Hello and thanks for using Just Answer.
My name is ***** ***** am happy to assist you with your enquiry.
Your Mother should certainly revoke the appointment of Natwest as Executors, as they ar elikely to charge the earth for a simple procedure.
Provided your Mother still has mental capacity, she needs to instruct a local Wills Solicitor to prepare a Codicil, changing who she would like to appoint as Executors. The Codicil will be a short document, and needs to be signed and witnessed in the same fashion as a Will.
I hope this assists and answers your question.
Thank you Al. You have confirmed what I had gleaned off the internet.
People moan about Solicitors charges, but Bank Executors charges are horrendous!
All the best
