Removing Negative Credit
Step 1: To dispute a negative item on your credit file you need to first identify the negative items that you want removed.
Once you know which items to dispute, DO NOT complete the Dispute Forms that the Credit Bureaus included with copies of your credit file that they sent you. It's much more effective to easily follow the outlines of these sample letters.
Be sure to include a copy of your credit file and keep the original for your records. Highlight or underline the items you are disputing. Mail the dispute forms to the address listed on each credit file.
To dispute an inquiry, simply write that you never applied for credit with that company.
Make a photocopy of your dispute letter for your records and be sure to send it by Certified and Return Receipt Mail from your local Post Office. Mail your dispute form to the address provided with your credit file. Repeat the above process for each item that you want removed or changed.
Step 2: After reviewing your updated credit file and finding that most or all the negative items have been removed, you may now focus on building a positive credit profile. Positive information will always outweigh a few negative items that may remain on your file.
Step 3: This technique is extremely effective in removing any negative information that was supposedly verified as correct after your dispute.
Important: Always remember that if the dispute is sent in from anyone other than you, the Credit Bureau will suspect that you have paid someone to repair your credit. This raises all sorts of Red Flags. Since they make so many mistakes it is imperative that they believe you are working alone and trying to fix a real legitimate mistake.
If there is a negative item that you want removed from your credit, such as a bankruptcy, charge off or collection account, you may want to write that this is NOT your account and you want it removed immediately.
If the account is now paid off, but was seriously past due at one time, DO NOT write that it's not your account. Instead, write that it is your account but was NEVER past due and you need it updated to say that everything has always been current.
An Extremely Powerful Technique...
This auditing technique is usually only practiced by attorneys. It would be very expensive to hire attorneys to do this for you. However, by following the instructions you'll get similar results as any attorney (you just won't have to pay).
If the Credit Bureaus were able to verify any disputed information as correct, it would remain on your credit file. So you'll need to contact the creditor who is reporting the information. The creditor who reported the item is listed on the left or bottom of your credit file. If their phone number is not provided, call directory assistance in their city and ask for the creditor's telephone number. Call and ask them to mail you written proof and documentation that this is actually your account, since you do not believe the account belongs to you.
Almost all creditors and collection agencies use computers to store information about debtors and they throw out original, signed contracts along with other original documents. This makes it easy for creditors to store and organize information BUT makes it impossible to actually prove the account is really yours and not just another mistake.
Federal Law requires that upon your request, all creditors must show you written proof that the account in question is in fact yours. Written proof is a copy of the contract you signed with the original creditor. As we explained before, you are stored on the creditor's computer and chances are excellent that they have thrown out all the proof that this is your account.
The only creditors that may have proof are the courts (Recent Bankruptcies, Unpaid Tax Liens, Unpaid Judgments & Unpaid Child Support).
Again, all Federal Laws are in your favor. If you say an account is not yours and the creditor does not have written proof that the account belongs to you, they must remove the account from your credit file and cease all collection activity. If they don't have written proof that the account is yours, there are two ways to get the item removed

I wish you the best of luck. I have a few friends in a similar situation.
