Judges may use a child support percentage to determine how much the child support payments are going to be for the non-custodial parent each month. While several factors are taken into consideration, some states simply require the non-custodial parent to pay a percentage of his or her monthly income to the custodial parent for the financial needs of the children. While this percentage differs in each state, it is roughly around 15 to 20% of the non-custodial parent's paycheck. Individuals who fail to pay thier child support can suffer many consequences, from losing their driver's license or having thier wages garnished to having winnings taken from them or even going to jail. A child support attorney can help non-custodial parents receive the fairest judgement possible when it comes to child support percentage. Since attorneys who specialize in this field know the laws very well, they can arrange for the non-custodial parent to pay an amount which will take care of the children, but which will not completely take all of the money they have.
