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

mamato3rascals · 14/04/2026 21:56

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.

LAWYER UP ASAP

fabstraction · 14/04/2026 23:40

It won't get any easier with your daughter if you wait. If it's inevitable (and it does sound that way), I'd divorce him sooner rather than later.

ResultsMayVary · 14/04/2026 23:41

Sounds like you are already living as divorced under the same roof so I can see why you see that as the solution. If you get half the house in the marriage split if that living arrangement becomes untenable you could force the sale and leave?

WeAreNotOk · 14/04/2026 23:43

Just to echo everyone else, divorce, now. Job done. Why even live together afterwards, the marriage doesn't sound healthy at all.
A bit confused about wanting a pre-nup and never getting it signed before marriage. He had you marked for sure.
I rushed through my divorce when my DM died as I didn't want my 'DH' to lay claims on my inheritance, not that it was massive. The divorce came through way before the inheritance did. He said he wouldn't 'come after it' and I genuinely believed him but I needed that certainty. I think you do too.

I agree divorce is inevitable. We live completely separate lives. He’s just been away for 2.5 weeks with work, called the kids 4 times and each time he called I handed the phone to the kids, we didn’t really speak.

My issue is that he gets overly sentimental about things. Example being he won’t ever move from the family home because it’s where he thinks the kids picture their childhood (I mean yes bricks and mortar but we live such a dysfunctional life). He will therefore tell my daughter (which he’s done in the past when I’ve said we need to separate) that mummy wants to separate and mummy wants to break us all up. I have no idea how I come back from that with my DD. Other two are young and if anything I need to do before they get to the astute age of my older child, but I am tormented at her thinking I’m breaking up the family.

That's not 'overly sentimental', that's manipulative and emotionally abusive.

You need to get this done, OP. No excuses no procrastinating. You're going to regret it for the rest of your life if you don't.

MineThineYom · 14/04/2026 23:47

He's playing for time, longing it out, hoping he can stay married until the money shows up and he has a chance to get his hands on it.

MrsElijahMikaelson1 · 14/04/2026 23:50

Fuck sake. Just divorce him now. You’re not living as married partners. You’re in a house share with someone you don’t like.

what picture are you giving your kids about what a relationship looks like?

divorce him now and you can have half the house. Leave the rest until the divorce is done and he won’t be able to access it

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.

No. Why should he have a share of inherited wealth he had nothing to do with establishing? Even if doesn't get it, it still goes to the children eventually. Do the maths!

Pldafa · 14/04/2026 23:56

Your marriage is in absolute tatters and he does not care to rectify any of it. Unfortunately I think you need to divorce immediately. You can get a 7yo and two younger ones through it. Easier now than later. You are already running everything on your own. I would sell the family home so there isn’t any fight over it. Your parents currently able to support you through this - emotionally, financially and practically. Don’t wait until your parents are ill and your kids are teens. Get it sorted right away.

His behaviour is absolutely disgraceful. You will be happier and freer without him and definitely do not enter into another relationship for years. Get your dc into a stable and happy home with you.

Busybeemumm · 15/04/2026 00:00

Forget the post nup as that is a Red Herring.

Just get on with divorcing him. He sounds like an emotionally manipulative piece of shit no wonder why your daughter is so anxious. She is on edge wondering if her world is going to change.

Put your DC first and get rid. Being together is not doing them any favours and is abusive to them. What would you tell your daughter if she was with a man like this. Tell yourself the same.

Hayley1256 · 15/04/2026 00:00

This doesn't sound like a good home life for your kids. Divorce him and build a new life for your kids. Do it now so you can stay in the family home if that's what you want as it sounds like he can't buy you out

IdentityCris · 15/04/2026 00:01

It's pointless going for advice on here, you need to get advice from solicitors with expertise in family law and estate planning.

Waterbaby41 · 15/04/2026 00:01

Why on earth did you marry this man? And why not just divorce him - and get him out of the house. The children will survive - and thrive without this nonsense from him. Get a good lawyer quick and get it done. You are doing untold damage to your kids living like this.

PyongyangKipperbang · 15/04/2026 00:03

Divorce now, its the only way before any money comes your way. Frankly I am not sure why you are still prevaricating given the state of your marriage.

And you may well find that your daughter is a lot less anxious once the plaster has been ripped off.

PyongyangKipperbang · 15/04/2026 00:04

Oh and is he sentimental about things or is he manipulative and doesnt want to lose his sugar momma and the nice home she pays for a looks after?

I am sorry lovie, your family is already broken. You are married to a turd and you need to get rid ASAP. First you and your father need some very good estate planning advice immediately. Then you need to find a shit-hot divorce lawyer. Along with that you need to find an excellent and very kind therapist for your eldest child to help them through what will be a challenging time, they will also be ideally placed to counter any horrible manipulation of your child which is pretty much inevitable from the Turd. The divorce lawyer may be able to suggest someone suitable.
Children above a certain age always, always know when there is something wrong, you would be doing your eldest a grave disservice in allowing this hideous not-marriage to continue to wither and die in front of them. Protect the children, protect your inheritance and last but not least, protect yourself.

Your marriage is over OP, you need to get on and finish it legally.
He has completely broken your trust (and your DF's) re signing the post nup, that can never be regained.

Divorce now will protect any inheritance, but more importantly will reduce the amount of harm he is doing to your DC.

He actually sounds as if he has severe MH issues. Scrambled eggs for dinner every night?! Telling his daughter mummy wants to break up the family and it's all her fault?!

I would be amazed if he applied for 50:50 custody, and he'd be unlikely to get it because he does so little for them now.

I know you're worried about the impact of divorce on your DC, but honestly it won't be anything like as bad as growing up in such an extremely dysfunctional home.

Make an appointment with a solicitor and file for divorce asap.

Bear65 · 15/04/2026 00:11

I’m really sorry you’re going through such a difficult time. Given that you may be expecting a significant asset, and your husband is aware and has been involved in discussions about , including past and current conversations around a prenup, it’s important that your father seeks his own independent legal advice. And your should take specific legal advice too.

Some of the suggestions being shared here may not be suitable for your specific situation. I’d strongly recommend not making any sudden decisions or taking steps like starting divorce proceedings until both you and your family have had proper legal guidance.

Good luck

seasaltjar · 15/04/2026 00:12

You could get your daughter into therapy in advance, play therapy etc, your husband might be a lot more careful about what he says to her if he knows she's going to a therapist.

You could also seek advice from a therapist yourself to handle it and what to say in response if he does say it again.

Happiestathome · 15/04/2026 00:14

Leave this man. I’m not one to jump to this, but in this case, it’s my immediate reaction. If he starts involving your children, as you mention he has done previously, you can get support for them. Inform their school so they can support them emotionally and it sounds as though you may also have the means to pay for therapy if required also. I doubt it will be an easy process by the sounds of him, but the short term pain will be worth it for the future of you and the children.

@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.

Honestly- without the money situation just divorce. He sounds like a lazy entitled arse and a shit husband and dad.
fuck him off.

CotswoldsCamilla · 15/04/2026 00:20

You’re focussing on the wrong thing. Right now you don’t have this asset. Now is the time to divorce him.

Fight for the best deal you can get for your children and yourself; don’t offer him the house. Why would you do that, how is that in your best interests or that of your children.

Staying with him isn’t in your children’s best interests. Using them as pawns in the relationship is a sickening move. Think about what kind of relationship you’re modelling for your children with the current status quo or what value he adds to your life if that helps you make divorce more palatable. He can still be a good dad to them if you two are divorced, not that he sounds like one currently.
As PPs have said, consult a family solicitor. Chances are, as the primary caregiver you will stay in the house anyway. Maybe he can move into the rental!

I see far too many flippant LTBs on mumsnet. This time I’d have to agree. If you get out now, the inheritance will be moot. Focus on getting this asshole out of your life; you and your children deserve better.

PrincessofWells · 15/04/2026 00:22

Look at Standish v Standish - very relevant to you providing you are in England or Wales and quite persuasive in Scotland I'd imagine.

But honestly, just divorce him and be happy . . .

DeftWasp · 15/04/2026 00:29

To be quite honest the proposed Post-Nup sounds like it could potentially be in his favour - you are declining a share in the family home for an as yet un-inherited inheritance, inheritances can vaporise, changes in tax rules, care costs, a change of will, a currently successful business failing for unforeseen circumstances. And he'd still get the whole house!!

acorncrush · 15/04/2026 00:30

I think you need to proceed as if he were not going to sign or enter into any new agreement - as this seems likely - and get advice from a lawyer on your position in the two scenarios (1) if you were to divorce and (2) if you were to continue to be married and do nothing. You should find out what the difference would be if you were to divorce in 5 years without this agreement.

Then if pushing him to sign something will lead to a divorce, you know at least what your likely position is financially.

You can’t change the past, you can only try to do what is in your and your children’s best future interests.
