My son owns a co-owns (33%) a house with an ex partner. She had tenants in the house who have just been evicted. The house is to be sold. The local council has come after him for council tax. They are saying that he is responsible for 100% of the tax even though he only owns one third of the property. His income after tax is £16000 a year variable and usually lower and the council tax is £2500. He cannot afford the £200+ a month with all his other outgoings. So I have two questions. Is he liable for 100% of the council tax? Is he able to claim any sort of council tax relief? Thank you
