My kids father was recently promoted to captain of a fire department. His overtime and base salary earned him approx 200,000.00 last year... My salary is about 50,00.00 per year and we have 2 kids. We share 50 percent of 1 kid and I have 80 percent custody of the 2nd child. My chlid support is 1300.00 per mo. Based on his income should I file or can I file for an increase in child support? Would I get an increase?
