Trying to get on fiance dental insurance but hit a "snag" can anyone help me with this?

My fiance got the ok from HR to put me on his dental insurance as "domestic partner" since we live together. The problem is he STILL had his exwife listed on there too and we did not know it! They have been divorced for over 5 yrs and "he" said he told them and they must have made a mistake. HR took his exwife off NOW but my question is be it his fault, his works or the insurence company is this going to delay me getting coverage? Also how can your exwife be on your insurence for 5 yrs and no one know? I can't call his work as he told me he'll take care of it

I left an ex on my insurance for over two years after we broke up. Completely forgot I wasn't alone on it. It happens, and no one I worked with then was so interested in my life that they were going over my papers with a magnifying glass. You pretty much just check "renew" and it's done. Whose fault it is depends on whether he only told HR he was getting divorced and just expected them to change everything on their own, or if HR can even change the terms of an employee's coverage without him signing anything. If you're in all kinds of tooth pain, just pay the dentist. You are actually no worse off with the delay, since you aren't even *less* insured than you started. You've gone from uninsured to still uninsured.
