When a family-law attorney suspects a spouse is hiding cryptocurrency, the instinct is to go straight to the chain. Find the wallet, follow the coins, prove the asset. It feels like the technical heart of the problem.
It is also the wrong place to start, and starting there is how hidden crypto stays hidden.
The asset class with no one to subpoena
Financial discovery is built around institutions. You subpoena the bank, the brokerage, the employer, the title company. Each one is a custodian holding records and assets on someone else's behalf, and each one answers to a court order.
Self-custodied crypto breaks that model. A spouse holding Bitcoin on a hardware wallet, or a seed phrase written on a card in a drawer, has no custodian. There is no institution to serve, no statement to compel, no account to freeze. The standard discovery playbook sweeps right past it, because the playbook assumes a third party is holding the asset, and that is not the case here.
That is the gap. The more sophisticated the spouse, the better they understand that the assets are effectively invisible to the usual process.
Start with the fiat trail, not the chain
This is the part that surprises most people. The strongest first evidence of hidden crypto usually is not on the blockchain at all. It is in the records you may already have access to.
Dollars have to become crypto somewhere. With rare exceptions, that means a regulated on-ramp through a centralized exchange like Coinbase, Kraken, or Gemini, or a payment processor like PayPal, Square, or Cash App, and that means a bank transfer, a card charge, or a wire that can be reached through records discovery. You may find crypto purchases made via one of these platforms two years ago, but in the financial affidavit there are no corresponding holdings matching those purchases. You have a documented gap between money that went in and assets that came back out.
That gap is the thread you pull. You look at bank statements, credit reports, tax filings, and the exchange's own response to a properly directed subpoena, and that is where the on-chain trail begins. Where did the assets go after they left the exchange?
What "found" actually means
Two distinctions matter once an asset surfaces, and getting them wrong can make a case go sideways.
An address is not control. Identifying a wallet that holds the crypto is not the same as proving who controls it, and it is also not the same as recovering it. Those are three separate things.
Valuation is its own problem. The value of crypto swings, and the date you choose matters. Are you looking for the value at the date of separation, the date of filing, or the date of trial? These numbers can change drastically. For equitable distribution, the valuation has to be defensible, documented, and consistent, not a screenshot of today's price.
The goal is not a dramatic recovery. It is a clear, defensible answer to two questions. Does the asset exist, and what is it worth? That answer holds up because it is built on records and methodology, not on guesswork.
Where this fits
Secure Data Consortium helps family-law attorneys identify and value cryptocurrency in marital estates. Establishing what is there, valuing it on a defensible basis, and tracing its movement where the facts support it. The deliverable is a written analysis you can use in negotiation or put in front of a court, with its methodology and its limits stated plainly.
If a case looks like it has undisclosed crypto and standard discovery is not reaching it, that is the work we do. The earlier we talk, the better. Assets move, get layered across wallets, and once a settlement is signed, the window to act on them is mostly closed. Send the affidavit and whatever is raising the suspicion, and with a short scoping call we can tell you whether there is a real asset to pursue and what documenting it would take. We keep our caseload deliberately small, so reaching out early is the surest way to get a matter looked at.
