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.
Law: Md. Code, Fam. Law §§12-104, 12-202(d); Md. Code, Family Law §12-104
