Obtaining more placement of child & pay less childsupport, if this is what the kid wants, but his mom denies any requests.

Asked in De Forest, WI - over 1 year

My husband has Joint custody he was granted in the divorce, he gets his son everyother weekend he had to pay childsupport. The son's step dad had a job offer in Ohio, they would stop child support if he allowed him to move, that took place.A year later they moved back, The son likes to come here every other week in the summer he wants to come every weekend,(he is 14), so 6 years after being back in WI, the mom decides to get Child support again, stating her husbands Cobra ins. is about to run out, We have offered to cover him on our Health ins. the mom denied becuase she can add him to hers at no cost,(which is why she wanted Child support) She also denied us to have him more and said she allows him to see his dad. Would it be easy to get more placement of him and pay less child support?
