Settling complicated probate applications after Keith Biggs's death

In the past I instructed former probate registrar Keith Biggs to check the wording of complicated probate applictions, including one where the original will had been lost in a burglary and nobody had a signed copy. He sadly died a year or so ago, so can anyone here recommend other people to use?

I have recently been assisted by Probate Support Services ( who were able to assist swiftly, and were very helpful indeed. It is much the same arrangement as Keith Biggs, as they have some retired registrars who do the settling.
