Someone taking a look at the Indiana child support laws might believe that the state is aiming to financially penalize parents for a failed marriage. This is because they take into consideration very few factors, such as earnings of both parents, the number of children and the percentage of time that the children are with each parent. This means that the financial needs of the non-custodial parent are not actually considered. Is this uncommon and something unique to Indiana child support laws? Actually, it is not all that rare for the non-custodial parent to see in the area of 30% of after-tax income go to child support. Many states do ask support-paying parents to fill out complicated financial forms to determine their true financial ability, but Indiana is not such a state.
