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?

Funny, when I was a single mum, working FT because working PT was not an option....because I got 0 maintenance for 2 children, I managed to find ways so my kids could still do activities after school. It really wasn't that hard to ask other parents if they'd be interested in taking my kids from school and I would bring their back home and parents were very happy with that option.

You can twist as you want but the football is nothing more than an excuse. In between the maintenance and UC, I suspect you get much more than the average single mother working FT. Yet, you think you should get even more from him.

Don't forget that in 10 years time, you'll have no maintenance and no or very little UC coming in, oh and I guess a very small pension fund if any. 10 years go by very quickly. I'd focus on preparing for the future rather than trying to get even more from him.

So because you had a difficult time, so should everyone else?

Labradorlover987 · 13/08/2025 22:25

That’s simply not true though - what do you think a ‘top-up’ order is?

It's where a court can but is not obliged to and often will not order that an additional amount of CMS is paid.

What do you think it is? And why do you think it disproves anything I said?

Starlight7080 · 13/08/2025 22:29

I think its a tricky situation as obviously his other children will be benefiting from his money more.
Also although not for several years you have to plan for when the money stops when your child is 18 . Like you have said everything keeps going up in price so at that point you won't have that money to help will bills and such.
Maybe he will shock you and when he goes to secondary school help some more with costs .

I know what it is - I am in receipt of one. None of my children have medical issues and it was solely decided on my ex partner’s income.

PamIsAVolleyballChamp · 13/08/2025 21:13

And he's paying nearly £1300 a month for this, equal to some.peoples salaries. To fund whole families!

Edited

And that (less than) £1300 is 0.17% of his annual salary.

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.

Indeed and I got the grand total of £0
I think you have a good deal OP

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.

To end your comments about her with …,
‘no wonder the country is in a mess’ came across as a comment of resentment about her.

Enrichetta · 13/08/2025 22:38

@Pashpash24 - you’re not going to get valid answers here - you need to seek legal advice from a family solicitor with experience in dealing with cases that involve high net worth individuals.

My own layperson suggestion would be to approach this from a “paying for independent schooling for his son” angle as this may resonate with him more than a perception of you wanting to “feather your nest, go on holidays” etc.

Hotflushesandchilblains · 13/08/2025 22:38

The CMS system is not fit for purpose.

Congratulations on your achievements, you should be very proud

Booboobagins · 13/08/2025 22:45

You can't work full time because you look after his child and for that you get £1.2k?

Go to court seek more money.

Good luck.

Pashpash24 · 13/08/2025 20:43

Why are you taking such an angry tone?

“Because that's the third time you've pretended not to hear the question.”

I’m sorry i didn’t seen it before the post has a million comments.

So his current schedule after school is:

Monday - football development at an academy at 5:45pm
Tuesday - swimming lessons at 4:30pm
Wednesday - off
Thursday - Football training for his team he plays for at 6pm
Friday- football development again at 4:30pm
Satursay - off
Sunday - Football game for his team

L.M.A.O

You "can't" work to support your own child because you've chosen 4.30pm swimming lessons on a Tuesday. And ohhh he just has to do a fourth football session on a Friday at 4.30pm too.

Is that really what you tell yourself, to stomach that the state and your ex boyfriend pay more for your own child than you choose too...and your first port of call for more money is to ask someone else to hand you even more.

Shameful.

I just don’t understand this mentality - just because you got £0 means everyone else has to be grateful for whatever they get?

No no, just calling out OP for what she very clearly is.

Making lame excuses not to work. Wondering how she can get more cash from an ex boyfriend who's contributions already far surpasses what she contributes.

123456Sh00tingStars · 13/08/2025 22:54

The father works (because he has people facilitating this)
1x phone call every 10 days
The mother is doing 99% of the parental work load physically & emotionally.

I do not know what career the father works in, will he still be working in 10 years time or will he be retired ?

The ex-boyfriend is also the father of the child.
And she’s not wondering how to get more money out of him - she’s wondering if his contributions are fair, given he earns a large amount over what CMS takes into account.

How do you calculate that her contributions are less than his? She has raised the child alone for 9 years. She worked full
time until a year or two ago. Then ran a cafe, so she’s only been working part-time for a little while. She may well bring in £1200 a month from her cleaning job.

I expect OP spends a high proportion of her income on her son. The father contributes 0.17% of his salary.

usedtobeaylis · 13/08/2025 22:59

I think you should ask. You're making significant economic sacrifices for your son's benefit and doing so on your own.

That given the current situation, I suspect he didn't want with OP, but has zero choice if she chose to keep the pregnancy, so now does what he legally has too.

He's a doting father to 3DC he had almost immediately after.

CopperWhite · 13/08/2025 19:44

You receive more than enough to cover your ex’s share of your son’s costs. Your child is not there for you to profit from. You are being greedy.

Eh?! Have we read the same Op, he’s on 720,000 and gives a pitiful amount, this is HIS child.

Switcher · 13/08/2025 23:07

Seems kind of an ok situation to me. I wouldn't mess with it. He obviously doesn't want to help or be that involved in any other way. Like PPs I'd maybe discuss school fees with him for secondary.

Oh of course, you’re the wife and that’s how you know about his parenting of his other children and are so protective of his money.

Otherwise, there’s just no explanation for justifying a man being a shit father to one of his kids and a great father to the others.
