KML is right about one thing...take out a life insurance policy on him today and do not tell him. You need to do it before anything is put in place as a fall back for your daughter.
Job - this is not legal. He has to agree to the life insurance policy. And ideally, he would be required to pay for the insurance policy (I pay for my policy on my ex, but that's because I don't trust him to make the payments. He insisted I reduce our already-existing life insurance policy - even though I was paying - so that I wouldn't "unduly profit" from his death lol. As if I was going to put a hit out on him for an extra 200k.)
