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?

I wouldn't have wanted a new woman visiting my baby either at 6 weeks old, do you not remember the post birth hormones? And if you think that's enough justification for him to completely abandon his child then that just shows what kind of immoral person you are.

He didn't want the child.

He's not abandoned anything or anyone.

He just didn't visit a child he was clear he didn't want but the mother decided to have, knowing this.

Are you one of these women that think anyone who impregnates you is now duty bound to fund you and your child for life, and should be forced raise the child they didn't want but you decided they would be getting regardless. And if they don't they're a "shit father."

Women need to take accountability that with the sole control over whether a child is born, comes the absolute responsibility of the circumstances you choose for that child to be born in too. If those circumstances turn out to be shit for the child, grow up and look in the mirror instead of anyone else to deflect on too.

What did he abandon? OP always lived alone in her rental as she still does. He lived somewhere else. They had some kind of interaction for 4yrs. Perhaps they would describe that interaction very differently.

She falls pregnant. He doesn't want to be with her or raise a child with her. He ends their relationship/friends with benefits/weekend hook ups/who knows what the situation was. She decides to keep the pregnancy as a single woman without the father. Both have done nothing wrong. Both are entitled not to want a baby.

Where's the abandonment? OP assessed the situation and chose to become a single mother. That's her prerogative. She's not abandoned.

If OP chose she wasn't having the baby, would she have abandoned it? Of course not. But because she can choose to have it, suddenly the other party has abandoned her. Again, of course not.

She's not to blame for being abandoned because she wasn't. She is responsible for choosing to have a child without a present father when she equally could have chosen not too, but that's not right or wrong, that's just simply the choice she made.

I have an old acquaintance who did exactly this.

I say acquaintance, because she is an old work colleague.She was a secretary there.

She had a friends with benefits precisely as this original poster described. It was obvious they were neve in a relationship, it was random, hook up here and there.

She got pregnant though, and as she was in her late thirties, she let slip to me that she had stopped taking her pill and she actually had feelings for him. Last chance saloon to have a baby.

I do also wonder about how the OPs kid suddenly came to existence when you re not in a relationship and you know that. Surely you use bombproof contraception.

He didn't stand by my old colleague as they weren't in a relationship.It was never agreed they were in a relationship.

Basically, he's gone, she didn't see him for dust. I'll hand it to her, though she's working to support the child as best she can. But she also has a long term health condition, which has worsened and their lives are quite chaotic, as she's frequently unwell and too ill to work.

She doesn't dare contact her ex or make a claim to child maintenance. In case he comes and demands contact with the child and she doesn't want that.

She can't really claim abandonment, either given her choices.

I get it, of course.She was vulnerable and didn't want it thrown in her face that her ex never had a relationship with her but was quite happy to start a relationship with someone else.

Of course she shouldn't have had to have her in her home.

Any kind of compromise would be when the baby's older and you are able to take him out.He can see the girlfriend, but I don't want to see her.

it was a no, no no way, never and in that order. Then when he did go, she changed her mind and try to backtrack.

Exactly this.

I think she assumed a baby would increase her status and cement her place in his life. Banking on that he'd change his mind when baby was born and suddenly develop feelings for OP and her baby.

She won't be the first, not last. And sometimes that plan does work, for a while anyway.

But she needs to be honest with herself, and accept her part in all this, for what is going to be little fun for her child. It will be shit to see the result of 3 children born of a loving marriage in a successful and loving household. It's none of their fault that OP chose to keep a pregnancy ten years ago when the man didn't want the child with her. You can't play the shit father card, because he's clearly very good with the children he chose to have. It's just too uncomfortable to be truthful and say "only I wanted the pregnancy, and it's both parties right to not want keep every single pregnancy they might have conceived, for all manner of reasons. So actually, no one did anything wrong, your life is different because of the circumstances I chose for you"

I sometimes wonder if my old work colleague thinks about this.

It's a taboo subject with her.We just don't mention it. Her childs parentage that is.

He completely legged it, and she never even claimed maintenance. It's because she doesn't want him having anything to do with the kid now.

I wonder if he has a partner wife or more children. He's about the same age as the OPs son just a little bit younger.

Apparently he's never asked about his dad, but he's bound to at some point.Although she's convinced herself, he's completely find just with her and doesn't even think about it on the rare occasions, she does mention it.

Yep.

Of course lots of kids are fine from single parent families. And lots aren't.

I guess when you grow up with just mum (who wanted you) your only frame of reference is that a parent should dote on you. So by that train of logic if dad didn't want you he's horrible and has abandoned you, not that dad was perfectly reasonable in not wanting to keep the pregnancy with mum. And then trying to reconcile dad simultaneously being the doting parent to three other children.

The difference is, the children that mum doesn't want, simply never happen. So mums never have to answer to a child that they perfectly reasonably didn't want to have. Dad's have too. When all they've done is made the same decision as the mum did.

Is it only women who can decide a conception is unwanted? An unwanted pregnancy isn't "nasty". Ask the millions of women each year who decide just that.

"It" is simply gender neutral. A generic baby. Him. Her. It. Them. Take your pick. Somewhat clutching at straws to find things to be outraged by now... Although seemingly not at choosing to have a child with someone who states from the start they won't be involved, then crying "abandonment" because turns out it's shit for the child...

Definitely not outraged by a stranger on the internet, I just think your responses are horrible and extremely angry about something that’s not really present in the posts. The child isn’t generic, he’s a boy - she said that from the start.

The father left her when she became pregnant four years into a relationship, but somehow you’re making him the victim. i don’t think she’s said anything about being abandoned.

He wasn’t ‘a friend with benefits’ and the OP never said any such thing.

DrinkFeckArseBrick · 15/08/2025 13:05

I think a lot of posters are getting sidetracked. Fundamentally do we think it's OK that one parent pays most of their income on their child or towards their child (eg in housing, or a reduction in salary to keep a job with flexible hours) while the other parent pays less than 5% of their salary towards their child, meaning that their shared child has a significantly lower standard of living than:

  • They would have had, if their parents hadn't split
  • Their half siblings have
When it could relatively easily be changed by the non resident parent, without any real impact to them or their new family

I personally don't think this is ok, and its pretty low to be suggesting the OP is greedy for wanting better for her son. And when it's the other way around, and posters are talking about their partner paying maintenance to their ex, everyone always says good parents pay more than the absolute minimum and pay their share of extras.

HopscotchBanana · 15/08/2025 08:37

OP was with the man for four years and he walked out when she was pregnant, yet somehow you’re making her out to be some opportunist.

Perhaps some degree of opportunism. More likely just trying to force something. People generally don't have serious relationships for 4yrs and not make any steps to at least move in together. He certainly didn't see her as serious. Because he's shown his actions when he is. His wife, he had met, married and had 3 children in not much more that the same space of time than OP states their relationship was.

If you asked him, was it a 4yr relationship, or was OP someone he was casually dating on and off perhaps amongst others over a few years. I think it's clear that he was what OP wanted, and I think she built up visions of one day a proper relationship, moving in, a family, because they were sleeping together. I think we've all been guilty of convincing ourselves of things are fine and real when we don't want the alternative to be true.

He didn't walk out on anything because there wasn't anything to walk out on. Had she made the same decision as him and decided the baby wasn't wanted, it would be a total non event. Two people that don't live together, no longer sleeping together. No division of assets. No unmerging of families. No moving out and starting again. Just a boyfriend ending it with his girlfriend.

All those things remain the same, except OP found she was pregnant. There seems to be some weird expectation that he should suddenly want her child and raise it and he's a "shit" for not wanting either. If she's decided the same, is she a "shit?" No. Does he pay the maximum amount CMS can grant, every month, without fail? Yes. Funding her ability to choose to work part time. Yes.

After seeing the reality of deciding to have a child that only one parent wants, and having played silly buggers with contact when he was born because she was jealous of his wife, her son starts asking for his dad, so she contacts him, and fair play he agrees to some contact. And after all this, she's clocked her ex's pay packet some ten years after the last time she was anything to do with him. And her great idea is to go after him for even more cash.

You’re really reaching here just to continue your diatribe.

None of us know the circumstances of the relationship - OP says he ‘walked out’ which most would read as living together. You’ve no idea how long it was before he married the other woman or how long before they had children. The OP might well have discussed children with the father, got pregnant and then he left without warning (likely because he was shagging the other woman by then). So OP should have aborted a baby that she wanted because he left? And not doing that makes her an opportunist. Ok then.

And I really don’t understand this bizarre thing about jealousy. Picture it, a man you love has left without warning when you tell him you’re having a baby. He visits a few times, seems interested but then asks to bring his new girlfriend. You’re six weeks post-partum. Who in their right mind would agree to that? Who in their right mind would suggest it? What kind of woman would think it appropriate to visit her new boyfriend’s baby so soon? Or shack up with a man with a new baby for that matter?

You seem heavily invested in the version of this that paints him and the now wife as perfect, and willing to make up information to suit that. Try telling yourself the story a different way, see what happens.

Crushed23 · 15/08/2025 13:16

I haven’t RTFT and I don’t know the ins and outs of family law, but I’d be concerned about working P/T because I’m receiving £1300/months in CMS. This won’t be forever (maybe another 10 years?) and soon you won’t have access to your ex’s salary at all. You need to think longterm about developing a career and building up a pension, because once your son is an adult, CMS and child benefit and any other child-related payments will stop and you will have to fend for yourself.

Crushed23 · 15/08/2025 13:20

I’ve just seen that your ex plays sport for a living. In that case, as has been mentioned, he has a different pay trajectory than in most jobs. His pay will peak in his youth, perhaps in his 30s, then it will drop significantly. You can go after more money now, sure, but the additional payment might be short-lived if he finishes a contract and signs a much lower paying one. Just something to think about.

MC846 · 15/08/2025 13:24

Tbh I don't think he should pay you more, £1,200 a month as a 50% contribution to the raising of one child is a decent amount, it's not really your business what he earns as long as he's helping to provide for his son and he is at a good rate 🤷‍♀️

OP has completely ignored this and just focused on the fact that she can't work more because of her child. One 9 year old...

Her child is nine. Therefore, she has less than nine years until she loses her exes maintenance and all of her child related benefits. She's burying her head in the sand and looking for ways to get more money out of her ex rather than worrying about herself.

Her ex is obliged to support the child until he's an adult.He's not not obliged to support her until she dies. She's got to make some kind of plan for having a decent income for herself but she's just ignoring all of this.

Well, he split when she was pregnant.So it's suggests that it wasn't a strong, a relationship as she thought. They clearly hadn't planned children.And after four years weren't even married.

Whyjustwhy83 · 15/08/2025 14:28

They were together 4yrs so not sure how he never had a relationship with her.

What OP called a 4yr relationship, I suspect he would call different. They didn't even live together. She was in a £550 a month rental. Which has increased to £950 a month rental or an £1100 a month rental as she's changed the figure within 2 posts...

I imagine the period of time since they first slept together and the last time they slept together was 4yrs, but they certainly weren't building a future or home together. 4 years is quite a time (apart from divorcees who are adamant they'll never live with anyone again, and single parents who don't want to move anyone in with their child) to go nowhere in a genuine relationship.

There are two examples in the last couple of pages about women who were sleeping with men they were infatuated with, and the men very clearly didn't think there was any relationship. It's what the women called it though.

DaisyChain505 · 15/08/2025 14:43

You have the luxury of only having to work part time I would say you’re doing ok.

If you try to go for more money he could be spiteful and find ways around getting out of it or even lowering what he already gives you.

nearly £1300 a month is the same as some people’s salary.

Comtesse · 15/08/2025 14:44

I don’t think you’d be at all unreasonable to ask for extra financial support. It’s good he pays the CMS level but it’s obviously a drop in the bucket to his earnings.

FWIW I think it’s appalling that many single parents don’t even get CMS level support but that is irrelevant to your circumstances.

No idea about that one. But, it does suggest she makes a habit of this. Getting pregnant without being in an established relationship.

Who was going to pay for that child if she had been pregnant given that she only wants to work part-time time.

Children aren't a lifestyle choice for benefits and maintenance for someone else to pay for.

veganfortheanimals21 · 15/08/2025 14:59

Of course he should be paying more! You have to look after the child as he will not and therefore he should not only be paying for what the child needs, but he should be paying for the childcare you have been giving his child. You have also missed out on potential career opportunities by being the sole parent. It should also be exactly the same amount he spends providing for his other children. Some of the answers on here are pure nonsense sayng you're greedy. This man made the child and is very rich, he therefore needs to pay a proper proportion of his wages to the child and for the child's mother to look after them in a manner appropriate to what the father earns. And this is from someone who gets a tenner a week for child maintenance as the father has quit his part time job, has three other children by different women and believes children don't need money to live off. No wonder men get everything they want and away with everything when even women set the bar so disgustingly low.

HopscotchBanana · 15/08/2025 10:37

I thought the same

The description that the judge agreed his wife wan not to be near the baby is misleading. The judge can't force OP to let anyone into her house. But that's not the same thing. So it was maybe agreed the wife couldn't attend her home. Dad then said, there's no genuine reason wife can't come, she's going to be as much of this child's life as I am from day 1.

OP simply didn't want her there out of jealousy. It wasn't to protect the child, or any child related reason. As you say, a 6 week old is oblivious. It's all about OP here.

Dad wasn't up for this nonsense. OP tried to backtrack then, realising that the swaying power and control she thought she'd automatically have as "I'm the mother of his child" was actually zero. If she truly thought the wife shouldn't be there, she wouldn't have back tracked at all. That's very telling.

If she goes for more money, whilst choosing not to work when she could, whilst it's already shown her child is more than provided for, already receiving maximum CMS, she's got little chance.

What she will do, even by applying, is piss off a man and his wife who've already shown their tolerance to this situation when OP starts making demands that she feels entitled too. A very fragile relationship with little bond exists between this child and the father, and I also think, going after more money is going to result in a "fuck you" response.

If there were more of a bond then it could be a "fuck you" he'll stay here more of the time and you'll get less maintenance. However, 6yrs of NC, 3yrs of seeing him once every 4mths or so for a few hours in amusement arcades. That's not a child that he wants to integrate at all. So it will most likely be "fuck you" don't contact us again. And they will let him know why when he undoubtedly comes angrily looking for answers as an adult.

God knows what she's going to do in 8yrs when it all stops anyway. If he loses his job next week, next year even, what's her plan then? That should be the the pressing concern. She relies on this to fund herself. Not to cover 50% of a 9yrs olds living expenses. It's funding her part time work status.

You’re just making things up aren’t you? You’ve consistently claimed things that aren’t true and you just keep going. It’s actually quite funny, you remind of someone I used to work with. Could never get anything done because she spent the whole time giving her opinion on things that hadn’t even happened. Great way to while away an hour but not someone to take seriously. Turned out she was addicted to co-codamol. She got fired in the end. Quite sad.

Obviously you can wildly speculate about things but the facts are written down.

The father wasn’t married to the new woman when the baby was six weeks old, and it’s entirely reasonable for a mother to say she doesn’t want a person she doesn’t know fully involved in her six week old baby’s life. Would you have let your six week old DC be looked after by a stranger because ‘they’re oblivious’?

Despite the court agreeing, the father threw his toys out the pram and then the OP capitulated and said let the woman be involved and the hapless father still didn’t stick around. He doesn’t so much seem like he didn’t want the child as he didn’t want to not get his own way.
