Mississippi's House Bill 1662 makes equal 50-50 joint physical custody the legal starting point in every contested divorce custody case filed on or after July 1, 2026, requiring chancery judges to document written findings before deviating. Mississippi becomes the sixth state with an equal-parenting presumption, per Mississippi Today.
| Key Fact | Detail |
|---|---|
| What happened | Mississippi enacted HB 1662, a rebuttable presumption of joint custody with equal (50-50) parenting time |
| When effective | July 1, 2026 — applies only to cases and modifications filed on or after that date |
| Where | Mississippi chancery courts (all 82 counties) |
| Who's affected | Divorcing and separating parents with minor children; not retroactive to existing orders |
| Key statute affected | Miss. Code Ann. § 93-5-24 (custody determinations) |
| Practical impact | Judges must start at 50-50 and put written reasons in the record to order anything else |
Why this matters legally
HB 1662 shifts the legal default in Mississippi custody disputes from a judge-driven "best interest" analysis with no starting presumption to a structured framework that begins at equal time. Under the new law, a chancery judge must presume that awarding both parents joint physical custody with roughly equal parenting time serves the child's best interest. To order anything else, the judge must make specific written findings explaining why equal time would not work.
This is a rebuttable presumption, not a guarantee. A parent who opposes 50-50 can still win a different arrangement by presenting evidence — but the burden has moved. Before HB 1662, the parent seeking primary custody often did not have to overcome a formal starting point. Now the parent seeking less than equal time must affirmatively show why the presumption should not apply.
How Mississippi law handles this
Mississippi custody decisions are governed by Miss. Code Ann. § 93-5-24, which authorizes joint legal and joint physical custody, and by the long-standing Albright factors — a 12-factor best-interest test Mississippi courts have applied since the 1983 Mississippi Supreme Court decision in Albright v. Albright. HB 1662 layers an equal-time presumption on top of this existing framework rather than replacing it.
Notably, the final bill dropped earlier proposed changes to Mississippi's child-support guidelines under Miss. Code Ann. § 43-19-101, which set percentage-of-income support obligations (14% of adjusted gross income for one child, scaling to 26% for five or more). That means support is still calculated under the existing statutory percentages, even though parenting time may now skew closer to equal. Parents should not assume a 50-50 schedule automatically eliminates a child-support obligation.
The presumption applies prospectively. Cases and modification petitions filed before July 1, 2026 continue under prior law, and existing custody orders are not automatically reopened. A parent who wants the new presumption to apply to an old order must file a modification and meet Mississippi's separate standard requiring a material change in circumstances that adversely affects the child.
Practical takeaways
-
Check your filing date. The presumption applies only to custody cases and modifications filed on or after July 1, 2026. If your case is already pending, prior Mississippi law and the Albright factors govern unless you file a qualifying modification.
-
Document your parenting involvement now. Because the new default is equal time, a parent seeking primary custody must build a record — school records, medical appointments, daily caregiving — showing why 50-50 would not serve the child.
-
Survivors of abuse should gather evidence early. Critics of HB 1662, cited in Mississippi Today, warned the presumption could endanger domestic-violence survivors. Mississippi judges retain authority to rebut the presumption with written findings, so protective orders, police reports, and DV documentation matter more than ever.
-
Do not assume support disappears. Child support remains calculated under Miss. Code Ann. § 43-19-101 percentages. A 50-50 schedule may affect a support calculation but does not automatically zero it out.
-
Parents of infants and very young children should prepare specific arguments. The bill drew criticism over equal time for infants. Age-appropriate scheduling concerns are exactly the kind of evidence a judge can use to rebut the presumption.
