Usually, the managing conservator (custodial parent) is given the right to decide where the child will live. Sometimes, the court limits this right by restricting the location of a child’s primary home to a certain geographic area, often a specific county and the counties that border it. This is called a geographic restriction. It is put into an order so that both parents can be involved in a child’s daily life.
When parents have “joint custody” because both have been named joint managing conservators, Texas law still prefers a court order that gives one parent the exclusive right to decide where the child will primarily live.
