We had trouble with one of our sons. I had to set up a system with his teachers to help me monitor it. My son would write the assignment in his notebook or the words "no homework". Then he would go to the teacher at the end of class and have them sign the notebook. I could see each night what the homework was. It cured everything and he ended up loving a couple of his classes because he really got into them this way.
