AIBU to tell my sister she can’t use my spare room anymore?

BrumMum1978 · 17/09/2026 15:56

My younger sister split up with her partner in July and needed somewhere to stay while she sorted herself out. She has a 6 year old son and I offered them my spare room for 6 weeks. I thought that was reasonable and obviously wanted to help her. The agreement was £100 a month towards food and bills.

At first it was all fine. I’m separated from my husband and live with my 17 year old son who is at college. My daughter is 22 and away at university so there is usually plenty of room in the house. My sister and nephew were sharing the spare room and I thought it would be ok for a short time while she found somewhere else. I wasn’t expecting her to be gone overnight but I did think 6 weeks was long enough to get things moving.

The problem is she has gradually started treating the house like it’s hers. She rearranged all the furniture in the spare room and bought a massive television for it. I didn’t mind her making it comfortable but she’s now got all her things everywhere and it doesn’t really feel like a spare room anymore. She has also started using my son’s gaming equipment and borrowing clothes without asking. He came home one day and found his things had been moved around and was understandably annoyed.

I told my sister she needs to stop using his things without asking but she said she was only trying to make the room nice for herself and her son. She said he wasn’t even using the gaming stuff most of the time so she didn’t see the problem. My son is 17, not 7, and he doesn’t want his aunt going through his things. He’s also said he feels like he can’t relax at home anymore because there is always somebody in his space.

She has also started having friends over. I don’t mind the odd visit obviously but there have been quite a few lately and sometimes I don’t even know they are coming until they turn up. The house is small and when there are extra people in it, it feels very crowded. My son has complained about people being in the house when he gets back from college and I do understand why he’s fed up. I’ve spoken to my sister about it but she thinks I’m making a fuss over nothing.

The main issue happened this week when I heard my sister telling my nephew that they could stay here until Christmas. I asked her about it and she said she had told him that because she didn’t want him worrying about where they would be living. I said that wasn’t what we agreed and she said she knows but she can’t just find a council property immediately. I do understand that but she can’t decide to stay for another few months without asking me first. I offered 6 weeks, not until Christmas.

I told her she needs to move out by the end of October. I thought that gave her time to sort something out but she got really upset and said I was putting her and her son at risk of homelessness. She said we are sisters and I should be helping her, not giving her a deadline. My daughter thinks I should let them stay longer because they have nowhere else to go and says it’s only a few more months. My son says he wants his privacy back and thinks I should stick to what I originally agreed.

I feel awful because I don’t want my sister and nephew to be homeless and I do love them. But I also feel like the arrangement has changed without my agreement and I’m now expected to just accept it. I’ve got my own home and my son to think about and I don’t think it’s unreasonable to want my spare room back. I’m not saying she has to leave tomorrow but I do think the end of October is fair. AIBU?

Is she on the council housing list? Even if she is she is not currently homeless so won't be considered as a priority. Typical non urgent wait is 5-6 years in my area

If she does stay she should be paying a lot more than £100pm

BriarTime · 17/09/2026 17:00

Hang on, she took your son’s gaming equipment from his room and moved it into the spare room for her son?! I’ve misunderstood, surely?!

Itsthewoluff · 17/09/2026 17:08

It’s not working out. She’s moved in her head from guest to equal partner in your home.
whether she goes at the end of October or Xmas or Easter is all pushing it to a future problem. It needs to be a now problem for her.

PaulGalicoagain · 17/09/2026 17:12

Write a letter for her to take to the council confirming she is homeless. Get locks for your sons bedroom door. Social housing can take years - 4-5 here and she will know that.
No visitors (its your house) and I would politely ask people to leave if you find them when you get home.
Does she have other relatives she could go to?
I would also charge her the going rate for the room (if she doesn't leave in October).
Taking your sons things would be the last straw for me.

Mulledjuice · 17/09/2026 17:13

so she's going into your room to take your clothes and into your son's room to use his gaming equipment?

"what are you playing at sis? I've invited you into our home and am putting you up at a nominal contribution and you do this. What are you playing at?"

SirenScream · 17/09/2026 17:17

Take back control, undo all the changes she has made & block her from making any more.

FannybygaslightinGovan · 17/09/2026 17:20

£100 pw you say? Does this include breakfast, lunch and dinner? I'm very clean and quiet...

Seriously though, you've done what you can and what would be expected of a family member and now your sis is taking the piss. Off to the housing office with her!

You need to stand your ground. Your dc is your main priority. She needs to look at private renting.

thestudio · 17/09/2026 17:26

There's no way she'll get a council property in under 2 years - and she won't at all if she's got the option of your house.

If you decide to extend it to Christmas, because clearly she's been dicking around in terms of finding something else, you MUST impose strict conditions and boundaries to avoid alienating your son (to say nothing of your own boundaries).

So she puts the furniture back, she never ever goes in any other bedrooms under any circumstances, she cooks for you all three times a week, she has no visitors whatsoever.

That is what a normal emergency guest would offer themselves!

Shinyandnew1 · 17/09/2026 17:26

She’s going to have a long wait for a council house!

I would have turfed her out the minute she reprint lounge, tbh.

She is being so unreasonable, it’s crazy. I’d give her till the end of this month.

Aubin7 · 17/09/2026 17:27

shellyleppard · 17/09/2026 16:02

@tealandteal the council won't help her unless she has nowhere to stay.
Even someone's sofa or spare room is considered a roof over your head.

She doesn't have anywhere to live as this situation is untenable.

Whenthecriwdsayno · 17/09/2026 17:28

Easy peasy, you write her a letter and tell her that she can no longer stay at your home. She takes the letter to the local council and will be placed in temporary accommodation

aCatCalledFawkes · 17/09/2026 17:30

Surely you catch up with her on where she is in the process of moving and you talk to each other. I personally think 6 weeks was a bit optimistic if she's starting from scratch.

I wouldn't personally be upset about her rearranging the furniture or putting a telly in the room as you can just shut the door on that and she won't leave her stuff all over the living room. But borrowing things without asking and having friends over when it inconvenient for you would drive me nuts.

Does she have any money? Has she applied for any houses? Did she get anything out of her divorce etc...

watchingthishtread · 17/09/2026 17:30

She's not going to get a council house while she has a home (ie your home).

Do a bit of research. You are not being realistic. She has no intentions of moving out at Christmas.

Andylion · 17/09/2026 17:31

OrsolaRosso · 17/09/2026 16:01

First of all I think you should have a strong chat with her about overstepping boundaries. She shouldn't be touching your son's stuff, or borrowing your clothes. Be less accommodating on those things, and she will be more keen to move on.

Agreed.

And from the OP, "she thinks I’m making a fuss over nothing." She doesn't get to decide what defines a "fuss" in your home.

WearyAuldWumman · 17/09/2026 17:33

tealandteal · 17/09/2026 15:58

Will she even get a council property if she is staying at yours?

This. The OP might need to write a letter stating that her sister and nephew have been put out of the house. (I've heard of others having to do this to satisfy the council.)

Jellybunny98 · 17/09/2026 17:34

You/she needs to decide what the plan is for her finding her own place.

If she’s looking for a private rental then yeah, end of October she could realistically find somewhere and be moving out.

If she’s looking to buy somewhere then end of October wouldn’t really be doable but end of November maybe if she found somewhere vacant possession & no mortgage issues.

If she’s holding out for a council property then even October 2029 wouldn’t be long enough for her to get somewhere while she’s living with you.

ToKittyornottoKitty · 17/09/2026 17:36

She won’t get housed at any speed if she’s not homeless, is she actually even trying to find something?

TonTonMacoute · 17/09/2026 17:37

YANBU at all.

She has found a nice cheap, comfortable gaffe for her and her DS and she ain't going anywhere anytime soon.

Agree with PPs, do some initial research yourself, and work out a deadline with her. If she's not out by the deadline her rent goes up - substantially!

ginasevern · 17/09/2026 17:44

@BrumMum1978 She hasn't got a snowball's chance in hell of getting a council flat for at least 5 years. If you make her homeless (basically chuck her out) then she'll be considered for temporary accommodation and move further up the list. Is she even on the council list? Is she able to afford private rental? You need to make her homeless otherwise she'll be with you forever. She hasn't got any incentive to move out, has she. And in the meantime she needs to pay a lot more than £100 a month and you need to set some very firm boundaries.

Whenisitsummer · 17/09/2026 17:45

She'll still be in your spare room next Christmas if you don't stick to the boundary you have set.
She needs to be organising housing for herself and her child, instead of focussing on turning your spare room into her own space.

vagnotwhatitwas · 17/09/2026 17:54

I'm surprised by the responses here. I can't imagine making my sister and small nephew homeless. I would suggest, as others have, setting out clear boundaries about how you live together and supporting her to find work (I'm assuming she's unemployed) and a place of their own to live. She can also presumably claim child support from her XP - what is he doing to support his son?

HorseandHeron · 17/09/2026 17:59

At very leasdt you need to tell her that if she is settling in and buying stuff and making the place her own, then she needs to fairly pay her way. £25pw all in for rent, utilities, food etc for two people is piss-taking. Of course she has no motive to move out. Go through your costs with her and ask if she is prepared to start splitting them fairly until she finds a place of her own.

I can't image acting this way though. She's entitled and is upsetting the OPs family life despite warnings, that's not going to change.

CuriousKangaroo · 17/09/2026 18:04

I can’t believe what some people on here are saying. I would never make my sibling and my nephew homeless. I would also be horrified if my child thought it was ok to do that to their aunt and cousin.

I would have a firm conversation about boundaries etc, but they are family. I would extend whatever help I could and I know mine would do the same for me.
