Sister stole her flatmate’s deposit

Ok if you can't block her everywhere you need to tell her you are not your sister's keeper and do not appreciate being harassed. Then ignore her.

All of which have a blocking facility

Just write back and say to the girl .. this is nothing to do with me so please contact my sister. And then block on every platform

Block her.

Sounds Like your parents don’t understand the situation and are making too much of it.

I don’t think your sister has done anything wrong!

I'm Team Sister!

Bollocks to the flatmate.

I think you're getting a bit overexcited over an age-old uni flatmate dispute: deposits.

Yes the other girl may have been filthy here but as I experienced many times, often even with immaculate flatmates, landlords esp in Central London found SOME way to deduct hefty chunks of our deposit. Flatmates always disagree, and need to find some way to solve it.

The girl hired a professional cleaner, no? So it was just the carpet and bed. Again I do believe Central London LLs go for the lowest hanging target. If it hadn't been flatmate's carpet/bed, it might've been something in common areas or your sister's room. I'm not usually the "they're out to get us" kind but I've experienced it with many C. London rentals!

Anyway, you're just making up excuse after excuse to get involved imo: girl harrassing you (drip feed so likely big lie, and anyway just block her), parents can't speak the same language (as your sister?) turns into parents too busy... Your sister is at least TWENTY-ONE, not 12, no?

Block the flatmate. Your sister needs to grow up. If she did get the deposit paid to her there was absolutely no need to be juvenile and wind the flatmate up about it. She should have given it back but hasn't so that is on her. It isn't up to her to withhold it nor give it to anyone else. I'd be more annoyed that she's lived away for uni but is still acting like an immature idiot. Time for her to grow up and take responsibility for her own actions. I'd tell your parents that you aren't your sister's keeper and be firm that you won't be dealing with this.

Surely your Sister is up £600 not £1200. If the flatmate hadn't trashed the flat the full deposit would have been returned and split.

She's up £1000 compared to what she would have had is she'd accepted the landlords offer of £400 and her flatmates proposal of splitting it.

Sorry ignore. I missed the deposit being £1200 each even though you stated it quite clearly!

Just tell the flatmate to take it up with the LL then block them.

It’s actually them that have massively cocked up by sending both deposits to your sister (and I have no sympathy with LLs that don’t protect deposits - they likely cut corners in other ways as well) simply on her say so.

It doesn't really matter that the sister did all the work. Legally the money was not hers. It was £1200 ! That's a lot of money. She literally took £1200 of someone else's money. She told the LL to transfer it to her as the LL was originally planning on transferring it to them individually.

She has acted very badly here. Yes had she not done anything they'd both be down £1200 each but the fact remains it was not her money

Block her and back your sister.

Your sister is an adult, it's none of your business.

Tell your parents you are not getting involved.

Block the flatmate.

If there are consequences then your Sister will have to deal with them.

To be fair to your sister having a flatmate who lives like a pig because she can afford to lose her deposit demanding any of the money back would piss me off too.

The flatmate is not "down" anything, because she trashed the place and was willing to walk away from her deposit, and she wasn't the one who put in the work to figure out that the deposit wasn't protected and get the money back despite the damage. The flatmate can go swivel. Everyone in the OP's family should block her on all platforms and move on.

How much did the landlord transfer to your sister for the deposit. The only figure you mentioned was £400

Good for her. Sounds like she was proactive and that flatmate was a bitch.

Your parents ridiculous assumptions that they have any power here is not your problem.

The sister got the full deposit back because CAB advised her that thr landlord hadn't protected it so the ll coughed up the full amount.
The sister literally is "up" £1200 because she now has the girl's deposit as well as her own

This is a complete non-issue. The police don’t care about half of £400. And no-one is going to sue anyone for that amount! It would cost more in the courts! There will be zero consequences other than your sister having to make peace with her decision. Let your sister have her dispute and you and your parents should stay out of it. Moral obligation, indeed! What nonsense!

Your parents should know it's not your responsibility. Have them speak to your sister themselves. If they can't shame into returning the money are you able to?

Your sister was stupid to give the money to someone else. Nice as the gesture was, it wasn't hers to give.

Block her then. Your parents should do likewise.

For what it's worth I think your sister is morally entitled to keep the money. But she was an idiot for bragging about it.

If your sister hadn't done all the running around and at least had some of the flat tidy then there would be nothing to fight over, so the more I see it the other girl can bugger off. Just listen to us(you did ask for advice remember) and stay out of it

You said the deposit was originally £1200 but they only got back £400 due to the damage in the flatmates room. If the flatmate had not caused that damage then they would both have £600. Besides I thought that the penalty for landlords who do not protect the deposit is up to three times the value of the deposit.
