My fiancee and I have been living together for about a year now, but we still have separate addresses. Mine is still my parents, which is only a block away, and her mailing address is her dad's and for some reason her W2 address is her mom's.
How big of a pain is it going to be to change addresses? I.e. tax returns, car registrations, drivers license? I know for mail you just fill out a form and the post office does the rest. Also, we want to combine car insurance policies to try and save a little coin. Is this a pain?
