Understanding Custody Chain Documentation for Small Firms

Custody chain documentation answers a straightforward question: who held authority over reserve assets at each point in time, and who authorized each movement?

The Three Elements

Every custody chain entry should record:

1. The asset — wallet identifier, reserve type, and amount
2. The authorization — who approved the movement and when
3. The evidence — receipt, confirmation, or signed memo supporting the entry

Without all three, a ledger entry is an assertion, not a record.

Common Gaps We See

Informal approvals. A verbal okay from a senior partner is not documentation. Capture approvals in writing, even if brief.

Shared credentials. When multiple staff access the same wallet without individual access logs, custody chain breaks down. Assign named key-holders and log each access.

Delayed recording. Entries made weeks after the transaction often contain errors. Record movements within 48 hours while details are fresh.

How This Fits Your Ledger

In a Page Maple Core engagement, custody chain documentation appears as a dedicated section cross-referenced to the chronological transaction register. Reviewers can follow any entry from authorization through evidence without searching separate files.

Starting Point

If you have never maintained custody chain records, begin with your three most recent reserve movements. Document the full chain for each. The pattern you establish will serve as the template for all future entries.
