Hello I am a solicitor with over 15 years experience. I will try to help you with this.
Was the tenant in the flat when you bought it? Normally tenants pay council tax on the properties they occupy. Is there a reason why this one doesn't? Is that part of the agreement she had when you bought the property? If you are going to be paying the council tax then I do not see any need to notify the local authority.
yes she was. Students don't pay council tax..?
She would be paying it if she had to, but she doesn't under the law.
I'm just not sure whether we just carry on as usual as the ownership of the property shouldn't matter should it? Just who is in there..?
Yes, you are right. If there is an occupier who is exempt from council tax then the situation will continue and there is no need to notify the local authority.
thank you for your help
