what can. you do about a grandpatent who is controlling a custudt issue in stead of the father evev after the judge told hef to stay out of it

Your question is not really clear as to either the current facts, the current order, or your request. Whoever has the child more than 60% of the time, if anyone, is the primary custodial parent.  Otherwise, the parents have joint custody.  See materials posted at: http://willicklawgroup.com/child-custody-and-visitation/ If there is a primary parent, the other should be paying child support.  If custody is joint, support is determined by "offset."  See the materials, and explanation, posted at: http://willicklawgroup.com/child-support/ If the current court orders do not match the facts "on the ground," see a family law specialist about making them match.  And if they are not acceptable to you, because of third-party intereference you wish to eliminate or otherwise, speak to a qualified lawyer about modifying the order to make it acceptable to you.  I don't know if anything more specific can be made of your question.
