A co-parenting log is the simplest evidence tool you can build, and most parents either skip it or overcomplicate it. This page gives you a free co-parenting log template you can copy in under a minute, the exact columns a family court expects to see, a filled-in example, and the rules that keep the log credible if it ever reaches a judge.

What a Co-Parenting Log Is and What to Record
A co-parenting log is a running, dated record of the practical facts of shared parenting: exchanges, communications, schedule changes, and anything that affects the child. It is narrower than a full custody journal and broader than a single message thread. Think of it as the spreadsheet version of your case — one row per event, every row dated.
Record these events as they happen:
- Exchanges — scheduled time, actual time, location, the child’s condition at handoff
- Missed or late visits — what was scheduled, what happened, the reason given
- Communications — requests, refusals, agreements, and notable messages
- Schedule changes — who asked, what was agreed, whether it was confirmed in writing
- Expenses — shared costs, who paid, what was reimbursed
- Incidents — anything affecting the child’s safety or well-being, recorded as plain fact
Keep each entry short and factual. The log is a quick-reference timeline; longer narrative observations belong in a custody journal, which the log can cross-reference.
The Free Co-Parenting Log Template
Copy the table below into a spreadsheet (Google Sheets, Excel, or Numbers) or print it as a paper form. These seven columns cover what a family court expects without overloading you with fields you’ll abandon by week two.
| Date | Day | Time | Event Type | What Happened (facts only) | Witness / Proof | Exhibit Ref |
|---|---|---|---|---|---|---|
Column-by-column: what each field captures
- Date — full date, including the year (e.g.,
2026-05-14). Sortable formats help when you print a multi-month log. - Day — day of the week. Patterns (every other Friday late) jump out faster with this column.
- Time — the precise time. “6:14 PM” carries more weight than “evening.”
- Event Type — a short tag: Exchange, Late, Missed, Message, Schedule Change, Expense, Incident. Tags make the log filterable.
- What Happened (facts only) — one or two sentences of observable fact. Quote exact words when language matters. No adjectives, no conclusions.
- Witness / Proof — who else saw it, or what backs it up (“text saved,” “photo 6:15 PM”).
- Exhibit Ref — a letter or number tying the row to a saved file in your evidence folder.
A filled-in example row
| Date | Day | Time | Event Type | What Happened (facts only) | Witness / Proof | Exhibit Ref |
|---|---|---|---|---|---|---|
| 2026-05-14 | Thu | 6:14 PM | Late | Scheduled exchange 6:00 PM at City Library. Other parent arrived 6:14 PM. Child had backpack and jacket, calm. | E. Park present | B-14 |
The example reads cleanly to a stranger: it is dated, timed, specific, and points to proof. That is the whole standard.
Printable vs. Digital: Which Format to Use
Both formats hold up. The right one depends on your situation, not on which is “better.”
| Factor | Printable (paper) | Digital (spreadsheet) |
|---|---|---|
| Setup speed | Print and go | Two minutes in Sheets |
| Sortable / filterable | No | Yes |
| Tamper-evidence | Strong (ink, bound pages) | Strong if version history is on |
| Court exhibit prep | Already physical | Export to PDF, then print |
| Backup | Photograph each page | Cloud sync automatic |
| Best for | Low-conflict, occasional entries | High-conflict, frequent entries |
A practical default: keep the log digitally in a spreadsheet with version history turned on, and print a clean copy quarterly for your exhibit binder. If a court order or a no-tech preference points you to paper, use a bound notebook with numbered pages rather than loose sheets that can be reordered.
Whichever you choose, pick one and stay with it. Switching formats midway is one of the easiest ways for the other side to question your record.
How to Keep Your Log Court-Ready
A log only helps if a court will trust it. Four habits make the difference:
- Log contemporaneously. Enter events the same day. Records made close to the event carry far more weight — the principle courts apply when authenticating evidence under Federal Rule of Evidence 901 and its state equivalents.
- Stay factual and balanced. Record cooperative exchanges alongside the difficult ones. A log that only catalogs failures reads as advocacy and loses credibility.
- Back it up. Keep one copy off your primary phone — cloud storage or a trusted person. Export to PDF monthly.
- Cross-reference proof. Tie rows to texts, photos, and records using the Exhibit Ref column. The log becomes a timeline that points to evidence rather than standing alone.
A log is most powerful as part of a complete file. The custody evidence checklist covers how to assemble the binder, timeline, and supporting records the log connects to. And because most of what you’ll log is communication, the method in documenting co-parenting communication for court pairs directly with these rows.
Common Logging Mistakes That Weaken It
- Backfilling. Adding entries weeks later and dating them as if contemporaneous. Once discovered, it taints the whole log.
- Editorializing. “He was impossible again” tells a judge nothing and signals bias. State the observable fact instead.
- Cropping the proof. Screenshots that hide context invite the argument that you’re concealing something. Save full threads.
- Recording calls illegally. Some states require all-party consent. An unlawful recording can be excluded and used against you — check your state’s law first. See the rules on text messages and recordings in court.
- Logging only the bad days. Balance is credibility. Note the neutral and cooperative moments too.
- Involving the children. Never ask a child to gather, witness, or relay log content. Courts treat that as a negative factor.
Frequently Asked Questions
What should a co-parenting log include?
Each entry should capture the date, day, time, event type, a short factual description of what happened, any witness or proof, and a reference to the saved evidence. Log exchanges, missed or late visits, communications, schedule changes, shared expenses, and any incident affecting the child. Keep entries short, specific, and free of opinion.
Is a co-parenting log admissible in court?
Often, when it is kept contemporaneously and can be authenticated. A factual, dated log can refresh your memory while testifying and, in some cases, be entered as a record. Admissibility depends on your state’s rules of evidence, so confirm local practice with your attorney before relying on it at a hearing.
What is the best app for a co-parenting log?
For a simple log, a spreadsheet in Google Sheets or Excel with version history enabled works well and exports cleanly to PDF. For high-conflict situations, dedicated apps like OurFamilyWizard, Talking Parents, and AppClose store entries with timestamps neither parent can edit and provide custodian declarations that help with authentication.
How do I make a custody log?
Copy the seven-column template on this page into a spreadsheet or print it as a form, then add one row per event the same day it happens. Use the columns for date, day, time, event type, observable facts, proof, and an exhibit reference. Back the file up and keep it factual and balanced.
What’s the difference between a co-parenting log and a custody journal?
A log is a structured, one-row-per-event table for quick scanning and pattern-spotting. A journal allows longer narrative entries for complex incidents. Many parents keep both: the log for the timeline, the journal for detail. See the custody journal guide for the longer format.
How often should I update my co-parenting log?
Enter each event the same day, or the next morning at the latest. Contemporaneous entries are stronger evidence and more accurate. If you miss a day, label the late entry honestly rather than dating it to look contemporaneous.
