Brief background to post - my dad didn't get on with his mum and was brought up with by his gran. His mum died in 2009 and I have recently found out that her estate has fallen to the crown (quite a substantial amount).
My parents live abroad, so either they don't know about the money or are not interested. They do know she died but they had not been in contact for 30 odd years.
Should I let them know about this or leave it? Genuine question.
