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.

When doing wills did you not discuss the DC @WineBeforeWhine

I'd do an uneven but fair split as various PPs have outlined. Don't ask the solicitor to put the reasoning in the will - they're complicated documents at the best of times. Instead ask them to help you with a letter of wishes to go with it. This can explain the rationale behind the split and make it clear that you were trying to be fair. It can also make requests that your executors/the children might pass on small items to friends - for example mine asks that my DDs consider passing a particular item of jewellery to my best friend or her DD as she used it as her "something borrowed" at her wedding. These letters aren't binding but are useful both in keeping the peace and making requests.

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

I can’t do that, I’ve still got live!

Your husband has really screwed over his children from his first marriage.

I agree. What kind of father leaves his kids fuck all in his will?

Anyway - I'd leave it as it is now with most of your estate going to your kids and the remainder to the step kids. I wouldn't factor in their mum leaving them anyything - an inheritance is never guaranteed.

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.

I would look at what your husband left you and then consider half of this as for his kids and split that amount for his children as a starting point. You can the decide if you want to top up that from your funds (which include 50% inheritance from him). That way you are linking their inheritance to his money rather than abitory figure.

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.

This is the usual way of splitting things in blended families.
It assumes all assets were shared equally in the marriage so doesn't take account of your inheritance specifically.

Hurdygurdy123 · 06/02/2026 09:54

I'd really caution about relying on what someone else might leave people. They could spend it all, have to surrender it to care fees, leave it to a charity or split it in any way they like. You just can't know.

I would work out what their share of their dad's estate is and give it to them now.

More useful for them rather than waiting perhaps until they retire to inherit (I'm assuming you aren't that old) and then they don't need to be in your will - let them know that is the case.

You should take some legal advice on the correct way to do this but assuming you are young enough that is highly unlikely you need to be in care home or die in the next seven years, then it would be deprivation of assets and impact any future care home costs

maybe her own kids could also deal with the money now though? why should only 2 our if his 4 kids get anything now.

oceanmountain · 06/02/2026 09:51

This is how I would do it
37% each to your kids and his get 13% each

I agree with this. If you can afford it, I would give them a quarter of their dad's estate now (i.e an 8th of your total assets each). This would be fairest. If you can't afford it, an 8th in your will is fine.

If your husband had money or property he left you then I think all the children should be treated equally.

It won't be equal if the joint kids get the same as the two who also have another parent.

lazybone1 · 06/02/2026 09:39

@Usernamenotfound1 who said it was her decision?

it’s unlikely they’ll even know what’s in mums will so not something that can factor in

Which is why I said you can’t necessarily factor it in! 😆

Usernamenotfound1 · 06/02/2026 09:38

lazybone1 · 06/02/2026 09:33

Yes they will inherit from their mum and her new husband

Only if they have changed their will.

That’s not o/p’s decision though.

if their mum doesn’t leave them anything, that’s on her.

it’s unlikely they’ll even know what’s in mums will so not something that can factor in.

lazybone1 · 06/02/2026 09:38

I wouldn't factor in their mum leaving them anyything - an inheritance is never guaranteed.

I agree it’s weird to base what you will leave something based on what they may get.

Notgoodatchoosingnames · 06/02/2026 09:37

We have a similar situation, though my husband is still alive. But we've been doing the wills, and I have been struggling as feel like it sounds like our shared DC are favoured, but our financial advisor said to think of it as half each and split fairly between our own children. My DSC will inherit considerably from their mum, my son will only inherit from us. Now I have rounded up for the DSC so they also inherit something from 'my' half but my children won't inherit from their mum (and obviously shouldn't) so it wouldn't be fair to split equally. But we will be taking the kids through it so they understand. I would be heartbroken if they fell out over money when grieving.

lazybone1 · 06/02/2026 09:37

It happens all the time, people forget that a new marriage changes the will, they hope the step parent will just do the right thing etc.

JPNeed · 06/02/2026 09:36

The simplest and least contentious thing to do would be what several pp’s have already suggested which is your half of the estate is divided between all your joint kids and your husbands half of the estate is evenly divided between ALL his kids.

Depending how long you have known your step children and how close you are etc you could leave an extra amount to them from you. Say £5000 or £10,000 or whatever is suitable from your estate.

Adjusting the amounts for other reasons such as a previous inheritance would be more likely to cause upset. However if there are good reasons for it to be ‘unfairly’ divided such as one child having a disability that might mean they need more support in later life or something then make sure you detail why in the will.

Usernamenotfound1 · 06/02/2026 09:35

Do you have any idea of the actual sum you inherited from your dh?

we keep our finances separate for this reason. My kids will inherit everything in my name, Dh’s kids will inherit everything in his name.

yes this means our joint kids will get more, but as pp have pointed out they will get their share of dads estate and their share of mums estate- if mum leaves it to them of course.

my will leaves everything to my kids, dh gets a life interest in the house and my pensions to live off.

dh leaves everything to me. Depending on how much there is (currently nothing) I will gift some to the kids straight away, the rest will be invested. I shouldn’t need it, but it’s there if I do. Then it will be left between his kids in my will.

sittingonabeach · 06/02/2026 08:49

Didn’t your DH make arrangements for his DC, so part of his estate only in life interest for you and then going to DC?

this is what should have happened

GargoylesofBeelzebub · 06/02/2026 09:29

I suggest you speak to them all about what you are putting in your will and why so it’s not a surprise to them.
