I have searched here and on-line and haven't found anything on this. But one of my name change items is my retired military ID and TriCare through DEERS. Although anything other than a spouse getting a new last name isn't referred to on theirs and other sites, it seems that the proper ID and Social Security Card will support a name change. I suppose having the court order is also good back-up. But to no surprise, I can't find anything on gender change. Is anyone who went through this process willing to share what they found out? Thank you!
