How Do You Subpoena Crypto Exchange Records During a Divorce Case?
Divorce proceedings increasingly involve crypto holdings that one spouse may not have voluntarily disclosed. Getting a full picture of those assets often means going through formal legal channels rather than simply asking.
The short answer
A spouse’s attorney can request account records directly from a known exchange through a subpoena issued as part of the divorce case’s discovery process. If the exchange isn’t identified or doesn’t respond, the court can compel a broader search, and forensic tracing of blockchain activity can help fill in gaps that voluntary disclosure leaves out.
Why crypto records don’t surface automatically
Traditional marital assets like bank accounts and brokerage holdings usually appear on statements, tax forms, or credit reports, which makes them relatively easy to locate during discovery. Crypto holdings often leave a much thinner paper trail. An account with an exchange doesn’t generate the same kind of routine mail or third-party reporting that a checking account does, and self-custodied holdings in a private wallet may leave no institutional record at all. This is one reason cryptocurrency has become a recurring issue in divorce litigation — it’s the kind of asset that can be underreported not through sophisticated concealment but simply because no one asks the right question.
The steps involved in subpoenaing exchange records
- Identify the exchange. Bank statements, credit card charges, emails, or tax documents can reveal which platform a spouse used, even if the account itself was never mentioned.
- Draft and serve the subpoena. An attorney prepares a formal request specifying the account, the time period, and the type of records sought — transaction history, deposits, withdrawals, and balances.
- Send it to the exchange’s registered agent for service. Most exchanges have a designated process for receiving legal requests, often through a dedicated legal or compliance department.
- Allow for a response window. Exchanges typically have a set period to comply, object, or seek clarification, similar to how a bank would respond to a subpoena for account records.
- Escalate to the court if needed. If a spouse or the exchange resists, the requesting party’s attorney can ask the court to compel compliance.
What happens if the exchange isn’t known
When there’s no clear indication of which platform was used, discovery can rely on other tools: written interrogatories asking the other spouse to disclose all crypto holdings under oath, forensic review of bank transfers that suggest a crypto purchase, or a subpoena to an internet service provider for account activity tied to known crypto-related IP traffic. A forensic accountant familiar with tracking a transaction on a blockchain explorer can sometimes trace funds even without exchange cooperation, since blockchain activity is often publicly visible even when the identity behind an address is not.
Why self-custody complicates things further
If a spouse holds crypto in a private wallet rather than on an exchange, there is no institution to subpoena at all. The only records are whatever exists on the blockchain itself, plus any digital trail — device backups, seed phrase notes, or wallet software — that a forensic examiner can uncover during the discovery process. This is part of why understanding what a private key actually controls matters in these cases: whoever holds the key has practical control over the asset, regardless of what a court later orders regarding its division.
What courts can and cannot do
A court can order a spouse to disclose holdings, compel testimony, and impose sanctions for concealment discovered later, including adjusting the division of other assets to account for hidden crypto. What a court generally cannot do is force disclosure of information that genuinely doesn’t exist in any accessible record, which is why proactive discovery — subpoenas, forensic tracing, and sworn disclosures — matters more with crypto than with assets that already show up on a 1099 or a bank statement. This is closely related to how an executor proves ownership of cryptocurrency without physical certificates in a probate setting, since both situations require establishing control over an asset that leaves no conventional paper trail.
The takeaway
Crypto assets are treated the same as any other marital property in the eyes of most courts, but locating and verifying them takes more legwork because the usual paper trail often doesn’t exist. Subpoenaing exchange records is a standard discovery tool, and when an exchange can’t be identified, forensic tracing and court-compelled disclosure are the fallback options attorneys use to make sure a full accounting includes digital assets alongside everything else.
