You found a co-parenting app, set up your account, sent the invite, and nothing happened. Or your ex said it outright: they're not downloading it. Now you're stuck wondering whether there's an app for co-parenting without your ex joining, or whether there's any way to make them join at all.
The answer depends almost entirely on one thing: whether a court order requires the app. This guide walks through both situations, gives you sample wording that keeps you looking reasonable, and explains what you can do on your own, starting today, no matter what your ex decides.
Can you make your ex join a co-parenting app?
Not on your own. A co-parent who won't download the app can't be forced to by the other parent. Without a court order, joining an app is voluntary, so all you can do is ask and make it easy to say yes. With a court order that names an app, using it isn't optional for either parent, and if your ex refuses, the court can be asked to enforce or change the order.
That gives you two very different playbooks:
- The app is court-ordered: keep following the order yourself, document the refusal, and get advice about enforcement or modification.
- There's no order: find out why your ex is refusing, offer reasonable options, and set up a way to handle your side that doesn't depend on them.
If you're wondering whether you could ask a court to require an app in the first place, our guide to court-ordered co-parenting apps explains how that generally works.
If the app is court-ordered and your ex won't use it
Keep following the order exactly, even though they aren't. Their refusal doesn't release you, and your consistency is part of your record.
- Keep using the app. Send required information through it on schedule, even if your messages go unread.
- Use other channels only as the order allows. If it permits calls or texts for emergencies, use them for emergencies only.
- Log the refusal. Note each date your co-parent said they wouldn't use the app, ignored an invitation, or sent messages outside it. Save those messages.
- Don't retaliate. Don't withhold parenting time or information because they aren't using the app. That can create a problem for you.
- Get advice. A local attorney or your court's self-help center can explain your options, which may include asking the court to enforce the order (see our guide to contempt in custody cases) or to change the communication terms (see how to modify a custody order).
Sample message (sent through the ordered app, and by text if the order allows)
"Our order requires us to use [app] for communication about [child], so I'll keep sending updates there. Pickup this Friday is at 5:00 at the school. If you have trouble accessing the app, let me know through it and I'll try to help."
If there's no order: find out why your ex refuses
When an ex refuses a co-parenting app, there's usually a reason, and some reasons are fixable. Before you push harder, think about which one fits.
| Common reason | What might help |
|---|---|
| Cost | Point out free trials and fee waivers, or suggest a free method like email |
| Feeling monitored or controlled | Offer a simpler channel with clear ground rules |
| Not comfortable with technology | Email or a shared calendar they already use |
| Doesn't want a record | You can't change that; focus on keeping your own records |
| Ongoing conflict | Raise communication methods in mediation |
Cost is a bigger issue in 2026 than it used to be. As of October 2026, AppClose has charged a subscription since January 1, 2026, with a 60-day free trial (AppClose pricing). TalkingParents has required a paid plan since March 30, 2026, and each parent has their own plan (TalkingParents pricing). OurFamilyWizard bills each parent yearly, from $110 (OurFamilyWizard plans and pricing). All three offer fee waivers or free accounts to parents who qualify, and each has its own tone tool on at least one plan. A co-parent who would have joined a free app may balk at paying, so check the current terms before you ask.
How to ask without starting a fight
Keep the request short, focused on the kids, and easy to say yes to. Offer a choice, not an ultimatum.
Sample request
"I'd like us to keep communication about [child] in one place so nothing gets missed. Would you be open to [app]? It has a [60-day / 30-day] free trial, and the company offers a fee waiver if you qualify and cost is a concern. If you'd rather not use an app, email works for me too. Let me know which you prefer by [date]."
- Ask once, in writing, then follow up once if there's no answer.
- Accept a reasonable alternative, like email, instead of insisting on your first choice.
- Don't threaten court in the request. If you later need the court, your calm request will speak for itself.
- Save the request and any reply in your records.
Co-parenting without your ex joining an app: what you can do alone
Quite a bit. You can't build a shared record alone, but you can keep your side clean, complete and organized.
- Choose one written channel and stick to it, usually text or email, so your history isn't scattered.
- Confirm calls in writing. After a phone call, send a short summary: "To confirm what we discussed, pickup moves to 6:00 on Sunday."
- Keep messages brief and factual. Answer the logistics and skip the bait.
- Log exchanges, schedule changes and missed visits as they happen, with dates and times.
- Back up your messages regularly, and keep copies somewhere your co-parent can't access.
- Use a one-sided tool to organize all of it. Our explainer on one-sided co-parenting apps covers what they can and can't do.
Should you ask the court to order an app?
Sometimes parents do, especially when communication keeps breaking down. Whether it's a good idea depends on your situation, and no one can predict how a particular judge will respond.
Things worth thinking through before you raise it, whether in mediation or in a request to the court:
- What problem would the app solve? Missed information, disputes about who said what, or hostile messages are different problems with different fixes.
- Who would pay? With the major shared apps now paid, cost may come up. Know the current prices and fee waiver options before you ask.
- Would your co-parent actually use it? An order helps, but a parent who refuses an app today may still be difficult inside one.
- Is there a simpler request? Response-time rules, topic limits or written-only communication can sometimes address the same concern.
- Is there a history of abuse? If so, talk with a domestic violence advocate or attorney about the safest communication arrangement.
Mediation is often the easiest place to raise this, because you can agree on the method, who pays and the ground rules together. A local attorney or your court's self-help center can explain how to make a formal request if mediation isn't an option.
How Custody Commander helps when your ex won't join
This is the situation it was built for. It's one-sided: you sign up alone, your ex never joins, installs or pays for anything, and you don't need a court order or their permission to use it. Your records stay private until you choose to share them with a named attorney or advocate.
It doesn't send messages and isn't a shared messaging platform, so it won't create the shared record a two-sided app does. Here's what it does do:
- Checks your drafts before you send them. Comms Guard flags tone, escalation, admissions and oversharing, suggests a calm BIFF rewrite, and keeps a timestamped log of each checked message. You copy and send it yourself, by text, email or a court-ordered app.
- Turns texts into a court-ready PDF log, chronological and Bates-numbered, with an index page.
- Builds your timeline of exchanges, missed visits and incidents, linked to the proof.
If an app is court-ordered, it works alongside it. Every account starts with a 14-day free trial of everything, no credit card; after that, the free tier includes 1 case and 10 evidence items with watermarked PDF exports and no AI features.
