Generally, you don't have the right to remove negative accurate information from your credit report. Under the Fair Credit Reporting Act, creditors and credit reporting agencies are free to report negative information about you as long as that information is correct. This accurate, negative information can remain on your credit report for seven years in most cases. An exception to this general rule is when your credit report shows accurate, but negative, information multiple times. For example, let's say you have a delinquent credit card account. After a few months of delinquency, the credit card company sells the account to a debt-buyer. If both the original creditor and debt buyer are reporting that you owe money, that's something you could dispute in good faith. Otherwise, it might look like you owe twice as much as you actually owe.
Beware of any company that promises that it can remove accurate negative information. It's likely a credit repair scam. These scams usually prey on people with poor credit. They demand large, up-front fees and promise to get all negative information removed, even if the info is accurate. They try to game the error dispute process by sending repeated and shallow dispute letters in an effort to overwhelm the credit reporting agency into removing the information by mistake. However, the credit bureaus have caught on and this sort of gamesmanship is no longer successful. Save your money and work to rebuild your credit the right way.
