The 4-3 (Every Weekend Split) Custody Schedule
Four weekdays with one parent, Friday-to-Sunday with the other — the same split every single week.
How the 4-3 (Every Weekend Split) schedule works
Parent A has Monday–Thursday, Parent B has Friday–Sunday, every week. There's no alternation at all, which makes it the most predictable unequal split — but one parent always has the school nights and the other always has the weekends.
| Mon | Tue | Wed | Thu | Fri | Sat | Sun | |
|---|---|---|---|---|---|---|---|
| Week 1 | A | A | A | A | B | B | B |
| Week 2 | A | A | A | A | B | B | B |
Across the two-week cycle that's 8 overnights with Parent A and 6 with Parent B — a ~60/40 time split.
Advantages
- Identical every week — nothing to track
- Only two handoffs a week
- Close to equal time (57/43)
Trade-offs
- One parent gets all the weekend fun, the other all the homework — roles can calcify
- No alternation means neither parent ever experiences the other side
Who it suits
The 4-3 (Every Weekend Split) schedule tends to fit co-parents whose work schedules genuinely map to weekday/weekend roles, with deliberate holiday trades to balance the fun.

What this schedule means for shared expenses
Time split and money split are separate decisions: a ~60/40 schedule doesn't automatically make every cost match the time split. Clothing, activities, and school costs follow whatever your order or agreement says — and with kids moving between homes, receipts and reimbursements multiply. A shared, neutral ledger where each expense carries its receipt and agreed split keeps the schedule about the kids, not the money.
