Mississippi is on the verge of a generational change in family law. House Bill 1662, which passed both legislative chambers with zero opposition (118-0 in the House), creates a rebuttable presumption that equal parenting time serves a child's best interests. Governor Tate Reeves faces an April 13, 2026 deadline to sign or veto the bill. If enacted, Mississippi becomes the sixth state to adopt this standard, effective July 1, 2026.

Why This Bill Rewrites Mississippi Custody Law
HB 1662 fundamentally reverses how Mississippi courts approach custody disputes. Under current Miss. Code Ann. § 93-5-24, Mississippi law states there is no presumption favoring maternal custody and recognizes joint custody only when both parents agree to it. In practice, according to Father & Co., Mississippi courts have historically tilted toward primary-parent arrangements that favor mothers, particularly for young children.
The new framework starts every custody case at a 50-50 baseline. That is not a suggestion or a factor to weigh. It is a legal presumption that judges must follow unless one parent presents evidence meeting specific statutory exceptions. A court that deviates from equal parenting time must document its reasoning in writing, creating an appellate record that did not previously exist in Mississippi custody proceedings.
The unanimous 118-0 House vote is remarkable in any legislative context, but especially so for a custody bill. Family law reform has historically been one of the most contentious areas of state legislation, with organized opposition from bar associations, domestic violence advocacy groups, and judicial conferences. The fact that HB 1662 drew zero opposition in either chamber suggests Mississippi lawmakers viewed the current system as fundamentally broken.
How Mississippi Law Currently Handles Custody
Mississippi's existing custody framework under Miss. Code Ann. § 93-5-24 uses a multi-factor best-interest analysis drawn largely from the 1983 Mississippi Supreme Court decision in Albright v. Albright. Courts weigh roughly a dozen factors including the age and health of the child, each parent's moral fitness, stability of the home environment, and continuity of care.
The problem family law practitioners have identified is discretion without guardrails. Two judges in the same courthouse can reach opposite conclusions on nearly identical facts because the Albright factors carry no mandatory weight. The result is unpredictable outcomes that incentivize litigation rather than settlement.
HB 1662 addresses this by establishing a clear starting point. Under the new law, courts must begin with the presumption that joint custody with equally shared parenting time is in the best interest of the child. The bill preserves five specific grounds for deviation:
- A history of domestic violence by either parent
- Substance abuse that endangers the child
- Child abuse or neglect
- Geographic impracticality (parents living far apart)
- Other factors the court documents in writing as contrary to the child's best interest
Mississippi would join Kentucky (which adopted its presumption in 2018 under KRS § 403.270), Arkansas, West Virginia, Florida, and Missouri as the sixth state with a rebuttable equal-parenting presumption.
What Changes for Child Support Under HB 1662
The bill also restructures how Mississippi calculates child support in shared-custody arrangements. Under current Mississippi child support guidelines, the non-custodial parent pays a percentage of adjusted gross income (14% for one child, 20% for two, and so on). That formula assumes one parent has primary custody and the other has visitation.
Under HB 1662, courts would compare both parents' incomes and calculate the difference for support purposes, per Mississippi Today. This income-differential approach recognizes that when both parents share roughly equal time, both are bearing direct costs of raising the child. The higher-earning parent would still pay support, but the calculation reflects actual parenting time rather than a primary-versus-secondary framework.
For Mississippi families, this means child support orders in contested cases could look significantly different after July 1, 2026. Parents earning similar incomes who share 50-50 time might see minimal support obligations, while cases with large income disparities would still produce meaningful support orders.
Practical Takeaways for Mississippi Parents
-
If you have a pending custody case that will not be finalized before July 1, 2026, discuss with your attorney whether the new presumption changes your litigation strategy. Cases filed under current law but decided after the effective date may be subject to the new standard.
-
Parents who previously received less than 50% parenting time may have grounds to seek a modification after July 1, 2026. A change in the law can constitute a material change in circumstances sufficient to reopen a custody order under Mississippi modification standards.
-
Document your parenting involvement now. Under a 50-50 presumption, the parent seeking to deviate from equal time bears the burden of proof. Evidence of consistent, active parenting (school involvement, medical appointments, extracurricular activities) strengthens your position under the new framework.
-
Understand that 50-50 does not mean one rigid schedule. Equal parenting time can take many forms: week-on/week-off, 2-2-3 rotations, or other arrangements totaling roughly 182.5 days per parent annually. Courts retain discretion to craft schedules that serve the child's practical needs.
-
If domestic violence, substance abuse, or abuse/neglect is a factor in your case, the rebuttable presumption works in your favor. HB 1662 specifically carves out these exceptions, and the burden shifts to the other parent to prove equal time is appropriate despite documented safety concerns.
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. Mississippi courts must start at 50-50 as the baseline under the amended Miss. Code Ann. § 93-5-24, but judges can deviate when evidence supports one of five statutory exceptions including domestic violence, substance abuse, or geographic impracticality. The parent seeking to deviate bears the burden of proof.
When does the new Mississippi custody law take effect?
HB 1662 takes effect July 1, 2026, if Governor Reeves signs it or allows it to become law without his signature. The governor faces an April 13, 2026 deadline to act. Cases decided after the effective date will be subject to the new 50-50 presumption under Miss. Code Ann. § 93-5-24, even if filed earlier.
Can I modify my existing Mississippi custody order under the new law?
Yes. A statutory change of this magnitude is likely to qualify as a material change in circumstances under Mississippi modification standards. Parents who received less than 50% parenting time under the old Albright factor analysis can petition for modification after July 1, 2026. Courts will apply the new presumption to the modification hearing.
How does HB 1662 affect child support calculations in Mississippi?
HB 1662 shifts Mississippi child support from a percentage-of-income model (14% for one child under current guidelines) to an income-differential approach for shared-custody cases. When parents share roughly equal time, courts compare both incomes and calculate support based on the difference, which typically results in lower support obligations than the current non-custodial-parent formula.
Which other states have adopted a 50-50 custody presumption?
Five states currently have rebuttable presumptions favoring equal parenting time: Kentucky (adopted 2018), Arkansas, West Virginia, Florida, and Missouri. Mississippi would become the sixth state with this standard if HB 1662 is signed. South Carolina is also considering similar legislation in its 2026 session, according to WLTX.
