Can a college/university raise the tuition after students have already paid and then charge the students the increased amount?
Usually there are statutes, rules and regulations that preclude such action during the school term, since many scholarships and loans are obtained or applications done for them based on a certain tuition rate. If the school/college/university that you are attending is changing the tuition rate, you may wish to first find out how the school thinks it can do that during a school term (if school term has begun). So ask for statutes, case law and rules and regulations the school is using to justify the position that it is legal or allowable to raise tuition after the students have already paid. Then, contact the department of education in your state and the state attorney general and file a complaint or inquiry. See if that will help alleviate the situation.
