Inheritance with grandchildren and step grandchildren

I meant it a general point. If step children in general inherit a bit more because they have step families then good for them after a childhood of navigating that type of situation. I doubt it happens that much t in reality. They will be used to being othered though. It just happens in blended families .

This is total nonsense. Every single person ever born has four biological grandparents.

Whether those grandparents are alive/dead or involved/not does not mean that they do not exist.

Your brother is correct

However your sister feels about her mums Will, and you and your brothers opinions, the fact that she couldn't congratulate your brothers daughter on her A Level results is out of order - that would tell me all I needed to know about your sister, and I'd just be leaving her to stew...
Also telling was your mums comment of "noted" when you and your brother mentioned the inheritance, she sounds like shes made her decision, and whilst acknowledging what you've said, nothing will change...your sister needs to be careful - her kids inheritance may end up being distributed elsewhere!

Seems fair enough to me - it's her cash her decision.
Her step GC will (might) inherit from their mum / her parents.

OP, imo it is cruel of your mum to cause this trouble just to prevent your sister possibly using her inheritance to give a foot up to her sc.

Come on, if she’s caused a big rift between her own children was it really worth it?

Reality is that your sister will now over compensate by making sure the sc have the same advantages potentially causing further rifts and tensions between her children.

Your mum should have left as it was.

God no! But I have two sisters, and like I said my mum wanted to treat one of my sisters differently in her will.

It would have been a commentary on how she lives her life from beyond the grave, and as the executor I didn't want my mums legacy to be one of bad feeling, it was hard enough losing her young, I spoke to her and explained how it would feel for my sister, how it would be for me being the executor carrying out wishes I didn't really agree with, and she reconsidered on her own, I would have carried out her wishes either way.

People on here would have said, stop interfering, stop being grabby, entitled etc, it's her money blah blah bloody blah.. but ultimately my mum would still be dead and we'd be left with the fall out from it, with not one party being unreasonable.

Family is everything to me, and I am the one always striving to keep us together as a family after our mum died, 11 years later and we are closer now than we have ever been but it could have gone the other way.

I personally think how OPs sister treats her 4 children is how anyone else in the family should treat her children, engineering something to purposely go against that would not sit right with me as a sibling.. I would never EVER say 'not my problem', if it's a them problem, it's a me problem.

Your sister is being absolutely ridiculous.
the stepchildren will inherit from their mums family also so they’ll be well looked after. And they’re not being left out, they’re just inheriting less.
I have stepchildren and it wouldn’t even cross my parents mind to include them in their will, nor would I want them
too. They’ve enough coming from their mum eventually.

Agree !! inheriting a bit more is an advantage that slightly makes up for not having been brought up by both parents in the same household.

Doesn't this mean the step-kids inherit twice? Once from their natural parents and then from their step-granny? That hardly seems fair.

No, it’s respecting her mother’s right to make her own decisions, and not co-signing her sister’s demanding and entitled behavior.

That the sister feels aggrieved does not mean the mother has done anything wrong at all. She hasn’t.

We don’t want to get involved and have said it’s her money and her decision.

I would never do this to my sister, it's basically the same as "I'm alright jack".

The least I would have done is have a word with my mum and tell her designing the will to ensure less value was placed on two of her children was always going to be problematic in their family, and if it made a difference you would be happy for them to get a 9th share instead. You don't have to ask her to change anything to just give your simple opinion on it (assuming you felt that way). I would have then gone back to my sister and a told her what I thought and what I had said, but ultimately it's your mums decision to make and you don't think anything you say will make a difference.

As it stands you have done nothing, and are not going to voice an opinion on it to your mum either, even if you feel a certain way, which you do.

I could never do nothing when it involved my sister and her children, even if ultimately I thought whatever I did would make no difference, I'd at least be empathetic about how they felt at a bare minimum.. not just shrug and say 'not my problem'.

My DS won’t inherit from my DH’s mum, and I wouldn’t really think it would be right for him to. She already has a load of biological grandchildren.

I asked my DM if she would skip me in her will actually, and leave my inheritance to my DS as I would rather he benefited, and she said no. She wanted to leave her assets to her children.

They all agree that granny should do what she wants with her money and can see that she doesn’t know the step children as well.

That's a little distasteful. The children are being dragged into an adult discussion and justifying it. I'm sure they are all agreed, seeing as they benefit. A little empathy would be nice to exhibit.

My parents had it written into their will that my sd should not receive anything. It all goes to my children if I die first so this clause was necessary. My sd has her own family to inherit from, she’s a part of my family but I don’t expect my parents to treat her the same as their four grandchildren.
ultimately it’s up to your mum and your sister is behaving badly

Are your sisters biological children going to inherit anything from their step-siblings grandparents? Presumably not. So unless your sister is also asking the other step-grandparents to include her (non-biologically related to them) children in their will then she's being unreasonable and is actually creating a situation that is treating the children in her family unit unequally, even more so if it were evenly split. The step children will get something which is generous of your mother, and then when the step siblings inherit from their own grandparents and her biological children do not she will have to explain that.

Regardless, no one is entitled to be left anything at all and should just be grateful for whatever they do get.

Well yes, one time things can happen. It’s a completely different situation though. This is about step DGC. They are nothing like adopted DGC.

Actually it seems sensible to me.
We don't know the ages involved but if, as the mum says, her children are financially secure then it makes sense to skip a generation. This is why it's a good idea to give your adult children money when they are younger, when it's more use to them.
An alternative to what the mother has done would be to split it between her own offspring and they could vary the will to pass it on to their children.

I fully understand why she wouldn't want to leave her money to some unrelated children.

I have seen threads where grandparents don’t treat adopted children the same as biological children especially when it comes to money

Adopted children are the same as biological children, why does someone always seem to think this is a gotcha on these threads? Adoption makes them your legal children.

SDC are not the same as either of these.
