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?

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

Cantstopeatingjaffacakes · 17/09/2026 16:00

You asking her to leave is probably the only way she’ll be classed as a priority for council housing. She might have to go into temporary accommodation until they find somewhere permanent but they won’t be out on the streets.

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.

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.

Theraffarian · 17/09/2026 16:03

I’ve just checked the waiting time in my local area for someone staying in a family member’s spare room , and it’s 3 to 5 years at present for two bed accommodation in council/ housing partnership property. She would need to present as homeless to be rehoused faster.

Thistooshallpsss · 17/09/2026 16:03

She needs to visit citizens advice and find out about making a homelessness application at the same time you need to give her written notice to leave so the council can see that you are not prepared to house her any longer. She is likely to be given temporary accommodation it might be a hotel council property is in high demand in many parts of the country. She should be also bidding on the council housing website as well as searching for private accommodation. Having said all that the housing situation is desperate in many places and you may have to be prepared for her to move into unsatisfactory temporary accommodation. But she needs to get the ball rolling.

Danikm151 · 17/09/2026 16:03

£100 a month is ridiculously cheap. No wonder she wants to stay!

The way council housing works is that you will need to kick her out. Until she’s actually homeless she won’t be a priority.

Silverbirchleaf · 17/09/2026 16:03

I think you have been more than fair, and you have given her plenty of time to sort things out. Going into your son’s bedroom is definitely overstepping the mark.,

What efforts has she made to find somewhere else?

I’m guessing your son is doing a-levels. You can use that as another reason for asking them to leave, saying the extra bodies living in the house, noise , visitors etc is disturbing his studies. Maybe even say that you’re turning the spare room into an office for him, and had planned to do it in the summer.

gamerchick · 17/09/2026 16:04

Anyone butting in and telling you to let her stay is immediately offering to take her in.

Get a lockable doorknob for your son so he can lock his room while he's out.

Tell her that she needs to leave and stick to it. She'll never go if you back down.

GooseCreekandtheRiver · 17/09/2026 16:05

Get a lock for your son’s room.
Give your sister a letter setting out the timescale so she can use it to prove homelessness and get a council property.

Mischance · 17/09/2026 16:05

Set to and research alternative housing yourself. It does not have to be council. Find a list of private rentals and details of available benefits, then present it to her.

If she is waiting for council property you will be waiting forever. Simply not realistic.

I finished up with my elderly FIL at my place (he was sent to us by my SIL who lied and told us he was dying! - he wasn't). after a few weeks of dealing with the dreadful atmosphere with he and my OH barely communicating, I set to and organised suitable sheltered accommodation for him myself.

She is not going to leave - it is down to you to make this happen.

OriginalSkang · 17/09/2026 16:06

I think you need to start seeing what she is doing to find somewhere else

Also I don't think its fair enough for her to invite guests over at all. She is a guest herself!

30DegreesHighAndRising · 17/09/2026 16:07

What the others said, plus £100 a month for food and lodging? She will never want to move out.
You have to make her feel uncomfortable, whether that's increasing her payment, stopping her having friends over, or something else.

Write a letter for the council saying that she's homeless now and must be out at the end of this month.
Also, why are you subsidising her financially?

Imdonehere · 17/09/2026 16:07

I'm wondering what she has been doing to find accommodation? And how much she is saving for deposit/bond etc?

Whatever, yanbu. It's your home. It sounds as though she would stay permanently if you didn't push back.

DisforDarkChocolate · 17/09/2026 16:08

Even if you'd agreed to have her stay till Christmas her behaviour would mean your were justified in asking her to leave early.

Set that date and stick with it because she always going to have an excuse.

DearlyDiego · 17/09/2026 16:09

People are on the council housing lists for YEARS. She needs to get looking for a private rental.

Echoing other PP, £100 per month for two peoples' food & lodging is wild - of course she doesn't want to leave!

TFImBackIn · 17/09/2026 16:10

I would really hate that, particularly her inviting people there. I'd clamp down on that immediately. By charging her £100 you think you're being kind but you're making her think you're a walkover. Does she work? Why does she think she'll get a council place when everyone knows they're really difficult to get?

rainbowstardrops · 17/09/2026 16:17

As others have said, the council won’t even consider her unless she’s actually homeless. She’d probably be put into temporary accommodation for a good while but it’s a roof over her head.
Only charging her £100 a month though? Of course she doesn’t want to leave!
Also, her saying until Christmas - Christmas will come and go then it’ll be, ‘I’ll look for somewhere in the spring’ and on and on it will go.
I’d definitely be giving her a timeline because if she can afford a big tv for the spare room, why can’t she be saving a bit?
Is this an actual spare room, or a room that your daughter stays in when she’s home?

Silverbirchleaf · 17/09/2026 16:23

Giving her a letter is a good idea, and don’t let her extend the period.

That's a good point about the cost if the tv. They’re not cheap.

She’s forgotten that she’s a guest in your house, not a lodger.

I think you’re going to have to be proactive with her, and sit with her to complete council forms, look for alternative accomadation, sort out what benefits she’s entitled to etc. You can bet your bottom dollar that she’s done none of this so far.

AnneLovesGilbert · 17/09/2026 16:35

Oh dear, no good deed and all that. She’s treating you and your son very badly and taking the piss. No more visitors, she can go to theirs or meet them for coffee. No taking yours or your sons stuff ffs! Cheeky mare. Why does she think the council will help her? Does she work? Where’s your nephew’s dad?

Thundertoast · 17/09/2026 16:41

I dont really understand why there was ever a discussion of 6 weeks if she's looking for a council property - people wait years for them! and she won't be a priority because she's currently housed, i wouldnt expect you to know that but she should surely???

wildnwilde · 17/09/2026 16:44

Being homeless sadly may be the only way she gain Local authority housing . So as hard as it sounds you may e doing her massive favour . If she's adamant t about no to that them she will ha e to privately rent either a room or flat somewhere

OriginalUsername2 · 17/09/2026 16:48

You actually need to make her homeless for her to be homed (most likely in a B&B). You can write a letter to your council saying she can’t stay after X date.

IronEverything · 17/09/2026 16:49

She's not being a respectful guest in the slightest. Stick to the deadline. Is she at least doing housework etc to make up for the fact she's paying a pittance?

saraclara · 17/09/2026 16:52

What has she actually done so far towards finding somewhere to live? Anything at all?
