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.

Get proper legal advice - lifetime trusts can make allowances for selling and moving. We have done this and my parents did it for myself siblings and our children

He thinks I should just leave my assets to him and then 50/50 to our DC and his DD. I explained that he would then essentially be “doing our DC out of money”.

He's completely disregarding your pov here! You are not the mother of his first child yet he wants you to pretend you are financially.

This is no different to all the posts of men expecting the step mothers of their children to treat the sdcs just like their own.

So convenient for men to get new mothers for their children like this 🙄

In order to be in an equal partnership, whether here or in a new property, we would need to be equal on house ownership. As I have said, his current Will leaves 50% to his DD, so I wouldn’t “take it all”.

I earn more than him, and am quite capable of paying for repairs, I just do not want to as it is not currently my property. Comments about him “being a man, let him pay” are odd.

If you are going to pay 50/50, with his arrangement and views he will take from yours and give it entirely to his daughter only. He is bizarre

dontmalbeconme · 20/04/2026 16:46

Are you buying your half at full market value?

If so, then I think you are correct. He could put the 50% of house value that you pay him into a trust for his DD if he feels like it.

HHHMMM · 20/04/2026 18:35

I don’t understand your threats to him of not buying the house together if he doesn’t agree to your terms. Does he actually need to sell the house? What are your options if he sticks to his position and just lives in mortgage-free house albeit without a new bathroom?

Ultimately it doesn’t matter how many strangers here agree that your position is very fair.

ArtAngel · 20/04/2026 19:05

Does he understand that he can make a matching provision but leave his share of the house to his Dc? Including his eldest?

Do a little diagram for him , showing the shared out money.

She’s not ‘threatening’ him, she’s told him that what he’s proposing doesn’t work for her, and is not something she’s prepared to proceed with.

Absolutely, very reasonable to tell him this. Then his choice could be to stay with the current status quo. Doesn’t really lead to the conflict resolution. What is her next move then? Leaving him while pregnant? Getting a house on her own?

I am not telling that OP is unreasonable, but perhaps the conversations should have been done more delicately and not that radical.

He's a partner and not a husband? I say do not play house with someone who isn't a legal spouse.

You are right to protect your assets for your children and not rely on their Father to remain focussed on safe keeping of your assets.

our very close friend’s ‘step mother’ gave away all personal items belonging to friend’s mother when she moved in with the father. His cousin told us SM was even wearing some of the woman’s clothing. Our friend couldn’t even get her Father’s wedding ring, as it was used for his 2nd wedding and the SM claimed ownership of it after his death.

SM went into another defacto relationship and did similar there too. Not sure what hidden talents she has, but there’s two men for you as an example who thought with the wrong head..🤨

YANBU, when the time comes your DD should get your entire 50% of the property plus half of Dad's 50%. Other child would then get half of Dad's 50%.

I am not a financial person so maybe don't understand, but what would the problem be with both children each inheriting 50% of the property? Whether or not you have a relationship with SDC, you are a blended family, so I don't understand the problem?

one child has 2 parents each have 50% of the property, 2nd child has one parent with 50 % of this property.
1st = 50% (full mother's part)+ 25%( half father's)
2nd = 25% father's part and whatever the other parent (second child has its own mother) might have
