Just to let everyone know, even if your ex doesn't do the right thing with life insurance, there is still Social Security. My friend's ex-husband passed away without a life insurance policy, but she gets a VERY HEALTHY amount from Social Security for her daughter. It's about 70% more than she was getting in child support, and she got very good child support. If you have ever seen yours or your ex's Social Security statement, it will say how much the kids' will get.
My ex is supposed to keep a policy on himself for the kids and does NOT. In return, I don't have him as the beneficiary on mine. My spouse is on one through work, and my parents on the other (they will take care of the kids.)
Another thing I wish I had done... My car was paid off by the time we divorced but his (with me as a co-signer) was not. (We each kept our cars). If I had known what was going to happen, I would have demanded he sell his car before the divorce. He has never paid on time- the car should have been paid off a YEAR ago, and he still has an outstanding balance.

: My credit has taken such a hit. There is nothing I can do; since I am on the loan, the lenders wouldn't let me off, even with the divorce paperwork saying it was his responsibility.
