I am the secretary of a self managed company for a block of flats. One of our neighbours is deaf dumb and autistic. He used to have a guardian who kept an eye on his financial affairs, although she didn't live with him. I presume she has died as I have not been able to make contact with her for a number of years. The neighbour has got into financial difficulties with paying his maintenance charges over the last 4 years. I believe he was made a ward of court from a conversation I had with the guardian a number of years ago. Although the neighbour can read and write, he noes not reply to any letters we have sent him. How can I find out if anyone is responsible for him now?
