Yep! I did it myself and it wasn't much of a hassle at all. I think I started about 60 days out?? I sent in the forms printed off of the website that you get right here:
Marriage License Mail Away Info. Make sure to click on the PDF link and not the box that says view forms. I sent those forms in, and received back our license application along with another form we had to sign. My husband and I went to our bank to have the application notorized after work (our bank is open later on fridays and it's free to have documents notorized.) and mailed it back. They sent the notorized copy back with their notorization as well and then we brought that to our wedding. We gave that to our officiant and he signed it (and notorized it maybe?) and sent it in. I recived our actual license in the mail about 2-3 weeks after the wedding. It's a lot of back and forth, but really not too difficult!!
