The Arizona 2015 Child Support Guidelines are a set of rules and regulations that determine the amount of support a parent is required to pay for their child or children in the state of Arizona. These guidelines are primarily based on the incomes of both parents and the number of children involved in the situation. The Arizona 2015 Child Support Guidelines include five different types of guidelines including: Basic Support Obligation, Shared Parenting Obligation, Split Parenting Obligation, Minimum Support Obligation, and Unemployed/Underemployed Parent Obligation. The Basic Support Obligation is based on the combined incomes of both parents. The Shared Parenting Obligation applies when both parents share equal parenting time. The Split Parenting Obligation applies when the parents share parenting time in a non-equal manner. The Minimum Support Obligation applies when the combined income of both parents is below the poverty line. The Unemployed/Underemployed Parent Obligation applies when one parent is either unemployed or underemployed. The Arizona 2015 Child Support Guidelines are used to ensure that children are provided for financially and that both parents fulfill their obligations in providing for their children.
