Understanding 70/30 Custody Schedules

A 70/30 custody schedule gives one parent approximately 70% of the parenting time (about 256 overnights per year) and the other parent approximately 30% (about 109 overnights). This arrangement is one of the most common custody splits in the United States, particularly when one parent serves as the primary caregiver and the other has regular, meaningful parenting time.

The 70/30 split offers a balance between providing stability through a primary home and ensuring the child maintains a strong relationship with both parents. It is well-suited for situations where one parent has a demanding work schedule, parents live somewhat apart (but not long-distance), or the child benefits from having one primary home base during the school week.

Popular 70/30 Schedule Formats

5-2 Schedule: The child spends 5 weekdays with the primary parent and every weekend (Friday evening to Sunday evening) with the other parent. This provides consistency during the school week and gives the non-primary parent dedicated quality time on weekends. The challenge is that the primary parent may feel they only have the child during "work" days while the other parent gets the fun weekends.

Every Other Extended Weekend: The child spends every other weekend from Thursday after school to Monday morning with the non-primary parent. This provides a 4-night block that allows for more meaningful time, including weekday evening routines, while reducing the frequency of transitions.

4-3 Schedule: While technically closer to 60/40, a modified 4-3 schedule can achieve a 70/30 split when combined with holiday and summer adjustments. The child spends 4 days with the primary parent and 3 with the other each week, with the specific days remaining consistent for predictability.

How 70/30 Affects Child Support

In most states, a 70/30 custody split results in the non-custodial parent paying child support. The amount is typically calculated based on both parents' incomes and the 30% time-sharing credit. Some states begin reducing support obligations when the non-custodial parent has more than 25-35% of overnights.

Frequently Asked Questions

Is 70/30 better than 50/50 for young children?

Many child development experts suggest that young children (under 3-4) benefit from having a primary home base with frequent visits to the other parent, which often results in a 70/30 or similar arrangement. As children grow, many families gradually transition toward a more equal split. However, every family is different, and the best arrangement depends on the specific circumstances, including each parent's availability and the child's temperament.

Can a 70/30 schedule include midweek visits?

Yes, many 70/30 schedules include a midweek dinner visit or overnight for the non-primary parent. For example, the child might spend Wednesday evenings with the non-primary parent, returning after dinner or the next morning. This reduces the maximum time between contacts from a week to 3-4 days, which is particularly beneficial for younger children.

How do holidays work with a 70/30 schedule?

Holidays typically override the regular schedule regardless of the custody split. Most 70/30 orders alternate major holidays (Thanksgiving, Christmas, spring break) between parents each year. The non-primary parent often receives additional holiday time to partially offset the unequal school-year schedule. Summer may also include extended blocks with the non-primary parent.
