Lending a flat

I wonder what you all think of this. This is I’m afraid the first-worldest of first world problems, however it is causing me upset and causing tension within my family, so I’d be genuinely grateful to know if I’m completely in the wrong. (I also saw a similar story about a borrowed house on here yesterday so it’s well timed.)

A couple of years ago, after the sale of part of a business (said evasively so I’m not immediately identifiable) I bought a flat in London. It’s quite small but it’s in a nice part and very central. I bought I guess as dream-come-true thing, so I could go down at weekends for shows and shopping. I also use it occasionally when in London for work, and I’ve always made it clear to my friends and family that they can use it pretty much when they want, and many do which gives me a lot of pleasure.

A few weeks back my DMIL had ‘booked’ it for a weekend, and a few days before the trip she called me quite agitated asking me to drop off the keys. I said “I’m seeing you later in the week before you go, I’ll pass them over then”, but she kept insisting she wanted them in plenty of time. She is a bit sneaky in many ways and I smelled a rat, so then I said (untruthfully, but I wanted to put her on the spot) “Actually I’m going to be in London on Friday, I’ll see you at the flat.”

Long story short, it turned out she’d decided not to go down, so had told a friend of her precious eldest child that he could borrow the flat that weekend. This friend is someone I don’t particularly like or trust and wouldn’t have considered close enough to lend my flat to.

I’ve been told I’m being “selfish” and “rude”, and that I’ve “let him down and left him with nowhere to stay”. DMIL also said that the flat was hers for the weekend so she assumed she could do as she wished with it, and doesn’t see the problem.

In anger I said: “You obviously didn’t think it was fine because you lied about it.” I also said “I said you could borrow it, I didn’t sell you a **ing timeshare you could pass on.” I shouldn’t have sworn but I feel she’s been dishonest and incredibly presumptuous. I don’t feel I’ve let this person down as I never promised them anything.

Am I being unreasonable?

Where is your husband in all this??

SnappyPenguin · 04/10/2026 15:14

I wouldnt let her use it again. Ever.

Tulipsayes · 04/10/2026 15:15

Did you really need to swear at her?

Tulipsayes · 04/10/2026 15:15

How did you find out about the friend planning to stay (but who hasnt actually?)

No, I didn’t. But I’m telling the story as truthfully as I can.

She is a twat and a CF of the highest order and you should never lend her your flat again!

Yes, she's burned her bridges there. Untrustworthy wagon.

ClovisWrites · 04/10/2026 15:15

No, I didn’t. But I’m telling the story as truthfully as I can.

So how did you find out?
and where the heck is your husband in all this?

Tulipsayes · 04/10/2026 15:16

As it stands - no one has stayed in the flat.

The Op has found out the mil had a plan to allow it. How did you find out?

This.
And i fail to see why he husband is relevant. It's her flat and she's clearly capable of sorting her own sh×t out

She admitted it when I put her on the spot about meeting her at the flat with the keys.

My wife says yes it’s cheeky, but just let them have it to avoid tension.

What made you have suspicions?

your wife isn’t too bothered? It’s half her flat

I think OP bought the flat on her own.

Yes but married so…

HettyTagliatelli · 04/10/2026 15:21

Now you know that you can no longer trust your MIL, so she no longer gets to use your flat. I’d extend that to the rest of your in laws as they obviously didn’t see a problem with deceiving you either.

murasaki · 04/10/2026 15:21

I suspect he was going to stay there longer than the weekend, hence her needing the keys early. So doubly duplicitous.

agreed and in this instance it's got nothing to do with DH if, as implied, the flat belongs to OP.

OP, you probably shouldn't have sworn, but I probably would have done.

She is totally out of order.

Also, not sure how your insurance would be if it's been effectively "sub let" for want of a better description.

Smallbrowndog · 04/10/2026 15:23

I think your wife is in the wrong here - though I imagine wanting to avoid listening to her mum rant about your behaviour.

MIL is total CF, she knows she was in the wrong, and could have apologised rather than digging in.

On a totally unrelated note, I'm a great friend, and if you lent me your flat, I promise I'd never advertise it as an AirBandB during 'my' weekend.

RVectensian · 04/10/2026 15:26

Tulip is being more than a little obtuse here tbh.

Yanbu OP. Even married couples have their own possessions and are allowed to decide what happens to them.

Swearing doesn't lessen your 'correctness' or invalidate your point.

Elieza · 04/10/2026 15:27

yeah thats well dodgy and disrespectful. i’d have been really angry too. no way i’d be letting her back in. she’d have burned her bridges with me.

however i would expect my wife (ie her own child) to kick up a stink.

with cheeky fuckers you give an inch they take a mile. so if you allowed this she would do it again. next time it could be that “friend” and her two mates. one of whom drunkenly burns the carpet with a fag and spews in your bed. the other one of whom brings a one night stand guy back. that robs you.

so you've done the right thing. the mil is a cheeky lying manipulative chancer.

this purchase happened a couple of years so

Op - how long have you been married?

it is very very likely that the wife would have an interest in this flat in the event of a divorce

ByHeartyHiker · 04/10/2026 15:28

100% YANBU. MIL had no right to offer the use of a property she doesn't own. I'd change the locks as wouldn't put it past her to have had copies made (I know she was desperate to get hold of your key but perhaps that was to ensure no "surprise" entrance from you)

Tulipsayes · 04/10/2026 15:28

What made you suspicious @ClovisWrites ?

murasaki · 04/10/2026 15:29

Clearly the insistence on getting the keys early and not meeting the OP at the flat. Clanging alarm bells.

PactusCat · 04/10/2026 15:30

100% YANBU - especially if she hasn’t even the good grace to be apologetic when found out.
