We went through this about a year ago (?) at U-M. We got the postcards. I had to scan in a copy of my marriage certificate and submit it to a website. I did not feel much indignation toward the process. EMU may run a very tight ship, but at U-M it can be much cheaper and more efficient to outsource a project like this to an experienced third party. The alternative to this process is for the adasiiitrmtnon to jack up your premium contributions faster than they already are.
