Extremely long story which I won't bother telling (unless someone asks) and it's probably outing but whatever!
My FIL passed away in the summer. DH's brother and SIL have been convicted of several counts of fraud and money-laundering where they stole thousands of pounds from FIL (who had dementia). Anyway, they have been dealt with by Crown Court (the brother is now in prison). The police have lodged S18 notices to them both in order to confiscate anything purchased using FIL's money
However, what has also happened is the SIL (who got a suspended sentence) and her family are keeping my FIL's personal things. I don't mean clothes and that, I mean ALL of his photos, his paperwork and also my late MIL's wedding dress(!). So far they've ignored DH's requests to return the items to him. Unfortunately DH's temper got the better of him today and the message he sent to one of the SIL's daughters was very "to the point" and he had a serious vent about what his brother and the wife have done. Now he's blocked from messaging
My poor DH has nothing from his Dad (or his Mum). He also literally has no photos of himself.
By the way, this is not about money. That side of things is completely out of our hands
Is there ANYTHING we can do?
