Asylum seeker own house in country of birth and JSA stoppage

Can anyone help?
My client had a home in Ethiopia but fled with his young family and wife to the UK to seek asylum. He brought no papers with him. He can not return to Ethiopia and has no idea what has happened to his home there, nor can he empower anyone back home to find out because their lives would be similarly threatened if they involved themselves in his affairs.

My client’s JSA has been stopped because he told the DWP about his house in Ethiopia. He has been told to sell it and live on the proceeds. We have been dealing with this for months and can not seem to get through to the DWP that this is an impossibility.

What can we do to help our client? Obviously his family are suffering.

Thank you
