The amount of time you spend with your children affects the amount of child support you pay. This means the parenting time agreement you settle on will impact your payment amount since it will be determined by the time the children spend with each parent. If primarily in the home of one parent, the other parent must contribute to the ongoing support (section 3 of the guidelines) by paying the appropriate support to the other parent.
If the children spend roughly equal time with each parent, then the support is usually offset. It is important that the agreement is properly ordered in shared parenting time support arrangements for the purposes of collecting tax deductions and benefits to which the parent(s) may be entitled.
Child support is the right of the child. Courts will not allow divorces or agreements that do not provide proper maintenance (support) for the children. Parents can make agreements that would not be available to the court to order, like the family home in exchange for lump sum future support payments, if they can defend that the arrangement provides the maintenance that the children are entitled to.
