I’ve been living with my two flatmates since November last year and our lease (which is a joint tenancy) expires at the end of this month. I got on with them both really well until a couple of months ago when things started to sour for various reasons.
Last week one of my flatmates announced that she wasn’t going to pay the last month’s rent and is just going to let our landlord take her portion of the deposit instead. I explained to her how selfish I thought this was considering it was a joint tenancy agreement (meaning all the tenants are collectively liable for the rent). And how consequently myself and my other flatmate might end up losing more of our share of the deposit if the landlord choses to withhold some of it for whatever reason. Furthermore, her monthly rent is £30 more than what she put down as a deposit. I also pointed out that she was under a legal obligation to pay all of her rent, but she is adamant she won’t pay and insists that what she is doing is ‘standard practice’. My other flatmate isn't happy about this either but refuses to confront her about it.
I'm pretty sure this isn't standard practice at all...what should I do about this?
