AIBU to insist my share of the house goes to our child?

For context: DP and I have been together for 9 years. First DC due September. Due to be married 2027. DP has a 13 year old DD who was born when he was 18. DP has never had a ‘normal’ relationship with his DD (he has never lived with her) as he worked away when younger and was not in a relationship with the Mother at the time (who was significantly older). He pays maintenance plus ad hoc costs and his parents look after her as GPs would (she stays one night per week at least). Due to moving back to the area, for the last 5 years DP has seen his DD at GPs’ house every week and occasionally takes her and his niece for days out. I am not involved for several reasons, including almost no contact between DP and DD for the first 5 years of our relationship, and the long hours and weekends that I work.

DP owns our current house mortgage free due to an inheritance. I have always paid half of all bills, and half of the odd piece of DIY that has been essential. DP’s Will states that if he dies, 50% of the house would come to me and 50% to his DD. I have never disputed this as it is his inherited money to pass to his DD, and I am grateful that I would also receive 50%.

We have been looking at buying a joint property together for some time now. We agreed in advance that if we were to do this, the money from the sale of the current property would remain separate as DP’s savings, and the new property would be bought with our own savings would be left equally to each other in our Wills. However, once we knew about DC arriving in September, we decided another option (in case a suitable property didn’t come up in time) would be for me to cash buy my share of our current property, and redecorate and get a new bathroom (all cosmetic, we could make do). We would obviously go halves on these costs as it would be half my house.

The issue arises when we were discussing Wills this morning. I used to work in financial planning and so have some understanding. I said that when I buy my share of the current property (or if we found a new property soon), I would need to be added to the house deeds as ‘tenants in common’ rather than ‘joint tenants’. I would then write my Will as a Life Interest Trust ensuring that my share of the property, plus any other assets, would eventually pass to our DC if I were to die first. I suggested DP do something similar to ensure a proportion is guaranteed to go to his DD.

DP immediately said he didn’t like the sound of that, that I was “doing his DD out of money” and that I was being unreasonable. I explained that I am not being unreasonable at all, I would simply be ensuring that my assets eventually return to our DC, and not to his DD as I have no relationship with her and have only seen her a handful of times over the years. I also explained that I can’t really see another option regarding Wills and house deeds. I said if he was not willing to do this, then I would not be buying a joint property with him, nor buying half of the current property from him. If the latter, I would not be contributing to the decoration/new bathroom costs as when DP eventually does sell the property, I would get nothing back. In my previous career, I have seen the implications of Wills not being sorted in advance in situations like this, and children or step-children losing their inheritance, or spouses being left with very little.

Apologies for the long post.

YANBU - I need to forward plan and financially protect myself and our DC.

YABU - I should simply accept that if I were to die first, my assets would join DP’s and would eventually go 50% to his DD.

I may have misunderstood but I wouldn't be happy with any property going to any children, surely the surviving spouse must get it? Where will the other live? Will they be forced to sell so the children receive an inheritance?

I get families are complex and surviving spouse may remarry making it further complex but I would want security if my spouse died.

We had similar when DH assumed that our wills would divide our assets between our kids and his daughter so 1/3 each. He was amazed that I was not fine with leaving any of my share to her. I don't have a relationship with her although he does so why he thought I'd be thrilled to give her a couple of hundred thousand dollars is beyond me.

Thank you, my thoughts entirely.

Have you thought about how this would work in practice if you died? With a lifetime trust your DP would effectively be tied to the property, which he might not want in the event of your death especially if he is young. Many people find it too painful to stay in the same house, upkeep might be too costly on a single income, and life moves on.

Most people use lifetime trusts later in life for this reason, it's not very practical for a younger couple who are unlikely to remain in the home forever (or even if they think they are, life can change).

Thank you. No I haven’t got that far yet.

LettuceAndCarrots · 20/04/2026 10:46

We have done the same, it's quite normal.

DH's half is split three ways between his two DC from his previous relationship and our one DC.

My half all goes to our one DC.

Each person splits their share of the assets between their own children.

Is he planning on changing jobs so he can be a parent to your child? Are you happy in general? There's a bit of a... sadness, to your posts. Sorry if im off base here.

Thank you. Change of job not possible for him unfortunately due to skillset and our location. Family and friends have said they will help with childcare. I am also looking into possibility of going PT. Yes happy in general. DP and I have had a great relationship over the years, have lots of common interests. Tbh I have put off discussions of marriage and kids for a while now as I could sort of see this coming.

You need to stand your ground.

i have seen in blended families the situation that one parent dies and then the other changes their will. This is very common.

stick to your guns.

Thank you

Yes absolutely this. Op's baby is also his baby so if he thought it was unfair to his dc1 before, maybe he shouldn't have fathered another child.

Not sure how he can't understand, don't let him bully you op.

He doesn't seem to have realised that the child you're expecting now is also his child. That is weird. Is the pregnancy unplanned?

Nope planned

And to add, if he does the same you would be tied up in the same way.

Even re: the 50% how does that work when you have children together - does his DD get 50% and you and your shared children get 50% combined. I think the whole thing needs rethinking, and in the long run would be better if he leaves his DD a set amount of cash set aside rather than a share on the marital house.

Thank you. Not sure yet if we stay here and I don’t buy half the house. I also suggested putting money aside in at trust for his DD.

75% to your daughter and 25% to his of the whole house would be a fair outcome as his daughter has the potential to inherit from her maternal family.

Thank you

Does he not realise that half his properties and assets also need to go to YOUR DC now too? that's his DD is effectively getting only half of what she originally was? He has helped make this new baby too.

You're right to stay financially seperate if he cant grasp that hes now going to have 2 children.

His DD should only be receiving 25% of the house. Half his half. Yoyr DC should get 75%
Half his half and all yours

Thank you, I was trying to tell him this.

Because I have felt sorry for him over the years. He was essentially used by an older woman to have a child, and then had to work away due to his job. It would have been logistically impossible for him to care for a small child during the early years. He has tried to make an effort since we moved back to the area as I have said, but still works long hours and works away a lot. This is also partly down to me; I don’t feel entirely comfortable with her as I don’t have a relationship with her .

If you are having a DC together a split of half his money going to you and half going to his DD would be wrong. Surely he should share that half between his 2 DC when new baby is born. He will have 2 DC so leaves his things split between them with you Lifetime use and you will have 1 DC so leaves your half to your DC with him having lifetime use. Surely he can see this is fair. His eldest DC has a mother of her own to leave her things. Hold your ground OP. He is not being fair and could possibly feel guilty for not being around during his eldest DD early years.

Thank you, this is what I was trying to explain to him.

You are being completely fair, and he is not.

Thundertoast · 20/04/2026 10:23

Im surprised that your response to him wasnt:

"Im surprised that you are so bothered about your DD potentially being out of pocket considering you cannot even be bothered to be a proper parent to her"

But then I cant really understand why you would marry and have a child with a man who hadnt moved heaven and earth to be a proper parent to his existing child anyway. So he was NC with her from ages 4 to 9, im going to assume due to issues with mum, but the relationship has been better since she was 9 but she still doesnt live with him in any way, and he hasnt bothered to build up a relationship between you and her?

Because DH eldest DD has mother of her own to leave her things. DH will have 2 DC so needs to split his things between the 2 of them. OP only has 1 DC so want to leave her things to her own DC. It's not hard to understand.

Thanks for setting it out so clearly, it's not something I've had to think about myself so was unsure. (There was no need for the snark at the end though!🤣)

Exactly fair.
