As the product of a dead beat dad - parent's divorced when I was 7, dad disappeared, mom died when I was 15, (I have 3 sibs, too - at the time from ages 11-18) dad reappears when I was 17, never paid or contributed a thing. Ever.
Any wonder I had to be married about 15 years to the best man in the world before I finally believed that he loved me and wouldn't leave me? And to be perfectly honest, that's the biggest reason I chose not to have kids - never wanted to put a kid thru what I went thru.
I know in MN, you can have a dead beat dad's driver's license revoked for non-payment, and you can have his wages garnished. Might be worth looking into, Bonnie.
I do like the idea of burying the body, too!
