Mississippi lawmakers approved House Bill 1662 on April 1, 2026, sending the most significant custody reform in decades to Governor Tate Reeves for signature. The bill creates a rebuttable presumption that equal (50-50) joint custody serves the best interest of the child under Miss. Code Ann. § 93-5-24, rewrites child support calculations to compare both parents' incomes, and takes effect July 1, 2026, if signed — fundamentally changing how every contested custody case in Mississippi will be decided.

HB 1662 Replaces Judicial Discretion With a Statutory Starting Point
Under current Mississippi law, chancery court judges have broad discretion to award custody based on the Albright v. Albright factors — a 12-factor balancing test the Mississippi Supreme Court established in 1983. There is no statutory presumption favoring either parent or any specific timesharing arrangement. In practice, according to Mississippi Today, this discretion has produced wildly inconsistent outcomes across the state's 20 chancery court districts.
HB 1662 changes the default. The bill amends Miss. Code Ann. § 93-5-24 to create a rebuttable presumption that joint physical custody with equally shared parenting time is in the best interest of the child. This means chancery judges must start from a 50-50 baseline and require the opposing parent to present clear evidence justifying a departure.
This is a structural shift. Mississippi joins a growing national movement — Kentucky enacted a similar presumption in 2018, Arkansas followed in 2021, and at least 12 other states have introduced comparable legislation since 2023. The legal standard moves from "judge decides what seems best" to "equal time is the starting point, prove otherwise."
How Mississippi Custody Law Changes Under HB 1662
Mississippi's current custody framework rests on Miss. Code Ann. § 93-5-24, which directs courts to consider the best interest of the child without specifying a preferred arrangement. The Albright factors — including age of the child, health of each parent, continuity of care, moral fitness, and willingness to facilitate the other parent's relationship — guide judicial analysis but produce no predictable outcome.
HB 1662 adds a new layer on top of these factors. The bill requires chancery courts to:
- Begin with a presumption that joint custody with equal parenting time serves the child's best interest
- Apply the presumption as rebuttable — meaning either parent can present evidence to overcome it
- Consider domestic violence, substance abuse, and child endangerment as grounds for rebuttal
- Recalculate child support obligations using an income-comparison model that accounts for both parents' earnings and the time each parent has physical custody
The child support recalculation is particularly consequential. Mississippi currently uses the income-shares model under Miss. Code Ann. § 43-19-101, which calculates support based on combined parental income and the percentage each parent contributes. Under HB 1662, when parenting time is equal, the support obligation shrinks because both parents bear direct costs during their custodial periods. A parent earning $60,000 annually who previously paid $800 per month in support to a parent earning $35,000 could see that obligation reduced by 30-50% under a true 50-50 arrangement, depending on the final formula the bill adopts.
What This Means for Pending and Future Cases
The July 1, 2026, effective date creates an immediate strategic question for every Mississippi family law case currently in litigation. Cases filed before July 1 but not resolved by that date will likely face arguments about whether the new presumption applies. Mississippi courts generally apply procedural changes to pending cases while preserving substantive rights under existing law, but a rebuttable presumption arguably changes both procedure and substance.
For parents considering filing for divorce or custody modification, the timing matters. Filing after July 1 guarantees the new presumption applies. Parents who currently have primary custody and want to preserve that arrangement may benefit from resolving their cases before the effective date. Parents seeking more time with their children gain leverage by waiting.
Governor Reeves has not publicly indicated whether he will sign HB 1662. Mississippi governors have 5 days (excluding Sundays) to sign or veto a bill after it reaches their desk, per Miss. Const. Art. 4, § 73. If the governor takes no action, the bill becomes law without a signature.
Practical Takeaways for Mississippi Parents
-
If you are currently negotiating a custody agreement, understand that the legal landscape shifts on July 1, 2026. Any agreement finalized before that date operates under current law; any agreement after falls under the new presumption. Time your decisions accordingly.
-
If you are the primary custodial parent and want to maintain majority timesharing, you will need to present specific evidence — such as documented domestic violence, substance abuse, or the other parent's inability to provide adequate care — to overcome the 50-50 presumption after July 1.
-
If you are a noncustodial parent seeking more time, HB 1662 strengthens your position significantly. The burden shifts from proving you deserve more time to the other parent proving you should have less.
-
Review your child support obligations or expectations. Equal parenting time reduces — and in some income scenarios eliminates — traditional child support transfers. Budget planning should account for this change.
-
Document your parenting involvement now. Courts applying the new presumption will still evaluate each parent's capacity and history. School pickups, medical appointments, extracurricular involvement, and day-to-day caregiving all become evidence supporting or undermining the presumption.
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. The 50-50 split is the starting point, but either parent can present evidence — such as domestic violence, substance abuse, or a child's special needs — to convince the chancery court that a different arrangement better serves the child's interest under Miss. Code Ann. § 93-5-24.
When does Mississippi's new custody presumption take effect?
HB 1662 takes effect July 1, 2026, if Governor Tate Reeves signs the bill. The governor has 5 days (excluding Sundays) to act after receiving it. Cases filed or modified after July 1 will be subject to the new 50-50 presumption. Cases resolved before that date remain under current Albright factor analysis.
How will HB 1662 change child support calculations in Mississippi?
HB 1662 introduces an income-comparison model that accounts for both parents' earnings and custodial time. Under current Miss. Code Ann. § 43-19-101 guidelines, the noncustodial parent pays based on income share. With equal parenting time, support obligations decrease significantly — potentially 30-50% — because both parents bear direct costs during their custodial periods.
Can I modify an existing Mississippi custody order under HB 1662?
Yes, but modification requires showing a material change in circumstances under Miss. Code Ann. § 93-5-24. The passage of HB 1662 alone may qualify as a change in law sufficient to support a modification petition after July 1, 2026, though Mississippi appellate courts have not yet addressed this question.
What evidence overcomes the 50-50 presumption in Mississippi?
Documented domestic violence, substance abuse, child neglect, incarceration, or a parent's demonstrated inability to provide a safe and stable home environment can rebut the presumption. The opposing parent must present this evidence to the chancery court; the judge retains discretion to order a different arrangement when the evidence warrants departure from equal time.
