Is my sisters accident my fault?

No she's being ridiculous. She should have been watching where she was going. She would be lucky to get someone willing to take the case on

Yes you could be right.

I'm 76 and recently I fell over backwards in my garden, banged my head, hurt my elbow and my coccyx hurt like hell for a couple of weeks. Can I sue because of the hole I caught my heel in? The one left when I, a few minutes earlier, had removed an enormous weed from the lawn? Not everything is a lawsuit!

If she takes that to court they will laugh at her

Go no contact @Babybirdmum she sounds like a utter bitch.

Have you got liability insurance on your house insurance?

I'd keep quite. Say you already apologised and just let it drop. If she actually did try to come after you for damages I presume that's going to cost her and be a lot of effort.

If she was a friend you would be justified in saying she was batshit and putting miles between you. I'd never have her on my property again, for her own benefit to protect you her and tell her so. It's not worth the risk.

I think it stems from the introduction of No Win, No Fee, there are a lot of lawyers who benefit handsomely from it.

Why does she even want an apology. How bizarre. I’m sorry you tripped and hurt yourself, but demanding an apology and more as though you did something. She wasn’t watching and tripped and fell. Why would it be any different in a public place? If you tripped over a chair leg that was just sat in a normal position, it would still not be the restaurant at fault. How ridiculous and irrational.

I'm not even sure that if she wasn't taking care in a restaurant and tripped over something that she would be successful in suing them. People have to start taking personal responsibility for their own stupidity.

Is your sister always a drama queen??
Tell her to get a grip. She fell over a toy and hurt herself, as do hundreds of people every day.

No do not offer to pay for dental treatment, outrageous suggestion.

She could have easily tripped over a rock or a stick. Who is she going to sue then? A tree?

It's unfortunate she was injured but it was an accident, i.e. nobody's fault. Though, if anyone were to blame it would be your sister for not looking where she was going. She must have been aware there were toys in the garden beforehand. She obviously knows you have a child!

We took our dog to an enclosed dog field recently. As I was videoing the dog doing dog things I was walking backwards and next thing I knew I was flat on my back having tripped over a weight holding down the end of a tunnel! Presumably I put a hand out to try to stop myself because I sprained my wrist. Imagine if I'd suggested the owners were at fault for having agility equipment in an area specifically designed for dogs to exercise in!

Do your mum and sister have form for scapegoating you?

When did it become the norm to not take personal responsibility? I hate this attitude that everything that happens is always someone else's fault.

I can't believe you called a ambulance. No wonder the health service is on its knees

Why? She wasn't looking where she was going. Why should OP fuel this dysfunction by paying?

OP, look after yourself and give them a wide berth.

If she needs dental treatment then offer to pay her for it, especially if she's hurt. Otherwise maybe keep your head down, hopefully she'll get over it once the pain fades.

If this happened to me at my sisters house we’d be laughing at how clumsy I was! It’s an accident. Why wasn’t she looking where she was going? You did all you could. Say sorry again and move on. Don’t beat yourself up.

You both need to dial it back down again.

Is she a lot younger than you? Sounds like it.

She had an accident and is feeling crap. You said it looks awful after reading up about it.
You took excellent care of her when it happened, but she was in shock and so that hasn't really registered with her.

Then the phone call. I don't blame you for being upset at her reaction, saying things about lawyers. It was unfair, but to play devil's advocate, she's probably crying and looking at her messed up face ( which will look worse in a few days when the bruising comes out) sorting out her dental bill etc and feeling very miserable.

Cut her some slack and let her get over the shock and the post-accident depression, and then both try to get over the argument. She clearly wasn't herself and when she upset you - neither were you because the accident was probably a shock for you too.

I don't think your Mum has been particularly helpful but it sounds like she was dealing with someone who was throwing a tantrum.

Do you owe her an apology? No. It was an accident. But it would be nice to say you are sorry she was hurt. If you want to maintain the higher ground, get in touch to say it was a terrible accident, must have hurt, how's she feeling etc. If your mum says it would go down well, visit with some chocs/flowers. She probably just wants to be made a fuss of. She doesn't remember your compassion at the time and is probably looking for some sympathy, why not give it to her? At least you can say "Well, I tried." This is probably more pandering than would be necessary in normal times, but she has had a nasty fall.

If that doesn't work and she's still talking lawyers, let her. You didn't do anything wrong and it would be difficult for her to sue. It's probably just bluster. It sounds like you two have a difficult relationship and it might be good to take a bit of a step back for a while and let things cool down. But at least you can say "Well, I tried."

This.

Her wanting compensation is just as ridiculous as you calling an ambulance for a broken nose

Your mum was there, and you still called an ambulance?!!! Why???!

Definitely not, sending flowers could be deemed that you accept you were in the wrong, which you’re not.
Perhaps you should send her a bill for replacement or repair, for any damage to the toy, as she was careless and not looking where she was going. Then I would go NC, no family is better than family like her (or your dm).

Do you not have Public Liability Insurance on your home insurance?
If she has had a hospital admission and has hospital notes/evidence of pain/shock then claim on that.
