Dispute letters to consumer reporting agencies/background check companies are not complicated, but you may want a background check attorney at The Weiner Law Firm LLC to help you with the process.
The dispute letter should inform the consumer reporting agency/background check company that:
you are disputing information in your consumer report
you are asking for a reinvestigation
as part of the reinvestigation, you are providing the background check company with as much information as you have to support the dispute.
