A number of businesses claiming to do credit repair have sprung up over time, and while some may provide services that can assist consumers, the actual results of their efforts may be questioned. In some cases, credit repair may require legal as well as financial expertise. Depending on the extent of the problem, it may require simply cleaning up misunderstandings, while in other cases professional intervention is needed.
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.
