Financial arrangements moving in together

Looking for advice before I decide where to go next in my relationship. I've been with my partner around 3 years. I have two young kids, he has none. I have my kids half the time, they're with their dad the other half. I currently receive the child benefit and pay for all their child care which is approx £250 a month for after school club, for which I receive universal credit plus a bit extra uc totalling around £300 a month. I work full time and earn around £35k and have no help from family/receive no child maintenance from my ex, currently have a £100k mortgage on my house and have no savings whatsoever. My partner earns at least 3x what i do, comes from a very well off family, has always had help from them (had no student loan, receives birthday and Christmas gifts of a few thousand pounds each year etc), owns his flat outright with no mortgage, and has a large amount of savings, not sure how much but I believe in the region of £250k. We are talking about moving in together and starting, very tentatively, to look for somewhere. For this I would have to sell my house, he wouldn't have to and would rent his flat out. We had a conversation last night which has made me rethink the whole thing and consider ending the relationship and I'm not sure if I'm being unreasonable. He said, and said it was a non negotiable for him, that when we move in together he would expect us to split the costs 50/50. And given where we live and how fast paced it is, if we found the right place he would be happy to cover the costs for 6-12 months while I waited for my house to sell, and then once it had I would pay him back for my share. I know I come with two kids, so there are 3 of me and 1 of him, but AIBU to expect more than this, or is splitting everything 50/50 fair? I am keen to move in as I love him as to my kids, and I want the relationship progress, and it would mean a better home and life for me and the kids, but not at the cost of not losing my own financial safety net and feeling like I wasn't an equal partnership with him, and feel like he should take on some (although not all) of the financial responsibilities of being a step parent despite not being married. Looking for opinions before I decide what to do next with regards to the relationship. I'm happy the way things are currently with us living separately, however I am someone that sees little point of a relationship if living together is not the end goal.

honestly just don’t do it

If you do this and then split up you may never get to buy a house again

I guarantee you that you will be dipping in to your equity ( if you sold your house ) for things in your new house or using it to pay for extra living costs

if you don’t sell it and rent it out
if you split it won’t be easy to get it back under the new renting laws
but as you have a property ( even if rented ) you won’t be able to claim any UC if you need it while waiting to get your house back

also if your kids want to go to uni it will be based on your joint income so they probably won’t get a full loan

Ninerainbows · 07/03/2026 07:57

I understand both sides but I just wouldn't do it anyway. Costs are only going one way and you'd lose some money which he obviously isn't going to replace (e.g. the childcare costs/UC). I think selling your home would be an enormous mistake.

I just think any relationship with such a huge difference in income saying “oh it has to be 50/50” is mean and no fun

I don’t think fun really comes into it when he would be financially covering the cost of 2 children that aren’t his and he’s only known a few years.

goz · 07/03/2026 07:48

His family life, financial help etc are all irrelevant.
I wouldn’t be uprooting your children for a 3 year relationship anyway.
If you did 50/50 sounds fair given you have 2 children that aren’t his. It’s not his role as your boyfriend to provide for your children.

If anything he moves in with you, you split the bills but not the mortgage and that way you have more disposable money to save. Reevaluate after at least a year or two of living together before anyone sells anything.

DaisyChain505 · 07/03/2026 07:47

I definitely see his side. He’ll be one person of a four person household, and by paying 50/50 he’s still over paying for his share technically.

however.

You would be an absolute fool to give up the security you have with your home by selling it and moving in with this man. If the relationship were to fail you’ve be fucked.

ElfAndSafetyBored · 07/03/2026 07:25

I think you need to tell him that as much as you’d love to, you can’t afford to move in with him currently. And then just see how the relationship goes.

I understand about him not being responsible for OPs children but if he loves her and wants a future with her then he needs to factor in she has two children with no help from family or their father. And if he has no compassion for her situation - or for those children’s quality of life or future, then frankly he’s not the man for OP.

Who would want to live with someone they loved who was being pushed towards poverty whilst they rolled in money?

The children spend 50% of their time with their father so he is very involved, it isn't that there is no support from him.

Notquitetheplan · 07/03/2026 07:42

I think you need to cost everything out and sit down with him and show him how much you have each month, with and without benefits and how far it will stretch. Once he sees in black and white that you will be on your bones whilst he will be quids in with his proposal he may be more open to finding a solution. Is it likely that your earning potential will increase?
I’d be very reluctant to give up my home in this situation.

Galliano · 07/03/2026 07:32

I can see his perspective and if this was a male relative of mine this is the position I’d probably be advising, though maybe not to the bills repayment extreme. However OP the risk level sounds far too high for you and your children. You will actually be making yourselves poorer and should the relationship end you’ll potentially be in a less favourable place housing wise as no guarantee you can buy the equivalent plus you’ll have had the hits of moving costs - solicitors, sdlt etc

I just think any relationship with such a huge difference in income saying “oh it has to be 50/50” is mean and no fun

But you could also argue that 50:50 is still him contributing “more” because he’ll be 1 out of the 4 people in the house. He’s not the reason they’ll need more bedrooms, for example.

But, as I said upthread, even though I don’t think he’s being unreasonable, I wouldn’t make myself financially worse off if I was the OP.

Catza · 07/03/2026 07:31

Neither of you are wrong but I don't see how to make this situation work so you simply can't afford to live together. You don't have to break up with him over it, though.
I would elect to keep my own house at all costs. I know all too well how quicky a relationship can break down and ending up homeless with two kids is no fun at all.

pencilcaseandcabbage · 07/03/2026 07:22

I'm afraid this screams disaster in waiting. You would be making yourself financially vulnerable for a man not ready or willing to marry you. At the moment you and your children have a home you own and are gradually paying off. You can afford your life, your mortgage and you are building security for you and your children. If you move in with this man you are giving up your home and also losing money, such that you will potentially be worse off by £100s a month. You will no longer be in a position to continue to build that security. You will be paying more for a life you can't afford (but he can), and are putting the security of you and your children entirely in his hands, with zero commitment from him. If it's 50:50 on everything, does that include socialising and holidays? How will you afford these? Will he be happy if you can no longer do things together because you are so much worse off? If you split, can he buy you out?

If this is non-negotiable from him, it says he is inflexible, unwilling to discuss, and unable to realise or appreciate the sacrifice you are making. Because it is a sacrifice. You are giving up a lot and it sounds like he doesn't see that. This does not sound like a partnership.

NewYearNewMee · 07/03/2026 07:15

I’m really on the fence - I think it’s obvious you bring more costs to the relationship, there’s 3 of you and 1 of him! Your children are also likely to up the bills and require more rooms than potentially he would need if buying again on his own, they’re also likely to cost more as they get older. So realistically you and your DC are 75%, him 25% so he’d already be subbing you on 50/50.

However if he’s in a relationship with you, knows you have DC, knows about the earning disparity and still wants you to move in together I find it odd that he hasn’t considered the change in financial circumstances that would happen (e.g you losing child benefit and paying a higher mortgage). It seems like perhaps he doesn’t want to pay for your DC - which is totally within his rights - but he must surely understand that’s a barrier to living together?

I would remember that earning 3x your salary doesn’t automatically mean he takes home 3x your wage though. It sounds like he has a lot of savings, mortgage free flat etc - he’s possibly worried that he’s going to be taken advantage of financially and is being seen as a bit of a golden goose? Especially if he has family money too.

Whaleandsnail6 · 07/03/2026 07:12

Don't move in

I can see both points of view ..you will be financially disadvantaged due to loosing benefits and having to sell your home, which gives you less security

However, from his point of view, if you don't do 50/50 he is paying more of the costs of living when you are not married and your children are not his financial responsibility

You don't need to move in together.

Snorlaxo · 07/03/2026 07:11

Neither of you are being unreasonable.

If you go 50/50 then he is subsidizing your kids as you’ll be living in a bigger house than he requires and your kids will get older and eat as much as an adult. He is right not to jump into financing your kids when their dad doesn’t.

Yanbu to want cohabitation and worry that you could be worse off financially. Even if he agreed to live in an area where you could afford 50% of the costs, he will be saving a lot of money and receiving gifts from his family they could cause you resentment. I suspect that he might be anti-marriage to protect his assets too if that’s something that you’d want?

Ophir · 07/03/2026 07:09

I’m with him really. There’s no way I’d make myself financially responsible for another adult and their DC.

Morepositivemum · 07/03/2026 07:02

Op is it a bigger home or is it that the cost of houses has gone up?

ACynicalDad · 07/03/2026 07:02

I think he needs to go a bit further, I’d say put in in proportion to what you both earn. If he doesn’t want to help more than equal shares and is happy to have loads whilst you struggle it doesn’t sound particularly loving relationship to me. Also make sure you have a written plan for accommodation if you break up. I’d rather he paid for the home and kept all money if you break up and you keep and rent yours out. Lost benefits also need to be part of the conversation, they are there for a reason, that you e salary is not enough.

jacks11 · 07/03/2026 07:01

Your proportion of household costs is 75%, but you want to cover less than 50% of that? When you consider that you are probably going to buy a bigger home than he would need because of the children, I can see why he might baulk at your suggestion he pay substantially more of household costs. I’d say he is not being unreasonable to decline to support you and your children financially to that extent when he is not married to you. It’s simply not a wise decision for a financially stable person to make. If we flipped genders and a man with children was asking his female partner to do this (put herself in a financially worse off position by taking on the bulk of the financial burden for 2 children who are not hers), she’d be strongly advised not to.

What proportion of the costs you think he should pay?

If you did pay less and then split, would you be expecting 50% of the value of the property too?

On the other hand, I would say that it is also reasonable for you to conclude that you can’t afford to move in with him at the moment. Are there any compromises to be made- e.g. move to a cheaper area than planned? If not, then I think you just have to be upfront that the move is just not a financially wise thing for you to do right now.

I don’t know that that necessarily means you have to end your relationship, but that’s entirely up to you.

TeenagersAngst · 07/03/2026 06:55

Presumably because he can afford his share of the new house deposit without selling anything whereas OP can’t.

ah, yes, of course, thanks.

TeenagersAngst · 07/03/2026 06:55

Ophir · 07/03/2026 06:02

Why do you have to sell your home and he keeps his?

It’s good that you’re discussing this before you make a big move. But I think I’d keep separate homes until your dc are older

PurpleCoo · 07/03/2026 06:49

I would say splitting bills 50/50 is generous from his point of view considering you have children that are an additional expense and not his responsibility.

However, I can also see how things will be more difficult for you financially, and you need to look after your own and your children's interests.

Why would you not get child benefit? They take your partner's income into consideration? That seems wrong when the children aren't anything to do with him and not his financial responsibility

I was a single parent and took the decision to never marry and I never want to live with a partner. I am in a long term relationship but we have our own space and pay our own way. It's much easier, but if people feel they need to live together fair enough, but I think it does make things a lot more complicated when children are involved.

Yes. The government sees a partner who has nothing to do biologically with the children as being part of the provider for the children and thus benefits (including child benefit if the household income is above a certain threshold) are stopped.

frozendaisy · 07/03/2026 06:51

Nope I wouldn’t do this

He is well off and it seems like he would also like to get another half a house on the back of your and your children’s sacrifice

Your financial responsibilities are to your children only
They are only going to get more expensive

When I am I first moved in together he earned double what I did - so he paid rent and I paid bills about a 2/3 1/3 split
He also paid the bulk of going out costs
Because he loved me, us, money was to enable us to live not some excel worked out asset split grabby exercise

Stay as you are for now @Rainbowcat88

If your boyfriend loves you and the kids he needs to show it and that does mean, in my eyes, financially as well.

He isn’t asking you to get married is he? He is asking you to potentially have less money to live in a bigger house he gets the benefit from. And say you did split up? Right now it’s easy, but if your only asset is tied up with him it could be a painful process, plus house prices are flat at the moment, could go down, interest rates won’t fall. With inflation house prices are effectively dropping.

Right now you and your children have stable, financial, independent security. You need to keep this.

If he wants a bigger house he has plenty of cash and a flat to get one.

Fiftyandme · 07/03/2026 06:51

I would never ever ever put myself in this situation ever again. You’re making a big mistake and making yourself vulnerable.

Have him move into yours if you want to live together.

No decent man would want to put you in this position.
