Key Takeaways
- UK law dropped the word “custody” years ago. Courts in England and Wales now make a child arrangements order under the Children Act 1989, and every decision turns on one thing: the child’s welfare.
- Shared care is common, but not automatic. A parent is usually only refused time with their child where there is a real concern for the child’s safety or wellbeing.
- The most common reasons are domestic abuse or a risk of harm, drug or alcohol misuse, serious conflict or parental alienation, an unstable home, and being unable to meet the child’s day-to-day needs.
- A proposed law change, the Courts and Tribunals Bill, would remove the automatic presumption that involving both parents is best. It is not yet law, but it points to closer scrutiny where abuse is alleged.
Few things frighten a separating parent more than the thought of being pushed to the edges of their own child’s life. If your relationship has broken down and you are scared you might not get to share the care of your children, that worry is completely understandable. It is one of the most common fears we hear.
Here is the reassuring part. UK courts start from the view that children usually do best when both parents stay involved, so shared arrangements are the norm rather than the exception. A parent is not refused time with their child because of a messy break-up, because they earn less than the other, or because they were not the one doing the school run. It takes something more serious than that.
That said, there are situations where a court will limit or refuse shared care, and it is almost always down to a genuine concern for the child. Below are the main reasons that happens, what the court is really weighing up, and a change in the law that could shift how these decisions get made. If you want to talk through your own situation, Osbourne Pinner offers a free 30-minute consultation with a family law solicitor.
First, a quick word on “custody”
Most people still say “custody”, but that word vanished from UK law a long time ago. Courts in England and Wales now make a child arrangements order, which simply sets out who a child lives with and who they spend time with. Both parents usually keep parental responsibility, meaning a say in the big decisions like schooling and medical care, even when the child lives mainly with one of them.
So when people talk about “joint custody”, what they normally mean is a child arrangements order that splits the child’s time between two homes. One thing worth knowing: “joint” does not have to mean “equal”. A 50/50 split is possible, but the court is under no obligation to divide the time down the middle. We look at whether a mother can refuse a 50/50 split in a separate guide.
The one thing that decides everything
Every decision about a child comes back to a single test: what is in the child’s best interests. This is the welfare principle in the Children Act 1989, and it outranks whatever either parent happens to want.
To weigh it up, judges work through a welfare checklist. It covers things like the child’s own wishes and feelings, their physical and emotional needs, the likely effect of any change, and any risk of harm. Every reason below only matters because of how it feeds into that checklist.
The 7 reasons a parent might not get joint custody
None of these is an automatic bar. They are the factors that, if they are serious enough, can lead a court to limit or refuse shared care.
1. Domestic abuse or a risk of harm to the child
This is the big one. Where there is evidence of domestic abuse, violence, or any risk of physical or emotional harm, the child’s safety comes first, full stop. That can mean supervised contact, indirect contact such as letters or video calls, or in the most serious cases no direct contact at all. The abuse does not have to be aimed at the child either. Harm to the other parent counts too.
2. Drug or alcohol misuse
It is not the addiction itself that decides things, but the effect it has on the child. If a parent’s drinking or drug use makes their care unreliable or unsafe, a court may limit their time until they can show that has changed. Evidence of treatment and a genuine period of stability can make a real difference here.
3. A pattern of conflict or parental alienation
Shared care only works if two parents can communicate about their child. Constant conflict that pulls the child into the middle is damaging, and courts notice. So does parental alienation, where one parent tries to turn the child against the other. There is a bitter irony to it: a parent who plays that game can end up with less time, not more, because the court treats it as harmful to the child.
4. An unstable or unsafe living situation
Children need routine and a safe place to sleep. A home does not have to be big or smart, but it does need to be stable and secure. A parent with no settled accommodation, or a home the court considers unsafe, may struggle to be granted overnight or shared care until things are on a firmer footing.
5. Being unable to meet the child’s everyday needs
This is the practical side of parenting: getting a child to school, to appointments, fed, and looked after day in, day out. If a parent has repeatedly not shown up for that, whether through work patterns, ill health, or simply not engaging, a court may question whether shared care is realistic for them right now.
6. A big move or relocation
If one parent wants to move a long way off, especially abroad, an even split becomes hard to run. School, travel and stability all pull against it. In those cases a court often leans towards the child living mainly with the parent who can offer continuity, with generous time built in for the other.
7. The child’s own wishes
The older and more mature the child, the more weight their views carry. A court will never simply hand the decision over to a child, but a settled, well-reasoned preference from an older teenager is taken seriously. If a child is firmly against spending equal time with one parent, and there are sound reasons behind it, that can shape the outcome.
A change on the horizon: the Courts and Tribunals Bill
One thing is worth flagging, because it could change how these decisions are made. At the moment the law includes a presumption that involving both parents in a child’s life furthers their welfare. The Courts and Tribunals Bill, introduced to Parliament in February 2026, proposes to remove that presumption from the Children Act 1989.
The idea is to stop the presumption getting in the way where there are allegations of domestic abuse, so courts start each case with an open mind rather than an assumption. It is not law yet, and it was still working its way through Parliament in mid-2026, so the current rules still apply for now. But it is a clear sign that courts are being pushed to look harder at safety before ordering shared care.
Refusal is rarely all or nothing
It helps to know that a court refusing “joint custody” almost never means a parent is cut off completely. There is a whole range in between: overnight stays, daytime visits, supervised contact at a contact centre, or indirect contact by phone, video or letter. The court wants to keep a safe relationship going wherever it can, not to punish a parent.
Worried you might be refused shared care?
If you are anxious about this, the worst thing you can do is nothing. Get advice early, keep everything focused on the children, and resist the temptation to use them as a bargaining chip, because that always backfires. Most parents have to attend a Mediation Information and Assessment Meeting, or MIAM, before they can apply to court. If you cannot reach agreement, you apply for a child arrangements order using Form C100, which now carries a court fee of £270 after the July 2026 increase. Our child arrangement order solicitors can talk you through where you stand before you take that step.
The key thing to hold onto is that these decisions are not about labelling one parent good and the other bad. They are about what keeps your child safe and settled. Show the court you can offer that, and you put yourself on solid ground, whatever the history between you and your ex.
