Louisiana residents seeking child support generally must file through the court in the parish in which they live. To ensure things go as smoothly as possible, it is extremely helpful to include a private attorney in the process. A local attorney specializing in child custody and child support will be able to answer any questions or concerns you may have regarding your case. They can also help you better understand how your income will be calculated and divided as well as determine an appropriate payment amount that gives your child the support they need, among many other things.
