South Korea's Supreme Court sets rules for seizing crypto in civil debt cases
In brief
- Supreme Court Rule No. 3280 was promulgated October 12, 2026, effective November 1, 2026.
- Exchange-held crypto is treated as a withdrawal claim against custodians like Upbit or Bithumb.
- Custodians must disclose a debtor's holdings within one week of a court order.
- Courts can transfer seized crypto to creditors or sell it through licensed providers.
- Self-custodied coins are covered, but enforcement stays difficult, Crypto Briefing noted.
How exchange-held crypto is treated
The rule treats crypto parked on an exchange as a withdrawal claim the debtor holds against a custodian such as Upbit or Bithumb, Crypto Briefing reported. It's a narrow legal framing. It also does a lot of work, because courts can now issue immediate attachment orders against those claims and bar the debtor from moving the assets.
"Custodians must disclose the debtor’s holdings and claims within one week of a court order."
Courts also get provisional measures. A debtor's crypto can be frozen before a final judgment is handed down (so the assets don't vanish while the case is still running, per the report).
Two routes from seizure to payout
Once assets are seized, the rule gives courts two options: transfer them directly to the creditor at a value the court sets, or sell them through licensed virtual asset service providers. Valuation can rest on market values or on court-approved figures.
In Crypto Briefing's analysis, exchanges like Upbit and Bithumb are now explicitly part of the enforcement chain. They're expected to report holdings and claims and to honor transfer bans when a court order lands.
What about coins that never touch an exchange?
The rule covers self-custodied crypto too, meaning coins a person controls through their own private keys rather than a platform. Crypto Briefing noted the practical problem hasn't gone away, though.
Whoever controls the private key controls the coins.
The rule builds on earlier rulings, according to Crypto Briefing's background on the framework. In 2018, the Supreme Court recognized Bitcoin as an intangible asset with property value, and a December 2025 court ruling upheld the seizure of Bitcoin under the Criminal Procedure Act. Rule No. 3280 takes that structured procedure into civil debt enforcement. The outlet said the research behind the rule pointed to a rising number of crypto-related civil disputes as the pressure that made a formal framework necessary.
