The only thing that will save you now is to make sure he has NO accidents or tickets before he's 25 and hope he gets that job. Or, get him his own policy when he turns 18 and KICK HIM OUTA THE HOUSE.
I've always had this theory. A child is not only a blessing...but an investment. Give him some options. As soon as he begins bring home that paycheck, let him make the choice:
OPTION 1.
Pay room & board, and insurance premiums until you are on your feet, and when ready, you can move out and be totally on your own and owe your parents NOTHING. You can live here as long as you feel you need to, abiding by the house rules of course.
OPTION 2.
Pay no room & board, or insurance. Live here free of charge until the day you turn 21, then you are GONE. You must move out. But...You pay me 10% of all future earnings the rest of your life or mine, which ever comes to an end first.
Too bad it don't work that way, but it's a nice thought isn't it?
