Whether you have a Probate claim, i.e. whether you can apply for the grant and also inherit from the estate, is dependent on your relationship to the deceased. If the deceased has not left a valid Will, a Will, of course, outlines who the executives of this state are and who benefits from the estate, then the rules of intestacy will apply. This may mean that certain people may benefit from the estate that the deceased did not want to. This is why having a Will drafted to reflect your wishes is so important. Where there is an intestate estate, the order of entitlement determines who is entitled to apply for the grant of letters of administration and also who will inherit from the estate.
