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.

maybe he thought his kids will do that anyway and won’t need instructions to put their kids first. like he put his kids first.

He should have, but mistakes happen. That doesn’t mean he’d be happy about this.

Legally yes. the man can spend how he wants. He can burn it if he wants.

but what does it say about him that he would do that and not prioritise his biological child.

this man is able to do that and spend it, BECAUSE his father ( the grandfather ) prioritised his children and made sure they were taken care of.

i highly doubt mumsnetters would be saying all this and not feel some type of way if this was their dad or the ex husband prioritising someone else’s kids before his own

I highly doubt mumsnetters would prioritise their husbands kids over their own

Exactly!

JHound · 10/08/2026 21:02

I actually cannot believe the nerve of the SC to seek some form of entitlement to what is essentially his father’s finances. People will blame this on “blended family” BS because Mumsnet is very weird towards people divorcing and moving on. But yes some of your husband’s money will be spent on his current household. It’s absolutely non of the son’s business how his father’s income is spent unless the the son was missing out.

The father should simply say any money spent on the current household is from his income and any on his elder son was from the inheritance.

I would also question how I managed to raise such a disrespectful child.

BlueDillieDillie · 10/08/2026 21:00

Has it been carefully explained to the young man how the assets and money have been left? Now that he is 18 he could know the legal obligations. Show him a copy of the will the will. Maybe he has misunderstood things. Any other teens could learn as well.

JHound · 10/08/2026 20:57

Your husband needs to tell their child to FO.

OP, OP's skiing child and that child's father are money-grabbing scrotes, no, for taking money to pay for a child that is not the SS's father's child? Why are they all fine to benefit from the SS's father, but the SS is not?

This is so typical of blended family crap and it's always the first family that miss out.

Absolutely.

‘Blended families are such bullshit.

What’s the plan? Or is it too late and he’s already been shown?
Lots of questions, more clarity needed please.

The Little Scrote's Father's finances are none of his business.

Exactly.

All the second marriage posters clamouring that the stepkids should get screwed over.

Step families are rarely happy units.

This thread is sickening.

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.

So basically your SS has no legal right to see your ‘finances’ or to insist on any form of reimbursement on money spent from your own assets after your DH passes ? If the assets will be sold and he will benefit from a part share of the sale proceeds, the income they are generating now is nothing to do with him - I would be questioning why he thinks otherwise . I would make sure that you both have watertight wills too, because he sounds a grabby little fucker. I’d tell him to whistle.

MatronPomfrey · 10/08/2026 20:41

What a rude and entitled SS. Your DH’s income, regardless of source, can be spent anyway he wishes. He could loose it all in a casino every month, if he wanted to. Maybe SS doesn’t fully understand how the inheritance works and your DH needs to explain the asset that will be sold in the future and that the income received from that doesn’t impact his inheritance.

Somersetbaker · 10/08/2026 20:38

Suggest the entitled little arse familarises himself with Arkell vs Presdram, in particular Presdram's response.

Tablesandchairs23 · 10/08/2026 20:25

Your husband needs to tell his son to wind his neck in. His finances are nothing to do with his son. I'd be fuming.

Kate011 · 10/08/2026 20:21

very interesting how when mumsnetters make threads about being step parents and financially supporting their stepkids and inheritances most replies are they should put their own dc first

adverteasing · 10/08/2026 20:15

I don't get this bit. There could be 30 years between the first and last sibling dying.

MademoisellePraline · 10/08/2026 20:14

The more you look at it, this has got absolutely nothing to do with what the grandfather has left to the grandchildren, because that's ring fenced to be untouched until the dad and his siblings die.

This is about a grabby 18yr old wanting anything not spent on him and his sister, by the dad, as some kind of "add back" to his dad's bank balance when his dad dies.

If the step child gets a £600 laptop, this is "unacceptable" for his dad to have bought it, and the stepchild's mother should reimburse the £600 on her husbands death, as cash for the "real" child to inherit.

What a nasty, greedy little prick. The dad must be so embarrassed.

I think the DSS is unreasonable, but it must be really hard when your parent chooses to support someone elses kids. Its probably not really about the money & more the emotional side of it, that Dad is committing/dedicating a lot to you & your kids.

Yes my dad got remarried and lived with new wife and her son.
As a teenager I didn’t want to spend a lot of time with my dad, but neither did I want another child living with him seven days a week. Illogical I know but emotions often are.
Fortunately my dad didn’t have a lot of money, but every ice cream he bought for stepbrother was one he couldn’t buy for me. God knows what I would have thought about an expensive ski trip.

You do not know that is true. It is actually very unlikely that the original trust from FIL would be set up this way. It is more likely that all FIL’s assets have to pass to his biological descendants.

But everything outside of the trust can be given to whomever he wishes.

and depending on what the trust says he may be able to drain a whole bunch of it, in which case there could be very little left 🤷‍♀️

anyway it changes nothing, money is not his and he needs to stop being an entitled brat. Maybe look after himself and his own future and stop thinking about what he could inherit…the rest of the world has to work hard

Notonthestairs · 10/08/2026 20:07

Calliopespa · 10/08/2026 19:49

Actually wouldn't the logical conclusion just be to the extent of the value of what the father receives from the family inheritance/Grandfather's estate? Which I don't find as unreasonable as some others seem to.

The grandfather did the paternal thing and passed it down to the OP's DH.

Well the inheritance from the FIL is not being depleted.

The only money being spent is income (whatever the source).

So if the argument is that income can only be spent on the husband’s children then that is obviously unduly restrictive.

toomanycoffeecups · 10/08/2026 20:07

So if I have this right @Greenhairedmonstor, the set up is something like this.. Grandfather had an asset for example a business that generates a profit. That provides all his children with an income . Maybe not a business maybe just a significant investment. Nonetheless it provides all his kids with an income in equal shares. Some choose not to work and live a more frugal life on the income. Some use it to top up their salaries. All in all - how each child spends it is up to them. So if one wants to buy a yacht, another wants to take their wife and her kids on holiday or buy them a pony , then that is entirely their right. No strings. Then when a child dies. The asset or a proportion of the asset is sold and the capital raised from the sale is divided between the grandchildren. ?
If that is correct then there is no possible reason why he has any right to know the ins and outs of his father’s finances .

Does he have pure simple jealousy ? That his dad lives with other kids ? I’m assuming he has never wanted for anything. Except his lesser time with his father ? If so then I’m sorry but that’s the way the cookie crumbles when your parents divorce. He needs to find a grip and grab hold of it.. and his dad needs to sit him down and explain that he is a very privileged young man.

What an entitled little shit

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.

Does the step son enjoy the same quality of life as you and your children? I know you say your husband supports them...but is that 'CMS and no more', or the same level of holidays, comfort/luxury etc?

AcrossthePond55 · 10/08/2026 20:01

@Greenhairedmonstor

OK, let me be sure I have the facts straight.

'The Inheritance' (TI) as it is now is in actuality 'FiL's Legacy' (FL) that FiL bequeathed to his children (DH & siblings). It is set up in such a way that they cannot (or have agreed not to) touch 'the principal'. They split the income. Ipso Facto TI that is based on FL is NOT being depleted in any way. When none of FiL's children are living FL will be 'dissolved' and split between the next generation (step-bros and their cousins). Do I have this right or is it that when a child of FiL dies, their share of the income passes to their children until the last sibling dies then it is dissolved?

If so then your DH is not spending TI in any way, shape, or form on himself, you, his 2 DC, or your DC. He is spending his share of the income on the aforementioned people. That income is his alone to do what he chooses with.

Now, I'm not saying DH owes his eldest an explanation of jack shit. But, if he feels he wants to offer something more than just 'fuck off you ungrateful child', then he might explain the above and tell him that TI is in no way being 'diminished' and his share will pass to him intact. If he still wants a financial breakdown and a promise that 'whatever he thinks is due him' will be taken from your share of the house, then DH can tell him to 'do one' with a clear conscience.

Personally, I don't know who, but someone has put this into DSS's head. Maybe not recently, but at some point in the past.

Kate011 · 10/08/2026 20:01

Sorry but I cannot imagine prioritising someone else’s kids over my own kids. This is so sad.

And im sure op you wouldn’t either.

and “never have a relationship” seriously? He is a dumb 18 year old kid. This comment tells me this man relationship with his son was already bad. If he so quick to cut off his own flesh and blood

I feel like you are leaving out a lot of info.

HawaiiWake · 10/08/2026 19:58

Did the grandfather ever mentioned to the grandchildren that there is money for their education, such as university? Stepchild may have misunderstood and maybe not know much financial skills at this age thought he was due XX amount.

Calliopespa · 10/08/2026 18:56

if he continues down this arrogant path of thinking he’s entitled to wealth because of the sperm-based component of his DNA he may find out he gets none at all!

But hang on a minute: as far as funding from the trust is concerned, op's DH is also only entitled "because of the sperm-based component of his DNA" (what a vulgar description) as well - and the OP not even that, her dc still less again.

So what does that make all of them if the DSS is arrogant and entitled?

The distinction is that this is DHs money now, whereas DSS is eyeing up someone else's.
