I'll try very hard to be neutral, but it's hard not to view this situation as "unusual".
Friend married 12 years, one preteen child.
They live in a council flat.
Wife has a disability which means she can't be left alone for very long. Friend hasn't worked for some years in order to be her carer - claims benefits for this.
Wife does work a few hours per week- possible because of reasonable adjustments and the fact that she's not alone at work. Her hours fluctuate week on week though so it hasn't been possible for friend to get a job around hers .
So, they basically live off her disability benefits, her small wage, carers allowance and tax credits. Once they split he has no income at all. I suppose he'd have to become a job seeker and may be entitled to some benefits himself?
Expectation is that child will spend most time with wife in their current flat.
So there's plenty wrong with their current situation, but how on earth does he go about sorting himself out? Practically, what does he need to do? Obviously get a job, but that's likely to be low paid, no real experience and out of the workforce for a long time. How does he find somewhere to live?
