You may have recently gotten married or divorced, had a baby, or simply decided that you no longer want to go by your birth name. Whatever the reason, if you've legally changed your name, you'll need to update your information with your bank.
There is no cost associated with changing your name at the bank. However, you will need to provide proof of your legal name change in the form of a court order or marriage certificate. Once you have these documents, simply take them to your local branch and they will help you update your account information.
