AIBU to tell DH to split his inheritance with his half siblings?

His mother should have said in her will that her estate should be split this way. It's just nonsense saying that's what she wanted as she made no attempt to ensure that happened.

I can't imagine betraying my mother this way.

Your husband is a horrible person if he doesn't share this money with his Mum's other two children.

I’m beginning to think this is made up.
DHs mother and father died when he was in his ‘late 20s’
He discovered he was adopted by his father after they’d died.
He has 2 much older brothers.
They’ve recently said they want their ‘share’ of their mother’s estate’
Mother didn’t make a will expressing this.
OP thinks he should give them their ‘share’.
Whats happened to the ‘small flat in Kensington’?
OP hasn’t answered any of our questions and it’s her first post.

I've been in a vaguely similar situation recently. My parent died with no cash in the estate. The only thing left was a property that she and I were joint owners of, and which automatically became mine in total, when she died.
I recently sold the property and I gave my brother (who obviously didn't have an inheritance) a fair proportion of the proceeds.

I'll admit that it feels quite weird handing over such a large amount of money (though the proceeds from the house was a small fraction of OP's DH's inheritance) but there was no way I was going to see my brother empty handed, while I gained. It's made a huge difference to him and his wife and it feels really good.

So yes, I think it would be really shitty of your DH not to give a share to his step siblings.

I'd find it hard to stay with someone who would go against their mother's wishes and keep all the money for himself. It's greedy, selfish and immoral. Obviously the law says its his but could the siblings take him to court?

Morally he should. and I would be taking a good hard look at the relationship if he didn’t bearing in mind he knows his mothers wishes

i would also make sure that your wills are watertight so he can’t get his hands on your half

DH should keep 50% that came from his dad.

He should keep 33% of the half that came from his mum. It's what she wanted.

That he's prepared to lose the only living family he has (or are they not family to him because he's adopted?) over 330k - when to you 1m isn't an enormous amount - tells a person everything they need to know about your DH. His explanation of them not needing the money because xyz just confirms it.

Wicked, that he should ignore his mother's wishes just because she can. His half-siblings' reactions ought to haunt him if he goes through with his plan.

It is upto him. However, I do think he should split what was left from his mother with his siblings.
This is why you need to do paperwork and not trust anyone. Especilly if you're in a blended family.

And is there any record of what was in the DM’s estate - only the value or the original estate should be part of the claim, not that of the final estate that the DF had (who is the biological father to the DH and step father to the siblings).

"...and not my sister"

Or, more accurately in this case, the biological children of my adoptive mother who hid the fact from me that I was adopted.

Oh and presumably they’ve inherited from their Dad if they are retirement age.

Need @hesbelleth to clarify:
-how they know this was the mother’s wishea
-the time frame between DH inheriting and siblings claiming their share.

I blame the parents.
Get a Will checked by a solicitor. Update it whenever there is major life change.

So according to them their mother wanted them to have a third each of her portion of the estate. That’s about 15% each. But the parents died when your husband was young and left everything to him. So, she didn’t leave her older children anything, her husband may have been the main earner in the family, and this was done years ago. I’m afraid I think it’s a bit late for the siblings to demand anything, especially having failed to be there for him when he was young.

No, he doesn’t have to. If his mum felt that strongly, she’d have made a will.

This. I was left (nowhere near 1m) and inheritance by way if a Will. The person told me shortly before death that they wanted me to share it. I did what any honourable person would do and shared it.

He'd still be left with around 668k if he gave them their third of the mums half. He'd be a huge dick if he knows that was what his mum wanted, regardless if the dad didn't stick to it.

Yes, this - how did this bit of information come to light?
And if it is true, it was the dad’s moral obligation and his mum’s actual responsibility to ensure it happened.

It’s now DH’s money to decide what he wishes to do with it. Has time passed since the Will was executed and the news of this mum’s wishes has come to light? is it tied up somewhere and so not so easy to just hand over the siblings “share”? Will he need to sell the flat?

How do you know the mum wanted her estate split three ways?
And why is it only becoming an issue now if both DH’s parents died when he was young?

It's a very small flat in Kensington!

Or divorce him and have half for yourself?

If his mum’s will didn’t specify what happened to the money then it’s up to him to decide whether he wants the money or wants a relationship with his siblings.

Are they likely to contest the will?

What will? It seems the mother didn't make one and it's not clear whether the father did.

If the whole lot is a million, then DH should have the half million from dad and then split the other half million

Why do you think the mother's share amounted to half a million? The father might have acquired it since her death. By inheritance from his own parents, for example. His stepchildren would have no claim.

I think the problem is that after a very long marriage, both spouses trust the other to do the right thing after their death as regards to their children. So they leave mirror wills, leaving the other everything.

I know for example that it wouldnt cross my mothers mind that my father would marry again if she passed first, but personally I think that he would be very vulnerable to someone who wanted to marry him, he would be desperately lonely without her. And how often do we see it that a widow/er leaves their estate (including everything the late spouse left) to the second spouse who promptly cuts the dead persons own kids out? Seen it a lot on MN, never mind RL. Happened in my family and caused massive ructions.

Solicitors can advise that you can write a will making sure your kids get your desired share, but some people really dont want to think about the possibility that their wife/husband would screw their kids over either intentionally or otherwise. They cant bear the thought that their widow/er might marry again for example, so they assume the best and go with that.

I’m a bit shocked that he thinks as he does tbh!

Does he really think so little of his Mum’s memory that he would take all the inheritance, leaving her two other children with none?

It’s obviously the morally right thing to do to share out that half of the money between the three of them, regardless of the legal position. Yes, his Mum should have sorted it out legally in her lifetime, but I bet she never thought her husband and son would need tying down legally to do the right thing - she trusted them in other words.

That’s if he wants to follow his mums wishes, but this is a mess of his mum and dad’s making and i can also see his point that it was all his dads to leave as he wanted, which was all to your DH.
