How much should I be paying. A divorce is emminent and I don't want to get raked over the coals. I make 48k a year and she makes 16,500 working part time 20 hours a week. We have a three year old. She told me that she will accept 700 plus I have to pay for insurance, split health care costs like copays, and half daycare, totalling about 1000 a mounth. What's fair?
