The task and the problem
An antitrust review can contain email exports while leaving shared drives and messaging accounts unexplained. Remote custodian source register management makes those differences visible without declaring the collection complete, which is why teams often pair it with e-discovery support for law firms and disciplined discovery coordination outsourcing. The FTC model request is a narrow example of collection and production instructions. This register also works outside an agency request; counsel supplies the actual scope.

What the firm supplies
Counsel supplies approved custodians, aliases, covered periods, preservation instructions, system owners, and a collection protocol. The remote legal assistant receives access to collection receipts and inventories, not unrestricted administrator credentials. A discovery attorney owns scope questions; the technical collection lead confirms extraction details.
How the work moves
| Step | Input | Assistant action | Output | Attorney review |
|---|---|---|---|---|
| 1 | Approved roster | Assign stable custodian IDs and preserve aliases | Identity register | Resolve disputed identities |
| 2 | System inventory | Match each custodian to approved sources | Source matrix | Confirm scope additions |
| 3 | Collection receipts | Record collector, coverage, and export identifier | Collection links | Exceptions only |
| 4 | Coverage comparison | Flag absent systems and unexplained date gaps | Gap queue | Decide remediation |
| 5 | Technical signoff | Freeze version and attach unresolved questions | Review handoff | Approve next use |
Illustrative example
Fictional matter Orchard involves three approved custodians. An email receipt exists for each, but one receipt says nothing about chat. These invented counts are inventory details, not results.
| Custodian ID | Approved source | Evidence received | Open issue |
|---|---|---|---|
| C01 | Receipt R11, full stated period | None recorded | |
| C02 | Chat | No receipt | Technical lead must confirm availability |
| C03 | Shared drive | Receipt R14, end date omitted | Coverage unresolved |
The assistant does not infer that missing chat means no messages existed. A new row records the technical lead's explanation and links any replacement receipt.
Deliverables, missing information, and escalation
Deliver the register, receipt folder, alias crosswalk, and unresolved-source list as an outsourced paralegal support handoff for attorney and technical review. Acceptance requires a traceable receipt or an explicit unresolved status for every approved source. Escalate departing custodians, shared accounts, inaccessible archives, and conflicting retention explanations. Neither inventory closure nor a custodian acknowledgment establishes legal compliance. Counsel controls any preservation communication; the assistant prepares drafts only.
Systems and responsible AI use
Use only firm-approved systems and restrict confidential or privileged information to approved recipients and approved AI environments. Use access-controlled tables with change history and stable links to evidence. AI may suggest inconsistent identifier formats in an approved environment, but a person checks each suggestion against the roster. Do not upload mailbox contents to unapproved tools or allow automated collection, notices, submissions, or legal-date calculations.
What the firm could measure
- Weekly receipt coverage: approved source rows with linked receipts divided by all approved source rows, from the register; report unresolved coverage separately.
- Weekly clarification age: elapsed business hours since an issue was assigned, from the queue. This measures coordination, not collection sufficiency.
Practical questions
What if two custodians share a mailbox?
Retain both relationships and one source identifier so an export is not counted twice. Keep a note explaining the shared access and let the collection lead confirm how it was collected.
Can the assistant add a newly discovered phone?
Record it as a proposed source and ask counsel and the technical lead about scope and preservation. Do not access or export the phone merely because it appears in a record.
Does a green row mean production is complete?
No. It means the defined inventory check passed; review and production decisions remain separate. Use separate fields for inventory, review, and release status so the handoff cannot imply agency compliance.
