My grandfather left me money when he passed away. I am 18 almost 19. How do I go about getting this money?

You will need to contact the person or entity that is the trustee of this fund for your benefit. It may be necessary for you to determine the identity of the trustee by referring to the records of the court where your grandfather's will was admitted to probate. You should not count on getting these funds by the time your tuition payments are due, because, among other things, it is not clear that you are entitled to be paid the money now merely because you are an adult. You need to refer to the terms of the will to determine when the funds will be paid to you and under what circumstances.
