The surname change process is pretty easy, especially in the United States. You're going to have to fill out a name change form and pair it with a show-cause of legally changing your name. Once you bring these forms to the court, you'll usually be granted permission without much hassle. This is pretty much a job well done, and you can start using your new surname name immediately. However, in certain states, you will be required to announce the change publicly by posting it in a newspaper.
