You need to look at the Oklahoma Child Support Guidelines. Go to famliesintransition.com and use the child support calculator for kind of a short form look at for child support. It takes into account the time the child spends with each party as well as incomes. What is not mentioned in your question is what the current custody/visitation order provides. I would expect that you will have to file a motion to modify the current orders. A court ordered modification should be made even if the two of you agree to a change as court orders are what counts if a dispute arises.
