Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How much is involved?
Have you considered simply sending her a cheque?
Did the deceased have any children, are(or were) his or her parents alive at the time of his/her death ot are there brothers and sisters
Are you aware that a phone call costs more?
is the son alive?
Then I suggest that you use a tracing agency to ensure that you have the correct address for the beneficiary.
You then write a formal letter informing the young person that she is entitled to these funds and enclose a form for her to complete with her bank details.
Go on to say that if she does not accept and wishes to disclaim the inheritance then she needs to sign the short form that you also enclose ("I xxxx wish to discaim the inheritance I am due from xxxx)
Say that in the event that she does not take the money it will go to her Grand father and that if you do not hear from her within 28 days then you will assume that that is whay she wants
Make sure that this is personally served on her (the cost comes from the funds you hold)
If she does not reply then I am afraid that the money belongs to the Son in Corfu.
Please ask if you need further details
Legally you have no choice - and the son could sue you personally for the money if he finds out about the situation after the disclaimer
You are most welcome I hope all goes well
