Can I Get Back Pay for Child Maintenance?
S.F asks

I was divorced in 2007 after a 5 year marriage (including 2 years separated). We have a 5 year old child and I'm the resident parent.

My ex has been very lax in paying maintenance, for a long time we got nothing and then £9 a week which has now stopped. My main question is would we be entitled to back payments for maintenance not received in the past?

Whether You Can Claim Arrears Depends on Your Situation

If a paying parent has fallen behind on child maintenance, you may be able to recover some or all of what is owed. How far back you can claim will depend on the nature of your existing child maintenance arrangement.

The rules differ depending on whether you have an existing claim through the Child Maintenance Service, a court order, or no formal arrangement at all.

If You Have a Claim Through the Child Maintenance Service

When you have an open case with the Child Maintenance Service, arrears can build up from the date the CMS first contacted the paying parent. Processing a claim and calculating payments can take time, which means the paying parent may end up owing a lump sum covering several weeks or months.

The CMS has powers to collect these arrears. They can deduct money directly from wages, take funds from bank accounts, or use enforcement action through the courts. The CMS does not usually write off what is owed, though older arrears from former Child Support Agency cases may be handled differently.

Arrears owed through the CMS remain payable even if the paying parent becomes bankrupt. Child maintenance debt is treated differently from most other debts and does not get cleared through insolvency.

If you suspect the paying parent is hiding income or understating their earnings, the CMS has a Financial Investigation Unit that can look into this.

If you believe arrears have built up on your case, contact the CMS directly to check the current balance and discuss collection options.

Your situation may be slightly different. ask a question below ↓ and our editorial team will reply with our advice.

If You Have a Court Order

Where child maintenance was ordered by a court, arrears are enforceable through the family courts. You can apply to the court for enforcement action, which may include:

  • An attachment of earnings order
  • A charging order against property
  • Committal proceedings in serious cases

There is no formal statutory limit on how far back a court can enforce unpaid maintenance. However, courts may require solid justification for pursuing older debts, and any limitations in the original court order will apply.

If You Have No Formal Arrangement

Without an existing CMS case or court order, you cannot usually claim back payments for previous years. The CMS can only collect maintenance from the point they open a case and make contact with the paying parent.

Private arrangements are not legally enforceable. If your informal arrangement has broken down, you cannot recover past payments through the CMS or courts. You would need to apply to the CMS or, in certain circumstances, the court to put a formal arrangement in place going forward.

For current rates, how to apply, and what the CMS can do about unpaid maintenance, check the child maintenance section on GOV.UK.

@RICHARD WILDE Sorry to hear about your situation. In the UK, the Child Maintenance Service generally only acts from the date you open a case, so backdating to October 2022 isn't really possible through them. Your best move is to apply through the CMS now and they'll calculate payments based on her income going forward. If your daughter is still in full time non-advanced education (up to age 20), she still qualifies, so don't delay getting a case opened.

Can i claim back dated child maintenance payments from my wife /so to be ex wife as she left the marital home as of 1st October 2022. And she has never helped to support our youngest child who was 16 when my wife walked out. She still does not offer directly or indirectly to support our daughter

Claiming back maintance about a father that declares he is now her father but never admitted before. Never paid a penny but is now supplying my daughter with the money and the means to lean a unsavoury life that Iv sheltered her from
Leanne 25/10/2023 at 7:14 pm
My daughter has recently come
In to connect with her biological father after 14 years. He never been willing to pay or accept she is his daughter. But now he comes in to her life and starts giving her money after money but still won’t accept he’s her father and been missing all her life. How is this far!! He doesn’t know his daughter and doesn’t even understand what he’s given her money towards!!!

How do I get child support arrears when the child maintenance service refuses to go after him. Can I, or my children (now adults), take him to court?
Betty 30/06/2023 at 12:18 pm
Hi
I have a question…
Few years before I stopped child maintenance service because,we had agreement with my son Dad .. so he payed to me regularly every month.
But now again we have a problem with his payment. My question: Can I start again child maintenance services?
SMc 05/06/2023 at 8:09 am
After 4.5 years of paying Child Maintenance, I raised a complaint that in fact I should never have paid any maintenance (except voluntarily) because my 'son' is not my birth child, adopted child or surrogate child. CMS has agreed with this and are now deliberating reimbursement. Are there any precedents for this that I can refer to.

I also wish to claim compensation for the significant financial impact (such as having to declare myself bankrupt as I couldn't manage these payments at the CMS level as well as other debts) and psychological impact (of which there was a great deal for many reasons related to this scenario).

Do I have grounds for both reimbursement and compensation?

Why do you keep saying Ex husband?? My Ex wife has never paid a penny because everyone always sides with the woman. I think you should change the wording in this article as it's totally disrespectful to dads like me who step up and look after their kids when the Ex wife is a complete fraud.

Ok, long story... I have a 16 year old son who has until 6 months ago never had any contact with his biological father, I never claimed maintenance as he was violent and I just wanted to move on with my life, he wasn't in the child's life. 16 years later, my son decided to pursue a relationship w9th his birth father, although i advised against this I support my son is old enough to make his own decionesions.... after 6 months of knowing him and poisoning my son against me, my son got secluded from school and because I grounded him, he chose to go and live with his birth father,, where there are no boundaries in place... that was 3 weeks ago, and last week I received a letter from csa and he had made a claim against me....help!

I didn’t get all the arrears what was due to me when they changed over in 2017 from CSA to child maintenance. I’ve be on to child maintenance and they said it’s right.I didn’t receive a final letter from CSA to say to get in contact about the money changing over.when I saw the amount on a child maintenance letter which I received I thought that not the full arrears. My partner has been ducking and diving between jobs trying to dodge paying his arrears for many years now.it’s 2022 and he’s on benefits I have been told by child maintenance .only paying around £6 something for his child but at weekends he drives coaches I can’t see him doing it for the goodness of his heart which means he must be getting some sort of other money coming in but I’ve even asked them to please check this out the child maintenance service but haven’t really got far.
Is there anyway the CSA can check the old arrears claim from 2017.
I know it’s quite a while ago now but at the time of 2017 went the changed was happening I also had family illness and child bullying issues to attend too.
Stressful time having to deal with it all.

csa will only backdate EXISTING claims nothing else. After 18 years old you can not make a claim unless the child is in higher education (university) and only up till the age of 21.
Mammy 05/11/2022 at 2:30 pm
When I finally split from my ex husband and tried to claim maintance for our 5 sons he used every trick to not pay even though he was working 2 jobs. We never got a penny from him and I'm just wondering how far back could I claim ? The youngest is now 18 and he is laughing saying its to late. He bought a house and set up his own business since we separated .

I’m 19 years old, my real dad walked out on me as a baby? Can I claim child maintenance for the years he hasn’t provided
Cath 30/03/2022 at 9:02 pm
Just a quick question I know all my kids are grown up now but is there anyway I can claim all the maintenance back that CSA got from my ex they wouldn't pay it out due to my ex was paying off alot of arrears I was on benefits at the time and they said I would only be entitled to it when I went back to work so I contacted them once I started my job and they basically said cause he was still paying the arrears Im not entitled to any of it which I think is unfair is there anyway I can claim all my money back

Can anyone give me advice on my situation please. I became pregnant in 1999 my son is now 21, the father is Dutch and left when I was pregnant, I was told back then they couldn’t trace him although I knew the company he worked for and still do know where he works. He never ever paid a thing. Am I able to do anything? Seems a little unfair that his career has rocketed and I’ve struggled to raise our son without any help at all. Thanks I’m advance

My ex husband left the UK about 8 years ago and left me paying for three boys.The CSA said if he left the country the case now would be closed,although 2 of them are now over 18 my youngest now 17, i have heard he is back in the uk can i apply for any back pay as i think its disgusting he left the country to avoid paying any maintenance..
I never touched his pension and he has now left the Navy and does not work but i just wondered if there was a case for getting some money towards their upbringing.
