I've tried googling but no clear answers, hoping someone can help!
Background: husband left two months ago, we have a 21 month old and a seven week old (yes he did leave a month before dc2 was born). He currently puts money in joint account to cover bills but this is an arrangement between us, no court order or csa etc.
I'm currently receiving maternity allowance, child benefit and am waiting to hear about my application for tax credits. Not working and unlikely to find a job that will pay enough when childcare for two is taken into account (plan was always to wait until kids went to school before returning to work. Qualified for maternity allowance due to when I finished work with dc1 and the gap between pregnancies)
At the moment we're living with my parents but this can't continue indefinitely so need to look at housing options. Imagine I would qualify for housing benefit under current situation but how does it get paid, eg do I need to be living somewhere before I can claim hb for it? If so how on earth do I pay rent before the claim goes through? Or can I claim once I've found a place but before the rent is due iyswim? Never mind finding someone who'll take housing benefit in the first place 
I've just read this back and I sound really grabby. I'm honestly not, just can't really work until the 30 free hours for childcare come through for dc1. This was never the plan but clearly my husband didn't get that memo...
