Can't fathom this one out and wondered if anyone has had a similar problem? When my fiance's mum moved in with me, to best meet her care needs, we informed the LA of the arrangement, applying for him to take over the Council Tax at her property and applying for the disregard at mine. This was all fine...I continued to pay the equivalent of the single person's CT, he paid single person at his address. I should add that we forgot to claim any assistance because he is the full-time Carer. Then a relative and his girlfriend needed 10 months accommodation in this area. We offered them rooms with my fiance and a deal on cheaper rent in return for helping him modernise the house which is woefully in need of renovation. The rent goes to fiance's mum to help with her current and future care costs ( mainly day centre at the moment). We also inform the council of a change in circumstances. At this point it all goes wonky. The council gets difficult and declare its a house in multiple occupation, that my fiance has no right to be there, cannot be liable for council tax and shouldn't have had a rebate. His mum is the liable person and is billed as such, even though she is considered disabled enough to qualify for a rebate while living with me. As she has capacity at times, she understands enough to get narked at the mess and refuses to pay any bills....which was actually a jolly large, and miscalculated one! The council refuse to talk to me or fiance without having a copy of the POA....I get a little awkward, having sent a letter from "MIL" giving express consent for them to do so, on the grounds that I don't need to activate the POA for this and am acting as her advocate, with her permission. Much tussling follows and we reach an agreement, of sorts, over the bill but another change is occurring in that the relatives, as planned are moving back home and the property will only be occupied by fiance. I feel the situation cannot remain as an HMO- registered dwelling now but don't know how to handle this with the LA? Shelter and Age Concern have said they are being over-zealous and that cut no ice, so it seems unfair and wrong. I would add that all of this is being done to do what his mum wanted, stay in her community, with her known places for as long as she can. Having two homes keeps her future financial options open at present, gives us time and space from caring and offers the possibility of live in paid care. My partner has also lived in the family home many years prior to either parent getting ill and its his only residence. Just don't understand why he isn't able to take over the CT and whether this is a ploy to imply he has no beneficial interest there. As I asked originally, has anyone else had a similar bad experience?
