It seems like there are a million post-wedding things to do. I got home, our house was a mess, and it was rough for a little bit. Our first priorities were to take care of health insurance and fix the messed-up marriage license. I am self-employed so mine sucked and was expensive, while FH’s is cheap and good since if you don’t do it within 30 days of the wedding, you have to wait until open enrollment.
Other important things we did:
got long-term birth control figured out (as I said above, my health insurance sucked and I would have had to pay full price for my IUD- instead, I took the pill until I was on his insurance)
get FH moved in
get rid of duplicate stuff
added FH to my car insurance (I got a refund on my premium, yea for the marriage discount)
name change- go to Social security, then DMV
If you’re combining finances: adding each other to ban accounts, credit cards, etc. (some I did at the same time as my name change which made it easier)
If you’re combining finances: (optional but recommended) set up a budget and figure out how you will manage money. we use mint.com, which tracks everything and even alerts you when a fee is charged to your credit card, you get near your credit limit, etc. And it’s free!
unwrapped the gifts and found homes for them
unpacked honeymoon stuff
cleaned the house (the week of the wedding, I was sick and my family was awful, something had to give)
some people have to pick their wedding prints by a deadline- our photographer rocked, he just gave the CDs with all the pics and we can print them whenever we want
wedding dress preservation or sell the dress
sell any wedding stuff (I’m still working on this one)
divy up household chores
That’s all I can think of off the top of my head. Good luck, feel free to ask if you have any questions, and congrats!
