I'm going to turn my ex in for not paying child support
Why would you turn your ex in for not paying child support?
I am owed a lot of money
If she is expected to pay child support then she needs to follow through. If she didn't pay you the child support on time then you definitely should turn her in. Otherwise, she might stop sending you money because like you said she is irresponsible.
Bingo, so I should do it then?
I think that would be the best the longer it carries on the harder it will be for her to make payments. You kid needs that money now and the court can dock her paycheck before she can hide what she makes.
