The Hawaii Extensive Time-Sharing Worksheet (Attachment To Child Support Guidelines Worksheet) is an attachment to the Hawaii Child Support Guidelines Worksheet. It is used to calculate the amount of time each parent spends with the child. This worksheet is used in determining the amount of child support owed by each parent in a shared custody arrangement. The worksheet takes into account the amount of days each parent spends with the child, the child's age, and other factors. It then divides the total number of days into three categories: Primary Residential Parent (PRP), Non-Primary Residential Parent (NPR), and Shared Residential Parent (SRP). The PRP is the parent with whom the child lives the majority of the time, the NPR is the parent who the child spends the second most time with, and the SRP is the parent who the child spends the least amount of time with. There are two types of Hawaii Extensive Time-Sharing Worksheets: one for a standard shared custody arrangement, and one for a split custody arrangement. The standard worksheet is used to calculate child support for shared custody arrangements where the parents have equal time with the child. The split worksheet is used to calculate child support for split custody arrangements, where the child spends more time with one parent than the other.
