serve. Planning that depends entirely on one specific guardian serving may fail if someone else is appointed.

Technical documentation helps whoever ends up managing. Regardless of who serves as guardian or trustee, they need custody information. Documentation that enables any competent person to manage the bitcoin—not just a specific named individual—provides more robust protection.

Instructions about management preferences can guide fiduciaries. Whether to hold bitcoin, convert to traditional assets, use particular custody approaches—parents' preferences can be documented. These preferences may not be binding but inform fiduciary discretion.

---

Institutional Custody Considerations

Guardians managing bitcoin for minors face choices about custody approaches. Self-custody that worked for the parent may not work for the guardian. Institutional custody may simplify management but introduce different considerations.

Court comfort with institutional custody may exceed comfort with self-custody. Courts familiar with traditional financial institutions may find regulated custodians easier to supervise than self-custody arrangements. Reporting and accounting may be simpler with formal records.

Counterparty risks of institutional custody affect the child's assets. If a custodian fails, the child's bitcoin may be at risk. Guardians choosing institutional custody take on responsibility for custodian selection and ongoing due diligence.

Costs of institutional custody reduce the child's inheritance. Custody fees accumulate over years of guardianship. For smaller bitcoin holdings, fees may consume substantial portions of the asset. Guardians face tradeoffs between management simplicity and cost efficiency.

---

Planning Gaps

Many parents holding bitcoin have not considered what happens if their children inherit as minors. This planning gap leaves difficult questions unaddressed until they become urgent problems.

Default outcomes may not match intentions. Without planning, bitcoin passes according to intestacy or general will provisions, potentially into guardianship with court oversight and a guardian who lacks cryptocurrency knowledge. The parent's intent for how bitcoin would be managed may bear no resemblance to what actually occurs.

Surviving parent scenarios differ from both-parents-deceased scenarios. If one parent survives, they typically manage the child's inheritance without guardianship. Planning that assumes both parents' deaths may not address the more common scenario where one survives.

Ages of children affect planning needs. A 17-year-old who will reach majority in a year presents different considerations than a 2-year-old who will need management for sixteen years. Planning that addresses current ages may need updating as children grow.

---

Outcome

Bitcoin guardianship document considerations arise when minor children may inherit cryptocurrency. Guardianship of minors' estates involves court oversight, reporting requirements, and fiduciary duties designed for traditional assets. These requirements interact awkwardly with self-custody bitcoin, which involves key management and technical expertise that guardian appointment does not evaluate.

Alternative structures like trusts and custodial accounts may avoid some guardianship complications while providing different frameworks for protecting minors' interests. Guardian capability, custody mechanics, transition at majority, and documentation all present challenges that parents planning for minor heirs must consider.

Many parents have not addressed what happens if children inherit bitcoin while still minors. Default outcomes may not match intentions. Planning that considers guardianship versus trust structures, guardian capability, and documentation needs helps avoid leaving difficult questions for others to answer during grief and transition.
