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?

I think you are being unreasonable to expect your sibling to disregard the will. It was legal and whether you understand the split or think it fair is irrelevant. If you have a good relationship with your sibling it's less unreasonable to hope that she might be generous, assuming she feels her inheritance puts her in a position where she can afford to be.

You are not being unreasonable to decide that what seems to you to be a selfish refusal to mitigate an unfair will makes it impossible for you to remain on good terms or any terms. I'd probably aim for minimal contact, rather than no contact, simply because feelings and positions can change over the years - there's little difference in practice.

Unless there are genuine reasons like addiction or illness, parents that do this are effectively saying a massive fuck you to the children recieving less. It's a horrible,nasty thing to do to leave those left dealing with the fall out 😡

But that's why so many of us are saying that there probably is a genuine reason. If the OP has gone through her whole life NOT feeling unequally treated by her parents, there must be a reason why they made this choice now. She either knows this, but hasn't put it in her posts, or she genuinely doesn't know, in which caase she needs to talk to whoever helped draft the will.

beAsensible1 · 15/09/2026 15:54

she could've lent them money, paid of debt etc. unfortunately you'll never know. Fine to cut her off though as it is incredibly hurtful and even moreso with no opportunity to find out why.

pilates · 15/09/2026 15:53

Your parents were cruel to do that.

I can’t under the logic behind it. They would have know it could cause conflict.

Longleaf · 15/09/2026 15:52

It must be very painful but sister is following parents' wishes. Whether or not she knows their reasons it will be a big decision for her to go against that. Plus the pain is in their decision, DSis sharing isn't going to change that.

AutumnLover1999 · 15/09/2026 15:47

And the sister can rectify the situation if she wanted to.

Not really... she can share the money but she can't change the fact that it's not what the parents wanted.

She could but she may also be feeling an obligation to honour the parents' wishes.

Or this could all be nonsense because we must be talking about one parent's will.

Yout anger is misplaced. Don't be angry with your sister be angry eith your parents. They created this situation.

And the sister can rectify the situation if she wanted to.

Ponderingwindow · 15/09/2026 15:42

Cutting all ties is being dramatic. You are hurt right now. Step back from the relationship. You don’t have to destroy it, just give it space.

AutumnLover1999 · 15/09/2026 15:40

That's awful. What happened?

I'm guessing they didn't get the kidney.

AutumnLover1999 · 15/09/2026 15:40

BlankSheetOrKnownQuantity · 15/09/2026 12:03

It’s a horrible feeling when this happens. I went through it my sister got everything. It was devastating. I had to have a lot of therapy to get over it.

We were NC and then 6 years afterwards her dh contacted me as they wanted me to agree to testing as she was in kidney failure and they expected me to step up and be tested !!!!

That's awful. What happened?

Stilson · 15/09/2026 10:17

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.

It’s …….‘intents and purposes’……

Longleaf · 15/09/2026 15:31

There must be a reason. Maybe you don't know what it is but they didn't wake up one morning and (both of them?) decided to leave things so unequally, for no reason. Did they have mirror will that both left this unequal split? Or are you only talking about the most recently deceased parent?

They've left your sister in a really difficult position. Maybe she knows the reason (or not) and does want to respect their wishes.

It seems odd that your answer is to cut her off? Is that something that's been coming for a while?

AutumnLover1999 · 15/09/2026 15:23

WinWhenTheyreSinging · 15/09/2026 09:37

But, in the absence of any back story, it’s a patently unfair decision which she could rectify. It would almost certainly wreck my relationship with her in the OP’s position.

Agreed. Depends if the sister values the money more than a relationship with her sister I guess. The ball is in her court to fix this. I'd be very hurt too in your shoes 😔

You have not the first idea. I was responding to OP.

Wow! why would you say that? Parents can be cruel in all sorts of ways.

When we made our wills, one of our DC was in a far better financial position than the other, but we still split the bulk 50:50. As things have moved on, they are much more equal now. I would hate to leave any of my family feeling as the OP does, because it must be really tough to never get answers from the people who caused the upset.

She's consciously being vauge. Did she has less contact with her parents, did her parents financially support her more, did her wealthier sister support her parents, etc?

My father was always a difficult character, and lived abroad for final 12 years of his life. I maintained contact, while siblings / he didnt. When he had an accident abroad I paid for treatment, siblings refused. I solely cared for him in old age.

My father, rightly or wrongly, left me slightly more in his will. I split everything equally to avoid anamosity, but siblings felt they had "right" to equal share.

Badgerandfox227 · 15/09/2026 13:01

OP I would feel the same as you, and on the face of it without a reason I would walk away from your sister as I’d not be able to overcome the unfairness. I know my sisters would balance with me if the same happened.

That being said I would give your sister one last chance to explain why. Could it be that she helped them more in older age? Did you visit them as often as she did?

Sorry you’re in this position.

I wondered about this too. There will be an unequal split between my sibling and I when the last remaining parent dies. Over the last 20 years I have given up a lot to support them when needed. My sibling has done nothing despite being in a better position to help than I am. Last parent is disgusted with them, so has expressed that in the will. I won’t be sharing what I am left.

However, I will explain this clearly if asked. In this case, if OP is in the dark, it would be kinder to share the reasons.

DewDropsAndCobWebs · 15/09/2026 15:01

Is a relationship with your sister worth more than money?
If the money is more important, end your relationship with her, and move on.

Firstly, it's very easy to hypothetically give away a large chunk of money, much harder to actually do it when it's your money. OP is basically asking her sister to give her £40K.

Secondly, I suspect there is a reason OP's parents decided to split their estate like this. I believe OP when she says she doesn't know what reason, but there must be an underlying reason (reasonable or otherwise) for her parents to have done this.

Finally, it was her parents' choice to split it that way, and it's reasonable and legal to respect those wishes.

Edited

I agree with this POV, I think.

It must be hard to be on the receiving end of this, OP. And I'm not saying I would like it or be OK with it. At the same time, your parents must have had their reasons, and I can understand why - on being asked to more evenly distribute the money - your sister is taking her stance.

At the end of the day, it's your parents right to split the money how they wished and I don't think it's fair to expect your sister to rectify that when she clearly doesn't want to. If you don't want to speak to her because of this, that's your right too.

If inheritance is going to be split unevenly, I think it's the parents responsibility to make that known - and their reasons why - beforehand, rather than this way where fall outs are inevitable.

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.

Blaming parents for your nastiness...

Your full of it. Of course there's a back story, you just want to elicit sympathy, hence not sharing.

I hope you do break contact. That'll save your poor sister from having such an ungrateful sibling!

Ouch

She’s hurt and confused, not necessarily ungrateful.

TallSturdyGirls · 15/09/2026 09:30

I'm sorry that happen to you. That would be very hurtful. Do you know why your parents chose to do this?

This!

Contain4 · 15/09/2026 14:39

I could not imagine not splitting it completely equally to save arguments after I die.

If one child was a millionaire and one was a single parent on a low income, then I wouldn’t split it equally but I’d sit them down and explain my reasons as soon as I’d changed it.
