Some of this stuff just plain sucks, big time. I had a friend whose husband took out a $5000 bank loan while they were separated, and though I don't remember how he did this, SHE was solely responsible for paying back the loan. It took her two years to pay it back.
I also knew a man who had GROWN kids, and his wife was a school teacher. She took out student loans in order to get her master's degree, and he went in the computer and pretended to be her to take out the absolute maximum amount of money he could borrow, in her name, without asking or telling her. He took that money, left her, and SHE was stuck with the debt.
There are some terrible people out there, Sammy. I DO believe that women need a credit card in their own name. You are right about that. When my daddy died, my mom went through hours on the phone with the credit card company getting her name on the credit card without his. She is on a fixed income and had to "re-qualify", which may sound like no big deal. But she lost the favorable interest rate that was on that card which actually paid off their car loan every month. She ended up having to bite the bullet and pay the entire thing off because the higher interest rate became higher that the original interest rate the car finance company initially charged. She and my dad had obtained that card specifically to have a low interest rate alternative to pay that car off. It should have been in my mom's name in the first place, since she was in better health. She just didn't know any better.
I do think that many women have crappy divorce lawyers and they end up settling because they are so hurt. Men seem to be so much better able to "move on" when it comes to money and dumping their spouses...
Your friend that owns the business should just go get a different job and close the business, and go back to the court and get this changed. Later on, if she wants to, she can re-start the business.
Your ex is a lazy man, and a jerk, Sammy, plain and simple. It would be one thing if he had taken the waiter job out of desperation because he couldn't find a job in his field. He didn't want to, and he didn't want to support his children either. I'm sorry you got stuck with this kind of man in your life.
