The problem is if she is no longer renting down south then I’m not sure if this is possible as she needs to provide an address. It might be possible to claim just her own money’s worth (IYSWIM) if there is an option to say she is not a tenant or homeowner of any kind, as in if one of the options when filling out the housing circumstances part of the form is “Living with friends and family” or similar.
However, it then gets complicated and I wouldn’t advise it or think it was appropriate to do that because if he also has a UC claim and they are using the same address, well then there are 2 working able adults living in the house, and it would not be right to claim separately. It’s definitely something an advisor would need to be consulted on as I’m not sure what they’d do in her housing circumstances if she isn’t on the tenancy.
Honestly though? I think she is leaving herself incredibly vulnerable. Does she have her own home in the south? She’s not on any tenancy agreement with him, if she doesn’t own her own place or still pay rent she’s left her own property willingly (so no chance of being considered unintentionally homeless) and she doesn’t have her own income. There are so many things that could go wrong in this situation that would result in her being without a stable home. Is she planning to go on the tenancy?
They also make you job search full time now so it would be much better for her to just work. That way at least she wouldn’t have to rely on benefits which are paid circumstanially and capped. She’d be better off making a small contribution to the rent and bills (with the promise of equal or fair contribution once it’s jointly her home) and bullding some of her own savings.
Just based on her circumstances I’m rather getting the impression that things aren’t stable or guaranteed with this new relationship - is that accurate? Why has she made such an upheaval of her life to move up there with no income and no stable home, was she financially struggling when she lived down south?
