It didn’t take me that long to get my name changed. It was annoying, but wasn’t too bad.
We had our marriage certificate in the mailbox by the time we were home from our honeymoon (week long honeymoon). We got married in Indiana. The officiant handed it in in person, so it went quick.
Next, I started changing all of my credit cards and anything I could do online. It was annoying and took a couple of days because some places I had to email and wait for a response, but it wasn’t difficult. Didn’t need to show proof. The weekend after we got back, I went to the bank and changed my name on my bank account. With Wamu, just had to go in with my certificate and it was wasy.
Social security was next (at least for me). Since I live in a county that has an actual social security office, I had to go in person to get it changed. The line took awhile to get through, but the process was fairly easy, and I got my new card in about a week. It says it can take up to two weeks, and I’m not sure about the mail in process
After I got my SS card, I went to the DMV and got my new ID. I’m in NYC so it took FOREVER. Almost 3 hours, and they don’t print it in person, you have to wait for it in the mail, and I’m not sure how long that takes yet since I just went Friday.
That said, I think you could probably have your name changed within two months as long as you start right away. It took me probably a total of about 4 weeks, depending when I get my new ID, but if I had gone to social security sooner, it would have been even faster. And this is in NYC. I know back in Indiana they give you your new license/IDs before you walk out the door, so I would guess many other places do that as well. Oh, I also forgot to request a new debit card when I changed my name on my bank account, so still waiting for that as well, but again, that’s just my fault. If you get organized, get a to do list, and make a schedule, you should be able to finish
