The simple answer is yes! Unless of course you have given permission or your ex has a court order to obtain a copy of your credit report. If there is a court order, such as a stipulation in a divorce decree then you will most likely have to provide a copy of your credit report to your ex.
If you are really concerned about your ex having access to your credit report go to our credit bureau phone numbers article and contact each of the credit reporting agencies to put a block on access to your credit report. Most credit monitoring or identity protection services offer this type of credit lock too.
