There are several factors used to determine child support. The most important are the income of the parents and the amount of overnight parenting time exercised by each parent. The more overnights a parent has the less child support that parent pays.
The legislature has created a child support formula which calculates the amount of child support to be paid. The Guidelines are required to be followed by the Court’s except in certain circumstances. Every attorney who practices family law should have a computer version of the Child Support Manual to counsel you in this regard.
A parent cannot ‘threaten’ to withhold child support without incurring expensive problems including criminal prosecution and jail. However, most court’s will work with a payer who has employment and income difficulty.
