Texas Custody Overnights FAQ

Does 50/50 custody automatically eliminate child support in Texas?

No. Texas Family Code has NO statutory formula for 50/50 custody. Child support is presumptively set on the paying parent's net resources. However, in 50/50 arrangements, Texas family courts commonly agree to an "offset method" where the higher earner pays the difference.

How many overnights are in the Texas Standard Possession Order (SPO)?

Standard SPO yields approx. 105 overnights per year. The Expanded SPO (pickup Thursday after school to Monday morning) yields approx. 140–145 overnights per year.
