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.

InWithPeaceOutWithStress

I don’t know why you are confused. I talk about my children and how my ex meets his financial obligations. My SS is concerned when my husband spends money on them as he feels his and his sibling’s inheritance from their father will be diminished. This is separate to money generated from their grandfather.

This conflict is of course deeply upsetting to my husband who doesn’t want it to escalate. He can’t just tell his own child to mind their own business without some sort of backlash.

I think your husband can and should tell his child to mind their own business. The asset left to the grandchildren is intact (presumably appreciating in value) and the income generated is your husband's to spend as he pleases which could include investing it and bequeathing it to whoever he likes or spending it on cars and cocaine. I would explain this to the SS and tell him he will have no further information about your husband's financial affairs because it really isn't any of his business.

Your SS seems very entitled and greedy which means he's unlikely to flounce if he thinks he might lose inheritance from your husbands assets. It's hurtful to your husband but if he doesn't make a stand now he could find himself having to explain to his child about every penny he spends for the rest of his life. His son is young so hopefully he will mature but right now he seems like an obnoxious little shit.

Pinkflamingo10 · 10/08/2026 15:17

There is more going on here. I don’t think it’s as straightforward as calling SS a CF.
he obviously resents his fathers new wife and her children. Specifically all of the attention and money they receive from his father. Which he presumably he feels should be for him and his brother alone. This has been festering for a while I would say.
he is going to uni now and wants to know where he stands financially- does he have money to self finance uni entirely, can he buy a flat or does he need to rent, does a need a student loan etc

UnbeatenMum · 10/08/2026 15:20

18yo is being staggeringly rude. He needs to understand that your husband can do whatever he likes with his money, both in life and in death if you're in England.

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 is exactky wht I would say to the entitled 18y old. He needs a reality check.

Sparkletastic · 10/08/2026 15:26

It’s coming from a place of jealousy and insecurity. Your DH needs to have a calm conversation with his son.

Joliefolie · 10/08/2026 15:02

The OP said in April that she and her ex had been struggling to pay for an overseas school trip for her 11 yo DS, so DH paid for it. 17 yo DSS commented to the 11 yo that he was spending his inheritance. I imagine that is the extent of DSS' financial, legal and moral reasoning.

This convinced me that there’s a third party in play - 17 year old don’t talk about someone spending their inheritance. That’s some very odd phrasing that’s come from someone else.

‘Stepson wants to see finances and money spent on siblings’

I want to see the Great Wall of china and take a trip to the moon…

…there is a lot in life that we may want but wanting something doesn’t necessarily mean we can actually have it!

his dad needs to tell him that his spending is ab absolutely none of his business and to wind his little entitled neck back in.

TheOnlyWayIsIlford · 10/08/2026 15:29

OP - It sounds as if jealousy and bitterness about money being used to support your children has been going on for a while. (theatre tix incident et al)

This is an emotional issue, not just financial grabbinesss and your DH could have addressed it with his Dc earlier. But now is the time. to talk to them about their role in his life , will always support them, will not be leaving all his assets to you and your kids, yes, there may be a certain amount of mix and match about how the two of you spend money - but if he wasn't settled with you maybe he would be squandering all his cash on Porsches and gambling.

Has their Mum got a new partner?

Have you ever 'treated' them? Gone out for a meal as a family and they've seen you pay for their share? Bought them a birthday / Xmas present just from you / your dc? Given them a helping hand towards getting kitted out for Uni? (taken them to Ikea, bought them a wok?) i.e do they have any idea that the money flows in different directions, not just from their dad to you and yours?

What is your relationship with them like?

If your husband isn’t siphoning off money, he should not have any trouble showing all interested parties copies of the accounts. The best way to handle these things is without attaching emotion to them. Keep the books open and transparent. Treat it like the simple matter of accounting that it is.

I have a similar setup from my mother that constrains my father. My father chafes at the arrangement too.

The Son hasn’t asked for details of the accounts for the asset. Those could indeed be open and transparent.

He's asked for his Dad’s personal spending. Which is not generally something people share with others.

ThatCyanCat · 10/08/2026 15:32

saraclara · 10/08/2026 15:17

OP has made it clear that it's the latter. This kid is clearly entirely selfish and irrational. If his dad comes down hard, he might well decide to go LC/NC with his dad, even though he's the one in the wrong. And his dad will be heartbroken.

No, I don't think she has been clear, or at least not explicit. There's talk of conflict and all that but I haven't seen anywhere where she's said the teenager has actually threatened to cut ties if this isn't done.

On a side point, I really dislike all the abusive name calling of an 18 year old from various posters.

Calliopespa · 10/08/2026 15:32

Chenecinquantecinq · 10/08/2026 13:14

I don’t think this is the case. Potentially the grandchildren have inherited with the children having a lifetime interest. Very different scenario.

I think that is what it sounds like.

And it is hard to know with only the vague description of "like a trust but not a trust" but if it is a trust, the terms of the deed and the settlor's intentions will be decisive.

And even if the father is a beneficiary, that can come with strings attached as to what the funds are intended for.

The boy isn't wrong that his Grandfather's intentions should be honoured - and it isn't a stretch to think the terms don't provide for step-children to benefit.

People are quick to call someone a spoilt brat - especially if they are a "trustafarian - but I actually think it would be as bad for him to see his grandfather's arrangement not being honoured correctly.

But is impossible to say anything decisively without more detail.

lessglittermoremud · 10/08/2026 15:36

It sounds like for some reason your step child believes that you are with his Dad for money. I can’t imagine why else he would be asking who paid for show tickets, school trips etc
Your DH needs to explain to his DC that they have no entitlement to any money from the trust fund until he himself passes away.
Any financial information isn’t anyone else’s business until then, when the assets are sold and the proceeds split between all the children.
Whilst your DH Ex may not be ‘egging’ her child on, I do wonder what the narrative is from her…
I have a step Mother and Step siblings, I have no idea how they work finances in my Fathers household.. ie if he contributes to her kids/grandkids or if they only fund their own families presents etc
It’s none of my business and I can’t imagine why a child would feel so entitled as to ask to go through a parents finances whilst they have capacity etc
By being with your DH you may have nicer holidays etc then you would have alone etc but surely that’s the same in any marriage, one person does usually have more income/asset's especially second time around.
I don’t think it has to be the end of their relationship, your DH just needs to be honest
“Fred, i’m not sure why you feel entitled to my financial information, on my death the trust fund will be dissolved and the proceeds split between you and your sibling and your cousins.
Your Step Mum has property etc of her own which are also none of your concern , and how we work our finances is no ones business except ours.
If you are concerned about how you are going to manage at uni, shall we sit down and do a spreadsheet together so we can list your income, grants, allowance and what your expenditures will be because I’m concerned that you’re feeling under financial pressure”

@Greenhairedmonstor I just looked back at your April thread that a PP referee to and you mention that your DH’s ex wife specifically said to him that she feels any money spent on your children is money taken away from her children.

She is the source of this resentment your SS is feeling.

Your DH needs to have a conversation - probably several - with his son explaining that day to day income and spending is not his inheritance.

OP's husband cannot siphon money from his father's legacy to the grandchildren. The legacy is a protected asset which generates income. The asset was left to FIL's grandchildren and the income to his children. OP's husband is spending his income and inheritance not his child's.

Greenhairedmonstor · 10/08/2026 13:22

My children are 10 and 12, there are no joint children, nor will there be, I am 47. We have been married for three years.

It is not a trust as such. My husband cannot deplete any assets. He can however, use any money generated as he sees fit.

My husband paid for a school trip for my son which my son spoke openly about, with gratitude.

My stepchildren have all of their needs and wants met .

My younger stepchild stays often and both of them see their father alone without us intruding.

My husband is devastated, elder stepchild seems very bitter.

You say you have an income from a rental (do you work?) and that your dc have a father, so why did your Dh pay for your child’s ski trip? I can understand your dss feeling resentful therefore. Presumably your Dh is supporting him financially to got to uni and he has no right to ask to see his dad’s finances, that is outrageous. This whole ‘end of the relationship’ is overly dramatic, but your dss sounds very resentful of money being spent on your dc, but that’s your DH’s choice. Would he object to money being spent on anything your Dh buys?

I'm not certain (without further detail) that that is in fact the case.

To me it sounds as though the grandchildren are in fact the primary beneficiaries and the father has an annuity.

Well the DSS is a grabby little scrote isn’t he? How disgusting. Your poor DH must be so ashamed.

Agreed he is being awful.

LancashireButterPie · 10/08/2026 15:44

Wow, my kids are all in their 20s and I can't imagine them ever asking to see our finances.
What arrogance.

WitcheryDivine · 10/08/2026 15:44

It sounds to me like the 18 year old has a poor understanding of the situation. Am I right @Greenhairedmonstor that essentially there’s an asset that will eventually be sold off and the grandchildren will benefit, and in the meanwhile there’s some income from the asset/business which goes to your husband and his siblings?

If I’m right then the only way that stepson has any potential of getting hold of that income is if his dad chooses to save it and then leaves it to him. If that’s the case I think dad needs to patiently explain that and also explain that yes he sometimes spends money on your kids, but most of it goes on ordinary living expenses and of course a lot on his own children. If he wasn’t married to you he might be spending that money on another girlfriend, or lots of expensive dates, a football seaso ticket, or taking a belated gap year or in fact whatever he likes. Your stepson needs to be disabused of the idea that his dad’s money is his while his dad is still alive.

I can’t help wondering if your stepson spends too much time online and has absorbed misogynistic ideas about women using men for their money.

BaronessEllarawrosaurus · 10/08/2026 12:55

I'm reading this as the grandchildren were left the estate but the children have a lifetime interest in it. If that's the case then your SS possibly has the right to see how the estate itself is being managed but still wouldn't have the right to the financial breakdown of how his father spends the money he does have.

There are two different things going on here.

As Baroness says, if there are assets held in some sort of trust with the children having a lifetime interest and it then passing to the grandchildren after the death of the children, then the grandchildren can ask the Trustees about the trust itself.

Are the children also the Trustees of the trust or are the Trustees separate? Eg maybe solicitors?

So DSS can ask the Trustees about what assets are held by the trust and what distributions have taken place to the children.

.

However, what he is not entitled to in any way at all is:

"... 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."

What happens to the money once the Trust has given it to an individual child is purely down to that child - they can spend the money how they like.

A son demanding that his father account for money he spent on his second family and for that then to be reclaimed from the second wife is really just totally bizarre.

ilovemybluesharpie · 10/08/2026 15:45

The 18yo is an entitled brat and your DH needs to shut him down immediately. "No son, I will not be discussing my finances with you now or ever, do not ask again. It is my money and I could leave it all to the local cats home if I wanted to, I could blow it all on back to back cruises if I wanted to, basically I can do what I want with it and it is none of your business".

It probably is driven by his mother, who resents money spent on your DC, and she has instilled this into him.

BillieWiper · 10/08/2026 15:50

TheNinkyNonkyIsATardis · 10/08/2026 14:22

I disagree in part. Not that he's necessarily entitled to the money, but that he's not entitled to an explanation.

Entitled is perhaps the wrong word, but I think that a bit of simple transparency about how inherited finances work in a family where there are a lot of assets coming is no bad thing.

I have received significant lump sums from inherited shared family property, and now I need to work out from scratch the best way to manage them because "nobody talks about finances".

Don't get me wrong, part of that conversation can be, "how I spend my income from this is none of your business", but a bit of a chat about how it works is surely a good idea?

I do know what you mean to an extent. But demanding to know exactly how much money someone has spent on their own children is way way beyond reasonable.

Nobody has the right to access another person's private financial information or start some kind of amateur forensic accounting mission in order to establish if they feel they've been given 'what they deserve'.

And turning 18 makes someone an adult legally but not emotionally. It certainly doesn't make them financially responsible. Or entitled to know how someone else chooses to spend their money.

Could you imagine demanding one of your parents handed over their bank accounts and statements from the last two decades simply because you happened to have turned 18?!

No they don’t have all of their needs and wants met. I can guarantee you that like most children what they really want is for their mum and dad to live together and be a family.

So when your DH does something nice for your children it hurts because that is time/money/attention that they feel should be theirs. It doesn’t actually matter if they have £100000 a year spent on them inside they are still a little kid who is worried that dad loves someone else better.

I personally think your DH should talk to him and explain all about the trust and the money involved in it. After all isn’t it a parent’s responsibility to teach their kids about finance.

Calliopespa · 10/08/2026 15:51

Iheartlibrarians · 10/08/2026 14:36

Oof, this thread is quite the ride. I think:

  1. The stepchild (I don't think you've said which sex, but I'm going to go with the majority and assume male, because otherwise it's confusing) is still very young. He's more than likely to grow out of this, but does need the firm but fair explanation others have suggested about why he is not entitled to audit his father's spending.
  2. No, he shouldn't be told to fuck off or deprived of any inheritance his father does control. That is not how good parents deal with their children, even when said children are being idiots.
  3. Being a child of a "first family" (as I am) can lead to insecurity- it probably wouldn't hurt to think about why he might feel this way and what further reassurance, support and maybe just attention your DH could provide, would it OP?
  4. That said, it is absolutely for your DH to resolve it- not you. If you get involved, you are accepting the premise that it's his business.
  5. I think people are over-reacting to your comment about whether their relationship can recover- you're clearly not talking about DH abandoning him.
  6. At the same time, your DH is over-reacting too- if entitled 18-year-old behaviour were insurmountable, wouldn't most of us be estranged from our parents?! I'd be telling DH to calm down and remember he's the actual grown-up.
  7. You've said repeatedly that you don't think your stepchild's mother is behind it- not sure why several PPs have missed this. Cherchez la femme, I suppose.
  8. Maybe a mad idea, but is there any role he could be given in looking after the assets? Might make him feel he's got some input and actually give him something to focus on that isn't sniping at what your kids get? Obviously if it's overseas bank accounts rather than rental properties here, not so much.
  1. Being a child of a "first family" (as I am) can lead to insecurity- it probably wouldn't hurt to think about why he might feel this way and what further reassurance, support and maybe just attention your DH could provide, would it OP?
Especially when it seems the money has been provided by the DSS's grandfather, who clearly had an intention to pass his estate down to the grandchildren's generation. He needs - and is right to ask for - reassurance that that intention is being properly honoured.
muddyford · 10/08/2026 15:55

I'm 63 and wouldn't dream of asking my DF about his finances. DSis has an idea as she helped with the inheritance ISA when DM died, but we would never discuss it.
