50/50 custody schedules — and what each one asks you to document

Written by the Documented team · Published August 3, 2026 · This is general information, not legal advice.

Key takeaways

A 50/50 custody schedule splits parenting time roughly evenly. The common 50/50 schedules — 2-2-3, 2-2-5-5, 3-4-4-3, and week on week off — reach the same split with very different numbers of exchanges.
The schedule you are on decides how much can go wrong. A 2-2-3 custody schedule hands the child over about 156 times a year; a week-on-week-off schedule does it about 52 times. Every exchange is a point where the schedule and the actual week can part company.
A custody schedule describes what is supposed to happen. It is not a record of what did. Nothing in the order counts the overnights you actually had.
Overnight counts can carry legal weight of their own. Illinois, as one example, applies a different child support calculation once each parent exercises 146 or more overnights a year — a threshold a 50/50 schedule can clear on paper and miss in practice.
What is worth writing down is the same in every custody schedule: the exchanges, the deviations from the schedule, and the ordinary days in between. What changes is how often.

What is a 50/50 custody schedule?

A 50/50 custody schedule is any parenting time schedule that divides the year roughly evenly between two parents — close to 182 overnights each. It is a description of the split, not the name of a specific schedule, which is why two parents can both say they have a 50/50 custody schedule and be living completely different weeks.

Courts rarely order “50/50” as such. What a court enters is a parenting plan with named days, times, and exchange points, plus holiday and vacation terms that override the regular schedule. The percentage is a summary of that plan, calculated after the fact. Your own order is the document that controls, and where this article and your order disagree, your order wins.

Whether a 50/50 split is available to you at all depends on your state’s law and on the best interests of your child as the court assesses them. That question is decided before the custody schedule is chosen. This article is about the part that comes after: living on the schedule, and keeping a record of how it actually went.

What do the common 50/50 custody schedules look like?

Four schedules cover most 50/50 custody arrangements. The difference between them is not the split — they all land near even — but the length of each block of time and the number of exchanges that produces.

Custody schedule	The rotation	Exchanges per year	Often used when
2-2-3	Two nights with parent A, two with B, three with A; reverses the following week	~156	Children are young and long gaps are hard
2-2-5-5	Two fixed nights each with A and B, then alternating five-night blocks	~104	Parents want fixed weekday anchors
3-4-4-3	Three nights with A, four with B; reverses the following week	~104	A predictable weekly schedule is preferred
Alternating weeks	Seven nights with each parent, often with a midweek visit	~52	Children are older, schools and homes are close

Two things about that table are worth noting before you pick a row.

The first is that the exchange count varies by a factor of three across four schedules that are all, on paper, 50/50. That is the single biggest practical difference between these custody schedules, and it is the one that matters most for record-keeping.

The second is that no schedule in the table survives contact with a calendar year untouched. Holidays, school breaks, summer, travel, illness, and work all cut across the rotation. Most parenting plans handle this by saying holiday and vacation terms supersede the regular custody schedule, which means the actual year almost never looks like the schedule you agreed to.

Overnight term

The unit most parenting time schedules are actually counted in — a night the child sleeps at that parent’s home. Percentages like 50/50 and 70/30 are usually overnight counts divided by 365, which is why an evening visit that ends at bedtime does not change the ratio. More terms in the glossary →

What about custody schedules that are not 50/50?

Most are not. Unequal schedules are ordinary, and each has its own documentation problem.

A 60/40 schedule — commonly a 4-3 rotation, or alternating weekends extended by one weeknight. About 219 overnights to 146.
A 70/30 schedule — often alternating weekends plus one or two weeknight overnights. About 256 to 109.
An 80/20 schedule — the traditional every-other-weekend custody schedule, sometimes with a midweek dinner visit. About 292 to 73.

The less time a custody schedule gives you, the more each block of it carries. A parent with 73 overnights has fewer chances to demonstrate an ordinary evening with their child, and a single cancelled weekend is a larger proportion of the year. If you are the parent with less time, the record of what you did with the time you had is doing more work than the same record would on a 50/50 custody schedule.

If you are the parent with more time, the useful record is different but no less real: the school runs, the appointments, the homework, the sick days. Day-to-day caregiving is easy to do and easy to forget, and it is exactly the kind of thing that is hard to reconstruct a year later.

Why does your custody schedule change what is worth documenting?

Because the number of exchanges is the number of opportunities for the plan and the week to diverge.

This is the practical point underneath all of the schedule labels. A 2-2-3 custody schedule is not “worse” than a week-on-week-off schedule, but it has three times the exchange surface. Every exchange is a specific time, a specific place, and two people who have to be there. A parent on a 2-2-3 schedule who records only the exchanges that go wrong has a log with no baseline. A parent on an alternating-weeks schedule who does the same has a log with almost nothing in it at all.

There is a second reason, and it is the one most parents do not see coming. The custody schedule in your order is a plan. It is not a record. Nobody, anywhere, is counting the nights your child actually spent at your house. The order says what should have happened; the calendar app says what was scheduled; neither is evidence of what did.

That gap can matter directly. In Illinois, the child support calculation changes once “each parent exercises 146 or more overnights per year with the child” — at that point the basic child support obligation is multiplied by 1.5 and apportioned by income (750 ILCS 5/505(a)(3.8)). Other states set their own thresholds, and some set none at all; the Illinois figure is a concrete example, not a statement of the law where you live. But the shape of the problem is general. A 50/50 custody schedule that promises 182 overnights and delivers 140 has crossed a line that exists in the statute, and the only way anyone knows which side of it you are on is if somebody counted.

So the answer to “what should I document” is not really schedule-specific. It is: the exchanges, the deviations from the schedule, and the ordinary days in between. What your custody schedule changes is how often you are doing it.

What should you record on an exchange day?

Six fields, written the same day. On a 2-2-3 custody schedule that is three short entries a week; on a week-on-week-off schedule it is one.

The date and the scheduled time. What the custody schedule called for.
The actual time. When your child was handed over, if it happened.
The place. The school, the curbside, the halfway point named in the order.
Who was there. Yourself, the other parent, whoever else the order permits.
What was exchanged. Backpack, medication, sports equipment, the coat that keeps not coming back.
Anything said about the next block of time. A request to swap a day, a heads-up about a late pickup.

Keep the uneventful ones. A run of ordinary exchange entries is what makes the one unusual entry believable, and a log that only contains problems reads as a log kept in order to find problems. That is a credibility question before it is a legal one, and it is covered in more depth in the guide on how often you should actually document. Where an exchange does not happen at all, documenting missed handoffs and late pickups covers what to write down.

How do you document a swap or a deviation from the custody schedule?

Deviations are the most common thing a custody schedule produces and the least commonly recorded. Somebody asks to move a weekend. A flight is delayed. A child is sick on a Sunday. None of that is misconduct, and most of it is two parents being reasonable — but a year of unrecorded reasonable adjustments is a year nobody can reconstruct.

Record four things for any change to the custody schedule:

What the custody schedule called for, and what happened instead.
Who asked, when, and through which channel.
What was agreed, in the words used — including whether makeup time was part of it.
Whether the makeup time actually happened, and on what date.

That last one is the one that gets dropped. Makeup time agreed in March and never taken is a fact that disappears entirely unless it was written down twice: once when it was agreed, once when it was or was not used.

Keep the agreements themselves where they were made. If a swap was arranged by text, save the thread rather than retyping it; the guide on text message and photo evidence covers how to keep those clean. Your log entry is your dated account of what happened; the message is the corroboration.

One more habit worth building at the same time: a running count of overnights, updated as the year goes. Not an estimate at the end. A running total is a small piece of arithmetic that turns into the answer to a question — how much parenting time did you actually exercise — that is otherwise very hard to answer honestly.

What should you leave out?

The other household, and your conclusions.

Do not document what happens on the other parent’s scheduled days. You were not there. A 50/50 custody schedule divides time precisely so that each parent is responsible for their own half, and an entry about a night you did not witness is hearsay in the everyday sense and a credibility problem in the legal one.
Do not question your child about the other household in order to fill in the gap, and do not build a log out of what they volunteer.
Do not characterize. “Exchange scheduled 6:00 PM, arrived 6:40 PM, no message” is usable. “Late again, as usual” is an argument, and an entry that argues invites an argument about the entry.
Do not track the other parent. Watching a house, following a car, or going through someone’s accounts is not documentation, and it can carry legal consequences of its own on top of what it does to your case.

Every one of those is the same rule stated four ways: document your own parenting time. That is the half of the custody schedule you can actually speak to.

What does your record have to survive to be used?

The usual three questions. Federal Rule of Evidence 901 asks whether the record is what you say it is, and Rules 902(13) and 902(14) allow certain electronic records to be self-authenticating with a proper certification. Rule 803(1) covers a statement made while or immediately after you perceived an event, and Rule 803(6) covers records kept as a regular practice — which is a fair description of a log kept on the rhythm of a custody schedule. Rule 1006 allows a summary of voluminous records, which is what an overnight count is. Rule 403 asks whether it is worth the court’s time. State numbering varies and admission is always the judge’s call; what actually holds up in family court goes through this in more detail.

Where does your own record fit?

A custody schedule is the one part of a custody case that repeats. Whatever schedule you are on, it will run 52 or 104 or 156 times this year, and each repetition is either recorded or gone. Nothing about that requires the other parent’s participation, an agreement, or a shared platform — it is your own account of your own days, which is the only part of this you fully control.

Documented is a private log built for exactly that. You write a short entry with the date and the facts, attach a photo if there is one, and every entry is sealed and independently timestamped the moment you save it — so an entry about a March exchange can be shown to have been written in March, rather than resting on your phone’s clock. Entries export in date order. It stays on your device, notifies no one, and involves no one else.

Frequently asked questions

What is a 2-2-3 custody schedule?

A 2-2-3 custody schedule gives one parent two nights, the other parent the next two, and the first parent the following three — then reverses, so the schedule repeats every two weeks and each parent gets alternating weekends. It splits time evenly and keeps both parents in frequent contact with the child, which is why this 50/50 schedule is often used with younger children. The tradeoff is roughly three exchanges a week, about 156 a year.

What is a 2-2-5-5 custody schedule?

A 2-2-5-5 custody schedule gives each parent the same two fixed weekdays every week — one parent always has Monday and Tuesday, the other always Wednesday and Thursday — and then alternates the remaining five-night blocks that include the weekend. It reaches a 50/50 split with about half the exchanges of a 2-2-3 schedule, and the fixed weekdays make it easier to plan around work and activities.

What does a 70/30 custody schedule look like?

A 70/30 custody schedule is typically alternating weekends plus one or two weeknight overnights, giving one parent roughly 256 overnights a year and the other roughly 109. Exact schedules vary widely, and the percentage is usually a description of the plan rather than a term written into it. What matters in most orders is the specific days and times the schedule names, not the ratio.

Can my work schedule affect custody?

It can affect which parenting time schedule is workable, which is a different thing from being held against you. Courts allocating parenting time consider the practical realities of both households, including work hours, travel, and who is available for school runs and appointments. A schedule that looks even on paper but that neither parent can actually staff tends not to survive the year, which is another reason a record of what actually happened is more useful than the plan alone.
