okay.. so after doing a lot of research I found out that is simpler than it looks to change your last name.
If you want to keep your last name and just use a hyphen, then the process is different because you have to go to court and to tell you the truth is a hassle… so this is how to do it if you just simply want to change it to your new Mrs.
Step 1 — Get court copies
After you got married at court they give you 3 copies of your marriage certificate. Make sure you have them because this is the most important think and proof of your new last name. Once you have this paper you are officially Mrs.—- but to make it legally read on to step 2.
Step 2 — Social Security
first think you need to do is change your last name on your social security card. so grab your passport or birth certificate and head on to the closes social security office. (find out where is the closes one to you by typing your zip code. You can fill in the application when you get there or you can download it from their website and have it ready download here They will send you your new card in the mail in 2 weeks.
first step to change my last name... check!
Step 3 – Driver’s License
Once you have your social security card, make an appointment with the DMV. Grab your passport or birth certificate, your social security card, $10 bucks, a copy of the marriage certificate, and your old driver’s license. they will give you a new card instantly and its official.
Your’ done! Now, you can go to the banks and any other places you have accounts at and request your name to be changed. Some places will ask for a copy of your marriage certificate, others with just showing your social and Driver’s license will do.
