Joint Managing Conservatorship (JMC)

Written and reviewed by Shane M. Boasberg, founder of SMB Law, PC · Licensed in Texas since 2003 · Updated October 2026

Definition: Joint managing conservatorship is the Texas arrangement, presumed in a child’s best interest under Family Code § 153.131, in which both parents share decision-making rights for the child while the order specifies which parent designates the child’s primary residence.

Also called: JMC, joint custody, joint managing conservators

What joint managing conservatorship means in Texas

Joint managing conservatorship, or JMC, is the default form of conservatorship in Texas. Family Code § 153.131(b) creates a rebuttable presumption that appointing the parents as joint managing conservators is in the best interest of the child. The presumption is overcome only by evidence that joint appointment would significantly impair the child’s physical health or emotional development, or by a finding of family violence under § 153.004.

JMC means the parents share the rights and duties of a managing conservator. It does not mean they share them equally on every issue, and it does not mean equal time. Section 153.135 says so in plain words: joint managing conservatorship does not require equal or nearly equal periods of physical possession.

How it works in practice

When the court orders JMC, § 153.134(b) requires the order to do several things. It must designate which conservator has the exclusive right to designate the primary residence of the child, and either set a geographic area for that residence or state that there is no restriction. It must specify the rights and duties each parent holds exclusively, independently, or jointly. And it must include provisions to reduce the need for future court action.

Most JMC orders divide the big three rights, primary residence, education, and non-emergency invasive medical decisions, in some combination. One parent typically holds the residence right. The others may be joint or exclusive to one parent after consultation. The possession schedule is usually a standard possession order or an agreed variation.

Why it matters in your case

Because JMC is the starting point, a parent who wants sole decision-making authority has to prove why the presumption should not apply. For most parents the practical question is not whether JMC will be ordered, but how the exclusive rights and the geographic restriction will be written. Those two provisions control where the child lives and goes to school, and they are the hardest to change later.

Example

Hannah and Diego separate when their son is six. The Travis County court names them joint managing conservators. Hannah holds the exclusive right to designate the primary residence within Travis County and contiguous counties. Education decisions are joint. Non-emergency medical decisions are Hannah’s after consulting Diego. Diego has an expanded standard possession order.
