One parent (or even a non-parent) can be named Sole Managing Conservator if there is a good reason to do so. The Sole Managing Conservator has the exclusive right to make most decisions about the child.

There are a number of reasons a judge might name a parent (or nonparent) Sole Managing Conservator, which include:

- absence of the other parent in the child’s life

- family violence by the other parent

- child abuse or neglect by the other parent

- alcohol or drug abuse by the other parent
