DH has 2 previous children from ex wife, i have my own ds and we share a child together. my husband bought our house, put in his own deposit and his name only on mortgage as i had bad credit and currently in a debt management plan trying to get debt free.
i do pay towards house household and bills etc
topic came up if were to pass away before me, he said the house would be paid off and could remain living there. but when and if house was sold his assets and property would be split 4 ways 25% each to his 2 dc our child and me. nothing to my own child who is his stepdaughter. what are people’s thoughts on this ? i feel i suppose its fair as its all his money and not mine.
i will one day inherit from my parents and i would split that between my own 2 children so i suppose its fair. my step children will also inherit a large amount from their own mother. ak

So you would will your money to your own children and not his... Yet you question when he is doing the ecact same thing?

IMO the split is with all 4 children, and any inheritance you are fortunate to receive gets split between the 4 as well.

how old are the children? I’d be more concerned about your own living arrangements if something did happen to DH if you only have 1/4 interest in the property.

So do you think that her step children's mother will leave money to OP's children?

Stompythedinosaur · Yesterday 19:26

Seems like a pretty standard arrangement I would say.

Fair enough.
His assets go to his children and you
Yours go to your children and him

If I die, then everything goes to DH, and vice versa. Its only when the last one dies, does the money (if there is anything left) go to children.

If you die first, you do know that if your DH remarries, it renders this will null and void, right? He can also change his will any time he wants.

I am so glad that I live in a Napoleonic law country, where I know my child is protected financially.

The legal position is different than the moral one. I don't think your stepdaughter should inherit anything from him. In my situation my children will inherit everything I have - mainly because the house was paid off by their late husband's life insurance. It's the reason I will never marry again - there's too much risk. My DP's adult children will inherit his assets. He lives in my home and isn't entitled to anything from it, other than his personal effects, should I die. My will is clear - he will have time to vacate (depending on the age of my children at my death).

I think for his step daughter it would depend on the age of the child, how long they have been in each others lives, is the child in contact with her biological father, does she call him dad?

My stepdad, although he is no longer with my mum, has put me and my sister in his will. Majority going to his biological daughter (my youngest sister). My mum gets some also. We were down as a set amount, but he changed it to a % incase he lives longer and has less money to give.

There are lots of factors but overall I think you are unreasonable to think your daughter should receive anything.

Also I would suggest getting more clued up in regards to money, so you aren’t putting yourself in a bad financial position again.

(Current house value - ((deposit / house purchase price)*current house value/100)/2 = Your property value

(Your property value/current property)*100 = your property percentage

100-your property percentage= his property percentage.

Then you each will the percentage of the property you own to your own direct dependents.

Worked example:
House value of 300k
Deposit 10%

300,000-30,000=270,000/2=135,000 (your property value)
135,000/300,000*100=45 (your property percentage)

45% of property left to your DC1 and DC2 (22.5% each)
55% of property left to DSC1, DSC2, and DC2 (18.33% each)

DC2 gets the larger share owing to him inheriting from both, but everyone gets a share owing to the fact that whilst his name is on it, you have still been a family and contributing to the mortgage together.

It’s a shared asset whether in his name or not, he needs to put your name on it and stop treating you like you are just a kept woman.

Norberta · Yesterday 19:57

If you wanted to make it more fair you could increase the proportion of your inheritance you leave to to your eldest and only leave a smaller portion to your shared child so they have more chance of netting out with the same amount regardless of where it came from

You can do it easier if you want by just doing:

100% - original deposit percentage (eg 10) = 90
90/2 = 45 your share
45+10=55 his share

Get legal advice on beneficial interest but frankly, outside of this, once your child with him is 18, it was mostly his money so it's morally his choice who to gift it to under our laws, so you might have to then move if the house is sold.

Look into getting your own, separate investment.

I would say that’s fair. But I’m not on the side of idolising SC to ensure they get everything which a lot of mumsnet seem to be.
I’m in a similar situation in terms of SC, shared child etc. But we’re both on the mortgage. We have 6 children between us so we’ve done it so that my half goes to my bio 3 and his half goes to his bio 3 (one of whom is mine). However it was solely my deposit, and I’ve protected that so that only goes to my 4 children. Which won’t amount to too much anyway.
Has he got this in a will then? As others have said I presume it will go to you anyway if you’re married and he hasn’t got a will tha specifically says this. But either way if you’re not happy, you could always give your 25% to your child.

Edited

This, your deposit is protected, the rest is halved, then each half is split between bio kids of the person whose half it is.

@nevereveragain2 : The only thing I’d wonder about is this ‘i do pay towards house household and bills etc’

When you say ‘towards’, do you mean your share? It is just that if your DH paid towards a mortgage on a house (an appreciating asset, usually), and you picked up for most of the household bills, food costs etc., that would skew things slightly.

It doesn’t matter, they’re married, marital assets, contribute whatever suits the family

stichguru · Yesterday 20:27

Totally fair his money goes to his children.

Laura95167 · Yesterday 20:29

If youre planning to only provide for your 2 children why are you complaining hes doing the same amoungst his 3

Not necessarily, depending on whether he’s protected his financial interests, and how well.

Assets and finances can be kept separately, even if married.

Applesonthelawn · Yesterday 20:47

No he really doesn't need to include your stepchild.
It sounds like he has made arrangements for you to live in the house as long as it is not sold - so you will not be made homeless. Usually that arrangement would allow you to move home and still the new home would only go to the beneficiaries upon your death. That is worth checking, because it's not implied in your OP. We have that arrangement in our wills.
I think it is quite generous that he leaves you 25% if he has made the arrangement for you to live there as long as you wish, and to move house. Your child who is his stepchild could inherit that 25% eventually, upon your death, if you wanted.

Genevieva · Yesterday 20:47

That’s his will. Make sure your own will leaves your assets to your children. But also make sure you start saving and don’t contribute more to running the house.

RumPidgeon · Yesterday 20:53

Varnicka · 29/09/2026 12:03

What are you leaving him OP?

I was going to ask that. He cuts his pie 4 ways but you just split it between your kids.

Calliopespa · Yesterday 21:07

I think in these circumstances it is right that his dc only inherit.

You are already inheriting your share which presumably you will eventually pass to your dc.

I don't believe existing children should suffer because of a second family set-up. In reality their inheritance has halved already ( because you and your shared dc are now in the picture).

ETA if you felt this really was unfair on your existing dc, you could always channel your 25 just to that child, meaning all four would eventually get 1 quarter each.

Any other set-up means his pre-existing dc ultimately get less than everyone (eg divide by 5, with 3/5 portion going to you and your 2 dc, with your fifth presumably staying with your dc when they inherit from you. That leaves his dc with less each than yours.) His approach is appropriate I think.

Suszieq · Yesterday 21:16

@nevereveragain2 are you giving any inheritance to his dc?

dreamingofgoodhair · Yesterday 21:35

Lexibletheflexible · Yesterday 19:00

Because the OP laid out their plans which included the kids inheriting.

She said she’d inherit from her parents and the SD would get an inheritance from her mother -
nothing guaranteed.

Soonbbbqweather · Yesterday 21:37

Absolutely fair. He’s providing equal shares for all three of his children and you as his dependant. The step daughter will inherit from you with their sibling presumably and also from your family and her father’s family. Potential inheritance is not something I would dwell on as a lot can change - you could divorce/die first - and nothing divides and upsets a family more than thinking about money they may never receive.

DaisyChain505 · Yesterday 21:39

@nevereveragain2 Won’t be back.

She’s been told she’s being very unreasonable and she won’t like it.

You wouldn’t be putting his children in your will if you had any property or assets so why do you expect him to put your child in his will?
