After a final judgment has been entered, a periodic review of a child support order will occur under certain circumstances and if financial circumstances of the parties have changed. In Michigan, the review is conducted by the friend of the court office.
Typically, the issue of paternity comes up in cases where an unmarried mother has given birth and is seeking child support from the father of the child, but is unsure of who may be the father or the man the mother claims to be the father disputes the claim. In such cases, a court will order a DNA test to determine paternity. Once paternity determinations have been made through DNA analysis, depending on the custody arrangement, the non-custodial parent will typically be required to pay child support.
In Michigan, when determining a parent's child support obligation, the very first step that the court takes is to figure out both the parents' net incomes. It is important to understand that for the purposes of child support, net income is not the individuals' take-home pay. Instead, the court considers all pertinent aspects of the parents' financial circumstances in child support cases.
Regardless of whether a couple was unmarried with children or divorced with children, at least one parent -- typically the non-custodial parent -- will be required to pay the custodial parent child support for the upbringing of their child. Generally, each state has its own child support guidelines which are routinely followed by the family court system to determine the non-custodial parent's monthly child support obligation.
