Can't seem to find a straight answer from anyone else, so here goes.
Niece is 24, lives at home with parents (privately owned, parents pay council tax). Niece wants to move in with partner next year (26, privately owned, pays single person council tax).
Niece is currently staying with partner on weekdays, goes home at weekends (4 days with partner, 3 days at home). At what point should she be paying council tax? Is it when she moves in fully, or should she be paying it now?
Can she get 'in trouble' for staying there majority of time without paying partner's council tax i.e. full rate, not single person discount?
Not sure if this is relevant but the 2 homes are in different boroughs but same band of council tax.
TIA!
