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.

You are a kind and caring sister and daughter, and also clear sighted. That is probably why your mom is discussing her plans with you.

Very hurt feelings are guaranteed if there is no explanation to your brother while she is still alive. Probably also big impact to sibling relationships.

And advance conversation will still hurt your brothers feelings but will give him time to process his feelings and not be blindsided by this at time of inheritance.

Our family has history of unequal inheritance distribution. In one case, it was explained many years ago, and it was accepted by all, there certainly was an unfairness to it, but no surprises. So no big impact to sibling relationships.

In my own little family it will be an equal split, even though the earning potential is vastly different.

I would stress the impact to sibling relationships, and the need for heart to heart discussion in advance if she decides to do an unequal split.

I do think she is being rather heartless to inflict this hurt on her oldest son. Does she even care about the hurt she will cause to him? Or she just can’t see it why it will hurt?

Family left behind argue and fall out whether or not money is involved. In many ways it's good when no money is left except enough for a funeral.

MsFrumble · 01/06/2026 09:34

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 agree with you.

Wills can destroy families.

In our case, it was a ruthless division, all very clear and no exceptions. They really simplified things. As such, it went smoothly.

Most people I know who had to divide and choose etc - there were dreadful conflicts.

And I do not agree with the Mumsnet mantra - "their money their choice."

chirrupybird · 01/06/2026 12:42

How much money is it? If it's not a lot just splitting it equally would keep everyone happy. If it's life changing amounts and she is worried about some of her children each according to needs seems sensible. Her decision anyway.

Reallyoldperson · 01/06/2026 12:43

My dad left nothing to my brother and me or his grandchildren from his marriage to my mum. Everything was left to his second wife and then to his son by that marriage and those grandchildren. I wasn’t annoyed for me or my brother, but upset for the grandchildren not to even get a small token amount to acknowledge them. Even £50 would have been better than being ignored.

Of course it's 'their money, their choice'.
Whether people agree with 'their choice', is another matter.

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.

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.

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.

SandyHappy · 01/06/2026 13:01

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.

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.

Morepositivemum · 01/06/2026 12:14

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

I agree. There is no "should" about it, Its the testator's choice.

godmum56 · 01/06/2026 13:05

MsFrumble · 01/06/2026 12:12

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.

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.

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.

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.

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.

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

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.

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.

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

CallOfDemons · 01/06/2026 13:30

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.

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.

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.

OneTealShaker · 01/06/2026 13:38

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

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
