My ex husband did not pay me my child support and when I sent him an e-mail stating that if he didn't pay me I would then have to seek legal counsel. His response was very explicitive and basically told me where to go. I have always had sole custody of our son and provided for him as a single parent for over 3 years. When we got divorced we had created a very generous and fair parenting plan for my ex spouse. The problem is that I don't want to fight with him over this but am entitled the child support as directed by Law. If he refuses to pay me can I change the parenting plan to not be as generous. And if so can I do this without the possibility of ex spouse taking my child from me?
