Case description
A Bitfinex account holder died in November 2018. Their estate found the account had a significant BTC balance. The exchange required a court order specifically referencing the Bitfinex account, a notarised executor appointment letter, and a signed customer agreement from the new account holder. The process, involving three countries' legal systems, took seven months.
