When one spouse holds cryptocurrency, blockchain tracing can help counsel test financial disclosures, follow transfers made during the marriage, and identify where records can be sought through discovery.
Why crypto is hard to find in a divorce
Cryptocurrency does not sit in a single account with a monthly statement mailed to the family home. It can be held on an exchange, in a mobile wallet app, on a hardware device in a drawer, or across dozens of addresses that carry no names. A spouse who was not involved may know only that "there was some Bitcoin."
For US tax purposes, the IRS treats digital assets as property, not currency. In family court, the questions are usually about characterization, value and completeness: was the crypto acquired during the marriage, was it bought with separate funds, and has everything been disclosed? In Fial and Fial (Or. Ct. App. 2026), the division of cryptocurrency bought during the marriage turned substantially on evidence tracing the purchases to one spouse's premarital retirement accounts. Tracing evidence can matter to either side.
Patterns that commonly call for a closer look include:
- Transfers from a disclosed exchange account to wallets that do not appear on the financial affidavit
- Withdrawals shortly before or after separation, or a sudden drop in a disclosed balance
- Assets moved to an account in a relative's or business's name
- Conversion into less common tokens, or into stablecoins that hold a steady dollar value
What tracing can show about a spouse’s crypto
Public blockchains record every transfer permanently. Starting from a known address or exchange withdrawal, a trace can often show:
- Holdings: balances at known addresses on a given date, such as the date of separation or filing
- Transfers: where funds went, when, and in what amounts
- Exchange touchpoints: deposits into identifiable exchanges or other service providers, where account records can be sought through legal process
- Timelines: a dated sequence of movements to set against disclosures and testimony
- Commingling: where separate and marital funds may have flowed through the same wallets
What tracing can’t do in a divorce
A blockchain address has no name attached. Tracing can show that funds reached an exchange; tying an account to a person usually needs the exchange's own records, obtained through subpoena or court order. Privacy coins, mixers and some cross-chain swaps can limit or break a trace, and funds held in a wallet no one has identified cannot be found from the blockchain alone. Tracing establishes movements; valuation dates and property characterization remain questions for counsel and the court.
Evidence that helps find hidden crypto
- Exchange statements, transaction histories and account confirmation emails
- Tax returns, including the digital asset question on Form 1040, and any Form 1099-DA. US custodial brokers must report gross proceeds on Form 1099-DA for sales made on or after January 1, 2025, with basis reporting for certain sales from 2026
- Bank and card statements showing transfers to or from exchanges
- Known wallet addresses, screenshots, or wallet apps seen on a phone or computer
- Names of exchanges, apps or hardware wallets that were mentioned or used
Note that a Form 1099-DA only comes from custodial platforms. Activity in self-custody wallets generally will not appear on one. We cannot advise on how evidence may lawfully be obtained from a spouse's devices or accounts; that is a question for your attorney.
How ChainWatch works with counsel
Most matters begin with a case review, where we review what you have and tell you plainly whether tracing is likely to be useful. Where it is, we scope an investigation with a quote before any work begins. Findings are delivered in a written report a non-specialist can follow. For matters headed to hearing, litigation support is available on a retainer or hourly basis, including expert reports and declarations.
We can also act under a neutral follow-the-asset mandate, jointly instructed or court-appointed, reporting what the blockchain shows without advocating for either spouse. All engagements are handled confidentially.
Crypto in divorce: common questions
Am I entitled to half of my spouse’s crypto?
That depends on your state’s law and on whether the crypto is marital or separate property, which are questions for your family-law attorney. Tracing can supply the facts those questions turn on: when the crypto was acquired and what money paid for it. In Fial and Fial (Or. Ct. App. 2026), the division of crypto bought during the marriage turned substantially on evidence tracing the purchases to one spouse’s premarital retirement accounts.
How can I tell if my spouse is hiding crypto?
Common signs are transfers from a disclosed exchange account to wallets that aren’t on the financial affidavit, withdrawals around the time of separation, a sudden drop in a disclosed balance, and assets moved into a relative’s or business’s name. Tax records can help too: the digital asset question on Form 1040, and Form 1099-DA from US custodial platforms for sales from 2025.
Can I work with you directly, or must it go through my attorney?
Spouses can contact us directly for an assessment. If the findings may be used in court, we strongly recommend involving your family-law attorney early so the work fits the case.
Will you tell me who owns a wallet?
Not from the blockchain alone. We can show where funds moved and which exchanges they reached. Account-holder identity comes from records those exchanges produce in response to legal process.
Can you value the crypto on a specific date?
We can report balances at identified addresses on a date counsel chooses, alongside historical market prices. Which valuation date applies is a legal question.
What if the other spouse says the crypto was lost or spent?
Tracing can often show whether and when funds left the wallet, and where they went. We report what the record shows either way.
