Does child support reverse during the scheduled summer visits?

Short version -- unless your Decree says otherwise -- no, it doesn't.  Consider this holding from the Nevada Supreme Court: Anastassatos v. Anastassatos, 112 Nev. 317, 913 P.2d 652 (1996): CHILD SUPPORT, Abatement for Summer VisitationOne of the issues not properly before the lower court was the Father's request (and the lower court's order) for abatement of child support during the Father's summer visitation.  While acknowledging that any discussion was unnecessary (given reversal for not being properly before the district court), the Supreme Court took "this opportunity to reiterate this court's position on the issue."Citing Barbagallo v. Barbagallo, 105 Nev. 546, 552, 779 P.2d 532, 536 (1989), the Court reiterated that the primary custodian’s "fixed expenses" do not necessarily decrease when the children are visiting the other parent, and that the district court abused its discretion by abating child support during the summer visitation, finding that abatement not "adequately supported."   So unless your court order says something different, no chid support remains in place as ordered throughout visitation with the non-custodial parent.
