Indeterminate

Case description

A Bitcoin holder discovered in 2023 that a hardware wallet purchased as a gift in 2021 had been initialized by the gift-giver, who had generated and retained the seed phrase 'for safekeeping.' When the relationship between giver and recipient deteriorated, the seed phrase holder refused to provide the backup. The recipient had legal ownership of the Bitcoin but no technical access to it, and no legal remedy that could compel production of a memorized seed phrase from an uncooperative individual.
