Shared Custody Documentation Package

Who this is for

Families, estate trustees, and fiduciaries who manage a shared cold storage arrangement — typically two to five signers across hardware wallets, paper backups, and safety deposit references. You need a single authoritative record that an incoming trustee can follow without prior technical familiarity.

What you receive

A leather-bound custody binder containing:

Device inventory sheets — model, serial number, firmware version, purchase date, and physical storage location for each hardware wallet
Signer role matrix — which parties hold which keys, their contact details, and mandate scope
Recovery path diagrams — step-by-step procedures for each contingency (lost device, incapacitated signer, estate transfer)
Handover checklists — dated forms for when custody passes between trustees or generations
Glossary of custody terms — plain-language definitions in English with Korean annotations where requested

Process

Intake interview — 90-minute session at our Gwangju office or via secure video to map your current custody structure
On-site inventory (if applicable) — we photograph and catalogue devices without connecting them to any network
Draft review — you verify every detail before binding
Delivery — physical binder handover with a walkthrough session for all active signers

Included

Two revision rounds during drafting
One trustee walkthrough session (2 hours)
Duplicate index cards for safety deposit box reference

Excluded

Legal advice on trust structures or tax treatment
Key generation, wallet setup, or transaction signing
Ongoing monitoring or software subscriptions
Translation of legal instruments

Preparation

Gather a list of all hardware wallets, their storage locations, and the names of every current signer. Do not bring seed phrases to the intake session — we document procedures, not secrets.
