In Re Brazil

DICKENSON, Justice.

This is a child custody case in which the child’s father filed a motion to modify under Tex.Fam.Code Ann. § 14.08 (Vernon Supp.1980). The original decree named the mother, Kathryn G. Brazil Graham, as managing conservator of the child, Michael James Brazil, who is now 10 years old. The father, Richard Ray Brazil, was named Pos-sessory Conservator with rights of visitation. The father’s motion alleges that the mother is permitting the child to live with his maternal grandmother, Gladys Morris, and it asks that the father be appointed as managing conservator of the child.
