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

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?

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.

Why would you agree to that? 🤯

Madness.

Oh gosh I feel sorry for you. I’ve ended up like this with my partner. I don’t love him but he has nowhere to go. It takes someone really strong to make them leave. I do think you should stick to the end of October deadline because I genuinely think she will stay forever if you don’t. It’s hard but anyone with a 6 year old child wouldn’t be without a roof over their head surely? She needs to start talking to the council. She may need for you to tell them she can’t stay.

Simply because I am not prepared to watch my nephew to continue to have no education , no social interaction and my brother struggle to feed him.

Sometimes these things just have to be done and you have to step up, DH agrees with me. There is the welfare of a child at stake and I’m not a completely heartless bitch. Although we don’t have spare money we are fortunate to have a big house and can set it up so we all have as much privacy as possible and will do our best to keep routine for DD that I hope will keep her on as even a keel as possible.

Thankfully others are rallying around and I am hoping it won’t be too long before they are sorted. There was an offer of a house before we could get them back and we are hoping another may come up from the same source. If that happens he won’t need a deposit but I need a plan B. Someone else is sorting a car amd guaranteeing the monthly payments, another has sent money to keep them fed till they get here, a neighbour has a bit of school uniform for nephew and one donated a desk for his homework, another friend has said to let me know if there is anything she can do and offered a fold out bed. It is so lovely to see and taking some of the stress off, I slept last night in relief.

If that is madness then so be it and if you would be prepared to ignore a significant child welfare situation in your family then shame on you. This is distracting from the OP’s thread so let’s leave it there and my apologies to the OP for the hijack.

YABU because it’s impossible to find places to live atm. Council housing does not really exist. In my town 4000 are waiting to be housed with only 485 having been housed last year.

Likewise, private renting is impossible if you have a child under 10. Landlords have 20 people vying for every house. You know what they do? They choose the one single person from that cohort. They don’t even want couples.

This is because demand is outstripping supply. So they can.

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.

No they wouldn’t be housed with the council. Not in my town, anyway. Even people with disabled children are low priority where I live.

However, what you should do is to tell her in no uncertain terms that your sister stops inviting people around and stays out of your son’s room. Get him a lock.

Therealjudgejudy · 21/09/2026 08:01

She is taking advantage of you.

She must be saving a ton of money off the back of your kindness.

Give her notice and prioritise your son.

LouiseK93 · 21/09/2026 14:32

Well OP should kick her out so sister is unintentionally homeless then sister can approach local council and apply for emergency housing.

It doesn't work like that either. Or anyone who wants to leave somewhere and get housed by the council could just stay with family for a bit and get 'kicked out'. Housing officers know all the tricks and they would look at her circumstances before moving with her sister and make a judgement based on the whole picture.

Your son must come first.
