The best custody app when the other parent won’t use one (2026)

Full disclosure: we make Custody Proof, one of the options below. So yes, we are biased. This guide says plainly when a different kind of tool is the better choice. It compares kinds of tools; for head-to-heads with specific apps, see our comparisons.

Short version: a shared co-parenting app is a two-person tool. It works when both parents log in, read messages, answer requests and enter their own information. When the other parent will not sign up, signs up and never opens it, or uses it mainly to start fights, the app does not fail loudly. It just quietly stops recording the things you need.

This guide is for that situation. The good news is that the most important record in a custody case does not need the other parent at all. Your nights, the exchanges that went wrong, what you paid for, what you were told and when: all of that is yours to write down, and you can start tonight without anyone’s permission.

TL;DR

When the other parent will not participate, the deciding question is simple: does this tool still work if only you use it? Shared apps mostly do not. Your own record does. Keep using any channel a court ordered, and keep your own record next to it.

Best record that works with one parent: Custody Proof (ours).
Best when a court ordered a shared platform: that platform, used exactly as ordered, even if you are the only one writing.
Best for proving you tried to communicate: your phone’s texts and emails, exported and saved regularly.
Best if you already have an attorney with a system: your attorney’s own intake process.

Why a shared app breaks when one parent opts out

Most shared co-parenting apps are built around a conversation. The calendar is shared, so it is only accurate if both parents keep it accurate. Expense requests only work if the other parent opens them. Schedule-change requests only mean something if someone answers. With one parent missing, what you are left with is half a conversation and a calendar only you maintain.

That half-conversation is not worthless. Unanswered messages can show you tried, and if an order requires a particular platform, you should keep using it. But it is a weak home for your own record. Your notes about a missed exchange, your photos, your count of nights: none of that belongs somewhere the other parent can read, and none of it should depend on whether they ever log in.

The fix is to separate the two jobs. Communication goes wherever the order or your agreement says. Your record lives somewhere private that works whether or not the other parent ever participates. We wrote more about this split in why co-parenting apps fail.

What you can document without the other parent

Your own time. Every overnight and daytime visit, the day it happens.
What went wrong. Missed or late exchanges, refused handovers, changes made without notice.
What you sent. Every message you sent and whether it was answered, with screenshots.
What you paid. Receipts for costs the order may split, with the date you asked to be reimbursed.

1. Custody Proofours

Best for: a complete record kept by one parent, with no cooperation needed from the other
Price: $14.75/month or $144/year (Case Builder with the AI assistant: $29/month or $278/year). 30-day money-back guarantee on your first charge
Who can see it: Only you. The other parent is never invited and never notified.

This is ours, and this situation is the reason it exists. One parent subscribes. The other parent never gets an account, never gets an invite, never gets a notification and cannot see anything you record. Nothing in it waits for them. Their refusal to participate changes nothing about how well it works.

You set your schedule up by typing it in plain words or uploading your custody order, and you confirm the pattern before anything saves. It never guesses which parent you are or which week is week one. Then you log what actually happened: one tap for a normal overnight, a violation flag and a sentence when an exchange goes wrong. The Plan vs. Actual view shows every day that differed from the schedule, and you can confirm the record through yesterday once it is right.

Screenshots of unanswered messages go into the encrypted, timestamped evidence vault, tagged with the children they are about. Costs go into the expense ledger with receipts and a running reimbursement balance. If you have been keeping records in a shared app the other parent abandoned, you can bring your own custody history in from a calendar export (.ics), and there are copy-paste prompts for other formats. Your own records only.

Where it falls short: It cannot make the other parent read anything or reply. It has no messaging and no shared calendar, so if you need a channel to reach them, or an order requires one, you still need that channel.

2. The shared platform your order names

Best for: staying compliant when a court ordered a specific communication app
Price: Varies by product, often per parent and by feature tier
Who can see it: Both parents, and often invited professionals

If your order requires a shared platform, keep using it exactly as ordered, even if the other parent never answers. Send your schedule questions and expense requests there. A record of messages sent and never read can matter, and walking away from an ordered platform because the other parent did is a risk you should discuss with your attorney first.

Just do not let it be your only record. It shows what was said between you. It does not show what happened at the exchange, and it is not where your private notes belong.

Where it falls short: With one parent absent it holds half a conversation, and everything you write there can be read by the other parent whenever they choose to look.

3. Your phone’s texts and emails, exported regularly

Best for: showing that you reached out, when the other parent communicates only by text or not at all
Price: Free
Who can see it: Only you, until you share them

Many parents whose co-parent refuses a shared app end up communicating by text anyway. Those threads are part of your record. Once a month, screenshot or export the month’s messages, name the file by date, and save it somewhere that is not only your phone. Phones get lost, replaced and reset.

If no communication is ordered and the other parent only answers texts, this is honestly the right channel for reaching them. Just keep it about logistics.

Where it falls short: It covers what was said, not what happened, and nothing counts nights or organizes it by incident.

4. Your attorney’s own intake process

Best for: parents who already have counsel with a preferred format
Price: Part of your legal fees; ask your attorney
Who can see it: You and your attorney’s office

Some attorneys have their own forms, logs or document portals, and want records in a particular shape. If yours does, that format wins. It is pointless to keep a beautiful record in one system and then retype it into another the week before a hearing.

Ask early. If they are happy with an exported PDF or spreadsheet, keep your day-to-day record wherever you will actually keep it up.

Where it falls short: It usually is not built for daily logging, so you may still need somewhere to write things down the day they happen.

5. A bound paper journal

Best for: starting tonight, with nothing to install and no one to invite
Price: A few dollars
Who can see it: Whoever has the notebook

If you have been waiting for the other parent to join something before you start keeping track, stop waiting. A bound notebook, one dated line per day, written the same day and never rewritten, works on its own from the first entry.

Where it falls short: No attachments, no counting, and it all has to be typed up later.

Our pick

If the other parent will not use a shared app: stop trying to build your record somewhere that needs them. Keep communicating however your order or agreement says, and keep your own private record next to it. Custody Proof is built for exactly this, a record one parent keeps that works the same whether or not the other parent ever participates.

If a court ordered a shared platform, do not abandon it. Use it as ordered and keep your own record as well. If your attorney already has a system, use theirs and keep your daily notes wherever you will keep them up. For the difference between a shared channel and your own record, see CustodyProof vs co-parenting apps.

What we’d do today

Check your order for any required communication platform or method. If there is one, keep using it as written.
Screenshot every unanswered message, request or invite from the last three months and save them in one dated folder.
Write down your schedule as the order states it, then log the last two weeks of what actually happened, marking anything approximate.
Pick one place for your own record that does not need the other parent, and make tonight’s entry there.
Ask your attorney what they want: “The other parent will not use the app. What should I keep, and in what format?”

Questions

Can I use Custody Proof if the other parent refuses to sign up for anything?

Yes. That is what it is built for. One parent subscribes, and the other parent never needs an account, never gets an invite and never sees anything you record.

The court ordered a shared app and the other parent ignores it. Can I stop using it?

Do not stop on your own. Keep using the platform as the order says, even if you are the only one writing, and ask your attorney about the other parent not participating. Keep your own private record alongside it.

Is a one-sided record worth anything?

A dated record written the day things happen is useful to your attorney whether or not the other parent kept one. Whether and how it is used in court is a question for your attorney.

Can I move my history out of the shared app?

If the app lets you export a calendar file, Custody Proof can import your own custody history from it, and there are copy-paste prompts for other formats. Only your own records, never the other parent’s account.

Does the other parent get notified when I log something about them?

No. Custody Proof never contacts the other parent. There is no messaging, no shared calendar and no notification of any kind.
