DH has reneged on post nup he had promised (pre marriage) he would enter into to protect family inheritance

Before we got married c 8 years ago, I had said to my DH (financè at the time) that I’d want a pre nup to protect a significant family business, and other inherited assets, that would likely be passed down to me. The value of the inheritance will be significant and so with my sensible hat on I am keen to protect that in any way I can.

For a number of reasons that prenup wasn’t entered into before we married, but he discussed with my Dad and gave him his word (and he did likewise with me) that he’d enter into it in future before any interest passed to me as part of the family’s estate planning. This has been looming a while but we are now at the time where this needs sorting. I have tried and tried to speak to my DH but he is always busy (though I am the main breadwinner, by some way…), explains his fear that I’ll take the family house off him (the post nup leaves the entire family home to him exclusively - valued at £900k and minimal mortgage) and leaves me with a small property rental and ensures that any interest in the family’s wealth remains my asset).

He is so apprehensive about entering into it that he called my dad outright a couple of weeks ago and asked him what he was expecting my DH to do. This is something I’m driving because (a) we are in a bad place and have been for a few years and (b) I can’t bury my head any more and need this sorted. My father was cross at the phone call as he was caught off guard, and on reflection why such reluctance now to discuss with Dad - when he left it years ago on the basis he’d sign something.

He won’t discuss it with me, when I go into his office at night to ask whether he will engage with me on it he tells me to get out, he is exhausted and doesn’t have time to talk about it let alone look for a solicitor that will advise him on it (I’ll pay all of those fees) and ends up putting noise cancelling headphones on with music blaring until I go out. If I stay there he says that he will lock his office door so he is left in peace.

I am at my wits end and had always said to myself that I can put up with his treatment at home (the above being an example) but am so concerned that this is the final nail in the coffin of my marriage (3 young DC under 7, one of which is extremely anxious and constantly worried so I don’t know what a separation would do to her).

If I were to bring our divorce papers I am almost certain he would start to engage - but what concerns me is these post nups are only valid for 5 years and need to be kept under review every 5 years. If he won’t engage now then god help me in 5 years’ time again.

Please be kind as I am worried sick but appreciate any advice. I’ve even considered initiating a divorce for purely financial separation whilst continuing to live long term under the same roof - I am willing to give the marriage everything I have got but the financial worry I am carrying is killing me. I think he expects that he will fail to engage and it will all go away because I’ll get bored of chasing him but fundamentally this is such a U turn from what he promised me before we got married that I am not sure I could ever get over it.

What is the point of him? How have you not divorced him already? Do you want your children growing up thinking this is what a relationship looks like?

This. If you think that staying together for the kids is best, then you are gravely mistaken. They see the way he treats you like dirt and his obvious lack of any fatherly love for them, and it will be driving painful wounds through their hearts over and over again. Especially when they see a man, their own dad, being so cruel to their mum.
They will in no way be 'shattered'. Have you not considered that your daughter's anxiety could be greatly relieved when she's removed from this toxic environment and you can protect her yourself?
Sometimes you gotta pull the band aid off to get any healthy healing. And certainly this toxic environment you're all festering in is just going to get worst.

Sittingonbenchdteaming · 15/04/2026 18:49

I have never heard of a post nup !

If you are unhappy, apply for a no fault divorce ASAP

Meadowfinch · 15/04/2026 18:53

Your dad should make it known that he has changed his will, so family wealth will pass direct to your children but held in trust until they are 21. Then you file for divorce and end the relationship, dividing your shared money 50:50.

After you are free, your dad can change his will again to benefit you.

Your children will be less anxious when not being forced to live with a sham marriage.

DotAndCarryOne2 · 15/04/2026 18:56

Start divorce proceedings. If that concentrates his mind enough to follow through on his promise, then fine. If it doesn’t follow through with the divorce. Are you sure a prenup would stand up in court - many don’t in the UK.

@MyMonthlyNameChange He doesn’t do any housework nor childcare. Refuses to take time off for the kids during school holidays so I get by with help from my parents and I take 1-2 days per week off during summer holidays to save on constant childcare and clubs - he refuses to take one of those days and tells me to put them in clubs (which I pay for given higher £). He doesn’t do the housework - I have a cleaner. He says that his job is far mor vulnerable than mine having only been there 2 years (I’m senior and 20+ years in my company). He is always busy. Then at weekends will find something to keep him busy to avoid any conversation.

We sleep in separate beds, he does his own washing. He mostly sleeps in at weekends until 8:30 whilst I am an early riser and up with the kids. It’s truly awful and I have asked what we can do so I can take a step back from work (my job is super intense and high pressured) and his response has always been that he cannot put anything else financially in. He pays a v small mortgage and a small amount towards childcare, but I pay everything else. My car needs changing and he doesn’t have the time to help me with what I’m looking for, my property rental has maintenance issues and he is hopeless at helping or engaging so I have to work it out myself on top of everything else or ask dad for help.

He makes his own dinner every evening as refuses to eat what the kids and I eat- he wants scrambled eggs every single evening. He cooks said eggs and I come into the kitchen the next morning 60% of the time with the remains of his dinner from the night before still on the floor / on the kitchen counter because he hadn’t been arsed to clean it.

@mamato3rascals what kind of role model is he for your kids based on the above? That is reason to get yourself out of this mess right now. I’m sorry but you are doing everything, he is more like a lodger and he’s strung you along. I’m sorry to say you never should have married without the agreements in place. Don’t think staying together is right for your kids - it is not. I’m sorry but I really think you should extricate yourself from this ASAP. Please seek legal advice.

mamato3rascals · 14/04/2026 22:20

As ridiculous as this sounds, one of the things I have been considering is divorcing (to cut the financial chord and because we are in dire straits) but to keep living together? I am just thinking of the kids who would be crushed

The kids will be more miserable if you and your DH are in a miserable situation. They will adapt, and perhaps be in a better place.

TheDenimPoet · 15/04/2026 12:46

You didn't get the prenup sorted, and you went on with the wedding regardless. You're now paying the price for this. You're married, everything is 50 50. "His word" won't stand up in a court of law.

It's shit, but you really did bring this on yourself.

I bet OP really needs to hear that right now.

Swiftie1878 · 14/04/2026 22:04

Before everyone piles in, just to say, if you were a man you’d be torn to shreds on here.

You are married. What’s yours is his. What’s his is yours. You have no prenup or postnup. Why would he sign now with your relationship on the rocks, especially with three young children in the mix - he’ll need finances to be able to see them and accommodate them, just like you.

Do what’s right for your whole family and not just you.

Exactly this. Why marry someone you’re so desperate to avoid sharing your wealth with? I would very much like to know how care of the kids is shared given that OP is such a high earner.

Edit: I just read your comment about how little he does with/for the children and you. What a twat! I hope you find a way to protect the cash from him.

LisaVanderpumpy · 15/04/2026 20:05

Sounds like you have plenty of money so why can’t you just split it

thats what marriage is
an agreement to share all that you have
for better or worse

get divorced and split it

T1Dmama · 15/04/2026 20:14

sorry .. you’ve been married 8 years and haven’t sorted this already?

Aanyway can you not divorce him now and half the big house and small rental equally.. as your dad is still alive the inheritance won’t even be considered! Since it’s not guaranteed yours anyway!

Get things moving asap… before the inheritance is considered… he will soon see he can walk away with a big house if he signs or otherwise the houses are both sold and halved and he’d likely be worse off!!

mamato3rascals · 15/04/2026 12:14

I could literally have written this myself. This is exactly my life (pre divorce, obviously). He makes all those claims to me. I am shook.

This happened to me, too. From
what you are writing he is biding his time and probably will blame you for ‘divorcing him
out of the blue’ just like my ex. He ‘had no idea’
and ‘believe everything to be great’. This is how they get the sympathy and turn you into the bad guy.

Speaking from experience, both you and your daughter will be happier and better off once you’re free from him. She likely feels something is not right at home, they are so intuitive. He is manipulating and gaslighting her as well as you. Get her into therapy and cut yourself loose.

mamato3rascals · 14/04/2026 22:14

I don’t think that filing for divorce then signing a post nup (should he then decide to engage) would work. I think the post nup would be classed as him entering into it under duress.

Looked at trusts- that’s an option but it makes access to anything within that trust v difficult should I ever wish to draw on it, and my understanding is that once I draw on any funds from the trust it’s treated as a marital asset and so susceptible to being treated as part of the “pot” in the event of a divorce. I’m not saying I want to live off that fund, but it is likely I will need to use some of the funds in retirement / for kids school fees etc.

Speak to a tax and trusts lawyer. If the trust has the kids as a beneficiary then their school funds would be covered and you could get easy access.

Speak to a lawyer. He isn't going to engage.

VoiceFromThePit · 15/04/2026 20:24

You need a financial separation.

Then once that is sorted I suggest the bulk of the inheritance bypasses you and is put in trust for your kids with you as the sole trustee.

Laura95167 · 15/04/2026 20:56

Where are you because in the UK pre-nups and post-nups dont mean much.

Tbh though I think you should divorce him, youre in a rough patch, he lied to you and kids arent happier with two parents who aren't happy.

Mix56 · 15/04/2026 21:08

As several other PPs say.
Go & see your Dad, tell him the truth. That you would like him to safeguard the inheritance by seeing a lawyer specializing in this. A Trust or other method to be determined ..
Meanwhile you are divorcing your H, for multiple reasons that your parents already have seen & understood.
Tell your H that as he has refused to engage with the pre nup, that your Dad has changed his will to a trust for DC, & btw you are filing for a divorce.
Get shot of this miserable selfish leach

MyHorseAndMe · 15/04/2026 21:10

If you think divorce is inevitable, then kick it off now and sever all financial ties before the inheritance

changeme4this · 15/04/2026 21:24

Have a very frank discussion with Dad. He is in the prime position (if I’m reading your post correctly) to divert your anticipated inheritance.

my SIL (not in the uk) had terminally ill MIL set up a trust which SIL would benefit from to avoid her creditors from receiving inheritance funds when she later filled for bankruptcy.

friends currently going through separation, one has a trust which the spouse thought they would benefit from however are unable to touch the main asset, only the income derived from it. That isn’t a 50/50 thing either, where the trust has supported their life, the other spouse is entitled to share those purchases in asset distribution…

so there’s a fair bit involved, but you and dad can along with a legal team, make changes now.

this is no way to live.

HarshbutTrue2 · 15/04/2026 21:24

It is normal for manipulative men to blame mummy for the divorce. It is normal for them to somehow try and use the kids against their mother. It is also normal for them to claim 50/50 custody, although they don't really want it. They use it as a bargaining tool.
I have heard that divorce affects children less when they are younger. They soon get used to life without daddy. They grow up without him and don't miss him.
We all know that it's hell for children to grow up in a house with arguments, sulks and bad feelings. They would be walking on eggshells. All the kids would be suffering from anxiety.
Older kids and teenagers seem to suffer most from divorce and are more likely to go off the rails.
One of the saddest stories I ever heard was a little boy at primary school, when asked what he wanted for Christmas he replied 'i want my mummy and daddy to stop arguing'.

His wish came true. Daddy beat mummy up on new year's eve and they'd split up before the start of term.
Don't let your kids be like that.

Gettingbysomehow · 15/04/2026 21:31

Why on earth do women marry these duds and put themselves at risk like this?
Presumably intelligent women.
So they can wear a fancy dress and be the centre of attention for a day?

Fantomfartflinger · 15/04/2026 21:34

I think he appeased you by saying he would sign but had no intention of doing so. I actually think he sounds dangerous, what will his reaction be to a divorce be careful. This seems calculated. I think he married you for the money and in fact he will win even without the inheritance as he seems to have come in with not much and will exit with 900k. I’d fight the 900k too tbh, unless it’s in the pre-nup ( although why you offered a penny idk). He can’t even pretend to like you, he isn’t a very bright strategist. I would run to the solicitor tomorrow. Do not be complacent OP. What was so great about him when you met? Is he really good looking or something? Because you are a catch!

MMAS · 15/04/2026 21:36

With the greatest of respect to MN why in Gods name are you on here looking for advice now. It would make far more sense to be talking to Lawyers.

You made a mistake big time by not having something in writing before marriage. What you cannot do now is decide your husband should just fall down and accept what you want. As another poster said, if it was the other way round MN would be in uproar.

Take the bull by the horns and seek proper legal advice. Why put three children under the age of 7 through that atmosphere when you have already decided to give him the property and you are not homeless because you already have another property to go to.

Until you decide to divorce, it is unreasonable to accept your family to make any decisions. If I was them, I would actually take steps to ensure you did not get anything or, at the very least, wrap it up to protect their Grandchildren. By any chance is this what your actual problem is i.e. being cut out.

Many many women would wish to be that lucky to have another property they could go to.

Not fucking rocket science is it? He's a user and is currently living his best life, thanks to you.
You need to put a stop to it, now. Stop with the guilt of breaking up the family/trashing the kids lives. He does fuck all for them and makes you miserable, their lives will be richer not poorer if you divorce this man.
He is bringing fuck all to this table, why are you continuing to enable that?
Fuck him off before he gets his hands on the assets your family have worked hard for.

Fantomfartflinger · 15/04/2026 21:45

If I read it right he signed the prenup but not a postnup. No prenup then no marriage so he had to do that part.

From his behaviour I honestly believe this was calculated.

He should walk away with as little as possible. He is a scheming person.

SkylarkKitten · 15/04/2026 21:52

When divorcing, my ex tried to get half of any future inheritance. It was thrown out as ridiculous because potential inheritance is not an asset.

If you're truly intending on divorce, then do it now with a clean break agreement.

However, if you're thinking of divorce in order to protect inheritance, I'd think carefully about that. Divorce isn't just admin. It is truly horrendous in most cases and very costly. Everyone is affected.

The only way to protect assets in the UK is by setting up a trust. It's expensive to set up, and there are tax rules surrounding trusts.

It sounds like you need tax and legal advice. If your assets will be considerable I'd suggest getting professional help and not advice from Mumsnet
