I just wanted to mention that I had an excellent experience with the Lancaster DMV last week.
DH and I spent a week at our new home getting ready for me to move down there soon. I set aside one full day for changing over my car registration and driver's license because I figured that's what it would take. Imagine my surprise when it took almost as long for me to drive from SCCL to Lancaster than it did to do everything else (after I left the insurance agent)!
Insurance Office -- 1 hour getting things faxed from PA and getting everything changed over.
Tax Office -- About 10 minutes total first getting my personal property bill then moving over to the second office to pay it. No lines at all.
DMV -- Waited in the reception line about 2-3 minutes because guy in front of me didn't have everything he needed. Talk to reception for about 30 seconds and didn't even get to sit down before they called my number! It did take about 15 minutes to get everything done at the window, but had absolutely NO problems at all! I was even smiling when I left and in a good mood.....imagine that!
The key to this is to first go to the SC DMV website (click on section named "Moving to SC") and print out all the forms that you need and have them filled in ahead of time. I also printed out a copy of the acceptable required documents and made sure I had everything I needed from there. I handed the woman my forms, PA driver's license, PA car title, passport, SS card, and two proofs of residency (checking account statement & house insurance declarations page/payment) and she took it from there. I walked out with a brand new driver's license and a pretty new license plate for my car! I was amazed that I got a real license plate and not a temporary cardboard one.
Now I can't wait to get me moved down there!! DH is staying here until this house sells and then renting a place until he finds a job down there. Really hoping that we sell soon as I would love to get the mortgage paid off right away!
