Mississippi's HB 1662 took effect July 1, 2026, creating a rebuttable presumption that equal (50-50) joint physical and legal custody serves a child's best interest. Signed by Gov. Tate Reeves, the law requires chancery judges to start every custody case at a 50-50 split and document in writing any reason for deviating, while preserving the domestic-violence exception under Miss. Code § 93-5-24(9).

Why This Matters Legally
HB 1662 reverses the default starting point for custody disputes in Mississippi. Before July 1, 2026, chancery judges weighed the twelve-factor Albright analysis from a neutral baseline, with no thumb on the scale toward any particular custody arrangement. Now, judges must presume that equal joint physical and legal custody serves the child's best interest, and the parent seeking a different arrangement carries the burden of rebutting that presumption with evidence.
This is a rebuttable presumption, not a mandate. A parent can still overcome it by showing that a 50-50 split would not serve the child — for example, by demonstrating a history of family violence, substance abuse, or a work schedule incompatible with equal time. But the change matters because it shifts the burden of proof. As reported by Mississippi Today, the legislation aligns Mississippi with a national trend toward shared-parenting presumptions that has taken hold in states like Kentucky and Arkansas.
How Mississippi Law Handles This
Mississippi custody law now operates under Miss. Code § 93-5-24 with the new equal-custody presumption layered on top of the existing best-interest framework. Chancery judges retain full discretion to deviate from 50-50, but HB 1662 imposes a documentation requirement: any judge ordering an unequal split must state the specific reasons in writing. This written-findings rule creates a clearer appellate record and makes deviations easier to review.
The domestic-violence safeguard remains intact. Under Miss. Code § 93-5-24(9), a documented history of family violence still triggers a separate analysis, and the equal-custody presumption does not apply where credible evidence of abuse exists. This preserves the protective framework that predates HB 1662, ensuring the shared-parenting default never overrides child-safety concerns. Parents navigating these issues should understand how custody evaluations and protective findings interact with the new presumption.
HB 1662 also shifts Mississippi child support toward an income-shares model, which calculates support based on the combined income of both parents rather than a flat percentage of the non-custodial parent's income alone. Mississippi has historically used a percentage-of-income guideline — 14% of adjusted gross income for one child, rising to 20% for two and 22% for three under Miss. Code § 43-19-101. As parenting time equalizes toward 50-50, the income-shares approach better reflects that both households now share direct costs.

Practical Takeaways
-
Assume 50-50 is the starting point. If you are divorcing in Mississippi after July 1, 2026, expect the chancery court to begin from an equal custody baseline. Build your case around that reality rather than the old neutral standard.
-
Document your parenting involvement now. Because the presumption is rebuttable, evidence matters. Keep records of school pickups, medical appointments, extracurricular activities, and daily caregiving. A detailed parenting plan strengthens your position whether you seek equal time or a deviation.
-
Understand what rebuts the presumption. Family violence, substance abuse, an unstable home, or a work schedule that makes equal time impractical can overcome the 50-50 default. If safety is a concern, the Miss. Code § 93-5-24(9) domestic-violence exception applies and should be raised early with supporting documentation.
-
Recalculate child support expectations. The move toward an income-shares model means support figures may differ from prior percentage-based estimates. Gather income documentation for both parents and revisit your numbers.
-
Get familiar with the deviation record. If a judge orders anything other than 50-50, that decision must now be explained in writing. Review those findings carefully — they form the basis for any appeal and clarify exactly what the court weighed.
