If you own significant assets in the England and Wales regions of the United Kingdom (UK), it's a good idea to create a Will. Without a Will, your legal heirs would have to apply for a grant of letters of administration. But if you do have a Will, then your legal heirs will need to get a Grant of Probate to act as your personal representative (PR).
Richard Smaller, Senior Associate Solicitor, Irwin Mitchell, a full service UK-based law firm, said to ET Wealth Online that a Grant of Probate (or a Grant of Letters of Administration if a person does not have a Will) shows that the individuals to whom it is issued are the deceased’s personal representatives (PRs) with the legal authority and responsibility to manage the deceased’s estate.
