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?

If a mum came on here and said I earn 750,000 and send my ex 12,000 a year for our child that he looks after 24/7, do you think that's fair and reasonable everyone would rip her apart.
The dad wouldn't be called grabby and just after her money 🤦 he'd be called a Saint for 'stepping up' and for putting his sons interests ahead of his own needs

Well, exactly. It's absolutely ludicrous for women to say the child's father's new female partner is just as much of a threat as a mothers new male partner.

They just are not. Purely based on statistics, a child would be much safer with dad's new girlfriend than mum's new boyfriend.

It's ludicrous to suggest otherwise and an affront to women to suggest that they're just as dangerous as a man towards children.

I wasn’t necessarily thinking of criminality, more parenting. So many threads on MN from posters resentful of their partners children by previous relationships and the unfairness that stems from it. I don’t think men have the monopoly on that, and men are often happy to use their new partners as unpaid child care, so they don’t have to worry. Something which again, MN is highly critical of. Until, it seems, the opposite view is more convenient.

OneNeatBlueOrca · 13/08/2025 21:38

The whole post reeks of jealousy from the original poster. She didn't end up married to him with all that money.

Sounds like projection on your part.

Not once has OP expressed regret that they're not together. Just annoyance that her child is living a far, far less privileged life than his half siblings. Any decent man wouldn't want one of his children having a lower quality of life and less opportunities than his others, but since he clearly isn't decent, OP needs to get everything she can out of him.

You’d have a better chance if you ask for an investment in your son’s name or for private school. Otherwise you seem a bit ungrateful.

Why does she have to be grateful? He should pay what the court decides - he’s not doing her a favour by paying maintenance

Whyjustwhy83 · 13/08/2025 21:49

If OP wrote her living cost (not that I'm saying she should) she says rent is 1100 a month o share 550 half sons life cost 275 a month from maintenance paid. Then add 1/4 water, gas,electric other household costs to come out of cm. Then it needs to cover half child after the help op gets from government. Half of clubs clothes travel ect it soon adds up. Before anyone jumps in saying if nearly 1300 a month isn't enough then OP needs to cut back why?

ReplacementBusService · 13/08/2025 21:50

Pashpash24 · 13/08/2025 21:44

Thats a bit uncalled for. I’m jealous because he didn’t marry me 🙈 I’d be lying if I said I wasn’t jealous of his bank balance but im definitely not jealous we didn’t get married lol.

You've got a lot of uncalled for responses here.

You could take him to court for more but have you asked him directly if he would pay for maybe football academy or for private education or whatever you think your son needs?

ScrollingLeaves · 13/08/2025 21:50

iamnotalemon · 13/08/2025 21:10

The OP is getting maintenance, p/t salary and I’m sure UC and is taking home enough to have a ‘healthy savings account’ for her child but wants more maintenance and will probably still only work part time due to the restrictions of ‘football’.

No wonder the country is in a mess.

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.

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

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!!

Amuseaboosh · 13/08/2025 19:25

It's more than enough.

Family Law practitioner here.

Unless your son has severe medical needs above and beyond, it's more than enough.

Your ex has 3 other children to factor in.

Edited

This is really bad advice. It’s not for anyone to decide what’s enough. She needs to go and see a decent lawyer.

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

JustMyView13 · 13/08/2025 21:53

If you want to ask for more, go for it. But nothing is free and everything comes at a cost. What if he says he wants 50:50 access? Then you’ll have the heartache (and expense) of court, and could end up sharing your son. And he might not do this out of love for DS but spite for you.
I think you have to consider the whole package here. Ofc solo parenting DS is tough & expensive. But you don’t have to battle anyone for decisions. You’re in control. Once you start chasing more then you risk losing that control.
And I get it. Why should your son miss out, but I think there’s a balance to be struck.

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.

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?

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.

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.

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

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

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?

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.

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.

DCorMe · 13/08/2025 21:58

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

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.

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

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.
