How child support is calculated in Louisiana

Child support is calculated based on the couple’s combined, adjusted, income. Each parent is responsible for their proportionate share of the total child support obligation, based on their share of the parents’ combined income. Since child support calculation requires a proportionate share for each parent, it is important to note that 50/50 custody does not automatically mean that no child support obligation will be put in place by the court. After the court has calculated the parents’ proportionate shares, the court will adjust for additional childcare expenses like insurance or other childcare expenses. (La. R.S. Art. 9:315.8.)

The court calculates your adjusted monthly income by adding up all of the money you make and then subtracting money which may be subject to an exception. (La. R.S. 9:315.2(A)(1).) These exceptions include;

  • A pre-existing child support obligation;
  • A pre-existing spousal support obligation;
  • Money paid to support a child from another relationship, in some circumstances; and
  • Extra money earned from overtime or seasonal work, when including it would be unfair.

Louisiana child support generally terminates whenever the child turns 18, but if they are still a dependent and in school it can continue until they turn 19. Additionally, some children with disabilities may qualify to have their child support obligations extended until they are 22. 

Child support can be tricky but don’t worry - support obligations can absolutely be changed if the DCFS identifies any changes in income, employment, and the child’s needs. If you have any child support questions or concerns, schedule a consultation today to address the needs of your case.
