Thanks for your response. I'm a little confused by the legalities of these things, especially as this is uncharted territory. The current tenancy agreement has been in operation since August 2009 and the other tenant was living here as his sole residence. I'll contact the local council tomorrow and clarify the situation with them to ensure there will be no issues.

Hi, I am currently in requirement of a new joint tenant and I'm looking for some advice on a couple of questions. The current joint tenant is in the process of moving out and my LHA rate will not cover the remaining rent. I'm struggling to find a suitable candidate to fill the position. There's one person who is willing to take up the role however, due to other personal commitments, his living arrangements will be split between properties. The property where he is registered at the moment is his parents house, where he is also named on the council tax bill and rent book. Will the process of him being named as a joint tenant on the property have any knock on effect on his parents situation ? Can someone be registered on a council tax bill at more than one property ? Any advice would be greatly appreciated. Cheers
