Co-parenting after divorce: how to make it work long term

In the early days after separating, co-parenting is often about getting through the week: handovers, school runs, who has the PE kit. Over time, the question changes. How do you keep this working for ten or fifteen years, through new schools, new partners, house moves and teenage years?

No one gets it right all the time. But a few habits make a real difference, both to your children and to your own peace of mind.

Why the way you get on matters

The research here is fairly consistent. A major evidence review for the government by the Early Intervention Foundation found that frequent, intense and poorly resolved conflict between parents puts children's mental health and long-term life chances at risk, whether the parents are together or apart (Early Intervention Foundation, for DWP).

Young people say the same thing in their own words. In a survey for Resolution, 88% of young people with separated parents said it's important children don't feel they have to choose between their parents (Resolution / ComRes, reported by Family Law).

That's not meant to add guilt. Disagreeing is normal. What matters is keeping conflict away from the children, and resolving it rather than letting it run on for years.

Children don't need parents who agree on everything. They need parents who don't make them pick a side.

Co-parenting or parallel parenting?

Co-parenting means working together closely: shared rules across both homes, joint decisions, perhaps attending school events together. It works well when you can communicate calmly.

Parallel parenting means each of you parents independently in your own home, with communication kept to the essentials. It suits higher-conflict situations, and it can be a better choice for children than forced cooperation that keeps tipping into arguments.

Many families move between the two over time. You might start parallel and soften as emotions settle, or the other way round. Either is legitimate.

Communicating with your co-parent

Treat it like a working relationship. Polite, clear and focused on the children. You don't have to be friends.
Pick one main channel, such as email, a shared calendar or a co-parenting app, so information doesn't get lost across texts, calls and conversations at the door.
Share the important things promptly: school reports, medical appointments, worries about friendships. Both parents with parental responsibility have a right to be involved in big decisions.
Keep handovers short and calm. Handovers are where children see you together most, so they're worth getting right.
Never use the children as messengers, and avoid asking them questions about the other household.
Assume good intentions where you reasonably can. A late reply is usually just a late reply.

Changing arrangements as children grow

An arrangement that works for a four-year-old rarely works for a fourteen-year-old. Build in regular reviews, perhaps once a year or at natural points like starting secondary school.

Younger children often do better with shorter, more frequent time with each parent and very consistent routines.
Primary-age children may manage longer stays and benefit from a visual calendar so they know what's happening.
Teenagers have friends, jobs, clubs and opinions. They may want more flexibility, or to spend more time in one home. Listen to them, and try not to take it personally.

Cafcass's free Our Child's Plan tool can help you update your parenting plan together. If you have a court order, you can agree to do things differently, but if you can't agree, the order still applies until it's changed.

Moving a long way away, or abroad, can have a big effect on the other parent's relationship with the children. Talk about it early. Taking a child out of the UK usually needs the consent of everyone with parental responsibility, or the court's permission.

New partners and new families

New relationships are one of the most common flashpoints. A few things help:

Take introductions slowly. Wait until the relationship is settled before introducing a new partner to the children.
Tell your co-parent first, before the children meet them. Hearing it from a child is much harder.
Keep roles clear. A new partner can be a caring adult in your children's lives, but they're not a replacement parent, and discipline is best left to you, at least at first.
Make room for feelings, including your children's mixed loyalties and your own feelings about your ex moving on.

Money and child maintenance

Disagreements about money often spill into co-parenting. Having a clear arrangement for child maintenance helps keep the two separate. You can agree it between you or use the Child Maintenance Service. It's free to apply, and payments arranged through Direct Pay are free. If the service collects payments for you, the paying parent is charged 20% on top and the receiving parent has 4% taken off (GOV.UK).

Child maintenance and time with the children are separate. One shouldn't be used as leverage for the other. It also helps to agree upfront how you'll share extras such as school trips, clubs and phones.

When it breaks down

If you've hit a wall, there are steps short of court:

Family mediation. A mediator can help you reset arrangements. The government's voucher scheme gives up to £500 towards mediation for cases involving children (GOV.UK).
Counselling or a parenting course, together or separately. Relate offers support for separated families (Relate).
Court. If an existing order isn't being followed, you can apply to enforce it. If circumstances have changed, you can apply to vary it. The court fee for most Children Act applications is £270 (GOV.UK).

If co-parenting has become frightening or controlling, it's not a communication problem to solve with better messages. Abuse can continue after separation, often through arrangements for children. If you're in danger, call 999. The National Domestic Abuse Helpline (0808 2000 247) is free and open 24 hours (GOV.UK), and Samaritans are there any time on 116 123.

Common questions

What is the difference between co-parenting and parallel parenting?

Co-parenting means working closely together with shared rules and joint decisions. Parallel parenting means each parent runs their own household independently, keeping communication to essentials. Parallel parenting often suits higher-conflict situations.

How do I introduce a new partner to my children?

Wait until the relationship is settled, tell your co-parent before the children meet them, and take it slowly. Keep parenting decisions and discipline with the parents, at least at first.

Can we change a child arrangements order if we both agree?

You can agree to do things differently, but the court order still applies if you later disagree. To change it formally, you can apply for a consent order or to vary the existing order.

What can I do if my ex isn't following the child arrangements order?

Try to resolve it through communication or mediation first. If that doesn't work, you can apply to the court to enforce the order. The court fee for most Children Act applications is £270.
