When the bureaus and data furnishers receive the dispute and supporting information, they then work with the credit repair company to determine if the item should be removed from your credit report. The major law governing your rights when it comes to credit reporting is the Fair Credit Reporting Act, but it isn’t the only law on your side when it comes to credit repair.
If you find information that is incorrect, you can file a dispute. Remember too, that items on your credit report that you don't recognize could also be potential signs of fraudulent activity — someone working to secure credit in your name for their own use. Make sure you're clear on items that could potentially be fraudulent, versus those that may simply be inaccurate.
