@Chapman95, This is a great question. We do accept what would be called a Third Party Check. One important thing to consider is that you can not submit that by using deposit @ Mobile. You would only be able to deposit via a USAA Deposit taking ATM or by mail. If your going to mail or deposit to a USAA deposit taking ATM, you would want to be sure it is endorsed correctly. If you type " USAA Locator " In the search field on usaa.com you can check for an ATM in your area.
The check must be endorsed as follows:
Line 1 - Originator's signature
Line 2 - Pay to the Order Of (Account Holder's Name)
