Mississippi Governor Has Two Days to Sign Historic 50-50 Joint Custody Bill
Governor Tate Reeves must decide by April 13, 2026 whether to sign House Bill 1662, which would make Mississippi the sixth state in the nation to establish a rebuttable presumption of equal parenting time in custody disputes. The bill passed the House unanimously 118-0 and includes updated child support calculations for equal custody arrangements. If signed, the law takes effect July 1, 2026, fundamentally changing how Mississippi courts approach custody determinations.

What HB 1662 Actually Changes in Mississippi Custody Law
HB 1662 establishes a rebuttable presumption that equal parenting time serves the best interests of children in Mississippi custody cases. Under current Mississippi law, judges have broad discretion in determining custody arrangements with no starting assumption. The new law would require courts to begin with equal custody as the baseline, shifting the burden to the parent opposing equal time to demonstrate why another arrangement better serves the child.
The bill modifies Miss. Code Ann. § 93-5-24, which currently governs custody determinations based on the Albright factors established in Albright v. Albright (1983). Those twelve factors remain relevant, but HB 1662 adds a statutory presumption that courts must apply before weighing discretionary factors. This represents the most significant change to Mississippi custody law in over four decades.
The legislation also updates child support calculations under Miss. Code Ann. § 43-19-101 to account for equal parenting time arrangements. Current guidelines were designed primarily for traditional custody arrangements where one parent has primary physical custody. The updated calculations recognize that parents sharing equal time both incur direct costs for housing, food, and daily care.
Why This Matters for Mississippi Parents
Mississippi courts currently award mothers primary custody in approximately 68% of contested cases, according to 2024 data from the Mississippi Administrative Office of Courts. HB 1662 would not eliminate judicial discretion but would change the starting point for custody negotiations and litigation. Parents seeking primary custody would need to present evidence that equal time would harm the child rather than simply arguing they should be the primary caregiver.
The five states that have already enacted similar presumptions show measurable impacts on custody outcomes. Kentucky, which passed its law in 2018, saw equal custody arrangements increase from 31% to 52% of custody orders within three years, according to a 2022 University of Kentucky study. Arizona (2013), Arkansas (2021), West Virginia (2022), and Florida (2023) have reported similar shifts toward more equal parenting time arrangements.
For Mississippi families, this change affects both initial custody determinations and modifications of existing orders. Parents with current custody arrangements would not see automatic changes, but parents seeking modifications after July 1, 2026 would have the new presumption apply to their cases.
How the Rebuttable Presumption Works
A rebuttable presumption means courts assume equal parenting time is appropriate unless a parent presents evidence to overcome that assumption. Under HB 1662, evidence that could rebut the presumption includes:
- Documented history of domestic violence or abuse
- Substance abuse issues affecting parenting capacity
- Geographic distance making equal time impractical (more than 50 miles between parents)
- Work schedules that prevent meaningful parenting during allocated time
- Child's established school and community connections requiring primary residence
- Evidence that equal time would disrupt the child's emotional or educational stability
The standard of proof for rebutting the presumption is preponderance of the evidence, meaning the opposing parent must show it is more likely than not that equal time is not in the child's best interests. This is a lower standard than clear and convincing evidence used in some other family law contexts.
Child Support Calculations Under Equal Custody
HB 1662 addresses a practical concern that has complicated equal custody arrangements in Mississippi: how to calculate child support when both parents share time equally. The bill adopts an income shares model with adjustments for equal parenting time.
Under current Miss. Code Ann. § 43-19-101, child support guidelines assume one parent has primary custody and the other pays support based on a percentage of income. For equal custody arrangements, the bill requires courts to calculate each parent's proportional income and adjust support so the higher-earning parent contributes to balancing household resources available to the child in both homes.
For example, if Parent A earns $80,000 annually and Parent B earns $40,000, and they share 50-50 custody, the higher-earning parent would pay a reduced support amount to equalize the child's standard of living in both households. The specific formula considers combined parental income, number of children, and each parent's percentage of overnights.
Practical Takeaways for Mississippi Parents
-
Monitor the governor's decision by April 13, 2026, as it determines whether the law takes effect July 1, 2026 or faces veto.
-
Pending custody cases filed before July 1, 2026 will proceed under current law, but cases filed after the effective date will apply the new presumption.
-
Parents considering filing for custody or modification may want to evaluate timing based on whether HB 1662 is signed and how the presumption affects their specific circumstances.
-
Existing custody orders remain in effect, but modification petitions filed after July 1, 2026 would apply the new presumption.
-
Document any factors that would support or rebut the equal custody presumption, as evidence becomes more important when courts start from an equal time baseline.
-
Consult with a Mississippi family law attorney to understand how the potential law change affects your specific situation.
Frequently Asked Questions
Does HB 1662 guarantee 50-50 custody in Mississippi?
No, HB 1662 creates a rebuttable presumption, not a guarantee. Courts start with the assumption that equal parenting time is appropriate, but either parent can present evidence to overcome that presumption. Judges retain discretion to order different arrangements when evidence shows equal time would not serve the child's best interests. The presumption changes the starting point, not the final outcome.
When would the new custody presumption take effect?
If Governor Reeves signs HB 1662 by April 13, 2026, the law takes effect July 1, 2026. Cases filed on or after that date would apply the new equal custody presumption. Cases already pending before July 1, 2026 would proceed under current Mississippi custody law without the presumption.
Will my existing custody order automatically change to 50-50?
No, existing custody orders remain in effect regardless of whether HB 1662 becomes law. The new presumption applies only to new custody determinations and modification petitions filed after the effective date. Parents with current orders who want to seek modification would need to file a petition and demonstrate a material change in circumstances, with the new presumption then applying to the modification analysis.
How does HB 1662 affect child support payments?
HB 1662 includes updated child support calculations for equal custody arrangements under Miss. Code Ann. § 43-19-101. When parents share 50-50 custody, the higher-earning parent typically pays reduced support to help equalize the child's standard of living in both homes. The exact amount depends on the income differential between parents and the number of children.
What evidence can overcome the equal custody presumption?
Parents can rebut the presumption by showing domestic violence history, substance abuse affecting parenting, geographic distance over 50 miles, incompatible work schedules, established school connections, or evidence that equal time would harm the child's stability. The opposing parent must prove by preponderance of evidence that equal custody is not in the child's best interests.
