Mississippi HB 1662: 50-50 Custody Presumption Heads to Conference

Mississippi HB 1662 would make equal 50-50 parenting time the default in all custody cases. Bill heads to conference committee before July 1, 2026 effective date.

By Antonio G. Jimenez, Esq.Mississippi8 min read

Mississippi is on the verge of becoming the sixth state in the nation to make equal 50-50 parenting time the legal default in all divorce and custody cases. House Bill 1662, which passed both chambers in different forms, now sits in a conference committee that must reconcile the House and Senate versions before the 2026 legislative session ends. If signed into law, the new standard takes effect July 1, 2026, and would fundamentally reshape how Mississippi courts award custody.

Why This Matters Legally

HB 1662 replaces Mississippi's current "best interest of the child" discretionary framework with a structured presumption that both parents start with equal time. Under the current standard established in Miss. Code Ann. § 93-5-24 and the landmark Albright v. Albright factors (adopted by the Mississippi Supreme Court in 1983), judges weigh 12 subjective factors — moral character, emotional ties, stability of the home, and others — with no built-in preference for either parent. In practice, as Mississippi Today reported, that discretion has resulted in one parent (often the mother) receiving primary physical custody in roughly 80% of contested cases statewide.

The bill flips that default. Under HB 1662, a court must begin every custody determination with a presumption of approximately equal parenting time — meaning roughly 182.5 overnights per year for each parent. A parent seeking more time would bear the burden of proving by a preponderance of the evidence that deviation from equal time serves the child's best interest. That is a significant procedural shift: instead of two parents arguing for their preferred schedule from a blank slate, the starting point is 50-50, and only clear evidence moves the needle.

Five states have already adopted similar presumptions. Kentucky enacted its equal-time presumption in 2018 under KRS § 403.270, and a 2023 University of Kentucky study found that shared custody arrangements in the state increased from 37% to 56% within three years of the law taking effect. Arkansas, West Virginia, Missouri, and South Dakota have since followed with their own versions. Mississippi would become the sixth.

How Mississippi Law Currently Handles Custody

Mississippi custody law sits primarily in Miss. Code Ann. § 93-5-24, which directs courts to consider the "best interest of the child" without specifying a particular custody arrangement as the starting point. The Albright factors — codified through decades of case law rather than statute — give chancellors broad discretion across 12 considerations including age of the child, health of the parents, continuity of care, and willingness to co-parent.

Mississippi also recognizes both "legal custody" (decision-making authority over education, healthcare, and religion) and "physical custody" (where the child lives day-to-day) as separate determinations under Miss. Code Ann. § 93-5-24(5). HB 1662 would affect the physical custody presumption while leaving legal custody analysis largely intact. Joint legal custody is already common in Mississippi — awarded in approximately 65% of cases according to Mississippi Chancery Court data — but joint physical custody with roughly equal overnights has been far less frequent.

The child support implications are equally significant. Under current Mississippi guidelines in Miss. Code Ann. § 43-19-101, support is calculated using the non-custodial parent's adjusted gross income with a percentage-of-income model: 14% for one child, 20% for two, 22% for three, 24% for four, and 26% for five or more. When parents share roughly equal time, HB 1662 would require courts to apply a modified offset formula — meaning both parents' incomes are considered, and the higher earner pays the difference. That adjustment could reduce child support obligations by 30-50% in many equal-time arrangements compared to current calculations, based on modeling from states that have adopted similar frameworks.

The Conference Committee Process

The bill is not yet law. On March 26, 2026, the Mississippi House declined the Senate's amendments to HB 1662, triggering the appointment of a conference committee. That committee — composed of members from both chambers — must produce a compromise version that both the House and Senate approve before the bill reaches Governor Tate Reeves's desk.

The Mississippi legislative session typically ends in early April, giving the conference committee a narrow window to reconcile the two versions. The primary disagreements involve the strength of the domestic violence exception and whether the presumption should apply retroactively to existing custody orders upon modification. The House version applies the presumption only to new cases filed after July 1, 2026, while the Senate version would extend it to modification petitions as well.

Practical Takeaways for Mississippi Parents

  1. No immediate changes to existing custody orders. Even if HB 1662 passes, current custody arrangements remain in place unless a parent files a modification petition demonstrating a material change in circumstances under Miss. Code Ann. § 93-5-24(9).

  2. Parents currently in custody disputes should monitor the conference committee outcome closely. If the bill passes with the Senate's broader language, parents with existing orders could petition for modification using the new 50-50 presumption as early as July 1, 2026.

  3. Document your parenting involvement now. Under a presumption framework, evidence of active parenting — school pickups, medical appointments, extracurricular involvement — becomes the baseline expectation rather than something to prove you deserve.

  4. Expect child support recalculations. If you currently pay or receive child support and your custody arrangement shifts to equal time, the modified offset formula could substantially change the support amount. Run the numbers with an attorney before agreeing to any new arrangement.

  5. The domestic violence exception is real and meaningful. HB 1662 explicitly removes the 50-50 presumption when a court finds substantiated domestic violence by either parent. If DV is a factor in your case, the traditional best-interest analysis applies, and the court retains full discretion.

Frequently Asked Questions

Does HB 1662 guarantee every parent gets 50-50 custody in Mississippi?

No — HB 1662 creates a rebuttable presumption, not a guarantee. Equal parenting time (approximately 182.5 overnights per year) becomes the starting point, but either parent can present evidence that a different arrangement serves the child's best interest. The presumption shifts the burden of proof, not the outcome in every case.

When would the new Mississippi 50-50 custody law take effect?

HB 1662 includes a July 1, 2026 effective date. The bill must first clear the conference committee, pass both chambers in final form, and receive the governor's signature. The Mississippi legislative session typically ends in early April 2026, making the next two weeks critical for the bill's fate.

How does the 50-50 presumption affect child support calculations in Mississippi?

The bill requires courts to apply a modified offset formula when parents share approximately equal time. Under current Miss. Code Ann. § 43-19-101 guidelines, the non-custodial parent pays 14-26% of adjusted gross income depending on the number of children. The offset model considers both parents' incomes and typically reduces support by 30-50% compared to a sole-custody calculation.

Can I modify my existing Mississippi custody order if HB 1662 passes?

Modification requires proving a material change in circumstances under Miss. Code Ann. § 93-5-24(9). Whether the new law alone qualifies as a material change depends on which version passes — the Senate version would apply to modifications, while the House version covers only new cases filed after July 1, 2026.

What happens in domestic violence cases under the new Mississippi custody presumption?

HB 1662 explicitly excludes cases involving substantiated domestic violence from the 50-50 presumption. When a court finds credible evidence of DV by either parent, the presumption is removed entirely, and the chancellor retains full discretion to determine custody based on the traditional Albright best-interest factors.

Mississippi families navigating custody decisions during this period of legal change should consult with a local family law attorney who can evaluate how the current law — and any changes from HB 1662 — apply to their specific circumstances.
