I pay my obligatory 17% for my son to my ex-wife. Now my current wife wants me to leave (go figure, I thought I had it right this time !!) We have two daughters, do I have to pay 17% (1 kid) to my first wife and 25% to my second wife (2 kids) or 29% for three kids split between them, this would mean my first wife would only get 10% and the second wife 19% or thereabouts. Either way it's going to financially kill me. 
I haven't been able to find the answer to this anywhere.
BTW This is NY State
