Cryptocurrency has moved from edge-case to default in high-net-worth family law matters. A spouse who wants to hide assets no longer needs offshore accounts and shell entities; a hardware wallet in a desk drawer can hold seven figures, and a financial affidavit can credibly omit it.
Forensic attribution starts with the device, not the chain. Traces of wallet software, seed-phrase residue in cloud backups, exchange-account artifacts in browser history, and login patterns across email and authenticator apps usually reveal wallet ownership long before on-chain tracing becomes relevant. Once attribution is established, on-chain analysis tools can reconstruct transaction history and identify counterparties.
What family-law counsel routinely miss: cryptocurrency is rarely an isolated asset. The same forensic indicators that reveal a wallet also reveal undisclosed exchange accounts, DeFi positions, NFT holdings, and cross-chain bridges. The exchange records often include KYC documentation that ties the account back to the spouse personally.
Three practical points for counsel:
- Move quickly on device preservation if there's any indication of crypto involvement.
- Subpoena exchange records by account email and phone, not just by name.
- Treat the data-room representations as the floor, not the ceiling.
We are routinely retained on the forensic side of these matters and welcome direct counsel inquiries before subpoenas are drafted.
