Stepchild wants to see finances and money spent on his stepsiblings.

Greenhairedmonstor · 10/08/2026 12:45

My late FiL who I never met, left school at 15, fell into the right crowd while he was doing a labouring job and ended up with a little empire.

There is something in place that is not quite a trust. It allows SiL to choose to live frugally without working, and has enabled my husband and his brothers an income which supplements their incomes.

Their children will benefit after their parents’ deaths when whatever is in place will be dissolved.

My husband has his own business as well.

My stepchild is 18 and will go to university next month. I also have another stepchild who is 13.

The eldest has asked that now that they are an adult that they want to look at my husband’s finances. Essentially they want an account of any money that is spent on my children and they wanted my husband’s estate to be reimbursed from my share of the house when he dies.

Now Mumsnet always asks, no I was not the other woman, my ex meets more than his share of his financial responsibilities and I also work and rent out a house that I own in my home country that I will eventually return to. Husband’s ex is comfortable and I don’t believe this has come from her.

Inevitably my husband subsidises our life.

This has been a bitter blow to my husband and he doesn’t see how his relationship with his child(ren) will recover.

If one of my DC came to me and said that I'd be tempted to remove them from my will. Entitled sod. I don't think I actually would but I would be reminding them they're not entitled to any of my money and there is no chance I will be giving them details on my finances.

It sounds like this is an ongoing issue. OP’s previous post about a wedding from earlier this year gives more context: https://www.mumsnet.com/talk/am_i_being_unreasonable/5509580-wedding-aftermath?page=1

At the wedding (which OP’s children weren’t originally invited to, until her husband requested they be added) stepson was asked to move away from his family to another table to accommodate one of OP’s children and it sounds like OP’s child was showing off about the skiing holiday to stepson’s wider family. Stepson made the “spending our inheritance” comment then and his Mum got in touch with OP’s DH later to back him up. OP’s sister in law (who I assume is stepson’s aunt) was apparently sarcastic and didn’t want to sit at the table with OP’s son.

Personally I don’t think this is actually just about money, I think stepson, his Mum and his aunt feel OP’s children are being favoured by her DH over stepson and his sibling. Whether or not they actually are, OP’s DH needs to speak to his children and try to get to the bottom of why the stepson feels like that and how they can improve their relationship. Once he’s dealt with the emotional side he can then addresses the inappropriateness of the request to go through his finances.

Personally I don’t think this is actually just about money

It's never just about money.

I would just say sorry son, you don't seem to undertsand how it works. Our money is our money and we'll spend it how we like. You don't get any say in it and we're not accountable to your for it. I am not sure what gave you the idea your were.

We inherited money from FiL, not you. And we'll decide how it will be split among the children, if there's anything left.

Now you go and build a fabulous future for yourself where you don't have to think about our money. We know you can do it.

this.

the step son sounds very entitled, jealous and bitter. Could probably do with some psychotherapy earlier than later to sort his issues out.

But i would be very much, our money is ours to spend as we wish. We aren’t planning on dying any time soon, so stop ruining family moments by focussing on inheritance

The assets that generate an income, a quarter of which my husband benefits from, will be sold on the death of my husband and siblings. My stepchildren will inherit a quarter of the assets between them- the rest going to their cousins.

He also has an income from his business.

I think on the surface your stepson is being wildly unreasonable.

However, i do think there may be some mitigation depending on the terms of the Trust- if it is a family trust that includes him, he might not be totally unreasonable to want to see how the trust is currently being managed. Does your have a legal right, under the terms of the trust, to see how the trust is being managed?

Though I cannot see how he can ask for access to how your DH spends his income, whatever the circumstances of the trust. That is a fairly gobsmacking over-reach.

Does he have concerns that your children are benefitting significantly, at his (and his sibling’s) expense? I.e. is your DH spending significantly more supporting your children than he ever did on his own two children? Has your DH invested more time in your children than his own? I’m just wondering if it is all simply awful behaviour on your step-sons part, or whether this is actually an expression of brewing resentment, built up over years (even if a wholly unreasonable way to express it).

Supersimkin7 · 10/08/2026 23:21

OP, SS may have a point. probably not the one he’s making, but a bigger one.

First Marriage Children get shat on in wills. SS might be worried that his GF’s legacy is heading/already at your DC.

This happens too much, and it’s hideous - not only has FMC got no present dad, his/her heritage has been swiped too.

Would FIL want that? Nope. He left the £ to his relations, not another woman’s unrelated DC.

I’d explain to DS that the assets will be maintained out of their income by DH, and he’s not in any danger of losing his inheritance.

Your DC are entitled to O, incidentally. Except - depending on FIL’s wording - what DH gives them from his own income, which does seem fair.

If you think that’s unfair, welcome to the world of entailment and trusts. Keeping it to blood family and swerving complications with blended households is what they’re there for.

Is this for real? This grossly entitled teenager has totally unreasonable expectations, how could he think for a moment that it's right to spout this nonsense? A clue is that dad thinks asserting proper boundaries will cause their relationship to fail. Has this entitled brat been subject to boundaries before? Does he know what one looks like?

The correct response to these demands is 'you are having a laugh, mind your own business'. Certainly don't dignify this entitled, divisive money-grabbing by pandering to his grubby fantasies.

This sums up the situation perfectly.

Absolutely do not pander to his gross attempts at manipulation. It's not his business. End of.

Sugarnspicenallthingsnaice · 10/08/2026 23:33

Teenagers can say some stupid shit. They're like giant hairy smelly toddlers - they have all sort of notions about life that they haven't got the frontal lobes to think through. Hasn't your husband realised this yet?

I'm astonished he didn't just reply with something along the lines of 'are you fucking mad?' and leave it there.

All this handwringing!

(ETA: I understand hurt feelings in the moment, but he really does need to learn to shrug it off, it won't be the last time all these kids you're raising make some ill-considered statement that crushes your souls a little.)

Idontknownowwhat · 10/08/2026 23:44

Im shocked that an 18 year old feels they have the right to ask this.
Your husband is in a hard spot because saying what he should say will do nothing but inflame the situation.

What a horrible situation, how did SS become this way?

It's absolutely wild tbh. Imagine being this grabby, greedy, entitled and tone deaf at 18. Wow.

He has no entitlement of any kind at all to his dad's money. And will lose any inheritance his dad kindly wants to leave him if he cuts off his own nose to spite his face.

This is precisely what should be said to him, in a message. Then he should be absolutely ignored until he starts behaving and replying decently again.

Lonulum · 11/08/2026 00:26

I would assume its about uni.
He maybe being expected to confirm parents money and his own. But anyhow it seems crazy he may need a loan if his dad is receiving all this money. Has he not saved to pay for the fees and living costs?

Has he not savwd money into his kids accounts for uni costs

openended · 11/08/2026 00:38

You have presented this as coming out of the blue however the resentment your step children feel was apparent in the post you did about the wedding. You cannot be blind to that. Dss may well need income details from his dad towards his uni living loan which is fair enough. Nobody is owed an inheritance. If the grandfather left it so the money went to his own grandchildren then fair enough but if he left it to his son then it is up to him to decide what to do with it. You've stated those assets will go to his children and if tat is all set out and protected then there shouldn't be an issue.

What dss doesn't get to do is dictate how his dad spends money he earns and if it was my child I would be telling them that. Your dh needs to be firm in telling his children that he loves them but they don't get yo dictate to him how he manages his own income.

My aunty came over and took my daughter to a show. When she was telling her step-sibling about it the immediate question was who had paid

I'm confused - this is your aunty and your daughter, so what does it have to do with his bitterness about his father's finances?

Because he saw his step-sister getting something nice and his immediate thought that his dad must have paid for it.

As hard as I try to cut him some slack, I keep coming back to him being greedy, selfish and resentful

Katey83 · 11/08/2026 01:02

he is 18 and acting as a jumped up little dick with an overblown sense of entitlement - but that’s 18 year olds to some extent. It is for your DH to explain that DSS is not owed a living by his father, by you, by his grandfather’s estate or otherwise. I don’t see this as a relationship ending conversation/situation with a young adult child to be honest / there often need to be frank discussions about finances.

Katey83 · 11/08/2026 01:09

also / inheritance and stepchildren is a tough one. My DH came into our relationship with very little and has hugely benefitted from my income and existing assets, similarly I have befitted from his inheritance (many years into our marriage) - I think it is fair to divide our shared assets and wealth that exist in the marriage (cash, family home, property etc) equally between our joint children and my stepchildren and that things belonging entirely to me (such as copyright over my works - I make a living as an artist) go solely to my children.

ThisTealViewer · 11/08/2026 01:54

Asking to inspect personal finances and demand reimbursements from an estate feels quite overstepping, especially right before starting university.

Delilah26 · 11/08/2026 02:03

He definitely needs to be put back in his place. I have to wonder what sort of vile behaviour he generally shows for the husband to be worried about "backlash" and being "terrified" of the result that might come from telling the cheeky little fucker - who "bitterly resents" his father spending his own money as he chooses - to back off and mind his own business.

Caniweartheseones · 11/08/2026 02:06

This maybe isn’t about the money. Your SS sounds very resentful and may feel cast aside in some way.
Your DH should find a way to broach this subject. Your SS is still young and may need validation about perceived slights and some healing before a being told that he needs to have more respect for his loving father and forebears before presuming to inherit anything.

Fleurdavril · 11/08/2026 02:39

Extraordinary that an 18-year old has the audacity to demand to go over his father's and step-mother's finances. To demand reimbursement from the stepmother to the 'estate' is outrageous.

He is already thinking ahead to the death of his father and stepmother - at which time he wants some of the proceeds from the house to go into 'his' inheritance as 'compensation' for what he perceives as 'his' money being spent on OP and her children by his (perceived) overly generous father.

It sounds as though he has possibly been put up to this. Plus, he is carrying massive resentment towards his step-siblings and OP. This resentment has led to this nitpicking accounting of his father's spending.

It's for his father to take him aside (even take him alone out to lunch or dinner perhaps) and sort out the facts with him. Fearing backlash is a nox̌nstarter - this son is being supported at uni and by the sound of things, he's dependent on his father to some extent. Father needs to bite the bullet and OP should back out

Explain:
a) son has No rights to father's financial information - it's private

b) how father spends his income is up to father, not son; there will be no
reimbursement from OP's share of house or in any other way

c) the assets left to the four siblings are inviolable - the siblings receive income from the assets but cannot touch the assets; these assets are not affected by father's day to day spending of his cash income

d) the assets will eventually be sold off and then GFs descendants will get equal shares

e) the shared house of OP and husband will... explain the intentions eg house will be occupied until death of both OP and father, sold and proceeds split accordingly, no 'reimbursements' to the 'estate'

f) father loves his sons, supports them fully, but at the same time is going to continue to show care and support to his stepchildren

g) father has a partner and they as a couple decide on arrangements, with consideration of all four children in mind; no further discussion is to be had about finances

OP needs to ensure her children are not antagonising the stepchildren and fueling resentment

Angelyogini · 11/08/2026 06:01

Well I get op's point. She massively benefits from husband's estate/income and from the sound of it from previous posts so do her own children.
DSS would also upset me if he inquired as to why he is left out/undercut by his dad's spending and he threatened me getting less.

Calliopespa · 10/08/2026 22:45

I wasn't actually claiming he did, rather that the fact that what is or isn't mandated by law isn't necessarily coterminous with what is or isn't pretty crappy behaviour.

And in answer to your question about the imbalance between what is and isn't said to SFs and SMs, the difference I think is that men tend - not all, but very generally - to move on and forget to defend the interests of their own dc whereas SMs are more about defending their own at the expense of sdc.

From my time on MN I find that women tend to always prioritise their own children in a way that men don’t seem to. And there does seem to be some hypocrisy on MN around this where women are told to keep their assets.

I think what happened to SS at wedding was awful - he was asked to move seats away from from his own father & aunt at his uncle’s wedding. This was to accommodate his 9 year old SS who wasn’t originally invited. Then his step-brother arrives at his table and announces that his dad has paid for his ski trip. Why couldn’t the kids just have stayed with their dad?

How exactly is a 17 year old supposed to feel about his dad playing happy families and funding other children?

And I think he has a point about the inheritance income. FIL presumably meant his money to go to his own family.

And as someone else said it’s never just about money. It’s often also about what it represents.

ProudCat · 10/08/2026 21:28

Yeah, as above. I'd say the kid is confused. He possibly doesn't understand how a 3 year marriage trumps his 18 years as this man's child.

There's also the slightly weird thing of why not show him the finances? If the guy isn't prioritising someone else's family over his own then it's not a problem. The outrage at being asked by a naive kid seems somewhat disproportionate.

"He possibly doesn't understand how a 3 year marriage trumps his 18 years as this man's child."

It doesn't, but that does not mean that the DH cannot spend any money at all on his second family which is what the DSS is looking to achieve.

.

"There's also the slightly weird thing of why not show him the finances?"

I'm sorry, but what???

If anything, the father sharing with the son exactly what he spends his money on and having to account for how much is not spent on the child, his full brother or his mother is really quite bizarre.

I would never dream of asking my parents to show me their finances to check what they are spending their money on.

Likewise if my own DC demanded to know what I was spending my money on then they would not be told.

Another2Cats · 11/08/2026 06:32

ThatCyanCat · 10/08/2026 21:35

I wondered that. It's totally crazy. As several PPs have said, this is not the kind of thing the average 18 year old comes up with, which makes me think there must be something going on; OP denies the son is being put up to it by his mother (how would she know?) but even if not, there's obviously something complex going on here. Even if it is the worst possible reason and he really is just entirely driven by wanting as much inheritance as possible, it still doesn't justify people baying for this teenager's blood like this. It's deranged. He is motivated, at worst, by being very young and concerned for his inheritance as his father has remarried. What is motivating the much older adults who can't fling enough shit at this kid they don't know?

"What is motivating the much older adults who can't fling enough shit at this kid they don't know?"

I think it may be because he is demanding that a parent account for how they spend their own money and also demanding that any money that is not spent on him or his sibling is accounted for and reimbursed to him at the time of the parents death.

I certainly wouldn't use some of the language used here, but if a child of mine tried to do that to me then I would very definitely think much less of them.

There is huge, huge 'mumsnet spite' towards children of first families who are supposed to suck up unfair treatment at the hands of one, or both, of their parents, who put their all into new relationships. Posts where a new family inherits everything leaving first children with nothing at all are not uncommon. The OPs DH would do well here to reflect more broadly on his actions and behaviours before declaring his relationship with his children destroyed. It seems unlikely this has come out of the blue, even if crass and unpleasant
