To think he should claim job seekers

[starrieskye]

Aibu to think he should put in a claim for jsa not keep thinking he'll get a job any day. Filled with great plans but no money, £400 left and nothing else.

Without information no one can advise you. It sounds like a brother or close family member who can't claim for themselves so far if it is you can claim on their behalf other benefits (it's been a while so I don't know which would apply plus it would depend on the cirumstances) if it's a case of a perfectly able adult not claiming them you can't bear that resposibility it's theirs to either claim or not for some it's a pride thing.

Your promise to look after someone does not mean ruining yourself. You should advise him on applying for benefits and looking for jobs but make it clear that your money is not his!
Your parents were obviously anxious that this man could not look after himself or they would not have sought your promise. So what makes you think they expected you to support him financially?

if there is some kind of illness/mental health issue at play here, you can look into being an appointee and claiming esa on their behalf

been there done that, its hard but there are options
