My condolences to you on the loss of your father at an early age and now the loss of your grandfather. You may not have to have an attorney. If your grandfather's Will was validly written and executed, it can't be changed at this time. However, having an attorney who can advise you of your rights and interests in the estate and give you options for dealing with any issues or problems which might arise is a good idea.

I agree with Attorney DiSalvo. The Will cannot be changed. You will receive a copy of it, once probate administration starts. If you do not understand any part of the Will or the probate administration, you should contact an attorney to assist you.
