After 10 years since divorce, my ex is making noise about increasing child support. When we divorced she was unemployed. I gave her everything plus 18 months of alimony(she claimed that she was going to go to school). My mistake. Only thing she ended up with was a larger bust size. Anyway, that is water under the bridge. My income has stayed almost exactly the same since the divorce. She has remarried, divorced, and remarried the same guy. She has a good job with a university and makes about 1 1/2 times my income. She has purchased the house behind her and rents it out. What are the chances that she can get an increase in child support? Is it as simple as just the cost of living increase being factored and a new amount set in place? Is it a fact that my wifes income is protected from my ex? Thanks in advance.
