I have just got your notice, and we are involved in FATCA for Probate estates and the transfer of US assets to (usually) U.K. Beneficiaries. If you want some suggestions as to how to complete the needed W-8BEN-E I will be happy to give them to you, if they are still of interest. If you are concerned as to live persons reporting matters, you might wish to contact Nigel Scase at Greene & Greene, Bury St Edmunds, Suffolk who also is involved with FATCA.
