Data study Custody statistics 50/50 custody
A split-color custody calendar surrounded by charts showing how separated parents divide parenting time

42% of separated families in a 2026 study of 804 SplitDay households across more than 30 countries share parenting time 50/50; 23% use an 80/20 split, 13% use 70/30, 7% use 60/40, and 14% had not decided at the moment they started organising custody. Fathers who set up the family calendar choose equal time far more often than mothers (53% vs 38%), and 46% of families skip every named schedule template and build a custom weekly pattern instead.

Most published custody statistics come from court records or decade-old surveys. This study uses a different source: anonymized, aggregated setup choices from 804 families who created a custody calendar in SplitDay between 27 April and 5 July 2026. Every figure below carries its sample size, and the whole dataset is a free CSV download.

  • 50/50 is the most common custody split: 42% of separating parents set up an equal-time arrangement — yet a 57% majority still live with unequal or undecided splits.
  • Fathers choose equal time more often than mothers: fathers setting up the family calendar pick 50/50 in 53% of cases, mothers in 38%.
  • Mothers do the organizing: the parent who sets up the custody calendar is the mother in 68% of families, the father in 27%, and a grandparent or other caregiver in 5%.
  • No template fits half of families: 46% build a fully custom weekly pattern instead of any standard schedule.
  • Keeping track of the schedule is the #1 co-parenting pain point, reported by 77% of parents — nearly double the next concern, communication (40%).
  • Equal custody varies hugely by country: 58% choose 50/50 in Spain and 53% in Czechia, but only 26% in Germany, where 80/20 is the most common choice (36%).
  • 1 in 7 parents (14%) hasn't decided on a split at the moment they start organizing custody.

Methodology

Between April 27 and July 5, 2026, we analyzed anonymized, aggregated onboarding events from families setting up a custody calendar in SplitDay for the first time. Split percentages are based on the 804 users who made a final split selection (each user counted once, last choice kept). Schedule-pattern figures are based on 665 final pattern selections, parent-role figures on 754 completed setups, and pain-point figures on the 655 parents who reported at least one challenge. No personal data, names, calendars or messages were accessed — only event counts. Internal development and test devices were identified by device fingerprint and excluded before analysis. Percentages are rounded to the nearest whole number.

Sample:
n=804 families who made a final split selection. Sub-samples: 754 completed setups (parent role), 665 final schedule-pattern selections of which 357 were a named schedule, and 655 parents who reported at least one challenge.
Source:
Anonymized, aggregated first-party app data — onboarding event counts only. No personal data, names, calendars or messages were accessed.
Time window:
April 27 – July 5, 2026, across more than 30 countries.
Limitations:
First-party product data, not a probability sample; splits reflect what parents set up, which is not always identical to a court order; country samples of 30–149 families carry margins of several percentage points. Read the full limitations.

The split parents choose

Asked how parenting time will be divided, parents setting up a calendar in 2026 chose:

Parenting-time splitShare of familiesUsers (n=804)
50/50 — equal time42%338
80/20 — primary home + weekends23%187
Undecided at setup14%113
70/3013%108
60/407%58

Two numbers stand out. First, while 50/50 custody is the single most common choice, most separated families still don't split time equally. Second, 14% of parents open a custody calendar before they have agreed on a split at all — for many families, the calendar is where that negotiation happens, not where it ends.

Fathers pick 50/50 more often than mothers

The parent doing the setup matters. Fathers who organize the family's custody calendar choose an equal split 53% of the time. Mothers choose 50/50 in 38% of setups, and are far more likely to select 80/20 (27% of mothers vs 17% of fathers).

Setup parentChooses 50/50Chooses 80/20Sample
Father53%17%n=214
Mother38%27%n=530
Other caregiver41%15%n=59

This gap is consistent with what family-time researchers have long observed: equal-time arrangements are disproportionately sought by fathers, while primary-residence arrangements remain more common when mothers organize the schedule. Our data can't say who proposed the split — only who entered it — but the 15-point difference is one of the largest in the dataset.

Where 50/50 custody is normal — and where it isn't

Among the six countries with at least 30 setups in the study window, equal custody ranges from a clear majority of families to barely a quarter:

CountryChoose 50/50Most common splitSample
Spain58%50/50n=50
Czechia53%50/50n=77
France46%50/50n=93
United States42%50/50n=134
Brazil32%80/20 (36%)n=99
Germany26%80/20 (36%)n=149

The German result is striking: despite years of public debate about the Wechselmodell (alternating residence), German families in our data set up an 80/20 arrangement more often than any other split. Spain shows the opposite pattern — consistent with custodia compartida becoming the default expectation in much of the country. As always, what families set up in an app reflects lived arrangements, which can differ from what courts formally order. Court records and EU-wide surveys put the numbers on a different footing again, which is why we compare all three measures in our breakdown of which countries choose 50/50 most.

The schedules behind the splits

A split is a number; a schedule is who wakes up where on Tuesday. Here, the clearest finding is that no standard schedule fits half of families — 46% skip every named template and paint a custom week instead. Among the 357 families who did choose a named schedule:

Schedule familyShare of named schedules
Weekend-based (every other weekend, 1st/3rd/5th, every weekend)36%
Alternating weeks23%
Split week (fixed weekday homes)18%
2-2-3 rotation13%
2-2-5-5 rotation5%
All others (4-3, 3-4-4-3, extended weekend, every third day…)6%

If you're choosing between these, our custody schedule maker guide walks through the trade-offs by age and distance.

What co-parents say is hardest

During setup, parents can name the challenges they're dealing with. Of the 655 parents who selected at least one:

  • Keeping track of the schedule — 77%
  • Communication with the other parent — 40%
  • Keeping records and documentation — 32%
  • Money and shared expenses — 28%
  • Handoffs and transitions — 23%
  • Making decisions together — 15%
  • Kids confused about where they'll be — 10%

The schedule itself outranks conflict, money and paperwork combined with room to spare — which matches why most families arrive at a shared calendar in the first place.

Fresh usage insights (updated August 2026)

The figures above are the published study, collected 27 April – 5 July 2026 (n=804). Below is a refresh of the same measures run on a longer window, 27 April – 23 August 2026, using the identical method — one family counted once, final choice kept. Where a figure has been refreshed we show both values and both sample sizes rather than silently replacing the original. The headline equal-time figure remains 42% (n=804): it is not refreshed here, because the longer window shows a movement we have not yet been able to explain, and we would rather publish the confirmed number than the newer one.

Equal time is mostly a national variable

Across the longer window, the country a separated parent lives in predicts equal-time custody more strongly than anything else measured: 63% of families setting up a calendar in Spain choose 50/50, against 31% in Germany and 29% in Brazil — a 34-point spread across countries measured the same way. The rank order is identical to the published study on a sample 1.5–2× larger. Germany and Brazil sit within two points of each other and should be read as tied-lowest rather than ranked. These differences reflect national legal defaults and cultural norms around shared residence, not differing commitment among parents — and, as everywhere in this study, they record what parents set up, which is not always identical to a court order.

CountryChoose 50/50 (Apr–Aug 2026)SamplePublished study (Apr–Jul 2026)
Israel65.9%n=44
Spain63.2%n=9558% (n=50)
Canada62.1%n=58
Czechia61.7%n=12053% (n=77)
France54.8%n=19746% (n=93)
Poland52.0%n=50
Italy50.0%n=32
United States44.6%n=20442% (n=134)
Germany31.0%n=19726% (n=149)
Brazil28.9%n=19032% (n=99)

Countries with fewer than 30 selections in the window are suppressed entirely. Individual percentages are directional; the ordering and the size of the spread are the solid findings.

Europe builds week-on/week-off; North America builds rotations

The same national pattern shows up in the shape of the schedule, not just the size of the split. Alternating weeks is chosen by 30.7% of Spanish and 26.7% of French families setting up a schedule between April and August 2026, against 10.9% in the United States — where the 2-2-3 rotation is roughly three times as popular as it is in France, Germany or Brazil (12.4% of US families, against 4.3–4.8%). Brazil is the weekend-based outlier at 33.3%, which is consistent with its 80/20-leaning split profile in the table above. Country samples here run from 34 to 193 families.

Refreshed figures: custom schedules and co-parenting challenges

Two of the published measures have been re-run on the longer window. Both hold, with small downward drift consistent with a broader, less self-selected sample rather than any real change.

  • No template fits most families. 43.4% of parents built a fully custom weekly pattern rather than choosing any named schedule (n=1,158 pattern selections, April–August 2026), against the published 46% (n=665, April–July 2026). That is more than twice the share picking the most popular named template.
  • Keeping track of the schedule is still the hardest part, by a factor of two. 74.7% of separated parents name it, against 35.6% for communication with the other parent (n=1,425 parents, April–August 2026) — against the published 77% and 40% (n=655). The rank order of all seven challenges is identical across both windows: schedule 74.7%, communication 35.6%, records and documentation 29.4%, money and shared expenses 25.7%, handoffs and transitions 18.5%, making decisions together 12.9%, and kids being confused about where they will be 9.3%.

How we know this. These figures come from anonymized, aggregated usage analytics from parents who set up a co-parenting calendar in the SplitDay app and who consented to analytics collection. We count each family once and keep their final choice. We never access, read or analyze names, messages, calendar contents, documents, photos or any free-text a parent enters — only counts of anonymous, pre-defined events such as “a schedule pattern was selected”. Any group smaller than 30 families is suppressed and never reported. Figures cover 27 April 2026 to 23 August 2026 across more than 30 countries; country-level figures are reported only where at least 30 families are represented, and samples of 30–200 families carry margins of several percentage points. This is first-party product data, not a probability sample of all separated parents: it reflects what parents set up in an app, which is not always identical to a court order, and the mix of countries in the sample changes over time, so global averages should be read alongside the per-country figures rather than on their own.

Limitations

This is first-party product data, not a probability sample. Families who download a co-parenting app are, by definition, organizing custody actively, and may differ from the general population of separated parents. Splits reflect what parents set up, which is not always identical to a court order. Country samples run from 30 to 149 families in the published study and from 30 to 204 in the refresh window; both carry margins of several percentage points. We publish the sample size next to every figure so you can weigh them yourself.

Frequently asked questions

What is the most common custody split?

A 50/50 split is the single most common arrangement: 42% of separating parents chose equal time when setting up a custody calendar in SplitDay between April and July 2026 (n=804). An 80/20 arrangement — roughly every-other-weekend — was second at 23%.

Do fathers or mothers choose 50/50 custody more often?

Fathers. When the father is the parent setting up the family custody calendar, he chooses a 50/50 split 53% of the time; mothers choose 50/50 38% of the time (SplitDay data, April–July 2026).

Which countries have the most 50/50 custody?

In SplitDay setup data (April–July 2026), equal 50/50 splits were most common in Spain (58%) and Czechia (53%), and least common in Germany (26%), where 80/20 was the most frequent choice at 36%.

What is the most common custody schedule pattern?

No standard pattern fits most families: 46% build a fully custom weekly schedule. Among named schedules, weekend-based patterns lead (36%), followed by alternating weeks (23%), split-week (18%) and the 2-2-3 rotation (13%).
