In order to remove the debts created by the identity theif you will need to send an affidavit to the company or creditor holding the debt. When you contact them to close the accounts ask what forms they require. The affidavit permits them to investigate the claim – it does not ensure that the debt will be cleared.
While each business may have its own requirements you can also obtain a free affidavit form at: http://www.ftc.gov/bcp/conline/pubs/credit/affidavit.pdf. Ask the business if they will accept this form or need you to fill out one of theirs.
Send the copies of the affidavit and supporting documents to the businesses (a separate form should be created for each account or institution responsible for providing the identity thief with credit). Do not send original bank or card statements. Blackout any information on the statements not related to the account.
Send a copy of each affidavit and the police report to the credit bureaus. Write a letter requesting the information you declared was a result of theft be blocked or removed from your credit report.
