Key Takeaways
- The most common parenting mistakes in divorce and separation involve putting children in the middle of adult conflict, either as messengers, spies, or pawns.
- Children consistently tell researchers they want contact with both parents and do not want to choose sides, yet many separating parents unintentionally force them to.
- Stopping child maintenance because you are angry with the other parent is both legally risky and unfair to the child, these are two separate issues.
- Courts will enforce child arrangements orders robustly, including with prison sentences, as a recent 2026 contempt case shows.
- Mediation gives parents a structured way to agree how to parent separately, without damaging the child in the process.
PARENTING MISTAKES IN DIVORCE
The most common parenting mistakes in divorce are using children as messengers, criticising the other parent in front of them, arguing openly, linking child maintenance to contact, and trying to control what the other parent does during their time. These behaviours cause lasting harm to children, even when parents mean well. Family mediation helps separated parents agree practical rules that put the child first.
Parenting is difficult at the best of times. It throws daily challenges even when both parents are in a happy relationship and working together. It is far harder when you cannot bear to be in the same room as the other parent, let alone communicate with them or make important parenting decisions together. Over the past decade we have worked with thousands of separating families, and we see the same mistakes made again and again. Some are obvious, some feel harmless in the moment, and all of them are avoidable.
What children want after their parents separate is consistent across the research. According to Cafcass guidance on supporting children through separation, children want to feel safe, loved, and able to maintain a relationship with both parents. NSPCC research on separation and divorce confirms that children do best when they keep contact with both parents, unless there is a genuine safeguarding reason not to.
The 10 mistakes below all push in the opposite direction.
Before you read on, a reassurance. Some of our own mediation team have made these mistakes during their own separations, and so have many of our clients. This is not about blame. It is about recognising the pattern and choosing to do something different. If you are planning how to split time with the children, our full guide to child arrangements is a useful companion piece.
The 10 Parenting Mistakes to Avoid in Divorce or Separation
Asking the children to pass on messages to the other parent
“Can you tell your dad you have an extra ballet class Thursday.” “Can you ask your mum for £50 for the school trip.” “Tell your dad his solicitor needs to respond by next week or it’s going to court.”
All three are real messages one parent has asked a child to pass on to the other. Even the innocuous ones are a mistake. They put adult responsibility on a child and show them their parents cannot talk to each other. What starts as ballet class reminders often escalates into messages about solicitors and court.
Do this instead: Use a dedicated co-parenting app or a simple shared notebook that travels between homes. Keep adult business out of the child’s earshot entirely.
Interviewing your child when they return from the other parent
“Did you have a nice time? What did you eat? What is daddy’s new girlfriend like? Did she stay overnight?”
Children consistently say one of the things they hate most after their parents separate is being interrogated about the time they spent with the other parent. They feel they may be betraying a trust. They feel pressure to give the answer the questioning parent wants to hear. They particularly hate being asked about a new partner.
Do this instead: Ask open, warm questions like “did you have a good weekend?” and leave space for the child to share on their terms.
Saying derogatory things about the other parent in front of them
This one is hard. If your ex has behaved badly, left the family, or taken up with someone new while you struggle to afford school uniform, biting your tongue feels unfair. But when you criticise their mum or dad in front of them, you are also criticising half of the child. Children internalise negative comments about a parent as negative comments about themselves.
Do this instead: Be honest about what is happening in age-appropriate terms, but always respectful. Save the venting for a friend, a therapist, or a divorce coach, never for the child.
Arguing in front of the children or physically fighting
Adults who grew up with constantly arguing parents describe it as one of the most lasting memories of their childhood. Research by the Early Intervention Foundation for the DWP shows that frequent, intense, poorly resolved parental conflict has a measurable impact on a child’s mental health, schoolwork, and adult relationships. The two people they love most visibly hating each other is frightening.
Do this instead: Agree never to argue in front of the children. Take disputes to family mediation where there is structure and a neutral third person. Ask yourself: “Is what we are arguing about more important than the harm we are causing our child by arguing?”
Stopping child maintenance because you are angry or unhappy with the arrangements
Some non-resident parents stop paying when they feel aggrieved. It is always a mistake. In law, both parents are responsible for the financial costs of raising their child. Child maintenance is not conditional on contact and a judge will take a dim view of stopping it as a bargaining chip.
The flip side is equally damaging. Do not stop the other parent seeing the child because they have fallen behind on maintenance. Children are not a pay-per-view service. Contact and money are two separate matters and must be handled separately.
Do this instead: Keep paying (or keep allowing contact) while you address the other issue through proper channels, the Child Maintenance Service for money, and mediation or court for arrangements.
“We see so many parents who mean well but fall into these traps because nobody has told them there is a better way. Most of the time, once a couple sits down in mediation and hears how their behaviour is landing on their children, they change course. Parents are not the enemy here, they are almost always doing the best they can with what they know. Mediation gives them new tools.”

Struggling to agree child arrangements with your ex?
Family mediation gives you a structured, confidential space to agree practical parenting arrangements. Start with a free 15-minute call to see if it’s right for you.
Trying to control how the other parent parents when the child is with them
You have spent months getting a bedtime routine nailed, only to have it fall apart at the other house. Junk food, later bedtimes, different rules. Unless there is a genuine safeguarding risk (the kind where you would phone 999), there is very little you can do about how the other parent parents. Trying to micromanage the other home just drives you mad and puts the child in the middle.
Do this instead: Aim for broad consistency on the big stuff (bedtimes on school nights, no alcohol or unsupervised internet access) through a written parenting plan, and let the small stuff go.

A written parenting plan makes it much easier to agree routines, handovers, holidays, and how you handle disagreements. Our sister site The Divorce Circle has a free, step-by-step parenting plan generator that takes around 10 minutes and produces a document both parents can refer to.
Dropping the child off at the end of the road to avoid seeing the other parent
Some parents do this thinking it spares the child from witnessing tension. In fact it signals the opposite: that the adults in their life cannot even tolerate being near each other. There are genuine exceptions where handovers at a neutral location or via a third party are necessary, particularly where there has been domestic abuse. For most families, though, a brief civil handover at the doorstep is far healthier for the child.
Do this instead: Keep handovers short, neutral, and predictable. A 30-second doorstep “hi, she’s had a good week, see you Sunday” costs you nothing and means the world to your child.
Reporting the other parent to the police or social services without establishing the facts
Always report genuine safety concerns about your child. What is not acceptable is weaponising the police, children’s services, or false allegations to damage the other parent’s case or punish them. Fabricated or exaggerated reports can result in your child being placed on a child protection plan, and courts treat them seriously when deciding child arrangements.
Do this instead: If you have real safeguarding concerns, report them properly and keep contemporaneous notes. If you are frustrated by the other parent’s behaviour but the child is not at risk, take it to mediation or, if necessary, apply to court.
Refusing to let the child have a relationship with their new family
“I don’t mind them seeing my ex, but not if the new partner is there.” It is an understandable feeling, particularly if a new partner was involved in the breakdown of the relationship. But the reality is that more loving, supportive adults in a child’s life is good for the child.
Do this instead: Agree in mediation when and how new partners will be introduced, what role they will play in day-to-day parenting, and how you will handle big events like birthdays and school pickups.
Not letting toys, clothes, or gifts travel between homes
We have seen cases where a child has had to change clothes in a car at handover because neither parent would let “their” clothes go to the other house. Well-meaning grandparents give gifts and then insist they stay at their house only. Imagine being told your favourite jumper could not leave your friend’s house when you went to visit.
Do this instead: Toys, clothes, and gifts belong to the child. Let a favourite teddy, blanket, or game travel between homes. The continuity helps them settle and signals that both houses are theirs.
What Happens If You Break a Child Arrangements Order?
When separated parents cannot agree, the court can make a Child Arrangements Order setting out where the child lives and when they spend time with each parent. Once made, the order is legally binding, and the consequences of breaking it can be serious.
The Family Court has a range of enforcement powers under the Children Act 1989, including unpaid work, fines, compensation orders, transferring residence to the other parent, and committal to prison for contempt of court. Courts use imprisonment as a last resort, but they will use it when parents repeatedly and deliberately defy orders.
Recent Case: A 2026 Contempt Ruling
In a Family Court judgment handed down in 2026, a father was sentenced to three months’ immediate imprisonment for contempt of court after repeatedly defying a Specific Issue Order requiring him to return his 16-year-old child to the mother’s care.
What happened: The court made the order on 2 January 2026. The father refused to comply despite proper service. On 20 January 2026 the court issued a Search and Return Order, and police physically returned the child from South Wales to the North East, arriving late at night. The child, who has learning difficulties, experienced police intervention, cross-country travel, and a distressing late-night return home. The father failed to attend multiple hearings, including his own sentencing.
What the court said: The judge found deliberate and sustained breach of a court order, clear attempts to evade service, and a history of previous contempt findings including prior prison sentences. The harm to the child was assessed as “medium”, with emphasis on how avoidable it had been. The sentence was not suspended because of the repeated breaches, lack of remorse, and ongoing non-engagement.
Why it matters: This case shows that courts will enforce child arrangements orders robustly where a parent refuses to engage. Police powers can and will be used. The clear message is that ignoring a court order ultimately harms both the child and the parent defying it. Mediation avoids this outcome by producing arrangements that both parents have agreed to and are therefore far more likely to follow.
How Family Mediation Helps You Avoid These Mistakes
Most of the 10 mistakes above come from one root cause: two parents who cannot talk to each other trying to parent a child who loves them both. Mediation fixes that by giving you a neutral, structured way to have the conversations that keep getting away from you. A trained family mediator helps you agree on:
- Where the child lives and when: term time, school holidays, special occasions.
- How you communicate: app, email, notebook, direct conversation, and for what.
- Rules and routines: bedtime on school nights, screen time, discipline, diet.
- Introducing new partners: timing, language, role.
- Handling disagreements: who you call first, how you de-escalate, when to come back to mediation.
If you are at the stage where one of you is considering applying to court, the law in England and Wales requires you to attend a MIAM (Mediation Information and Assessment Meeting) first, unless you are exempt. If you then need to apply to court to sort out arrangements, our guide to completing a C100 form walks you through the process.
Summary
The most common parenting mistakes in divorce are not born of bad intent. They are made by people who are hurt, exhausted, and trying to do the best they can in a situation they never wanted. But children notice. They hear the messages passed through them, feel the interrogations about the other home, internalise the criticism, and carry the anxiety of witnessed conflict for years.
The best way to avoid these mistakes is to agree practical rules together, ideally in mediation, and write them down. A parenting plan gives you a script for the hard moments and a reference for when you disagree. And as the recent 2026 contempt case shows, the courts are willing to use their full powers, including imprisonment, against parents who refuse to engage with the legal process. Mediation is almost always the better option.
Frequently Asked Questions
What are the most damaging parenting mistakes after separation?
The most damaging are those that involve the child directly in adult conflict: using them as a messenger, interrogating them about the other parent, criticising the other parent in front of them, and arguing openly in their presence. Research consistently shows these cause lasting harm, affecting children’s mental health, schoolwork, and adult relationships.
Can I stop child maintenance if my ex is not letting me see the children?
No. Child maintenance is a legal obligation of both parents and is not linked to contact. Stopping payments will harm your child, weaken your legal position, and is frowned upon by courts. Deal with the contact issue separately through mediation or a court application.
What can the court do if my ex breaches a Child Arrangements Order?
The Family Court has a range of enforcement powers including unpaid work, fines, compensation orders, transfer of residence, and in serious cases committal to prison for contempt of court. A 2026 Family Court case saw a father imprisoned for three months for repeatedly refusing to return his 16-year-old child as the court had ordered.
Should I stop my child seeing my ex’s new partner?
Generally no, unless there is a genuine safeguarding concern. Research shows children benefit from having more loving adults in their lives. If you have concerns about how and when a new partner is introduced, or the role they are taking, mediation is the right place to agree boundaries.
How can I communicate with my ex without involving the children?
Use a dedicated co-parenting app (such as OurFamilyWizard, TalkingParents, or 2houses) or a shared notebook that travels between homes. Keep adult issues to a short, civil written channel and keep the child out of it entirely.
What do children actually want after their parents separate?
According to Cafcass and longstanding research, children want to feel safe and loved, to maintain a relationship with both parents unless there is a genuine risk of harm, to be heard without being asked to make decisions, and to be told in honest, age-appropriate terms what is happening. They do not want to choose between parents, and they do not want to be responsible for adult feelings.
When should I involve the police or social services?
Always report a genuine concern about your child’s safety. Use 999 for immediate danger, or your local authority children’s services for welfare concerns. What is not appropriate is reporting the other parent as a tactic in a contact dispute, which can cause serious and lasting harm to the child and damage your own case.
Can family mediation help if we have already argued in front of the children?
Yes. Most parents who come to mediation have already made some of the mistakes on this list. The point of mediation is not to judge but to reset the approach. A mediator can help you agree practical rules for how you communicate, hand over, and handle disagreements going forward, so the pattern does not continue.
