Grant de Bonis non - Will followed by intestacy

A died leaving a Will where she appointed B as her sole executor and sole beneficiary. There was no substitute beneficiary in the Will.

A Grant of Probate was obtained in 1999 however the property was not transferred into B’s sole name. B died in 2023 leaving no Will. B has two children. The two children have obtained Letters of Administration in B’s estate.

The property now needs to be transferred to the Beneficiaries names, my understanding is that I would need to apply for a Grant de Bonis Non under Rule 20(c) and that the children of B can apply but would welcome your thoughts. I note that I need to use CAP A5C and PA1P.

A also changed her name by Deed Poll and her Will is referred to by her second husband’s name but the Grant of Probate is referred to by the surname that she changed to following the change of name. I assume that I need a copy of the Deed Poll to show much change of name too as the Land Registry refers to A’s old name.
