we have a will, in the case of one of us dying, the other will get full life insurance and obviously the kids no exception, but if we both were to go, we have named my bil and his wife, they will get the life insurance and bring up the kids, payable immediately (with a small sum left in trust for the kids, but i feel it more important they have a good upbringing rather than a huge lum sum at 25)
we discussed it at length and although i would prefer someone from my side of the family, all my siblings have kids of their own and even though they would take on more, i don't think it's fair, my parents have raised their kids and should enjoy their retirement, my bil could never have kids and has a great relationship with dd, so they are only happy to do it. it's a running joke at christmas how rich they will be if we were to die together....
i am a very organised person and i just think it makes sense to have something in place, i also have a list of things i want my kids to do if i die and they are left with my husband, just the wee ideas i have about their upbringing, eg. no tv in their rooms, sunday dinners at home etc i know he'd probably not do it, but at least they will know how i wanted things to be. he just noted that i wasn't allowed to let them support manu.
