Double Council Tax rules - am I liable?

[RainbowLife]

I live in a relative's home with my disabled son (I own 5% of it, the rest belongs to the relative).

Due to the fairly catastrophic and chaotic end of my very short marriage I have struggled to get the house that used to be my home ready for sale but I'm nearly there now, thank goodness.

I visit to sort it out as often as I can but it's not my 'real home' anymore. A tenant who doesn't live anywhere else lives there, she's happy to move out whenever it's sold but for now it is her 'real home'. She uses part of the house, I've been getting repairs done in the other part and clearing out the remains of my stuff.

Where I actually live should count as my main home for Council Tax but the new rules this year for Council Tax are confusing.

Should the tenant be liable for the full Council Tax even though not using the whole house? If we share the Council Tax should it now be charged at the double rate?

Neither property is empty and both have a permanent adult resident.

Any advice would be much appreciated.

I know it's not a fun topic but I'd really appreciate some advice.

When you say your tenant only uses part of the house, does your tenant have an AST for the whole property in her sole name, with a casual arrangement between the two of you that some rooms need repair and that she essentially allows you to stay occasionally and store some stuff?

If so, I don’t think you need to unnecessarily complicate things here: the council tax is her liability and she can receive the single person discount; you can have an agreement between you that you pay something towards bills to reflect your stays. You then have the council tax liability for your own home - presumably where you live, are registered on the electoral roll, pay bills etc.

Thank you that's really helpful.
