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

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.

@Greenhairedmonstor

It would appear that somewhere along the line, your elder stepson has been given the impression that you and your children are somehow more financially favoured?

Your husband does not need to discuss his finances, in detail. It's none of his son's business.

Rather than your husband taking umbrage at this wholly unreasonable request, it is, at least, worth a chat with his son to unravel where his (the son's) misunderstanding comes from.

There is no need for your husband to distance himself just because he feels uncomfortable/angry

TigTails · 10/08/2026 14:01

Also, any chance this has been prompted by your husband’s ex?

Viperregency · 10/08/2026 14:01

Ok, look he’s 18 and being a twat, but your husband has to dial down the drama, about the relationship never recovering, or he’s devastated, it’s ridiculous

he needs to act like a grown up, and talk to his son. Explain it’s his money, he will spend it as he wishes, it is not his son’s money, he is not entitled to it. And tell him the conversation on finances ends.

but this isn’t about money. It’s about resentment over his new marriage and the time spent with your kids, so he needs to deal with this. What is his son feeling, does he feel excluded. Does he feel your kids get more of his time. What’s the real issue and address that.

and dial down the drama, it’s where his son gets it from.

Mangelwurzelfortea · 10/08/2026 14:00

It still seems that the stepson resents money being spent on the OP and her children. It's been a relatively short marriage and it does look like he sees her as a gold-digger. It's hard to say who's wrong or right about that from the thread.

OP does your husband also take his own kids on ski trips and expensive holidays? Does the resentment purely come from the fact he thinks his dad is wasting 'his' money (on the OP and her kids) or are there actual legitimate grounds for that resentment?

AprilMizzel · 10/08/2026 13:59

He supports them and SS will be supported at university.

If the step child knows how the non trust operates and knows they will be suppiorted at Unni - then tell him to wind his neck in.

If it's mentioned again in future - I'd do what PP suggest and make sure all protections are there in case he tried something in future.

But for now - DH needs to tell him to fuck off and what he's asking is none of his bussiness and move on.

If I was your husband I would write him out of the will.

Absolutely he deserves no more or less than this. At least your dh isn’t trying to defend his son’s behaviour, there’s that small blessing.

allthingsinmoderation · 10/08/2026 13:59

I really cant see why your DSS thinks he has the right to see his fathers financial details.
i would get some legal advice regarding the complicated FIL estate and send a solicitors letter to your DSS explaining his position.

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.

@Greenhairedmonstor - that was me and a few others. Sorry for misreading. But why does your DH think this needs to be the end if the relationship? That is an extreme reaction.

Same question here, he would cut off his son because his teenage (only just adult) son overstepped a bit regarding finances?
Your husband needs to reassure his son that he won't lose out, that he won't get an inheritance off his dad for many years yet and shouldn't be interfering in how his dad chooses to spend his money now.

malware · 10/08/2026 13:57

i would just tell him. Haha - that's not how it works. Our money is our money. Not your money.

Tell him to go away and make his life on the assumption he'll get nothing and then if there's anything leftover it will be a nice bonus. Tell him you both intend to live a long and healthy life, and he'll be in his 50s before he needs to think about it in any great depth.

And I would point out that talking about his inheritance is really rude because it is talking about your death and that the only thing that matters to him is money. Tell him it shows a distinct lack of love and caring his part to do so.

Boymum2104 · 10/08/2026 13:57

Expecting to look through your parents finances is wild

Dery · 10/08/2026 13:56

“I'm going to hazard a guess that those making posts like this are only thinking this way because OP is from another country.”

@saraclara - for me, it has nothing to do with OP being from another country. The same applies to much of my extended family. And why suggest that anyone taking another view is doing it out of bigotry?

For me, it was to do with the repeated statement that OP’s husband sees this as causing the end of the relationship with his son which seemed to suggest a real willingness to throw the relationship away. The OP has now confirmed that is not the case.

TigTails · 10/08/2026 13:56

So would I. 👀

if he’s the beneficiary of a trust then he may well have a legal right to information it.

Greenhairedmonstor · 10/08/2026 13:06

Any assets generated from their grandfather is theirs.

My husband is really upset and thinks this is the end of their relationship and it will affect his relationship with his younger child as well.

I am tempted to talk to them generally that while my lifestyle for want of a better word, is subsidised like most married couples I also am not without resources and my children have a father.

I wouldn’t discuss finances with your step-son at all, it’s got absolutely nothing to do with him and I wouldn’t give him a feeling of power or satisfaction by discussing it with him. He’s coming across as an ignorant brat.

AprilMizzel · 10/08/2026 13:56

MyDarlingRose · 10/08/2026 13:45

No it’s not. Financial disclosure is based on the resident parent so his mums finances. His dads won’t come into it

That's correct but doesn't mean the DS here is getting enought to actually live off - and that may be driving this.

Its' all very well saying oh they can work - some courses make that hard and there is a lot of compettition for any jobs as many are in the same boat.

It's close to results day perhaps it's looking suddenly real and budgets have been looked at and gaps found maybe there's a worry he can't afford to go and this fuck up approach has come about.

I don't know - is something perhaps OP DH could ask about.

It does sound like a very rude request and major over step but 18 year olds can be very self absorbed and clueless - most parents push back and correct them not jump to cutting them off and going NC.

SplishSplash123 · 10/08/2026 13:55

I think your husband needs to talk to his children. Your stepson is well and truly in the wrong here, not least because he's no more "earned" the money than you have; for now it all belongs to your husband for him to do as he sees fit.

But I think the starting point needs to be your husband figuring out where his childrens' sense of entitlement comes from. Is there an unmet need/some sort of trauma from the separation of their parents?

In your shoes, I would stay well out of any direct conversation with the stepchildren until your husband has figured things out with his children.

I strongly advise you not to do this. Don’t get involved at all, it will be misinterpreted, deliberately or otherwise.

Keep telling yourself when they go low, we go high. Classy restraint is what’s required here.

ChequerToRed · 10/08/2026 13:54

While we don’t know exactly what sort of legacy management mechanism is in place here (trust, FIC etc), if SS is not currently a named beneficiary, trust board member, or shareholder, then he’s entitled to know sweet FA. I’d take this as a warning shot across the bows and arrange a meeting either with the trust board, solicitors, or with whoever is managing the FIC and make sure everything is absolutely water tight, because if he doesn’t grow out of this grabby twat phase he could cause bigger problems in the years to come, especially if you find yourself widowed and the current beneficiaries start to dwindle.

Bonkers1966 · 10/08/2026 13:53

He may have been discussing the situation with his cousins. They all have parents who are benefitting from the estate. He may have received encouragement to step up and ask for details. Hubby needs to check in with his siblings. And calm down. This does not need to be relationship ending. It's a cheeky request but did he receive a holiday or was it only your child? It's the little things that hurt in a blended family.

OP, you work, you receive a rental income for a property and your kids have a father who supports them.

With all this, why couldn’t you pay for your own son’s school trip?

I think your step-child has a point and I wonder if your DH thinking it’s the end of his relationship with his child is because you are meddling in it.

Tell your DH to be the adult and talk to his son and reassure him.

Greenhairedmonstor · 10/08/2026 13:50

My husband or his siblings CANNOT diminish the assets but can spend the income generated.

My stepchildren know the terms of their grandfather’s legacy.

They both work hard as this RG university place demonstrates.

Someone picked me up on the use of the word subsidised. I can support both myself and my children however, like most people in a couple I live in an area of England and in a house that I couldn’t afford myself. I go on holidays that I might not otherwise be able to afford every year.

My elder stepchild is intelligent and I don’t believe he is being egged on by his mother.

Any money spent on my children like that ski trip and family holidays is resented bitterly. 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.

Someone said my husband is eager to let his children go, this is absolutely not the case. He is terrified of losing the relationship. He supports them and SS will be supported at university.

I’m 50 my dad is 78 I don’t have a clue about his finances as they are none of my business. My own adult children don’t know my finances because, guess what? It’s none of their business

InWithPeaceOutWithStress · 10/08/2026 13:50

Your post is really confusing. You mentioned ss wanting an account of money spent on your children but haven’t clarified who these children are or why the ss would be concerned with this.

The most bizarre aspect of your post is that your husband considers this may be the end of his relationship with his ss. Does he not possess any conflict resolution skills or feel any need to parent and talk to his child properly?

You mention your contribution to the finances but has anyone explained this to the ss or are you both assuming him to know this via mind reading? He doesn’t appear to understand how the not a trust thing works. Perhaps your husband’s inability to communicate openly has led to this issue. Encourage him to talk to his child.
