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?

Suggest that an immediate need for use of the room in question by another family unfortunate, will enable sis to apply to the council with some reasonable chance of success.

It always seems to be the same, when generosity gets gets abused and perceived as a measure of weakness.

An opportunity here to draw to the attention of other like minded family "generosity" to ensure that the rules are laid out professionally at the beginning of any such generosity. The "offender" is left in no doubt where they stand and encourages them to spend some time looking after themselves, instead of relying on the generosity of others to cover them.

Quadrupling the rent will serve as an incentive to get their finger out. (Family or not).

Sxwer · 18/09/2026 22:21

She is a rude, entitled cheeky fxxker.
How dare she go into your sons bedroom and think that is ok.
She left where she was and assumed she could stay with you.
Such entitlement.
Tell her to go back to her childs father and not to use your house as if its hers.

No good deed goes unpunished.
Your son is entitled to enjoyment of his home.
She could have been respectful but decided she didn't have to.
Do not allow her entitlement to drive your son out.
Give her a date and a very firm talking too.

rosagarten · 18/09/2026 22:31

One thing I do know is that she should not be going into your son's room and helping herself to his stuff (she shouldn't even be going in there at all) and she should not be entertaining friends whilst staying at your home.

QueenietheGreat · 18/09/2026 22:34

@Leopardspota
Ah yes, be as that maybe
You had a lovely time together
But your sister wasn't an assuming greedy grabby total taker using the tenuous link of blood to insert herself into your seat and not move was she?

BrumMum1978 · 17/09/2026 21:12

Our mum died a few years ago and our dad isn’t around anymore so no, there isn’t really anyone else she could stay with. She has a couple of friends but I don’t think they could have her and her son.

I hadn’t thought about going to the council with her but I think that’s probably a good idea. I’m going to ask her to show me what she’s actually applied for and what they’ve told her because at the moment I don’t really know. I don’t want to keep asking her every day what she’s done because I think we’d end up arguing but I do need to know she’s doing something.

l The £100 was meant to cover food and bills and I wasn’t trying to charge her rent. I’ll have to work out exactly what everything is costing because I honestly haven’t sat down and added it all up. The mortgage and council tax are already expensive and having two extra people here obviously adds to the food and electric.

I’m not sure I could suddenly ask her for £200 a week though, especially when we agreed £100 a month. I think I need to have the conversation about moving first rather than changing the money now. My son is saying he wants his room and privacy back and I can’t ignore that.

You agreed £100 a month. She agreed six weeks. Why should only one of you get to change your mind?!

She's a single parent working part time, if her hours are right she'll get universal credit to help towards rent costs.

ReadingSoManyThreads · 18/09/2026 22:54

By giving her until the end of October, it's already doubling the amount of time you said she could have. I honestly wouldn't tell her end of October. I'd tell her her time is up now, she's had more than 6 weeks already and she needs to have found somewhere by the end of this month.

She's either incredibly naïve regarding getting a council house OR doesn't realise you know how hard it really is. She could be on a council waiting list for years, and whilst she's living with you, she won't even be a priority. She'll only be a priority if she's homeless, and she's not whilst living with you.

Really, she should be upping her hours, working full-time and renting privately a small flat, and getting housing benefit help with that, if needed.

I'd be livid if I were you in this situation. She's taking the piss and being very entitled. I think she's stringing you along and doing nothing to find her own place.

Get her out.

grinandslothit · 18/09/2026 23:19

You and your son don't seem to like her very much

She's been there 2 months

Maybe I'm a complete mug but I had a family member sleeping on my floor for 4 months. They didn't pay me anything and they left cigarette butts on my floor that fell out of their pockets

That said, if they had been paying me a little something even 100 a month, and my place was bigger, and they didn't leave a mess I wouldn't mind let him staying longer

Nearly50omg · 18/09/2026 23:35

She can go back to the house she shared with the ex surely then??

selffellatingouroborosofhate · 18/09/2026 23:54

BrumMum1978 · 17/09/2026 19:24

Yes I think I probably was a bit naive about the council side of things. She keeps saying she’s on the housing list and that she’s waiting to hear but I don’t think she really understands how long it could take. I’ve told her she needs to find out properly what her options are rather than just waiting for a property to come up.

She left the property she was living in with her partner when they split up. As far as I know there wasn’t any DV and she could have stayed there while things were being sorted but she didn’t want to. I don’t know if that would mean she was intentionally homeless, I’m not really sure how it works.

I think she came to me because she knew I would let her and her son stay. She didn’t want to go into temporary accommodation and thought staying with family would be easier. I understand that but I also didn’t realise it would turn into this.

I’m going to tell her to speak to the council properly and find out where she stands. I don’t want her to be stuck but I also can’t have her assuming she can stay here until something comes up.

She left the property she was living in with her partner when they split up.

Was he the sole named tenant?

Seaitoverthere · 19/09/2026 00:17

No advice but sympathy. My brother is returning to the UK at the end of the month with his child and moving into one of my adult daughter’s room as she isn’t currently living at home but may be soon as her and her partner are moving more locally. I have an autistic adult DD who struggles with even her sister staying let alone an uncle who was last in the UK over 10 years ago and a cousin she has never met.

Brother hopefully has lined up some work but has no deposit. I am fully intending to write a letter to say he is homeless after a certain date so he can take it to our local homelessness prevention and see if they will help with a deposit for a private rental as they did this for a neighbour who was being evicted but I may be being overly optimistic.

So your brother hasn’t even been living in the UK and therefore paying taxes here, yet you/he expect the state to fork out for his deposit or house him? What a piss take!

ADHDspoonie · 19/09/2026 00:35

Yep, the kindest thing you can do is say she can't stay with you; it will help her with the council.

NotTheMrMenAgain · 19/09/2026 00:49

If she’s working part time in a care home then she won’t be earning much. So she should be getting Universal Credit for herself and her child, if her income is low enough then it would be over £700 per month. Then she can get additional UC to help cover renting from a private landlord - if she’s eligible for two bedrooms under local council rules then this payment (in my area) would be around £690 per month.

So you won’t be throwing them out, penniless with no chance of a roof over their heads. She’s either completely clueless/hopeless or just very comfortable at your house, with no intention of leaving.

DryadsRest · 19/09/2026 01:15

get a padlock with a number combination lock fitted on your sons door when she’s out! No need for her to use his things whilst she sorts her self out!

DryadsRest · 19/09/2026 01:17

Also she can use the money she is saving on rent to socialise outside of the house, thats fair I think

plus I would seriously consider locking your valuables away if you don’t feel able to trust her friends…..

Bogliasco · 19/09/2026 01:29

I moved to a new area near where my sibling lived. It took me 3 months from moving in to moving out. 1 month to settle the upheaval. 1 month to start looking and decide where I wanted to live. 1 month to find somewhere and be moved in. 3 months is realistic so by the end of October should be fine given she's already had 6 weeks.

She can't afford private rental because she only works part time. She needs to up her hours to full time then she can afford private rental.

There are always so many reasons people say they can't afford private rental when the truth is they could if they spent their time differently either working more hours or looking for a better paid job. Why is the council or housing association's responsibly to plug the gap in earnings?

Once he has passed the habitual residency test I expect him and his DC to be given whatever help is available to other uk citizens. My experience is limited to my neighbours I was advocating for as they are vulnerable, facing homelessness and were unable to sort themselves.

You are making assumptions about the taxes and are not correct, Not going to explain it further, I’m awake at this hour as incredibly stressed about the whole situation as will be financially supporting them with money I don’t have to start with and trying to keep my autistic DD on as even a keel as possible .

I could do without random internet keyboard warriors taking the moral high ground when I was just offering some sympathy to the OP of this thread,

hcee19 · 19/09/2026 02:05

Some people are on council waiting lists for years. She needs to fine somewhere to privately rent

DeftGoldHedgehog · 19/09/2026 02:36

Stop being such a doormat, OP.

benfoldsfivefan · 19/09/2026 05:08

Why is she only working part-time? She works in an industry where there’s a huge amount of work available all of the time, the capacity to earn over £3K a month every month.

It all sounds a mess. Give her official notice and tell her to go to the council. Leeching piss-taking relatives are very much a thing. You and your son don’t deserve this crap (is he doing exams this academic year?). He’s your priority, not her and her child and I really feel for him in this environment.

It may be changing locks time in four weeks time - stressful but she’s seeing you as her meal ticket and your son has to come first.

How many private landlords do you think a) charge rent within local housing allowance rates (clue, none, they haven't risen in about a decade) and b) are willing to take low income, universal credit claimant tenants? She doesn't have a hope.

Bulldog01 · 19/09/2026 10:41

I think you have been very generous with your sister,£100.00 a month rent is too low.She really should not be going into your 17 years old room touching gaming equipment.Inviting guests without running it by you.I would of thought that 6 weeks is not long enough to find accommodation.I know from personal experience living with family members in these situations can be very challenging.You sound like a loving caring sister, but you & your sons needs to come first.I would have a chat with your sister,set some timeline dates with boundaries,the rent needs to increased to a sensible amount £300 minimum.She will hopefully get the message & show some respect to you & your son.
Wishing you a resolution X

Etiennethemad · 19/09/2026 16:05

As she is sharing your property with you she is classed as an Exempt Occupier. There is no legal tenancy agreement.To evict her you need to give her 'reasonable notice' in writing. The end of October should be fine. If she doesn't leave then you will have to change the house locks, while she is out, and then put her possessions in a safe and secure place that she has access to. Then the council will see her as genuinely homeless.

Discodance1988 · 19/09/2026 16:45

The irony is if she was homeless with her nephew they would be housed with the council.....
You need to write her a letter telling her she has until X date and then she's homeless with her nephew, she'll be put in the top priority for council housing.

Girliefriendlikespuppies · 19/09/2026 22:44

Your sister is a CF 🤷‍♀️

£100 a month cant be covering all of her food plus the increase in bills? Plus you have lost the single person discount on the council tax?

Is your sister claiming universal credit, plus child benefit, maintainence etc? She needs to sort her finances out and move out ASAP.
