Short answer
A useful missing-doc tracker should show the borrower, file, document requested, owner, request date, last follow-up, blocker, next action, and escalation status. The goal is not a prettier spreadsheet; it is one shared place where processors can see what is missing, what was already requested, and what needs senior review.
Why missing-doc follow-up breaks down
Missing documents become chaotic when requests live across email threads, LOS notes, sticky notes, and memory. The processor may know what is missing, but the next person cannot see whether the borrower already received the request, whether the broker owns the follow-up, or whether the item needs clarification.
Fields every tracker should include
- File or borrower identifier
- Document requested
- Reason the document is needed, if your process allows it
- Current owner
- Request date and last follow-up date
- Next action and escalation status
- Notes for senior review
What can be delegated safely
A trained support layer can maintain the tracker, prepare follow-up drafts, organize received documents, and flag stale items. Senior processors should still control confusing requests, sensitive explanations, final QA, and any interpretation tied to underwriting or compliance requirements.
How Mithras uses this workflow
Mithras treats missing-doc tracking as a strong first pilot because it is high-friction, repeatable, and visible. We can help maintain the tracker and prepare the queue, while your firm keeps communication rules and final review.
Workflow map
Intake review
Compare received documents against the file checklist.
Request creation
Write clear requests with document names and owner.
Follow-up cadence
Track last touch, next touch, and borrower/broker blocker.
Escalation

Practical checklist
- Use one row per missing item, not one vague note per file.
- Track requested date, last follow-up date, and next action date.
- Distinguish borrower action, broker action, third-party action, and internal review.
- Flag stale items before they become closing pressure.
- Keep communication templates reviewed by your firm before broad use.

Should the tracker live in a spreadsheet or LOS?
Use the system your team will actually maintain. Many firms start with a spreadsheet view that mirrors LOS notes and then tighten the workflow over time.
How often should missing-docs be reviewed?
Daily for active files and at least weekly for aging items, with escalation rules for stale or unclear requests.
Can support staff send borrower requests directly?
Only if your firm's process, client expectations, and compliance controls allow it. Many pilots start with drafted follow-ups for review.
