My brother and his wife. We have $300,000 in life insurance, and insurance on our big debts, so they are automatically paid off if we both die, plus I have a small whole life policy, and DH has a burial policy, so most of the $300,000 will be available for the boychik’s care (not to mention SS benefits). Brother lives in Hollywood (works in the film industry), so care of a child won’t be cheap, but my brother manages money very well. If my brother predeceases me for some reason, his wife will still take my son (if she remarries, we will have to revisit it), but my mother, assuming she is alive, will be the trustee for the money. SIL is OK with this, because she was actually in some trouble with debt before she got married, and depends on my brother to take care of their money.
Before my brother was married, one of my cousins was first on the list to get the boychik, but she still had young kids at the time. Now her younger child is in high school, and so we decided that maybe she and her husband are entitled to some time to themselves. But she will be the trustee if SIL happens to take the boychik on her own, and my mother is not around.
Once the boychik turns 16, we will visit the possibility of emancipating him if we both die, so he can stay where he is, and stay in his high school. If we are still in Indianapolis, I will probably have family in Indy, and definitely in a city an hour away, as well as in Chicago, who can check on him, and help him pay his bills every month. It will really depend on what he is like when he is sixteen (and what he wants, of course). He is eight now, and he is a little immature, but he is also very well-behaved. He never gets into trouble for the sake of it, and does what he is asked the first time (well, almost every time). I have known people who, in spite of being top notch students, had to do summer school, or take extra classes during the year (correspondence or online) because they changed high schools after their sophomore year, and the new school had such different requirements, that they couldn’t fulfill them all in two years. And leaving you peer group as a teen can be traumatic by itself; it’s all the more difficult to do when you just lost your parents.
