The "Cold Wallet" Defense: How We Subpoena Hardware Devices

By Rollan Abdalov December 28, 2025

A common scenario in 2026 divorce litigation: The husband admits he owns crypto, but claims, "I lost the USB stick (Ledger) and I don't remember the password."

This is the modern equivalent of "the dog ate my homework," but with millions of dollars at stake. Courts are becoming increasingly impatient with this excuse, but you need the right technical leverage to expose it.

1. The "Lost Key" Fallacy

Most hardware wallets generate a 24-word recovery phrase (the "Seed"). Sophisticated users store this seed in multiple locations (steel plates, cloud notes, safe deposit boxes). A "lost device" does not mean lost funds.

Forensic Tip We subpoena the purchase history of the device. Did he buy a "Billfodl" (steel backup plate)? If so, the seed is likely physically stored in the home/safe.

Our team frequently assists counsel with these specific discovery requests in high-net-worth Southlake divorce cases and across the DFW Metroplex.

2. Tracing Without the Device

You do NOT need the physical Ledger to value the assets inside it. You only need the Public Address (XPUB).

"Once we identify the Public Address from a bank transfer (the outbound transaction), we can view the entire contents of the Cold Wallet on the public blockchain. We can tell the Judge exactly how much is in the 'lost' device."

This shifts the burden of proof. We present a report showing: "This wallet holds $1.2M. The husband controls the keys. If he refuses to produce them, the Court can offset other marital assets (the house) against this value."

Don't let hidden assets compromise your client's settlement.

3. The "Decoy" Wallet

Spouses often surrender a "decoy" Ledger holding $5,000, while hiding the real one holding $500,000. Our forensic analysis maps the entire cluster of wallets connected to their identity to ensure no secondary devices are omitted.

Conclusion

Don't let the "I lost it" defense stall your case. Use blockchain forensics to value the asset remotely and force a settlement.
