When you can ask for a change in Maryland

The court can change support after a motion is filed and you show a material change of circumstance. It can't go back before the date the motion was filed. A new guideline revision by itself is not a material change. Incarceration can be a material change if it sufficiently reduces the parent's ability to pay.
