Understand what each term actually means in a co-parenting context

No contact means zero voluntary communication: no texts, no calls, no social media, no showing up. For people without children, it is a clean line. For co-parents, it is not a legal option unless a court order or documented safety concern supports it. Attempting full no contact when you share custody will almost certainly put you in violation of your parenting agreement and hand your ex grounds for a legal complaint.

Low contact is the realistic alternative. It means communication is limited to child-related logistics only, conducted through a defined channel, at defined times, with no small talk and no emotional content. Think of it as a business relationship where the only agenda item is your children's schedule, health, and school.

The distinction that matters: low contact is not just talking less. It is restructuring every interaction so it has a fixed purpose and a clear endpoint. 'Can you take her Thursday instead of Friday?' is low contact. 'I've been thinking about what you said last month and I want to talk' is not. One sentence, one topic, one reply expected. That is the working definition.

Set up a single dedicated communication channel and use nothing else

Pick one channel for all co-parenting communication and stick to it exclusively. The most common and legally useful options are a co-parenting app (TalkingParents, OurFamilyWizard, and AppClose are the main ones), a designated email address, or text on one specific number. Courts favor documented platforms because the record is timestamped and cannot be deleted.

Once you choose the channel, you stop communicating everywhere else. That means if they text your personal number, you do not reply there. You reply in the designated app, or not at all until you can. If they email from a personal account about pickup, you copy the relevant information into the co-parenting thread and respond there. This sounds rigid because it is. Rigid is what protects you.

Why this step matters so much: when you have one channel, you also have one place to check. You are not scanning three inboxes and a voicemail wondering if something came through. Research consistently shows that continued, unstructured contact with an ex prolongs distress significantly. A structured channel does not eliminate contact but it removes the ambient presence of them from your daily life, which is most of what wears people down.

Write a communication protocol before you need it

A protocol is a one-page document, ideally agreed on by both parties, that answers four questions: What topics are in scope? What is the expected response window? What happens in a genuine emergency? What format do messages take?

In scope topics typically include: school schedules and events, medical appointments and medication, extracurriculars, pickup and dropoff logistics, and major decisions that require both parents. Out of scope: your feelings about the relationship, grievances about the past, anything that would require a longer conversation than three exchanges.

Response window: 24 hours for non-urgent logistics is reasonable and court-defensible. Emergencies involving the child's immediate safety are the one exception where any channel and any time is appropriate.

Message format: short, factual, no emotional language. 'Maya has a dentist appointment Wednesday at 3pm, I will pick her up from school' is a complete message. Nothing more is required. If you find yourself writing and deleting the same message four times trying to get the tone right, that is a signal the message has crossed into emotional territory. Draft it, save it, send it tomorrow.

Handle the moments that want to pull you back into full contact

The handoffs are the hardest part. You are standing in your driveway, the kids run inside, and suddenly it is just the two of you for thirty seconds. Research on ambivalence is sharp on this point: the wanting and the dread you feel in those moments are not a sign you should say more. They are what staying in even low contact produces. The mixed feelings feed on contact, they do not resolve it.

Practical rules for handoffs: keep them under five minutes, have the kids present if possible, say what is functionally necessary and nothing more. 'She has a math test Friday, I already packed her lunch for tomorrow.' Done. If your ex tries to extend the conversation, a flat 'I'll send you a message about that' is not rude, it is the protocol working.

For the holidays, school events, and birthday parties where you are both present: arrive separately, leave separately, sit in different sections if the venue allows it. You do not have to be hostile. You have to be brief. The distinction matters because your children are watching how you treat the boundary, not just that it exists.

We go into the research on why continued contact extends distress in more detail in our piece on finding closure without no contact being possible, which covers what to do when you cannot cut off completely.

Audit the system every 90 days and adjust what is not working

Low contact is not a set-it-and-forget-it arrangement. Kids' lives change, school years end, new schedules start, and what worked in September may not work by January. Build in a review point every quarter.

At each audit, check three things. First, is the communication channel still working, meaning are messages being sent, received, and responded to within the agreed window? If not, document what broke down and propose an adjustment. Second, are you still holding the topic boundary? If the last month of messages includes anything that is not logistics, that is where the protocol eroded and that is where you tighten it. Third, how are the kids doing? Their adjustment is the actual metric here. If drop-offs have gotten harder or their behavior has shifted, the communication structure between you and your ex is one of the variables worth examining.

If the system keeps breaking down despite adjustments, the next step is a parenting coordinator, a neutral third party a court can appoint to mediate disputes without requiring full litigation. They are not therapists and they do not adjudicate blame. They make decisions about logistics when the two of you cannot, which is exactly the kind of structure that makes low contact sustainable long term.
