If you haven't gotten married yet there are a few items that you can take care of before the wedding.
1) Tell your employer
-Change your work email address
-Order new business cards
2) Reserve new personal email addresses, if you'd like one with your married name (Yahoo!, Google, Hotmail, etc)
3) Make your honeymoon reservations using your MAIDEN name. You won't have identification in your new name until a few months after you are married.
4) Determine how many marriage license copies you will need for your name change. Usually just 1 or 2 extra will suffice since an unofficial copy of the license is all that is usually needed for most companies. It's very easy to request extra copies when you send off for the original so make sure you get enough to save yourself the hassle of requesting more at a later date.
After your wedding it usually takes a few weeks for your marriage license to arrive in the mail. Once you receive it, you can start the process of changing your name.
1) Social Security Card
