After you send a dispute letter, the credit bureaus have 30 days to investigate the items in question. They must forward all the relevant information you provide to the organization that is furnishing that information to your credit file. The furnisher must then investigate the dispute and report the results back to the credit bureau. When the investigation is complete, the credit bureau must provide you the results in writing.
