Solicitors draft the legal instrument. The directive supplies what the legal instrument cannot: the inventory, the custody architecture, the location and role of each key, and the sequence of steps required for recovery. It is written to be usable by someone who has never touched a hardware wallet.
Critically, a well-built directive contains no live secrets. It describes the process and where authority lives, not the seed words. That lets it be shared with a solicitor and stored alongside estate documents without creating a new attack surface.
BlockByte prepares the directive, the solicitor briefing pack and the executor instructions; your solicitor reviews and executes the legal documents that reference them.
