AIBU to think Mum should split her estate equally between us?

It’s an inheritance one. I’m in a blended family, mum had two sets of kids with two husbands and now says she is thinking about splitting her estate according to who needs / deserves it most. AIBU to tell her not to do this, and just to make it equal , even though it’s her money

My mum had two kids, (my half brother and sister) with her first husband, then me and my brother with our dad.

My half siblings will likely inherit from their dad and step mum (they couldn’t have more kids) and they will leave a lot through lucky property decisions. Me and my full brother will inherit from our dad, who will leave a moderate amount, through frugality.

Could all change depending on care needs right but this is the staus quo now.

Mum had a conversation with me where she said she wants to divide her estate up according to her own logic rather than split it equally. She wants to leave…

Eldest half brother - a token amount. She feels like he’ll get a load from his dad and also has had his inheritance “from the state”, he lived in council housing for a while, bought cheaply under right to buy and gained a lot when it sold and had a grant to go to uni. He now has a house, and has always worked hard, and has two kids.

Half sister - mum wants to leave her a just under a third. Despite the fact she will inherit half from her dad and step mum (probably loads) mum feels this is cancelled out as she’s had a harder time of it, no uni, doesn’t own a house, or have a stable partner etc. Chose a cool, arty precarious job that means she’s had loads of fun and travel and rubbed shoulders with cool people, but is now ageing out of the profession, and is left with no prospects and no assets. I can see the logic of this, but it was her choice to pick a fun but precarious life and she has had A LOT of fun, if you know what I mean.

My brother - a third. Had to pay fees for uni, prioritised lots of extra study so has prestigious but medium paying job, no wife, kids or property:

Me - a third, I paid the biggest uni fees and have got a good career, but haven’t been able to afford extra study to peruse a more passionate route, as costs went up and loans down. I’ve got two kids, a partner and we own a house. Mum has mumbled about possibly leaving me less as I have a partner, but hasn’t changed her mind about his now we have kids, as they obviously cost a lot.

Obviously mum will do what she wants, but I told her in my view she should just leave her money equally, even though I’d get more if she gave eldest step brother a smaller portion. It’s not fair to penalise elder brother for growing up at a time when the state and circumstances were easier, especially when he has worked hard and half sister, who had the same easier circumstances has lived like the grasshopper who sang all summer, but would still inherit.

I told her if she does this, she will essentially be leaving eldest brother or whichever siblings she decides has already had enough windfalls, with a final act that makes them feel less loved, and that will doubtless completely fuck up our sibling relationships after she is gone.

Her money - her choice - what you think is irrelevant.

her money , her will .

PullTheBricksDown · 01/06/2026 09:32

You've told her now. Back off after this and say it's up to her. Best to assume no one will get anything what with possible care costs these days. Also it's amazing how often people expect the one who 'doesn't need help' to be the one who cares for them when it's needed.

BeeCucumber · 01/06/2026 09:32

You know the answer. Her money. Her choice. Not your place to get involved.

Yet another poster worrying about their potential inheritance! But the first reply sums it up perfectly.

SereneFinch · 01/06/2026 09:34

I think you’re right to give her that advice but now you’ve done that, nothing else you can do and leave her to it

I’m not worrying about my inheritance, I’m actually worrying about my eldest half brother being effectively disinherited and getting the message that mum doesn’t love him as much

LindorDoubleChoc · 01/06/2026 09:34

I agree with you. As someone in a family of 5 children, only 3 of whom are going to inherit from my Dad, I completely agree.

Ignore the first unhelpful comment as that is clearly not what you are asking. You know what a will is. You can have an opinion on it though!

Ipsevenenabibas · 01/06/2026 09:34

You are right in that ideally she should split it equally and it's refreshing to read given that means you'll get less if she does so.

You are also right that it's her money to do with as she pleases.

I would be grateful to have such a fair sister.

2chocolateoranges · 01/06/2026 09:35

Her money and her choice.

my mum hasn’t split her will fairly due to my sibling being an addict and all money they receive will just get drank , my mum also says that she has already bailed that sibling out on numerous occasions and has had their fair share of her money.

it does leave me in a situation after but that’s her decision and it’s all legally signed .

Ipsevenenabibas · 01/06/2026 09:36

The only thing I can add which as I can see given the update is, if you can afford to and want to you could always share your inheritance with your brother. I think you're a lovely sister to be concerned about him. God bless you.

So you give him part of your money, if you feel that strongly about it.

YourKonstantine · 01/06/2026 09:39

Ultimately you have no say in it but I do agree, just because circumstances change.

my husband was a high earner, I didn’t need to work, his sister has a chronic health condition and a useless husband and struggling financially. His parents have helped them a lot over the years (nothing our way because we were financially fine and didn’t need it), now my husband has lost his in (big changes in his industry), he will never earn what he was, he’s in a job earning less than a third of what he used to and I’ve gone back to work (affecting our kids etc) but no support coming our way because his sister has had it all and there’s nothing left.

To save animosity between siblings she should be equal but it’s up to her at the end of the day.

CoverLikelyZebra · 01/06/2026 09:42

Yabu. You can have your own opinions but keep them to yourself. By your logic approx 25% of the ⅓ you inherit (8.33% of the original estate) should ethically go to your eldest half-sibling - so fine, after your mum dies and you receive your inheritance, give him that amount. Your other siblings may or may not do the same but that's their business. Your mum can do what she wants, it's her money. When some of it is yours, that's when you get to choose what to do.

MidnightPatrol · 01/06/2026 09:43

Just a big F you to the eldest brother really isn’t it

You could mention that you think you brother might feel hurt or less loved because of it abd you worry about how it will impact the family relations. Then leave her to fo exactly what she wants. If you and your siblings are unhappy you can do a deed of trust and split the money evenly on her death as long as you all agree.

SalmonOnFinnCrisp · 01/06/2026 09:45

You've told her. Its all you can do.

Does eldest know?

I'm sure you meant to be helpful and supportive but your comment is completely irrelevant.

Of course OP can do this but it doesn't help her brother deal with any feelings that his mum didn't care enough about him to give him an equal share to his siblings. A will can be a final gesture of love and care or a big 'fuck-you'.

That won't stop him feeling 'less lived' by his Mum, which is the OP's main issue

I'm guessing you are someone who won't inherit or not much given this bitter and completely missing the point reply.

BoredZelda · 01/06/2026 09:37

I might tbh but these things are never about just money are they, and he would likely be too proud and too slighted to take it anyway. He will likely inherit way more from his dad than I will from mine, assuming care burdens hit all equally, so it wouldn’t be a case of financial need.

It’s more that if she effectively disinherits him, or any of us, the emotional fall out will be massive, it’s effectively your mother saying you’re less worthy. We will be the family after she is gone, and if her last act splinters it, that isn’t worth any additional inheritance I might gain.

That wouldn't change the feeling that his mum didn't love him as much as the others though, would it?

Equal is definitely the way to go, but I don't think that you can do anything more than give her your opinion and hope she takes on board the potential hurt it might cause.

WizdomE · 01/06/2026 10:01

Your mum is basing her decision on what she knows now, but fortunes can change very quickly…. Encourage her to leave it equally as doing anything different can cause grief, discontent and a perception of favourites. Things that can happen in a family include sudden ill health (strokes), divorce, crime, job loss and you can never bank on getting an inheritance people change their minds. So making a decision based on what she sees today is folly. My mum wanted to reduce my brothers inheritance as she considered him ‘rich’, but I asked her to keep it equal which she has done…. he has recently had a stroke and is now unemployed, my other brother who struggles financially is likely to get two large inheritances, but even if he does he’ll burn through the money!!! So ask her not to judge and the future is an unknown. Leave it equally.

Stompythedinosaur · 01/06/2026 10:02

I think you're right raise that cutting one sibling out and splitting equally between the others is very hurtful.

fiveturds · 01/06/2026 10:10

She needs to understand she can’t use her will do dish out some perceived version of social justice. For the quite simple reason that she cannot see into the future. And that you cannot assess someone’s finances based on what you see in front of you. There might me a millionaire walking around with holes in their clothes and there might be someone with a smart house, car, clothes etc with it all on mortgage/finance and credit cards.

of course the other factor she needs to consider is causing a major fall out and sibling relationships irreversibly destroyed.
