AIBU to think my ex should pay more child maintenance when he earns £720k a year?

I’ll try to keep this as short as possible while giving some back story.

I was with my ex-partner for four years. We had a son together, but he walked out before he was born. He saw him a few times as a newborn, but I had asked that he didn’t bring his new partner. My son was six weeks old when he turned up at my door with her, even though I’d said it was too soon.

He took me to court saying she should be allowed to meet him. The court agreed it was too soon and suggested maybe when the baby was older.

Because of that, he told me he would never see his son again. I was devastated and said fine, she can meet him, because I didn’t want him to walk away. But he still refused and never saw him again.

For six years, he had no contact — no visits, no messages, nothing. The only thing he did was pay child maintenance. It was a decent amount (£1,277.50 a month), and I never asked for more.

He went on to have three more children with his now wife. I just got on with life until one day my son came out of school and asked, “I must have a dad, right?” I’d never told him about his father because I didn’t want him to feel abandoned.

When he started asking more questions, I texted his dad to say I was going to tell him the truth — I wasn’t going to raise him on a lie. I’d messaged over the years, even sent photos, and he’d read them on WhatsApp but never replied. So I didn’t expect a response this time either.

Surprisingly, he replied and said maybe it was time to meet. This was when my son was six (he’s now nearly nine). In the last three years, he’s probably met him in person about 10 times. He calls roughly once every 10 days, which I think is poor — it should’ve progressed a lot more by now.

Anyway, to the point. I recently logged into my Child Maintenance account after receiving an unusual notification. It showed his salary: £720,000 a year.

I’ve always been paid £1,277.50 a month because that’s what CMS caps it at. He could earn £1 million a week and I’d still receive that same amount — you have to go to court for any increase.

Would he be able to afford more? Absolutely. I know it’s a decent amount, but he only pays it because that’s the legal minimum CMS tells him to.

I’m self-employed and work part-time so my son can do after-school activities — he’s football mad and trains/plays four times a week. I’m essentially raising him alone; my dad moved 40 miles away, and I have no relationship with my mum. I rarely get a break, but that’s been the reality since the start.

I’ve never asked for an increase, but life is much more expensive now. £1,277 doesn’t go as far as it did six years ago, and £720,000 a year is a huge income.

To put it into perspective — CMS only calculates maintenance on a maximum salary of £156,000 a year. My ex earns over four times that, but I still only get the amount they’d set for £156k — just over 2% of his actual income. Unless I go to court for a “top-up order”, that’s all I’ll ever get.

AIBU to ask for more?

So say you go to court and get £1500. Great, a bit more money to save and allow you to own a property for the rest of your life.

This dilemma is far from the most important matter you should be thi king about. What you should be prioritising is how you'll support yourself in 9 years with a PT cleaning job. Or are you betting on tour son following on his father's steps, become a sport professional and relying on him to support your lifestyle?

Do you have anything saved towards a decent pension in addition to a deposit for a house?

Maintenance goes towards the roof I put over my son’s head, the bills, the clothes on his back all that. My rent alone is £950 a month. This is the point I was trying to make to somebody earlier. When my son was born, my rent was £550 a month. It’s almost doubled. No I’m not absolutely in my arse skint every month but truthfully there are months that are difficult and I completely get that a lot of the UK are in the same boat. I’m super lucky to get what I get of course I am. But when I have a son who’s dad is still doing the absolute bare minimum three years in I find it really frustrating.

I don’t get why all these posters are on your case OP. Where I live a 2 bed flat, no garden, will cost 1200 a month to rent. Even if you were matching the income, it’s hard to see how anyone can see that as luxury money. Yes people survive on less but that’s not your responsibility.

if your son wants to go to university, he will need money. Not unreasonable to expect a well earning parent to contribute more financially when he does nothing to meet his son’s practical needs.

Using ChatGPT to do the maths, and based on the difference between the 156k cap and 720k salary, you could potentially expect a court ordered top up to lead to an increase to £2447 a month. Hardly bankrupting him, and more money for your son, even if you simply put in savings for him for when he’s older.

  • Step 1: Excess income above CMS cap
  • £720,000 − £156,000 = £564,000
  • Step 2: Tariff on excess income (at 2.5%)
  • £564,000 × 0.025 = £14,100/year (~£271/week)
  • Step 3: Add capped CMS amount
  • CMS max = £15,288/year (~£294/week)
  • Plus top-up = £14,100/year (~£271/week)
  • Total ≈ £29,388/year (~£565/week, or ~£2,447/month)

I’d be interested in finding out if his other children are being privately educated and whether he’d fund that instead of paying more via CM

This.

Spirallingdownwards · 13/08/2025 21:50

Your rent went up from £950 to £1100 in two posts!

BTW a lawyer on the thread has already said unless there is a medical need then there is likely to be a top up order. The cap is made at the point where the CMS has decided that double that supports a child well. Unsure why everyone chose to ignore that post

Because it’ not true. I know several people who have top ups ordered by the courts, which are substantially higher than CMS and based on the salary of the absent parent. And I’m wondering why OP had to go through CMS for child maintenance - doesn’t sound like dad was a willing participant at all.

KickHimInTheCrotch · 13/08/2025 22:06

HermioneWeasley · 13/08/2025 19:37

I’d ask whether he’d consider setting up a savings account for your DS so it’s clear he’s not funding you

I agree with this. You don't desperately need the extra money now but kids get more expensive as they get older. Savings to go towards university, driving lessons etc will help give him a leg up when he needs it most.

notenoughcaffeine · 13/08/2025 22:06

Wish I had this problem 😂 I don’t even get £200 a month in CM. And my ex never sees his child.

paimio · 13/08/2025 22:02

Echoing previous comments my understanding is top up orders are not uncommon. Googling the ‘Adjusted Formula Methodology’ will bring up some recent cases, although that formula is for up to £600k. Lots of jealous people on this thread who would no doubt want to do the best for their DC if the situation were reversed.

Hithismyname · 13/08/2025 22:01

That's alot of money. I get £200 I'd happily have that amount for my child. Yes I understand he has alot of money and other children etc but unless you need more for a specific reason then it should be enough unless it isn't? Does he gets everything he needs with that?

Minnie798 · 13/08/2025 22:01

If op, her ex and ds had lived together as a family and ds was at private school, had expensive hobbies etc prior to a separation, then a top up order would surely be granted. But that didn't happen and ds hasn't lost a standard of living he was previously accustomed to, he never had it. So would a top up order even be granted - legal advice is needed. Or op could simply ask ex to set up a savings account for ds so he has money for a house deposit/ uni fees etc in the future.

YANBU to ask for more money

YABU to plead poverty when you choose to work PT as a lifestyle choice. Other single parents work FT.

Where did OP ‘plead poverty’?

No one is disputing that courts issue them. They wouldn’t exist at all if courts didn’t issue them 🙄 trained, qualified lawyers on this thread are simply saying that OP hasn’t given any hint of having any grounds to be awarded one.

I could claim I'm a trained, qualified lawyer on Mumsnet. That doesn't make it true!

WickedElpheba · 13/08/2025 22:00

That's enough of a financial contribution in my opinion. It's some people's full time salary. You choose to work part time but it seems you expect him to fund your lifestyle for you.

TheMAFSfan · 13/08/2025 21:59

I don’t think you’d work part time if you couldn’t afford to. You have ample money from the father, it’s as though you only want more now you’ve seen what he is earning. Why didn’t you bother before? Because his £1200 has allowed you to work part time and spent time with your child, something many working mothers don’t get to do

Clockface222 · 13/08/2025 21:59

Top up orders are pretty standard in cases of high income and I don't see anything wrong with pursuing this for the sake of your child.

You can pay a family solicitor for one or two hours of advice, have them draft a needs schedule detailing the costs of raising the child and explain the process, then represent yourself in hearings. If siblings are getting private education I would be advocating for similar.

northernballer · 13/08/2025 21:44

The bare minimum for his salary, yes, child maintenance is capped so he would pay the same if he earned £200k or £720k.

I grew up with a very rich dad who paid the minimum maintenance possible for his three kids, and often posted the cheque late to fuck with my mother's head. He stopped it completely when we went to Uni on the basis we had moved out, forgetting the fact we needed somewhere to live during the holidays. My mum worked all the hours to provide for us.

Despite that, I don't think other women who get more or don't have to deal with shit behaviour like that should count themselves lucky and not complain, it's not a race to the bottom.

I’m sorry you experienced this.
This OP has made the decision to work PT and claim UC. As well has having healthy savings.
im not sure its comparable to your upbringing.

There has never been/nor will there be a fair system to ensure rich dads pay for all their offspring.

Its the ones that pay fuck all/bankrupt themselves/hide the money who really infuriate me

tangerinemagic · 13/08/2025 21:57

He will pay 45% tax on that plus childcare for his other 3 children. No way his partner would have them all home. Plus mortgage, plus holidays, cost of living and child maintenance. Still very good money but probably he works long hours and sacrifices a lot. To give you an idea I earn £200k a year and pay £60k in London to have two DCs in nursery to work. Plus I’m taxed 40%, country loves fleecing the wealthy.

The country will be in less of a mess with a boy like this whose mum has managed so well on her own, is able to help him with football and a little bit of time after school, and who is now getting his dad to back him up and take an interest.

One less lost boy on the loose looking for a gang or some trouble in our country.

Totally separate issues. The country is in a financial mess. I didn’t say she wasn’t a good mother or commented on her parenting.

Moonnstars · 13/08/2025 21:56

While so far he has been rubbish in actually seeing his son, is there any risk that asking for money could backfire and he instead pushes for 50:50 arrangements in order to avoid paying anything directly to you?

Spirallingdownwards · 13/08/2025 21:56

Labradorlover987 · 13/08/2025 21:51

That’s simply not true - I have a top-up order myself and it’s substantially higher than the flat rate of CMS.

I’d be very wary relying on advice of so called ‘lawyers’ on here - I’ve seen some very questionable advice!!

OK fair enough In any case she should be taking independent legal advice on her own actual situation. The reality is whatever ot costs her its got to be worth it

I was awarded one and neither of my children have medical issues? It was based on his salary alone

planesick · 13/08/2025 21:55

I understand you feel the way you do, but, the contribution is a healthy one when compared to many who receive nothing.
If it were me I think I would be asking for provision, written in stone, to see my child through university if they wanted to go. That would ensure that my child wasn't crippled with debt when they finish uni.
Although, I have no experience in this area or of the courts..so maybe this wouldnt be possible. I don't have any pearls of wisdom for you...just cyber support.

ConfusedSloth · 13/08/2025 21:54

Labradorlover987 · 13/08/2025 21:53

I really doubt that person is a lawyer - you can google case law which shows the courts grant top-up orders

Jamesblonde2 · 13/08/2025 21:54

Assuming you pay equal towards your son, so that’s about £2500 per month. I think that’s easy enough money to fund your son’s life. If he was on £100k would you want more than he pays?

cheeseomelette · 13/08/2025 21:54

I’ve always had a lot more in maintenance than you get. My xh was probably on around £200k and we just agreed it outside cms. For all his awkward shite, he has been decent about paying.

it has made a real difference to our quality of life, topping up my earnings as I progressed my career from scratch again. I’d definitely take advice and pursue this if you can. That amount is nothing to him.
