Introduction
When cryptocurrency is suspected in a divorce and voluntary disclosure has not been forthcoming, one of the most effective legal tools available is a subpoena to a cryptocurrency exchange. Just like a bank subpoena, this legal order compels the exchange to produce account records, transaction histories, and identity information directly — bypassing the other spouse entirely.
Understanding how this process works, which exchanges are subject to it, and what information it can produce is important for anyone navigating a divorce where digital assets are a concern.
This guide explains the subpoena process for cryptocurrency exchanges in plain English. As always, nothing here constitutes legal advice — consult a qualified family law attorney for guidance specific to your situation.
Key Takeaways
- Regulated cryptocurrency exchanges are legally required to maintain customer records and comply with valid subpoenas.
- Exchange subpoenas can produce account details, transaction histories, deposit and withdrawal records, and identity verification information.
- The subpoena process for crypto exchanges is broadly similar to subpoenaing a bank.
- Not all cryptocurrency activity goes through regulated exchanges — peer-to-peer transactions and hardware wallets require different approaches.
- Your attorney manages the subpoena process — your role is to provide information about which exchanges your spouse may have used.
Important Note: Subpoenas can only be issued through the formal legal process. You cannot subpoena an exchange yourself. This must be done through your attorney as part of the discovery process in your divorce proceedings.

What Is a Subpoena?
A subpoena is a legal order issued by a court or an attorney acting within the discovery process. It compels the recipient — a person or an organisation — to produce documents, records, or testimony.
In divorce proceedings, subpoenas are commonly used to obtain financial records directly from third parties such as banks, employers, and financial institutions. The same mechanism applies to cryptocurrency exchanges — and the results can be just as revealing.
Which Exchanges Can Be Subpoenaed?
Cryptocurrency exchanges that operate as regulated businesses in the United States are subject to subpoena in the same way as any other financial institution. Major US-regulated exchanges include:
- Coinbase
- Gemini
- Kraken
- Binance.US
- Crypto.com
These exchanges are registered with FinCEN as Money Services Businesses and are required to maintain Know Your Customer (KYC) records — meaning they hold verified identity information for their customers. They are legally required to comply with valid subpoenas issued in connection with US legal proceedings.
Foreign exchanges operating outside US jurisdiction present more challenges. While some foreign exchanges will cooperate with US legal process, others may not. Your attorney can advise on the options available depending on which exchanges are involved.
What Records Can a Subpoena Produce?
A subpoena to a cryptocurrency exchange can typically produce:
- Account registration information — name, address, date of birth, government ID used for verification
- Transaction history — complete record of all buy, sell, send, and receive transactions on the account
- Deposit and withdrawal records — including the bank accounts used to fund the exchange account
- Current and historical account balances
- Linked wallet addresses — which can then be traced on public blockchains
- Login and activity records — IP addresses, device information, and access logs
- Tax reporting records — 1099 forms and other tax documents issued by the exchange
This is a substantial amount of information. A complete exchange record can provide a detailed picture of a spouse’s cryptocurrency activity going back years.
How the Subpoena Process Works
The process of subpoenaing a cryptocurrency exchange follows the same general steps as subpoenaing any financial institution:
- Your attorney identifies the relevant exchanges based on information you provide, bank statement review, or other evidence.
- A subpoena is drafted specifying the records requested and the time period covered.
- The subpoena is served on the exchange through the appropriate legal mechanism.
- The exchange reviews the subpoena and produces the requested records, typically within a specified timeframe.
- The records are reviewed by your attorney and, if relevant, by a forensic accountant.
The timeline varies depending on the exchange and the complexity of the request. Some exchanges have dedicated legal compliance teams and respond promptly. Others may take longer or request clarification.
Limitations of Exchange Subpoenas
Not All Crypto Goes Through Exchanges
Cryptocurrency can be purchased peer-to-peer, through Bitcoin ATMs, or via decentralised exchanges that do not hold customer identity records. Activity that bypasses regulated exchanges may not be captured by a standard exchange subpoena.
Hardware Wallets Leave No Exchange Record
Cryptocurrency stored in a hardware wallet — a physical device held offline — is not held by any exchange and therefore cannot be obtained through an exchange subpoena. Other methods, such as blockchain analysis and bank statement review, are needed to identify hardware wallet activity (read our in-depth guide on Crypto Wallets in Divorce Cases).
Foreign Exchanges May Not Comply
Exchanges based outside the United States are not automatically subject to US subpoena power. While some foreign exchanges will cooperate voluntarily, others may not. This is an area where the advice of an attorney with international experience may be valuable.
Deleted Accounts
If a spouse has closed an exchange account, the exchange may still hold historical records — but retention policies vary. Acting promptly through the discovery process is important to maximise the records available.
How to Identify Which Exchanges to Subpoena
To issue an effective subpoena, your attorney needs to know — or have reason to believe — that a particular exchange was used. Useful sources of this information include:
- Bank and credit card statements — payments to cryptocurrency exchanges often appear as identifiable transactions. Common exchange names appear as merchant descriptions.
- Email records — exchange registration confirmation emails, transaction notifications, and KYC verification emails may be present on shared or accessible email accounts.
- Tax returns — 1099 forms from exchanges may be attached to or referenced in tax filings.
- Interrogatory responses — your attorney can ask directly which exchanges your spouse has used as part of the written discovery process.
- Device records — exchange apps on a shared device may indicate which platforms were used.
Beyond Exchanges — Other Crypto Discovery Tools
Exchange subpoenas are one tool in a broader cryptocurrency discovery toolkit. Other approaches include:
- Blockchain analysis — once a wallet address is identified, a forensic professional can trace its complete transaction history on the public blockchain (learn more about Can a Spouse Hide Bitcoin During Divorce?)
- Bitcoin ATM records — Bitcoin ATM operators are required to maintain records of transactions above certain thresholds
- Tax record review — IRS Form 1040 now includes a cryptocurrency disclosure question; capital gains from crypto appear on Schedule D
- Forensic accounting — a forensic accountant with cryptocurrency expertise can analyse financial records holistically to identify digital asset activity (see our pricing breakdown on Forensic Accountant Divorce Cost)

Frequently Asked Questions
Can I subpoena a crypto exchange myself?
No. Subpoenas must be issued through the formal legal process by an attorney. You cannot subpoena an exchange on your own. Raise your concerns with your attorney and ask about the discovery options available to you.
Will the exchange tell my spouse that a subpoena was issued?
In many cases, exchanges are required to notify the account holder that a subpoena has been received unless a court order prohibits notification. Your attorney can advise on whether a non-disclosure order is appropriate in your case.
How far back do exchange records go?
Most regulated exchanges retain records for several years, and some maintain records indefinitely. The specific retention period varies by exchange. Acting promptly through the discovery process gives you the best chance of obtaining complete records.
What if my spouse used a decentralised exchange?
Decentralised exchanges (DEXs) do not hold customer identity records in the same way as centralised exchanges. However, transactions on decentralised exchanges are recorded on public blockchains and can be traced by forensic professionals. Your attorney and forensic accountant can advise on the options available.
Can Coinbase be subpoenaed?
Yes. Coinbase and other major US-regulated exchanges are subject to subpoena as part of legal proceedings. Coinbase has a dedicated legal process compliance team and responds to valid subpoenas issued in connection with US court proceedings.
What if my spouse used a foreign exchange?
Foreign exchanges are not automatically subject to US subpoena power. Some will cooperate voluntarily; others may not. Your attorney can advise on the options available, which may include mutual legal assistance requests or other international legal mechanisms.
Does a subpoena guarantee I will find hidden crypto?
Not necessarily. A subpoena produces records from the specific exchange subpoenaed. If cryptocurrency was held elsewhere — on a foreign exchange, in a hardware wallet, or through peer-to-peer transactions — those records will not be captured. A comprehensive approach combining multiple discovery tools gives the best results.
How much does it cost to subpoena a crypto exchange?
The cost depends on your attorney’s fees for drafting and serving the subpoena, any fees charged by the exchange for producing records, and the complexity of reviewing the records produced. Your attorney can give you an estimate based on your specific circumstances.
Final Thoughts
Subpoenaing cryptocurrency exchange records is one of the most effective tools available when digital assets are a concern in divorce proceedings. Major US exchanges are regulated, maintain detailed records, and are legally required to comply with valid subpoenas. The records they produce can provide a comprehensive picture of a spouse’s cryptocurrency activity.
Exchange subpoenas work best as part of a broader discovery strategy — combined with bank statement review, tax record analysis, and where appropriate, forensic accounting expertise. If cryptocurrency is a concern in your divorce, raise it with your attorney early and make sure it is addressed comprehensively in your discovery plan.
