Unbalanced Inheritance Division

Stilson · 15/09/2026 09:26

I'll keep it brief, my parents both died some time ago, and I can't get over this.

The estate was split with 20% going to me and 80% to my sister. She gets £160k I get £40k.

Both about the same age, both been a part of the family equally, she is wealthier than me by a large margin.

I want to cut all ties as she refuses to balance out the amounts, even a 60:40 split.

We're it the other way round I would be uncomfortable with the settlements and would rectify it, she won't.

AIBU?

But OP hasn't said her sister is/was a favourite child. Instead she's said there is no reason she can think of why her parents would do an unequal split in their will.

but the will is literally saying sister is the favourite child!

Unless, possibly, there's a debt to pay back which is the only thing I can think of.

Gymnopedie · 15/09/2026 11:52

Is (was) your sister the golden child and you were the scapegoat, always coming second?

theneighbourgotmycake · 15/09/2026 11:47

Is it possible your sister lent them money, and loads of it, and they are repaying their debts that way?

They should be honest about it, but that would be an explanation.

That is a good suggestion.

My Dad re did his Will when he was very ill and completely bollocksed it up. Missed Mum out altogether and left everything to Dsis and i. His brother (executor) tried to read it but Dad wouldn’t let him.

as soon as we read it when he died we immediately told him to ignore it all and transfer everything straight to Mum, because we’re not greedy bastards

Scottishskifun · 15/09/2026 11:49

Is there a discrepancy between your life set ups e.g. your sister is MW job and your well off? That could be a reason that your parents decided she needed more financial support.

I know my mum has a discrepancy set out in her will because my brother has had significant financial assistance and lived with her rent free for 8 years whilst I have been financially independent since 18. She decided to balance it out in her will but crucially I told her she had to explain this way in advance so I wouldnt be the one dealing with the fall out which she has done.

Luddite26 · 15/09/2026 11:49

I can understand your position. Yanbu if you want to cut ties. Do you not get on apart from this
It was a very devisive thing to do. Do you know why they did it.
Did they tell you.
I was left out of father's will 1 sis got £5000 1 dB got £50000 1old flame got £5000😂 the youngest daughter got the rest. Which was a lot. He had enough to leave my kids something instead of me but he chose not to.
Hey ho. You can't do much about it but it is hurtful.
You have to move on. So if you generally get on with dsis stay friends if this is on top of everything let her get on with her life and you get on with yours.💐

That is so awful, as a parent I cannot comprehend people who behave like that, and have a favourite child.
Anyone would be absolutely crushed.

Wanting to cut your sister is understandable. She doesn't have to do anything of course, but if she doesn't care about you, why would you stick with her.

If you spend the next decades resenting her and being obvious you are furious or upset, it's never going to be a happy relationship anyway.

Unless there are very severe medical needs and the siblings would end up paying anyway because someone cannot be independent for medical reason, it's never acceptable to have favourites with your children. It's sad.

joelcreasey · 15/09/2026 11:48

My partner was in a similar situation and there were no signs at all, it was completely out of the blue.

similar happened in my family as someone was cut out for marrying the wrong class of person (!), we did a variation and made it equal.

its so tough as it’s a last act and it feels like a division/distribution of love.

Having sat and listened, for what felt like days, to my parents tortuous discussions about their will I'm sure there will have originally been some reason why they came up with that split. But it may well be so convoluted that no one could understand it except them. Number of visits over many many years, random amounts gifted for DIY, money paid out for weddings are some examples. However it would be easy for your sister to even things up and she hasn't. If you don't want to speak to her anymore I think that's perfectly understandable.

She may not have been aware until the will.

Edited

Unless your parents were fantastic actors and masters of subterfuge you'd know if they favoured your sibling over you long before the will came out!!!

chirrupybird · 15/09/2026 11:41

It sounds very odd if there were no problems in the family relationship. Have you asked the solicitor if any reasons were given? How long ago was the will made? You can challenge a will, but I'm not sure that an unfair split would be enough, but you could ask. Often if a person wants to exclude a close relative from inheriting they write a note in the will to explain why, to stop them having much room for appeal. If you challenge the will your sister may consider a fairer split rather than it going to court.

Golden child scenario very often starts in childhood before addiction or personality issues really apply.

Sister may have been an easier child or prettier or better at ballet or whatever.

Golden child is often quite random from an external pov.

That may well be true, but OP says there is no reason she knows of. If her parents favoured her sibling she'd have an inkling before it got this far.

Neuronimo · 15/09/2026 11:36

Not sure if this has been covered. Did she care for your parents more, when they were aging and unwell. This happened to my MIL and sister and they never got over the rift. I am sorry OP I can understand why you are so hurt.

Aluna · 15/09/2026 11:33

GasPanic · 15/09/2026 11:19

If so why not just say that then ?

She may not have been aware until the will.

Aluna · 15/09/2026 11:32

Additup · 15/09/2026 11:06

She may well be, but ime there's usually a reason why parents favour 1 child over another (eg personality clashes, addiction etc).
Not that I'm saying these reasons are the case here obviously.

There are no further details that would add light on the decision. No extra children, no money being lent, no personal problems , health or otherwise. To all intense purposes we should have been treated exactly the same.

As I say were the situation reversed I would make the split fairer.

You must know better than us why your Mum chose to do this.Difficult to comment on the fairness unless any possible reason is known.

TishHope · 15/09/2026 11:27

Similar thing happened in my family, think a gender inequality. First of all, understand that there is nothing you can say or do in this situation that will change the outcome.

I went nc with my sibling. It was pretty mutual actually. I won't know when he dies. Nice one, mum and dad.

hangingplant742 · 15/09/2026 11:25

Depends if you were bad to your parent or not. In their eyes, not yours.

Hoppinggreen · 15/09/2026 11:22

So you want your sister to give you money or you will cut her Off?
Nice

GasPanic · 15/09/2026 11:19

Aluna · 15/09/2026 11:02

Sister may just be the golden child.

If so why not just say that then ?

Coffeewinecake · 15/09/2026 11:09

Did you financially benefit in some not obvious way when they were alive? Perhaps during childhood? Could they have felt that they were able to spend more money on you than her and so are redressing the balance in their minds?
You may not be able to answer this or never know.

Thinkofnewthings · 15/09/2026 11:09

Xnz2022 · 15/09/2026 10:28

I'm sorry but there is something...

Perhaps you genuinely don't know what it is. Maybe your sister does...

But no one does this randomly, usually it is because they perceive some form of unfairness or injustice of wrongdoing.

This doesn’t make sense to me. Surely if people do it, it’s because they think one person is more deserving of it. Nothing to do with injustice or wrongdoing.

Bloodysquirellls · 15/09/2026 11:06

Wow, you parents are shit! So sorry. What fuckers.
