Answer:  The term “primary custody” does not appear in the Texas Family Code.  However, one parent is typically given the exclusive right to designate the children’s primary residence, and that residence can be restricted to a particular geographic area (such as Denton County and contiguous counties).  That parent usually also has the right to receive child support from the other parent.   Having these rights is the practical equivalent of having “primary custody” of your children.
