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?

You can ask him but he’ll probably say no.

JohnofWessex · 13/08/2025 19:17

What are the arrangements for those with earnings over the CMS threshold? Court?

vodkaredbullgirl · 13/08/2025 19:19

Blimey that's good money.

JacquesHarlow · 13/08/2025 19:20

You can apply to the court for a "top up " order @Pashpash24

I'm sorry if this sounds a bit off but why are you not consulting a solicitor when this level of money is involved?!!

Pashpash24 · 13/08/2025 19:20

Yeah it’s called a child maintenance top up order

OK so you know what it is, so why aren't you asking your solicitor for advice or preparing to apply to the courts for it @Pashpash24 ?

Womblingmerrily · 13/08/2025 19:22

I'd say he was paying a fair share of what it costs to raise a child.

Pashpash24 · 13/08/2025 19:22

I felt cheeky if I’m honest. I enquired once about it and the solicitors fees were really high so I just left.

Nomdemare · 13/08/2025 19:23

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

Crikeyalmighty · 13/08/2025 19:24

I would certainly ask but are you at the max now or isn’t there one these days?

RepoTheGeriatricOpera · 13/08/2025 19:24

What does he do for a living?

If its not something self employed, or that he can easily screw you over so he can pay less than he is I would be tempted to take it to court.

The worst that can happen is that you're the same off.

Newmeagain · 13/08/2025 19:25

I am not sure how it works when you are not married. But for high net worth divorces, maintenance would be expected to be a lot more than what the cms can award. So if the parties can’t agree the court would award an appropriate amount having regard to the lifestyle expected etc,

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.

CircuitMaze · 13/08/2025 19:27

You can ask him but that’s a substantial amount of money per month for one child. Many a person on here is barely getting £25/week if that per child, and while that’s nothing to do with your situation sometimes some perspective is needed.

Fuck feeling cheeky.

It's not about you really, it's about your DS. It's money for him and his future.

Your Ex wouldn't miss an extra £10-20k per annum. I say this confidently as someone making about 200k

I'd approach him.about a private arrangement (your son is bigger ge needs more thongs, cost of living etc) and if he wasnt up for it I'd say.thats fine i'll go via court then.

I actually think the amount he is paying right now is disgusting and I'd use google/ AI to help me go to court myself.

Pashpash24 · 13/08/2025 19:28

I’m already at the CMS maximum — they calculate my payments as if he earns £156,000 a year as CMS won’t deal with any income above that; anything over the cap has to be handled through the courts.

paimio · 13/08/2025 19:29

I would ask. I would be in a similar situation if DP and I split and I’d ask and then take him to court if he refused (although I don’t think either of those scenarios are likely I have occasionally thought about it).

FrippEnos · 13/08/2025 19:31

What would you use the extra for?

Absentmindedsmile · 13/08/2025 19:32

This specimen dumped you for another woman when you were pregnant with his child. He then ignored his son for years. He’s disgusting. Take him to court for all you can get. It’s not cheeky, it’s revenge. He can afford it. And .. you and your son are worth it.

I wouldn’t say that if he was a good dad and loved his son and showed it, and you had a good relationship to keep up in front of your child for your child’s sake. But..

THisbackwithavengeance · 13/08/2025 19:32

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.

paimio · 13/08/2025 19:34

I would also think about what might happen if your DC gets to know his half siblings in the future. If they go to private school, go on nice holidays, have nice things you can’t afford, how he might feel a further sense of rejection and unfairness. As a previous PP said, it’s about your DS.

ConfusedSloth · 13/08/2025 19:34

You’re very unlikely to be successful (because it doesn’t cost £2500 per month to raise one child, and it sounds like you’re in receipt of universal credit/child benefit for your DS on top) so you have no need for this for your DS and it would really be considered money for you personally.

Just because the order exists as a concept doesn’t mean you’ll get one or are eligible for one. You risk souring the relationship and costing yourself a bucket in legal fees.

Bluedressandslippers · 13/08/2025 19:35

God; what a sad situation all round. Makes me so angry that fathers can just walk away, poor little boy and well done you for doing it all on your own all these years!

I would ask him to up it to £2000 given he has a salary of £720,000 a year. Even if he paid £2000 a month for ALL his children, he’d still ‘only’ be paying 8k a month which on a £720,000 a year salary (wtf does he do?!) would still be nothing.

That extra £700 a month should cushion you for the future more. I probably wouldn’t ask for any more than that though, at any point in the future unless your DC builds a proper relationship with him and he wants to fund something like private school.

Best of luck, OP!

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

jacks11 · 13/08/2025 19:38

Do you need more to make ends meet? What would you spend it on? If it’s to directly support your son, I’d think it is fine to ask for more- he can only say no. You can then take it to court- I don’t know how much more you would be likely to get so can’t say if it would be worth it in terms of court costs and impact on the already shakey co-parenting relationship? I don’t think he’s treated your son very fairly, so far snd I’d be concerned about the impact of you demanding more money (not saying don’t do it, just saying something to consider). I can’t say whether risking this is an issue or not for you, or what impact it would have on your son if his dad did react badly to demands for more money.

If you are managing ok- i.e. his financial support of your son is sufficient to meet his needs and you want more so you can have a nicer lifestyle or reduce hours/stop working, then I think you are bordering into unreasonable territory. If you didn’t know his income, would you be going to him for more?

You may also store up problems for yourself if you start to rely on a big payment from your ex to support a lifestyle/not working because those payments will stop when he reaches the age of 18.
