Week 3- pre production

I have my script, characters, and most of my story board. Next is sound and backgrounds that all souled be done by the weekend. So sometime maybe Friday I will be able to start my first scene. So far I haven't run into any big set backs except for time. but there is one big issue I am having and that has to do with the copywriters to the animation I just need some clarity on who owns the characters and story, I already know the film is owned by the school.
