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.

I think you need to hope for the best, plan for the worst - the worst being that he's planning to put off the post nup until you come into the money and then divorce you for 50% (I'm assuming the asset you'll come into is significantly more than the 900k in the house). Talk to a solicitor and a financial advisor and find out what you can do to protect yourself.

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.

purpleme12 · 14/04/2026 22:07

Well I'm not sure what I can say really
Of course there was always the chance he wouldn't sign it

I hope things get better whatever happens

Traveltart · 14/04/2026 22:08

Your dad needs legal advice from estate planners. Can he write the business into trust?

AbzMoz · 14/04/2026 22:08

Hindsight is 20/20 but if this was so vital to you or your family (dad) why did you proceed with the marriage?

at this point I’d stop having conversations with DH and get robust legal advice. tell your father to just keep face with DH. I am not a lawyer but someone smarter than me might suggest trust for you/ the kids if the business hasn’t been handed over yet.

I don’t see why you’d throw everything at your marriage when you don’t trust your husband to keep his word and he is incapable of having a proper conversation on important topics but each to their own.

44PumpLane · 14/04/2026 22:08

I genuinely believe in this circumstance that you need to initiate divorce proceedings and follow through. You don't have to leave him, you don't have to dissolve your relationship (although that may be the outcome realistically) but I do think that you need to start divorce proceedings.

The only other thing I can think of is could you discuss with a solicitor the prospect of putting the inheritance directly into trust for you (ie your family putting into a trust) in a way that would protect it from forming part of your estate in the event of divorce?

PiglingBlandings · 14/04/2026 22:10

It would help to know where you live - England Scotland treat different things differently.

honestly, I would calmly file for divorce and that should get his attention. You have a 20 week enforced cooling off period and he can sign during that. Or not. Then you know what sort of man you married, frankly.

Simple, but not easy. Don’t engage with rows or shouting, just say calmly you’ve been stone walled enough and that’s what has led to this point. You’ve been open to communication on this for however long and being told you’ll be locked out is not a response from someone you care to remain married to.

Savvysix1984 · 14/04/2026 22:12

You shouldn’t have married him if these issues were so important. I prob wouldn’t sign either at this stage. The best you can hope for is if you divorce there’s a settlement he’s happy with.

LaylaN · 14/04/2026 22:12

Grim, it’s the kids I feel sorry for. Money ahead of them.

Tableforjoan · 14/04/2026 22:13

If you want to protect your inheritance you must divorce him before you get it.

Winter2020 · 14/04/2026 22:13

File for divorce.
This does not sound like a happy marriage regardless of inheritance issues.

I'm guessing it's important to protect the business because people/family members would be out of a job if it ends up sold off and broken up?

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.

Your DH would be a fool to sign this now. Perhaps divorce now, before your interest in these assets materialises fully, or accept that your DH will have a legal right to 50% of the inheritance if you divorce later.

OneNewEagle · 14/04/2026 22:15

File for divorce. Enjoy your divorce where you don’t have a husband behaving like this and put yourself and your DC first. I would never have married him in the first place, but I have never married due to trust issues.

KellsBells7 · 14/04/2026 22:16

If your marriage isn’t good, why not divorce? Not for leverage to get the post nup signed, but because you are unhappy.

namethisbird · 14/04/2026 22:17

divorce, divorce, divorce before it’s too late

if you are not in a great place just get rid and then there is no requirement for a post nup as from what I can gage from your post you haven’t inherited anything as of yet. Why on earth do you want to be married to this man?

RoseField1 · 14/04/2026 22:17

I can't see why you would want to stay with a man who treats you like this, so maybe time to cut your losses, divorce (don't give him your whole house) and get your personal finances straight afterwards.

Trusttheawesome · 14/04/2026 22:18

You should never have got married if you wanted to keep finances separate. Even with a post nup, they’re not binding.

If you inherit, and it isn’t in trust, then he can get his share if you divorce. So you shouldn’t have married. It is a contract.

MyMonthlyNameChange · 14/04/2026 22:18

Do you have siblings OP? Are they married? How have they done it?

I don’t really understand why if it’s so very important now, you went ahead and got married in the first place without it signed. I think you can interpret from him loud and clear that he has no intention of signing it and likely never did.

Why do you want to try and remain married when the marriage sounds awful frankly. And why are you the main breadwinner? Does he do all the childcare, housework and life admin, or does he leave that all to you and just sit in his office waiting until he can cash in?

Trusttheawesome · 14/04/2026 22:19

If the marriage is on the rocks now then maybe it is time to call it a day and divorce, before there is any inheritance. Split your assets now, he won’t get the whole house. And make sure to complete the financial planning order, don’t leave it or he can come back later.

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

Country???

If the money goes into a sole named account og yours, there is a stronger argument its not joint money but youd have to be careful also on what you spent it on. In Scotland its easier to be discounted but ultimately divorce with a clean break order is your only hope.

I've read a few stories in my time where the Pre/Post nup has been thrown out in court, all the other person has to say is that it signed under duress.

graywingeddoor · 14/04/2026 22:21

Divorce now and not when the inheritance happens?

true, but this does kick the can down the road and allow you to stay married (if you want to) without the risk of your entire inheritance becoming a marital asset. It’s not ideal but it might do for now?

Are you in England, @mamato3rascals?

Please see a solicitor asap with your dad, and book a long appointment.
