If you're currently going through the Child Maintenance Service (CMS) and wondering whether you can leave and set up a private arrangement instead, the short answer is yes. Many parents choose to do this, and the CMS allows parents to close their case and make their own arrangements.
What is a private arrangement?
A family-based arrangement is a private agreement where both parents decide on child maintenance terms without involvement from the CMS or any other government body.
This can work well when both parents are able to communicate reasonably and trust each other to stick to what has been agreed. It also avoids the fees that the CMS charges to both parties when they collect and manage payments.
Private arrangements are flexible, accommodating various contributions like cash, school uniforms, clubs, or holiday costs. As long as both parents are satisfied with the arrangement, it can take whatever form suits your circumstances. Keeping records such as bank statements, receipts, or written confirmations of what has been agreed can help if questions arise later.

When the Child Support Agency (CSA) was still running, parents with care who received certain benefits faced significant pressure to use the statutory system. That is no longer the case. The CMS replaced the CSA, and the rules were updated to give parents more choice.
If you or the other parent receives benefits, you can still opt for a private arrangement. However, the practicality of this depends on how maintenance payments interact with your specific benefits. The parent with care is allowed to keep a portion of any maintenance received before it affects their benefit payments. For current figures on how maintenance interacts with benefits, check the GOV.UK website, as thresholds can change.
This change made private arrangements more accessible to more parents, though individual benefit circumstances may vary. Parents with international maintenance cases should also be aware that the CMS has specific arrangements for these situations, which may affect your options.
Your situation may be slightly different. ask a question below ↓ and our editorial team will reply with our advice.
What to think about before leaving the CMS
Before closing your CMS case, consider these factors.
- Do both parents genuinely agree to the arrangement? A private setup only works if both sides are willing to honour it.
- Is the amount fair? You can use a child maintenance calculator to get a sense of what the CMS would have worked out. This gives you a reasonable starting point for discussions.
- What happens if payments stop? With the CMS, there are enforcement options if a paying parent fails to keep up. With a private arrangement, you would need to return to the CMS or take other steps if things break down. Be aware that there may be a fee to reapply for CMS services.
- How might this affect the children? If arrangements fail, children may be left without adequate support while a new case is established.
There is no legal requirement to have a formal written agreement before leaving the CMS. However, writing down what you have both agreed to can help avoid misunderstandings later. Some parents keep things informal, while others feel more comfortable with something documented, whether that is an email exchange, a letter, or a more detailed written agreement.
If there is any disagreement or complexity, mediation or legal advice can help establish terms that work for both parties.
Notifying the CMS
If you decide to move to a private arrangement, you will need to notify the CMS. This is straightforward and can usually be done by phone or through your online account.
Until your case is officially closed, the CMS will continue to treat it as active. This means they may still attempt to collect payments from the non-resident parent, which can cause confusion if you have already started paying or receiving money privately.
Once the case is closed, the CMS will no longer be involved. If at any point the private arrangement stops working, either parent can ask the CMS to open a new case.
For many families, a private arrangement offers a simpler and more flexible way to handle child maintenance. It removes the fees, allows for tailored agreements, and can reduce conflict when both parents are willing to cooperate. Whether it is right for you will depend on your own situation and the relationship you have with the other parent.

Told she wouldn’t be eligible to apply again, please can someone help? As this ain’t nice what she is doing, what has she been doing for the last 10 years providing? Why want me to pay all of a sudden when I’m not even around! I was never married, just got trapped!
My partners ex wife had a contact to pay on from csa put on him over a year ago. They are taking so much money from us to use this system but his ex wont have it removed and come to a mutual arrangement because she knows there taking so much and she is enjoying that fact.
Is there anything he can do to have to contact to pay removed? Surely he deserves the chance to prove himself that he can pay without it
Where do I stand regarding the following
I’m involved in an open case, have been for several years, I’ve had no contact with the mother apart from the odd text message or phone call and have never seen my daughter, she is now 22
Several months ago our case worker contacted me and made me an offer on behalf of the mother to pay £10k and the case would be closed, I refrained this offer as I did not have sufficient funds available then, 2 weeks ago I did, so I contacted the mother, asked if the offer was still available, she said yes, but wanted £11k now, which she would pay any arrears etc and close the case, she sent her bank details and I paid, she’s now claiming to not wanting to close the case, I have been in contact with the CSM and they have not been very helpful however they have tried contacting the mother but she is ignoring all calls
I’m not sure where I stand with this matter
After a day from Hell yesterday, my boyfriend and his ex wife finally reached an arrangement they are both happy with.
My only concern is that once she’s started the csa procedure, can it be stopped?
We had a private agreement to pay maintenance which we reviewed after a couple of years and I was paying £500 per month into ex's mums bank account. Now we reviewed and we used the payment calculator so my payments have gone up - not a problem so far at all ..
But now she is demanding that I pay over 36k in arrears as she has used some form of calculation when not knowing my salary at all ..
This is really putting a strain on me as I do not know how this figure was got and as we had a family agreement in place where is this figure come from ?
Do i have to pay arrears if we agreed on a monthly sum ?
I am at my wits end and feel very stressed ..
Anyone help me ??
Why do they go after Dads that work for the forces, NHS, police, low earners etc?
Why do they illegally use the wrong tax year?
No wonder Dads that don’t pay will do anything to not pay a FAIR amount!
The CMS is worse than the CSA it is a private money making business under the guise of the government
Why haven’t the CSA and CMS been taking to the high court for murdering parents that pay.
Taking driving license, passport, imprisonment that’s against human rights, draconian law.
It is perfectly set up for the bitter angry ex. It is not a system set up for the child’s interests.
My ex opened a case with the cms saying I’m earning a certain amount and they have used this figure from 2017 tax year. I have now changed jobs which means I earn less but they still use my tax year from 2017. We are now in July 2019.
I am giving more than they advise and also paying for food etc towards my ex and my child all of this I can prove as it’s direct pay.
My ex then agreed to cancel the cms via the online portal to come to a family based/private arrangement.
I have tried calling the cms and they have put the phone down on me three times,
Now several months down the line a letter from the cms turns up still saying they are using the tax year 2017! Clearly stating that if I don’t pay every week/month that it’ll switch to collect and pay.
My question is, what do I do?.....
Is there anything. Anything I can do to stop making payments. I need control of most of what money I pay so I can help our children.
Nails hair holidays (without the kids) (her partners car MOT)
I'm not thick I know that's my money.
I believe my kids get fed but it doesn't cost over £100 each month to feed them and her.
secondly have the laws changed where by if a parent is with holding contact to a child then CSA payments are non- eligible ? I have been told this but am unsure of the truth in it.

My partner has a 13 year old daughter. He had always made regular maintenance payments to his ex partner via direct debit until April 2016. In March 2016 he received a letter from CSA to say that his arrangement for maintenance payments was coming to an end and he needed to make contact to make new arrangements. He did this and was in communication with CMS once it changed over requesting certain details. Since the last correspondence in August 2016 he hasn't heard anything further and no further payments have been taken. We can only assume this is because his ex partner no longer wants to pursue a claim as she no longer wanted him to have contact with his daughter and has decided she no longer wants his money either. Is this even an option as I am concerned that this could result in debt and arrears. Can the receiving parent simply opt out? Please advise as I can't find any information out there in relation to this. Thanks
My partner and I separated 9 years ago and I’m the main career of our two daughters. We originally had a legal agreement that he left the majority of equity in house and I wouldn’t chase maintenance payments. He has made the decision he no longer wants to see his daughters eldest being 17 now. Can she make a personal claim against him ?
I have separated fro the mother 9 years ago.
The 17 year old finished education over a year ago and does not work. I understand i should not be paying maintenance for her, yet Child beneift won't speak to me as i am not the claimant, and CSA will continue to take from my wages, as long as CB is being paid to the mother. Can anyone help here?
Obviously its not in the mothers interest to tell CB to stop paying her for the 17 year old.
What happens in april when CSA no longer exists?
Cheers all!
I’ve been paying a financial agreement with my x partner for 7/8 years now and due to my job was a large amount of money though due to changes in work and not working now at all where do I stand now with payments as ive always said if and when I started work again on same pay it would go back to that agreement.
However out of the blue the ex has now started a new case with effect from 27th of this month, because she says she wants to "keep an eye on his earnings, and make sure she gets what shes entitled too"..
Therefore all payments need to be paid to the csa every friday, but.... the ex still expects my husband to pay the 280 direct into her account on the 1st april. This would mean my husband would be paying nearly £600 in child maintenance for april!!!
There is no way we can afford this.
My husband understands that hes legally obliged to pay the csa the new weekly anount, but is refusing to pay the 280 directly into her bank account additional to that.
Csa are sitting on the fence and not giving a definitive answer on whether he needs to pay her, all they keep saying is the case opened 26th march and he has to pay them every week.
As long as my husband pays the csa weekly is there any legal repercussions if he does not pay her the amicable agreement amount on the 1st???
We left the CSA a couple of years ago.m and have a signed private agreement following mediation. I have always always paid everything. Recently she threatened to refuse for me to go on a holiday with my daughter that I had thought was agreed and had paid for. I said I would take her to court or withohold maintenance, this prompted a change of heat and it was then all resolved.
Anyway she has gone to the Child Maintenance now and made an application and they say I have to pay by them even though I have an agreement as it is not from a court and is over a year old. Can I be forced back through the CSA? Also what deduction am I entitled to as they didn't seem to know. Mileage and food? Thanks for any help.

We have a baby ourselves, and my partner is self employed so this is causing us a lot of stress. Please help!
Thank you
What can I do
I understand the Law has been changed since 1998; however, if the original court agreement was set, then are they actually allowed to change any arrangements?
Furthermore, rather than check via government departments to see if the child/adult has paid National Insurance, they actually rely on the mother to tell the truth when asked about any circumstantial changes that have occurred to finish the CSA payment at this point.
Where does this leave honest and hard working individuals who would like to finish arrangement? I mean is it worth going to a solicitor?
I agreed to receive child maintenance mutually in 2013. Since then we've been through a lot of hardship being redundant and homelessness and ex didn't come forward to help with kids even knowing his kids suffering due to homeless situation, is it possible to go to CSA to make him realise the amount he pays for 2 kids just unfair as he doesn't even visit them regularly let alone keeping them overnight.
I don't have funds to go to court and fight for it.
Any suggestions and advice would be appreciated.
A month ago my daughter decided she didn't want to go back to her mum's house and has been living full time with me. Is there anything I can do to stop CSA payments even briefly? I could do with the extra money for my increased food bills.
Now she has put a application fo child maintenance and they have written to me saying they have calculated £4312 per year as I have no visitation/overnight.I was having my daughter two nights a week but she stopped that so she could claim the highest amount, if I still had my daughter 2nights that figure would of come down to 3170. This legislation just encourages the one parent to denies access so she can get more, it's absolutely disgusting!!!
She regularly stops his weekly access on a whim ...children are 'tired' or they are away or innumerable other things.
I can't bear to see it as he's a loving caring daddy and his kids clearly adore him
He has equal rights but doesn't want to cause waves
Any suggestions?
You are responsible as a parent for the safety and welfare of your child, don't point the finger or put that responsibility onto others.
This new system weeds out those women who kicks the father out of their child's life and moves on whilst putting him in the gutter.
It also weeds out those men who think having children is going to be good only for receiving benefits!
You had children, That's a life long commitment. Resolve all issues with your partner. If you have no idea where your partner has gone, then why? If he or she is supposed to be the parent to your child, why?
Irresponsible selfishness is the problem at play here. And the government, taxpayer, and benefits system constantly gets accused of doing wrong and getting the blame for decisions that parents solely made!
E seeing my kids
I am at my witts end with the CSA and really need advice.
My ex husband has told the CSA that his wifes children currently live full time with them so he receives a large reduction, the CSA have also said that I have to pay back thqat reduction amount from the date that he remarried ( £1800)
However he has lied, the children do not live with him and his wife they reside with their father some 140 miles away, I have provided proof from the courts and cafcass ( from my residence order) that they dont live with my ex, ( in the form of his own court statements)
However the CSA say that because the wife is claiming child benefit the reduction and debt will stand? I have spoken to the child benefit people who where shocked by this ruling as there rules state very clearly that child benefit can be paid to a no residential parent.
So where do I go from here? I have been through the complaint procedure and have been advised to speak to my MP??????
The CSA said that I cant cancel them dealing with my case however everywhere I have read I can?
ANY HELP PLEASEEEEEEEEEEEEEE LOL
