TMD, the FCRA laws state that accurate negative information will stay in the credit file for a period of seven years except bankruptcy that stays for 10 years. No collection agency or a credit repair package can remove that negative mark before the due period. Only the federal authorities have the rights to remove if the item is placed as disputed.
Sometimes people try to remove the negative information from the file before the legal time period. In cases of bankruptcy, a person's file remains in the court for two years and afterwards, the file is entered in the electronic system. Someone with illegal intentions places the bankruptcy as 'disputed' with the bureau. As a result, the CRA tries to verify the item with the court and as expected, the file is not found. Thus, the bankruptcy is removed from the credit report. But remember, if the person is caught in the act, severe legal actions will take place.
There are credit repair packages that claim negative information can be removed from the file. This is legally not possible. If the company claims to do so, they are trying to make some money from you. Be careful!
