Is a custody calendar a record of parenting time?

Not on its own. A custody calendar sets out the schedule: whose weekend it is, when the exchange happens, which parent has the holiday. That is a plan for the future, and a good one saves a lot of confusion.

From a family law practice
“A child custody calendar or timesharing schedule is a detailed plan for when the child will spend time with each parent.”
McMichen, Cinami & Demps, family law practice, Florida Published on the firm’s blog: What Is a Child Custody Calendar?

The key word is plan. A record answers a different question: what actually happened on a given day. Your child may have stayed an extra night, an exchange may have run an hour late, a weekend may have been swapped by text. The calendar still shows the original schedule unless someone changes it, and if someone does, it shows only the latest version.

What does a shared custody calendar do well?

For planning, that is most of what you need. The trouble starts when the same calendar is asked to prove something later.

What can a shared calendar not show?

Calendar export files in the standard iCalendar format can include when each event was created and when it was last modified. That is useful, but it is the last change only, and the file sits in an account you control, so it rests on your word as much as the calendar does.

Who can change a shared custody calendar?

Anyone you give edit access. On Google Calendar, sharing settings include permission to make changes to events. On iCloud Calendar, a shared calendar can be set to view only or view and edit. With edit access, either person can move or delete an event.

That is the right design for planning, because plans change. It is the wrong design for a record. A record that the other parent can edit is not a record of your days, and a calendar where an event can quietly move from Saturday to Sunday cannot settle a dispute about which day it was.

Documented is a record of your own days, kept by one parent. It does not need the other parent to use it, and nobody else can edit it. Our guide to tamper-evident records explains why showing a change matters more than claiming none is possible.

Can a custody calendar be used in court?

It can be, but the judge decides how, and the rules vary by state. Two federal rules show the usual issues, and many states have similar ones.

Showing what it is. Under Federal Rule of Evidence 901, the person offering an item must produce evidence sufficient to support a finding that the item is what they claim it is. For a calendar, that usually means explaining who kept it, how, and when entries were made. A shared calendar both parents could edit makes that explanation harder.

Summarising many days. Federal Rule of Evidence 1006 allows a summary, chart or calculation to prove the content of voluminous records that cannot be conveniently examined in court. The underlying records must be made available to the other side. A parenting time tally is that kind of summary, and it is only as good as the day-by-day entries beneath it.

From a family law attorney
“All calendars, expenses, photos and messages can be kept and recorded for future reference and may be helpful if there is future litigation.”
Emily Yu, associate attorney, Meriwether & Tharp, LLC, Georgia Published on the firm’s blog: Parenting Websites Can Help Parents Sharing Child Custody

Note the word kept. A calendar becomes useful later because someone recorded things in it as they happened, not because the schedule was in it. Our guide on parenting time percentage covers how a tally is worked out. This is general information, not legal advice, so ask your attorney how your court treats a parent’s calendar.

How do you use a calendar as a custody record?

If a calendar is what you have, these habits make it more useful:

  1. Keep your own calendar for the record. Use the shared one for the plan, and a separate one that only you can edit for what actually happened.
  2. Add to it the same day. The closer an entry is to the event, the more it is worth.
  3. Write the actual times. “Exchange at the school, 5:42 pm” says more than a 5:00 event left unchanged.
  4. Note changes as changes. If a weekend is swapped, keep the original event and add a note about the swap, rather than dragging the event to a new day.
  5. Write facts about your own day. What you did with your child, where, and when. Leave out opinions about anyone.
  6. Save the messages behind each change. A text agreeing to a swap belongs with the entry that records it.

That is a lot of discipline to ask of a calendar, which is the honest case for a dedicated record. Our guide on documenting missed handoffs and late pickups covers what a useful entry about an exchange looks like.

What about a custody calendar app?

Parenting apps add a shared calendar to messaging, expenses and swap requests. That solves real planning problems, and it usually means both parents have accounts in the same app. Some also record when a request was sent or accepted, which is more than a plain calendar shows. Check what the app keeps, who can change it, and whether you can export it before relying on it as a record.

Our comparison of parenting apps looks at the main options. If a paper log is what you are weighing instead, see a notebook vs an app.

Calendar features vary by service and change over time. Check what yours records before relying on it. Documented prices are on its App Store and Google Play listings.

Which should you use for your custody schedule?

Usually both, for different jobs. Keep the custody schedule in a calendar, shared if that works for your family, so exchanges and events are not missed. Keep the record of what happened somewhere that only you write to, the same day, in plain facts.

If you only have the energy for one, the record is the one a calendar cannot replace. Our guide to a contemporaneous record of parenting time covers what a useful daily entry looks like, and custody schedule examples covers the planning side.

Documented keeps that daily record. A short entry about your own day, sealed when you save it and independently timestamped by an outside authority under RFC 3161, so the date on it does not rest on your word or ours. A calendar shows the plan. Documented shows what happened, and the record exports ready to hand to your attorney.

Frequently asked questions

Is a custody calendar the same as a custody record?

No. A custody calendar shows the schedule that was planned. A record shows what actually happened, written down close to the time.

Can I use Google Calendar for custody?

Yes, for the schedule. As a record it has limits: anyone with edit access can change or delete events, and it does not show an ordinary user a history of past versions.

Can a custody calendar be used as evidence?

It can be, but the judge decides. You may need to show who kept it and how, and a tally of many days is usually expected to be backed by the entries underneath. Ask your attorney.

Can the other parent change a shared calendar?

If they have edit access, yes. They can move or delete events, which is fine for planning but means the calendar cannot show what the schedule said before.

Should I keep a separate calendar for my record?

If you use a calendar as a record, yes. Keep the shared one for planning and your own for what happened, added to the same day.

Is a custody calendar app better than a shared calendar?

It can add messages, swap requests and expenses in one place, and some record when a request was made. Check what it keeps, who can change it, and whether you can export it.
