Spouse Asks Who Else Knows About Bitcoin

Spousal Questions About Custody Knowledge Sharing

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

Why the Question Arises

The question comes during an ordinary conversation, perhaps prompted by news about someone who died with inaccessible bitcoin, or by general concern about what would happen in an emergency. A spouse asks who else knows about bitcoin—where it is, how to access it, what to do if something happens. The question seems simple. Answering it accurately proves more difficult than expected. The holder may realize they cannot give a satisfying answer, or may give an answer they later recognize as incomplete or wrong.

This assessment considers what the spouse's question reveals about knowledge distribution in bitcoin custody. When someone asks who else knows, they are probing whether the custody arrangement depends entirely on the holder or whether knowledge has been shared in ways that would enable others to act. The holder's attempt to answer exposes what they have communicated, what they believe they have communicated, and the gap between these. Often, the question itself forces recognition that less has been shared than the holder assumed.

Why the Question Arises

Spouses think about what would happen if their partner became unavailable. This concern is not paranoid; it is the ordinary forward-thinking that accompanies shared financial life. Bank accounts have both names on them. Investment accounts have beneficiary designations. The location of important documents is generally known. Bitcoin, often acquired and managed by one spouse without the other's direct involvement, may exist outside this shared knowledge infrastructure. The question "who else knows" emerges from noticing this gap.

Triggering events vary. A news story about lost bitcoin raises the question of whether something similar could happen in this family. A friend's difficult experience with a deceased relative's assets prompts reflection. A health scare makes the topic suddenly urgent rather than theoretical. Whatever the trigger, the spouse is asking a practical question: if you were gone tomorrow, would anyone be able to handle this?

Sometimes the question reflects deeper concerns the spouse may not fully articulate. Is this bitcoin being hidden from me? Is there more than I know about? Are you being secretive because there is something problematic about this? The holder may hear a straightforward logistics question while the spouse is actually probing for transparency about the marriage's financial life. These layered meanings can make the conversation more charged than either party anticipated.

What the Holder Thinks They Know

Asked who else knows, the holder often has an immediate answer: "My brother knows where the backup is." "I told my sister about this." "There's a letter in the safe explaining everything." These answers feel confident because they reference real actions—conversations that occurred, documents that were created. The holder recalls taking steps to share knowledge and concludes that knowledge has been shared.

Confidence in these answers often exceeds their accuracy. The brother knows a backup exists but was never told what to do with it. The sister was told about the bitcoin years ago in a conversation she barely remembers. The letter in the safe assumes knowledge the reader may not possess and has not been updated since circumstances changed. Each confident answer rests on assumptions about what others actually retained, understood, and could act upon—assumptions the holder has not tested.

Memory plays tricks in this domain. The holder may remember intending to tell someone without having actually done so. They may remember a detailed conversation that was actually brief and superficial. They may believe they wrote something down that exists only in their mind. When the spouse's question forces them to think carefully, they may realize their confident answers are based on memories that prove unreliable upon examination.

---

What Others Actually Know

The gap between what the holder believes others know and what others actually know can be vast. A family member who was "told about the bitcoin" may remember only that bitcoin exists and is worth money, without any operational knowledge of where it is or how to access it. A friend who agreed to help in an emergency may have received instructions so long ago that they no longer remember them or no longer have the materials that were shared. The designated helper's actual knowledge may be far less than what the holder's mental model assumes.

Knowledge decays in others just as it decays in the holder. Information shared three years ago has had three years to fade, become confused with other information, or be displaced by more pressing concerns. The person who seemed to understand when the holder explained things may have forgotten almost everything by now. Unless knowledge has been refreshed, tested, or practiced, assuming it persists is assuming more than human memory reliably provides.

Partial knowledge creates its own risks. Someone who knows a little may think they know enough and proceed with confidence in wrong directions. They may attempt recovery using incorrect information, potentially making the situation worse. A person who knows nothing at all might at least seek help; a person who knows a fragment may not realize they need help until their incomplete understanding has led them into an unrecoverable position.

The Spouse's Position

From the spouse's perspective, the answer to "who else knows" determines their own security. If the holder is the only one who truly understands the custody arrangement, then the spouse's access to a potentially significant family asset depends entirely on the holder's continued availability and willingness to explain. This dependency may feel uncomfortable, particularly if the spouse has not chosen it consciously but simply discovered it by asking the question.

Unsatisfying answers create their own concerns. If the holder cannot clearly articulate who knows what, the spouse may conclude that no one really knows anything useful. If the holder names people but cannot explain what those people actually know or how to reach them, the spouse may doubt whether the named people could help in practice. Vague reassurances that "it's all taken care of" without specifics leave the spouse no better informed than before they asked.

The spouse may also evaluate whether they themselves should be among those who know. If the holder's answer is "my friend Steve," the spouse might reasonably wonder why a friend knows more about family assets than they do. This can introduce relationship tensions that complicate the already uncomfortable conversation. The holder may have excluded the spouse from detailed knowledge for legitimate reasons—security concerns, complexity, lack of interest—but the spouse's discovery of this exclusion may not be well received.

What Counts as "Knowing"

The question "who else knows" admits different interpretations, and the holder may answer one interpretation while the spouse means another. Knowing that bitcoin exists differs from knowing how much exists. Knowing where the backup is stored differs from knowing how to use it. Knowing the holder has bitcoin differs from knowing enough to actually recover it. These distinctions matter enormously for practical purposes but may collapse in casual conversation, leading to answers that satisfy the immediate exchange while masking critical gaps.

Operational knowledge—knowing enough to actually perform recovery—is rare outside the holder themselves. Most people who "know about" someone's bitcoin know only that it exists and perhaps roughly what it is worth. They do not know the seed phrase, the passphrase, the derivation path, the wallet software, the storage locations, or the procedures. They know about the bitcoin the way they know about the holder's retirement accounts: awareness without operational capability.

This distinction between awareness and capability often escapes the holder when answering the spouse's question. "My brother knows" sounds reassuring until one asks: knows what, exactly? Knows enough to do what? The holder may believe they have distributed knowledge when they have only distributed awareness, leaving operational knowledge concentrated in themselves alone despite having shared information widely.

Testing the Answer

One way to evaluate the holder's answer is to imagine the spouse actually contacting the named people after the holder's death. Would the brother really know what to do? Could he explain the process, locate the materials, and execute recovery? Would the sister remember the conversation well enough to contribute useful information? Would the letter in the safe actually enable someone unfamiliar with bitcoin to proceed? These thought experiments often reveal that confident answers do not translate into confident outcomes.

Practical tests would be even more revealing. If the holder asked their brother to explain the bitcoin recovery process right now, what would the brother say? If the spouse attempted to follow the letter in the safe without any other help, would they succeed? These tests rarely occur because they feel unnecessary—the holder believes the arrangements work, so why test them?—but their hypothetical results would often demonstrate that the arrangements are less robust than believed.

The spouse asking the question is, in a sense, conducting an informal test. Their dissatisfaction with the answer may reflect accurate intuition that something is missing. They are not asking for theoretical reassurance; they are asking for practical confidence that they could handle this situation if they had to. When the holder's answer fails to provide that confidence, the test has produced a result—just not a written-down one.

What the Question Exposes

The question "who else knows" exposes the holder's custody arrangement to examination in a way that ordinary operation does not. Day-to-day use requires only that the holder can access their own bitcoin. The question asks whether anyone else could access it, and this different standard reveals dependencies and concentrations that normal use conceals. The holder may realize, through trying to answer, that their arrangement is more fragile than they understood.

Knowledge concentration becomes visible. If the honest answer to "who else knows" is "no one," or "no one who could actually do anything," then the bitcoin's accessibility depends entirely on the holder. Every scenario in which the holder becomes unavailable is a scenario in which the bitcoin becomes inaccessible. The holder may have known this abstractly without having confronted it concretely until the spouse's question required them to articulate the situation.

Gaps between intention and implementation also surface. Many holders intend to share knowledge but have not actually done so in effective ways. They plan to write instructions but have not written them. They mean to explain things to family members but have not found the right moment. The spouse's question reveals that intentions have not become actions, and that the custody arrangement exists in its actually-implemented state rather than its intended state.

---

Outcome

When a spouse asks who else knows about bitcoin, the question probes knowledge distribution that the holder may never have examined carefully. Answering requires accounting for who knows what, whether that knowledge remains current, and whether it would actually enable action. Many holders discover through attempting to answer that their confident sense of having shared knowledge does not survive scrutiny—that the people they named know less than assumed, or that no one really knows enough.

The gap between what holders believe they have communicated and what others have actually retained defines much of the vulnerability this question exposes. Conversations fade from memory. Instructions go unread or become outdated. Intentions to share knowledge do not translate into effective sharing. What remains is often a holder who alone possesses operational knowledge, surrounded by people who have awareness without capability.

From the spouse's perspective, an unsatisfying answer raises concerns about access, transparency, and planning. If the holder cannot explain who knows what, the spouse may conclude that no adequate arrangements exist. The question, asked in ordinary concern about what would happen in an emergency, can reveal that the honest answer to that concern is more troubling than either party expected.
