Understanding 60/40 Custody

A 60/40 custody schedule is a near-equal arrangement where one parent has the child approximately 60% of the time (about 219 overnights per year) and the other parent has 40% (about 146 overnights). This split is increasingly popular because it provides a meaningful amount of time with both parents while still designating a primary residential parent for school enrollment and stability purposes.

The 60/40 arrangement sits in a sweet spot for many families. It provides enough structure that the child has a clear primary home, which can simplify school logistics, medical appointments, and social connections. At the same time, the non-primary parent has substantial time -- nearly three full days per week -- to maintain a deep, involved relationship with the child.

Popular 60/40 Schedule Formats

4-3 Schedule: The child spends 4 days with one parent and 3 days with the other, every week. The days are fixed (for example, Monday through Thursday with Parent A, Friday through Sunday with Parent B), providing maximum predictability. This schedule results in a 57/43 split, which rounds to 60/40.

Alternating Weekends + Midweek Overnights: The primary parent has most of the week, the other parent gets alternating weekends (Friday to Sunday) plus two set weekday overnights each week. This gives the second parent 4 overnights in alternate weeks and 2 in the other weeks.

Modified 3-4-4-3: Over a two-week cycle, one parent gets 3-day and 4-day blocks that total slightly more time than the other parent. This creates a natural rhythm while keeping maximum separation from either parent to just 4 days.

When 60/40 Works Best

A 60/40 schedule works particularly well when both parents live in the same school district, both want significant involvement but one has slightly less availability during the week, the family is transitioning from a more unequal arrangement toward 50/50, or one parent travels occasionally for work but is very involved when home.

Frequently Asked Questions

Is 60/40 considered shared custody?

Yes, in virtually all states, a 60/40 arrangement qualifies as shared or joint physical custody. This designation affects child support calculations and often triggers a shared custody adjustment that reduces the support obligation compared to sole custody arrangements.

Can a 60/40 schedule change to 50/50 over time?

Yes, many families start with 60/40 and gradually move toward 50/50 as circumstances change. Common triggers include the child getting older and adapting better to transitions, a parent's work schedule becoming more flexible, or both parents moving closer together. Either parent can file for a modification if there has been a substantial change in circumstances.

How does 60/40 compare to 70/30?

The difference between 60/40 and 70/30 is roughly one additional overnight per week with the non-primary parent. This extra night can be significant -- it means the non-primary parent has the child during some weekday routines (homework, dinner, bedtime), which strengthens the day-to-day relationship. The 60/40 split also typically results in a larger child support reduction than 70/30.
