When parties have an equal custodial arrangement, meaning that they share overnights on an equal basis, seven nights in a two week period with one parent and seven nights with the other, there is still the possibility of a child support order. The party who earns more money will be obligated to pay support. If, however, there is a cost for health insurance, this amount will be factored into the guideline calculation. Any cost for daycare or after school expenses will also be factored into the equation. These costs can be significant and can greatly impact who gets paid and what amount. It is a good idea to always get a rough estimate on child support before going to court over these issues.
