CMS payments with 50/50 shared care for kids

139 replies

Hi,

My ex and myself are currently going through separation. We have 2 children under 9 and I was a stay at home mum for the past 8 years. Last year I got back into full-time work and this year we are separating.
We want to share custody and time with kids 50/50, which led me to believe I have no entitlement regarding CMS. I ran the CMS calculator and it told me even with 50/50 shared care for the kids he would still need to pay £457 / month.

He earns triple my salary and said: " if his finances allow he can support me". He thinks he doesn't need to pay anything.
I spoke to a family solicitor and they said legally it would not be enforceable for him to pay any CMS if we share 50/50. He said I should reconsider our 50/50 arrangement, which I don't want as it feels unfair to the kids and him. I want my kids to have equal time with both of us but my ex wants to split child costs 50/50 which is not sustainable for me given I earn 3x less.

Was there anyone in a similar situation and how did you solve this?
What's the legal situation here?

Don’t ruin what sounds like a good coparenting relationship over this, please!

if you can’t afford the school shoes or whatever, just tell him you’re struggling and ask if he can step in.

if you go through CMS, you’ll end up with no CMS and ex will be a lot less willing to help.

Ok, interesting. What's your personal experience?

That poster is full of shit OP.

If it is 50/50, you’re not getting CMS. If you push the issue he will claim child benefit for one child to prove 50/50 so not only will you not get maintenance but you’ll also lose 1 child benefit. It doesn’t matter that he earns too much to claim the money, he will just claim it and not take the money.

icannotlivelaughloveintheseconditions · 20/05/2026 18:04

In order for CMS to not be paid he would have to pay literally 50% of everything - clothes/ trips/dinners / childcare etc and have them 50% of the time including holidays. Even then if he earns significantly more he could still be expected to pay something. I’d try

Interested in this thread?

Then you might like threads about these subjects:

JustAnotherWhinger · 20/05/2026 18:00

This is incorrect. I worked for CMS. 50/50 means no CMS due. Maintenance can be claimed in cases with a huge income discrepancy but that’s through court, not CMS.

There is a very recent thread on here by someone who totally ignored the advice I (and many others) gave and is now massively counting the costs as the advice was correct.

There is no CMS due in cases of shared care.

To her credit, @prolongedaffair has been very good at warning people off going down that path- maybe she'll be along to help OP out.

Yeah it seems really frustrating that he now claims 50/50 time and got to advance his career while I looked after our family. I guess family court would be a next step up considering the history of our arrangements.

The history is irrelevant if you are going for 50/50. It's based on the number of nights the children stay with each parent. At the moment you can't do 50/50 because you're still living together so their nights aren't split between parents.

What is the plan going forward regarding where everyone is going to live. Do you rent or own your home?

MyCandidTiger · 20/05/2026 18:06

MostlyHappyMummy · 20/05/2026 17:59

Stick to 50-50 rigidly so he doesn't just have the children for overnights but pay no child care when he's working and they are with him or do any of their admin
He won't last long as an equal parent as he's never been one
then when they are with you more than 50% of the time you claim cms
until then you'll have to work to your own budget during your 50% of the time

Ok got it. I have been budgeting anyway with not getting any support but then when the CMS calculator ran it told me this essentially:

Scenario 3: 50/50 Equal Custody (182 nights)
Parent earns £50,000, 1 child, true 50/50 arrangement

  • Normal amount: £115.38/week
  • 50% reduction: £57.69
  • Minus £7 per child: £57.69 - £7
  • Final amount: £50.69/week (£220/month

That’s not remotely how it works. CMS don’t get involved in what people pay.

All he has to show (if the OP disputes it) is that he has the children half of all overnights.

He is then responsible for his costs when the children are with him, but not at all when they are with the OP. If the OP books the childcare, for example, and then he refuses to pay for his days then that is a dispute between them that CMS don’t get involved in.

Again it is not correct op. Listen to your lawyer and most posters on here,

Who told you that? They don't care about who pays for what as long as the child is adequately cared for at both houses. It's done on overnights over a year, it doesn't matter whether the nights happen during holidays or term time.

MyCandidTiger · 20/05/2026 17:40

Yeah future me would have not made this decision. But here we are.

I feel for you. Best to focus on building your career (him having 50/50 should help that) and cut your cloth accordingly when it comes to kids' parties, hobbies, gifts etc.

And for anyone else reading, please please please don't give up your career to be a SAHM mom if you're not married or have other financial security.

Rootintootincowgirl · 20/05/2026 18:09

Just to add, unless there’s a safeguarding concern that has been logged by an independent third party (not just you saying it), he’ll probably get 50/50 or thereabouts anyway.

I was primary carer for years, and only work two days a week, and ex behaved appallingly. He still got 40%.

This is wrong and it’s awful people are making stuff up and posting it. If you dint know don’t respond.

No he doesn't and never has done. All he did was work.

We have been separated 3 months now but living in the same house. Currently going through the transfer of equity process.

So literally since last week he is on the school app from the kids, starts making dinners and packs school lunches.

It's just so frustrating. I obviously don't want to go through court and just have to suck it up I think for everyone's mental wellbeing as this will be already hard on the kids. Without any of the financial faff.

Is his job one where 50:50 is realistic? Given he's done so very little up to this point it's not impossible he'll find the reality to be too much work.

MyCandidTiger · 20/05/2026 18:09

ImImmortalNowBabyDoll · 20/05/2026 18:01

If the higher earner earns more than £156k (I think that's the right figure but might be wrong!) you can get a separate order in court which doesn't go through CMS.

Also, CMS is notorious for getting it wrong, so it's quite common in 50:50 for one parent to be ordered to pay but then if they take it to tribunal the receiving parent will be ordered to pay it all back.

Yikes!

This is your best bet…let him create enough rope to hang himself. Less bad blood, similar outcome.

In the time I worked at CMS I cannot recall a single time the calculator was totally accurate.

The gov screen shot someone posted shows there would be nothing due. Your own legal advice has told you nothing is due.

Do not fall into the trap of believing what you want to be correct, rather than what is correct.

At least I put in half the deposit of our current home. So currently we are in the process of equity transfer and I will be buying my own home.

Yeah I think there is no legal standpoint fore really, other than that we might come to an informal agreement. Which I don't think will happen. So there is that 🤷
I did budget all my stuff without initial support anyway, so the CMS amount was a nice day dream to have I guess.

This is always my advice as well.

my ex went to court for 50/50 and got it. Within a year we were back in court and everything was changed as he’d shown he could actually facilitate 50/50.

Yeah makes sense. I honestly just hope for his sake and the kids he will be able to do it all. Like I want us both to be involved and good parents and to be able to talk normally to each other.

This is the best approach op. Go into this amicable don’t make it about the money first and foremost.

Yeah he is buying me out. I can't afford to stay in the house.

WallaceinAnderland · 20/05/2026 18:19

The 50/50 will kick in after you have left the house then.
