Subpoenaing Coinbase, Gemini & Other Cryptocurrency Exchanges in a New York Divorce
Cryptocurrency exchange accounts such as Coinbase and Gemini are discoverable in a New York divorce. Courts may compel production of identity records, transaction histories, wallet transfers, and related financial documentation. These records are frequently the starting point for tracing high-net-worth digital assets under New York’s equitable distribution law.
Now let’s talk about what that really means when serious money is involved.
A Brief Primer (If You Need It)
For those of you who live in this world — who trade, stake, hold cold wallets, and argue about layer-2 scaling over dinner — you can skip ahead.
For everyone else, let’s level-set. Before we can address Subpoenaing Cryptocurrency Exchanges, we need to understand what they are.
Cryptocurrency is not “money” in the traditional sense. It is software recorded on a distributed ledger known as a blockchain. (For our purpose here, we really don’t need to dive too deep into this quagmire. But, for those interested here’s an article on what “blockchain” is.)
Suffice to day that this ledger is public. Every transaction is permanently recorded. Once entered, it cannot be altered or erased.
Think of it this way: imagine a global spreadsheet that everyone can see but no one can secretly edit. Each entry is time-stamped, verified by a network of computers, and permanently stored.
That is the blockchain.
Ownership is controlled through something called a private key — essentially a cryptographic password. If you control the private key, you control the asset. If you lose it, the asset may be unrecoverable. This is actually the premise of an episode of the “Big Bang Theory.”
There are generally two ways people hold digital assets:
- On a centralized exchange like Coinbase or Gemini.
This is similar to holding stock in a brokerage account. The exchange maintains custody and keeps records. - In self-custody wallets (hardware wallets, software wallets, multi-signature wallets).
Here, the individual controls the private key directly. There is no institution in the middle.
Beyond basic cryptocurrency like Bitcoin or Ethereum, the digital asset world includes:
- Stablecoins (digital tokens pegged to the U.S. dollar)
- NFTs (unique digital assets)
- Tokenized equity
- DAO governance tokens
- Blockchain-based compensation
- Liquidity pool positions
- Staking rewards
Some function like speculative commodities. Others function more like securities. Regulators are still refining classifications.
Divorce courts, however, do not wait for regulatory clarity.
If it was acquired during the marriage, it is potentially marital property.
That’s the legal lens.
Now let’s talk about how that plays out when significant wealth is involved.
The First Question Is Not “What Is It Worth?” It’s “Where Is It?”
In high-net-worth divorces involving digital assets, the most important early move is not valuation. It’s location.
Cryptocurrency does not sit in a vault. It sits in an ecosystem. That ecosystem often begins with a centralized exchange, as discussed upon, — Coinbase, Gemini, Kraken, Binance — where digital assets are bought, sold, converted, and transferred.
And here is something sophisticated investors understand but many people still don’t:
These exchanges are not anonymous playgrounds. They are compliance-driven financial institutions.
I know that the internet claims that you can hide all your assets. Yes, maybe and to a point.
But, they do collect identifying information. They link to bank accounts. They generate transaction records. They track deposits and withdrawals. They maintain internal logs.
From a litigation standpoint, that makes them data repositories.
In the 21st century, it has become increasingly harder to hide money and transactions. This is not like my father’s day (a famous Mob Lawyer) when pizzeria’s, dry cleaners and even a famous sex club were used to launder cash.
Now, everything leaves a digital footprint.
If you understand how New York’s equitable distribution statute operates — and I explain that more fully here

— you understand why that data matters. If the asset was acquired during the marriage, it is presumptively marital property, regardless of whose name appears on the exchange account.
Title does not control. Timing and source of funds do.
What a Subpoena Actually Reveals
When properly drafted and served, a subpoena to a centralized exchange can produce far more than a simple balance statement. Sure, in the divorce process we can issue demands to your spouse. In my experience, people tend not to fully answer or respond to these demands. That’s why I like subpoenas. I can get the information directly from the third party, and since they have no dog in the fight, are all too willing to answer the subpoena.
A subpoena can produce:
- Account creation documents
- Identity verification materials
- Linked financial institutions
- Complete trading history
- Conversion activity
- Stablecoin movements
- Staking rewards
- Withdrawal destinations
- Device access logs
In sophisticated cases, those records are not merely informative — they are transformative.
They often reveal patterns of behavior:
Large purchases before marital strain.
Conversions immediately before filing.
Transfers to external wallets after counsel was retained.
Sudden migration to international platforms.
Cryptocurrency may be modern. Concealment strategy is not. I address that broader pattern here:

The technology evolves. Human behavior rarely does.
When the Assets Leave the Exchange
A frequent tactic in high-net-worth cases is to move digital assets off a centralized exchange into self-custody wallets.
That move is meant to create distance.
It does not erase history.
Blockchain transactions are permanent and publicly recorded. Once funds leave Coinbase, the withdrawal address is visible. From there, blockchain analysis can follow wallet-to-wallet transfers across networks.

The practical takeaway for divorce litigation is straightforward:
Digital assets leave a trail.
The legal challenge is not visibility. It is attribution — linking the wallet to the individual.
Exchange records are frequently the bridge that makes that link possible.
Timing and the Automatic Orders
In New York, once a divorce action is filed, automatic orders go into effect. These orders prohibit the transfer or concealment of marital assets.
That includes cryptocurrency.
But if substantial transfers occur before filing — or if digital assets move rapidly in anticipation of litigation — the analysis shifts from preservation to reconstruction.
That reconstruction can involve:
- Bank transfer analysis
- Exchange subpoenas
- Wallet mapping
- Cross-platform tracing
- Device-level forensic review
The earlier digital assets are identified, the more controlled the litigation becomes.
In high-net-worth cases, control is everything.
Stablecoins and Sophisticated Conversion Strategies
When markets become volatile, sophisticated holders often convert into stablecoins — digital tokens designed to maintain a fixed value.
Under recently enacted federal legislation, certain stablecoin issuers must maintain 1:1 backing with U.S. dollar reserves. That regulatory framework reduces volatility but does not eliminate discoverability.
From a divorce strategy perspective, stablecoins are frequently used to:
- Lock in gains
- Reduce exposure
- Mask the movement of funds
- Park liquidity pending transfer
But the exchange records capture the transition.
A conversion from Bitcoin to a dollar-pegged stablecoin does not make the asset disappear. It simply changes its profile.
Offshore Exchanges and Jurisdictional Complexity
High-net-worth individuals sometimes hold digital assets on offshore exchanges.
This does not mean the assets are beyond reach.
A New York court has jurisdiction over the parties. It can compel disclosure. It can order production of records within a party’s control.
The complication lies in enforcement against foreign entities.
That may involve:
- Treaty analysis
- Regulatory cooperation frameworks
- Targeted court orders
- Strategic litigation pressure
In cross-border digital asset cases, jurisdiction is not a footnote. It is a primary consideration.
When a Blockchain Forensic Expert Is Essential
Not every digital asset divorce requires an outside forensic specialist.
But in cases involving substantial value, layered wallets, rapid transfers, or international custody, expert involvement becomes prudent.
Courts may appoint a neutral expert. Costs may be allocated between the parties. The expense is real.
But so is the cost of failing to trace significant digital wealth.
High-net-worth litigation is rarely about whether you can afford expertise.
It is about whether you can afford not to use it.
Strategic Perspective
Subpoenaing Coinbase is not about spectacle.
It is about discipline.
A structured approach to digital asset discovery typically involves:
- Bank statement review
- Tax return analysis
- Exchange subpoenas
- Identification of outbound wallet addresses
- Blockchain tracing if warranted
In many cases, traditional financial discovery reveals the existence of digital assets before blockchain analysis is even required.
The blockchain then confirms the movement.
The key is knowing where to begin.
Frequently Asked Questions
Can Coinbase records be subpoenaed in a New York divorce?
Yes, subpoenaing Cryptocurrency Exchanges is done all the time. Centralized cryptocurrency exchanges maintain identity verification and transaction records. These records are discoverable through subpoena and court order.
If the crypto account is only in my spouse’s name, is it still marital property?
If the asset was acquired during the marriage, it is generally marital property under New York equitable distribution law, regardless of title.
What if the crypto was moved to a private wallet?
Exchange records will identify the withdrawal address. This is why Subpoenaing Cryptocurrency Exchanges is critical. Blockchain analysis can trace subsequent transfers. The legal issue becomes attribution and proof of control.
Can the court freeze cryptocurrency accounts?
Yes. Courts may issue restraining orders prohibiting transfer of marital assets, including digital assets held on centralized exchanges.
Final Thought
Digital assets do not intimidate the law.
They complicate the facts.
High-net-worth divorce involving cryptocurrency requires more than general family law knowledge. It requires understanding how exchanges operate, how blockchain records function, how regulatory frameworks affect custody, and how to structure discovery before assets move beyond easy reach.
If digital assets are part of your financial landscape, your legal strategy should reflect that reality from the outset.
