How to Keep a Custody Log You’ll Actually Stick With (Free Template)

If you’re trying to work out how to keep a custody log, it’s usually because the same things keep happening and nobody remembers them the same way. A pickup runs 40 minutes late. A school email never gets forwarded. A reimbursement has been “coming” for three months. Told one at a time, each sounds petty. Written down the same way every time, they become facts you can count, or proof that things are mostly working, which is just as worth knowing.

This guide shows you what to record, how to fill in each field of a co-parenting log, what a good week of entries looks like, and how to keep the log fair enough that it keeps its value if a lawyer, mediator or judge ever reads it. A free co-parenting log template (PDF and Excel) is partway down, so you can start tonight.

What is a custody log, and how is it different from a journal?

A custody log, often called a co-parenting log, is a structured, repeatable record of the routine facts of shared parenting. A journal tells the story; a log counts things.

Every entry in a log uses the same fields, so you can sort, total and summarize them later. “He’s always late” becomes “late 9 of the last 20 exchanges,” or “late twice,” which is just as useful to know. A journal is where you write a few sentences about a hard conversation or something worrying your child said. Many parents keep both: the log for facts that repeat, and a custody journal for moments that need description.

• It replaces memory with data. In six months you won’t remember which Sunday was late. The log will.
• It keeps you calm. Checking the log before replying to an accusation keeps your answer factual.
• It saves professional time. A lawyer or mediator can absorb months of history from a one-page summary instead of a camera roll.
• It keeps you honest with yourself. Sometimes the log shows a problem is smaller than it felt.

What should you record in a co-parenting log?

Record the parts of shared parenting that repeat and affect your child. Skip everything else.

• Exchanges: scheduled time and place, when each parent actually arrived, and anything notable. Log the smooth ones too.
• Schedule changes: who asked, for what, when, the answer, and any make-up time.
• Communication: date, topic, channel, and whether and when a reply came. Note where the message is saved instead of pasting it in.
• Your child’s needs: school notices, appointments, illnesses, activities, and who told whom.
• Shared expenses: item, amount, share owed, the date you asked for reimbursement and the date it was paid.
• Calls or video chats with your child: if your order provides for them, whether they connected and roughly how long.
• Incidents: anything out of the ordinary that affected your child, described in plain facts.

If late or missed exchanges are the main problem, our guide to documenting missed visits goes deeper on that one category.

How to fill in the custody log template, field by field

The free template below is a day-by-day log for exchanges, communication, your child’s needs and incidents. Whether you use it or build your own spreadsheet, these are the fields that make a log useful later.

1. Date and day of the week. Write the full date plus the day (09/25, Fri). The day makes patterns like “every other Sunday” jump out.
2. Scheduled time vs. actual time. For exchanges, put the time from your order next to the time each parent actually arrived. Use the order’s wording, not your memory of it.
3. Category. One short label per entry: Exchange, Change request, Communication, Child’s needs, Expense, Call or Incident. Consistent labels are what let you filter later.
4. What happened. One or two sentences a camera could have recorded. “Arrived 6:42 p.m. Text at 6:15 said ‘running late.’” Not “showed up whenever he felt like it.”
5. Who was there. You, the other parent, your child, a teacher, a coach, a grandparent. Witnesses matter more than adjectives.
6. Effect on your child. Only what you saw, or what your child said in their exact words. Leave it blank when there’s nothing to note.
7. Proof and where it’s saved. “Text, screenshot saved 9/27,” “receipt photo,” “school email 9/29.” The log points to the proof; it doesn’t replace it.
8. Follow-up. Anything still open: a reimbursement due, an unanswered question, make-up time to schedule.

Notice what’s missing: opinions, guesses about motives, and anything about the other parent’s life that doesn’t touch Maya. Notice what’s included: an on-time exchange and an agreed swap. Those entries are what make the late one believable.

How to keep a custody log going when life gets chaotic

Make it small, make it a habit and keep it in one place. A log that takes two minutes a day survives a hard month; one that takes twenty doesn’t.

1. Pick one home for the log. The spreadsheet, a bound notebook or one app. Not all three.
2. Load the schedule first. Copy every exchange from your order for the next few months, so the “scheduled” column comes from the order.
3. Use short codes. OT (on time, within 15 minutes), L (late, with minutes), NS (no-show, no notice), CN (canceled with notice). Put the key at the top.
4. Enter it the same day. Set a phone reminder an hour after your usual exchange times.
5. Back it up weekly. Save a dated copy somewhere private that the other parent can’t access.
6. Review for ten minutes on Sundays. Totals for the week, open requests and unpaid reimbursements.

How do you keep a co-parenting log fair and credible?

Hold both parents to the same rules, including yourself. A log is only as believable as its most one-sided entry, and anyone reading it closely will notice if your own late arrivals are missing.

• Record your own late arrivals, cancellations and change requests, with the reason.
• Record the reason the other parent gives, without commentary, even if you doubt it.
• Measure against the order’s actual terms. If it says “approximately 6:00,” don’t log 6:05 as a violation.
• Use neutral words: “arrived 6:45,” not “couldn’t be bothered to show up.”
• Add a dated correction instead of changing an old entry.

How do you turn months of entries into a summary?

Summarize by period and category, and make every number traceable to dated entries. A summary is what makes months of rows readable in two minutes.

The summary states counts, points to the dates behind them and includes the writer’s own lapses. That’s what makes it credible. If your log is mostly about late or missed handoffs, our guide on tracking late drop-offs and pickups shows how to present that pattern.

The hard way vs. letting Case Builder keep your timeline

The template works, and plenty of parents keep a paper or spreadsheet log for years. The hard part comes later. When a hearing or a lawyer’s consultation is on the calendar, you have to match each row to its screenshot or receipt, retype the important entries into a timeline in Word, number the proof and rebuild it all when something new happens.

Case Builder is built for that second half. It keeps a master timeline that collects dated items from the evidence, messages and hearings you add, each one linked to its proof. You can filter it, export it to PDF or Word, and keep one issue workspace per point you’re making, such as “late exchanges,” with the related evidence mapped to it. When you hire help, it generates an attorney handoff packet with the Evidence Index, the timeline and per-issue summaries. You can see how the timeline and issue workspaces fit together.

Every new Custody Commander account starts with a 14-day free trial of everything, no credit card. After that, the free tier keeps 1 case and 10 evidence items with organizing, tagging, search and a watermarked PDF export (no AI), so you can keep your template log and add only your key proof.

What goes wrong with custody logs?

Most logs fail because they start late, try to capture too much or drift into opinion.

• Starting the week before a hearing. A log is strongest when it was clearly kept all along.
• Too much detail. If each entry takes ten minutes, you’ll quit. Keep the log short and put stories in the journal.
• Counting trivia. Logging a three-minute delay as a violation makes the whole record look petty.
• One device only. A log that lives only on your phone disappears with the phone.
• Letting your child see it. Keep it private, and never use it to show your child what the other parent “did.”

If you’re working with a lawyer, even on a limited basis, ask how they’d like the log formatted before you build months of entries. A licensed attorney where you live can also tell you whether your court has preferences for how parenting records are presented. And if you’d rather keep your log on your phone, our guide to choosing a free app to log custody issues compares the options.
