You can dispute the TL with the CRAs, since you are not responsible for the account.
|Total Credit: $240,100||Credit Utilization: 1%||AAoA: 5 years, 7 months||Installments: Car Lease, Marcus Loan||Negatives: 0|
There isn't a universal timeframe. It depends on when the creditor reports the change and how long the CRA's take to update after receiving the updates. If your they have reported/updated and the TL reports terminated or similar you can dispute.
My wife closed a shell gas card that I was an AU on 6 months ago and it still shows open on my reports.
I disputed it and it still shows open with a remark that it was closed by consumer.
