Restoration is the right framing when most of your negative items are accurate but old. You're not arguing the debt happened - you're working the obsolescence rules and the seven-year clock.
What the FCRA actually says about obsolescence
Most negative items - collections, charge-offs, and late payments - drop off your report seven years from the original date of delinquency on the underlying account. Not seven years from when the collector bought the debt; not seven years from the last payment. Seven years from when the original creditor first reported you 30 days late.
Bankruptcies are the exception: Chapter 13 stays seven years from the filing date, Chapter 7 stays ten. Federal student loans default to a different rule - they can stay until paid in full or rehabilitated.
What restoration looks like in practice
Step one is mapping every negative item to its actual original-delinquency date and writing down when it should fall off. Step two is disputing anything that's still on the report past its date or with the wrong date attached. Step three is filling the calendar - in the years before items naturally drop, you're adding fresh positive payment history (a secured card, a credit-builder loan, an authorized-user line on a parent's older account) so that when the negatives fall off, your file isn't thin.
