It is eleven at night and your phone lights up again. WhatsApp, a text, an email, all from your co-parent. If that is your evening most evenings, you have probably wondered whether you are allowed to just block them.
In most cases, yes. In Ireland and the UK you can mute or block your co-parent on WhatsApp, text and email, as long as one agreed way to communicate about the children stays open and nothing in a court order or written agreement says otherwise. The aim is not to cut them off. It is to stop being reachable everywhere, at every hour, and to move everything about the children into one calm place.
The short answer
No law in Ireland, England and Wales, Scotland or Northern Ireland requires you to be reachable on every channel your co-parent prefers. What matters, to the other parent and to a court if it ever gets that far, is that arrangements for the children work and that you are not getting in the way of them.
That is the line to hold onto. Choosing one channel for everything about the children is reasonable. Blocking every route so that the other parent cannot reach you about the children at all is a different thing, and it can work against you.
Two exceptions are worth checking before you change anything. If a court order or a written parenting plan says how the two of you communicate, follow it. And if it names a phone number for emergencies, keep that one open. If you are unsure what your order says, a solicitor or a free legal advice service can tell you, and our find help pages list them by country.
Why so many co-parents end up here
When every channel is a way in, there is no off switch. A quick question about a school form turns into a row by text. A voice note arrives that you have to listen to twice and cannot search later. An email lands on a Sunday night and sits in your head until Monday. A message is deleted for everyone before you have read it, and you are left wondering what it said.
Some of it is simply habit. Two people who used to share a home are used to messaging each other about everything, and that does not stop just because the relationship has. Some of it is something else. Constant contact can be a way of keeping control, of making sure the other person never quite gets to switch off.
You do not need to decide which it is to decide that it has to change. Either way, being available on four channels at all hours is exhausting, and it rarely makes arrangements for the children any better.
When one parent leaves the app
There is a pattern worth knowing about. When one parent stops using a shared co-parenting app, the conversation often drifts back to WhatsApp, text and email. Those are the places with no tone check and no single record, and they are where things tend to become difficult again.
You do not have to follow. If the agreed channel is the app, keep your side of the conversation there. If they will not use it, you can still choose one channel, such as email, and keep to it. One channel is the boundary. Which one matters less than keeping to it.
How to move to one channel, step by step
- Choose the channel. A co-parenting app is built for this, with the calendar, messages and costs in one place. If that is a step too far for now, a single email address you keep only for co-parenting works too.
- Tell them once, in writing. Keep it short and give a date. There is an example below that you can copy.
- Mute first, then block if you need to. Muting stops the notifications but still lets messages arrive, so nothing is lost while the change beds in. If messages keep coming, blocking is a reasonable next step.
- Keep one route for real emergencies. Agree that a phone call means something urgent about the children, such as illness, an injury or a missed collection, and that everything else goes in the agreed channel.
- Reply only in the agreed channel. If a text still arrives, answer the substance where you said you would, with a short line such as: I have replied in ParenThing.
- Keep your side calm and factual. Brief, informative, friendly and firm. One topic per message, no comment on them as a person, and nothing you would mind a stranger reading aloud.
Expect a few weeks of testing. The boundary holds because you keep to it, not because the first message was perfect.
A message you can send
From next Monday, I will only reply about the children on ParenThing. It keeps the calendar, costs and messages in one place for both of us, and it is free for you to use. I will send you an invitation now.
If there is a genuine emergency involving the children, phone me.
Change the day and the app to suit you. What matters is that it names one channel, gives a date, explains the reason in one sentence and keeps an emergency route open. It does not argue, and it does not ask permission.
What one channel gives you in ParenThing
ParenThing was built for exactly this move, so it is worth being specific about what it does and does not do.
- Messages that stay calm. Every message is checked for tone before it sends, so a heated draft gets a chance to be rewritten before it lands. That works for both of you.
- A record that cannot be rewritten. Messages are kept exactly as they were written. They cannot be edited or deleted once sent, and each one carries a mark showing it has not been changed.
- Everything about the children together. The shared calendar with handovers, documents and tasks sit alongside the messages, and costs and payment requests are there on Premium, so nothing is scattered across chats.
- Professionals only if you both agree. A mediator or solicitor can see the family's record only when both parents agree, and either parent can end that access on their own.
- You choose when to open it. It is one place you go to when you are ready, rather than four that find you.
ParenThing is free for both parents to use. Premium is €12.99 a month or €119 a year, and it is one subscription for the whole family rather than one each. If you are wondering how a record like this is treated later, we have written separately about whether co-parenting app messages count as evidence. It is always for a court to decide what it accepts.
If they will not move
Some co-parents will not use the app, or will keep messaging everywhere else for a while. That is common, and it does not mean the boundary has failed.
Keep your replies in the channel you named, keep the emergency route open, and keep your own record anyway. We have written about what to do when your co-parent refuses to use a co-parenting app, and about using a co-parenting app when you are the only one on it, which is more useful than it sounds.
If communication has stopped altogether, rather than simply moved, read co-parenting when the other parent will not communicate. A family mediator can often help restart a conversation that has broken down, and mediation is available in every jurisdiction we cover.
If you feel unsafe
Sometimes the messages are not just constant but frightening. Coercive control is a criminal offence in Ireland and across the UK, and it does not have to involve violence. If what you are dealing with feels controlling rather than merely difficult, you do not have to manage it alone.
Specialist services can help you plan safely, including whether and when to block, because cutting off contact can change how someone behaves. Our support pages list them for Ireland, England and Wales, Scotland and Northern Ireland. If you are in immediate danger, call 999 or 112.
Common questions
Is it legal to block my child's other parent?
Yes. In Ireland and the UK no law requires you to stay reachable on every channel. Keep one agreed way to communicate about the children open, and follow any court order or written agreement that sets out how you communicate, including any emergency phone number it names.
Will blocking my co-parent look bad if we end up in court?
Moving everything about the children to one agreed channel and keeping to it is generally seen as reasonable. Cutting off every way of communicating about the children is different and can count against a parent. If you have a court order or are heading for court, get legal advice on your own situation.
Should I mute or block my co-parent?
Start by muting. It stops the notifications while messages still arrive, so nothing is lost while the change settles. If messages keep coming on channels you have said you will not use, blocking is a reasonable next step, as long as the agreed channel and an emergency route stay open.
What counts as an emergency?
Something urgent about the children that cannot wait for the agreed channel, such as illness, an injury, or a missed or changed collection on the day. Agree it in advance, and if the emergency route starts being used for everyday things, reply in the agreed channel instead.
What if my co-parent will not use a co-parenting app?
You cannot usually make them, but you can still choose one channel, such as email, and keep to it. Keep your own calendar and record in the app anyway, and leave the invitation open rather than chasing.
