Records needed for this question
Transition-service agreements, account assignments and cutover obligations.
How to investigate
Map each service to the party responsible during each transition phase before reallocating costs.
An illustrative review decision
During a carveout, the seller may remain liable until carrier-approved transfer completes. Track legal ownership, operating use and billing responsibility as separate dates rather than assuming they change together.
What can lead to the wrong conclusion?
Legal ownership changes do not automatically move carrier billing accounts.
The result to retain
A dated responsibility schedule and unresolved transfer actions.
