HB 1662 Mississippi House · 2026 Regular Session

Joint custody matters; create rebuttable presumption in favor of.

HB 1662 creates a rebuttable presumption in Mississippi that joint custody with equal parenting time is in a child's best interest for all custody cases. It requires courts to justify deviations from this presumption with strong evidence and document their reasons, unless both parents agree to a deviation. The bill also standardizes child support calculations for joint custody cases and defines key terms like "joint physical custody" (significant time with each parent) and "joint legal custody" (shared decision-making). This applies to every custody determination in Mississippi, including cases involving family violence history, where specific rebuttal standards apply.

MODERATE
This bill updates Mississippi's custody laws to establish a rebuttable presumption that joint custody is in a child's best interest, effective July 1, 2026. It clarifies specific circumstances under which this presumption can be overturned, such as when parents agree on all issues or if a parent is a registered sex offender. The changes also refine the definition of joint physical custody to explicitly link it to the new joint custody rules.
Scope change
The bill's scope is expanded to create a new legal presumption favoring joint custody for initial orders entered on or after July 1, 2026, while explicitly excluding modifications to existing orders from this new presumption.
REQUIREMENT

Added a rebuttable presumption that joint custody is in the child's best interest, which can only be overturned if parents agree on all issues, if the other parent has issues like substance abuse, if evidence supports it, if one parent is a registered sex offender, or other relevant factors.

TIMELINE

Established a new effective date of July 1, 2026, for the joint custody presumption to apply to initial temporary and final orders, while explicitly stating it does not apply to modifying existing orders.

DEFINITION

Modified the definition of 'joint physical custody' to require that parenting time be awarded as set forth in the new joint custody subsection.

ELIGIBILITY

Added specific eligibility criteria for rebutting the joint custody presumption, including situations where one parent is a registered sex offender or in the custody of the Department of Corrections.
