Step children and inheritance

181 replies

WineBeforeWhine · 06/02/2026 08:43

I have two step children who were adults when I married their dad. We then had two children. My parents left me considerably more which went into the family pot while we were married. My husband died and I was left everything. I’m now having to redo my Will. My question is should all four children be treated equally or is reasonable to leave my own children a higher percentage of my estate something like 20% for the stepchildren and 30% mine? I’m struggling to get it right.

OP i would take out your inheritance from the pot, split that between your dcs, then the rest of the pot that is made up of yours and your late DHs estate is split 4 ways. There is an argument for taking your inheritance out for your dcs, splitting what’s left in two pots, viewing one yours and one your late DHs and then splitting those, DHs share between his 4 dcs and yours between your two. This would mean effectively you leave nothing to your step kids, they just get a portion of their dad’s share. But I think I would want to give some of my money to step kids as well.

There’s no right or wrong answer to this. As long as the step kids get something from their dad’s estate (assuming there’s something to inherit!) then how you split it is down to how you feel and your relationship with the step kids.

I would have thought that your children would get 1/2 your estate each and 1/4 dads and step children 1/4 days so all things being equal then your DC get 37.5% each and his get 12.5% each. But I appreciate I do not have all the facts and if their mother has never been in the picture etc things might be very different in reality.

That’s exactly how I have organised it with my dcs and sdcs. My half goes to my dcs and my late dhs half is split between all his dcs.

If their dad didn’t leave them anything (that was awful of him), I would include them equally.

As my mum and stepdad’s will currently stands, it’s 60% me and 20% to each of his 2 children. I’m not even a joint child. And it’s mostly his money. I think it’s shit of them personally.

Exactly this. Just split the inheritance equally between all the children / siblings.

Unless, of course, you want a bomb to go off after you pass away and for everyone to fall out.

EvangelicalAboutButteredToast · 06/02/2026 11:32

I think it’s lovely that you are considering this so carefully as those children sound as though they could miss out altogether if people werent being so considerate, as their nuclear family has now split into quarters with another four siblings and new marriages.

I think the best thing to do would be to give them inheritance from their DF just now if you can

I was actually going to suggest the same thing. If you can, you could give your step-children their inheritance now, as they are already adults. Then you leave your own children 50% each in your will.

I think it would be fine to give your stepchildren 25% each of what was left to you by your late husband and rather than leave anything additional in your will, I would help with one off costs where you can as your husband would have done.

SplishSplash123 · 06/02/2026 11:33

Completely agree you are being reasonable to give your own children more - both on the grounds that some of it came via your parents into the pot, and on the basis that SC will inherit from the other parent too.

I appreciate there is nothing you can do about this now, but for anyone else reading - please ensure that these discussions are had whilst both are still alive and that the wishes can then be communicated to the children (e.g your husband could have written a letter before he passed explaining the decision made, the letter to then be given to SC after your death. There is a risk now that they could feel you've gone behind their dad's back and changed your will after he has died. Hopefully not the case, but always best to try and prevent such issues!)

He could set up a life interest and you could live there for the rest of your life, if he dies before you. Problem solved.

Life interests in properties also cause problems later though. You might think you’ll want to stay in the house until death, but sometimes you need to move. It limits the step mother to staying in that location, when work /family might relocate. It could be the property is no longer suitable, (step parent needing a flat or bungalow, or just a house with a smaller garden) but not having the money from the sale to buy something more appropriate - rarely do life interests in property allow for it to be sold and a new property with a life interest in that be bought.

Consider distributing what DH brought into the relationship at the beginning to his older children now.

Then you have more freedom to use the remainder to pay for your own nursing home etc.

Keep the value of your inheritance for your children only.

What you amassed and earnt together could be split between all kids -1/8 for each SC and 3/8 for your shared children - reflecting that DH had four children and you had two.

NeverSeenThatColourBlue · 06/02/2026 11:48

It's a bit simpler for me because we have one "ours" baby and one of his.

We have discussed this and decided that the fairest way to split inheritance will be 2/3 to my daughter and 1/3 to my stepdaughter.

However, my parents have floated the possibility of paying off our mortgage, in which case we would consider the house separately and leave that to our daughter, with the remainder of our estate being split as above.

We would be looking at this completely differently if it wasn't for the fact that SD stands to inherit a lot from her Mum and Grandmother, and already being likely to inherit at least half of a property worth about 3x the value of ours.

Why should step-kids get equal shares of OP’s parents estate? Thar’s ridiculous.

Barnsleybonuz · 06/02/2026 11:51

What a terrible father to leave his children nothing and rely on you to do it. He should have had provision on his will and yours should have had it too on how they should receive their money. Yes of course you need to live but the proportions of how all the money should be split on your death should have been laid out.

WineBeforeWhine · 06/02/2026 10:31

We had discussed this before he died. Had agreed on 12.5% and 37.5% but I’m thinking I’ll increase the % and wanted others opinions.

If it's what your DH wanted, then that is what you should do, and explain why in the will or in a letter. It's simple, and easy to justify - the remaining assets of each partner of your marriage will be split equally between that partner's surviving offspring. Trying to do anything else based on multiple factors (inheritances, the financial history of the marriage, expectations from other relatives) is too difficult and bound to create an opportunity for someone to feel aggrieved if they're that way inclined.

Barnsleybonuz · 06/02/2026 11:53

I also strongly believe that saying they’ll inherit from the other parent is utterly irrelevant, that’s nothing to do with you.

Whatnameisif · 06/02/2026 12:01

WineBeforeWhine · 06/02/2026 08:49

Funnily enough, this is how it is at the moment. Yes their mother remarried and had two more children.

I'm in almost exactly the same situation in terms of adult step children and this is what we've done too.

My step children have their Mum to inherit from.

At the end of the day though, it's your money now to do what you like with.

Only in so far as the inheritance the DSC should get from their dad.

OP is allowed to take their other potential inheritance in consideration to decide if they should get anything extra from her own estate.

InterIgnis · 06/02/2026 12:05

Whether or not they’ll inherit from their other parent is irrelevant. Not your business, and not your problem.

It isn’t ‘unfair’ that your DH left his estate to precisely whom he wanted to leave it to. His older children haven’t been denied anything they were entitled to.

Remove your half of the joint assets, and your inheritance, to ring fence for your own children. What is left divide by the number of children your DH had.

He left it all to me so I could stay in my home, and have enough to live on, why is that so difficult to understand? He wanted me to be financially secure. His kids both have spouses, their mother to inherit from, plus their spouses parents to inherit from, so they’re hardly suffering.

MN always acts like every household is really an aristocratic household with a presumed entail keeping the property in the hands of the family and excluding in married women. Instinctively they act like joint marital property should be understood as “.really” belonging to the male line or at a pinch staying in separate female and male lines.

WineBeforeWhine · 06/02/2026 08:52

Yes good point about getting the solicitor to say why it was done that way in the Will. I hadn’t thought about that.

You can do a letter of wishes alongside the will only to be opened in the event that the will is contested, which would explain your rationale but only if someone was unhappy enough to go to court. That’s what I’ve done; I’ve left my estate to a friend’s child rather than DB or his child and if DB wants to challenge it then he’ll know what my rationale was; if he respects my wishes there’ll be no need and the letter will stay unread.

nomas · 06/02/2026 12:10

Whatwerewetalkingabout · 06/02/2026 10:53

Yeah your friends Mum really fucked over her step child and your friend should have made things right if she had any empathy with at least a quarter of the estate. But most of all her Dad should have ring fenced some inheritance for her. What an absolute crying shame the daughter didn't inherit from her Dad and her little sister got everything. That must have made her feel worthless.

Agreed.

Rewis · 06/02/2026 12:15

We don't know if the children will inherit their mother. If her will is similar to your husbands then if she goes first her husband might want to leave everything to his children. I would not use potential inheritance from mom as a baseline for anything. I do think husband did a very risky move and I would not encourage anyone with kids from different relationships to just trust their partner. It is great that you op are leaving something to your step children. I know too many people who won't.

But yeah, it is fair that step children get less cause husband had 4 children and you have 2. So "your share" should be divided by 2 and "his share" in 4.

He left the house to his ex wife and we bought a house together. His kids are in my will, hence my post.

Edited

Yes but when you and he bought the house together did you each contribute equally to the deposit and repayments?

My dad has left everything to his second wife. They don't have any kids together, but he has four of us. There is a sizeable pot of money (>£1M) but I imagine we wont see any of it. She's ten years younger than him but also can't cope well on her own so she'll be in a fancy care home if (when) he dies before her.

We wont see any of that money but it is what it is. Wont inherit anything on mum's side either as she spends every penny she gets as soon as she gets it.

Dad's always been clear he is leaving her everything so we know where we stand and it won't be a surprise, this will reduce any fallout. I suggest you do the same.

My FIL is leaving everything to his second wife. She is younger and healthier so itnis expected that she will outlive him. She doesn't have children so she will be giving everything to her nieces/nephews. While I don't necessarily agree with this decision, I at least appreciate that he has been open about it.

TessSaysYes · 06/02/2026 12:22

I'd subtract your parent's inheritance first, and leave that only to your children.

Then, for you and your partners wealth, I would divid that in half.
Your partners portion is divided 4 ways between all his kids.
Your portion is divided just between your 2.

I think that's the fair way.

The step kids presumably might inherit from their mother and maternal grandparents. Your children will inherit nothing from step children's mother, right.

WildLeader · 06/02/2026 12:26

This is the way things currently stand with us. Although I do think DP needs to make arrangements to leave them something.

his kids DMs got huge amounts of money and property when they divorced and it’s important that he doesn’t leave ruinous amounts but they will expect something.

they will inherit a trust fund once I’m gone too.
