The account balances look lower than they should. The brokerage statements don’t add up to the lifestyle you’ve shared for years. Your spouse handles the finances, knows the passwords, and lately has been spending more time on apps you don’t recognize. If that description sounds familiar, you may be dealing with something increasingly common in high-net-worth New York City divorces: a spouse who has quietly moved marital assets into cryptocurrency.
At Eiges & Orgel at Ballon Stoll P.C., we’ve handled over 3,000 divorce cases, and we’ve watched digital assets grow from a footnote into a genuine battleground in complex matrimonial proceedings. What follows is a detailed look at how hidden cryptocurrency works, what New York law actually requires, and how the discovery process can surface assets a spouse thought were invisible.
Why Cryptocurrency Complicates High-Net-Worth Divorces in New York
Traditional financial discovery works because banks, brokerages, and retirement account custodians all keep records and respond to subpoenas. Cryptocurrency held in private wallets doesn’t play by those rules. A spouse can hold hundreds of thousands of dollars in Bitcoin or Ethereum on a hardware wallet the size of a USB drive, and no institution will ever generate a statement about it.
The distinction between wallet types matters here. Centralized exchanges like Coinbase, Gemini, and Kraken function somewhat like traditional brokerages: they maintain account records, verify user identities, and respond to legal process. A hardware wallet like a Ledger or Trezor device (sometimes called cold storage) stores cryptocurrency entirely offline. There’s no company to subpoena and no monthly statement to request. The only record that exists is on the blockchain itself.
That information gap is sharpest when one spouse manages household finances and has a stronger technical background. Someone who already controls investment accounts and understands how crypto works has a real advantage when it comes to quietly converting marital funds into digital assets the other spouse doesn’t know to look for.
Is Cryptocurrency Marital Property Under New York Law?
New York courts treat cryptocurrency as property subject to equitable distribution under Domestic Relations Law § 236(B), the same statute governing bank accounts, retirement funds, and real estate. Under § 236(B)(1)(c), marital property includes virtually all property acquired by either spouse during the marriage, regardless of the form in which title is held. That phrase “regardless of the form in which title is held” is doing real legal work: the asset category doesn’t matter. A Bitcoin wallet, a staking position in Ethereum, or a collection of NFTs purchased during the marriage with marital income all fall within the definition.
New York is an equitable distribution state, which means marital property isn’t automatically divided 50/50. Courts divide it fairly based on factors including the length of the marriage, each spouse’s contribution to the marital estate, and each party’s financial circumstances going forward. If one spouse brought cryptocurrency into the marriage as a separate asset, tracing its origin and any appreciation attributable to marital effort becomes essential. If it was acquired after the wedding, it’s presumptively marital property.
How Forensic Investigators Uncover Hidden Crypto in Discovery
Hiding cryptocurrency is harder than it looks. A New York case covered by CNBC illustrates how difficult concealment can be in practice: one spouse spent six months in discovery, brought in a forensic accountant, and eventually tracked down 12 bitcoins held in a previously undisclosed wallet, then worth roughly half a million dollars. That case demonstrates both the scope of what’s at stake and the tools that actually work.
The discovery toolkit in a New York matrimonial case includes several concrete mechanisms:
- Exchange subpoenas: Subpoenas directed at Coinbase, Gemini, Kraken, and similar centralized platforms can produce full account histories, including deposits, withdrawals, and transfers to external wallets.
- Blockchain analysis: Because every transaction on a public blockchain is permanently recorded, forensic analysts can follow funds even after they move from an exchange into a private wallet or cold storage device. The trail doesn’t disappear; it just requires someone who knows how to read it.
- Financial statement inconsistencies: Unexplained wire transfers to exchange accounts, hardware wallet purchases on credit card statements, and discrepancies between reported income and actual spending patterns all serve as warning signs.
- Tax return disclosures: The IRS requires every taxpayer to answer a digital asset question on Form 1040. Beginning with the 2025 tax year, custodial brokers are also required to report digital asset proceeds to the IRS on Form 1099-DA, giving the agency independent data to cross-reference against filed returns. A “yes” answer on a prior return, or a suspicious omission where earlier years showed crypto activity, can be powerful evidence.
DeFi positions and staking rewards add another layer of complexity. Unlike a wallet that simply holds Bitcoin, a spouse might have funds locked in decentralized finance protocols earning yield or collecting staking rewards from a proof-of-stake network. These positions don’t show up in any traditional account. A forensic accountant familiar with blockchain infrastructure is often the right person to identify and quantify what’s actually there.
Valuing Cryptocurrency for Equitable Distribution
Even once an asset is found, its value still has to be determined. Cryptocurrency markets don’t hold still. Bitcoin, for example, has moved more than 20 percent in a single week on multiple occasions. That volatility turns the valuation date question into a serious negotiating issue, one with real dollars attached to it.
New York courts don’t apply a single fixed valuation date to all marital assets. The choice between the date of filing, the date of separation, or the date of trial can change the value of a crypto holding by an enormous margin. Courts generally treat crypto as a passive asset, meaning its appreciation or depreciation doesn’t depend on either spouse’s active effort after the marriage ends. That framing tends to push the valuation date toward the trial date rather than the filing date, but the issue is genuinely contested and turns on the specific facts of each case.
NFT valuation presents its own challenges. Unlike fungible tokens, a non-fungible token has no liquid market equivalent. Establishing fair market value often requires a combination of comparable sales data, platform transaction history, and sometimes an independent appraiser with experience in digital assets. Dismissing NFT holdings because they seem speculative or minor is a mistake. Some collections have traded at values that would be significant in any equitable distribution analysis.
What New York Law Actually Requires You to Disclose
Some recent posts have claimed that a revised Statement of Net Worth now contains a dedicated cryptocurrency disclosure section. That claim isn’t supported by the official New York Courts record of matrimonial form revisions. The changes effective March 1, 2026 address Child Support Standards Act income caps and the Self Support Reserve. There’s no documented addition of a crypto-specific line item in those revisions.
That doesn’t mean cryptocurrency gets a pass. The Statement of Net Worth required under Domestic Relations Law § 236(B)(4) and 22 NYCRR 202.16 already requires both spouses to disclose all assets under oath. Cryptocurrency is an asset. Omitting a wallet holding $50,000 in Ethereum because there’s no dedicated line item for it is still a failure to disclose a marital asset under an instrument signed under penalty of perjury.
The practical consequence is CPLR 3126 sanctions. Under that rule, a court can strike pleadings, draw adverse inferences, or award attorney fees when a party willfully fails to comply with disclosure obligations. Courts have applied these sanctions in cases involving concealed crypto. A spouse who assumes an undisclosed wallet is legally invisible is taking a serious risk.
What to Do If You Suspect Hidden Digital Assets
Suspicion alone doesn’t move a case forward. What moves it forward is early, thorough discovery, before assets are transferred further into cold storage, sold, or moved across exchanges in jurisdictions that don’t respond to subpoenas. Gather whatever financial documents you currently have access to, note any unusual transfers or hardware purchases, and check whether your spouse has filed tax returns disclosing digital assets in prior years. These details give our attorneys and a forensic accountant a starting point that would otherwise take months to reconstruct.
The valuation question also cuts both ways. If you own cryptocurrency and are concerned about how it will be treated in your divorce, understanding the valuation date framework matters just as much. A sharp drop in value between filing and trial affects what you may owe or receive, and the argument for which date applies isn’t always obvious.
The legal tools to compel disclosure, trace blockchain transactions, subpoena exchange records, and sanction a spouse who hides assets already exist under New York law. The question is whether they’re deployed early and effectively enough to matter.
