The question this page answers

What does final deliverable ownership establish in this file, and what additional fact could change the next step? A buyer wants to change firms without losing essential history and work products.

Identify the person, entity and responsibility separately

Record the legal name, relevant role and source supporting that role. The payer, owner, user and person implementing a decision can be different. Match each document to the specific entity or individual before combining it with another record.

Apply the check to the situation

A buyer expects every planning worksheet to transfer to a new firm, but the agreement defines a smaller set of client deliverables.

For this check, identify the document that supports final deliverable ownership. Compare it with written portability commitment before treating the two records as consistent. A difference may indicate separate events, incomplete history or a correction that has not yet reached every system.

Compare sources before accepting the result

Compare ownership documents, contracts, payment records and operational facts. Flag disagreements instead of resolving them from a bank account nickname or marketing statement. Ask who has authority to approve the eventual action.

Handle an incomplete or conflicting file

Changes in ownership or responsibility can require a new review even when the amount is unchanged. Obtain written clarification from the appropriate professional and retain the role assignment with the final work product.
