# DenQAI: ownership control fieldbook

File-specific companion · 2026-09-10

## Purpose

What is known about a practice’s legal, operating, property, and management control?

**Who:** Market or transaction researcher with legal review

**Records:** Entity filings; licenses and NPI records; deeds; liens; permitted management/ownership evidence; dated source records.

## Complete the file

1. Link market_id and office_id, then record brand, legal entity, property owner, and management clues separately.
2. Preserve source_url, source_date, source_verification_state, and contradictions for each material claim.
3. Seek the next_document_required before changing control_verification_state from unresolved.

## Definitions

- **DBA:** A trade name that may differ from the legal entity.
- **Registered agent:** Designated recipient for legal notices; that role alone does not identify an owner.
- **UCC secured party:** Party named in a financing record; a lien is not itself proof of practice ownership.

## Fictional example

Fictional example: A brand and management company share a phone number, but control stays Unresolved until the relevant agreement and ownership record are reviewed.

## Review and next action

Request the controlling ownership or management evidence for the specific disputed relationship.

Public clues cannot establish every ownership or control right. Legacy source code C needs definition; distinguish property ownership, clinical licensure, and management.

## AI coach prompt

Help me use DenQAI’s ownership control fieldbook. My question is: What is known about a practice’s legal, operating, property, and management control? Explain these terms in plain language: DBA, Registered agent, UCC secured party. Ask one question at a time about the required records: Entity filings; licenses and NPI records; deeds; liens; permitted management/ownership evidence; dated source records. Walk through the supplied fictional example before asking me for inputs. Treat every missing value as unknown, not zero. Do not invent source records, contract terms, legal conclusions, or clinical facts. Use only permitted fictional or aggregate, non-identifying information. Follow this boundary: Public clues cannot establish every ownership or control right. Legacy source code C needs definition; distinguish property ownership, clinical licensure, and management. End with the missing evidence and this next step: Request the controlling ownership or management evidence for the specific disputed relationship.

## AI review prompt

Review my permitted fictional or aggregate draft of DenQAI’s ownership control fieldbook against the file instructions. Check each required field and period, units, evidence locator, assumptions, arithmetic where formulas are actually supplied, and unresolved contradictions. Check the sequence: Link market_id and office_id, then record brand, legal entity, property owner, and management clues separately. Preserve source_url, source_date, source_verification_state, and contradictions for each material claim. Seek the next_document_required before changing control_verification_state from unresolved. Separate facts from assumptions and missing records. Do not supply unsupported numbers or make a professional decision for me. Apply this limitation: Public clues cannot establish every ownership or control right. Legacy source code C needs definition; distinguish property ownership, clinical licensure, and management. Return corrections, questions for the responsible reviewer, and the next action.
