In Texas, courts use “conservatorship” language rather than “custody,” In Texas, the term is Joint Managing Conservatorship (commonly called “joint custody.”)
Joint Managing Conservatorship (JMC) means that both parents share the rights and duties of raising the child/children, though not necessarily equal time. Generally, there is a JMC with the right to designate primary residence of the child, and that is where the child will primarily reside.
The non-primary conservator will have a visitation schedule that is in the best interest of the child.
