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. 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 useful for anyone navigating a divorce where digital assets are a concern.
This article explains the subpoena process for cryptocurrency exchanges in plain English. It is educational only and does not constitute legal advice. For guidance specific to your situation, please consult a qualified family law attorney.
Key Takeaways
- Regulated cryptocurrency exchanges are generally required to maintain customer records and comply with valid subpoenas issued through US legal proceedings.
- Exchange subpoenas can produce account details, transaction histories, deposit and withdrawal records, and identity verification information.
- The subpoena process for cryptocurrency 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 investigative 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 directly. 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. For a full overview of how the discovery process works see our guide to how divorce discovery works.
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-facing exchanges may include Coinbase, Gemini, Kraken, Binance.US, and Crypto.com, among others.
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 generally required to comply with valid subpoenas issued in connection with US legal proceedings.
Foreign exchanges operating outside US jurisdiction present more challenges. While some may 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 a range of records including account registration information such as name, address, date of birth, and government ID used for verification. Transaction histories covering all buy, sell, send, and receive activity on the account are usually available, along with deposit and withdrawal records showing the bank accounts used to fund the exchange account. Current and historical account balances, linked wallet addresses, login and activity records, and tax reporting documents such as 1099 forms issued by the exchange may also be obtainable.
A complete exchange record can provide a detailed picture of a spouse’s cryptocurrency activity covering an extended period. For more on what tax records can reveal about cryptocurrency activity see our guide to cryptocurrency tax records in divorce.
How the Subpoena Process Works
- 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 cannot be obtained through an exchange subpoena. Other methods, such as blockchain analysis and bank statement review, may be needed to identify hardware wallet activity.
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.
Closed Accounts
If a spouse has closed an exchange account, the exchange may still hold historical records — but retention policies vary by platform. 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 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
- Email records — exchange registration confirmation emails, transaction notifications, and verification emails may be present on 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 approach. Other methods that may be used include blockchain analysis — tracing wallet addresses on public ledgers once they have been identified — Bitcoin ATM records, tax record review including the cryptocurrency disclosure question on Form 1040 and capital gains schedules, and forensic accounting.

Frequently Asked Questions
Can I subpoena a crypto exchange myself?
No. Subpoenas must be issued through the formal legal process by an attorney. 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 may 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 for longer periods. The specific retention period varies by exchange. Acting promptly through the discovery process gives the best opportunity to obtain complete records.
What if my spouse used a decentralised exchange?
Decentralised exchanges 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, like other regulated exchanges, generally has procedures in place for responding to valid legal process requests.
What if my spouse used a foreign exchange?
Foreign exchanges are not automatically subject to US subpoena power. Some may cooperate voluntarily; others may not. Your attorney can advise on the options available, which may include mutual legal assistance requests or other approaches depending on the jurisdiction involved.
Does a subpoena guarantee I will find hidden cryptocurrency?
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 generally gives the most complete picture.
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 more effective tools available when digital assets are a concern in divorce proceedings. Major US exchanges are regulated, maintain detailed records, and are generally required to comply with valid subpoenas. The records they produce can provide a detailed picture of a spouse’s cryptocurrency activity over an extended period.
Exchange subpoenas work best as part of a broader discovery approach — combined with bank statement review, tax record analysis, and where appropriate, forensic accounting expertise. If cryptocurrency is a concern in your divorce, raising it with your attorney early and addressing it comprehensively in the discovery process is the most effective approach.
