My question involves child support in the State of: Tennessee
My ex-wife and I share 50/50 custody of one child. At the time of divorce she made 75k per year, I earned 40k. We agreed to her paying child support in the amount of $250 per month and she would get to claim him on her taxes. One year after our divorce she re-married and later that year she gave birth to their child. They soon discovered the child has a serious genetic disease. She went on leave from work, and I told her not to worry about paying me child support since she wasn't working. She just recently resumed working again, only now it is part-time and she is making 18k. She is now suing me for child support based on her new income because she says she needs the money. I asked her why she doesn't go back to working full time (they are still offering her 75k) and allow her husband (who works part-time learning to become electrician) to care for the child to ease their financial woes. She says she doesn't trust that he can care for the child as well as she does. I've helped her in every way I can, but now that I'm newly engaged and my fiance is on bed-rest with twins, I absolutely cannot afford the $350 a month she is asking for. I am struggling financially and on the verge of losing my home. They have a nice home and 2 very nice cars (unlike myself) and their wealthy families are paying their mortgage and car notes for them since she isn't working full time. She also receives money from a charity for children with this disease. Although she doesn't claim the money she receives in help from family (I'm not sure if she claims the charity money), does that go toward her income? Can she just choose not to work full time because she doesn't "trust" her husband or her family with her child's care, and leave me footing the bill?
