South Korea's top court spells out how to seize crypto from debtors

South Korea's Supreme Court has formalized how civil courts can reach a debtor's crypto. Supreme Court Rule No. 3280 was promulgated on October 12, 2026, and takes effect on November 1, 2026. It lays out the mechanics for freezing, seizing and selling digital assets when someone fails to pay a civil debt.

Crypto sitting on exchanges gets treated as a withdrawal claim — a right the debtor holds against a custodian such as Upbit or Bithumb, not the coins themselves. Courts can slap immediate attachment orders on those claims and block the debtor from moving anything. Custodians must hand over the debtor's holdings and claims within one week of a court order, putting exchanges explicitly inside the enforcement chain.

Self-custodied coins are covered too, though collection works differently. Courts can push assets straight to the creditor at a value the court sets, or sell them through licensed virtual asset service providers. Valuation can lean on market prices or court-approved figures — a hedge against how wildly crypto can swing between a hearing and a sale.

The rule also adds provisional measures, letting courts freeze a debtor's crypto before a final judgment lands so the assets don't disappear mid-dispute. That tool looks built to shut the escape hatch early, though it works best when the coins sit somewhere a court can actually reach.

Seoul has been circling this for years. In 2018 the Supreme Court recognized Bitcoin as an intangible asset with property value, and a December 2025 ruling upheld Bitcoin seizure under the Criminal Procedure Act — a criminal-side decision. Rule No. 3280 carries the logic into civil debt enforcement, with the research behind it citing a growing pile of crypto-related civil disputes.

For creditors, the payoff is predictability: a defined route to crypto held on a domestic exchange, complete with a disclosure deadline and a sale mechanism. For Upbit, Bithumb and their peers, it's a codified compliance duty to report holdings and honor transfer bans. The unresolved wrinkle is private keys — whoever holds them holds the coins, and ordering a hardware wallet to cooperate is a tougher pitch.
