Am i entitled to see my deceased aunt's will?

It's not so much an entitlement but once an estate is opened and the will has been turned over to the Register of Wills, it becomes public record. Anyone, at any time can go to the Register of Wills for the county that the deceased lived in and look it up. I've dealt with the estates of both my parents over the past 4 years and there are huge books there on sliding shelves that contain all the wills that have been handed in to open estates. So anyone can look at one.
