Is my previous employeer required to pay out unused Personal and Vacation time?

I was recently fired and I just received my last check. On my check it shows that I have 31 hours in personal time and 16 hours in vacation time that was unused. I checked over my contract with the company and it does not mention anywhere what would happen with unused vacation and personal time should an employee be terminated or quit. By law, should he have to pay this to me? If so, what steps should I take next to ensure I am paid for my unused vacation and personal time?
