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.

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

The OP is actually advocating that she will get LESS money as she feels her half-brother is getting the crappy end of the stick.

Unpopular opinion on mn but I don’t think people should tell their kids what they intend to do with their money.

I would disagree about this. Finding out the money will be unevenly split before your parent dies is better than afterwards. And I say that as a girl who grew up on a farm and so when my DF died my sister and I each got <£10K, one of my brothers got a 3 bed house and the other brother got a million pound farm. We all knew the one who was working in the family business would get the farm from when we were children. My will splits everything evenly between my DC so I do disagree with parents splitting things unevenly but I'm not going to fall out with my brothers because my parents have old-fashioned views.

WaltzingWaters · 01/06/2026 14:02

Yes, it should 100% be equally split.
yes, of course “her money, her choice”. But it’s really hurtful to treat children (no matter the age) differently.

cakeisallyouneed · 01/06/2026 10:13

The her money, her choice comments really wind me up. Of course this is true, it will never not be true. But two things can be true at the same time. What’s also true is that people use wills to punish or make a point. They are then not alive to see the ramifications, some of which echo down generations. If you think your mum will listen then you can warn her but once it’s your money you could give some to your DB and see if your other siblings want to do the same. Whilst that doesn’t erase the hurt, it retains sibling relationships.

This x1000000
Not around to see the fall out
We have this in our family at the moment. What MIL doesn't understand is that her choice will drive a wedge between her children. She's aided and abetted by the one she thinks she's 'looking after' - in reality, what he really needs, and she should be trying to facilitate, is all of her children feeling they were treated equally and in loving contact for the rest of THEIR lives and supporting each other in all ways. Instead, she's memorialising her favourite child and their relationship.

MarmaladeorJam · 01/06/2026 13:57

But - actually the fairest thing is equal split and each does what they will with it.

One might thrive in their 20s and struggle with unemployment/ill health/death/divorce, any number of things, in their 50s? Or continue to thrive.

An equal split is a bet on life behaving as it does - unpredictably.

Superscientist · 01/06/2026 13:53

There can be a difference between equally and fairly. It would be equal to give all children the same share, it would be fair to give them portions to put them all on the same footing as one another or related to other support they have had or what support they might need in the future.
The issues with that is a person's needs might change over time.

I'm one of 3, technically I have one full and one half sibling but we have been brought up in one family with my father very much being dad to my half sister. 5 years ago sister 1 (half sister) was a single mum rebuilding her life after leaving an abusive husband, sister 2 was climbing the career ladder and has a long term partner, no plans for children, I was in a good job, as was my partner and we had just had a child together. Flash forward to now, sister 1 has moved up the career ladder and is more financially secure than she has ever been, sister 2 has took a significant paycut to escape a toxic workplace that were trying to manage her out of the position, I've been made redundant, had a second child and currently too unwell with an unidentified illness and unable to work although our lifestyle can be fully covered by my partners income.

5 years ago my parents could have shifted their will to favour sister 1, then sister 2 then myself but now it would be fairer to do sister 2 then myself then sister 1. As it currently is both of my parents wills have everything split equally three ways

I would caution my parents that situations can change, no inheritance is a guarantee and if she doesn't explain her reasoning to the child with a token amount they may feel hard done by but having given my thoughts once and once only I would stay quiet and accept what ever they decided was best in their eyes.

By the seems of it you’re only wanting her to go equal because she wants you to have less. It’s her money and 100% her choice! Leave her alone.

Reread my post. If she leaves it unequally I will have more money but a splintered family, if she leaves it equally I will have less money but a chance at harmony

People who do the least always end up with the most.

Tessa92 · 01/06/2026 13:33

IMO should always be split equally between siblings - no decisions to be made!
My dad left his money to be split equally between the 3 of us. I was the executor and was absolutely scrupulous is splitting it 3 equal ways - even going as far as splitting odd bits of cash/change I found ‘hidden’ around the house that way. Didn’t want any disputes.

krustykittens · 01/06/2026 13:30

You are 100 per cent right and I wish more people would think of the family fall out they are bequeathing to their children when they try to make things 'fair'. Whether they like or not, the inheritance people leave in their wills signals to their loved ones how important they were and how loved they were. Getting less than his sibling is going to be a kick in the teeth for your eldest brother, whatever your mother's reasons might be. Good families will sort out fairness between them. When my PILs died, my Dh gave a share of his inheritance to his brother as he had shouldered the physical and financial responsibility of caring for them in his old age. Unequal inheritances, unless one sibling has received a lot of financial help that the others did not, is a poisoned chalice.

I can understand your feelings on this. I had a colleague this happened to. The mother left her estate to the 2 sons and excluded the 2 daughters. The daughters were the ones she spent lots of time with, they took her shopping on holiday etc. her sons less so due to their work commitments. She told no one and it upset all 4 of them when the will was read. No explanation and that I think was the hardest for them all as they had no idea why she did it. The daughters were so hurt and questioned everything. The sons felt so guilty and it put a barrier between them all as the sisters thought they knew. Was a sad time for them all

They could have just varied the will for about £500 and just split it evenly 4 ways.

Anonyhouse · 01/06/2026 13:25

I agree with you op. I think you’re right to point out the potential fall out this could cause. I see where your mum is coming from, but it’s not just money she’ll be leaving as her legacy, it’s a family with relationships that matter. I’m sure 25% would help all of you out in one way or another and not cause feelings to be hurt.

Maray1967 · 01/06/2026 13:24

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.

Agreed. And there’s nothing to stop you and your siblings from drawing down from any bequest that you eventually get and ensuring that he gets a quarter. You can’t force your siblings to do this, but it would be a nice thing to do if a parent cuts out one of their DC for a bizarre reason.

Bookloveruk · 01/06/2026 13:20

MsFrumble · 01/06/2026 12:24

Well she has told me, so there’s no escaping that.

As someone else has said on here though, if she does this she is throwing an emotional hand grenade from beyond the grave.

She’s our mother. If she’s going to do something that she thinks is right, but that will probably cause turmoil, and that could fracture the left behind family, she should at least explain her reasoning behind it.

Anjipanji04 · 01/06/2026 13:16

Nothing to do with you. My brother inherited everything from my parents who both died last year. 1.6 million he got, me not a penny.

StarlingTheConqueror · 01/06/2026 13:11

BoredZelda · 01/06/2026 09:37

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

That’s not about the money.
Thats about the message the mum will the half brother = I don’t love you as much as the other 3.

Don’t underestimate how much this hurt, especially as the lerson isn’t there anymore to iron it out.
The OP giving up a lot of her inheritance for him won’t change that.

LlynTegid · 01/06/2026 13:09

Her choice. I am glad you have had the opportunity to discuss it with your mother, and also that your mother is thinking about a will.

sunnybaros · 01/06/2026 13:08

I don't think it's about the actual amount of money which may be inherited, it's about feeling that you were left out because you made your own way in life, without being bailed out. That will be very hurtful and could cause rifts.

As an example, my BIL thinks his brother should not inherit anything as he works shifts so has a good wage and a nice home. Whereas he has spent his income on sports cars and now has to live with his mum. An odd logic.

My family and siblings though, and we all have to live with the emotional fallout of her will

I get that but its not your doing or your choice.

I agree with you OP, I had to have a difficult conversation with my mum when she knew she was dying, she wanted to put stipulations to her will, not the amount, but the way and circumstances under which it would be paid out to three siblings, drip feed it slowly to one sibling while the others got their upfront.

I just advised her that it wouldn't matter one jot to her when she was gone, but it would cause problems with the people left behind, I was to be the executor (three of us, but I knew I would be the one doing everything), and I would bear the brunt of the dissatisfaction for years to come if they had to come cap in hand, and I had to drip feed them money as and when they needed it.

At a time where we needed to pull together as a family unit, it would 100% cause a rift, I think she thought she was doing the best thing for our sibling, and she 100% was, but just hadn't considered the bad feeling it would cause between us, so she decided against it in the end.

You have done the right thing advising her, which is all you can do at this point.

fabstraction · 01/06/2026 12:57

YANBU, for all the reasons you've stated. When it comes up again, I'd continue to explain why this could be a very bad idea for the stability of the family after her death. Beyond that, there's nothing you can do except prepare emotionally and be ready to do your best to mitigate the damage, if she doesn't split things equally. Suggesting the letters you mentioned would be a good idea. She needs to at least attempt an explanation of her reasoning.

Just saying 'her money, her choice' isn't helpful in these cases. There's no estrangement, so no obvious, predictable reason to make this particular choice. Many choices are bad choices with the potential to ruin lives and relationships. Furthermore, when you confide in someone about this type of thing, you have to be prepared that they may express an opinion, especially if your choice will affect them personally. There's nothing wrong with being honest with a parent when you disagree with how they're planning to allocate whatever they leave behind.

frenchvanillacoffee · 01/06/2026 12:55

you are absolutely right and it’s admirable that you are thinking like this. You can talk to your mum (and I think you should try again) and hopefully she’ll realise that splitting equally is the right thing to do.

my sister is a millionaire and she used to get upset when my mum gave me birthday money but didn’t give to her. Token £40 or so. (Receiving as grown adult!) Used to drive me mad that my sister would get annoyed but now I realise that perhaps she saw it as a sign that she wasn’t loved as much.

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

I read an article once that has stayed with me, by Daisy Goodwin. It was about how hurt she felt after her mother died and left less to her than her siblings because she didn't need it as much. She described how it was hard not to feel, against the reasonableness of it, that her DM did not love her as much. She put in a plea to parents to treat all their children equally under their will.
